Description
Technical field
The present invention relates to membrane filtration device, more particularly to a kind of immersion filter.
Background technology
During separation of solid and liquid, membrane filtration technique is one of the most frequently used technology.The principle of membrane filtration is exactly in mistake
The both sides of filter medium form certain pressure differential, and insoluble suspended material is retained by filter medium, formed filter cake, and solvent, can
The particulate that soluble substance and part are less than filter medium space can form clear filtrate by filter cake and filter medium, and then solid
The effect of liquid separation.
Submerged membrane element is directly immersed in non-filtrate, it is not necessary to pressure vessel, so cost is lower.Immersion membrane element
Part uses dead-end filtration mode.The general principle of dead-end filtration is that under the pressure differential effect of pump, the liquid in non-filtrate passes through
Film surface micropore is discharged as clear filtrate, and the suspension more than film surface micropore is then trapped within film surface formation cake layer.Cake layer
Thickness can constantly increase, so as to increase filtration resistance, in order to ensure filtering is normally carried out, it is necessary to periodically remove the filter on film surface
Cake layer.
In known scrub membranes method, most of mixture using gas and liquid washes away the film.And liquid
Partially liq and energy consumption can inevitably be wasted using the liquid after purification, such a operation mostly.
The content of the invention
It is an object of the present invention to solve above-mentioned waste partially liq and energy consumption problem during scrub membranes, carry
