The present invention relates to a vacuum sewer system, which contains plumbing node, such as the toilet, vacuum sewer pipe attached to the plumbing node, the exhaust valve between plumbing node and the vacuum sewer piping, and a device for creating a vacuum to create a vacuum in the vacuum sewer piping, in accordance with the introductory part of paragraph 1. The present invention also relates to a method of the vacuum sewer system in accordance with the introductory part of paragraph 9.

Well-known vacuum sewer system, in particular a vacuum toilet system. At the first stage of development of the vacuum sewer system typically includes a drain tank of large volume, in this system, the tank was maintained under vacuum to provide vacuum to the vacuum sewer piping. The vacuum was maintained in the waste-holding tank large amount by using a separate vacuum pump. Wastewater was discharged from the drain tank through the sewage pump attached to the bottom of the drain tank. Due to the large volume drain tank such systems require a lot of space, which is usually not available, for example, trains, marine vessels and aircraft. An example of such a solution is described, for example the EP, in EP 0 330 490.

At a later stage appeared jet system in which the wastewater is circulated from the sump tank of large volume to gidrostroya pump facing the same drain tank. Gidrostroy pump had input connected to the vacuum sewer piping and additionally plumbing nodes, such as toilets. The wastewater is circulated through Gidrostroy pump, whereby Gidrostroy pump created a vacuum in the vacuum sewer piping for directing wastewater from the toilet to drain the tank. This solution requires a lot of space. Moreover, it has a low degree of efficiency. Such a solution is known, for example, from EP 0 653 524.

Other developments include a liquid ring pump, which is attached to the drain Baku large amount, whereby a vacuum is established and wastewater pumped by the same pump in an alternative way, for example as in EP 0 287 350.

Another solution with a single-stage pump is described in EP 0 644 299. This solution contains protected from moisture with a dry centrifugal vane pump creates a vacuum in the waste-holding tank of large volume. This tank is emptied by reversing the pump so that the discharge side of the pump is connected with the drain tank has a large capacity for its devastation by displacing the article is cnyh water in another place under the action of compressed air. This solution also requires a lot of space, and, moreover, this pump is very sensitive to any moisture that require complex control mechanisms.

Linear system equipped with a liquid ring pump that creates a vacuum and pumping wastewater directly from the vacuum sewer piping, also known and described, for example, in EP 0 333 045 and EP 0 454 794. Additional linear solution is described, for example, in EP 1 172 492. In such linear systems using one single-stage pump that creates a vacuum and suction of waste water at the same time. These solutions represent attempts to reduce the required space by eliminating the intermediate drain tank of large volume, i.e. tank, located between the pump and the vacuum sewer piping.

The last solution with linear pumps with dual function - the creation of a vacuum by suction air and the simultaneous absorption of wastewater, however, are not highly effective. Moreover, they are subject to functional disorders. The pumps used in this context, are intended either for inflating air or inflation fluid, so the transportation of both air and liquid, as a rule, is not very efficient.

This is due to typeclassopedia the functions of vacuum sewer system, in particular, vacuum toilet system, where the waste water is transported through the vacuum sewer pipe in the form of tubes, with intermediate large volumes of air, forming a heterogeneous wastewater stream.

When the vacuum toilet merges by actuation function drain, exhaust valve between the vacuum toilet tank and the vacuum sewer piping is opened, and the vacuum prevailing in the vacuum sewer piping, removes sewage and drain water from the bowl into the vacuum sewer pipe. Only a small amount of drain water is required, due to the strong suction effect of the vacuum sewer pipe and the atmospheric pressure prevailing in (and around) vacuum toilet tank. The number of sewage and drain water, as a rule, is about 2 liters.

Therefore, there is a difference of pressure, i.e. atmospheric pressure on the side of the toilet tank regarding sewage and drain water and vacuum side of the vacuum sewer pipeline regarding sewage and drain water when the exhaust valve opens. Transportation of sewage and drain water is due to this pressure difference, whereby the sewage and drain water form a single tube, for that what should be a large amount of air, for example, about 2 liters of sewage and drain water, followed by about 60 liters of air, i.e. sewage and drain water amount ratio of 1:30 to the air. A large amount of air is drawn or forced in the vacuum sewer piping, since the exhaust valve remains open for a certain period of time.

The vacuum sewer piping, essentially, has a relatively small diameter, which contributes to the maintenance of the education of the tubes, which, again, is necessary to maintain the pressure difference (low-pressure front and high pressure behind the individual tubes)required for transportation. During transport through the vacuum sewer pipe, tube has a negative impact force of gravity, and they rasprashivaete after some time in a horizontally located the pipeline. It evens out the pressure, whereby the necessary pressure difference described above, before and after individual tubes disappears. To re-establish the pressure difference for transporting sewage, vacuum sewer pipe equipped with lower points or pockets into which the wastewater is accumulated for re-formation of individual tubes.

This chain of individual tubes and air, the particular in a ratio of about 1:30, which generates a wastewater stream in a vacuum sewer system, it is difficult to pump with high efficiency.

The present invention is the provision of a vacuum sewer system, which can avoid the above mentioned problems, and which provides efficient transport of wastewater by means of the pumping device, reducing the occupied space. These tasks are achieved with the help of a vacuum sewer system in accordance with paragraph 1 and by way of the vacuum sewer system in accordance with paragraph 9.

The basic idea of the invention is to stay within the linear solution, to resolve any intermediate drain tanks of large volume, and in order to remove the impurity (together with drain water) and the air in the same proportion (1:30), as was or is in a vacuum sewer system, as described above.

Vacuum sewer system contains a linear separation device in the vacuum sewer piping, and the first pumping device and the second pumping device connected in parallel to the line separating device. The first pumping device is a vacuum pump for creating vacuo is in the vacuum sewer piping and intake air from the wastewater stream, proceeding in a linear separating device of a vacuum sewer piping, and a second pumping device is intended for inflation, mainly sewage from the wastewater stream flowing in line separating device of a vacuum sewer pipeline.

The combination of the two pump devices of different types can effectively pump up the uneven flow of wastewater transported by the vacuum sewer piping. Parallel connection of the pumping devices requires that the division effectively carried out inside a small space, i.e. within the linear separation device. The division is essentially continuous, since the waste water does not accumulate in a linear separation device. Linear separation device is designed to separate air from impurities in the linear separation device.

Preferably, the first valve device is located on the suction side of the vacuum pump, between the vacuum pump and linear separation device. This is done mainly to ensure that the vacuum pump will not pump fluid.

Linear separation device is preferably equipped with a level indicator on top of the spine, which is used to control the operation of the first valve device mentioned above. It additionally helps to ensure that the vacuum pump will not pump fluid. Additionally, the indicator surface can be used to monitor the operation of the second pumping device, in particular, that the impurity is not accumulated in a linear separator.

When the flow of wastewater containing sewage and drain water, and air flows in a linear separation device, it is preferable to ensure that the liquid part proceeded to the second pumping device, and the air is naturally rose to the vacuum pump. This is achieved by equipment outlet of the vacuum sewer pipe extending in a linear separation device directed to the second pumping device.

The second pumping device comprises a liquid pump. For the efficient operation of the vacuum sewer system, the pump must be able to pump up the air, at least to some extent. Therefore, determination of the liquid pump in this context should be understood as a pump, pumping mostly liquid, and also has the ability to pump up the air, at least, is certain degree. In independent clauses 1-8 determined that "the second pumping device is intended for inflation, mainly sewage"that must mean that the second pumping device must be able to pump a bit of air. In other words, it can be classified as a vacuum pump, which can pump fluid. This second pump must be able to exercise also pumping from a source in the state of vacuum or under pressure. A liquid pump in this context may represent a self-priming pump, kolovraty pump, liquid ring pump, and the like.

To ensure modernizing already existing vacuum sewer systems, the second pumping device may include Gidrostroy pump and a liquid pump connected to the circulation Baku, and the liquid collected in the circulation tank is circulated through a liquid pump to gidrostroya pump to achieve the effect of suction for pumping mainly sewage from the wastewater stream, flowing in a linear separation device, and further inflating the above-mentioned impurities in the circulation tank. Thus, the advantages of the present invention can be achieved also in the already used C themes.

Vacuum sewer system preferably contains a pressure sensor that is attached to the vacuum sewer piping, which can be used to control the operation of two pumps connected in parallel to the line separating device.

The first pumping device and the second pumping device to work consistently, so that continuous or more or less continuous separation of the wastewater stream is provided by a linear separation device. Impurity does not accumulate in a linear separation device, and continuity depends on the degree of use of the vacuum sewer system.

In the method in accordance with the invention to control the vacuum sewer system uses a single linear separation device in the vacuum sewer piping, whereby the flow of wastewater is transported through the vacuum sewer pipe. Linear separation device separates the air from the impurities from the wastewater stream flowing in line separating device of a vacuum sewer pipeline.

The first pumping device in the form of a vacuum pump creates a vacuum in the vacuum sewer piping and remove the air from the wastewater stream, rotateimage in line separating the device from the vacuum sewer piping, and the second pumping device connected in parallel with the first pump device to the line dividing device, and pumps, mainly sewage from the wastewater stream flowing in line separating device of a vacuum sewer pipeline. This enables the use of each pump for inflating the environment for which it was intended. Linear separator separates the air from the sewage in a linear separator.

The method further uses the first valve device on the suction side of the vacuum pump, between the vacuum pump and linear separation device. By a suitable synchronization operation, the second pumping device can be used for efficient pumping of sewage and drain water, and vacuum pump can be controlled so that it created a vacuum or took the air if necessary. Specified the first valve device is used as the preferred security measures to ensure that sewage and drain water does not get into the vacuum pump.

The preferred embodiment of the method of operation of a vacuum sewer system are given in paragraphs 8-14.

Hereinafter the invention will be described, only by way of example, with reference to the accompanying schematic drawings, in which the s:

figure 1 shows the General layout of the vacuum sewer system,

figure 2 shows a first embodiment of a linear separator with two pump devices connected in parallel, and

figure 3 shows a second embodiment of a linear separator with two pump devices connected in parallel.

The present invention relates to a vacuum sewage system 100, an example of which is schematically shown in figure 1. Vacuum sewage system 100 includes a bathroom, for example the toilet 101, and the vacuum sewer piping 200 attached to the plumbing site. The vacuum sewer piping 200, as shown in the drawings, includes a header 201, the first main line 202 and the second main pipe 203, and branch piping 204 leading to each of plumbing nodes.

Plumbing node may also represent, for example, urinal 102, washbasin 103, shower node 104, etc. Every plumbing node attached to the vacuum sewage pipe, or, as shown, to the branch piping 204, through the exhaust valve (not shown). Vacuum sewage system further includes a device for creating a vacuum 300 for creating a vacuum in the vacuum canalizes the main objective of the pipeline 300.

In this regard, the definition of the device to create a vacuum should be understood only as an abstraction. In a vacuum sewage system, sewage is collected from plumbing nodes that are transported through the vacuum sewer piping with vacuum created by the device to create a vacuum of 300, and then transported through the device to create a vacuum, for example, in samotechny sewer system or in another place where thrown out of the filth. This is not shown in the drawings.

The first main pipe 202 is attached to the manifold 201 using the first shut-off valve 211 and the second main pipe 203 is attached to the manifold 201 by means of the second shut-off valve 212. Collector 201 is connected to the device to create a vacuum 300 with a third shut-off valve 210. Collector 201 is equipped with a pressure sensor 400.

Basically vacuum sewer system works as follows.

Device for creating a vacuum 300 creates a vacuum in the vacuum sewer piping 200, mainly to the (high) level of vacuum, for example up to approximately 0.5 bar, after which the device to create a vacuum can be stopped. When, for example, the toilet 101 merges, exhaust valve (not shown) between the bowl 101 and branch piping 204 opens, through h the th sewage and drain water pumps in the vacuum sewer piping 200, in this case, the branch piping 204, and followed by a large volume of air due to the pressure difference between the vacuum in the vacuum sewer pipe and the atmospheric pressure prevailing in the toilet bowl 101 and around it. Sewage and drain water take the form of a separate tube, and the transportation of the individual tubes is carried out on the basis of the above differential pressure, low pressure ahead of a separate tube and a higher pressure behind the individual tubes. This was described in more detail above.

Some time later, after using the lavatory, for example, after draining the bowl 101, washbasin 103 or 104 soul, the vacuum level in the vacuum sewer piping 200 is reduced. When it reaches a certain (low) level, for example, about 0.35 bar, a device for creating a vacuum 300 starts to restore or re-create the vacuum of a certain (high) level, for example, about 0.5 bar, as mentioned above. The pressure level in the vacuum sewer piping 200 is monitored by the pressure sensor 400, which can be used for activation or deactivation of the device to create a vacuum.

Such vacuum sewer systems are well known in the art and therefore not described in more p is fractionally.

The pressure levels shown above are only illustrative examples.

In the present invention, the vacuum sewer system additionally includes a linear separation device 1 (Figure 2 and Figure 3) in the vacuum sewer piping 200, this linear separation device is connected parallel to the first pumping device 2 and the second pumping device 3. These two pumping devices indicated only schematically in figure 1.

Figure 2 shows the first embodiment of the linear separation device 1 with two pump devices connected in parallel to the line separator device 1. While the first pumping device 2 is a vacuum pump that is attached to the line separator device 1 by means of pipe 21 equipped with a first valve device 22, a shut-off valve located on the suction side of the vacuum pump, between the vacuum pump and line separator device 1. This is the first valve device 22 is not necessary for the correct operation of the design, but is preferred as a safety element. The second pumping device 3 is a liquid pump, which should also have the ability of the Yu to pump up the air, with its suction side connected with the line separator device 1 by means of pipe 31. These two pumping devices are defined and described in more detail below.

Linear separation device 1 is located in the vacuum sewer piping 200. With special reference to Figure 1, it is in connection with header 201, whereby the flow of wastewater in the form of a chain of separate tubes, followed by large volumes of air (as described above) occurs in a linear separation device 1 during the transportation of sewage in the vacuum sewer system. The vacuum sewer piping 200, or, in this case, collector 201, has an outlet 205 extending in a linear separation device 1. The outlet 205 is preferably directed to the second pumping device 3, in particular, to the pipe 31 connecting the second pump device 3 with the line separator device 1. This helps to avoid direct transportation of liquid or moisture to the first pumping device 2.

Linear separation device 1 is equipped with indicator 11 level surface for tracking the level of wastewater in the linear separation device 1 to avoid accumulation of impurities in the linear separation device is TBE.

Further, the vacuum sewer system, which uses linear separation device with two pumping devices connected to it in parallel will be described with reference to the embodiment from Figure 2.

When the desired vacuum level, for example, given the high level of about 0.5 bar, as described above, it is necessary to create in the vacuum sewer piping 200, the second pumping device 3 first run to ensure that it drains any sewage and drain water possibly present in the linear separation device 1, through the pipe 31. After an adjustable delay, for example, a couple of seconds, opens the first valve device 22, whereby the vacuum pump is started to create the desired vacuum in the vacuum sewer piping 200. For the vacuum level is monitored by the pressure sensor 400, and when the desired vacuum level (high) is reached, the first valve device 22 is closed. The first pumping device 2 can then be stopped at the same time, or after an adjustable delay, for example, about 15 seconds. It depends on the frequency of use of the vacuum sewer system. If it is expected that the vacuum level may be reduced for a short period of time due to high frequency of use, per the second pumping device 2 can be maintained to avoid frequent restarting of the first pumping device 2. The second pumping device 3 continues to operate for some time to remove any dirt and water that may remain in the linear separation device 1. Linear separation device 1 is not designed to collect or accumulate dirt. For the efficient operation of the vacuum sewer system, the first pumping device 2 does not work, if the second pumping device 3 does not work.

When the vacuum sewer system is used, for example, by draining the bowl 101, use of the urinal 102, sink 103 or shower 104, the pressure in the vacuum sewer piping 200 falls. When the vacuum level reaches a certain low value, for example, about 0.35 bar, as described above, the desired vacuum level must be restored to ensure the transporting function of the vacuum sewer system.

If this happens when the vacuum pump still running, for example, within an adjustable delay of about 15 seconds, as indicated above, the second pumping device 3 first starts and runs for a short period, after which the first valve device 22 is opened to the vacuum pump could restore the desired level of vacuum in the vacuum sewer piping 200.

If bravenewcode in the vacuum sewer pipe reaches a predetermined low level after stopping the vacuum pump, the second pumping device 3 first starts and runs for some time, after which the first valve 22 is opened and the vacuum pump is started after an adjustable delay to increase the vacuum level in the vacuum sewer piping 200 to a specified high value, i.e. to the desired level.

The principle of operation of linear separation device 1 is in the permanent separation of sewage and drain water from air in the wastewater stream, flowing in a linear separation device 1 of the sewer pipeline 200. Thus, each of the two pumps can be effectively used for inflating medium to inflate which they are intended.

The second pumping device 3 pumps sewage and drain water from the wastewater stream, and the first pumping device 2, the vacuum pump sucks the air from the sewer pipeline 200, partly to create a vacuum and partially to remove air from the wastewater stream. The first pumping device 2 and the second pumping device 3 are sequentially so that a line separator device 1 is ensured continuous or more or less continuous separation of the wastewater stream. Impurity does not accumulate in a linear separation device 1, and continuously the t depends on the level of frequency of use of the vacuum sewer system.

The objective of the first valve device 22 is to prevent the passage of any liquid in the vacuum pump. Linear separation device 1 is also equipped with a level indicator surface 11, which monitors the level of the sewage and drain water in a linear separation device 1. The second pumping device 3 is always triggered when the indicator surface 11 shows the specified level of wastewater in the linear separation device 1. Also, the first pumping device 2 does not start when specified above specified level of wastewater. The indicator surface 11 is also preferably connected with the first valve device 22, for example, with a drive valve to control its operation. This further ensures that a particular pump pumps only the environment for which it was intended. An additional measure for this purpose is that the output of the outlet 205 of the vacuum sewer piping 200, or collector 201, the linear separator 1, is directed to the second pumping device 3.

Vacuum sewer system works properly even without the first valve device 22 due to the effective separation of air from the sewage and drain water in a linear separation device. Per the second valve device is used, basically, as a safety measure. Control of the vacuum and the flow of sewage in the vacuum sewer piping can be performed using the first, second and third shut-off valves 211, 212 and 210.

The intake air vacuum pump, can be damp, therefore it is preferable to attach a device for removing condensate through the valve device to the discharge side of the vacuum pump, to remove any condensate formed.

The second pumping device 3 can preferably be equipped with a temperature sensor to prevent overheating. Pumping device stops when the temperature is too high, for example, in case of operation without lubrication.

The basic idea of the invention is to stay within the linear system. Therefore, the waste water collected from sanitary nodes that are transported through the vacuum sewer piping 200 and line separator device 1 and by means of the second pump device 3 further to, for example gravity sewer or other place where discarded wastewater is collected. This is not shown in the drawings.

The pressure levels and the periods given above are only illustrative examples.

Figure 3 shows the second embodiment of the linear R is deletelog device 1 with two pump devices, connected in parallel to the line separator device 1. The first pumping device 2 is a vacuum pump, coupled with a linear separation device 1 by means of pipe 21 equipped with a first valve device 22, a shut-off valve located on the suction side of the vacuum pump, between the vacuum pump and line separator device 1. The second pumping device 3 is attached to the line separator device 1 by means of pipe 31. The second pumping device 3 contains Gidrostroy pump 32 and the liquid pump 36 connected to the circulation tank 38. The liquid collected in the circulation tank 38, circulates through the liquid pump 36 to gidrostroya pump 32 to create suction in the pipe 31 for inflation, mainly sewage from the wastewater stream flowing in line separating device 1, and then into the circulation tank 38. The second pumping device 3 corresponds to the inkjet system. These two pumping devices are defined and described in more detail above.

Linear separation device 1 is placed in the vacuum sewer piping 200. With special reference to Figure 1, it is located in the reservoir 201, whereby the flow of sewage in the form of price the glasses separate tubes, followed by large volumes of air (as described above) occurs in a linear separation device 1 due to the transportation of sewage in the vacuum sewer system. The vacuum sewer piping 200, or, in this case, collector 201, has an outlet 205 extending in a linear separation device 1. The outlet 205 is directed to the second pumping device 3, in particular, to the pipe 31 connecting the second pump device 3 with the line separator device 1. This helps to prevent the direct passage of liquid or moisture to the first pumping device 2.

Linear separation device 1 is equipped with a level indicator surface 11 to monitor the level of impurities in the linear separation device 1 to avoid accumulation of impurities in the linear separation device.

Next will be described the operation of the vacuum sewer system, which uses linear separation device with two pump devices, connected in parallel, with reference to the embodiment from Fig 3.

When the desired vacuum level, for example, given the high level of about 0.5 bar, as described above, it is necessary to create in the vacuum sewer piping 200, the second pumping device 3 SP the ditch runs to ensure that it pumps out any sewage and drain water that may be present in the linear separation device 1, through the pipe 31. After an adjustable delay, for example, a couple of seconds, the first valve device 22 is opened, whereby the vacuum pump is started to create the desired vacuum in the vacuum sewer piping 200. The vacuum level is monitored using the pressure sensor 400, and when the desired (high) level of vacuum is reached, the first valve device 22 is closed. The first pumping device 2 can then be stopped at the same time, or after an adjustable delay, for example, about 15 seconds. It depends on the frequency of use of the vacuum sewer system. If it is expected that the level of vacuum may be reduced within a short period of time due to high frequency of use, the first pumping device 2 can continue to work to avoid frequent restarting of the first pumping device 2. The second pumping device 3 continues to operate for some time to remove any dirt and water that may have remained in the linear separation device 1. Linear separation device 1 is not designed to collect or accumulate dirt. For effective work in chumney sewer system, the first pumping device 2 does not work, if it does not work the second pumping device 3.

The second pumping device 3 in this embodiment is as follows. First, it takes a certain level of liquid in the circulation tank 38 so that the liquid pump 36 could work properly. When the second pump device 3 is actuated, the liquid pump 36 is started, whereby he pumps the fluid from the circulation container through pipe 35. This fluid is then pumped in Gidrostroy pump 32, and exits the ejector 33 in the circulation tank 38. This creates a suction effect at the suction end 34 geostring pump 32 and further into the pipe 31, which thus removes sewage and drain water from the line separator device 1.

Thus, the present invention can be applied as an upgrade to the existing vacuum sewer systems of the prior art is very simple and effective way.

Therefore, as described with reference to Figure 2 above, when the vacuum sewer system is used, for example, by draining the bowl 101, use of the urinal 102, sink 103 or shower 104, the pressure in the vacuum sewer piping 200 pada is so When the vacuum level reaches a certain low value, for example, about 0.35 bar, as described above, the desired vacuum level must be restored to ensure the transport function of the vacuum sewer system.

If this happens at a time when the vacuum pump still running, for example, within an adjustable delay of about 15 seconds, as mentioned above, the second pumping device 3, i.e. the liquid pump 36, first starts and runs for a short period of time, after which the first valve device 22 is opened to the vacuum pump could recreate the desired vacuum level in the vacuum sewer piping 200.

If the vacuum level in the vacuum sewer pipe reaches a certain low level after stopping the vacuum pump, liquid pump 36 first starts and runs for some time, after which the first valve 22 is opened and the vacuum pump is started after an adjustable delay to increase the vacuum level in the vacuum sewer piping 200 to the specified high level, i.e. to the desired level.

The principle of operation of linear separation device 1 is continuous separation of sewage and drain water from air in the wastewater stream flowing in inane separation device 1 of the sewer pipeline 200. Thus, each of the two pumps can be effectively used for inflating medium to inflate which it was intended.

The second pumping device 3, a liquid pump 36 with Gidrostroy pump 32 is pumped sewage and drain water from the wastewater stream, and the first pumping device 2, the vacuum pump sucks the air from the sewer pipeline 200, partly to create a vacuum, and partly to extract air from the wastewater stream, flowing in a linear separating from the reservoir 201. The first pumping device 2 and the second pumping device 3 are sequentially so that a continuous or more or less continuous separation of wastewater flow was provided by a linear separation device 1. Sewage is not collected in a linear separation device 1, and the continuity depends on the frequency of use of the vacuum sewer system.

The objective of the first valve device 22 is to avoid any liquid in the vacuum pump. Linear separation device 1 is also equipped with indicator 11 level surface, which monitors the level of the sewage and drain water in a linear separation device 11. Indicator 11 level surface is also preferably connected to the first choice of the valve device 22, for example, the actuated valve to control its operation. Liquid pump 36 is always triggered when the indicator 11 level surface shows the specified level of impurities in the linear separation device 1. Also, the vacuum pump does not start when specified above specified level of impurities. This further ensures that the corresponding pump pumps only environment for which it was intended. An additional measure for this purpose is the location of the outlet 205 of the vacuum sewer piping 200, or collector 201 extending in a linear separation device 1, in the direction of the pipe 31 leading to the second pumping device 3.

Vacuum sewer system works properly even without the first valve device 22 due to the effective separation of air from the sewage and drain water in a linear separation device. The first valve device is used primarily as a safety measure. Control of the vacuum and the flow of sewage in the vacuum sewer piping can be performed using the first, second and third shut-off valves 211, 212 and 210.

The intake air vacuum pump, can be damp, therefore it is preferable to attach the device to-the Oia condensate through the valve device to the discharge side of the vacuum pump, to remove any condensate formed.

The basic idea of the invention is to stay within the linear system. Therefore, the waste water collected from sanitary nodes that are transported through the vacuum sewer piping 200 and line separator device 1 and then through the second pumping device 3 and from the circulating tank 38 to, for example, gravity sewer or other place where discarded wastewater is collected. This is not shown in the drawings.

The pressure levels and the periods given above are only illustrative examples.
