Description
Technical field
This utility model belongs to air filtration technical field, particularly to a kind of domestic using column dielectrophoresis electrode
Air purifier.
Background technology
At present, people generally feel that air quality is the most optimistic, and air pollution is main cause, and this is also to cause air quality poor
Basic reason.In the city of 74, China monitoring air quality, the air quality having 70 cities is the most up to standard, the when of a lot
Even up to severe contamination.The haze event that such as last year, Beijing was seen repeatly, causes the concern of people of the whole China.And air pollution this
The problem of one seriousness, within 1 year two absolutely not, load can eliminate, and air purifier is undoubtedly good solution route.
Conventional Household Air Purifier, the air purifying process generally used has: adsorption technology, negative (just) ion skill
Art, catalysis technique, photocatalyst technology, superstructure light mineralising technology, HEPA high efficiency filter technology, electrostatic precipitation technology etc., no matter
Using which kind of technology, it is more complicated all to there is structure in majority, makes trouble bothersome, and cost is high；Critical piece is short for service life, often
Change parts and increase expenses；Some filter screen type dust removals by filtration, superfine little microparticle likely slips through the net, and dust removing effects is managed not to the utmost
Think.
Particularly Cottrell process, is to utilize high-voltage dc to produce to make the gas molecule in air ionize, produces big
Amount electronics and ion, move to the two poles of the earth under the effect of electric field force, and 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, it is achieved solids or liquid particle separate with air-flow.Industrial
Wide variety of is tube-type esp and Elex precipitator.Cottrell process and dielectrophoresis technology
Unlike (Dielectrophoresis, DEP):
(1) what dielectrophoresis was handled is neutrophil granule so that it is the translational motion produced due to the effect of dielectric polarization；Electricity
What swimming was handled is electronics and ion so that it is load produces displacement on dust granules.
(2) in dielectrophoresis, particle motion is unrelated with the direction of electric field, dielectric constant the most with itself and medium
Dielectric constant relevant；In electrophoresis particle motion depend on granule charged symbol and the direction of electric field, electric field side
To inverting then direction of motion reversion.
(3) dielectrophoresis needs inhomogeneous field；Electrophoresis all can occur in field uniform or heterogeneous.
(4) size of dielectrophoresis force be proportional to particle diameter cube；It is charged that the size of electrophoretic force is proportional to granule institute
The number of lotus.
Chinese patent: a kind of dielectrophoresis electrode structure (application number: 201410407467.8, the applying date:
2014.08.19) a kind of electrode with chi structure is disclosed, " described by claim 1 and description [0005th] section
A part of wire connecting power positive pole in first wire group, another part connects power cathode " understand, this electrode is in application
In, be passed through is DC source (only DC source inborn ability both positive and negative polarity).Although applicant explains in description [0006th] section
State this electrode structure and can produce non-uniform electric field, but this non-uniform electric field can not sustainable existence from principle.
After the electrode in medium is passed through unidirectional current, imitate due to foregoing electrophoresis because of the charged particle that can not offset
Should, converging in opposite polarity electrode surface, produce the effect being similar to electrostatic screen, external electronic field is reduced to 0.So
Producing the effect of non-uniform electric field between just not reaching in the electrodes, the most above-mentioned setting does not reaches utility model purpose.
