The function of the cooling tower is to cool. The working principle is: heat exchange of the cooling water carrying heat in the tower and the air, transfer the heat to the air and disperse into the atmosphere, thereby providing cooling to the water-cooled chiller. The purpose of water. With the cooling tower, the heat in the water from the water-cooled chiller can be continuously taken away. If the cooling effect of the cooling tower is not good, the cooling effect of the chiller will definitely be greatly reduced.


There are two main schemes for cleaning the cooling tower. Solution 1: shutdown cleaning, scheme 2: neutral cleaning without shutdown.


Option 2: The cooling tower is not stopped, and neutral cleaning is adopted.


That is, when the cooling tower is in normal operation, the neutral detergent is added to the cooling water, and the chilled water system is circulated for about 30 days to discharge the cleaning liquid, and the maintenance agent cleaning process is completed. This solution has a long cleaning time, but it can be carried out under normal operation of the cooling tower without affecting the normal operation of the cooling tower. Because the cleaning liquid is neutral, it does not cause any corrosion to the system and equipment. The dirt in the system is slowly dissolved during the cleaning process, and no large scale pieces are blocked after cleaning.


Characteristics of neutral detergent:


1. Neutral cleaning without corrosion: The product does not change the PH value of the water after adding the central air-conditioning water system, and has no corrosion damage to the metal, completely solving the corrosion hazard of the currently used strong acid cleaning agent to the metal, achieving no Corrosion cleaning.


2, high cleaning efficiency: effective for all types of scale, especially for the acid-washed sulfate and other insoluble scales and algae biological slime can also be completely removed, the descaling rate of 95% or more, thus restoring the original equipment Performance to keep the equipment clean and running.


3. Simple operation: Under the normal starting condition of the central air conditioner, the neutral cleaning agent is added to the water system for about 30 days to discharge the cleaning agent to completely remove various scales in the water system.


Neutral cleaning principle:


According to the new theory of coordination field chemistry, the d orbital of metal ions can be split under the influence of the electrostatic field of some ligand compounds to form orbits with different energies. When the ligands give the lone pair electrons and the central metal elements form O. In health, if there is an empty π molecular orbital or an empty p, d molecular orbital in the ligand molecule, and the symmetry is appropriate, the orphan pair on the central element d orbit can form a feedback π bond with the ligand. Thereby a stable coordination compound is formed.


Based on the above principle, a compound capable of splitting the energy level of Ca2+ and Mg2+d orbital and having a π molecular orbital is selected as the π accepting ligand. When this compound acts on calcium and magnesium scales, it forms a stable coordination compound with Ca2+ and Mg2+d, thereby destroying the molecular structure of calcium and magnesium scale, dissolving it in water, and removing it by sewage.


The cooling tower is exposed for a long time, the adsorption force of the fan is very strong, so that a large amount of sediment and dirt enter the tower. The long-term operation will make the cooling tower slowly reduce the heat dissipation capacity, and the water outlet of the water distributor is easy to block, the mud Sand and dirt can also easily enter the cooling water system, which will directly affect the normal cooling of the cooling water system.
