Air cooler cleaning method is because the cooling water mostly contains calcium, magnesium ions and acid carbonate. When cooling water flows over the metal surface, carbonates are formed. In addition, the oxygen dissolved in the cooling water can cause metal corrosion and form rust. Due to the generation of rust, the heat exchange effect of the condenser is reduced. In severe cases, cooling water has to be sprayed outside the shell. In severe cases, the tube will be blocked and the heat exchange effect will be lost. Research data shows that scale deposits have a huge impact on the loss of heat transfer, and the increase in deposits will increase energy costs. Even a thin layer of scale will increase the operating cost of the scaled part of the equipment by more than 40%. Keeping the cooling channel free of mineral deposits can improve efficiency, save energy, extend the service life of the equipment, and save production time and costs. For a long time, traditional cleaning methods such as mechanical methods (scraping, brushing), high-pressure water, chemical cleaning (pickling), etc. have encountered many problems when cleaning the equipment: they cannot completely remove deposits such as scale, and the acid causes corrosion to the equipment and forms loopholes. , The residual acid will cause secondary corrosion or under-scaling corrosion to the material, which will eventually lead to the replacement of equipment. In addition, the cleaning waste liquid is toxic and requires a lot of money for wastewater treatment.
