Background technique

With the continuous development of social economy, industrial cooling circulating water and cooling circulating water in central air-conditioning are almost all open cooling circulating water systems. The cooling circulating water evaporates continuously during the circulation process, causing scale ions in the water (such as calcium ions, magnesium ions, bicarbonate lithium ions, calcium carbonate ions, etc.) are continuously concentrated, which will lead to scaling problems in the cooling system, affect heat transfer and cause corrosion problems due to scaling; moreover, the enrichment of nutrients in circulating water will also cause bacteria and algae The reproduction of bacteria will lead to the deterioration of water quality and the formation of biofilm, which will affect the heat transfer and the corrosion caused by microbial metabolism. Therefore, it is necessary to solve the problem of sterilization and descaling of circulating water.

However, the currently commonly used circulating water treatment methods include chemical dosing method or ion exchange method. It will also cause environmental pollution. Moreover, due to the large amount of scaling, manual descaling or other applied chemicals must be used for descaling, which greatly increases the operating cost of the device.

In addition, a Chinese patent with the patent application number "201020550509.2" and the title of the invention "Electronic Box Structure for Electrochemical Water Treatment Devices for Stable Circulating Water Quality" discloses a descaling device. It must be placed in the pool, and at the same time, it is necessary to ensure that the water flow in the pool reaches a certain flow rate, which limits the use conditions, and the treatment effect of the descaling device is not conducive to determination and quantification, making its design and treatment effect uncertain; After the descaling device has been used for a certain period of time, it needs to be taken out of the water to remove the scale. Therefore, in the case of processing cooling water with a large circulation volume, it is necessary to use a crane to take the descaling device out of the water and descale it, which is extremely inconvenient to maintain.

Therefore, it is necessary to propose a semi-automatic circulating water sterilizing and descaling device with better descaling effect and convenient descaling, which can solve the environmental pollution problems caused by chemical descaling in the prior art and improve the performance of water treatment devices. device.
