Due to the double purification functions of water mist capture and inertia separation, the oil fume purification rate is greatly improved, and the water loss consumption is reduced. The total mesh area of the fish scale mesh baffle 7 ensures the air flow circulation, reduces the wind resistance and reduces the energy consumption.
The circulating water pump 28 continuously sucks circulating water from the water outlet box body 32 of the purifying intelligent control box 200, the circulating water is pressurized to the spray head of the spraying and purifying device 5 through the circulating water pipe 9, and water mist is sprayed to the air inlet oil smoke flow and air speed adjusting plate 12.
