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 fluid connection remittance liquid runner that sees through chamber, this converges liquid runner by main liquid mouth discharge.

And the electrode pair that is packed in the infiltration deckle board portals and is communicated with by electric wire via hole and electric wire made on right casing, this electric wire portals and draws the extraneous power supply of rear connection.

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 the dielectrophoresis technology, reduce and even eliminate the film pollution occurred and block up the film phenomenon in osmosis process with physics mode, make membrane component self form fluid passage and liquid cavity, improve the film transit dose, perfection has overcome existing flat membrane component and can not break away from pond, can not add the easily stifled problem by dirt of malleation infiltration and face, has high novelty.

2, this assembly is membrane component upper set supporting construction, container cavity, the fluid passage function at overcurrent mainboard and the overcurrent flat board of monolithic, then along the straight line repeated arrangement, form, himself forms container cavity, can make this flat membrane component break away from the pond restriction, can lay and turn to three-dimensional the laying by plane, save space.

3, this component design the self supporting structure of overcurrent mainboard and overcurrent flat board, can under larger normal pressure, use thus, enlarged the kind that can apply film, electrode has wherein strengthened the filter capacity of film by the dielectrophoresis technology.

The specific embodiment

Below by the drawings and specific embodiments, the invention will be further described, but the present invention is not limited to following embodiment, and any change of making on the present embodiment principle or replacement scheme, all fall among the scope of protection of present invention.

The dull and stereotyped permeable membrane element of a kind of dielectrophoresis, it is the film stacking structure formed by left outside shell 2, right casing 7, infiltration mainboard 4, infiltration deckle board 3, infiltration lamina membranacea 5, electrode 6, left outside shell and right casing are for being symmetrical arranged, be spaced between left outside shell, right casing and be fixed with infiltration mainboard and infiltration deckle board, all be sealed and installed with the infiltration lamina membranacea between adjacent infiltration mainboard and infiltration deckle board, on the infiltration deckle board, horizontal uniform interval is equipped with electrode pair.

Be shaped with liquid inlet 9 at the right casing upside, this liquid inlet is communicated with multiple tracks (the present embodiment accompanying drawing the is three roads) flow channel for liquids 8 of the common formation of infiltration mainboard and infiltration deckle board institute, this flow channel for liquids secondary channels 10 radially made by the infiltration mainboard is communicated with the permeate chamber 21 between infiltration mainboard and infiltration lamina membranacea, the lower end of this permeate chamber is shaped with secondary channels 15, and this secondary channels is communicated with and passes through dope outlet 17 discharges of left outside shell with dope runner 16; Liquid between infiltration mainboard and permeable membrane sees through that the infiltration lamina membranacea is laggard enters to permeate deckle board, form and see through chamber 20 between infiltration lamina membranacea and infiltration deckle board, should see through indoor liquid and enter main fluid runner 13 by the made secondary channels 14 in infiltration deckle board both sides, this main fluid runner is discharged by the liquid outlet 12 of right casing; In addition, the liquid that sees through chamber also can be communicated with remittance liquid runner 18 by secondary channels 19, and this remittance liquid runner is discharged by main liquid mouth 1.
