Description

Technical field [0001] The invention relates to a pyrolysis catalytic cone rotating reaction kettle for polymer waste. Background technique [0002] Organic polymer solid waste refers to waste plastics, waste rubber and waste tires contained in domestic waste. The treatment of domestic garbage generally adopts several methods such as scientific landfill, incineration, sorting and utilization, and pyrolysis. Landfill occupies a large amount of land, and the direct landfill of original ecological waste seriously pollutes the environment, and the cost of scientific landfill is high; incineration is a technically mature treatment method, and the excess air coefficient of incineration is greater than 1, and the gas emissions are large. A large amount of Nox gas, hexavalent Cr, dioxins and other heavy metal oxides are produced, the processing cost is high, and the public reaction is strong. [0003] Pyrolysis is the pyrolysis of organic polymer waste under the isolation of air, break...
