Embodiment 1

[0021] by figure 1 It can be seen that the present invention is a method for improving the deposition of metallurgical solution crystals in the air cooling process. The described method is to use the metallurgical solution after cooling the air cooling tower to be transported to the upper part of the air cooling tower by a conveying device, and then flow down through the inner wall surface of the tower barrel to form a liquid flow film covering the inner wall surface of the tower barrel to spray The cooling liquid droplets that reach the inner wall of the tower barrel cannot directly fall on the surface of the tower itself, but fall into the liquid flow film on the inner wall surface of the tower barrel, thereby preventing the droplet crystals from depositing on the inner wall of the tower barrel; at the same time, it can also cool the tower. The cooled metallurgical solution is irradiated with ultrasonic waves to refine the crystal grains in the air-cooled metallurgical solutio...

Embodiment 2

[0025] figure 2 This is another embodiment of the present invention. From figure 2 It can be seen that this is an ultrasonic air cooling tower 24 that improves the crystal deposition of metallurgical solution in the air cooling process. The ultrasonic air-cooling tower 24 includes a tower barrel 11, a tower tank 18, a spray device 3, a drip catching device 2, an air blowing device 12, and a liquid flow film forming device 6. The liquid flow film forming device 6 includes ultrasonic Wave source device 23. The principle of the second embodiment is the same as that of the first embodiment, except that the metallurgical solution 19 after air cooling has a frequency of 15-128kHz and a sound intensity of 0.5-50w / cm 2 After direct or isolated irradiation of the ultrasonic wave, it is transported to the circumferential liquid distribution device 7 by the conveying device 15 through the pipeline 16, and then uniformly distributed to the inner wall surface of the tower 11 by the circ...

Embodiment 3

[0027] figure 1 It is another embodiment of the present invention. The principle of the third embodiment is the same as that of the first embodiment, except that the metallurgical solution 4 becomes zinc sulfate solution 20, and the metallurgical solution outlet 17 after air cooling becomes zinc sulfate after air cooling. At the solution outlet 21, the air-cooled metallurgical solution 19 becomes the air-cooled zinc sulfate solution 22. The zinc sulfate solution air cooling tower is used in the wet zinc metallurgical production process, and can greatly improve the crystal deposition of the zinc sulfate solution 20 on the inner wall surface of the tower 11 during the air cooling process.

Abstract

The invention relates to an air cooling tower and a method for improving the crystallization and the sedimentation of metallurgical solution during air cooling process. Metallurgical solution cooled by the air cooling tower is conveyed to the inner upper part of the air cooling tower by a conveyer and then downwards flows along the surface of the inner wall of a tower cylinder to form a liquid film covering the surface of the inner wall of the tower cylinder so that temperature reducing droplets sprayed to the inner wall of the tower cylinder fall into the liquid film on the surface of the inner wall of the tower cylinder but not directly fall to the surface of the tower cylinder so as to prevent droplets from crystallizing and being sedimentated on the inner wall of the tower cylinder; meanwhile, ultrasonic radiation can also be carried out on metallurgical solution cooled by the air cooling tower to refine crystal grains in the air-cooled metallurgical solution; the treated metallurgical solution is conveyed to the inner upper part of air cooling tower and downwards flows along the surface of the inner wall of the tower cylinder to form a liquid film with refined crystal grains, and the liquid film is covered on the surface of the inner wall of the tower cylinder to prevent crystal grains in the liquid film from being sedimentated on the surface of the inner wall of the tower cylinder.

Description

Technical field [0001] The invention relates to a method and device for cooling a metallurgical solution, in particular to a method and device for improving the crystal deposition of a metallurgical solution in an air cooling process, and belongs to the technical field of air cooling. Background technique [0002] The temperature of the metallurgical solution in the metallurgical process is generally cooled by an air cooling tower (ie, an air cooling tower). During the cooling process of the air cooling tower, certain material components in the metallurgical solution cause precipitation and crystallization due to cooling, and the crystals are deposited on the surface of the inner wall of the equipment, reducing the operating efficiency of the equipment. For example, the zinc sulfate solution produced in the purification process of wet zinc metallurgy and the electrowinning process is also cooled by an air cooling tower. The zinc sulfate solution is scattered from the top of the a...
