Closed cooling tower cleaning method
Most of the cooling water contains calcium, magnesium and acid carbonates. When the cooling water flows through the metal surface, the formation of carbonate. In addition, the dissolved oxygen in the cooling water will cause metal corrosion, Closed cooling tower the formation of rust. Due to the generation of rust, cooling tower cooling effect decreased. Serious when the shell had to spray the cooling water, serious scaling will block the tube, so that the heat loss effect. The data show that scale deposits have a significant effect on heat loss, and as the sediment increases, energy costs increase. Even a very thin layer of scale will increase the fouling part of the equipment more than 40% operating costs. Keep the cooling channels free of mineral deposits can improve efficiency, save energy, extend equipment life, Closed cooling tower while saving production time and costs.
For many years, traditional cleaning methods such as mechanical methods (scraping and brushing), high pressure water, chemical cleaning (pickling) and so on have a lot of problems in cleaning the equipment: can not completely remove the scale and other sediments, acid corrosion caused by equipment to form a loophole , Closed cooling tower The residual acid on the material secondary corrosion or scale corrosion, eventually leading to the replacement of equipment, in addition, cleaning waste water toxic, requires a lot of money for wastewater treatment. In view of the above situation, domestic and international efforts to develop a small metal corrosion of the cleaning agent, and the current successful research and development of the blessing of Tektronix cleaning agent. Its high efficiency, environmental protection, safety, non-corrosive characteristics, not only the cleaning effect is good and no corrosion of the equipment, to ensure the long-term use of closed cooling tower.
