Problems solved by technology
[0005] The composition of high-temperature dusty crude gas is very complex. The initial temperature of crude gas is about 500°C~800°C, and it is sensitive to temperature changes. Tar is easy to condense when the temperature decreases; Particles agglomerate and adhere to the inner wall surface of the equipment, causing blockage of equipment and pipelines, seriously affecting the service life of the dust removal device

Abstract
The invention discloses high-temperature efficient explosion-proof integrated modular dust removal equipment for pyrolyzed raw gas. The equipment comprises a machine shell, a high-temperature ceramicfiltering system, a high-pressure blowback system, a pre-dedusting system; a cavity allowing a medium to flow from a gas inlet to a gas outlet of the machine shell is formed in the machine shell; thehigh-temperature ceramic filtering system divides a cavity of the machine shell into a dust collecting chamber and an air purifying chamber which are independent, and the high-temperature ceramic filtering system is located in the dust collecting chamber and achieves communicating between the dust collecting chamber and the air purifying chamber; the high-pressure blowback system is mounted in theair purifying chamber and performs blowback work towards the dust collecting chamber; and the pre-dedusting system is positioned outside the shell and communicates with the dust collecting chamber. The dust removal equipment can directly filter high-temperature dust-containing raw gas, the situation that the raw gas needs to be cooled before being filtered by a cloth bag dust removal device in anexisting coal gas making process is improved, and the problem that dust of 2 [mu]m or less is removed and separated again is effectively solved.
Description
Technical field [0001] The present application relates to the field of coal-resistant gas removal and purification technology, and in particular, a thermally hydrolyzed coarse gas high temperature and efficient explosion-proof type is a modular dust removal device. Background technique [0002] Coal resistance refers to the process of venting air, water vapor or hydrogen in coal or coalke under high temperature and high pressure conditions, and is an important approach and means of cleaning and utilizing coal resources. [0003] The application of the coal gasification combined cycle power generation system has promoted the development of coal system, but the high-temperature gas produced by coal gas gas contains a large amount of dust, not only reduces gas quality, but also causes wear to gas turbine blades, and reduce gas turbines. Life and productivity. Therefore, it is necessary to perform dust purification treatment for high temperature gas produced by the coal system. [00...
