Abstract

The invention discloses a gasification agent injection device of a biomass gasifier, which comprises a gasification agent inlet pipe, a gasification agent outlet pipe erected in a gasifier body, an electric or manual speed reducer positioned at the top of the gasifier and an air inlet three-way joint fixed in the gasifier body, wherein the upper part of the gasification agent outlet pipe runs through upper and lower ports of the three-way joint to be connected with a main shaft of the speed reducer and to rotate along with the main shaft of the speed reducer under the positioning of the gas inlet three-way joint; the part of the gasification agent outlet pipe in the three-way joint is provided with a plurality of air inlets; the lower end of the gasification agent outlet pipe is communicated with at least one gasification agent injection pipe with a plurality of air injection holes; a transverse port of the air inlet three-way joint is connected with the gasification agent inlet pipe;joints between the gasification inlet pipe and the port of the air inlet three-way joint and between the gasification agent outlet pipe and the port of the air inlet three-way joint are in the state of high-temperature oil seal; and the outer pipe wall of the gasification gas outlet pipe is also provided with a material stirring device.

Description

technical field [0001] The invention relates to a biomass gasification furnace, in particular to a gasification agent injection device. Background technique [0002] Biomass gasification is based on biomass (such as dried straw, firewood, various organic substances, etc.) Known as gasification medium), the process of converting biomass into combustible gas through thermochemical reaction under high temperature conditions, the biomass gasification process is carried out in the biomass gasifier. A commonly used biomass gasification furnace includes a furnace body and a combustible gas purification device arranged outside the furnace body. The furnace body includes a feed inlet, a gasification agent inlet pipe (port), a combustible gas outlet, and an ash outlet. The mouth is added into the furnace body, and the gasification agent is input from the gasification agent inlet pipe (port) of the furnace body. When the gasifier is working, the dried biomass material is fed into the...
