Background technology
At present, people generally feel that air quality is optimistic not to the utmost, and air pollution is main cause, and this is also the basic reason causing air quality difference.In the city of 74, China monitoring air quality, there is the air quality in 70 cities not up to standard, time a lot of, even reach severe contamination.The haze event that such as last year, Beijing was seen repeatly, causes the concern of people of the whole China.And the problem of this seriousness of air pollution, within 1 year two years, can eliminate absolutely not, and air purifier good solution route beyond doubt.
The air purifying process of usual employing has: adsorption technology, negative (just) ion technology, catalysis technique, photocatalyst technology, superstructure light mineralising technology, HEPA high efficiency filter technology, electrostatic precipitation technology etc., no matter adopt which kind of technology, it is more complicated all to there is structure in majority, make trouble bothersome, cost is high; Critical piece is short for service life, and often changing parts increases expenses; Some filter screen type dust removals by filtration, superfine little microparticle is likely slipped through the net, and dust removing effects is desirable not to the utmost.
Particularly Cottrell process, utilize high-voltage dc to produce the gas molecule in air is ionized, produce a large amount of electronics and ion, move to the two poles of the earth under the effect of electric field force, the dust granules encountered in moving process in air-flow makes it charged, electrically charged particle moves to pole plate in electric field force effect, realizes being separated of solids or liquid particle and air-flow.Industrial extensive use be tube-type esp and Elex precipitator.Cottrell process and dielectrophoresis technology (Dielectrophoresis, DEP) unlike:
(1) what dielectrophoresis was handled is neutrophil granule, makes the translational motion that it produces due to the effect of dielectric polarization; What electrophoresis was handled is electronics and ion, makes its load produce displacement on dust granules.
(2) in dielectrophoresis, the direction of particle motion and electric field has nothing to do, only relevant with the dielectric constant of itself dielectric constant and medium; In electrophoresis particle motion depend on particle the direction of charged symbol and electric field, direction of an electric field reverses then direction of motion reversion.
(3) dielectrophoresis needs inhomogeneous field; Electrophoresis all can occur in field even or heterogeneous.
(4) size of dielectrophoresis force be proportional to particle diameter cube; It is how much charged that the size of electrophoretic force is proportional to particle institute.
Chinese patent: a kind of dielectrophoresis electrode structure (application number: 201410407467.8, the applying date: 2014.08.19) disclose a kind of electrode with chi structure, known by " a part of wire connecting power positive pole in described first wire group; another part connects power cathode " of claim 1 and description [0005] section, in the application, what pass into is dc source (only having dc source inborn ability both positive and negative polarity) to this electrode.Although applicant sets forth this electrode structure in description [0006] section can produce non-uniform electric field, principle, this non-uniform electric field can not sustainable existence.
After the electrode in medium passes into direct current, because the charged particle that can not offset is due to foregoing electrophoretic effect, converge in opposite polarity electrode surface, produce the effect being similar to electrostatic screen, external electronic field is reduced to 0.Produce the effect of non-uniform electric field between so just not reaching in the electrodes, therefore above-mentioned setting does not reach utility model object.
