| titleOfInvention | Device and method for continuously producing aluminum sulfate octadecahydrate |
| abstract | The invention discloses a device and a method for continuously producing aluminum sulfate octadecahydrate, belonging to the technical field of comprehensive utilization of waste sulfuric acid. The device comprises a waste sulfuric acid tank, a sulfuric acid delivery pump, an elevated tank, a first raw material mixing kettle, a solid feeding bag, a raw material pump, a plurality of reaction kettles, a reaction kettle heat exchanger, a steel belt granulator, a product tank, a material liquid pump and a second raw material mixing kettle; waste sulfuric acid in the waste sulfuric acid tank enters the elevated tank through a sulfuric acid delivery pump, and sulfuric acid in the elevated tank and aluminum hydroxide in the solid feeding pocket are respectively added into the first raw material mixing kettle or the second raw material mixing kettle in a timed and quantitative mode to be mixed into raw material slurry; then the slurry after reaction is melted aluminum sulfate octadecahydrate, and the melted aluminum sulfate octadecahydrate is sent to a steel belt granulator for crystallization granulation and drying, and finally is sent to a product tank for collection. The invention controls the reaction temperature to be higher than the crystallization temperature, so that the system is in a fluid state and cannot be crystallized to block equipment. |
