AI Technical Summary

Technical Problem

In existing cryogenic sublimation crystallization devices, the large volume of ice blocks results in a small contact area, slow sublimation rate, and uneven ice fragmentation, leading to long processing cycles, low efficiency, and low crystal purity.

Method used

The ice crushing component is used to squeeze and vibrate the ice blocks, and the automated linkage design of the spreading component ensures that the crushed ice is evenly scattered and fully contacts the inner wall of the sublimation crystallization box. The spiral scraper is used to achieve efficient transportation of the crystallized solids.

Benefits of technology

It improves the sublimation rate and crystallization purity of wastewater treatment, realizes efficient and continuous automation of wastewater treatment, and reduces equipment energy consumption and failure rate.
