Description

technical field [0001] The invention relates to a result-controllable organic waste gas catalytic combustion treatment device, which belongs to the field of waste gas treatment. Background technique [0002] Catalytic combustion is the use of catalysts at low temperatures (200-400°C) to achieve complete oxidation of organic matter. Therefore, it consumes less energy, is easy to operate, is safe, and has high purification efficiency. In terms of purification, such as chemical industry, spray paint, insulating materials, enameled wire, paint production and other industries are widely used, because the catalysts for the catalytic combustion of organic matter are mostly noble metal (mainly platinum and palladium) catalysts. However, due to the high price of noble metal catalysts and the lack of resources, the research on new and more economical catalysts has become a new development direction; in addition, the exhaust gas after catalytic combustion, in some cases, due to the hig...

Problems solved by technology

However, due to the high price of noble metal catalysts and the lack of resources, the research on new and more economical catalysts has become a new development direction; in addition, the exhaust gas after catalytic combustion, in some cases, due to the high concentration of organic matter, the catalyst is aging, or The incomplete reaction caused by insufficient reaction temperature and other reasons will often cause more organic matter to remain in the gas after combustion, so the gas after primary combustion is often unable to meet the atmospheric emission standards
