Description

Magnetic field auxiliary electrostatic formula oil fume purifier
Technical field
The present invention relates to technology for cooking fume control field, and in particular to a kind of magnetic field auxiliary electrostatic formula oil fume purifier.
Background technology
Famous medical journal《Lancet breathes medical science》Research report shows, the population in about four one-tenth of the whole world, because cooking and taking Oil smoke caused by warm, smog and by health threat.When frying, cooking, PM2.5 then rises violently rapidly 8 times to nearly 20 times, reaches tight 38 micrograms/the cubic meter of PM2.5 numerical value just from the outset increases to 787 micrograms/vertical in heavily contaminated rank, wherein cooking 5 minutes Square rice.Harm can not be ignored caused by the indoor environmental pollutions such as kitchen fume, or even can trigger the diseases such as lung cancer.But how to have Effect solves kitchen fume, is a professional problem.
Oil smoke, is simply discharged into air by existing most of kitchen hoods from kitchen, although so kitchen obtains one Determine the purification of degree, but destroyed environment simultaneously.The research data of Chinese Academy of Sciences's atmospheric physics institute shows, Pekinese In PM2.5 sources, the motor vehicle, fire coal and the construction fugitive dust proportion that receive much concern are about 50%, without being held in esteem what is regarded Kitchen fumes ratio has accounted for 13%, even above the 8% of industrial discharge unexpectedly.Even if high-voltage electrostatic more advanced at present removes Oil smoke technology, due to part occurs in high-pressure electrostatic) the non-rational Design on Plane of structure division, it still really can not cause at oil smoke Reason is clean.
There is the Chinese invention patent of an Application No. 01110705.7 (Publication No. CN 1380143A)《High-pressure electrostatic oil Fume treating device》A kind of high-voltage static electricity fume processor is disclosed, its principle is to adsorb soot particles by electrostatic field.The oil Cigarette processor oil smoke processing unit is divided into three-level, and the first order is water conservancy diversion oil-collecting ball oil smoke processing unit, and second and third level is spiral Water conservancy diversion oil-collecting slot type oil smoke processing unit, and multiple oil collection plates are also provided with to adsorb oil smoke.Or Patent No. The Chinese utility model patent of (200620014431.4 Publication No. CN 201002053Y)《Composite type electrostatic oil-fume purifying》 A kind of composite type electrostatic oil-fume purifying is disclosed, its chief component has mechanical separation bubble homogenizer, static electric field Dust removing units and odor filtration device.Wherein, mechanically decoupled gas flow homogenization device is to slow down oil smoke flow velocity by S type baffle plates, is removed Remove thick smoke particle.Elaioleucite flow velocity slows down, and is advantageous to the absorption of oil sump tank.Corona electrode in static electric field is using double Zigzag, corona electrode and corona electrode and the distance of corona electrode and dust collection plate ratio are controlled, inverse ionization, corona can be overcome Phenomena such as hypertrophy, arcing.Or (the Publication No. CN 1465918A of Application No. 02135249.6)Chinese invention patent《It is high Frequency electrostatic electricity air-curtain type fume exhauster》A kind of high-frequency electrostatic air-curtain type fume exhauster is disclosed, the invention employs air curtain device With the mode purifying oil fume that electrostatic degreasing unit is combined.The use of air curtain device effectively limits the diffusion of oil smoke, and quiet The combination of electric field is more beneficial for the purification of oil smoke.Or (the Publication No. CN of Application No. 200910137136.6 101566363A)Chinese invention patent《Near-suction electrostatic smoke purifier》A kind of near-suction electrostatic smoke purifier is disclosed, with It has anion generator that anion gas are defeated to empty with kitchen in casing unlike common electrostatic smoke purifier In gas, the device does not contact with oil smoke.In the design of structure, effectively exhaust zone is isolated with respiratory region.Or application number For 201220387883.2 (Publication No. CN202778715U)Chinese utility model patent《It is net that one kind is used for electrostatic oil fume The electric field structure of change》A kind of electric field structure for electrostatic oil fume purification is disclosed, the electric field structure is by multigroup cylindrical shape honeybee Nest electric field is formed, and multigroup electric field while the distribution in a casing, is reduced distribution line, is alleviated whole oil fume purifier Distribution complexity, reduce the fault in production such as the shutdown caused by line fault, stopping production.And Patent No. 02124982.2 (Publication No. CN1465445A) Chinese invention patent《Ionization magnetic deflection composite cooking fume purification dress Put》Disclosing a kind of ionization magnetic deflection composite purifier for cooking fume, (operation principle of the device is gentle using magnetic field The elaioleucite direction of motion that state vortex baffle plate makes to be polarized is inclined to dirt collecting tank, then by the adsorption electrode on accumulator tank, by oil smoke Particle absorption is into accumulator tank.In order to no longer be blocked during purifying oil fume in air duct by greasy dirt, the air duct of the device is Powered (opposite with powered elaioleucite), the principle that identical charges repel each other can be utilized to prevent greasy dirt from adsorbing in air duct.
It was found from above-mentioned electrostatic oil fume deaner, most of operation principle of existing various electrostatic oil fume deaners is all It is that elaioleucite muon polarization, then the electric field by oil sump tank are made by polarization device, powered elaioleucite is changed fortune in the presence of electric field force Dynamic rail mark, is finally adsorbed on the positive plate of oil sump tank.Although collecting most of elaioleucite in oil smoke by electrostatic field, The effect of thorough purifying oil fume can not still be reached.The improved method of most of oil fume purifiers, it is by changing device profile To optimize the detergent power of purification range hood.But also there is being realized by adding magnetic field for minority, such as Chinese invention patent 《Ionization magnetic deflection composite purifier for cooking fume》Although employing the power that magnetic field deflects as elaioleucite but due to not Carried charge with elaioleucite differs, and the T-type structure of the device, and elaioleucite is difficult all to deflect to accumulator tank to be inhaled by electrostatic field It is attached.In addition, the design uses air duct powered to prevent greasy dirt from adsorbing, it is a great potential safety hazard to user.
