The work process of the present invention is:
Feed liquid enters in pressure casing by the former water inlet of intake end cover, from flow guiding disc with pressure
Former aquaporin between shell flows to the other end of assembly, enters flow guiding disc at the other end by passage
In filtration channel, processed liquid flows fast through a side form of disc-type film bag with the shortest distance
Face, then 180 ° of another faces reversing disc-type film bag, then from the notch stream at flow guiding disc center
Enter to next flow guiding disc, thus formed by the flow guiding disc circumference-center of circle-circumference-circle on film surface
Double serpentine routes of the heart, concentrated solution finally from dense water out flow out.Produce water edge in the middle of diaphragm
Latticed flow-guiding cloth flows to the product aquaporin that center pull rod is peripheral, by the product water out row of charging end cap
Go out.Due to the dielectric polarization ability lower relative to water, solid particle is at Yuan Shui (material liquid)
In be usually expressed as negative dielectrophoresis character；I.e. in unshapeliness electric field, solid particle is by weak
Direction of an electric field moves.Former water (material liquid) is through the surface of film, and the electrode installed under film provides
Unshapeliness electric field needed for dielectrophoresis force.When in former water (material liquid), solid particle is near film,
I.e. when electrode, will be displaced from and fouling membrane and knot cannot be so decreased or even eliminated near film
The generation of structure, slows down the concentration polarization phenomenon even avoided in membrane separation process.Due to pressure effect
With formation electric double layer, hydrone laterally produces water liquid side and migrates, improves film saturating from waste water (material liquid)
Excess.
Dielectrophoresis concept involved in the present invention and operation principle be:
Dielectrophoresis (Dielectrophoresis) technology has been successfully applied to biomedical work
Industry separates, richness is amassed, capture microgranule and cell.What this technology described is in non-well-balanced electric field
The translational motion that neutral corpuscle produces due to the effect of dielectric polarization, produces the dipole on microgranule
Square can be represented by two identical carried charges but opposite polarity electric charge.When they are at particle interface
During upper mal-distribution, produce a macroscopical dipole moment.When this dipole moment is positioned at unshapeliness electricity
In Chang, the different of the local electric field strength on microgranule both sides produce resulting net force, referred to as a dielectrophoresis
Power.Owing to the microgranule that is suspended in medium has different dielectric properties (dielectric constant) from medium,
Microgranule can by or the direction of higher electric field intensity move, be referred to as positive dielectrophoresis, or
The direction of more weak electric field intensity is moved, the most negative dielectrophoresis.
In membrane filtration separation liquid liquid occur separation permeable membrane pollute, be all solid particle (microgranule,
Colloidal particles, solute crystalline solid, antibacterial is relative with insoluble Organic substance drop and larger molecular organics
Exist in liquid.In such a system, due to solid particle and its liquid suspended
The difference of dielectric polarization ability, solid particle is pushed away electrode or by solid particle by dielectrophoresis force
Absorption, on electrode, shows or negative dielectrophoresis character or positive dielectrophoresis character.
Due to the dielectric polarization ability lower relative to water, solid particle generally shows in waste water
For negative dielectrophoresis character；I.e. in unshapeliness electric field, solid particle is moved to weak electric field direction
Dynamic.As it is shown in fig. 7, waste water (material liquid) is through the surface of film, the electrode installed under film carries
For the unshapeliness electric field needed for dielectrophoresis force.When solid particle is near film, i.e. near interdigital electricity
During pole, will be displaced from and cannot be near film.Fouling membrane and the generation of stifled film are so decreased or even eliminated.
As above, due to the dielectric polarization ability lower relative to water, solid particle is at waste water for principle
(material liquid) is usually expressed as negative dielectrophoresis character；I.e. in unshapeliness electric field, solid
Granule is moved to weak electric field direction.While water passes through film flow direction driving liquid side from material liquid side,
Dielectrophoretic force solute in material liquid is moved apart and cannot near film, solute can not at film surface enrichment,
So slow down and even avoid in Flat Membrane separating technology because water causes to driving liquid side from material liquid effluent
Concentration polarization phenomenon, improve water transit dose.
Although disclose embodiments of the invention and accompanying drawing for the purpose of illustration, but the technology of this area
Personnel are understood that without departing from the present invention and spirit and scope of the appended claims, various
Replace, to change and modifications be all possible, therefore, the scope of the present invention be not limited to embodiment and
Accompanying drawing disclosure of that.
