Technical Field

[0001] This utility model relates to the field of chemical production equipment technology, specifically to a drying device for polyaluminum chloride. Background Technology

[0002] Polyaluminum chloride is usually dried using spray drying and vacuum rake drying. In spray drying, the polyaluminum chloride solution is sprayed into tiny droplets through a sprayer and then comes into contact with hot air, causing the moisture to evaporate rapidly, thereby obtaining dried polyaluminum chloride powder.

[0003] The prior art disclosed in the patent document, with publication number CN221099216U, is as follows: A drying tower for polyaluminum chloride, relating to the field of polyaluminum chloride drying technology. The present invention includes a tower body, with a baffle fixed on the other side inside the tower body, and a rotating shaft penetrating through the top of the tower body, with a connecting cylinder connected to one end of the rotating shaft.

[0004] The water collection block in the above technical solution is designed with an incline. As the condensate flows along the incline to the edge, it may drip due to insufficient surface tension or airflow disturbance, causing humidity fluctuations in the tank and prolonging the drying time.
