Description
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：
