Automatic deslagging and stirring device

Abstract

The invention relates to the technical field of cleaning of coal gas generators, specifically to an automatic deslagging and stirring device. The automatic deslagging and stirring device comprises a driving mechanism, a driving shaft and a scraping plate capable of rotating with the driving shaft as an axis, wherein the driving shaft is connected with the driving mechanism; the scraping plate is fixedly arranged on the driving shaft and located in the interior of a coal gas generator; and the rotation radius of the scraping plate is equal to the radius of the coal gas generator. According to the invention, through rotation of the scraping plate with the driving shaft as a center under the driving by the driving mechanism, slag attached to the walls of the coal gas generator is scraped below a liquid level, and a stirring effect is exerted during rotation of the scraping plate to prevent scaling caused by sinking and accumulation of ash slag, so the ash slag is effectively prevented from forming blockage, and long-term stable operation of the coal gas generator is guaranteed; meanwhile, the stirring speed and slag-scraping intensity of the scraping plate can be controlled through control of the rotating speed of the driving mechanism, so automatic deslagging and automatic stirring can be realized, and problems of high labor intensity and low work efficiency of artificial deslagging are solved.

Description

technical field [0001] The invention relates to the technical field of gas generator cleaning, and more specifically, to an automatic slag removal and stirring device. Background technique [0002] In order to provide hydrogen source and coal gas, promote direct coal liquefaction and simple liquefaction industry, and develop the overall coal gasification combined cycle function, the pre-purification of coal gas removes NH 3 , HCN, HCl, HCOOH and ash are particularly important. Gas generators, cyclone dust collectors, waste heat boilers and intercoolers are often used to purify gas. However, the dust and some tar mixtures generated during the gas purification process accumulate on the liquid surface and cannot be dissolved in water. Long-term accumulation will lead to serious blockage, which is not conducive to the long-term stable operation of the gas generator, and there is a great safety hazard Hidden danger.
