Detailed description of the invention
As Figure 1-4, clean device to include cleaning water tank 1, flushing water pump 2, cleaning cartridge filter 3, by pipeline, the entrance of flushing water pump water intake ball valve 19 with flushing water pump 2 is connected, use pipeline to be connected with the outlet of flushing water pump 2 by flushing water pump water outlet ball valve 20, use pipeline that flushing water pump goes out Water Check Valve 21 and be connected with flushing water pump water outlet ball valve 20.Cleaning cartridge filter 3 pumps out Water Check Valve 21 and is connected with wash water.Flushing water pump water intake ball valve 19 is connected with cleaning water tank 1.
The one end cleaning feed liquor effusion meter 17 is connected with cleaning cartridge filter 3, and the other end and the one section of Chemical cleaning liquid feed valve 13 that clean feed liquor effusion meter 17 connect.One section of Chemical cleaning liquid feed valve 13 is connected with one section of membrane component water inlet pipe 12 of reverse osmosis unit by one section of Chemical cleaning feed tube 4.The water inlet pipe 9 that two-segment film element is entered with one section of membrane component water outlet in one end of one section of Chemical cleaning liquid back pipe 5 is connected, and the other end and one section of cleanout fluid return valve 14 connect.One end of one section of cleanout fluid return flow meter 18 is connected by pipeline and one section of cleanout fluid return valve 14, and the other end is connected with the arrival end cleaning back liquid house steward 8.
One end that liquid valve 16 is cleaned back with dense water side in one end of dense water side Chemical cleaning liquid back pipe 7 is connected, and the other end of dense water side Chemical cleaning liquid back pipe 7 is connected with the arrival end cleaning back liquid house steward 8, and dense water side is cleaned back the other end of liquid valve 16 and is connected with dense supply mains 10.One end that liquid valve 15 is cleaned back with product water side in the one end producing water side Chemical cleaning liquid back pipe 6 is connected, and the other end producing water side Chemical cleaning liquid back pipe 6 is connected with the arrival end cleaning back liquid house steward 8, and product water side is cleaned back the other end of liquid valve 15 and is connected with producing supply mains 11.The port of export cleaning back liquid house steward 8 is connected with cleaning water tank 1.
Work process described below:
After reverse osmosis unit runs a period of time, it should the transmembrane pressure of Timing measurement every section membranous system, when transmembrane pressure reaches 2 ~ 3kg, then need reverse osmosis membrane is carried out Chemical cleaning.Process below in conjunction with Chemical cleaning is described as a example by the cleaning step of the one-level two-part counter-infiltration system (system design is equipped with 8 cun of films 9, three cores dress putaminas 3, and a section is 2:1 with the putamina arrangement ratio of two-stage nitration) of routine:
The first step: open the flushing water pump water intake ball valve 19 of flushing water pump 2, flushing water pump water outlet ball valve 20, flushing water pump go out Water Check Valve 21, liquid valve 15 is cleaned back in water side, 16, one section of Chemical cleaning liquid feed valve 13 of liquid valve is cleaned back in dense water side to open product, open one section of cleanout fluid return valve 14, then start flushing water pump 2.The cleanout fluid cleaned in water tank 1 carries out Chemical cleaning by entering one section of membrane component water inlet pipe 12 after over cleaning cartridge filter 3 according to the cleaning flow of system design after flushing water pump 2 supercharging, in the process, the cleaning fluid volume entering reverse osmosis unit main frame then can show by cleaning feed liquor effusion meter 17 table.
Second step: after cleanout fluid is full of one section of membrane component of reverse osmosis, the opening degree of one section of cleanout fluid return valve 14 of regulation, making one section of flow value shown by flow value that is one section cleanout fluid return flow meter 18 being back to clean water tank 1 is the difference that one section of membrane component of reverse osmosis cleans feed liquor flow design value and reverse osmosis two-stage nitration cleaning feed liquor flow design value.By regulating the opening degree of one section of cleanout fluid return valve 14, the water yield that one section is cleaned back liquid is shunted, a part is by one section of Chemical cleaning liquid back pipe 5 to cleaning water tank 1, and another part then enters and is back to after proceeding Chemical cleaning in two-segment film element clean water tank 1 again.When cleaning two-segment film element, the cleaning of two-segment film element is returned liquid and will be refluxed from dense water side Chemical cleaning liquid back pipe 7 and product water side Chemical cleaning liquid back pipe 6 respectively when backflow.For example according to above-mentioned 2:1 membranous system, this set reverse osmosis unit is when carrying out Chemical cleaning, and one section of cleaning feed liquor flow of design is 16m3/ h(every putamina is 8m3/ h), when cleanout fluid is full of one section of membrane component, the most then need to regulate one section of cleanout fluid return valve 14 while observing one section of cleanout fluid return flow meter 18 flow value, the flow value regulating one section of cleanout fluid return flow meter 18 is shown as 8m3About/h, the cleaning fluid volume the most now entering two-segment film element is then remaining 8m3About/h, meets the water yield load that single membrane component of two-stage nitration can bear, and decreases the big flow cleaning liquid percussion to two-segment film element, makes the operation that purging system is more stable.
3rd step: according to the operating procedure of first two steps, the cleanout fluid of dense water side Chemical cleaning liquid back pipe 7, product water side Chemical cleaning liquid back pipe 6 and one section of Chemical cleaning liquid back pipe 5 will meet at after cleaning back liquid house steward 8 and be back to clean water tank 1, and cleanout fluid enters one section of membrane component water inlet pipe 12 of reverse osmosis through flushing water pump 2 again and is circulated cleaning.
The above only to preferred embodiment of the present utility model, is not limited to this utility model, and for a person skilled in the art, this utility model can have various modifications and variations.Every in the range of claim of the present utility model limits, any modification, equivalent substitution and improvement etc. done, all should be within protection domain of the present utility model.
