In this way, when the oil with light specific gravity accumulates in the height direction Z to a height greater than the oil discharge port 231 , the oil will be discharged from the oil discharge port 231 to achieve the effect of oil-water separation and purification. At the same time, the water flow remaining in the water collecting tank 230 and separated from the grease will be extracted by the water suction port 233, and the dust deposited on the bottom of the water collecting tank 230 can be discharged from the sewage outlet 232 after the sewage outlet 232 is opened. discharge.

Referring to FIGS. 2 , 6 and 9 , it is worth noting that the present invention can extract the water flow separated from the grease in the water outlet space 230 b through the pump 44 , so that the water flow passes through the water pipe group 43 and then returns to the water curtain pipe 42 , and the water wall pipe 41 , thereby forming a circulating circuit of water supply flow between the water collecting tank 230 , the water wall pipe 41 , the water curtain pipe 42 , and the S-shaped channel 25 .

Through the above description, the advantages of the foregoing embodiments can be summarized as follows:

1. The new model can generate vortex by the cyclone dust collecting unit 3, and separate oil mist, dust and air by centrifugal force, and at the same time, it can also combine the oil mist and air separated by the water flow discharged from the water wall pipe 41. Dust, so that the water flow drives the oil mist and dust to flow, and is smoothly discharged from the sewage collection port 311 to achieve the effect of the first filtration.

2. What is important is that when the air enters the bellows 21 and rises along the S-shaped channel 26, it can again impact the S-shaped water curtain leaking down from the water curtain pipe 42, so that the air is trapped in the air. The residual oil mist and dust can be fully mixed in the water flow to achieve the effect of secondary filtration and enhanced air purification.
