Description

Circulating water treatment device for producing silicon-chromium alloy Technical Field The application relates to the technical field of silicon-chromium alloy production, in particular to a circulating water treatment device for silicon-chromium alloy production. Background In the production process of the silicon-chromium alloy, particularly in the electric furnace smelting stage, equipment (such as an ore-smelting furnace, a transformer, a pneumatic compression station and the like) used for producing the silicon-chromium alloy needs to be cooled, and the cooling mode generally adopts circulating cooling water to exchange heat with the equipment so as to realize the cooling of the equipment, so that the normal operation of the equipment is ensured. However, in the process of heat exchange between the circulating cooling water and the cooling device, hardness ions such as calcium ions and magnesium ions are commonly present in water or tap water in nature. Therefore, as the temperature of the circulating cooling water increases during the process of cooling the equipment by the circulating cooling water, the concentration of hardness ions such as calcium ions and magnesium ions contained in the circulating cooling water gradually increases due to evaporation of the circulating cooling water, so that the hardness of the circulating cooling water increases, and as the hardness of the circulating cooling water increases, the circulating cooling water may cause scaling of various pipelines and the like through which the circulating cooling water flows during the circulation process, so that the cooling effect of the circulating cooling water on the equipment is affected. The prior process for reducing the hardness of the circulating cooling water, which is mature or common in industrial application, adopts chemical reagents, namely inorganic matters or organic matters are added to slow down the formation of scale or prevent the formation of scale, so that the hardness of the circulating cooling water is reduced, but the use of the chemical reagents can cause secondary pollution to water, so that the circulating cooling water cannot be directly discharged and can be discharged after purification treatment, and the treatment cost of the circulating cooling water discharge is increased.
