With the continuous improvement of environmental awareness, the research of waste gas treatment equipment has also attracted more and more attention. Waste gas treatment equipment is a device used to purify industrial waste gas, which can effectively remove harmful substances in the waste gas, reduce pollutant emissions, and protect the environment and human health.

At present, the research of waste gas treatment equipment is developing in the direction of high efficiency, energy saving and environmental protection, mainly including the progress in the following aspects:

First, adsorption treatment technology

Adsorption treatment technology is a method to remove the pollutants in the exhaust gas after adsorption on the surface of the adsorbent. In recent years, more and more researchers have begun to pay attention to the application of nanomaterials in the adsorption and removal of waste gas pollutants. Nanomaterials have high specific surface area, high porosity and special surface activity, which can significantly improve the adsorption efficiency of waste gas pollutants and the effect of waste gas treatment. In addition, the research and development of new adsorbents and the development of catalysts and adsorbents complexes have also become the research focus of adsorption treatment technology.

Second, catalytic oxidation technology

Catalytic oxidation technology is to make the pollutants in the waste gas through the action of the catalyst, so that it is oxidized and decomposed at a lower temperature, so as to achieve the purpose of purifying the waste gas. In recent years, some new catalysts such as activated carbon, metal oxides, composite catalysts have been widely studied and applied. In addition, new technologies such as nano-iron and hydrogen reduction catalysis also have good application prospects.

Third, plasma technology

Plasma technology is a method of using plasma to form a hollow electrode plasma field to treat the waste gas, using charged particles to dissociate and oxidize the harmful components in the waste gas, so as to achieve the purpose of removing the waste gas pollutants. In recent years, the research focus of plasma technology is mainly focused on high efficiency, low energy consumption, environmental protection, etc., and the application of the structure and materials of new plasma generators has been explored.

4. Biological treatment technology

Biological treatment technology is a method of using microorganisms to remove harmful components in waste gas, which is widely used in anaerobic and aerobic fields. Biological treatment technology has great potential in waste gas treatment, and can achieve the purpose of high efficiency, energy saving and environmental protection. At present, researchers mainly focus on the influence of various microbial cell strains, culture conditions and other factors on biological treatment, as well as the help of new catalysts and nanomaterials on biological treatment systems.

In summary, the current research on waste gas treatment equipment has begun to develop in the direction of high efficiency, low cost and environmental protection, and the research and development and application of various new technologies and devices will bring better purification effects and make important contributions to the realization of "green environmental protection".
