Description

Technical Field

[0002] Acid-base waste gas treatment is a technical process in the field of environmental protection used to reduce and eliminate acidic or alkaline harmful gases emitted during industrial production. If these waste gases are directly discharged without treatment, they will have a serious impact on the environment and human health.

[0003] At present, the spray tower treatment method is usually used. After the exhaust gas enters the spray tower, it will be in countercurrent contact with the absorption liquid sprayed in the spray tower. The filler can make the harmful substances in the exhaust gas fully contact with the absorption liquid, and the acid-base neutralization reaction can be achieved. The harmful substances in the exhaust gas can be removed and the purpose of purifying the exhaust gas is achieved. However, in the process of spraying the absorption liquid, since the absorption liquid is recycled, the filler is easy to enter the water tank, causing the water tank to be blocked, affecting the use of the water pump.

[0004] In summary, there is an urgent need for a spray tower for treating acid-base waste gas that can intercept fillers to solve the above problems. Utility Model Content
