[0024] As Figure 1 , Figure 2 and Figure 3As shown, the metal infusion pipe 17 is sealed with a sealing sleeve at the connection with the waste gas treatment tower 3 to prevent water treatment. When the waste gas strengthening treatment device 6 is used, the sealing cover 18 at the right end of the metal infusion pipe 17 needs to be opened, and the organic mixed solvent is injected into the flat circular liquid spraying disc 16 through the metal infusion pipe 17. The organic mixed solvent is a mixture of alcohol, ketone and ether organic solvents. The flat circular liquid spraying disc 16 sprays the organic mixed solvent into the thickened adsorption sponge 14, so that the thickened adsorption sponge 14 is filled with a large amount of organic mixed solvent. After the injection is completed, the sealing cover 18 is closed to ensure good sealing and prevent waste gas leakage and solvent evaporation. When the 2-ethylanthraquinone waste gas enters from the waste gas inlet 2 at the bottom left end of the waste gas treatment tower 3, the waste gas first reaches the position of the metal fixing cylinder 11.

The uniformly distributed waste gas enters the area of the metal placing net 13 and the thickened adsorption sponge 14, and passes through the air holes 15 densely distributed in the thickened adsorption sponge 14. At this time, the flat circular liquid spraying disc 16 uniformly sprays the organic mixed solvent into the thickened adsorption sponge 14 through the bottom-end densely distributed liquid spraying holes. The waste gas is in full contact with the organic mixed solvent in the thickened adsorption sponge 14 in the process of passing through the air holes 15. The organic mixed solvent has an adsorption effect on the harmful substances in the waste gas. The thickened adsorption sponge 14 has a porous structure and a large specific surface area, which can increase the contact area with the waste gas and improve the adsorption capacity. The organic mixed solvent sprayed in the thickened adsorption sponge 14 has physical or chemical adsorption effect with the harmful substances in the waste gas, thereby removing part of the harmful substances in the waste gas. The arrangement of the air holes 15 enables the waste gas to normally enter and exit the thickened adsorption sponge 14, and also increases the contact time and contact area of the waste gas with the adsorption medium.
