Background technique

The catering industry is an indispensable and important part of modern people's life, and the oil fume pollution produced in the kitchen has caused great harm to the environment and human body. At present, the high-voltage electrostatic precipitator method is generally used for oil fume filtration. Under the action of Coulomb force in the electric field, the charged dust particles (oil fume) move towards the dust collecting pole and are adsorbed on the dust collecting pole. After a period of use, it needs to be cleaned It is very difficult to clean the dust collector and the operating cost is high. A large amount of sewage is generated during the cleaning process, causing secondary and greater pollution. There are also equipment and methods for absorbing oil fume by mist or active adsorption, but there is also the problem of generating a large amount of sewage and causing secondary pollution.
