NOVELTY - Integrated fast carbonization of municipal waste comprises preprocessing the municipal waste by sorting the waste including rock, metal, coal and glass, crushing by a crusher, transferring into a drying furnace, where the waste is heated rapidly by an infrared heating cover for rapid dehydration, vaporizing, conveying the tail gas into a tail gas processing work station, passing hot air, crushing and mixing, passing high-temperature gas, crushing, dehydrating, carrying out pyrolysis, conveying the high temperature gas generated in pyrolysis into a carbonization furnace and carbonizing.    USE - The method is useful for integrated fast carbonization of municipal waste (claimed).    ADVANTAGE - The method: ensures that there is no escape or emission of waste gas; has high heat energy utilization rate; and treats large amount of waste.    DETAILED DESCRIPTION - Integrated fast carbonization of municipal waste comprises (a) preprocessing the municipal waste, sorting the waste including rock, metal, coal and glass, recovering, crushing by a crusher until a granularity of 5-50 mm, (b) transferring the crushed waste into cloth storage bin of a drying furnace, uniformly distributing the waste from cloth material to a drying furnace via a conveyor belt, conveying the waste into a spiral conveying machine, where the waste is heated rapidly by an infrared heating cover for rapid dehydration, vaporizing the water in the waste, conveying the tail gas into a tail gas processing work station via a suction fan, and conveying the dehydrated waste into a screw conveyor and transferring to a warehouse, (c) passing hot air into the warehouse via hot air pipes at the bottom of the warehouse, again crushing and mixing the raw materials by passing hot air in a spiral stirrer, crushing and drying, feeding into a powder feeding machine, and bubbling the waste into a chamber A and chamber B from the roots blower through a three-way valve, (d) passing hot air into bottom of the chamber A and B via hot air pipelines, crushing and mixing and hot air drying, where the tail gas after being filtered via a filter is discharged into tail gas treatment work station, (e) conveying the wastes from the chambers A and B into a drying chamber A and drying chamber B, passing high-temperature gas, stirring by an inner spiral helical stirrer for four times, crushing, mixing with high temperature gas, dehydrating, drying to generate gas, which is blown to tail gas processing station via a draught fan, (f) conveying the dried waste from the drying chambers A and B into pyrolysis furnaces A and B, carrying out pyrolysis of the waste under oxygen atmosphere, conveying the pyrolysis gas into a burner for combustion to produce more than 550 degrees C hot air, circulating the hot air into the pyrolysis furnace to heat the pyrolysis furnace, and (g) conveying the high temperature gas generated after pyrolysis of the waste into a carbonization furnace, infrared heating the furnace, carbonizing to obtain carbonized product, separating the non-carbonized product at the bottom of the furnace by a rotating sieve, and discharging via a different pipeline, where the furnace top part is set with a heat exchanger, the heat exchanger is connected to an air blower, and the air blower blow air into a heat exchanger fro high temperature gas heat exchanging process to recycle the heat in the drying chambers A and B.
