[0043] 1) The exhaust gas from the paint booth enters the heat exchanger through the intake pipe under the action of the booster pump, and then sprays it into the reaction liquid of the exhaust gas treatment device in the paint booth through the nozzle, and the exhaust gas treated by the reaction liquid is further adsorbed by the adsorption layer Finally, it is discharged through the outlet pipe. After the above process is carried out for 1 hour, the treatment of the exhaust gas in the paint room is completed.
[0044] 2) In the above-mentioned step 1), the reaction solution of the waste gas treatment device in the paint baking room contains catalyst and H 2 o 2 Aqueous solution, wherein the catalyst is Cu-Mn-Ce-O catalyst.
[0045] 3) In the above step 1), the content of the Cu-Mn-Ce-O catalyst in the reaction solution of the paint booth waste gas treatment device is 0.025% (mass percentage).
[0046] 4) In the above step 1), the H in the reaction solution of the waste gas ...
