The common ones are physical cleaning of the cooling tower circulating water system and chemical cleaning of the cooling tower circulating water system. If the fouling exceeds 3mm, it is recommended to use the cooling tower circulating water system for chemical cleaning, or even to carry out physical blasting treatment after chemical cleaning.
1. Physical cleaning of cooling tower circulating water system:
The physical cleaning of cooling towers circulating water system mainly uses the scouring effect of water flow or the brushing, wiping and scraping functions of appliances to remove sediments in equipment and pipelines. The main methods of physical cleaning are: high pressure water cleaning and appliance cleaning.
① High-pressure water cleaning: High-pressure water cleaning is a method of cleaning the surface to be cleaned by using a powerful jet of high-speed water to act on the surface to be cleaned at a certain... less

The cooling tower basically belongs to the heat exchange equipment system, and the two media for heat exchange are: water and air. The whole process is the joint action of contact heat dissipation and evaporative heat dissipation to cool the water, which is the process of evaporative cooling. Contact heat dissipation (heat transfer) - because there is a temperature difference when water and air are in contact, Tw>Ta, the air takes away part of the heat of the water, causing the water temperature to drop. Evaporative heat dissipation (mass transfer)-The water vapor formed by the evaporation of the water surface continuously diffuses into the air, and at the same time, the latent heat of vaporization of the water is brought into the air, and the water evaporates and absorbs heat to reduce the temperature of the remaining water.

Then the cooled circulating water is sent to the heat source by the circulating pump of the system. External circulating water system: The spray water is sent from the lower water tank to the upper water distribution pipe by the spray water pump, and the water spray contact with the heat exchanger pipe. Part of the water in evaporation with heat, and these heat is dis-charged by the top fan, and water vapor is blocked back by the special structure of the de-hydrator then fall into the collection tank to circulate again.
