Downdraft biomass gasification reaction chamber and gasification process thereof

Abstract

The invention relates to a downdraft biomass gasification reaction chamber and a gasification process thereof. The downdraft biomass gasification reaction chamber comprises an automatic feeding device, a gasification region consisting of a primary gasification region and a secondary gasification region which are integrated, an automatic leveling device, a vibration grate, an automatic ignition device, an automatic deslagging device, an in-furnace pressure regulating system, a furnace temperature monitoring system, an in-furnace material level monitoring system, an inlet and output gas temperature monitoring system, an inlet and outlet pressure monitoring system and a flame monitoring system. The production process comprises the following steps of: automatically feeding and introducing gas, primarily gasifying, secondarily gasifying, and automatically deslagging. The downdraft biomass gasification reaction chamber is scientific and environmentally-friendly, has the remarkable characteristics of reasonable structure design, high automation, stable and controllable gasification reaction, continuity and no interruption, has high gasification efficiency and high integral heat value, issuitable for large-area popularization, and especially can be applied to continuous and stable power generation of the existing gas generator.

Description

technical field [0001] The invention relates to a biomass gasification device and a process, new energy-related technologies such as gas-fired power generation, and in particular to a biomass gasification reaction chamber and a gasification process thereof. 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. [0003] In a broad sense, biomass includes all plants, microorganisms, animals, and the wastes they produce. 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...

AI Technical Summary

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

[0004] The existing biomass gasification reaction chamber uses anaerobic combustion to generate combustible gas, but due to its simple structure and unreasonable design, there are many defects, such as: unstable gas production, continuous operation of slag discharge and uncontrollable gasification reaction , the ignition system is primitive and crude, and cannot be reused, and the high tar content in the gas will cause gas pipeline blockage, or damage and corrode terminal application equipment

Therefore, it cannot be used continuously for a long time, and it is not convenient for storage and transportation or large-scale promotion and application, so it cannot be applied to the continuous and stable power generation of existing gas-fired generator sets
