Description
technical field [0001] The invention relates to an incineration treatment device. Background technique [0002] At present, a large amount of organic waste gas and waste liquid will be produced in the production process of the main device in the domestic organosilicon industry. These untreated organosilicon chlorides are flammable in case of fire, hydrolyzed in case of water, and emit a large amount of hydrogen chloride gas, leaving white solid residues. Hydrogen chloride gas is highly corrosive and is extremely harmful to human body and the environment. At home and abroad, the incineration method is mostly used for this kind of waste gas and waste liquid. Among them, Patent No. CN 201010522959 discloses the combustion treatment process of chlorosilane-containing waste gas and waste liquid in polysilicon production, and Patent No. CN 109654515 A discloses an environmental protection treatment system for organic silicon chlorine-containing organic waste gas and waste liquid...
