NOVELTY - A garbage gasifying system comprises plasma gasifying furnace (1), carbon dioxide air seal feeding device, heat exchanger (6), draught fan (8) and whirlwind separator (10). The carbon dioxide air seal feeding device includes carbon dioxide air seal device (3) and spiral feeder (4) connected with transmitting port. The themolysis air outlet of plasma gasifying furnace is connected to carbonation reaction chamber on heat exchanger by a connecting pipe. The gas outlet of whirlwind separator is connected to the air suction of draught fan.    USE - Garbage gasifying system using calcium oxide and plasma gasification for processing solid organic waste.    ADVANTAGE - The system can process garbage (e.g., medical and industrial macromolecular waste) without exhaust and pollution.    DETAILED DESCRIPTION - Garbage gasifying system comprises plasma gasifying furnace (1), carbon dioxide air seal feeding device, heat exchanger (6), draught fan (8) and whirlwind separator (10). The carbon dioxide air seal feeding device includes carbon dioxide air seal device (3) and spiral feeder (4) connected with transmitting port. The discharge port of spiral feeder is connected to feed port of plasma gasifying furnace by S-shaped connecting pipe (2). The themolysis air outlet of plasma gasifying furnace is connected to carbonation reaction chamber on heat exchanger by a connecting pipe. The carbonation reaction chamber is connected with thermal exchanger. The hot carrier outlet of heat exchanger is connected to hot carrier inlet of plasma gasifying furnace and gas-solid mixture input port of whirlwind separator. The gas outlet of whirlwind separator is connected to the air suction of draught fan. The air outlet of draught fan is connected to themolysis air inlet of heat exchanger. The themolysis air outlet of heat exchanger is connected to themolysis air input interface of the plasma gasifying furnace. The solid outlet of whirlwind separator is connected with calcium oxide spraying gun by calcium oxide transmitting pipe. The nozzle of calcium oxide spraying gun extends in carbonation reaction chamber. The carbon dioxide input interface is adjacent to the calcium oxide spraying gun. The synthetic air outlet of plasma gasifying furnace is jointed with the joint part of themolysis area and gasifying area.    An INDEPENDENT CLAIM is included for a garbage gasifying device.
