Embodiment Construction
[0022] The invention provides a method for treating styrene waste gas. The method mainly includes the following steps: making countercurrent contact between styrene waste gas and an alkaline solution of potassium permanganate, and during the contact process, the alkaline solution of styrene and potassium permanganate Oxidation reaction occurs, and after the reaction is completed, the exhaust gas that consumes styrene is discharged into the atmosphere.
[0023] Specifically, the styrene waste gas and the alkaline solution of potassium permanganate can be countercurrently contacted in the absorption tower, and the inside of the absorption tower is provided with a packing layer. Styrene waste gas enters the absorption tower from the bottom of the absorption tower, and the alkaline solution of potassium permanganate enters the absorption tower from the top of the absorption tower. In the packing layer of the absorption tower, the alkaline solution of styrene waste gas and potassium...
