Two-way gas distribution device for large gas generator

Abstract

A two-way gas distribution device for large gas generator belongs to the field of gas generator device. The gas distribution device is especially applicable to a large-diameter hearth with the diameter Phi of 3.4m, 3.6m and 3.8m. The gas distribution device comprises a central gasification agent branch pipe (5) and a gas stove body (9) and is characterized in that a periphery gasification ring pipe (8) is arranged between the central gasification branch pipe (5) and the gas stove body (9), the periphery gasification ring pipe (8) surrounds outside the gas stove body (9) and is connected with the central gasification agent branch pipe (5) by a periphery gasification branch pipe (7) and a periphery branch gasification agent regulating valve (6), and the periphery gasification ring pipe (8) is provided with a plurality of gasification agent distribution regulating devices communicated with the gas stove body (9). The invention has the advantages that the gas distribution device can cause the gasification agent to be evenly distributed in the whole hearth space; the gasification agent distribution amount in the hearth can be easily adjusted; and the stove can be simply and fast adjusted when the stove is in deviation.

Description

technical field [0001] The utility model relates to a double-channel gas distribution device for a large-scale gas generator, which belongs to the field of gas generator equipment. It is especially suitable for furnaces with diameters of φ3.4m, φ3.6m and φ3.8m. Background technique [0002] Generally, the gasification agent (mixed gas of air and steam) of medium and small gasifiers (hearth diameter φ3.2 meters and below) is only sent to the furnace from the bottom of the gas furnace through the grate, and reacts with the lump coal in the furnace to generate gas . Due to the high resistance of slag and coal, it is difficult for the gasification agent to reach a long distance in the furnace, which limits the diameter of the gas furnace. , leading to incomplete combustion of coal, lower coal utilization rate, significant increase in carbon content of slag, lower gas production, and difficult to adjust when partial furnace occurs, unable to achieve the expected design effect. ...
