Description

Technical Field

[0001] The utility model relates to the technical field related to ammonium bifluoride, in particular to an ammonium bifluoride production tail gas treatment device. Background Art

[0002] Ammonium bifluoride is a corrosive chemical substance. Its aqueous solution is weakly acidic and can dissolve glass. It is slightly soluble in alcohol, very soluble in cold water, and very easy to deliquesce. It is mainly used as a glass etchant, disinfectant, preservative, solvent for metal beryllium, surface treatment agent for silicon steel plates, and also used in the manufacture of ceramics and magnesium alloys. Ammonium bifluoride will produce waste gas during the production process. Ammonium bifluoride is a toxic substance, so an ammonium bifluoride production tail gas treatment device is needed.

[0003] The existing technology has the following shortcomings: the existing ammonium bifluoride will produce tail gas during production. The tail gas has a certain toxicity and needs to be treated before it can be discharged. Some tail gas treatment devices use a spray tower to spray the waste gas, but the residence time of the tail gas in the spray tower is affected by the height of the spray tower. If the height of the spray tower is too high, a large amount of water resources will be required. If the spray tower is too low, the residence time of the tail gas will be affected, which will cause the tail gas to be not in sufficient contact with the water resources, thereby affecting the treatment effect of the tail gas.
