Abstract

The present invention discloses a fluidized-bed gasification furnace for treating biomass. According to the fluidized-bed gasification furnace, the fluidized-bed gasification furnace body comprises an upper cylinder having a cylindrical structure, a lower cylinder having a cylindrical structure, and a connection section for connecting the upper cylinder and the lower cylinder; and the fluidized-bed gasification furnace is characterized in that the diameter ratio of the upper cylinder to the lower cylinder is 1.5-2:1, the connection section has a top-removing cone structure, the inclination angle of the connection section is 45-75 DEG, the bottom portion of the lower cylinder is provided with a wind distribution plate, the wind distribution plate has a hollow round table structure having the large upper portion and the small lower portion, and the included angle between the wind distribution plate and the bottom portion of the lower cylinder is 20-55 DEG. According to the present invention, the biomass raw material can be subjected to the large-scale treatment with the fluidized-bed gasification furnace, the fluidized-bed gasification furnace has the high energy conversion rate, the tar content in the produced fuel gas is low, and the secondary pollution cannot be generated.

Description

technical field [0001] The invention relates to the field of biomass gasification furnaces. More specifically, the present invention relates to a fluidized bed gasifier for processing biomass. Background technique [0002] As a renewable energy source, biomass has the characteristics of renewability, low pollution and wide distribution. The use of biomass as an alternative energy source is also a clean development mechanism project generally implemented by developed countries in the world. In our country, more than 200 million tons of remaining crop straws are directly burned in the fields every year, which not only wastes straw resources, but also causes serious air pollution. Making full use of discarded straw resources can significantly improve the local atmospheric environment and reduce coal-burning production. massive greenhouse gas emissions. Biomass gasification adopts a variety of technical routes, but the overall characteristics are small scale, low energy conve...
