Abstract

The present invention relates to a cooking fume purifier using electrostatic field ionization, magnetic field force and gas vortex centrifugal force eccentric rotation action and an oil-repelling technique by using isopotential and identical electric property. Under the action of ionization polarized electrode the fume particles are ionized and charged, and under the action of magnetic field Lorentz force and vortex centrifugal force formed by gas vortex guide plate the charged particles are separated from air channel and under the electric attraction action of adsorption electrode the charge particles are moved toward dirt-collecting tank so as to attain the goal of cleaning fume.

Description

Ionization magnetic deflection composite purifier for cooking fume

One. technical field:

The art of this patent relates to a kind of magnetic field, electric field, gaseous state eddy current guide plate structure, idiostatic with the electrical purifier for cooking fume of aggregate device, especially the electrostatic field ionization and the magnetic field force of sticking oil tech, gaseous state eddy current centrifugal force deflecting action and idiostatic with electrical oily dirt free technology not.

Two. background technology:

As everyone knows, the problem of environmental pollution of China is anxious to be solved, the particularly pollution of atmosphere control.The expert points out: " air pollution of China densely populated areas has 30% kitchen from ' delicious drifting fragrance ', and the pollution level of cooking fume is tens times of outdoor air, and cooking fume contains pollutions such as (smoke exhaust) noise, floating dust, aerosol simultaneously.Contain ' 34 phenylpropyl alcohol pyrroles in the oil smoke ' etc. a large amount of carcinogens, with its be discharged into outdoor can the aggravation atmosphere pollution; Can destroy natural ecological environment ".Therefore cooking fume pollutes and is listed in one of the three big public hazards in city.From July 1 calendar year 2001, China begins the health that compulsory implement " cooking fume discharge standard GWPB5-2000 " is beneficial to the people.The standard code cooking fume must could discharge through processing up to standard.Traditional oil smoke processing method has water film filtering method, media filtration method, Electrostatic Absorption method etc.Because there are secondary pollution in moisture film and media filtration method and are unsuitable for the defective of cold operation, so the application of Electrostatic Absorption method is comparatively extensive.

Traditional high-frequency electric field and electrostatic method mainly are to adopt static that the attraction mechanism (being called for short a step attraction mechanism) of different in nature charged particle is purified, and handle through a large amount of experimental results show that " one-step method ", can not reach discharge standard.This is because the charged attribute of soot particles and inhomogeneous, and some particulate shows electrically hardly, so Electrostatic Absorption or high-frequency electrostatic field do not show electrical particulates to these and can't play catharsis.Through repeated detection, the highest purification efficiency only can reach 60%, also exists simultaneously: cleaning equipment stops up easily, volume big, leak easily, defective such as easy cleaning, outer casing electrification not.At above problem, find through experiment repeatedly: soot particles after culinary art neutralization and wind friction, have 65-60% that ionization takes place approximately and have certain electrically, but and insufficient.Absorption is effective to the charged corpuscle that wherein has a high potential to electric field, and those do not show electrically and the soot particles of electronegative potential continues ionization in high voltage electric field, the electronegative potential particulate is adsorbed on the inwall of the cleaning equipment inwall that is weaker than the charged corpuscle current potential and chimney gradually, do not show electrical particulate and then be not adsorbed, this moment, chimney and cleaning equipment surface had static; And chimney and cleaning equipment inwall block by greasy dirt easily, thereby cause that windage is excessive, chimney and cleaning equipment outer casing electrification and the low phenomenon of purification efficiency.

Three. summary of the invention:

The art of this patent is mainly used in the purified treatment of cooking fume, can solve in " one-step method " static purification because insufficient the causing of the ionization of soot particles can not be with the disadvantage of soot particles absorption, also the problem of stopping up flue and cleaning equipment outer casing electrification owing to the cleaning equipment wall polluting can be solved simultaneously, the purification efficiency of cooking fume can be obviously improved.Four. description of drawings: patent of the present invention is further specified below in conjunction with accompanying drawing.(accompanying drawing is the structural representation of the patented product.)

Purifier is by (1) oil smoke import cover; (2) magnet steel A; (3) magnet steel B; (4) ionization polarization electrode; (5) gaseous state eddy current guide plate; (6) adsorption electrode; (7) dirt collecting tank; (8) insulating flange (9) connecting screw; (10) air-introduced machine; (11) idiostatic electrode A; (12) idiostatic electrode B; (13) preceding air duct; (14) back composition such as air duct.

Oil smoke import cover (1) is made into the bucket type with metallic plate by the required area in kitchen, the upper end of import cover is connected with circular preceding air duct (13), the annular electro of inlaying several belt electrode pins in the front inner wall of preceding air duct on demand is from polarizing electrode (4), the outer wall of the tail end of ionization polarization electrode, air duct up and down parallel correspondence magnet steel A (2) and magnet steel B (3) are set, welding idiostatic electrode A (11) at the outer wall of ionization polarization electrode.Insulating flange (8) is set in the rear end of preceding air duct, the insulating flange that connects the back air duct with connecting screw (9), leading portion below at back air duct (14) is provided with dirt collecting tank (6), inlay some groups of annular adsorption electrodes (7) in the import department of dirt collecting tank, dirt collecting tank communicates with the back air duct, upper inside wall at back air duct leading portion is provided with gaseous state eddy current guide plate (5), gaseous state eddy current guide plate is corresponding up and down with the dirt collecting tank import, stage casing at the back air duct is provided with air-introduced machine (10), the outer wall of back segment at the back air duct welds idiostatic electrode B (12), and ionization magnetic deflection composite purifier for cooking fume has been formed in above structure set.

The specific embodiment:

The particulate of fume pollution material enters oil smoke import cover (1) under the suction of air-introduced machine (10), by ionization polarization electrode (4) its abundant ionization is made it uniform charged; Simultaneously the outer wall at preceding air duct connects and the idiostatic electrical electrode of charged soot particles (11), and the principle of utilizing same sex electric charge to repel each other is no longer polluted the air duct inwall and stopped up air duct by soot particles; Charged soot particles makes charged smokeshade produce deflecting action under the compound action of formed magnetic field Luo Lun taste power and the formed eddy current centrifugal force of gaseous state eddy current guide plate by magnet steel A (2), magnet steel B (3) and breaks away from air duct, charged soot particles is oriented to the dirt collecting tank motion under the electric attraction effect of adsorption electrode (6), thereby reaches the catharsis that separates polluter in the oil smoke.
