[0002] In the industrial production process, especially in the coal combustion, metallurgy, chemical industry and other industries, a large amount of salt dust is often emitted. These dusts not only cause serious pollution to the environment, but also contain harmful gases such as sulfur dioxide, posing a threat to air quality and human health. Therefore, it is very important to adopt efficient salt dust purification and desulfurization treatment methods.

[0003] At present, when purifying salt-containing dust, it is first necessary to adjust the flue gas temperature and humidity by spraying water or cooling devices to optimize the desulfurization reaction conditions, and then use a wet dust collector to further remove soluble salts in the flue gas to reduce its consumption of desulfurizers and corrosion of equipment. Finally, appropriate desulfurization technology is adopted, such as wet desulfurization, which is to spray limestone slurry to react chemically with sulfur dioxide in the flue gas to generate solid waste such as calcium sulfate. At the same time, the limestone slurry can absorb part of the dust and salt, improve the purification effect, and facilitate the purification of smoke. However, the existing method of adding limestone slurry requires manual addition, which is labor-intensive and easily causes waste of limestone slurry. After the smoke dust is treated, the solid waste generated is not easy to collect and treat, and the treatment efficiency is low.
