Description

Technical Field

[0001] The present application relates to the field of tail gas purification, and more specifically, to a tail gas purification device for sintered gangue shale bricks. Background Art

[0002] Gangue is a solid waste discharged during the coal mining and coal washing process. Gangue can be used to burn into bricks to achieve waste utilization, but gangue encounters high temperatures during the burning process to produce smoke particles and gases such as sulfur dioxide. In order to avoid polluting the environment, it is necessary to purify the exhaust gas discharged. The patent document with the prior art publication number CN208115475U provides a sintered brick exhaust gas purification system containing gangue. The device uses a multi-layer honeycomb plate for gas-liquid mixing, and the gas and liquid flow upward during the mixing process. Therefore, the contact area between the gas and the liquid is large, the mixing degree is uniform, and the efficiency of both dust removal and neutralization is greatly improved. The treatment process is that the first treatment tank adsorbs the smoke, and then passes through the gas thermal catalyst, in which nitrogen monoxide and nitrogen dioxide react with carbon monoxide to generate nitrogen and carbon dioxide, and finally reacts with the injected neutralization water in the second treatment tank and is discharged.

[0003] In view of the above-mentioned related technologies, the inventor believes that after the tail gas contacts water in the mixing chamber, smoke and dust are separated, and the smoke and dust with large mass fall under the action of gravity, so that they will accumulate on the honeycomb plate, causing the honeycomb plate to be blocked, making it difficult for the tail gas and water to flow, and the practicality is poor. Therefore, we propose a coal gangue shale sintered brick tail gas purification device. Utility Model Content

The motor 12 drives the T-tube 3 to rotate, and the T-tube 3 drives the spoiler 5 and the auger blade 8 to rotate. The spoiler 5 rotates the water in the water tank 2, so that after the exhaust gas contacts the water, the smoke particles move to the inner wall of the water tank 2 under the action of the rotating water flow.
