The invention relates to a low dioxin emission
system and method for high-temperature
carbonization pyrolysis and high-temperature gasification
incineration of
medical waste. The
system comprises a
dry distillation bar making
system and a high-temperature gasification purifying system. The
dry distillation bar making system comprises a storage warehouse, a
carbonization furnace, a bar making
machine, a warehouse, a purifying device, a
waste heat boiler and a
combustion chamber.
Solid waste is brought out of the storage warehouse and then thrown into the
carbonization furnace, and after carbonization, solids and oil
tar are removed out and conveyed to the bar making
machine to serve as raw materials. The carbonization furnace is connected with the
combustion chamber and the purifying device. The purifying device is connected with the
waste heat boiler. The high-temperature gasification purifying system comprises a draught fan, a gasification furnace, a
waste heat boiler, a
quenching tower, a dioxin removing
tower, a
cyclone mixing adsorption device, dust collecting bags, an induced draught fan and the like, wherein the draught fan, the gasification furnace, the waste heat boiler, the
quenching tower, the dioxin removing tower, the
cyclone mixing adsorption device, the dust collecting bags, the induced draught fan and a
chimney are sequentially connected. By means of the system and method, emission of dangerous waste and
medical waste can be effectively controlled, and harmlessness, reduction and reclamation are achieved.
