Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum ash desulfurization technology, specifically to a secondary aluminum ash desulfurization device. Background Technology
[0002] Aluminum ash is a byproduct of aluminum smelting and processing, mainly composed of alumina, metallic aluminum particles, fluorides, chlorides and other impurities.
[0003] Secondary aluminum ash is mixed with water to form a slurry, which enters the flue gas desulfurization unit to react with sulfides in the flue gas, generating desulfurization products. The desulfurized slurry is then separated by a dehydration unit. The solid portion enters a reaction tank for maturation and polymerization, while the liquid portion can be recycled. The drying unit uses boiler flue gas to dry the desulfurizing agent, ultimately achieving resource utilization.
[0004] In existing mixing processes, localized high or low temperatures may affect the physicochemical properties of aluminum ash and desulfurizing agents. For example, excessively high temperatures may cause certain components to volatilize or undergo thermal decomposition reactions, producing sticky substances or making the material dry and prone to clumping; excessively low temperatures may cause moisture in the material to condense, promoting clumping.
