[0027] The first support 107 comprises a first support beam and two first side wings arranged on both sides of the first support beam respectively, and the two first side wings are used for supporting two adjacent oil removal water grids 104 respectively. In some examples, the first support 107 is arranged in a reverse T-shaped structure.

[0028] It can be understood that the oil removal water grids 104 are arranged in a spliced broken line distribution in the oil fume hood 101 through the first support 107, so as to expand the area of the lower side of the oil removal water grid 104 contacting the oil fume.

The phase change is generated by using the temperature difference, so that the oil fume particles and aerosol-like oil and water gas condensate gathered into large groups are liquefied on the oil removal water grid 104 under the action of gravity.

[0035] The oil fume enters the processing device from the interception cover net 102, and the jet flow of the composite particle flow generator 103 forms a turbulent flow, so that the oil fume collides with the multiphase composite particle flow, surface adsorption and negative oxygen ion neutralization, thereby gathering into large group particles. At the same time, under the action of wind and negative pressure, the oil removal water grid 104 rapidly loses temperature, and when the oil fume after mixing is generated by the oil removal water grid 104, the radiation fog is generated, and the radiation fog is liquefied and adsorbed on the oil removal water grid 104, and the continuous liquefaction condensation generates a liquid film, liquid drops, and accumulates and flows. The adsorbed oil liquid is liquefied by steam, and the flowing liquid flushes the oil removal water grid 104, so that the oil removal water grid 104 is self-cleaning.
