The technical scheme that the utility model further limits is:
Preferably, be communicated with at the 5th water pipe and loop back water pipe, looping back water pipe is provided with and loops back water valve, this backwater design is in order to increase total inflow in running, the dense water circulating reflux of part is to ultrafiltration prime water tank, make milipore filter under the situation that full dose is filtered, enough current flushing membrane silks be arranged, reduce the dirty stifled situation of film silk.
Preferably, loop back water valve and be provided with the control circuit that is communicated with the PLC controller.
The beneficial effects of the utility model are: the utility model adopts the fully-automatic intelligent control model; the effectively stable operation of support equipment; pressure signal control reliably; guaranteed that every pressure is lower than rated value; effectively protected membrane module; prolonged the service life of membrane module; control cleaning frequency by pressure differential; saved the cleaning water yield greatly; increased system's aquifer yield; the reflux line that increases and quantity of circulating water make the milipore filter cleaning frequency prolong, and have increased that aquifer yield has been saved water for cleaning and medicine is washed cost.
