Is the service life and efficiency of closed cooling towers related to water quality?
As the water quality of cooling water, although there are no strict restrictions on various indicators like process water and boiler water, in order to ensure stable production, no damage to equipment, and long-term operation, the water quality requirements for cooling water are still quite high.
As the water quality of cooling water, although there are no strict restrictions on various indicators like process water and boiler water, in order to ensure stable production, no damage to equipment, and long-term operation, the water quality requirements for cooling water are still quite high.
Oasis ice peak: the following detailed explanation of the following points
01, the water temperature should be as low as possible.
Under the same equipment conditions, the lower the water temperature, the lower the daily output and the higher the daily output. For example, when a chemical fertilizer plant produces synthetic ammonia, it is necessary to cool the gas from the compressor and the tower. The lower the temperature of the cooling water, the higher the ammonia output of the synthetic tower.
The lower the temperature of the cooling water, the corresponding reduction in water consumption, such as the pharmaceutical factory in the production of streptomycin, the need to use water to cool streptomycin concentration equipment and solvent recovery equipment, if the water temperature is higher, then the water consumption is less.
02, the turbidity of water should be low
Suspended solids in the water brought into the cooling water system will be deposited in the heat exchange equipment and pipes due to the reduction of the flow rate, which will affect the heat exchange, and the pipes will be blocked in serious cases. In addition, the turbidity is too high will accelerate the corrosion of metal equipment, for this reason, in some large foreign fertilizer, chemical fiber, chemical and other production systems for cooling water turbidity requirements shall not be greater than 2mg/L.
03, water quality is not easy to scale
During the use of cooling water, it is required that it is not easy to form scale on the heat transfer surface of the heat exchange equipment, so as not to affect the heat exchange effect. This is a key to the safe production of the factory. The production practice shows that due to poor water quality, it is easy to form scale. Examples of affecting factory production are not uncommon.
04, water quality is not easy to produce corrosion of metal equipment
In the use of cooling water, it is required not to corrode metal equipment. If corrosion is inevitable, the less corrosion is required, the better, so as to avoid rapid reduction of effective heat area or premature scrap due to rapid corrosion of heat transfer equipment.
05, water quality is not easy to breed bacteria and algae
During the use of cooling water, it is required that microorganisms such as bacteria and algae are not easy to breed in the water, which can avoid or reduce the formation of a large amount of slime dirt due to the reproduction of bacteria and algae. Excessive slime dirt will cause pipeline blockage and corrosion.
