The cooling tower (The cooling tower) is the use of water as a coolant, from a system to absorb heat emissions to the atmosphere, in order to reduce the temperature of the device; the cold water is used after contact with the air flow of hot and cold exchange to produce steam, steam heat to heat evaporation evaporation, convection and radiation heat transfer principle to disperse waste heat from industrial or refrigeration and air conditioning to reduce the evaporation temperature of the heat radiating device, in order to ensure the normal operation of the system, device is generally named for the barrel, cooling tower.

The cooling tower is in aerodynamics, thermodynamics, fluid science, chemistry, biological chemistry, material science, static and dynamic mechanical structure, processing technology and other disciplines comprehensive product development. Water quality for multi variable function, cooling is multi factor, multi variable and multi process of comprehensive effect. The following is a cleaning method of cooling tower:

Because most of the cooling water contains calcium, magnesium ions and bicarbonate. When the cooling water flowing through the metal surface, formation of carbonate. In addition, the dissolved oxygen in cooling water will cause corrosion, rust formation. Because of rust, cooling tower heat transfer effect is reduced. Serious when the shell had to spray cooling water, fouling serious when will plug the pipe, so that the loss of function of heat transfer effect. Our data show that effects of scale sediment loss of heat transfer is enormous, with the increase of sediment will cause the increase in energy costs. Even a very thin layer of scale will increase the scale of more than 40% part of operation cost in equipment. Keep the cooling channel does not contain mineral deposits can enhance the efficacy of good, save energy and prolong the service life of the equipment, and save production time and cost.

For a long time the traditional way of cleaning method (such as mechanical scraping and brushing), chemical cleaning, high pressure water (pickling) in the cleaning equipment has a lot of problems: can not completely remove scale deposits, acid corrosion caused by the formation of vulnerability on equipment, the residual acid of the material have two times of corrosion or corrosion under the scale, the final led to the replacement of equipment, in addition, the washing wastewater is poisonous, needs a lot of money for wastewater treatment. In view of the above situation, the domestic and foreign development efforts on cleaning agent for metal corrosion is small, and now developed world blessed Tektronix cleaning agent. It has the advantages of high efficiency, environmental protection, safety, no corrosion characteristics, not only a good cleaning effect and no corrosion to the equipment, to ensure the long-term use of cooling tower.
