Problems solved by technology

[0002] At present, for the pyrolysis disposal and utilization of organic solid waste, positive pressure and high temperature processes are generally used, such as waste plastics, organic solid waste of domestic garbage, and biomass raw materials for pyrolysis. Due to the low bulk density of these materials, they are generally less than 200 kg / m3, using a conventional screw conveyor to feed, the filling factor of the material is less than 0.5, oil and gas leakage occurs in the positive pressure operation of the reactor; the bulk density of the material is small, and the feeding is often interrupted due to material bridging and arching, which seriously affects the barrier Pyrolysis process implementation of organic solid waste
