Will The Closed Cooling Tower Scale?

I. Causes of scaling and blockage in the closed cooling tower:

  1. The circulating water is blocked by scaling due to heat. In the process of production and operation, the circulating water is heated and scaling, which reduces the heat transfer efficiency.

  2. Impurities entering the pipe network will cause blockage.

  3. The inner wall of the pipeline rusts, forming rust mud and causing the blockage.

II. Hazards of scaling and corrosion to cooling and heat exchange system:

  1. Significant increase in energy consumption and operating costs.

  2. The working efficiency of the system is reduced, affecting the heating.

  3. Shorten the service life of the equipment. Scaling and slime will seriously affect the normal operation of the system.

Scaling and microbial slime are the main factors affecting the normal operation of the cooling system, which have a great impact on the normal operation and cost operation of the heating system. Therefore, regular cleaning is required. The following purposes can be achieved through cleaning:

  1. Clean up the different scale, microbial sludge, and corrosion products in the circulating water system to ensure the normal operation of the system and high heating efficiency.

  2. Reduce operating costs and greatly save energy. After cleaning, the power or heat consumption of the system can be reduced by about 20%, 6-30%.

  3. Protect and improve the service life of enclosed cooling tower and pipeline equipment, while solving potential corrosion hazards.

III. Heat exchanger cleaning method:

Chemical pickling, including organic and inorganic acids, has long been used in heat exchangers. These chemical cleaning methods cannot solve the problem and cause serious damage to the equipment itself, the human body, and the environment. Based on the idea of reducing energy consumption and protecting the environment, it is suggested to use environmental cleaning agents regularly to clean the scale cleaning efficiency of the heat exchanger.
