Description

Technical Field

[0001] The utility model relates to the field of dust treatment, in particular to a dissolution grinding steam powder separator. Background Art

[0002] During the sintering alumina production process, wet dust pollution at the dissolution mill inlet is a major problem. Dust from the clinker and steam from the mill inlet mix together, forming a scabbing mass. Workers are required to clean the inlet scabbing with hammers and picks every two hours. Furthermore, the dust is highly alkaline, posing a significant risk to worker health, ambient air, and surrounding equipment. Bag filters with sticky bags are unusable, and wet dust removal equipment is large and complex, with high costs and maintenance. Therefore, many manufacturers use large-diameter pipes to directly exhaust the dust outside the factory, which is unacceptable under the current environmental protection situation. Therefore, we proposed a dissolution mill steam-dust separator, which allows dust to be collected by bag filters, achieving the goal of dust control. Summary of the Invention
