Biomass gasification furnace

Abstract

The biomass gasifier comprises a gasifier body, an air inlet device, an igniter and a purification device, the air inlet device is arranged in the center of the bottom of the gasifier body, the igniter is arranged on the upper middle portion of the gasifier body, and the purification device communicated with an inner cavity of the gasifier body is arranged at the top of the gasifier body. By arranging the purifier, only a small amount of tar mist exists in the purified combustible gas, meanwhile, the combustible gas can enter the pyrolysis cavity again to be pyrolyzed, the pipeline cannot be blocked, the burner cannot be blocked, environmental protection is achieved, and the problem of treatment of tar and sewage generated in the biomass gasification process is solved to the maximum extent; and meanwhile, the production cost is reduced. The produced combustible gas is subjected to multi-channel pyrolysis gasification through the pyrolysis cavity, and the purity of the discharged combustible gas is very high and can reach 98% or above.

Description

technical field [0001] The invention relates to the technical field of industrial gasifier devices, in particular to a biomass gasifier. Background technique [0002] The straw gas produced by the biomass gasifier belongs to green new energy and has strong vitality. The raw materials produced by the plant gas are crop straw, forest waste, edible fungus residue, cattle, sheep and livestock manure and all combustible substances. It is an inexhaustible renewable resource. When the current biomass gasifier is in use, it contains too much tar. It needs to be cooled and purified to separate the tar from the waste water. After water film treatment, it is purified by electric tar catcher, which has high energy consumption and high cost, so a biomass gasifier is needed. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a biomass gasifier to achieve the purpose of solving the problems raised in the above background technology. [0004] In order t...

Since the raw materials produced by the plant gas are crop straw, forest waste, edible fungus residue, cattle and sheep manure and all combustible substances, it is a It is an inexhaustible renewable resource. When the current biomass gasifier is in use, it contains too much tar. It needs to be cooled and purified to separate the tar from the waste water. After the water film treatment, it is purified by an electric tar collector, which has high energy consumption and high cost, so a biomass gasifier is needed
