Description
Technical field
The present invention relates to technology for cooking fume control field, be specifically related to a kind of magnetic field auxiliary electrostatic formula cooking fume remover.
Background technology
Famous medical journal " lancet breathing medical science " research report shows, the whole world population of about four one-tenths, because of culinary art and the oil smoke of heating generation, smog and by health threat.During fried, cooking, PM2.5 rises violently the most rapidly 8 times to nearly 20 times, reaches severe contamination rank, and wherein in cooking 5 minutes, PM2.5 numerical value 38 micrograms/cubic meter the most from the outset increases to 787 micrograms/cubic meter.The harm that the indoor environmental pollutions such as kitchen fume are brought can not be ignored, even can be lung cancer caused etc. disease.But the most effectively solve kitchen fume, be a professional difficult problem.
Existing most of kitchen hood, simply enters oil smoke air from kitchen, although so kitchen obtains a certain degree of purification, but makes environment be destroyed simultaneously.The research data of Chinese Academy of Sciences's atmospheric physics institute shows, in Pekinese PM2.5 source, motor vehicles, fire coal and the construction fugitive dust proportion received much concern is about 50%, and be not held in esteem depending on kitchen fumes ratio unexpectedly accounted for 13%, even above the 8% of industrial discharge.Even if the most more advanced high-voltage electrostatic fume eliminating technology, owing to there is the non-rational Design on Plane of part-structure division at high-pressure electrostatic, it is clean that it still cannot really make oil smoke process.
The Chinese invention patent " high-voltage static fume treating equipment " having an Application No. 01110705.7 (Publication No. CN1380143A) discloses a kind of high-voltage static electricity fume processor, and its principle is to adsorb soot particles by electrostatic field.This fume treatment device oil smoke processing unit is divided into three grades, and the first order is water conservancy diversion oil-collecting ball oil smoke processing unit, and second and third level is spiral stream guidance oil-collecting slot type oil smoke processing unit, and also is provided with multiple oil collection plate to adsorb oil smoke.Or, the Chinese utility model patent " composite type electrostatic oil-fume purifying " of Patent No. 200620014431.4 (Publication No. CN201002053Y) discloses a kind of composite type electrostatic oil-fume purifying, and its key component has mechanical separation bubble homogenizer, static electric field dust removing units and odor filtration device.Wherein, mechanical separation gas flow homogenization device is to slow down oil smoke flow velocity by S type baffle plate, removes thick smoke particle.The absorption of slowing down of elaioleucite flow velocity, beneficially oil sump tank.Corona electrode in static electric field uses double zigzag, controls the distance ratio of corona electrode and corona electrode and corona electrode and dust collection plate, can overcome the phenomenons such as inverse ionization, corona hypertrophy, arcing.Or, the Chinese invention patent " high-frequency electrostatic electricity air-curtain type fume exhauster " of Application No. 02135249.6 (Publication No. CN1465918A) discloses a kind of high-frequency electrostatic air-curtain type fume exhauster, and this invention have employed the mode purifying oil fume that air curtain device combines with electrostatic degreasing unit.The employing of air curtain device effectively limits the diffusion of oil smoke, and the combination with electrostatic field is more beneficial for the purification of oil smoke.Or, the Chinese invention patent " near-suction electrostatic smoke purifier " of Application No. 200910137136.6 (Publication No. CN101566363A) discloses a kind of near-suction electrostatic smoke purifier, it has in anion gas can be passed to casing by anion generator and in air in kitchen unlike common electrostatic smoke purifier, and this device does not contacts with oil smoke.In the design of structure, effectively exhaust zone is isolated with respiratory region.Or; the Chinese utility model patent " a kind of electric field structure purified for electrostatic oil fume " of Application No. 201220387883.2 (Publication No. CN202778715U) discloses a kind of electric field structure purified for electrostatic oil fume; this electric field structure is constituted by organizing cylindrical shape honeycomb electric field more; many group electric fields distribution in a casing simultaneously; decrease distribution line; alleviate the distribution complexity of whole cooking fume remover, decrease the fault in productions such as the shutdown owing to line fault causes, stopping production.And, the Chinese invention patent " ionization magnetic deflection composite purifier for cooking fume " of Patent No. 02124982.2 (Publication No. CN1465445A) discloses a kind of ionization magnetic deflection composite purifier for cooking fume, the operation principle of this device is to utilize magnetic field and gaseous state eddy current baffle plate to make polarized elaioleucite direction of motion deflection dirt collecting tank, again by the adsorption electrode on accumulator tank, soot particles is adsorbed onto in accumulator tank.In order to no longer be blocked by greasy dirt in air duct during purifying oil fume, the air duct of this device is charged (contrary with charged elaioleucite), it is possible to use the principle that the same sex is repelled each other stops greasy dirt to adsorb in air duct.
Knowable to above-mentioned electrostatic oil fume deaner, the operation principle great majority of existing various electrostatic oil fume deaner are all to be made elaioleucite polarize by polarization device, again by the electric field of oil sump tank, make charged elaioleucite change movement locus under the effect of electric field force, be finally adsorbed on the positive plate of oil sump tank.Although collecting the most of oil particle in oil smoke by electrostatic field, but still the effect of thorough purifying oil fume can not be reached.The improved method of most of cooking fume removers, is all the detergent power optimizing purification range hood by changing device profile.But also there is being realized by interpolation magnetic field of minority, such as Chinese invention patent " ionization magnetic deflection composite purifier for cooking fume " although have employed power that magnetic field deflects as elaioleucite but owing to the carried charge of different elaioleucites differs, and the T-type structure of this device, elaioleucite is difficult to all deflection and is adsorbed by electrostatic field to accumulator tank.It addition, this to be designed with air duct charged to prevent greasy dirt from adsorbing, be a great potential safety hazard to user.
