AI Technical Summary

Technical Problem

Liquid polyaluminum chloride suffers from low drying efficiency, scattered atomized droplets, low thermal efficiency, and the particles tend to adhere to the inner wall or stick together after drying, affecting the smoothness of feeding and causing material waste.

Method used

The drying device combines a centrifugal atomizing disc with a hot air furnace. The atomized droplets are controlled by the air outlet, the fan blades extend the contact time between the droplets and the hot air, and the scraper and spiral blades prevent the particles from sticking to the wall. The storage box is designed for easy discharge.

Benefits of technology

It improves drying efficiency, avoids material waste, ensures smooth discharge, prevents particles from sticking to the wall and clogging, and enhances the overall drying effect.
