A DETAILED DESCRIPTION OF THE INVENTION
[0012] Next, I'll describe examples of the implementation of the present invention with reference to the accompanying drawings. System cleaning for major products, such as motor vehicle (hereinafter simply called "purification system"), in accordance with the example of the implementation is part of the process to clean the vehicle in a manner cleaning process as the previous one, for example, process color of the vehicle. Further details will be described the structure of this system cleaning. In this case a chemical solution in this example implementation is a water solution of (cleaning solution) reagent, in which the initial treatment reagent solution diluted specified number at a given degree of dilution.
[0013] cleaning System 1 is a system with a circulating a chemical solution, which cleanses the body 10 vehicle (one example of a major products, such as vehicle) before painting process through the use of a chemical solution is 20, which includes micro-bubbles, and in which a chemical solution 20 circulates so that it can be reused. Cleaning system 1 mainly includes the washing tub 2, device 3 tool 4 submission of microbubbles, medium 5 formation of surface flow, device 6 removal of carbon dioxide and tool 7 circulation, as shown in figure 1.
[0014] Rinsing bath 2, which is a chemical solution (20) cleaning products by his immersion in a chemical solution (20)includes a basic bath 2A and supporting bath 2b. The main bath 2A represents the big box bath with open upper part. When cleaning the housing 10 main bath 2A able to hold the specified number of chemical solution. That is the main bath 2A has such a volume, which fits a sufficient number of chemical solution to submerge the whole building 10.
[0015] Auxiliary 2b bath is a bath, which is less than the main baths 2A and is located adjacent to one edge of the main baths 2A in the longitudinal direction. This helper 2b bath is a bath, to hold the bubbles and chemical solution 20, flowing through the edge of the adjacent face of the main baths 2A.
[0016] device 3 separates the oil from the chemical solution is 20 by collecting bubbles rose to the surface of the chemical solution 20 in the main bath 2A rinse baths 2 in the process of cleaning block 10, as well as part of a chemical solution is 20 near the surface of a chemical solution is 20. That is device 3 is a device, which separates the oil from the chemical solution is 20 by collecting bubbles accumulated in the auxiliary tub 2b, and part of the chemical solution near the surface of the chemical solution 20 in the auxiliary tub 2b by ensuring their overflowing through the end part of the main baths 2A. 3 unit includes the main body device 3 and the heating medium 8. The main body of the device 3 contains three tanks: the first separation tank 3A, second separation tank 3b and third separation tank 3C, separated from each other walls at a given distance, and to hold (i.e. accumulation) chemical solution 20 and separating oil. The heating device 8 is used for heating the chemical solution 20 in the main building device 3. Below the walls 21, separating the first separation tank 3A and second separation tank 3b, opened, so that when the main building device 3 is a chemical solution 20, the latter may proceed through the gap below the walls 21 in the second separation tank 3b, adjacent to the first cut-off tank 3a. Also part below wall 22, separating the second separation tank 3b and third separation tank 3c, opened, so that when the main building device 3 is a chemical solution 20, last may flow through the gap below wall 22 in the third separation tank 3c, connecting with the second separation reservoir 3b.
[0017] First separation tank 3a reported with auxiliary bathroom 2b pipeline 11 through the pump 9 so that a chemical solution 20 and bubbles can be pumped from the zone near the surface of the chemical solution 20, located in the auxiliary tub 2b, in the first separator tank 3 through line 11 by actuation of the pump 9. Also, the pipeline 12, from funds 7 circulation, which will be described later, it communicates with the lower part of the first separation tank 3a (i.e. the lower part on one end of the main body device 3). This pipeline is a pipeline of 12 for filing a chemical solution is 20 from 7 circulation in the bottom part of the main body device 3. Submission of a chemical solution is 20 through a pipeline 12 facilitates the flow of the chemical solution 20 in the longitudinal direction of the main body device 3 (that is, in the direction of the dashed arrows in figure 1) in the bottom of the inside of the main body device 3.
[0018] Second separation tank 3b has a larger volume and also wider in the longitudinal direction of the main body device 3 than the first separation tank 3a and third separation tank 3c, connected with the second separation reservoir 3b through the partition wall 21 and 22. This second separation tank 3b is a reservoir used to collect bubbles (including oil, impurities etc), accumulated on the surface of the chemical solution 20, located in the adjacent first separation tank 3a, and through which is partitioning off the wall of 21, and also for storage of oil, which surfaced when a chemical solution 20 flows in the longitudinal direction of the main body device 3 (i.e. in the direction of the dashed arrows in figure 1).
[0020] the Heating medium 8 is a means for heating a chemical solution is 20, located in the main building device 3. A heating device 8 can be, for example, an electric heater. Heating of chemical solution 20, located in the main building device 3, heating means 8 to the specified temperature activates the rise of oil in a chemical solution 20 to the surface of a chemical solution is 20.
[0021] Thus, in device 3 is a chemical solution 20, carrying the inclusion of oils and impurities and that was moved out of the satellite baths 2b rinse baths 2, as well as chemical solution 20, served from 7 circulation. Chemical solution 20 in the bottom part of the main body device 3 slowly flows in the longitudinal direction of this case, the heated to the desired temperature heating means 8, and kept there for a certain period of time (30 minutes in this example, the implementation). At this time, the oil in a chemical solution 20 rises to the surface of a chemical solution is 20, and it rose oil destroys the accumulated here bubbles (in particular, the bubbles that have accumulated on the surface of the chemical solution 20 in the second separation tank 3b), and, as a result, the number of bottles decreases. That is device 3 is able to remove impurities in the wash tub 2 and bubbles, including oil, thus destroying the bubbles that have accumulated on the surface of the chemical solution 20, using oil, rising with separate oil and chemical solution is 20. Thus, device 3 separates the inclusion of oil, and impurities of a chemical solution is 20, displays separated inclusion oils and impurities from the system and returns the chemical solution 20, liberated from the oil, and impurities in the 7 circulation.
[0022] Tool 5 formation of surface flow is a tool for the formation of surface flow in a chemical solution 20 near the surface of a chemical solution is 20 to remove the bubbles rising to the surface chemical solution 20 in the main bath 2A rinse baths 2, with the surface of a chemical solution is 20. That is, the medium 5 formation of surface flow is the means of formation of surface flow in a chemical solution 20 near the surface of a chemical solution is 20 to remove air bubbles that accumulate on the surface of the chemical solution is 20, which was filled with the main bath 2A to clean the casing 10. Tool 5 formation of surface flow includes many pipelines 19 filing a chemical solution, which are rows in the transverse direction rinse baths 2 at one of its end in the longitudinal direction, as shown in figure 2. In addition, the 5 formation of surface flow is reported with the 7 circulation through the pipeline 15, so a chemical solution 20, supplied through the pipeline 15 may be made in each of these pipelines 19 submission of chemical solution, and the number (that is, the mass of the jet) chemical solution 20, supplied from each of the pipelines 19 submission of chemical solution into the master bath 2A rinse baths 2, can be adjusted individually. As a result of tool 5 formation of surface flow submits (i.e. delivers a) chemical solution 20 in the main bath 2A of each of the feed pipelines chemical solution 19 near the surface of a chemical solution is 20, which is in the main bath 2A, when regulating the mass of the jet flow supplied chemical solution is 20. Accordingly, the surface current can be formed so that a chemical solution 20 runs in the direction of the auxiliary baths 2b, and you can properly adjust the structure of the surface flow (i.e. flow). In this example, the implementation of the chemical solution 20, served from pipelines 19 submission of chemical solution, is served so that the mass of the jet chemical solution 20 increases (i.e. consumption of the chemical solution increases 20) from the Central part out in the transverse direction rinse baths 2, as shown in figure 2, and structure of the surface flow is defined to facilitate within bubbles near the surfaces with 2 side walls and corners on the side of assets 5 formation of surface flow in the main bath 2A, where the bubbles tend to accumulate. In this regard, in this example, the implementation of the chemical solution 20, served in the pipelines 19 submission of chemical solution, is served from 7 circulation, but the invention especially not restricted to this example. In another case, a chemical solution 20 can be made directly through a pipeline from the specified location in the main bath 2A rinse baths 2 (for example, the bottom of the main baths 2A).
[0023] Tool 4 filing is a means of filing a chemical solution is 20, which includes micro-bubbles, in the main bath 2A rinse baths 2 and includes the unit 4A of formation of micro bubbles, which is a means of formation of micro-bubbles and the pipeline 4b filing of microbubbles, which is a branched pipeline, which is connected to the device 4A formation of micro bubbles. In addition, the unit 4A of formation of micro bubbles communicates with the device of air supply (not shown) through the device 6 removal of carbon dioxide. One end of the pipeline 4b filing microbubbles reported with one end of the device 4A formation of micro bubbles. Other end of the pipeline 4b filing microbubbles branches into many drainage pipes, as shown in figure 1. These discharge pipes are lots of places on the inner surface of the main baths 2A. End part of each of these branch pipe is a channel 4C filing of microbubbles, intended for the supply of micro bubbles.
[0024] These channels 4C filing microbubbles densely located on the inner surface of the main baths 2A near a zone where building 10 loaded (i.e. included) in a chemical solution 20 in the main bath 2A rinse baths 2, and serves a chemical solution 20, including micro-bubbles, served device 4 submission of microbubbles. That is, building 10 transported into the mud bath 2 carrier vehicle (not shown) so that he sank in a chemical solution 20 in the main bath 2A rinse baths 2, as shown in figure 1. Channels 4C filing microbubbles densely located on the inner surface of the main baths 2A, which faces the rear of the chassis 10, as well as on the inner surfaces of the walls of the main baths 2A, who turned to the left and right sides of 10 when it is immersed in a chemical solution 20. That is, channels 4C filing microbubbles densely located on the inner surface of the washing baths 2 near a zone where building 10 immersed in a chemical solution 20, located in a wash tub 2. Thus, the 4 submission of microbubbles may file a chemical solution 20, including micro-bubbles, channel 4 with the filing of microbubbles, using a chemical solution 20, served from 7 circulation, which will be described below, and the air supplied from the air supply. In particular, when the front part of the hull 10 immersed in a chemical solution 20 (that is, when the body of 10 is included into the bath and, consequently, in a chemical solution 20 in the main bath 2A), chemical solution 20, including micro-bubbles in high concentrations, can be served to the chassis 10 channel 4C filing microbubbles.
[0025] Device 6 removal of carbon dioxide is used for removal of carbon dioxide from the air used for the formation of micro bubbles device 4A formation of micro bubbles and equipment 4 submission of microbubbles. As a device 6 removal of carbon dioxide can be used, for example, a device designed to remove carbon dioxide through the submission of air in alkaline solution to remove carbon dioxide and lead to the emergence of bubbles.
[0026] Tool 7 circulation is a means of circulating the chemical solution is 20 by the return of chemical solution 20, of which with the help of the device 3 separate oil was allocated to the oil, again in the main bath 2A rinse baths 2. Tool 7 circulation pipeline includes 16 connecting the lower part of the auxiliary baths 2b with the end part of the suction side of the device 4A of the formation of the micro-bubbles and pump 17 and heat exchanger 18, mounted in a pipeline 16. In addition, device 3 reported on the bypass scheme on the intake side of the pump 17 with the pipeline 16 through line 12 and line 14, so a chemical solution 20, from which device 3 deleted oil is returned to the tool 7 circulation, as described above. Heat exchanger 18 is able to heat a chemical solution 20 flowing through the pipeline 16, up to the set temperature. Thus, the 7 circulation can circulate chemical solution 20 by actuation of the pump 17 for pumping chemical solution is 20, which is in additional tub 2b, and chemical solution 20, from which device 3 deleted oil, in unit 4A of formation of micro bubbles when heating a chemical solution is 20 in the heat exchanger 18. And the heat exchanger 18 is required only in case, when circulating a chemical solution 20 it is necessary to heat.
[0027] Next we will describe the process of cleaning to clean the casing 10 using cleaning systems 1, the structure of which is described above.
[0029] in addition, in the process of cleaning the hull 10 bubbles, including oil and impurities and accumulated on the surface of the chemical solution 20, located in the main bath 2A, flow from the tail part of the main baths 2A satellite bath 2b by putting in action 5 of the formation of surface flow. Then when you remove the bubbles that accumulate on the surface of the chemical solution 20 in the main bath 2A, medium 5 formation of surface flow may file a chemical solution 20 so that consumption increases from the Central part out in the transverse direction rinse baths 2, as shown in figure 2. Regulation of surface flow in such a way by means of formation of surface flow 5 makes it possible to make the bubbles, which accumulate near the surfaces with 2 lateral walls of the main baths 2A, and bubbles, which accumulate in the corners of the main baths 2A with by 5 formation of surface flow, actively to flow in the direction of the minor baths 2b, which reduces the number of accumulated bubbles.
[0030] Next bubbles, gathered in the auxiliary tub 2b as a result of overflow from the main bath 2A, accumulate on the surface of the chemical solution 20 in the auxiliary tub 2b. Therefore, these bubbles is pumped pump 9 together with a part of the chemical solution 20, that is near the surface of the chemical solution 20, in the direction of the first separation tank 3A device 3. Chemical solution 20, of auxiliary baths 2b, is device 3 for a specified period of time and in the same time is heated, so that the oil in a chemical solution 20 rises to the surface of a chemical solution is 20. Besides, bubbles, accumulated at a chemical solution 20, located in the first separation tank 3a, shimmer in the second separation tank 3b. In the second separation tank 3b oil rises as a result of a chemical solution 20 is in it for a specified period of time, and this oil is combined with bubbles, accumulated on the surface of the chemical solution 20 (when rose oil is combined with the backlog of bubbles, the number of backlog of bubbles reduced as a result of effect of oil). Then bubbles, including oil and impurities and accumulated in the second separation tank 3b, gleams in the upper reservoir 24 third of the separation tank 3c, and bubbles including oil and impurities and accumulated in the upper reservoir 24, removed from the system through a pipeline 13.
[0031] additionally, the 7 circulation circulate a chemical solution is 20 by actuation of the pump 17 to pumping chemical solution 20 at the bottom of the auxiliary baths 2b, and chemical solution 20, from which removed oil device 3, in unit 4A of formation of micro bubbles when heating a chemical solution is 20 heat exchanger 18 to the desired temperature. In the device 4A formation of micro bubbles chemical solution 20, including micro-bubbles, a chemical solution is adjusted 20, pump 17, and the air from which the device 6 removal of carbon dioxide removed carbon dioxide, and is then served from a multitude of channels 4C filing of microbubbles in the direction of the loaded block 10.
[0032] multiple devices 4A formation of micro bubbles densely located on the inner surface of the main baths 2A near a zone where building 10 immersed (i.e. he enters in at the specified tub chemical solution 20, when building 10 reduced from over a main EN 2A rinse baths 2 (i.e., near the entrance to the bath, where housing 10 becomes immersed in the main bath 2A). As a result, when building 10 immersed in a chemical solution 20, micro-bubbles in high concentrations can be entered in a chemical solution 20, who were the first to swell in such part of the hull structure 10 that is difficult to penetrate chemical solution 20, thus, may increase the effectiveness of cleaning parts that are hard to penetrate chemical solution 20. In particular, there are many sections of the hull construction, 10, having the form of pockets and which are the parts of the body 10, where difficult to penetrate chemical solution 20. If a chemical solution 20 fills in these places, then during the cleaning process he almost never changes. Therefore, tightly spaced channels 4C filing microbubbles at the entrance to the bath, as described in this example implementation, provide an opportunity to introduce micro-bubbles in high concentrations in chemical solution 20, which initially can flow into such a construction in the form of pockets, thus ensuring higher efficiency of cleaning parts. As described above, cleaning system 1 in accordance with this example of the implementation of improved efficiency of cleaning block 10 by adding microbubbles. In addition, using the specified funds 7 circulation can circulate chemical solution 20 and reuse it.
[0033] Graph of figure 3 shows the change in treatment efficiency (in parts of the structure, having the form of pocket) in accordance with the difference in the content of oil and the difference in the number of micro bubbles (MP), supplied in the system of cleaning 1. In this graph, the horizontal axis oil content [], while the vertical axis purification efficiency: from bad to good. More curves in figure 3 reflects the cases in which the number of complaints of micro bubbles (ie the number of bubbles), from the bottom, increases. As shown an upward arrow in figure 3, when the number of complaints of micro bubbles increases, the effectiveness of treatment in parts of the hull construction, 10, having the form of pockets and in which chemical solution 20 difficult to penetrate, increases. In addition, as follows from figure 3, cleaning efficiency decreases when the oil content increases. However, when the number of complaints of micro bubbles increases, you can obtain adequate treatment efficiency even at the high content of oil. Thus, confirmed that the penetration of chemical solution 20, including micro-bubbles in high concentration in parts of the construction block 10, having a form of pocket, that is, in part, in which a chemical solution is difficult to break, when the body of the 10 immersed in a chemical solution 20, useful from the point of view of the efficiency of treatment.
[0034] Next graph in figure 4 shows the change of pH in accordance with the presence or absence of carbon dioxide. The shown results were obtained under the testing when the device 4A formation of micro bubbles supposed presence of a mixture of air and chemical solution 20. The change of pH was measured in time for the case when in a chemical solution 20 fed the normal composition of air under normal conditions, as it is done in analog, and in case of a chemical solution was 20 air, from which you removed carbon dioxide. In this graph, the horizontal axis represents time [h], and the vertical pH values. Figure 4 line connecting the solid black diamonds displayed on the graph, is the case with the air, which was removed carbon dioxide, and the line connecting the solid black squares are displayed on the graph, is the case with normal air under normal conditions. As follows from figure 4, with normal air under normal conditions, including carbon dioxide, pH decreased over time. This is due to the fact that a chemical solution 20, i.e. alkali, stops oxidation. From these results it is obvious that the removal of carbon dioxide from the air into the unit 4A of formation of micro bubbles, as is done in this example, the implementation, can prevent the change of pH in a chemical solution, which is in the main bath 2A, and thus ensures the maintenance of efficiency of purification of chemical solution 20.
[0035] Next graph in figure 5 shows the change in the efficiency of cleaning in accordance with the reagent dilution adding microbubbles. In this graph, the horizontal axis is the dilution factor of the initial solution, while the vertical axis of cleaning efficiency. Figure 4 curve, connecting solid black diamonds displayed on the graph, and the specified an arrow A, is a case in which were submitted by micro-bubbles, and the curve connecting solid black triangles shown on the graph, and the arrow, is a case in which micro-bubbles were not submitted. In this graph, the effectiveness of the cleaning can be sufficiently guaranteed, even if the cleaning agent diluted, due to increase of efficiency of purification by adding a micro bubbles, as is clear when comparing the difference between the case when the micro-bubbles added, and the case, when the micro-bubbles are not added. In addition, when the cleaning system 1 in accordance with this example of the implementation of the air supplied in unit 4A of the formation of the micro-bubbles of carbon dioxide removed, so even if a chemical solution 20 continues to circulate and re-used, pH, chemical solution 20 will not change, therefore can support the efficiency of cleaning chemical solution 20. In result, you can continue to provide adequate treatment efficiency even when chemical solution, i.e. the chemical solution with high dilution factor.
