Ascending coal gas dust blocker

Abstract

The invention aims to provide an ascending coal gas dust blocker for solving the problems of purifying gas, prolonging the service lives of pipelines and equipment and balancing gas distribution. Dust blocking plates are arranged on a circular shell, air outlets are formed between the dust blocking plates, and the dust blocking plates are 'V'-shaped and bent inwards. The dust blocker is simple in structure and convenient for manufacturing and installing; through the dust blocker, the dust carried in the coal gas can be effectively blocked to a furnace body and discharged together with slag at the up-blowing stage; when the steam passes through the dust blocker at the down-blowing stage, the steam can be uniformly distributed, so that the original steam flowing mode is changed; and by reducing the dust in the ascending coal gas, the coal gas is purified, meanwhile, scouring to an ascending coal gas pipeline and a lining of a dust collector is relieved, safe and stable operation of equipment is ensured, and the operating cost is saved.

Description

technical field [0001] The invention relates to the field of gas purification, in particular to an upward gas ash retainer. Background technique [0002] At present, in the synthetic ammonia nitrogen fertilizer enterprise that adopts the fixed-layer batch method to make gas, the operation quality of the gas-making furnace directly affects the operation of the latter section, which has an important impact on the economic benefits of the company. The situation is difficult to control, causing serious air leakage in the upward gas pipeline, and the thinning of the dust collector lining will affect the service life. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an upward gas ash retainer, which solves the problem of gas purification, prolongs the service life of pipelines and equipment, and evenly distributes gas. [0004] The present invention is realized in the following way: the ash retaining plate is installed on the circular shell, ...

Problems solved by technology

[0002] At present, for synthetic ammonia-nitrogen fertilizer enterprises that adopt the fixed-layer intermittent method to produce gas, the quality of the gas-making furnace directly affects the operation of the subsequent section, which has an important impact on the company's economic benefits. Often due to the unstable operation of the gas-making furnace, the furnace The situation is difficult to control, resulting in serious flushing and gas leakage of the upstream gas pipeline, and the thinning of the lining of the dust collector affects the service life
