Experimental coke oven gas purification device

Abstract

The invention discloses an experimental coke oven gas purification device which comprises a centrifugal separator and a supporting frame body arranged on one side of the centrifugal separator, a coal tar pipeline is arranged on the supporting frame body, the coal tar pipeline communicates with a feeding port of the centrifugal separator, a tar residue smashing mechanism is further arranged on the coal tar pipeline, a side wall cleaning mechanism is further arranged at a tar residue discharging port of the centrifugal separator, and a hot gas pipeline is arranged on the side wall cleaning mechanism. The experimental coke oven gas purification device is different from the prior art, during purification treatment of raw gas, tar residues entering the coal tar pipeline can be subjected to secondary crushing through the tar residue crushing mechanism, so that a feeding hole of the centrifugal separator is prevented from being blocked, and when the side wall cleaning mechanism is used for cleaning the tar residue discharge hole of the centrifugal separator, tar adhered to the side wall is synchronously cleaned.

Description

technical field [0001] The invention relates to the technical field of coke oven gas purification devices, in particular to an experimental coke oven gas purification device. Background technique [0002] Although coking coal accounts for 72% of the more than 1 trillion tons of "ascertained resource reserves" in my country, gas coal (including 1 / 3 coking coal) has the most "ascertained resource reserves" among coking coals, accounting for 10% of the total resources. 12%; coking coal accounted for 6%; lean coal, lean coal and fat coal, gas fat coal accounted for 4% and 3% respectively. According to the situation of my country's coal resources, expand the scope of coking coal, use non-coking coal for coking, and add additives, such as binders and thinners, to coking coal blending to rationally use coking coal resources and improve the efficiency of coking coal blending Technical measures are of great significance to promote the development of my country's coking industry; [0...

Problems solved by technology

[0005] 1. The size of the tar block produced after ammonia water treatment is relatively large, and it is very easy to block the feed inlet of the horizontal centrifuge. Most of the existing ones are equipped with a press at the feed inlet, but after being squeezed by the press, it is still possible There are large lumps of tar, and the squeezed tar blocks are difficult to fall directly, and the filter plate is often blocked, so it is necessary to dredge the pipeline, but the environment inside the pipeline is poor, and it is difficult to clean;

[0006] 2. According to the data, tar is 1.12kg / L~1.20kg / L, tar residue is 1.25kg / L~1.26Kg / L, and the viscosity of tar is greater than that of liquid water. After centrifugation with a conventional horizontal centrifuge , there will be some tar attached to the tar residue and discharged from the discharge port. Under the action of the drum and the screw unloader, the discharge state is in the state of outward rotation and spraying. Therefore, a large amount of tar will adhere to the inner wall of the discharge port pipeline. tar residue, for this reason, we propose an experimental coke oven gas purification device
