Biomass material carbonization and activation integrated device

Abstract

The invention relates to a biomass material carbonization-activation integrated device, and overcomes the problems of carbonization-activation devices at present, namely a low efficiency, controlling difficulty of activation processes and high energy consumption. The device comprises a vertical carbonization furnace and a horizontal activation furnace. A vertical carbonization cylinder is disposed in the carbonization furnace. An activation spiral conveyer transversally penetrates the activation furnace. The lower end of the carbonization cylinder is connected to the initial end of the activation spiral conveyer. The carbonization furnace is also provided with steam spraying tubes communicating with the activation spiral conveyer and spraying steam to the inside of the activation spiral conveyer. The steam spraying tubes penetrate the furnace wall of the carbonization furnace. Both the activation furnace and the carbonization furnace are provided with a gas inlet and a gas discharging port. The gas inlets of the activation furnace and the carbonization furnace are connected to a combustion furnace. According to the device, steam activation has no influence on carbonization. An activation process adopts the steam spraying tubes to spray the steam, and the activation spiral conveyer is cooperated for control, thus effectively controlling the using amount of the steam, ensuring full contact between the steam and a carbon layer, ensuring activation effects, and reducing the using amount of the steam. The heat of the activation itself can be utilized to heat the steam in the steam spraying tubes, thus reducing extra energy consumption for heating steam.

Description

technical field

[0001] The invention relates to a biomass material processing device, in particular to a biomass material carbonization and activation integrated device. Background technique

[0002] Biomass material charcoal activation can adopt the traditional steam activation method. The traditional method of carbonization and activation process is separated, manual transfer is required in the middle, and the labor intensity is high, and the carbonization activation process is carried out in batches, and the single batch processing volume is large. For the steam activation process, the amount of activation required for a single time is large. The difficulty of comprehensive contact between steam and charcoal is increased, and the treatment efficiency is low. Furthermore, in the activation process, it is necessary to heat to obtain high-temperature steam, and then pass it into the activation furnace, and the energy consumption of heating the steam is large.
