Biomass gasification device and gasification technology

Abstract

The invention relates to a biomass gasification device and a gasification technology. The device comprises a blower, a gas generator, a gas purifying device, a pressure vessel and a user end gas transmission pipeline network, and is characterized in that the device further comprises a water ring compressor and a moisture separator, and the gas purifying device comprises a cyclone separator and a composite filter device. The invention transforms low heat value biomass materials and wastes to high heat value clean and environment-friendly biomass gas, has the advantages of simple technology, scientific design, and energy conservation and emission reduction; and the invention has a wide application range, particularly causes biomass wastes in rural areas to achieve gasification and channelization as soon as possible, and enables civilians in the rural areas to use clean and convenient gas as the same as urbanites.

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] At present, coal, oil, natural gas and other non-renewable resources are generally used as the main fuels in the world. Most of the fuels produce a large amount of harmful gases and smoke during the combustion process. However, biomass gasification equipment does not need to burn the fuel directly, but will A kind of equipment that produces flammable gas under the condition of oxygen deficiency; because biomass and organic waste are an inexhaustible resource, it can be used as waste and can be cleaned environment and reduce environmental pollution. [0003] At the same time, it is well known that the combustible gas produced under the state of anoxic combustion contains a large amount of dust, wood tar and wood vinegar, and the most difficult problem to hinder...

AI Technical Summary

Problems solved by technology

[0006] (1) The above-mentioned patent uses an explosion-proof air compressor as the power to generate gas flowing in the entire device, and as the power to compress pure gas; under the action of the vacuum pump, the gas containing impurities is settled and filtered one by one After operation, it still inevitably contains a small amount of wood tar. Due to its large specificity and high viscosity, when the gas passes through the air compressor, it will naturally stick to the inner wall and pressure ring of the air compressor. It must be cleaned in time, otherwise it will take time Over time, the working efficiency of the air compressor will inevitably decrease; thus greatly reducing the gasification efficiency of the entire device

[0007] (2) The structure of the whole device is complicated, it occupies a large area, there are many gasification processes, and the workload of installation and maintenance is heavy, which increases the process cost and reduces the gasification efficiency
