A spray pipe 16 is fixedly connected to the middle position, and the spray pipe 16 is connected to the output end of the water pipe 6. Multiple spray heads 17 are fixedly connected to the spray pipe 16. The absorbent is transported into the spray pipe 16 through the water pipe 6, and then evenly sprayed out through the spray heads 17, effectively removing impurities and harmful substances in the flue gas and improving the flue gas treatment effect. An activated carbon regeneration box 4 is set on the other side of the flue gas treatment chamber 1. An activated carbon adsorption layer 13 is set inside the activated carbon regeneration box 4. The activated carbon can effectively adsorb harmful substances in the flue gas. Multiple heating tubes 12 are evenly arranged on the inner wall of the box around the activated carbon adsorption layer 13. A power supply 5 is fixedly connected to the top of the activated carbon regeneration box 4, and the power supply 5 is electrically connected to the heating tubes 12. When the power supply 5 is turned on, the heating tubes 12 can heat the activated carbon in the activated carbon adsorption layer 13 at high temperature. After the activated carbon is saturated by long-term use, the adsorbate adsorbed on the activated carbon is removed by high temperature heating, restoring its adsorption performance, thereby achieving the purpose of reuse and reducing operating costs.
[0033] A flue gas inlet pipe 11 is fixedly connected to one side of the activated carbon regeneration box 4 near the bottom. The flue gas inlet pipe 11 is used to transport flue gas into the activated carbon regeneration box 4. A flue gas pipe 3 is fixedly connected to the other side of the activated carbon regeneration box 4 near the top.

The flue gas then passes through the desulfurization layer 15 to remove sulfur dioxide from the flue gas. Finally, the flue gas after multiple layers of filtration is discharged through the top of the flue gas treatment chamber 1.
