SOLID CARBON-CONTAINING WASTE PYROLYSIS UTILIZATION METHOD AND WASTE TREATMENT SYSTEM FOR ITS IMPLEMENTATION

摘要

FIELD: processing and recycling wastes; technological processes.;SUBSTANCE: invention relates to the field of the carbon-containing materials thermal processing and is intended for the solid municipal waste utilization. Waste processing system comprises pyrolysis unit including at least two pyrolysis units, prepared waste to the reactors supplying conveyor line, carbonaceous residue into the receiving hopper transporting conveyor line. In the drum reactor (13), the cylindrical combustion chamber (14) is arranged coaxially and is coupled with the reactor working volume internal heating circuit. Near the reactor cylinder inner wall along its entire length auger conveyor (16) is located, under reactor the auger conveyor-cooler (23) is located. Thermal effect on the prepared waste is carried out consistently in two stages: first, removing the surface (capillary) water at temperature of 120–150 °C, and then applying thermal destruction in the temperature range 200–450 °C with the raw materials in the drum reactor (13) continuous stirring. Separating the steam-gas mixture into water and fuel fractions.;EFFECT: enabling increase in the thermal destruction efficiency at low pyrolysis temperatures, increase in the reactors specific productivity, and reduction in energy costs.;2 cl, 3 dwg
