AI Technical Summary
In existing polyaluminum chloride (PAC) recovery devices, byproducts or incompletely dissolved substances adhere to the device walls and agitators, reducing efficiency. The PAC solids do not have sufficient contact with the acid solution, resulting in slow dissolution and long reaction times.
The design incorporates scraping and mixing components, including scraper bars, rubber scrapers, and blades that interact with the mixing frame. The scraper bars, along with the blades, increase mixing efficiency, making the equipment more efficient during mixing.
It effectively removes sediment from the inner wall of the reaction vessel, improves stirring efficiency, ensures full contact between PAC solids and acid solution, and shortens reaction time.
