For a long time, people on the circulating cooling water treatment are not very seriously. Is generally believed that the circulating cooling water is only a simple dosing treatment, and through the sewage, add fresh water, to avoid corrosion, scaling and the breeding of micro-organisms on it. However, in fact, the treatment of circulating cooling water is not only related to the safety of production, but also related to the economic operation. A power plant in China has been due to the corrosion of circulating cooling water condenser leakage, a large number of circulating water into the condensate, resulting in a serious deterioration of condensate water quality, resulting in turbine salt and accident shutdown. A petrochemical plant due to serious corrosion of circulating cooling water in less than a year, was forced to replace the 56 heat exchangers, 120 tons of steel consumption, resulting in serious economic losses.
It has been assumed that increased recirculating cooling water treatment equipment and processes will improve operational safety, but that it will significantly increase operating costs because of an increase in investment and operating costs. In fact, the circulating cooling water treatment equipment and process increase, not only improve the safety of operation, but also improve the operation of the economy, this is because the cooling water quality, reducing the amount of sewage, reducing the amount of water, Improve the concentration rate, while reducing the dosage, more importantly, improve water quality, improve the system of corrosion, scaling and the breeding of micro-organisms, the protective effect of the device significantly extended the service life of equipment, reducing the Equipment maintenance, repair and replacement costs. Therefore, in the long run, it is also economical to add processing equipment. According to foreign statistics, the general two years to reach the balance point, after the economic benefits can be generated, because the input is far less than the cumulative consumption.
