Air pollution is one of the most prominent environmental problems in my country. Industrial waste gas is an important source of air pollutants. A large amount of industrial waste gas is discharged into the atmosphere, which will inevitably reduce the quality of the atmospheric environment, bring serious harm to human health, and cause huge losses to the national economy. Harmful substances in industrial waste gas enter the human body through the respiratory tract and skin, and can cause temporary and permanent lesions to human breathing, blood, liver and other systems and organs, especially benzopyrene polycyclic aromatic hydrocarbons can cause the human body to directly cause cancer. Human beings highly value it. Industrial waste gas includes organic waste gas and inorganic waste gas. Organic waste gas mainly includes various hydrocarbons, alcohols, aldehydes, acids, ketones and amines, etc.; inorganic waste gas mainly includes sulfur oxides, nitrogen oxides, carbon oxides, halogens and their compounds. Industrial waste gas has different treatment methods according to its exhaust air volume, temperature, concentration and its own chemical and physical properties.

Hongkai Company now introduces several exhaust gas treatment plans:　　

1. Zeolite concentration + direct-fired incineration system, which is suitable for large air volume and low concentration organic waste gas smelting, and is now widely used in spraying waste gas treatment, the best choice for safety, energy saving and environmental protection. The system mainly consists of pretreatment system, zeolite concentration runner, combustion type incinerator, fan, chimney, etc.

2. Activated carbon adsorption + catalytic combustion system is most suitable for low-concentration organic waste gas that is not suitable for direct combustion or catalytic combustion, especially for large air volume treatment sites, which can obtain satisfactory economic and social benefits.

3. Catalytic combustion system: Organic waste gas is oxidized through a catalyst at a certain temperature (250-400°C) to generate carbon dioxide and water to achieve the purpose of exhaust gas purification. It is widely used in various places where organic waste gas is generated such as painting, electronics, printing, etc. It can be used directly with various drying ovens, tunnel kilns and other baking equipment. It can effectively eliminate various organic gases such as benzene, phenol, aldehyde, ester, etc., and the purification efficiency is greater than 97%.

4. Direct-fired incineration system: It is suitable for the treatment of various organic pollutants, such as highly viscous organic pollutants, and catalyst poisoning pollutants caused by catalytic combustion (especially organic pollutants produced by cathodic electrophoresis or high viscosity Molecular organic matter). Direct-fired waste gas incinerators are mainly used for the purification of triphenyl, phenol, aldehydes, fats, ketones and other harmful waste gas produced in automobiles manufacturing, chemical plastics, coating and other industries by direct combustion to meet environmental protection requirements. 

With many years of exhaust gas purification experience, the company has various coating exhaust gas treatment equipment products.
