The working principle is as follows:

before the oil fume removal starts, the stop valves 4 unidirectionally stop the air at the port from entering the common flue 6, and the relative negative pressure state in the common flue 6 is kept.

When removing oil smoke, the third fan on the fume collecting hood 9 works, and the power wind generated by the third fan is sprayed downwards along the annular air outlet 10 of the fume collecting hood 9, so that an air curtain is formed around the cooking bench to collect the oil smoke and steam generated by the cooking bench.

The smoke (oil smoke droplets) primarily condensed by the refrigerant evaporator 18 passes through the filter 17 along the connection pipe 23 and is then ejected, and at the same time, the low-temperature liquid is pumped into the filter cavity 20 through the liquid inlet 25 under the action of the pressure pump, so that the low-temperature liquid is forced to be sprayed out from the water spraying holes 21 of the lower base plate (water columns sprayed out from the water spraying holes 21 can directly impact on fan blades of the fan 22, on one hand, the water columns can be scattered into water mist under the action of impact force, on the other hand, the fan blades can drive the fan to rotate 22 under the action of the impact force to blow the formed water mist out (a power generation device can be additionally arranged on the fan 22 to meet the power requirement of part of equipment operation)), impurities such as oil molecules and the like in the smoke (oil smoke droplets) sprayed by the connecting pipeline 23 are adsorbed on the low-temperature mist and are jointly sprayed into the low-temperature liquid of the liquid collecting tray 12, thereby releasing purified air (containing flavor) from the foam on the cryogenic liquid of the drip pan 12; the air is sucked into the air duct three 1 under the action of the fan four, the water mist is isolated by the demister 26 in turn, and the dry and cold purified air after being thoroughly deodorized by the smell-removing device 27 can be directly discharged into the atmospheric environment.

In addition, when the compressor unit 15 works, the compressor unit, the refrigerant evaporator 18 and the casing heat exchanger 16 are combined into a refrigerant circulating system, impurities and oil-water molecules in the oil smoke in the air duct II 3 are preliminarily adsorbed in a low-temperature condensation mode, meanwhile, heat in the oil smoke is replaced in a heat exchange mode and stored in the roof heat storage water tank 14 in a hot water mode, and the heat storage water tank 14 can provide domestic hot water for floor residents together with the roof solar heat storage water tank.
