Biomass gasification equipment and process

Abstract

The invention relates to a biomass gasification device and a gasification process. The biomass gasification device comprises a fan, a gas generator, a gas purification device, a pressure vessel and a gas conveying pipe network of a user terminal. The biomass gasification device is characterized by also comprising a water ring compressor and a gas-water separator. The biomass gasification device converts a biomass material with low thermal value and waste into clean environment-friendly biomass fuel gas with high thermal value, has a reasonable and compact structure, small occupied area, and simple, high-efficient and safe process, and obtains clean pollution-free fuel gas with high purity and in particular solves the problem of the separation of wood tar, thereby effectively preventing erosion, blockage and environmental pollution in a pipeline; and the biomass gasification device has wide application and in particular realizes fueling and channelization of biomass waste in rural area as soon as possible so that common rural people, like urban people, can use clean and convenient fuel gas.

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 is an important material basis for the development of the world's human society and economy, and the main source of power for the development of productive forces. The development of the world economy fully demonstrates that the growth rate of energy is positively correlated with the synchronous growth of GNP. The great development of the world capitalist economy in the post-war 50s to 70s was closely related to the sufficient supply of cheap energy, especially the supply of oil. For this reason, energy supply has aroused widespread concern in the world. [0003] World energy issues have different impacts on countries around the world. Countries around the world take corresponding countermeasures and measures according to their respective national con...

Problems solved by technology

[0008] The aforementioned patent uses an explosion-proof air compressor as the driving force for generating gas to flow in the entire device, and as the driving force for compressing pure gas; under the action of the vacuum pump, the gas containing impurities undergoes a settling and filtering 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 a long time , the working efficiency of the air compressor will inevitably decrease; thus greatly reducing the gasification efficiency of the whole set of equipment
