Biomass gasification hot charcoal co-production system with independent oxidation chamber

Abstract

The invention provides a biomass gasification hot charcoal co-production system provided with an independent oxidation chamber, and relates to the technical field of biomass comprehensive utilization equipment, the biomass gasification hot charcoal co-production system comprises an oxidation furnace and a gasification furnace which are independently arranged, the oxidation furnace and the gasification furnace are connected through a flue gas pipe, the flue gas pipe is provided with a flue gas pipe valve, and the flue gas pipe valve is connected with the gasification furnace. The flue gas pipe is further connected with one end of a flue gas circulating pipe, the other end of the flue gas circulating pipe is communicated with an oxidation chamber of the oxidation furnace, and the flue gas circulating pipe is provided with a flue gas circulating valve and a flue gas circulating fan; and an oxygen detection device, a temperature sensor and a flow meter are respectively arranged on the flue gas pipe on a pipeline between the flue gas pipe valve and the oxidizing furnace. The oxidation furnace is independently arranged, the oxidation process (combustion) is independently carried out and controlled, the reaction intensity can be easily controlled, the biomass gasification production process can be conveniently and rapidly adjusted and controlled in a wide range by controlling the reaction intensity of the oxidation furnace, and high-quality gas-carbon co-production is achieved.

Description

technical field [0001] The invention belongs to the technical field of biomass comprehensive utilization equipment, and in particular relates to a biomass gasification thermal carbon co-production system equipped with an independent oxidation furnace to simultaneously produce combustible gas and biomass carbon after biomass cracking and gasification. Background technique [0002] Biomass gasification can be divided into carbon-producing and non-carbon-producing from the product residue. The former has low utilization rate of biomass and the latter has high utilization rate of biomass. From the movement form of biomass material in the gasification process, it can be divided into For moving bed and fixed bed, the former has high gasification efficiency, but the quality of carbon production is the lowest, and the latter has low gasification efficiency, but the quality of carbon production is higher than that of the former. [0003] When building a biomass gasification system th...
