The invention relates to the field of ecology and improves the quality of decontamination fluids (e.g., drinking and waste water, milk, fruit juices, wine, beer, etc), improve the environment and environmental safety, reduce the cost and time required for decontamination, to keep useful quality decontaminate liquids.

A known method for decontamination of surfaces of solid objects decompression using chemically neutral gas, including gasanalysis intracellular fluid of microorganisms present on the surface to be disinfected objects, and its sharp Ratnasiri (patent No. 2045150 And 01 F 25/00).

The disadvantage of this method is that it can be used to disinfect only the surface of solid objects, and for disinfecting liquids it is not applicable.

The closest analogue to the claimed method according to the destination and aggregate similar essential features is a method of disinfecting fluid, including the destruction of cells present in microorganisms decompression created by-pass pre-gas saturated liquid from the tank with high pressure in a container with less pressure (EN 2114791, 10.07.98, C 02 F 3/02).

The disadvantage of this method is the lack of technology parameters saturation and p is thrasymene fluid, providing high-quality disinfection at optimum cost and time.

The purpose of the proposed method is to eliminate these disadvantages, that is simpler and cheaper technology for decontamination fluid, reducing time and costs.

This goal is achieved by the fact that in the proposed method, including the destruction of cells present in microorganisms decompression, created by the bypass pre-gas saturated liquid from the cavity with high pressure into the cavity with less pressure, decontaminate liquid is saturated with air in a sealed container under positive pressure of not less than 3 kg/cm2, can withstand the gas-saturated liquid at this pressure for not less than 60 minutes, after which perepuskat her capacity saturation capacity Ratnasiri communicated with the atmosphere through holes with a diameter of 0.5 to 1.5 mm with a constant differential pressure of not less than 3 kg/cm2why in the capacity of saturation continuously served the air volumetric flow rate not less than the volumetric flow return the fulfilled decontaminate liquid.

The set of essential features of the proposed method exhibits new properties, namely, that the disinfecting liquid to produce affordable gas (air), the quality of Bessarabian what I provide specific technology parameters (pressure and time of saturation and Ratnasiri decontaminate liquid), specific characteristics of the elements of the installation (the diameter of the bypass hole, the size and characteristics of the units).

Thus, the set of essential features of the proposed method meets the criteria of "significant differences" and "novelty."

The feeding of the gas intracellular fluid microorganisms significantly more time saturation decontaminate liquid because the intracellular fluid of the microorganisms are separated from the saturating gas cell membrane (cell wall) and not in contact with him. Different microorganisms have different size of cells, different shape, different thickness, density and strength of the walls of cells (membrane) and the like, so gasanalysis their intracellular fluid in each case (for each specific microorganism) requires a different value of external pressure and different exposure times under that pressure.

The use of more soluble in the liquid saturating gas helps reduce pressure and/or reduce the required exposure time to be disinfected fluid under pressure, i.e. allows to simplify the technology and accelerate the decontamination decompression. For example, if instead of air to apply the carbon dioxide, which is 33 times more and faster is dissolved in a liquid, or a mixture of Vozduha, it is possible to significantly reduce the required external pressure and the desired dwell time of the fluid under pressure (the feeding of the intracellular fluid of microorganisms).

The disinfecting liquid according to the invention is produced as follows.

At the first stage gasanalysis decontaminate fluid and intracellular fluid are microorganisms air at a pre-selected pressure for a preselected time until an equilibrium state, in which is dissolved in the intracellular fluid of microorganisms required for the destruction of their cell threshold decompression of the amount of air (for example, for the destruction of cells of Staphylococcus they need to withstand air pressure of not less than 3 kg/cm2for at least 60 minutes).

In the second stage sharply ratnasamy intracellular fluid of these microorganisms sharp decrease in the liquid pressure (external pressure for cells of microorganisms)in which of the intracellular fluid is artificially organized threshold decompression sharply distinguished dissolved air, which initially stretches and then breaks the shell of cells (destroy microorganisms).

Gasanalysis intracellular fluid of microorganisms present in disinfected fluid, can produce two VA is Yantai. The most viable option is chosen in relation to existing conditions, opportunities, properties, and number of disinfected fluid, the properties of the saturating gas properties destroy microorganisms, etc.

First option is the gas saturation is preferred for relatively small amounts of disinfected fluid, easier to operate, as it does not require high pressure, gas saturation, but requires a relatively large time of gas saturation.

In the first scenario, decontaminate liquid is placed in a closed tank, isolate it from the atmosphere, creates a pressure not less than 3 kg/cm2small bubbles under pressure, for at least 60 minutes is blown into the (bubbled) air into the liquid from the bottom of the tank (bottom), for example, through the collector saturation with holes, for example, 0.05 to 0.1 mm. Rising up small bubbles of air under pressure is dissolved in the disinfected fluid and saturate it to the equilibrium state (the principle of obtaining carbonated water). The higher the pressure in the vessel, the greater the amount of air dissolved in the disinfected fluid and intracellular fluid of microorganisms.

The amount of air dissolved in the disinfected fluid and intracellular fluid of microorganisms depends not t is like from pressure, but also on the temperature of the disinfected fluid and air. The lower the temperature, the greater the amount of air can be dissolved in the liquid. Fluid properties and saturating gas also affect gasanalysis - such as carbon dioxide dissolved in the liquid 33 times more and faster than air (nitrogen).

Rising above the norm (when bubbling the gas, i.e. the feed is constant in the capacity of the saturating gas pressure in a closed vessel, if necessary, release through the pressure relief valve capacity saturation.

The required quantity of gas saturation decontaminate liquid not only provide time and saturation pressure, but the magnitude of the volume flowing through the fluid saturating gas, which is calculated from the volume of saturated liquid.

The amount of pressure in a closed tank of gas saturation and the time decontaminate fluid under pressure in this tank is chosen experimentally from conditions to achieve the required gas saturating intracellular fluid microorganisms that ensure their destruction in the subsequent threshold decompression.

The values of the required quantities of the above indirect parameters of gas saturation determined experimentally when practicing the process of disinfection of a particular fluid is the capacity to destroy their specific microorganisms and provide them (with some margin) when the workflow execution disinfection liquids.

Experimental work, the authors determined that for assured destruction threshold decompression germs Staphylococcus on the outer surface of solid objects of their intracellular fluid is necessary to saturate the air to the equilibrium state when the external pressure is not lower than 3 kg/cm2in a period of time not less than 60 minutes at a temperature of not higher than 15°C.

When the external air pressure is less than 3 kg/cm2the effect of disinfection (killing microorganisms Staphylococcus) is present regardless of the time of exposure of the microorganisms under this pressure. The lack of effect of disinfection can be explained by the fact that the amount of air dissolved under these conditions in the fluid of the cell micro-organisms, is insufficient to rupture the membranes of their cells when a sudden release of pressure (low value threshold decompression).

The authors suggest that in the case of the use of carbon dioxide or its mixtures with air time decontaminate items under the pressure of gas saturation can be reduced to 2 minutes, while increasing the pressure further reduce it (up to 30 seconds when the pressure increases exposure to 10 kg/cm2).

To reduce the time required of gas saturation decontaminate liquid suitable mechanically stirred.

Optimalen the e values of the above parameters technology of gas saturation (pressure and time pressure), ensure gasanalysis and quality disinfection fluid decompression, determine in each case in relation to existing conditions, properties decontaminate liquids and applied saturating gases, permeability, and strength of the cells of micro-organisms present in disinfected liquids, etc. the Authors suggest that the above pressure and the dwell time under pressure for all microorganisms are approximately the same.

The magnitude of the volume of gas saturation, type of saturating gas, the value of its flow rate and injection pressure to decontaminate liquid, the amount of time and pressure of gas saturation decontaminate fluid and intracellular fluid are microorganisms appoint conditions obtain quantities of gas saturation of intracellular fluid of microorganisms present in disinfected liquid, the exposure time in the tank of gas saturation, ensure destruction of microorganisms subsequent threshold decompression on the bypass hole collector capacitance Ratnasiri.

The second option of gas saturation is preferred for relatively large volume of disinfected fluid, more difficult to operate, as it requires a high pressure of gas saturation, which reduces the time of gas saturation within the gunning liquid microorganisms.

In the second variant decontaminate liquid is saturated with air at the intake from the source, a feed pump and/or sanasana pipeline receiver, injection of air into the stream of moving decontaminate liquid, air is injected over the entire area of the stream at an angle to its direction of motion, small bubbles, for example, through the collector saturation with holes of 0.05 - 0.1 mm

Volume sensornogo pipeline receiver, the amount of flow and pressure flowing through him decontaminate liquid, type of saturating gas, the amount of flow and pressure appoint conditions for obtaining the desired value of the equilibrium gas saturating intracellular fluid of microorganisms present in disinfected fluid, during its transport from the source to the bypass hole collector capacitance Ratnasiri, ensure destruction of microorganisms threshold decompression on the bypass holes.

After the gas saturation decontaminate liquid sharply ratnasamy bypass through holes of the collector with a diameter of 0.5 to 1.5 mm from the tank saturated with excess pressure in the tank Ratnasiri without excess pressure (atmospheric pressure).

On the bypass holes (directly on them and after them) there is a sharp decrease of excess pressure in Odesa through them fluid, from which stands out sharply in the atmosphere dissolved air. At the same time from the intracellular fluid of microorganisms present in the liquid, also sharply distinguished dissolved air that remains inside the cell and initially stretches it, and then breaks at the weakest point (kills microorganism threshold decompression). Decontaminated thus the liquid flows into the open capacity Ratnasiri, which can simultaneously be capacity-store decontaminated fluid, and it is sent to the consumer.

It should be borne in mind that if the overflow drain pipe will be of large diameter (for example, 100 mm), in "thick" the stream flowing from it, the liquid may not be effective threshold decompression, therefore, may not be available and the quality of the decontamination fluid. Creating an effective threshold decompression is possible only in a relatively small stream flowing through the bypass hole liquid (with a diameter less than 1.5 mm), and even better in rasplyvayas stream, for example in tangentially swirling. To reduce the time decontamination of large amounts of fluid are used collector Ratnasiri having a large number of small holes, the total area of the bore which must be men is more of the cross-section area of the inlet pipeline (or in front of small holes will not be required excess pressure, they will not be required pressure drop and effective decompression).

To excessive pressure in a closed vessel saturation when the flow of fluid from her capacity Ratnasiri not decreased, in order from the intracellular fluid of microorganisms present in disinfected fluid ahead of time is not allocated dissolved gas), capacity saturation all the time served in the air volumetric flow rate not less than the volumetric flow of the liquid, return the fulfilled through hole collector capacitance Ratnasiri (for example, continue sparging air). In the absence of such accompanying charge capacity saturation part of the air from the intracellular fluid of the microorganisms will slowly be released in capacity saturation, and the remaining dissolved air may not be enough to rupture the cell threshold decompression with subsequent sharp her Ratnasiri on the bypass holes.

System sampling, decontamination, storage, liquid supply to the consumer periodically disinfected chemically active substances, for example chlorine, which periodically, for example once per day, intermittent inject into a disinfected or replacement fluid at the inlet to the pump, the feed decontaminate fluid from the source to install disinfection, and then to the consumer.

Known installation decontamination of solid objects decompression using chemically neutral gas, containing the camera saturation and Ratnasiri intracellular fluid of microorganisms present on the surface to be disinfected solid objects (patent No. 2045150 And 01 F 25/00).

A disadvantage of the known installation is that it can only disinfect the surface of solid objects, and for disinfecting liquids not applicable.

The closest analogue to the requested installation according to the purpose and aggregate similar essential features is the installation of disinfection fluid, comprising the device of gas saturation and Ratnasiri decontaminate fluid and intracellular fluid are microorganisms decompression (EN 2114791, 10.07.98, C 02 F 3/02).

The disadvantage is the lack of options and technologies saturation and Ratnasiri fluid, providing high-quality disinfection at optimum cost and time.

The purpose of the proposed installation is to eliminate these disadvantages, that is simpler and cheaper technology for decontamination fluid, reducing time and costs.

This objective is achieved in that the apparatus for disinfecting fluid containing device of gas saturation and Ratnasiri decontaminate fluid and intracellular fluid within it microorgani the MOU, the device of gas saturation is made of a sealed container of saturation, are equipped with a safety drain valve, manifold, gas saturation, evenly distributed in its lower part and having a hole diameter of 0.05-0.1 mm, the cavity of which is connected by tubing to a source of compressed gas through a controlled valve, and the device Ratnasiri made from the container communicates with the atmosphere and equipped with a collector Ratnasiri mounted in its upper part and having a hole diameter of 0.5-1.5 mm, the total area of the bore which is less than the cross-section area of the inlet pipeline, while the cavity of the collector Ratnasiri pipe connected to the lower part of a tank of gas saturation through a controlled valve.

The set of essential features of the proposed installation showing new properties, namely, that the disinfecting liquid to produce affordable gas (air), the quality of the decontamination provide specific technology parameters (pressure and time of saturation and Ratnasiri decontaminate liquid), specific characteristics of the elements of the installation (the diameter of the bypass hole, the size and characteristics of the units).

Thus, the set of essential features offered the first installation meets the criteria of "significant differences" and "novelty."

The proposed installation can be performed in two ways (depending on the capabilities and needs, local conditions, properties and quantity decontaminate liquids, properties of the used gas saturation), which is depicted in figure 1 and 2.

In both embodiments, the apparatus comprises a device 1 of gas saturation decontaminate fluid and the device 9 of its Ratnasiri. On the bottom of the container 13 of the device 1 of gas saturation of the first installation mounted manifold 2 of gas saturation, which is connected by a pipe 3 through the valve 4 source 5 saturating gas (e.g. air), the pipe 6 through the valve 7 and the pump 8 with a source of disinfected fluid (e.g., drinking water).

The device 9 Ratnasiri decontaminate liquid equally in the first and second embodiments of the installation. In the upper part of the vessel 20 device 9 Ratnasiri mounted collector 10 Ratnasiri is connected by a pipe 11 through the valve 12 with the lower part of a tank of gas saturation 1. The total area of the holes of the collector Ratnasiri 10 is less than the cross-section area of the pipe 11.

In the first variant of the design of the proposed installation (Figure 1) device 1 of gas saturation decontaminate fluid made in the form of container 13 excessive (high) pressure, equipped with a sensor 14 max the maximum level, sensor 15 minimum level, level 16 in her decontaminate liquid, and the upper part of the vessel 13 is connected to the source 5 compressed saturating gas (air) pipe 17 through the valve 18 (figure 2 position 13, 14, 15, 16, 17, 18 there are no useless). The volume of the vessel 13, the configuration and strength determine and designate in each case based on the capabilities and needs of the production and the design of the facility.

In the second variant of the design of the proposed installation (Figure 2) device 1 of gas saturation decontaminate liquid made of pipe receiver 19 without the above additional equipment (without level sensors 14 and 15, a sensor 16, without an additional source connection 5 compressed air pipe 17 through the valve 18). The volume of the pipeline receiver 19, the length, configuration, and strength determine and prescribe based on the capabilities and needs of the production and the design of the facility. However, the performance of the pump 8 must be greater consumption of disinfected fluid through the openings of the collector 10 Ratnasiri liquid.

Upornosti pump 8 and its volume flow designate and provide in each case based on the capabilities and needs of the production and the design of the facility.

The device 9 Ratnasiri of bessara jwaamoj fluid made in the form of the vessel 20 without excessive pressure, communicated with the atmosphere through maloperevalny drainage and pressure relief valve 21. Volume of tank 20, its configuration and strength determine and prescribe based on the capabilities and needs of the production and the design of the facility.

Capacity 13 and line receiver 19 is communicated with the atmosphere through the vent-relief valve 22 that are configured to the desired pressure equilibrium of gas saturation decontaminate fluid and intracellular fluid inside microorganisms.

Source 5 compressed saturating gas (air) in both versions of the device 1, the gas saturation can be connected by a pipe 23 to the inlet of the pump 8 through the valve 24 and pipe 25 to the outlet of the pump 8 through the valve 26.

The source 27 of reactive oxidant, such as chlorine, is connected by pipe 28 through a valve 29 to the inlet of the pump 8, and the pipe 30 through the valve 31 to the outlet of the pump 8.

The entrance to the device 1, the gas saturation is connected to the source of disinfected water from the pipe 32 through the valve 33 and the pump 8, and the output of the device 9 Ratnasiri connected with consumer decontaminated liquid pipe 34 through the valve 35 and the pump 36.

Decontamination fluid through the proposed decompression installation do the following.

In the initial position all valves installed in closed the m position. Open the valve 33 and 7 and decontaminate liquid through pipe 32 enters the device 1 of gas saturation. The pump 8 takes decontaminate fluid from a source increases its pressure to the desired level and delivers it through the pipe 6 through the open valve 7 in the first embodiment, the structure of the device 1 into the container 13 (Fig 1), in the second embodiment, the structure of the device 1 is in the pipeline receiver 19 (Figure 2).

In the first embodiment, the structure of the device 1, after filling capacity 13 decontaminate liquid on the signal of the level sensor 14 and/or by a visual inspection of the sensor 16 or simultaneously with the beginning of the filling capacity 13 open valve 4 and serves on line 3 saturating gas (e.g. air) from a source 5 into the reservoir of gas saturation 2. Through holes with a diameter of 0.05 to 0.15 reservoir 2 air enters decontaminate liquid barbthroat (rises through it up) and dissolved in it (Figure 1). The injected air (gas saturation) and served decontaminate the liquid in the tank 13 raises the pressure to the desired value.

At the signal of the level sensor 14 and/or by a visual inspection of the sensor 16 to close the valve 7 (switch off the pump 8, if there is no parallel Autonomous device 1 of gas saturation decontaminate liquid), cease to apply decontaminate liquid in the tank 13, and is saturated with the second gas (air) continue to serve in the capacity of 13 during the whole time of saturation of intracellular fluid of microorganisms, located in the disinfected fluid (e.g., for at least 60 minutes at a gauge pressure of not less than 3 kg/cm2).

In the second embodiment, the structure of the device 1 of gas saturation simultaneously with the beginning of the filling pipe receiver 19 decontaminate fluid to open the valve 4 and serves on line 3 saturating gas through line 6 from source 5 V collector saturation 2. Through holes with a diameter of 0.05 to 0.15 reservoir 2 saturating the gas is delivered to decontaminate the fluid enters the flow decontaminate liquid, partially barbthroat (rises) through it up and dissolved in it (Figure 2).

The volume and configuration of the container 13 and pipe receiver 19, the magnitude of the pressure of the mixture of the liquid with gas, a view of the saturating gas, the amount of time spent in them a mixture of liquids with gas, the flow rate and the total amount of injected saturating gas appoint conditions of dissolution in the intracellular fluid of microorganisms amount of gas that destroys the cells of the microorganism threshold decompression of subsequent bypass of gas-saturated liquid through the openings of the collector 10 Ratnasiri.

The value of the selected saturation pressure decontaminate liquid in the tank 13 and in the pipeline receiver 19 support (regulate) drainage-protection is animalname valves 22, which relieve excess pressure (gas saturation) in the atmosphere.

To reduce the time of gas saturation decontaminate liquid (in case of application of the first variant of the device 1 of gas saturation) open valves 24 and/or 26 and saturating the gas through pipelines, respectively, 23 and/or 25 of the source 5 serves, respectively, to the inlet of the pump 8 and/or on the output of the pump 8. In this case, using a pump 8 produce preliminary (optional) saturation decontaminate liquid gas (air) before its subsequent final consystem in the vessel 13.

After saturation of disinfected fluid and intracellular fluid of microorganisms required amount of gas through a certain amount of time, such as timer signal in the first embodiment of saturation (figure 1 not shown), open the valve 12 and decontaminate fluid through the pipeline 12 from the tank 13 (in the second variant without automation, without time exposure timer, pipeline receiver 19) enters the collector 10 Ratnasiri. After the gas-saturated liquid from the bypass hole of the collector 10 it is sharply reduced pressure, and from the intracellular fluid of microorganisms in contrast, dissolved gas, which is the threshold decompression destroys the cells of microorganisms.

When used for g is Considine decontaminate liquid of the first variant of the device 1 of gas saturation simultaneously with the opening of the valve 12 to open the valve 18 and saturating the gas (air) from the source 5 through the pipe 17 enters in the upper part of the container 13. Thus the volume flow of the gas in the tank 13 should not be less than the volumetric flow of gas-saturated liquid, extruding from the tank 13 through the bypass hole collector Ratnasiri 10 that allows you to maintain (not decrease) the pressure in the tank 13 when the flow of gas-saturated liquid from the tank 13 to the excessive pressure in the container 20 without excessive pressure.

After squeezing all the gas-saturated liquid from the tank 13 into the container 20, that is, the signal level sensor 15 and/or by a visual inspection of the sensor 16, close the valve 12 open valve 7 (if the pump 8 has been turned off, then turn it on)via the pipeline 6 into the container 13 from the source goes to the next gas saturation, a new portion to be disinfected liquid and the above cycle saturation - Ratnasiri repeats. The valves 24 and 26 while constantly open and saturating the gas continuously flows from the source 5 to the collector 12 of saturation (capacity 13).

When using the second variant of the device 1 of gas saturation decontaminate liquid saturation process - Ratnasiri produce constantly (continuously, without cycles) by providing the required gas saturation during the flow of fluid from the pump 8 through the pipeline receiver 19 to the collector of Ratnasiri 10 (due to time nahodeny the disinfected fluid in the pipe receiver 19). However, the performance of the pump 8 provides a greater flow rate through the collector Ratnasiri 10.

From collector 10 rasasastra and disinfected threshold decompression of the fluid (water) enters the tank 20 of the device 9 and the pipe 34 through the valve 35 and pump 36 are served to the consumer. So in the vessel 20 due to the influx of rasasastra and decontaminated liquid and gas flow of Ratnasiri was not raised pressure (if the volume flow decontaminated fluid to the consumer will be less than its volumetric flow), gas Ratnasiri release into the atmosphere through maloperevalny relief valve 21.

Periodically, for example once per day, the installation (system fence decontaminate fluid saturation and Ratnasiri, storage and delivery to the consumer) short handle (sterilized) chemically active substances, for example chlorine. For this preventive surgery without stopping the decompression process of decontamination fluid (if it's not food products, such as water or waste water), short-term, for example for a few minutes, open the valves 29 and 31 and the pipes 28 and 30 from a source 27 are injected into the pipeline 6 (before and/or after the pump 8) in the desired amount of chemically active substance (e.g., chlorine). This substance is dissolved in assaradevi fluid and transported to be disinfected (and then disinfected fluid on all systems installation and destroys microorganisms on the inner surface of the wall.

If decontaminate liquid is a food product, for the above preventive operations briefly stop the process decompression disinfection, replace the food liquid wash water in which the above-mentioned technology inject chemically active substance, and after the decontamination installation drained wash water and continue the process of decompression disinfection of food liquids.

To ensure the continuity of the process of decontamination fluid (continuous cycle saturation and cycle Ratnasiri fluid), and increasing the productivity of the installation may have multiple independent devices of gas saturation, connected in parallel with the source of disinfected fluid, a source of compressed gas saturation, the device Ratnasiri controlled independently through the valve.

The application of the proposed method and plant decontamination fluids will reduce the cost and time required for decontamination fluid, to improve the quality of disinfection, preserve the useful properties decontaminate liquids, improve the environment and safety during decontamination.
