Among the above methods for treating junked tires, pyrolysis is considered to be the most efficient and environmentally friendly treatment method. Pyrolysis refers to heating the rubber blocks of the waste tires at high temperature under the condition of isolating air, so that the rubber blocks decompose fuel gas (hydrogen, methane and the like), oil, carbon black, steel wires and the like, and the waste tires can be recycled without secondary pollution. The products of the pyrolysis of the waste tires comprise pyrolysis oil, pyrolysis gas and pyrolysis carbon black. Although the existing domestic waste tire pyrolysis production line is used, most of the problems are that 1) most of pyrolysis gas is used as pyrolysis fuel, and the pyrolysis gas is directly discharged or led to an exhaust gas combustion chamber for combustion and then discharged, so that resource waste and certain pollution are caused, and 2) the tail gas treatment process is single, and the emission requirements of national emission standards of pollutants in petrochemical industry and malodorous pollutants are difficult to be met.
On the other hand, the waste incineration power generation is an environment-friendly and efficient urban solid waste treatment method, but the waste incineration power generation has some problems in the development process.
