AOX combustion furnace is mainly used to treat waste gas or wastewater containing organic halogens, especially in the production process of chemical, pharmaceutical and other industries, where the waste gas often contains difficult to decompose organic halogen compounds. AOX compounds refer to organic halides that can be adsorbed and often pose significant risks to the environment and human health. Therefore, they must be effectively treated through appropriate technological means.

1、 Technical principles

　　AOX combustion furnaceThe basic working principle is to convert organic halogen compounds into harmless substances through high-temperature oxidation reactions. The principle can be summarized as follows:

1. Pre treatment stage: The exhaust gas or wastewater is first treated by corresponding pre-treatment devices to reduce the concentration of organic halogen compounds, ensuring that the temperature and flow rate of the exhaust gas or wastewater entering the combustion furnace are suitable for subsequent treatment.

2. High temperature combustion: After the exhaust gas enters the high-temperature environment of the combustion chamber, these organic halogen compounds undergo high-temperature oxidation reactions in the presence of sufficient oxygen. At this point, hydrocarbons are oxidized to carbon dioxide, while halogen elements react with oxygen to form halogen oxides such as chlorine gas (Cl2).

3. Purification and emission: After combustion treatment, most of the harmful substances in the exhaust gas have been decomposed or converted into harmless substances, and the remaining small amount of gas is discharged after being treated by cooling and adsorption systems. For wastewater treatment, it is usually necessary to further purify it through subsequent treatment equipment such as gas-liquid separators.

The key technology lies in the ability to effectively decompose organic halogen compounds in high-temperature environments and control their emissions to meet environmental requirements. In addition, the furnace design must have good heat exchange effect and efficient combustion efficiency to ensure the rational utilization of resources and control of processing costs.

2、 Application analysis

AOX combustion furnaces are mainly used in the following fields:

1. Chemical industry: Many products in the chemical industry produce waste gases containing organic halogens during the production process, such as polymers, pesticides, dyes, solvents, etc. In these production processes, the exhaust gas often contains a certain concentration of AOX compounds. If discharged directly without treatment, it will cause serious pollution to the environment. Therefore, it is one of the important equipment for waste gas treatment in chemical enterprises.

2. Pharmaceutical industry: During the pharmaceutical process, some raw materials and by-products of synthetic drugs may contain organic halogens, which must be treated to ensure that production waste gas or wastewater meets emission standards. Therefore, it is widely used in the treatment of exhaust gas and wastewater in pharmaceutical factories.

3. Electronics industry: In the production process of electronic components, some solvents and chemicals may contain organic halogen substances. For example, during the surface treatment of electronic components and the production of plastic packaging, halogen containing exhaust gases are generated. It can also effectively treat these halogenated waste gases and prevent pollution.

4. Petrochemical and refining industries: During the petroleum refining process, some waste gas or wastewater containing AOX may also be generated. For example, certain dechlorination processes in petroleum refining and chlorides in fuels require treatment through use. Not only can it effectively decompose AOX compounds, but it can also prevent these chemicals from entering the environment.

With the continuous improvement of environmental protection requirements, various industries must adopt effective waste gas and wastewater treatment methods in the production process. AOX combustion furnace has become an important equipment for treating waste gas or wastewater containing organic halogens due to its efficient processing capacity and wide application fields. Through the principle of high-temperature oxidation, harmful AOX compounds can be effectively decomposed, reducing environmental pollution and providing technical support for the sustainable development of the industry.
