Abstract
The invention relates to a dielectrophoresis flat permeable membrane component, which is a membrane stack structure composed of a left shell, a right shell, permeation mainboards, permeation frame boards, permeation membrane boards, and electrodes. The permeation mainboards and the permeation frame boards are fixedly arranged between the left shell and the right shell at intervals. The permeation membrane boards are hermetically installed between adjacent permeation mainboards and permeation frame boards, and electrode pairs are transversely and uniformly distributed and mounted on the permeation frame boards at intervals. The component employs a dielectrophoresis technology to reduce or even eliminate membrane fouling and membrane blocking phenomena in a permeation process by a physical way, so that a membrane element itself can form a fluid passage and a liquid cavity, the membrane permeation amount can be enhanced, and the problems that existing flat membrane elements cannot break away from a pool, a positive pressure cannot be added for permeation and the membrane surfaces are likely to be polluted and blocked can be overcome perfectly. Thus, the dielectrophoresis flat permeable membrane component has very high innovativeness.

And the described remittance of the fluid connection through room liquid runner, this remittance liquid runner is discharged by main liquid mouth.
And the electrode pair being packed in infiltration deckle board to be portalled with electric wire made on right casing by electric wire via hole and is communicated with, this electric wire portals and draws the extraneous power supply of connection afterwards.
And described infiltration lamina membranacea is reverse osmosis membrane, or it is forward osmosis membrane.
Advantage of the present invention and good effect are:
1, this assembly adopts dielectrophoresis technology, reduce the fouling membrane and stifled film phenomenon even eliminating and occur in osmosis process for physically, membrane component self is made to form fluid passage and liquid chamber, improve film transit dose, perfection overcome existing flat membrane component can not depart from pond, can not add malleation infiltration and face easily by the problem that dirt is blocked up, there is high novelty.
2, this assembly is membrane component upper set supporting construction, container cavity, the fluid passage function of overcurrent mainboard at monolithic and overcurrent flat board, then linearly repeated arrangement, himself forms container cavity, this flat membrane component can be made to depart from pond restriction, can be laid by plane and turn to three-dimensional laying, save space.
3, this component design self supporting structure of overcurrent mainboard and overcurrent flat board, can use under larger normal pressure thus, expand the kind can applying film, electrode wherein enhances the filter capacity of film by dielectrophoresis technology.
