[0035] Working principle and use process of the utility model: In this scheme, a waste heat utilization box 2 is arranged inside the waste gas treatment box 1, and the waste heat of the high-temperature waste gas can be introduced into the waste heat utilization box 2 through the waste heat guide pipe 4, and the high-temperature waste gas flows back into the waste heat heat conduction component 3, and the heat is conducted by the waste heat heat conduction component 3, and heat exchange is performed in the waste heat utilization box 2, and the waste heat is used to heat the water source in the waste heat utilization box 2, so as to achieve the waste heat utilization effect, avoid the heat energy waste caused by the direct discharge of the waste heat, and the energy saving effect is relatively good;

[0036] After the waste heat is discharged from the waste heat heat conducting component 3, the waste gas can be introduced into the circulating spray component 5 by the waste gas cleaning component 7. After the discharged waste gas is mixed and cleaned by the waste gas cleaning component 7 with the water source, it is then atomized and sprayed by the circulating spray component 5, which has a good treatment effect on the waste gas, neutralizes and settles the harmful substances in the waste gas. After the waste gas is discharged, it can be quickly discharged by the particle adsorption component 6. While being discharged by the particle adsorption component 6, the particles and harmful substances in the waste gas can be adsorbed and separated, and the waste gas treatment effect is relatively excellent;
