  • System for urban organic solid waste pyrolysis-gasification coupled with drying
    Patent number: 11352284
    Abstract: A system for urban organic solid waste pyrolysis-gasification coupled with drying includes a sludge feeding and storage device, a pre-drying device, a cyclone separator, a specific cloth bag for sludge and a flue gas waste heat recovery device sequentially connected. The cyclone separator and a sludge outlet of the specific cloth bag for sludge are connected with a cyclone fluidized bed gasification furnace. The cyclone fluidized bed gasification furnace is connected with a high-temperature separator. The high-temperature separator is connected with a secondary combustion chamber. High-temperature flue gas generated by the secondary combustion chamber serves as a heat source of the pre-drying device. Ash generated by the high-temperature separator and secondary combustion chamber is sent to an ash bin after being cooled by a cold slag conveyor.
