Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to a catalytic combustion treatment device for organic waste gas. Background Technology

[0002] Organic waste gas refers to industrial waste gas containing volatile organic compounds or other organic pollutants, mainly originating from industries such as chemical processing, petroleum refining, coating, printing, pharmaceuticals, and furniture manufacturing. If this type of waste gas is emitted directly without treatment, it will cause serious harm to the environment and human health, such as leading to ozone layer depletion, photochemical smog, PM2.5 formation, and even carcinogenic risks.

[0003] Common treatment technologies for organic waste gas include physical adsorption, thermal combustion, catalytic combustion, biological treatment, plasma technology, and condensation recovery. The principle of catalytic combustion is the low-temperature (200-400℃) oxidation and decomposition of VOCs under the action of a catalyst (such as platinum or palladium). Existing catalytic combustion equipment for organic waste gas treatment introduces the waste gas into a combustion chamber to contact the catalyst for catalytic combustion. However, catalytic combustion is suitable for medium- to high-concentration waste gas; directly introducing waste gas into the combustion chamber results in excessively high concentrations, which affects the catalytic combustion of the organic waste gas.

[0004] In view of this, we propose a catalytic combustion treatment device for organic waste gas. Utility Model Content
