Abstract
The utility model relates to an on-line back kick device for inorganic membrane separation, particularly the on-line back kick device for inorganic film separation which can weaken or eliminate membrane pollution. The utility model is characterized in that a back flushing device is composed of a back flushing tank and an air bag or a membrane, and the back flushing tank is used for storing back flushing liquid. Before the commencement of back flushing, under the action of static pressure difference of filtered clear liquid, the air bag or the membrane is extruded to make the air bag or the membrane generate shape changes towards the upper part of the back flushing tank. The back flushing liquid is filled in the back flushing tank. When the back flushing begins, the air bag or the membrane is expanded under the instantaneous action of gas and the air bag or the membrane is pushed towards the lower part of the back flushing tank to move. Consequently, the back flushing liquid is pushed and passes through a membrane hole from the infiltration side of an inner membrane pipe of an inorganic membrane separator to rush at the inner side of the membrane. Thereby, pollutants remaining on the inner side of the membrane can be flushed out to eliminate the membrane pollution. The upper part of the back flushing device is provided with an electromagnetic valve which is used for controlling the gas to enter the air bag or the membrane and the electromagnetic valve also has the action of exhausting the gas.
Description
Technical field
The utility model relates to inoranic membrane and separates online backflushing equipment, refers in particular to the inoranic membrane that can weaken or eliminate the film pollution and separates online recoiling device.
Background technology
The inoranic membrane technology is that development in recent years is filtered and isolation technics faster, and at Separation of Solid and Liquid, liquid liquid separation field, it has tentatively replaced the tradition of part and has separated and filtering technique.The inoranic membrane technology plays an important role in fields such as food, medicine, chemical industry, oil and environmental protection, becomes the core technology of accurate separation technology field.During inorganic membrane filtration, owing to hold back particle in the film surface detention, thus gather, cause permeation flux to reduce.Inorganic membrane filtration belongs to cross-flow filtration, and cross-flow filtration helps to slow down film and blocks, but can not make its cancellation, and online backflushing is washed and then can be helped to eliminate the particle that is deposited on the film surface, permeation flux is descended reduce to minimum.Backwash is to adopt the method that applies counter-pressure in the per-meate side of film, a small amount of penetrating fluid is advanced to the purpose that reaches flushing in the feed liquid of film pipe inboard through carrier.General online backflushing device is by forming with the lower part: backwash fluid reservoir, compression gas tank, fluid infusion pump, pipe fitting valve and control valve.This mode is the direct backflush liquid of gas, and there is following shortcoming in this backwash mode: complex structure; Granule foreign in the gas enters in the counter-flushing liquid, and its is understood from reverse obstruction fenestra, thereby weakens backwash effect.Gas is partly dissolved in the aqueous solution, might form bubble, and bubble produces tension force on the film surface, forms the sealing gland on fenestra surface, and the blocking portion fenestra weakens backwash effect.
Summary of the invention
The purpose of this utility model is improved at shortcoming that exists in the background technology and problem, provides a kind of simple in structure, counter-flushing liquid cleaning, the effective inoranic membrane of backwash effect to separate online recoiling device.
Technical solution of the present utility model is: the utility model comprises the inoranic membrane separator, back flushing device, the control valve group, in the inoranic membrane separator inorganic film tube is housed, the inoranic membrane separator is provided with the material liquid import, the trapped fluid outlet, filter back purified liquor outlet and counter-flushing liquid inlet, filter the back purified liquor outlet and be provided with magnetic valve, when backwash, close, backwash is opened after finishing, the counter-flushing liquid inlet links to each other with back flushing device, be characterized in that back flushing device is made up of the recoil gentle capsule of cleaning of evaporator or barrier film, the recoil cleaning of evaporator is used for storing backwash liquid, before backwash begins, cross cleaner liquid under the differential static pressure effect, extruding gasbag or barrier film, make air bag or barrier film to the top deformation of recoil cleaning of evaporator, be full of backwash liquid in the recoil cleaning of evaporator, backwash begins air bag or barrier film expands under the momentary action of gas, promote air bag or barrier film to the bottom motion of recoil cleaning of evaporator, thereby promote backwash liquid rushes at film by fenestra from the per-meate side of inoranic membrane separator inner membrance pipe inboard, thereby the pollutant that will be trapped in the film inboard is washed open, the elimination film pollutes, back flushing device top is provided with a magnetic valve, and control gas enters air bag or barrier film, and the effect of exhaust is arranged.
The force transmission mode that the utility model adopts is gas extruding gasbag or barrier film, air bag or barrier film remake and are used for liquid, it is different from general online backflushing device fully, the granule foreign that can stop fully in the gas enters in the counter-flushing liquid, also can not produce solution gas bubble blockage fenestra and weaken backwash effect.
