Biomass granular fuel gasification carbon-making device

Abstract

The invention provides a biomass granular fuel gasification carbon-making device. The biomass granular fuel gasification carbon-making device comprises a feeding system, a combustion system, an air supply system, an ignition system, a spraying system, a carbon storage system, a cooling system and a control system. The combustion system comprises a combustion chamber communicating with the feedingsystem, a combustion auger, a limiting flow guide cover plate and a motor; the air supply system comprises air blowers communicating with the bottom and the middle of the combustion chamber through air pipes respectively and an air compressor communicating with two stages of air pipes, the two stages of air pipes are connected in parallel and then communicate with an air collecting hood fixed to the top of the combustion chamber, and a primary air loop and a secondary air loop are formed by the two stages of air pipes and the combustion chamber. The carbon storage system comprises an upper coke channel, a middle coke channel, a lower coke channel and a bottom carbon storage chamber which sequentially communicate with one another. The water flow direction of cooling water in the cooling system is opposite to the sliding direction of coke. A structure of feeding from bottom and carbon discharging from top is adopted, the strong reducibility of a high-temperature carbon layer is used forreducing the emission of nitrogen oxides, and diversified gas distribution and control measures can adapt to different types of biomass granular fuels.

Description

technical field [0001] The invention relates to a biomass particle fuel gasification carbon production device, which belongs to the technical field of biomass pyrolysis gasification carbon production. Background technique [0002] my country is rich in biomass resources, and the utilization of biomass resources has attracted more and more attention from the public. The volatile content of biomass pellet fuel is high. In the actual use of household biomass pellet stoves, there are generally problems such as insufficient combustion leading to high emissions of nitrogen oxides, particulate matter, carbon monoxide and other pollutants. Compared with biomass pellet fuel, the volatile content of coke produced after biomass pellet pyrolysis is significantly lower, the fixed carbon content is greatly increased, and the combustion characteristics are closer to coal. Therefore, the research on pyrolysis of biomass particles to produce coke is gradually entering the field of vision of...
