Abstract

The invention relates to a biomass gasification device and process. The device comprises a gasification reaction chamber, a steam heat exchanger, a steam buffer tank, an air buffer tank, an inner and outer double-cyclone heat exchanging dust collector, a cooling tower, an electro tar precipitator, a hydrogen sulfide removal sprayer, a water ring compressor, a gas-water separator, a gas storage tank and a control system of the device, which are connected through a gas pipeline; the gasification reaction chamber comprises an automatic feeding device, a two-stage gasification zone, a vibrating grate, an automatic ignition device, an automatic slagging device and an automatic leveling device. The gasification process comprises the following steps of: gas generation; gasification medium preheating; gas purifying and filtering; and gas compression and storage. The biomass gasification device and process are scientific and environment friendly, have the remarkable characteristics of simple structural design, high degree of automation as well as stable, controllable and continuous gasification reaction, have high gasification efficiency and entire caloricity, are suitable for popularization and application on a large scale, and are particularly applicable to continuous and stable generation of the traditional gas generating set.

Description

technical field [0001] The invention relates to dry distillation of carbonaceous materials to produce fuel gas, in particular to biomass gasification equipment and a gasification process. 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. At the same time, it is well known that the fossil fuels we use come from biomass, which is actually a 100% renewable and clean energy. [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 are generated on the earth due to photosynthesis base...

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] Existing biomass gasification equipment uses anaerobic combustion to generate combustible gas, but due to its simple structure and unreasonable design, there are many defects, such as: long smoke exhaust time, polluting the environment, unstable gas production, and high tar content in gas production. Blockage of gas pipelines, or damage and corrosion of terminal application equipment

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