waste gas treatment

Waste gas is generally treated after purification and then discharged.

Flue gas purification mainly refers to the treatment of industrial waste gas produced in industrial places, such as dust particles, smoke and dust, malodorous gases, toxic and harmful gases, etc. Common waste gas purification includes factory dust waste gas purification, workshop dust waste gas purification, organic waste gas purification, waste gas odor purification, acid-base waste gas purification, chemical waste gas purification and so on.

The waste gas discharged from industrial production often has harmful effects on the environment and human health. Before being discharged into the atmosphere, purification measures should be taken to make it meet the requirements of waste gas emission standards. This process is called exhaust gas purification. Commonly used waste gas purification methods are: absorption method, adsorption method, condensation method and combustion method, in addition to some dirty adobe houses.

Introduction of important purification tools

Chimney is an important exhaust device of purification system. Because the purified gas still contains a certain concentration of pollutants, these pollutants diffuse and dilute in the atmosphere after being discharged from the chimney, and finally settle to the ground. In order to ensure that the ground pollutant concentration does not exceed the ambient air quality standard, the chimney must have a certain height, and the specifications are also very important.

In addition, in order to ensure the normal operation of the exhaust gas purification system, necessary auxiliary equipment is often added to the purification system according to the different purification objects. For example, the cooling device and waste heat utilization device when dealing with high-temperature gas, the pipeline compensator to meet the expansion and contraction changes of steel, the explosion-proof device when transporting flammable and explosive gas, and the air volume and pressure balance of the system.
