Biomass gasification system with high gasification rate

Abstract

The invention discloses a biomass gasification system with a high gasification rate, and relates to the field of biomass gasification. The biomass gasification system comprises a gasification furnace; a first purification box is arranged on one side of the gasification furnace and is connected with the gasification furnace through a connecting pipe; the side wall of the first purification box is fixedly connected with a second purification box which is arranged in an inclined manner; one side of the second purification box is fixedly connected with a combustible gas collecting pipe which is communicated with the second purification box; and a dispersing and stirring part which integrates functions of overturning and stirring biomass and dispersing catalytic liquid is arranged in the gasification furnace. The biomass gasification furnace is reasonable in structure. Biomass in the gasification furnace is stirred and overturned, so that the biomass is uniformly heated. A catalyst can be uniformly dispersed on the biomass, the gasification speed and gasification rate of the biomass are improved, produced combustible gas is purified, purification is sufficient and uniform, the purity of the combustible gas is improved, and later use of combustible gas is facilitated.

Description

technical field [0001] The invention relates to the field of biomass gasification, in particular to a biomass gasification system with high gasification rate. Background technique [0002] Biomass energy is the solar energy converted and stored by green plants through photosynthesis. It is an important renewable resource and the earliest energy actively used by humans. It has played an important role in the history of human civilization. So far, biomass energy is still the fourth primary energy consumption in the world, and it is widely used in rural areas of our country and developing countries. The traditional biomass energy utilization method is mainly direct combustion in household stoves, which is a continuation of the natural economic life style. Modern biomass energy technologies include thermochemical conversion and biochemical conversion.

AI Technical Summary

Problems solved by technology

[0003] When the existing biomass gasification equipment gasifies the raw material, it cannot fully contact the raw material and the catalyst in the gasifier, and the raw material is heated unevenly in the gasifier, which reduces the gasification rate of the raw material. The combustible gas produced by gasification is usually purified by spraying. In this way, the combustible gas cannot be fully contacted with the spray liquid, which reduces the purification effect of the combustible gas. Therefore, this application provides a high-efficiency Gasification rate of biomass gasification system to meet demand
