Also have in the known technology by in feedwater, adding the film purging method on the mode flushing membrane surface of gas, but since gas at the filter interior skewness, developing result is not good.
Summary of the invention
The technical problem that needs a large amount of energy of dense water-circulating pump consumption in the utility model will solve in the prior art during pressure-pipe type membrane filtration high density pollution water, a kind of inner pressed hollow-fibre membrane or capillary-pipe film filter or tubular membrane filter that has comprised aerator is provided, and the gas that utilizes aerator to provide washes away the gentle liquid flow of proposing generation to the formation of film surface and avoids the film surface contamination.
Aerated filter of inner squeezed film of the present utility model comprises many hollow-fibre membranes or capillary-pipe film or tubular membrane, and two are drawn sap cavity, a shell and an aerator.Filter is vertically placed.Wherein hollow-fibre membrane or capillary-pipe film or tubular membrane top are drawn sap cavity with the top and are cast in, hollow-fibre membrane or capillary-pipe film or tubular membrane bottom are drawn sap cavity with the bottom and are cast in, hollow-fibre membrane or capillary-pipe film or tubular membrane inner chamber and bottom are drawn sap cavity and top and are drawn sap cavity and be communicated with, the chamber that draws water, bottom communicates with the filter feed pipe, and the chamber that draws water, top is provided with the dope drain pipe; Filtered fluid enters the filter inner chamber by membranous wall under pressure, flows out by many blank pipes that are arranged on the filter radial center or the water producing pipe that is arranged on the shell again.Aerator is arranged on filter bottom, washes away for the film surface provides body fluid to flow by continuous or intermittent aerating.
Technical characterictic of the present utility model is to draw bottom interior press mold filter housing and is provided with aerator in the sap cavity, and continuous or interruption aeration is realized washing away to the film surface.
Technical characterictic of the present utility model is that also described aerator can be at least one aeration head.

The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model aerated filter of inner squeezed film 100 comprises many hollow-fibre membranes or capillary-pipe film or tubular membrane 110, and two are drawn sap cavity 120 and 160, one shells 150 and an aerator 210 up and down.The bottom 111 and the top 112 of every hollow-fibre membrane or capillary-pipe film or tubular membrane 110 are openings, with film filter up and down two draw sap cavity 120 and 160 and communicate.The bottom 111 of every hollow-fibre membrane or capillary-pipe film or tubular membrane 110 and top 112 are cast in by potting resin 140 with the two ends of shell 150.Shell 150 by clip 190 with draw sap cavity up and down and be connected.Aerator be positioned at draw down more than 160 hollow-fibre membrane of sap cavity or capillary-pipe film or tubular membrane 110 under.On draw sap cavity 120 walls and be provided with at least one dope drain pipe 121.Under draw sap cavity and be provided with at least one feed tube 161 and at least one air inlet pipe 162, air inlet pipe 162 is communicated with aerator 210.Filtered fluid production fluid pipe 171 is arranged on the shell 150.
Be filtered liquid during use and entered by inlet 161, liquid sees through the film surface and enters in the film filter chamber under pressure, by production fluid pipe 171 outputs, dope and expose to the sun into gas flow out by dense water out 121.The film surface can also produce the gas disturbance on film surface by aerator 210 aerations except that the moving disturbance of concentrated stream.Gas and dope almost do not have the dead angle in upwards flowing.
Described aerator is at least one aeration head.
Fig. 3 is to second kind of aerated filter of inner squeezed film 200 of the utility model shown in Figure 4, its essential structure is identical with the essential structure of first kind of aerated filter of inner squeezed film 100 of the utility model illustrated in figures 1 and 2, identical part is represented with identical label, and no longer is repeated in this description.
Fig. 3 and second kind of aerated filter of inner squeezed film of the utility model shown in Figure 4 200 are with the difference of first kind of aerated filter of inner squeezed film 100 of the utility model illustrated in figures 1 and 2, filtered fluid production fluid pipe 310 is arranged on the filter radial center, and this filtered fluid production fluid pipe is provided with a plurality of holes 311 between the pouring layer up and down at filter.Filtered fluid production fluid pipe 310 is on the longitudinal centre line that draws sap cavity 120, and its top end opening stretches out from the roof that draws sap cavity 120 sealing, and its bottom sealing is cast in hollow-fibre membrane or capillary-pipe film or tubular membrane 110 bottoms.
