The "three modernizations" (reduction, harmless, and resourceful) treatment of municipal solid waste must be the trend. At present, the most mature and effective method in the world is waste incineration, but waste incineration will produce secondary pollution. Others The disadvantages of his implementation lead to a lot of controversy.

After the domestic waste reacts in the pyrolysis furnace, it will produce high-temperature tail gas. In the process of tail gas treatment, it is usually discharged directly after simple treatment, which can easily cause secondary pollution of the environment and damage the surrounding ecological environment.

In addition, some factories will produce some exhaust gas during the industrial production process. Most of these exhaust gases are harmful, and most of them are discharged directly into the atmosphere through high chimneys, causing great damage to the surrounding ecology; it is not in line with modern society. Requirements for energy saving and emission reduction.

Therefore, it is a relatively important subject for the treatment of exhaust gas from waste incineration and industrial production. The zero discharge of tail gas treatment is an important goal of tail gas treatment.
