The utility model is characterized in that the clapboards (7) and (9) and the millipore ceramic membrane pipe (12) are welded and stuck into a sealed frame in the container (1), the container (1) is divided into the filtering medium zone (2) and the clear solution zone (3). The utility model has the advantages of high efficiency of operating, wide range of application, good effects of separating and purifying, double advantages of filtering and air bearing, long circle and excellent efficiency of bounce-back and regeneration. The utility model is widely applied in the filtering of waste water and waste gas.

Description

The high-performance ultrafiltration device

The utility model relates to a kind of filter:

Before the utility model, there is filter in the system of decontaminating liquid, device such as filter, air supporting, though their suspensions in can filter liquide with separate greasy dirt, but all existing many deficiencies and worn-out sick, mainly is that operational efficiency is low, inferior separating effect, can oil removing and can not remove suspension, it is frequent etc. that frequent complicated, the filtrate of short, maintenance filter cycle can not regenerate and change.

The purpose of this utility model is exactly to overcome above deficiency and a kind of micropore ceramics film pipe ultrafiltration apparatus of proposing.

Advantage of the present utility model is: the operational efficiency height, and wide accommodation, the isolation of purified effect is superior, has to filter and pneumatically supported two-fold advantage, and recoil long-acting rate of regeneration period is splendid.

Invention main points of the present utility model are in the tank body (1), through welding, stick into the sealing frame, tank body (1) are divided into filtration liquid zone (2) and clear liquid area (3) with dividing plate (7), (9) and micropore ceramics film pipe (12).Make most of liquid adsorb its suspension, oils and colloid shape material in through the surface of micropore ceramics film pipe (12) and micropore through pressurization; Under the oxidation of the oxygen that liquid flow and liquid discharge, thereby take away and its harmful substance of oxidation, suspension, oils and colloid shape material obtain better clean-up effect.

Operation principle of the present utility model is:

One, technological process principle is the alternate cycles of two processes of ultrafiltration and flushing

Feed liquor to be filtered enters into waste liquid district (2) through inlet (4) and passes through suspension and oils and the colloid substance that liquid is held back in micropore ceramics film pipe (12) ultrafiltration absorption again; Most of scavenging solution enters into clear liquid area (3) through liquid outlet (5) bleeder.Then fraction concentrated liquid band the suspension that is retained down, and oils and colloid substance are through concentrated solution outlet (6) bleeder.In filtration,, when resistance (pressure reduction) reaches maximum the permission, should carry out backwash because tube-surface film and micro-porous adsorption are constantly cut out and stayed, and membrane pores reduces gradually, and liquid flowing resistance constantly increases.When carrying out backwash, carbonated drink (compressed air) is by the ceramic membrane tube wall, by means of its shearing force, impulse force and particle collision friction cleaning ceramic film pipe, and dirt is discharged in will installing.

Two, oil, outstanding clean thing are removed mechanism

Mechanism	General introduction
Mechanism	General introduction	1, every the filter tool every the filter accidental contact filtration	Particle diameter is intercepted and captured owing to contact accidentally less than the particle in pore crack greater than the particle tunicle pipe elimination particle diameter of ceramic-film tube hole
2, precipitation, collision	The particle heavier in film device waste liquid district do not precipitate with the streamline motion
2, precipitation, collision		3, intercept and capture	The particle of many streamline motions contacts and is removed with the film tube-surface
4, adhere to	When the flocculation particle passes through ceramic-film tube with oil, they will be attached to the film tube-surface, because some particle of impulsive force of liquid stream and air-flow as yet firm attachment when ceramic-film tube is surperficial, will be punched into ceramic membrane tube wall deep layer by liquid or gas, after ceramic-film tube stops up gradually, surface shear power, resistance just begins to increase, so that make ceramic-film tube can not remove any suspension and oil, some suspensions may penetrate, fluid is exceeded standard, thereby just should begin backwash.	3, intercept and capture
4, adhere to		5, the interaction of chemisorptive bond absorption chemistry	Oil and particle are in case contact this particle and oil and can work and quilt floats and obtains owing to one or both mechanism wherein with ceramic-film tube surface or with other particle surface
6, the absorption of the moving electricity absorption of physical absorption Electrostatic Absorption Van der Waals force
	7, flocculation	When contacting with less threshing, bulky grain it can be caught, and forming bigger particle, these bigger particles will be removed owing to above-mentioned one or more mechanism work
8, physics screening	7, flocculation		The particle that particle that particle diameter is big and particle diameter are little is held back by the ceramic-film tube skin covering of the surface, oxidation under liquid flow and buoyancy and taking out of

Concrete structure of the present utility model and purpose are born by following enforcement and accompanying drawing thereof:
