The function of the cooling tower is refrigeration. Its working principle is: the cooling water carrying heat is exchanged with the air in the tower, and the heat is transferred to the air and dispersed into the atmosphere, so as to provide cooling for the water-cooled chiller. Purpose of water. With a cooling tower, the heat in the water from the water-cooled chiller can be continuously taken away. If the cooling tower's heat dissipation effect is not good, the cooling effect of the chiller will definitely be greatly reduced.
There are two main solutions for cooling tower cleaning. Option 1: Shutdown cleaning; Option 2: Non-stop neutral cleaning.
Option 2: The cooling tower does not stop and uses neutral cleaning
That is, when the cooling tower is in normal operation, the neutral cleaning agent is added to the cooling water and the chilled water system is cycled for about 30 days to release the cleaning liquid, and the cleaning process with the maintenance agent is over. The cleaning time of this solution is relatively long, but it can be carried out under the normal operation of the cooling tower, and it will not affect the normal operation of the cooling tower. Because the cleaning fluid is neutral, it will not cause any corrosion to the system and equipment. During the cleaning process, the dirt in the system will slowly dissolve, and there will be no large scale flakes to block the filter screen after cleaning.
Features of neutral cleaning agent:
1. Neutral cleaning and non-corrosion: The product does not change the pH value of the water after being added to the central air-conditioning water system, and has no corrosion damage to the metal. It completely solves the hidden danger of metal corrosion of the currently commonly used strong acid cleaning agent, and realizes no Corrosion cleaning.
2. High cleaning efficiency: It is effective for all types of scales, especially for insoluble scales such as acid-washed sulfate and algae biological sludge. The scale removal rate is more than 95%, thus restoring the original equipment. Performance, keep the equipment clean and running.
3. Simple operation: Under the condition that the central air conditioner is turned on normally, add a neutral detergent to the water system and run for about 30 days to drain the detergent to completely remove various scales in the water system.
Principle of neutral cleaning:
According to the new theory of coordination field chemistry, the d orbitals of metal ions can be split to form orbitals with different energies under the influence of the electrostatic field of certain ligand compounds. When the ligand gives a lone pair of electrons and the central metal element forms O At the time, if there are empty π molecular orbitals or empty p and d molecular orbitals in the ligand molecule, and the symmetry is appropriate, the lone pair on the d orbital of the central element can form a feedback π bond with the ligand. Thereby forming a stable coordination compound.
Based on the above principles, a compound that can split the Ca2+ and Mg2+d orbitals and has a π molecular orbital is selected as the π-accepting ligand. When this compound interacts with calcium and magnesium scales, it forms stable coordination compounds with Ca2+ and Mg2+d, thereby destroying the molecular structure of calcium and magnesium scales, dissolving them in water and removing them through sewage.
The cooling tower is exposed to the outside for many years, and the fan’s adsorption power is very strong, so that a large amount of sand and dirt will enter the tower. Long-term operation will slowly reduce the cooling capacity of the cooling tower. The water outlet of the water distributor is easily blocked and mud Sand and dirt can also easily enter the cooling water system, which will directly affect the normal cooling of the cooling water system.
