Abstract

The application discloses a preparation device of slurry subjected to aluminum ash hydrolyzed nitrogen removal pretreatment. The preparation device comprises a support frame, a spraying device and a stirring device, wherein the spraying device and the stirring device are arranged on the support frame, and a conveyor belt is arranged below the support frame; a nozzle is arranged on the spraying device, stirring blades are arranged on the stirring device, and the nozzle and the stirring blades face towards the direction where the conveyor belt is. According to the technical scheme provided by the embodiment of the application, the slurry preparation device has a simple structure and obvious effects, aluminum ash powder can be prepared into aluminum ash slurry through the combination action of the spraying device and the stirring device, the problem that aluminum ash powder floats on water during after-treatment, such as nitrogen removal process, can be avoided, and the treatment efficiency of aluminum ash powder can be improved.

Description

technical field [0001] The present disclosure generally relates to the field of aluminum ash treatment, and in particular relates to a slurry preparation device for aluminum ash hydrolysis denitrogenation pretreatment. Background technique [0002] Aluminum ash, commonly known as aluminum slag, is the general term for scum produced in the aluminum industry. Its main sources include the following two aspects: in the production process of electrolytic alumina process, due to the carrying of operation and measuring equipment, anode replacement, aluminum, casting Ingots and electrolyzers are generated when overhauling. In the production of primary aluminum ingots, aluminum materials, aluminum die castings and castings, and recycled aluminum, smelting and casting are essential and key processes, and a certain amount of aluminum ash will be produced in this process. According to statistics, in 2016, the output of primary aluminum was 32.71 million tons, and the output of aluminum...
