Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a multifunctional dosing device. Background Art

[0002] The circulating water in the circulating water system is in a continuous circulation process. Due to the increase in water temperature, the water evaporates during the cooling process of the cooling tower, and various inorganic ions and organic substances will be concentrated. The cooling tower and cold water pool are exposed to sunlight, wind and rain, dust, debris and microorganisms, and the interaction between system equipment and water. The combined effect of various factors will cause more serious scale adhesion, equipment corrosion and a large number of microorganisms than the direct current system, which will cause corrosion perforation and leakage of equipment, reduced cooling efficiency, resulting in a decrease in production, and mud and dirt blocking the pipeline.

[0003] At present, in order to ensure that the circulating water can be recycled for a long time, an appropriate amount of corrosion inhibitors and scale inhibitors and bactericides are usually added to the water pool regularly. Corrosion inhibitors and scale inhibitors can slow down the corrosion of heat exchange equipment and pipelines and the deposition of scale. Bactericides can kill bacteria, algae and microorganisms in the water. However, the added agents are easily distributed in the water pool and easily precipitated to the bottom of the pool, causing uneven mixing of the agent and water. As a result, the water entering the circulation pipeline has a low agent content, thereby reducing the treatment effect of the agent on the circulating water, resulting in the problem that the circulating water circulation equipment will still be damaged after long-term use. Utility Model Content
