Wherein: 1. clean water tank, 2. heating rod, 3. scavenging pump, 4. cleaning filter, 5. dissolving, 6. connecting line, 7. reverse osmosis membrane container, 8. concentrate recirculation pipe, 9. produce water return duct, 10. cleaning fluid mixing tube, F1, F2, F3, F4, F5, F6 are valve.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
As shown in Figure 1, the utility model blocks up problem in order to the dirt solving counter-infiltration, provide a kind of washing unit with reverse osmosis membrane of gas-liquid mixed, comprise the cleaning water tank 1, scavenging pump 3, cleaning filter 4, dissolving 5 and the reverse osmosis membrane container 7 that are connected by connecting line 6 successively;
In described reverse osmosis membrane container 7, be provided with reverse osmosis membrane, described reverse osmosis membrane container 7 is connected with cleaning water tank 1 with concentrate recirculation pipe 8 by valve F1 successively, and described reverse osmosis membrane container 7 is connected with cleaning water tank 1 by producing water return duct 9.
In the utility model, described valve F1 can select non-return valve, prevents concentrate recirculation, can all arrange Pressure gauge with the force value of Real Time Observation corresponding component on clarified water pump 3, dissolving 5, reverse osmosis membrane container 7 simultaneously.
The utility model device needs cleaning water tank 1, scavenging pump 3, cleaning filter 4, dissolving 5 and reverse osmosis membrane container 7 to be together in series successively with connecting line 6 before using, and connects scavenging pump 3 power supply, by compressed air access dissolving 5 clean for nothing oil.
First need the preparation before running, in cleaning water tank 1, filling counter-infiltration need produce water normally, then add medicament according to the concentration of cleaning formulation, be mixed with cleaning agent solution.When not needing filling counter-infiltration to produce water normally in cleaning water tank 1, stop counter-infiltration system, and switch valve, the feed pipe of incision purging system, dense water return pipe 8, product water return pipe 9, check whether normally each valve, and guarantee that power supply is connected.
Run purging system, first open scavenging pump 3, the cleaning fluid prepared in cleaning water tank 1 is sent into cleaning filter 4, send in dissolving 5 after 10 μm of filter element filterings, open without oily clean compressed air simultaneously, gas is mixed with cleaning fluid in dissolving 5, when pressure in dissolving 5 reaches optimal mixed effect, (namely gas fully mixes with cleaning fluid, after abundant mixing, gas is existing microgranular), gas and liquid mixture is sent in reverse osmosis membrane container 7.Because reverse osmosis membrane is that rolling meets film, so there is narrow runner between diaphragm and diaphragm, after gas and liquid mixture enters runner, minute gas is under pressure extruding, produces collision at membrane surface, thus makes diaphragm produce vibration.
The pollutant of general reverse osmosis membrane is also attached to the membrane surface on runner both sides, therefore because the vibration of diaphragm causes the pollutant adhered to produce be full of cracks and produce with film surface being separated and floating, and then carry out reacting and decomposing with the active ingredient of cleaning fluid, particulate matter after decomposition is back to by concentrate recirculation pipe 8 and product water return duct 9 and cleans in water tank 1 together with the gas and liquid mixture of band pressure, after pressurizeed by scavenging pump 3 again and send in cleaning filter 4, form wash cycles loop.
By the wash cycles of certain hour, observe the cleaning fluid color in cleaning water tank 1, and observe the change of scavenging pump 3 outlet pressure, after having waited until predetermined scavenging period, stop purging system.Respectively purging system and counter-infiltration system are rinsed with clear water, until PH becomes neutral simultaneously.Rear startup counter-infiltration system, adjustment pressure, flow etc., observe and produce discharge, produce water conductivity and reverse osmosis membrane pressure differential, contrast with the data before cleaning.
