Abstract

The invention relates to a gasified gas purification device, in particular to a double-flow biomass gasified gas purification device, which solves the problems of low reaction temperature of a gasification furnace, abundant generated tar and wastewater, low gas-producing efficiency and abundant impurities and low heat value of output gas, resulted from unscientific structure of the gasification furnace. The gasified gas purification device comprises a gasification furnace, a gas flow control valve, a vortex flow oxidation-assisted control valve, a gas purifier and a fan. The gasified gas purification device provided by the invention has the advantages of increasing the reaction temperature of the furnace, wherein the temperature in oxidation, reduction and pyrolysis cylinders is between 1,300 and 1,600 DEG; increasing the gasification intensity; being capable of quickly separating moisture in biomass combustible gas so that gas quality is better; ensuring greatly reduced tar content in the combustible gas, less wastewater generated, high gas-producing efficiency and low environmental pollution due to the adoption of a mesh-type catalytic cracking device; and removing tar, moisture and ash in the gas through the gas purifier so that the heat value of the gas is improved. The gasified gas purification device is widely applied in industrial and civil fields.

Description

technical field [0001] The invention relates to a gasification furnace and a gas purification device. Specifically relates to a dual-flow biomass gasification fuel gas purification device. Background technique [0002] At present, the gasifiers used to convert biomass into biomass gas are mainly divided into two types, one type is fixed bed type, and the other type is fluidized bed type. The fixed bed gas furnace is divided into four types: upflow type, cross flow type, downflow type and open type according to the direction in which the biomass combustible gas flows in the gas furnace. The biomass raw material is divided into a drying layer, a thermal decomposition layer (distillation layer), a reduction layer and an oxidation layer from top to bottom in the fixed-bed gas furnace. There are intersecting phenomena between various levels. The current various types of biomass gasification furnaces are characterized according to the direction in which the biomass combustible ...
