The Importance of Regular Cleaning of Closed Circuit Cooling Towers

Closed circuit cooling towers play an important role in industrial production, but after long-term operation, dirt and impurities will accumulate in the tower, affecting cooling efficiency and equipment life. Therefore, regular cleaning of equipment is key to keeping it running efficiently.

The importance of cleaning
During the operation of the closed circuit cooling tower, the cooling water will come into contact with the air, resulting in the deposition of minerals such as calcium and magnesium ions in the water, resulting in the formation of scale. At the same time, dust, microorganisms, etc. in the air will also enter the cooling system, forming biofilm and dirt. These dirts will be lowered
Heat exchange efficiency, increasing energy consumption, and even leading to equipment failure. Regular cleaning can effectively remove these dirts and restore the performance of the equipment.

Cleaning method
1. Chemical cleaning: use chemical cleaning agents, such as acidic or alkaline cleaning agents, to remove scale and biofilm by circulating cleaning. Chemical cleaning has a remarkable effect, but it is necessary to pay attention to the selection and discharge treatment of cleaning agents to avoid pollution to the environment.
2. Physical cleaning: high-pressure water gun or mechanical brushing is used to remove dirt and impurities in the tower. Physical cleaning is less corrosive to the equipment, but it may require more manpower and time.
3. Comprehensive cleaning: Combined with chemical and physical cleaning methods, chemical cleaning agents are used to soften the dirt first, and then cleaned by physical means. This method works well, but the cost is higher.

Cleaning cycles
The cleaning cycle should be determined based on the frequency of use of the closed circuit cooling tower and the water quality conditions. In general, it is recommended to do a perfect wash every 3-6 months. In the case of poor water quality or high frequency of use, the cleaning cycle should be appropriately shortened.

Maintenance recommendations
In addition to regular cleaning, the following measures should be taken to maintain the equipment:
1. Regularly check the water quality of cooling water, and replenish or replace cooling water in time.
2. Install water treatment equipment, such as softeners, filters, etc., to reduce the formation of scale and impurities.
3. Regularly check the operation status of the equipment, and find and deal with potential problems in time.
Regular cleaning and maintenance of closed circuit cooling towers not only improves cooling efficiency and reduces energy consumption, but also extends the service life of equipment and ensures the smooth operation of industrial production.
