Method for conducting rail-mounted type automatic slag discharging on gasification furnace

Abstract

The invention belongs to gasification furnace automatic ash slag discharging, conveying and removal technologies, and relates to a method for conducting rail-mounted type automatic slag discharging on a gasification furnace. An automatic slag discharging car conducts automatic slag discharging on the gasification furnace, a fixed rail is arranged on the ground below the gasification furnace, and the automatic slag discharging car walks on the fixed rail; when the gasification furnace needs to discharge ash slag, the automatic slag discharging car automatically moves to the position, where slag discharging is needed, below the gasification furnace along the rail, and a slag receiving device on the automatic slag discharging car is automatically aligned to a gasification furnace ash discharging valve for closed slag discharging operation; after slag discharging of the gasification furnace is completed, the automatic slag discharging car moves to a fixed slag discharging point along the rail according to an instruction, and a slag discharging door is automatically opened to discharge ash slag to a slag receiving device below the slag discharging door; after one-time slag discharging operation is completed, the automatic slag discharging car completes next slag discharging operation according to a next slag discharging request signal.

Description

technical field [0001] The invention belongs to the technology of automatic slag unloading, transportation and slag discharge of gasification furnace ash and slag, and relates to a track-type automatic slag unloading method for gasification furnace. Background technique [0002] The gasifier is a device specially used in the coal chemical industry to produce useful gases such as coal gas. It produces the required industrial gases such as coal gas through the combustion of coal. The combustion of coal produces a large amount of ash, which needs to be discharged in time to ensure the continuous and normal production of the gasifier. The traditional gasifier slag unloading method uses the driver to drive the unloading truck or the belt conveyor to unload. [0003] After many years of practical experience and the summary of the current use of the manufacturer, manual driving of unloading trucks to unload slag, the operating environment is harsh, manual participation is frequent...

AI Technical Summary

Problems solved by technology

[0003] After many years of practical experience and the summary of the current use of the manufacturer, manual driving of unloading trucks to unload slag, the operating environment is harsh, manual participation is frequent, open slag unloading has a great impact on the environment, and the site cleanliness is poor; belt conveyor slag unloading has operational stability Not good, due to the uneven particle size of the slag block and the phenomenon of bonding, the failure rate of the belt conveyor is high, the dust is difficult to seal during slag discharge, and it has a great impact on the site environment, etc.

At present, the above-mentioned slag unloading methods have a low level of automation, frequent manual participation, poor site environment cleanliness, and low slag unloading efficiency of the gasifier
