Device for produce complete alternation low temperature pyrolysis of blue charcoal

The utility model provides a device for produce complete alternation low temperature pyrolysis of blue charcoal, wherein, by raw coal warehouse, complete alternation gas retort, the dry distillation system of arranging burnt device component is with former pyrolysis of coal for blue charcoal, including the coal gas of tar, by the pneumatic trough, within a definite time cold ware, electrical tar precipitator, the desulfurizing tower, the coal gas clean system that the air-blower is formed will purify and the cooling including the gas washing of coal tar, condensate separation that tar aqueous ammonia piece-rate system produced in with coal gas clean system is tar sediment, coal tar and the aqueous ammonia, the gas heating system utilizes tar sediment that tar aqueous ammonia piece-rate system produced and the coal gas after the heat transfer as fuel hot gas heating to the required dry distillation temperature of raw materials coal that will circulate. The utility model discloses can realize low rotten bituminous coal dry distillation, the gas purifying, the drawback that present technology used air burning coal gas to provide the dry distillation institute calorific requirement waste gas gauge height that the process is brought has been overcome to the function of retrieving coal tar, makes the caloric power of gas rise, be convenient for follow-up gas purifying and processing utilization
