The plurality of spray heads 502 are evenly arranged below the annular pipe 501, so that the spraying of the treatment liquid is more uniform, which is conducive to the full contact between the treatment liquid and the exhaust gas.

[0030] Reference Figure 3 In order to achieve the purpose of introducing the treatment liquid, a liquid guiding component is connected between the annular spray pipe 5 and the treatment liquid tank 4, and the liquid guiding component includes a first liquid pump 9.

[0032] Reference Figure 1 In order to achieve the purpose of allowing the waste gas in the treatment tank 1 to move upward and come into more complete contact with the treatment liquid, a drain pipe 6 is installed at the bottom of the treatment tank 1, and a liquid infusion hose 7 is fixedly connected to the bottom of the drain pipe 6.

[0034] The functional principle of the utility model can be explained through the following operation modes:

[0035] The waste gas generated during the food production process enters the spiral processing tube 3 through the waste gas inlet pipe 2 and flows downstream along the spiral processing tube 3. At the same time, the control valve 22 is closed, the control valve 15 is opened, the second liquid pump 12 works, and the treatment liquid in the treatment liquid tank 4 enters the spiral processing tube 3 through the liquid guide tube 3 13 and the liquid guide tube 4 14, and contacts with the waste gas in the spiral processing tube 3 to pre-treat the waste gas.

[0036] The pre-treated waste gas is discharged from the bottom of the spiral treatment tube 3 into the treatment tank 1. The vacuum pump 17 works to pump the gas in the treatment tank 1 so that the waste gas flows upward. At the same time, the first liquid pump 9 works to allow the treatment liquid to enter the annular tube 501 through the liquid guide tube 1 10 and the liquid guide tube 2 11 and then be sprayed to the waste gas moving upstream through the spray head 502. The waste gas further contacts with the treatment liquid, and the waste gas treated by the treatment liquid is discharged through the air guide pipe 18 and the air outlet pipe.

[0037] The treated liquid in the treatment tank 1 flows into the filter box 19 through the drain pipe 6 and the infusion hose 7. The control valve 15 can be closed and the control valve 2 22 can be opened. At this time, the second liquid pump 12 can pump the treated liquid in the filter box 19 into the spiral treatment pipe 3 to pre-treat the exhaust gas, thereby realizing the recycling of the treated liquid.
