Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a catalytic incinerator. Background Art

[0002] Direct emission of volatile organic waste gas will pollute the environment and cause great harm to human health, so it needs to be treated to reduce the VOC content.

[0003] At present, the main methods for treating volatile organic waste gas include active adsorption method, induced draft high-altitude emission method, combustion treatment method, absorption degassing method, condensation collection method, biological treatment method, etc. Among them, the combustion treatment method is mainly based on the fact that VOCs are organic volatile substances and are easy to burn. The use of room temperature or catalytic oxidation combustion treatment can convert VOCs into carbon dioxide and water. The catalytic incineration in the combustion treatment method can use catalysts to change the chemical reaction pathway and reduce the activation energy required for the combustion reaction, thereby accelerating the reaction rate and reducing the reaction temperature, which is more energy-efficient. The catalyst components in the existing catalytic incinerator are very troublesome to replace or repair. Utility Model Content
