Description

Technical Field

[0001] The utility model relates to the technical field of processing and recovery devices, and more specifically, to an aluminum ash and ammonia processing and recovery device. Background Art

[0002] Ash is a highly polluting waste generated in the aluminum industry process, including primary aluminum production, aluminum alloy and processing, and scrap aluminum recycling. The composition of aluminum ash is complex and varies slightly due to different production links, raw materials of manufacturers and operating conditions, but it usually contains metallic aluminum, aluminum oxides, nitrides, chloride salts and some other components. Aluminum ash will release ammonia after deliquescence, so it is necessary to use a treatment and recovery device to recover the ammonia before discharging it.

[0003] The current treatment and recovery devices are mostly of closed design. After filtering ammonia for a long time, the filter plate is easily blocked, making it inconvenient to clean it, affecting the circulation of ammonia. At the same time, the ammonia flows too fast in the treatment device, resulting in poor spray treatment effect.

[0008] A plurality of conduits are connected to one side of the top of the movable plate, one end of each of the conduits passes through the box and is located on the top side of the partition, two arc-shaped filter plates are fixedly connected to the box, a first annular tube is fixedly connected to the box through a group of support rods, the first annular tube is connected to the same second annular tube through a plurality of branch tubes, a plurality of atomizing nozzles are arranged at the bottom of the first annular tube and the second annular tube, a water guide pipe is connected to the top of the second annular tube, one end of the water guide pipe passes through the box and is located outside, a hollow plate is fixedly connected to the inner wall of the box, and a plurality of corrugated plates are fixedly connected to the bottom of the hollow plate.

[0009] When using an aluminum ash ammonia treatment and recovery device of the present technical solution, through the joint action of the limit plate, spring, electric push rod and movable block, the electric push rod can be used to squeeze the filter plate. After releasing it, its spring will rebound, causing the filter plate to swing left and right, and impurities attached to it can be cleaned. By setting two arc-shaped filter plates, the ammonia can float upward evenly and dispersedly, increasing the contact area with the spray liquid, extending the residence time of the ammonia in the box, and thereby improving the treatment effect of the ammonia.
