High -efficient domestic waste incineration disposal system of small -size energy -conservation

The utility model relates to a high -efficient domestic waste incineration disposal system of small -size energy -conservation, including burning preprocessing system, the system of burning, flue gaswaste heat utilization equipment and flue gas processing system. Flue gas processing system includes that first gas -liquid heat exchange device, first draught fan, surplus soda ash utilize tower, semidry method deacidification tower, second gas -liquid heat exchange device, cooling tower, cyclone, bag collector, second draught fan and chimney. This system optimization msw incineration preprocessing system, burn burning furnace inner structure and flue gas processing system, taken all factors into consideration the broken convenience with the dehydration of rubbish, improve the gas tightness of burning burning furnace, promote that rubbish fully burns, reduce secondary pollutant and produce, make full use of flue gas waste heat, reutilization utilize the soda ash, get rid of pollutants such as acid gas, msw incine
