Abstract

The invention discloses an integrated process and device for semicoke coal gas. The integrated device sequentially comprises a coal gas pretreatment system, a desulfuration circulating system and a sulfur recovery system, wherein the coal gas pretreatment system comprises a cooler, a drop catcher and an electrostatic detarrer which are sequentially connected, an inlet of the coal gas pretreatment system is connected with a coal gas input conduit, an outlet of the coal gas pretreatment system is connected with the desulfuration circulating system, a coal gas outlet of the desulfuration circulating system is connected with a coal gas output conduit, and a circulating liquid outlet of the bottom of the desulfuration circulating system is connected with the sulfur recovery system. By adopting the process and the device, the temperature of the semicoke coal gas can be dropped, coal tar and sulfides are removed from the semicoke coal gas, valuable substances are recovered, and the quality of the semicoke coal gas is improved; the process and the device have the advantages that the investment is small, the stability is good, the routine maintenance is simple, the operating cost is low, and the like.

Description

【Technical field】 [0001] The invention relates to a gas purification treatment device, in particular to an integrated process and device for semi-coal gas cooling, oil removal, dust removal and desulfurization. 【Background technique】 [0002] As an integral part of clean coal technology, semi-coke production technology can realize efficient and clean utilization of coal resources and save energy; especially the use of Jurassic coal not only solves the long-standing problem of unbalanced coal resources, but also contributes to the development of the Yulin Shenfu area. Rich coal deep processing has found a new way, which is considered by everyone to be an ideal product for the upgrading of the coal industry. It is a project with significant economic benefits and good social benefits. [0003] Semi-coke production belongs to low-temperature dry distillation, which is to heat coal at about 600°C under the condition of isolating air and oxygen to decompose it into tar, semi-coke ...
