Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1, the efficient self-cleaning film separating purifying device of the utility model comprises feeder channel 1, circulating pump 4, cyclone 15, membrane module 2 and Rinsing Area 3; The outlet of feeder channel 1 is connected through feeder sleeve 5 with the import of circulating pump 4; The outlet of circulating pump 4 links to each other with the water inlet of cyclone 15, and the delivery port of cyclone 15 is connected through water inlet pipe 12 with the import of membrane module 2, and the import and export of membrane module 2 are connected through penetrating fluid carrier pipe 7 with Rinsing Area 3; Said feeder sleeve 5 is provided with inlet valve 9; Water inlet pipe 12 is provided with water intaking valve 10, is provided with dope carrier pipe 6 between the outlet of membrane module 2 and the feeder sleeve 5, and the junction of dope carrier pipe 6 and feeder sleeve 5 is between inlet valve 9 and circulating pump 4; Dope carrier pipe 6 is provided with dense water valve 11; Be connected with dope adjustable pipe 17 on the dope carrier pipe 6, two junctions of dope adjustable pipe 17 and dope carrier pipe 6 are positioned at the two ends of dense water valve 11, and dope adjustable pipe 17 is provided with manual pressure regulating valve 16; Be connected with blow-off pipe 8 on the discharge outlet of cyclone, blow-off pipe 8 is provided with draining valve 14.
Below be the course of work of the utility model:
Membrane module 2 adopts the cross-flow working method, and during operate as normal, draining valve 14 cuts out; Manual pressure regulating valve 16 parts are opened, and start circulating pump 4, and former water is passed through feeder sleeve 5, got in the cyclones 15 through circulating pump 4 by feeder channel 1; Get in the membrane module 2 through water inlet pipe 12, the clear water that filters out through membrane module 2 flows into Rinsing Area 3 from penetrating fluid carrier pipe 7 again, and condensed water is then passed through pressure regulator valve 16 along dope adjustable pipe 17 again; Import in the feeder sleeve 5, carry out next one circulation.Behind the operation certain hour; Close inlet valve 9 and water intaking valve 10, open dense water valve 11 and draining valve 14, membrane module 2 is carried out the negative pressure backwash; Clear water in the Rinsing Area 3 is recycled pump 4 through penetrating fluid carrier pipe 7; Suck membrane module 2, get into cyclone 15 through dope carrier pipe 6 and dope adjustable pipe 17 then, discharge through blow-off pipe 8 and draining valve 14.Membrane module 2 is a milipore filter, and in backwash process, the pressure in the membrane module 2 descends; Form " negative pressure ", under the effect of inside and outside differential pressure, clear water is reverse to be extravasated in the membrane module 2 from membrane module 2; Negative pressure acts directly on the face that needs to clean; Under the double action of clear water and negative pressure, impurity such as the big molecule solute of obstruction fenestra, bacterium secretion are taken out of fenestra, and destroy gel layer even the inorganic salt crust layer that adheres at the film pipe internal surface like this; Thereby recover the flux of film, guarantee that the film system keeps disposal ability efficiently.
The utility model in use; Select working time and backwash time according to the concentration of feed liquid, different with existing film cross-flow isolation technics is: it is its working flux that existing cross-flow isolation technics is selected at the flux that film formed behind the stable cake layer, and the working flux of the utility model is selected at the flux under the film surface cleaning state; Thereby the flux of the utility model will be much larger than the former (wanting high by about 30%) usually; Because the effect that controlling diaphragm is clean is excellent, can significantly improve the system works pressure of film, reduce the film surface velocity of fluid; Significantly improve the flux of film, thereby reach purpose of energy saving.
