Among the above-mentioned methods for treating used tires, pyrolysis is considered as one of the most efficient and environmentally friendly treatment methods. The pyrolysis is to heat the rubber blocks of the waste tires at high temperature under the condition of air isolation to decompose fuel gas (hydrogen, methane and the like), oil, carbon black, steel wires and the like, so that the waste tires can be recycled without secondary pollution. The products of pyrolysis of waste tires include pyrolysis oil, pyrolysis gas and pyrolysis carbon black. Although the domestic waste tire pyrolysis production line is put into use, the following two problems exist in most cases: 1) most of the pyrolysis gas is used as pyrolysis fuel, and the surplus heat pyrolysis gas is directly discharged or is led to a waste gas combustion chamber to be combusted and then discharged outside, so that resource waste and certain pollution are caused; 2) the tail gas treatment process is single, and the emission requirements of national petrochemical industry pollutant emission standards and foul pollutant emission standards are difficult to meet.
