Down suction type radiation tube biomass pyrolysis carbonizing furnace

Abstract

The invention provides a down suction type radiation tube biomass pyrolysis carbonizing furnace which comprises a furnace body used for pyrolysis carbonizing. A filling machine used for filling raw materials in a raw material bin is disposed between the raw material bin and the top of the furnace body, heat accumulated type radiation tube burners used for performing biomass pyrolysis on the raw materials entering the furnace body are evenly disposed on the furnace body, a gas collecting port used for collecting gas products and a carbon exit used for outputting carbon products are respectively arranged at the lower end of the furnace body, the carbon exit is connected with a carbon conveyor used for conveying the carbon products out of the furnace body, the gas collecting port is connected with a heat exchanger through a gas pipeline, the heat exchanger is connected with a bag-type dust collector used for dedusting cooled gas, the bag-type dust collector is connected with a gas storage tank through a draught fan, and the gas storage tank is used for storing the gas products. Biomass gasification is performed by the aid of the heat accumulated type radiation tube burners, comprehensive heat efficiency is high, requirement for material size is less strict, and continuous gasification can be achieved.

Description

technical field [0001] The invention relates to a pyrolysis charcoal furnace, in particular to a downdraft radiant tube biomass pyrolysis charcoal furnace. Background technique [0002] Biomass resources have the characteristics of a wide range of sources, easy centralized treatment, low pollution, and renewable, and have great application potential. According to statistics, my country's crop straw alone has a total resource of more than 700 million tons. However, about 33-40% of them are abandoned in the field or burned in the open air, which not only causes a serious waste of biomass resources, destroys the soil structure, reduces production capacity, but also causes serious environmental pollution, threatening transportation and people. production and life safety. Preparation of these waste biomass resources into biochar by carbonization technology for diversified development and utilization can largely solve complex problems faced in the fields of sustainable developme...
