| titleOfInvention | An efficient and clean secondary aluminum ash harmless treatment method |
| abstract | The invention relates to the technical field of aluminum ash treatment, and discloses an efficient and clean secondary aluminum ash harmless treatment method. The secondary aluminum ash is added to a defluorination agent and a heavy metal remover, and then ground and homogenized, and then subjected to high temperature treatment. Roasting, the clinker obtained after roasting is a high-alumina inorganic material. The dust generated in the roasting process is captured by the dust removal device, and the filtered flue gas after the dust removal is absorbed and defluorinated by wet method, and then discharged up to the standard after ozone denitrification. After the collected dust is dissolved in water, evaporative crystallization treatment is performed to obtain a crystalline salt. The invention can cleanly, safely and efficiently process secondary aluminum ash, has the characteristics of simple process flow and low energy consumption, can realize high-value resource utilization of secondary aluminum ash, has strong market adaptability and wide application range. |
