Coal gasifier for coal gasification production

Abstract

The invention discloses a coal gasifier for coal gasification production. The furnace comprises a furnace body, an ash locking bin is arranged at the bottom of the furnace body; a water jacket is sleeved outside the furnace body. In the coal gasifier, the movable frame and the rolling wheels are arranged, therefore, the coal can intermittently fall into the coal separator, and excessive coal carried in the coal separator due to the fact that a large amount of coal enters the furnace body in a short time is avoided; the phenomenon that a large amount of coal cannot fully react after entering the furnace body is avoided; by means of the filter screen, coal gas mingled with residual coal ash enters the gas outlet pipe; the residual coal ash is blocked by the filter screen; coal ash is prevented from entering the air outlet pipe; meanwhile, the filter screen can block water drops mixed in coal gas, so that the gas outlet pipe is prevented from being corroded; and by arranging a brush, after the filter screen is blocked after being used for a long time, a cam is driven by a third motor to rotate, so that the cam drives a pull rod to move back and forth through a movable rod, and then the brush cleans the filter screen.

Description

technical field [0001] The invention relates to the field of coal gasification production equipment, in particular to a coal gasification furnace for coal gasification production. Background technique [0002] Coal gasification refers to the process in which coal, coke, semi-coke and other solid fuels react with gasification agents under high temperature, normal pressure or pressurized conditions, and are converted into gas products and a small amount of residue. The gasification agent is mainly water vapor, air (or oxygen) or their mixture, and the gasification reaction includes a series of homogeneous and heterogeneous chemical reactions. The obtained gas products have different compositions depending on the quality of raw coal used, the type of gasification agent and the gasification process, and can be divided into air gas, semi-water gas, water gas, etc. The coal gasification process can be used to produce fuel gas, which is used as industrial kiln gas and city gas, an...

Problems solved by technology

[0003] Since the reaction of coal in the coal gasifier takes a certain amount of time, it is necessary to control the amount of coal entering the coal gasifier, and the existing coal gasifier lacks a device to control the amount of coal, which leads to a large amount of coal in the coal separator. Accumulation, and then cause a large amount of coal to enter the coal gasifier in a short period of time, and cause the coal to fail to fully react in the coal gasifier, thereby causing a waste of resources. At the same time, the coal gas produced by the coal gasifier contains a large amount of coal ash, However, the current washing cooler lacks a filter device, which causes part of the coal ash to be discharged with the gas
