![]() Therefore, there is a need for a method that can avoid the clogging of the circulating water pipeline due to factors such as algae reproduction, bacterial growth, and metal ion sedimentation. In addition, due to factors such as aging of cooling towers, sudden failures, and rising temperature in summer, the cooling effect of circulating water often fails to meet the requirements, resulting in excessively high water temperature and vaporization of circulating water in the heat exchanger, which is likely to result in forced shutdown. Due to direct sunlight, the proliferation of algae and bacteria will also cause equipment or pipelines to be blocked, posing a threat to production. Most of the circulating pools are placed in the open air. The traditional treatment method is to add scale inhibitor to the circulating water pool, but practice has proved that adding scale inhibitor has poor descaling effect and is not easy to control Therefore, it is necessary to soften the circulating water to avoid scaling. It not only increases the shutdown time, but also shortens the service life of large sets of heat exchangers.Īt the same time, it also affects various production technical indicators When the concentration ratio reaches about 2 times, precipitation occurs, resulting in serious scaling of the circulating water pipeline. ![]() ![]() ![]() In order to ensure its safe operation, circulating cooling water must be used to reduce the temperature of heat exchangers such as copper tiles, large sleeves, conical rings, etc., so that the heat can be dissipated in time to avoid and reduce the occurrence of furnace shutdown accidents.ĭue to the calcium ions and magnesium ions in the water, and the continuous evaporation and heating of the water during operation, Submerged arc furnace is the main production equipment of ferroalloy enterprises, and the furnace temperature is generally above 1800℃. ![]()
