Description

Technical Field

[0001] The utility model belongs to the technical field of tail gas collection and treatment, in particular to an ammonia tail gas collection and treatment device. Background Art

[0002] Ammonia is a nitrogen-hydrogen compound that can be artificially synthesized and can be decomposed under certain conditions, is easy to transport and has high energy density. Synthetic ammonia refers to ammonia directly synthesized from nitrogen and hydrogen under high temperature, high pressure and the presence of a catalyst. It is a basic inorganic chemical process. In the modern chemical industry, ammonia is the main raw material for the fertilizer industry and basic organic chemical industry. The production process of synthetic ammonia will produce tail gases such as nitrogen, hydrogen and ammonia. The tail gases need to be treated to avoid direct discharge of ammonia into the air.

[0003] After the production of the car is completed, it needs to be tested in the workshop. Since the workshop is a closed space, the exhaust gas generated is difficult to be discharged in time, which poses a great safety hazard to the health of the operators. In addition, direct discharge will also cause the workshop to fail to meet environmental protection standards. Therefore, it is necessary to collect it. The existing workshop exhaust gas collection device mainly uses a gas collecting hood for collection, and enters the treatment system for purification after a series of transmission devices. The existing exhaust gas collection device uses a single and fixed gas collecting hood structure, and the workshop space size is different. This leads to a great limitation on the scope of application of the gas collecting hood, and correspondingly reduces its exhaust gas collection effect, so it needs to be improved.
