Title:
SOLID WASTE TREATMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/032801
Kind Code:
A1
Abstract:
A solid waste treatment system, comprising a dryer (10), a pyrolysis reactor (20) and a pyrolysis product treatment system. The dryer (10) is used for drying solid waste. The pyrolysis reactor (20) is connected to the dryer (10) and is used for carrying out an oxygen-free pyrolysis treatment on dried solid waste to generate solid waste residue and pyrolysis gas. The pyrolysis product treatment system comprises a solid waste residue recovery unit and a gas-phase treatment unit, which are connected to the pyrolysis reactor (20). The gas-phase treatment unit comprises a dust remover (40), a condenser (42) and a gas-liquid separator (43). The dust remover (41) is connected to the pyrolysis reactor (20) and is used for removing dust from the pyrolysis gas. The dust remover (41) is connected to the dryer (10), so as to recycle waste heat of pyrolysis gas subjected to dust removal to the dryer (10). The condenser (42) is connected to the dryer (10) and is used for cooling pyrolysis gas used by the dryer (10). The gas-liquid separator (43) is connected to the condenser (42) and the dryer (10) and is used for carrying out gas-liquid separation on the cooled pyrolysis gas and/or on the pyrolysis gas used by the dryer (10). The solid waste treatment system can reduce the amount of solid waste, reduce pollution and reduce energy consumption.
