Description

A kind of Wetting cooking fume remover and application
Technical field
The invention belongs to environmental technology field, especially a kind of Wetting cooking fume remover and application.
Background technology
Development with national economy and the raising of living standards of the people, catering industry is flourished, diet oil Smoke pollution has become as the third-largest air pollution source being only second to industrial pollution and transportation source in city.Research shows, drink The oil smoke of food industry discharge has become one of important sources of organic matter in the particulate matter of city;Multiple mutagenesis, cause is contained in oil smoke Cancer material is closely related with the generation of the breathing problems such as lung cancer, and therefore fume pollution problem becomes problem demanding prompt solution.
Existing oil smoke treatment technology mostly adopts mechanical, filtering type, electrostatic, or the complex between them Formula, mechanical cooking fume remover is only effective to oarse-grained oil droplet, because little particle can not be entered air by detention with flue gas, Fume purifying efficiency is low, and after being used alone purification, oil smoke can hardly qualified discharge.When filtering cooking fume purifier is with running Between prolongation, exist filtrate hold susceptible to plugging problem lead to pressure drop increase, need periodically changed or cleaned filtrate, troublesome maintenance, Operating cost is high, and power of fan is big, is also easy to produce noise pollution.Electrostatic have viscosity oil droplet and be liable to stick to discharge electrode and dust The drawbacks of extremely go up, leads to electrostatic oil fume cleaning equipment to decline running a period of time after-purification efficiency, especially for being received The situation of the mist of oil poor fluidity of collection, adhesion problem is more prominent.Therefore need a kind of new cooking fume control equipment badly to solve State problem.
By retrieval, find following two patent publication us related to present patent application:
Smoke purifier (CN102814082A), including smoke purifier housing, described smoke purifier housing surrounds It is provided with least 2 deflectors, described deflector is curved around any one straight line of cavity vertical direction by cavity bottom in cavity Song sets up, and there is gap between adjacent two deflectors, and be located at the deflector on upper strata the inward flange of overlook direction or and Outward flange projection falls in the deflector positioned at lower floor in the projection of overlook direction, and described inward flange is that deflector is net away from oil smoke Change one side of casing body, outward flange is deflector near smoke purifier housing.Beneficial effect:To be taken out using broken blower fan The ball-type oil smoke wheal that blower fan is brought fully is smashed, and forms soft wind, then row spray, the spraying effect greatly improving.Spiral Climb, increase the time of staying in machine for the soot gas, strengthen spraying effect, and can be formed between the layers one week The moisture film of annular, also can be clashed into moisture film in soot gas uphill process.
A kind of fume purifier of fume (CN101601954A), including the case with cooking fume intake and flue gas outlet Body, the spraying mechanism being located in casing and the water circulation mechanism being configured at lower box, are provided with a dividing plate in described casing, every The bottom of plate is formed with separator channels, and described spraying mechanism is located in described cooking fume spray chamber, and with described water Cycling mechanism is connected;It is provided with flue gas water removal body, described flue gas is drawn and described smoke extraction chamber phase in described smoke extraction chamber With.The power power consumption of water circulation mechanism can be reduced, and good to the spray deoiling effect of cooking fume;Overall structure is terse, can embody The convenience using and economy.
