Description

A tar ammonia scraping device

Technical Field

The utility model relates to the technical field of coking and gasification equipment, in particular to a tar ammonia water scraping device.

Background Art

The raw gas from the dry distillation furnace, along with tar and ammonia water, goes to the water washing tower along the gas pipeline. After the water washing tower, the raw gas is led out from the top and enters the subsequent production process. The tar-ammonia water mixture separated by the water washing tower enters the tar-ammonia water tank. The good or bad operation of the equipment is crucial to the separation of tar, ammonia water, and tar residue. With the production, more and more coal powder, coke powder, and tar residue are brought into the tar-ammonia water tank, which is easy to cause pipeline blockage, resulting in the inability to transport ammonia water in the tank in time.

In order to overcome the above-mentioned shortcomings, the tar ammonia water tank in the prior art usually adopts submersible pump extraction and manual cleaning. During the operation of the equipment, due to the influence of tar residue, it is very easy to cause blockage of the centrifugal pump impeller and the inlet pipe, and the ammonia water tank needs to be manually cleaned regularly. In this process, it will cause production interruption or high risk during the operation of cleaning the ammonia water tank, affecting the normal production order.
