Technical Field

[0001] The utility model belongs to the technical field of aluminum chloride processing, and particularly relates to a tail gas collection device for aluminum chloride processing. Background Art

[0002] In the process of producing aluminum chloride, a large amount of tail gas will be generated. In order to avoid tail gas pollution, the tail gas will be first purified by a tail gas collection device. The existing tail gas collection device for aluminum chloride processing can meet the basic needs of acid-base neutralization treatment of tail gas, but the tail gas often leaves the alkaline neutralization liquid directly along the vertical path after entering the neutralization container. The tail gas stays in the alkaline neutralization liquid for a short time and the path liquid is also short, which often cannot fully meet the neutralization requirements of the tail gas, so it will bring great inconvenience to people's use.

[0003] For example, the utility model with the announcement number CN 217909741 U discloses an anhydrous aluminum chloride tail gas absorption device. In the technical solution of this patent, after the tail gas enters the neutralization box, it will run to the top of the alkaline neutralization liquid along a vertical path. The tail gas stays in the alkaline neutralization liquid for a short time and the path liquid is also short, so it will lead to poor neutralization effect on the tail gas and cannot fully meet people's needs.
