How to clean the air cooler

Because most of the cooling water contains calcium, magnesium ions and acid carbonate. When cooling water flows through the metal surface, there is carbonate formation. In addition, the oxygen dissolved in the cooling water can also cause corrosion of the metal to form rust. Due to the generation of rust scale, the heat exchanger effect of the condenser will drop. Seriously had to spray cooling water outside the shell, the scale will block the pipe serious, so that the effect of heat loss. The data from the study show that scale deposits have a significant impact on the loss of heat transfer, resulting in increased energy costs as deposits increase. Even a very thin layer of scale would increase the operating costs of more than 40% of the scaling in the equipment. Keeping the cooling channels free of mineral deposits improves efficiency, conserves energy and extends equipment life while saving production time and money.
For a long time, traditional air-cooler cleaning methods such as mechanical methods (scraping, brushing), high pressure water, chemical cleaning (pickling) and so on have many problems in cleaning the equipment: the deposits such as scales and the like can not be completely removed, and the acid causes the equipment Corrosion loopholes, the residual acid on the material secondary corrosion or scale corrosion, eventually leading to the replacement of equipment, in addition, cleaning waste toxic, requiring large amounts of funds for wastewater treatment
