Low-temperature cracking biomass gasification reaction cabin

Abstract

The invention belongs to the technical field of biomass gasification equipment, and particularly relates to a low-temperature cracking biomass gasification reaction cabin. The low-temperature cracking biomass gasification reaction cabin comprises a cabin body and an automatic feeding mechanism, wherein the inner wall of the cabin body is provided with a heat insulation layer; the upper end of the cabin body is provided with an upper cover; a charging opening, a cabin-inside material loosening, flattening and rolling structure, a circulation chimney, a water inlet, a water outlet, a gas outlet and a sensor are arranged on the upper cover; the charging opening is connected with the automatic feeding mechanism; a plurality of temperature sensors are arranged inside the cabin body; a 360-degree air sleeve is arranged on the periphery of the cabin wall of the cabin body; an air supply fan and a plurality of automatic air outlets are arranged on the 360-degree air sleeve; the lower part of the cabin body is provided with a slag breaking knife transmission system and a nanometer stacked oxygen supply mechanism; a slag outlet packing auger is arranged under the lower cabin body. The low-temperature cracking biomass gasification reaction cabin has the advantages that the low-temperature cracking and low-temperature gasification of biomasses are realized; the equipment structure is simple; the oxygen supply in the cabin is uniform, so that the biomass cracking is more full; the gas gasification rate is high; the tar content is reduced.

Description

technical field [0001] The invention belongs to the technical field of biomass gasification equipment, and in particular relates to a low-temperature pyrolysis biomass gasification reaction chamber. Background technique [0002] Energy and environmental protection are two major problems that need to be solved in the world today. Most of the energy supply still relies on fossil fuels, but the various pollutants emitted during combustion make the environmental problems worse. The fact is that the fossil fuels we use come from biomass, which is actually a 100% renewable and clean energy source. Biomass resources are very rich, such as municipal solid waste (MSW), forest trees, agricultural waste and other carbon-rich organic materials are excellent biomass resources. Every year, 140-180 billion tons of biomass are generated on the earth due to photosynthesis based on chlorophyll. The chemical energy stored in these biomasses is more than three times the world's total energy c...

Problems solved by technology

The chemical energy stored in these biomasses is more than three times the world's total energy consumption, but our current utilization rate is less than 3% of the total

The existing biomass gasification reaction chamber uses anaerobic combustion to generate combustible gas, but due to its simple structure, the design

[0003] Unreasonable, there are many defects, such as: unstable gas production, continuous operation of slag discharge feed, uncontrollable gasification reaction, high tar content in gas production, resulting in blockage of gas pipelines, so it cannot be used continuously for a long time, and it is not convenient for storage and transportation or Large-scale promotion and application
