Background

At present, the existing circulating water cooling mainly comprises: 1. a direct current cooling water system; 2. an open circulating cooling water system; 3. closed air cooling recirculating cooling water system. The direct current cooling water system and the open type circulating cooling water system have the advantages of large water evaporation capacity, high maintenance cost, high pollution discharge amount, scaling corrosion of process heat exchange equipment and large fluctuation of outlet water temperature. The closed air cooling circulating cooling water technology, the direct current cooling water system and the open circulating cooling water system have the following advantages of 1, and low consumption of fresh make-up water. According to production practice, compared with the traditional industrial circulating cooling water system of a water cooling tower, the water can be saved by more than 50%. 2. The cooling water has stable temperature and meets the technological requirements. Due to the fact that a plurality of measures for adjusting the temperature are provided, the temperature of the cooling water out of the air cooler can be guaranteed to be stable. 3. The heat exchange efficiency of the heat exchange equipment is improved, and the heat exchange with the process heat exchange equipment is realized by soft water, which has low hardness, less impurities, pH value of 7-9, slight alkalinity and closed cycle in a system and is not polluted by the atmosphere. Greatly reduces the scaling and corrosion of the process heat exchange equipment, improves the heat transfer efficiency of the process heat exchange equipment and prolongs the service life of the process heat exchange equipment. 4, less sewage discharge and environmental protection. If the same concentration ratio is adopted for pollution discharge, the evaporation capacity of the closed air cooling system is only 50% of that of the cold water tower system, so the pollution discharge capacity is reduced by nearly 50%. Is beneficial to environmental protection and saves sewage treatment investment. 5. The total occupied area is small. 6. Simple maintenance and low operation cost. No filler, no need of replacement, reduced cost and labor hour. The dosage is less, and the dosage cost is only 50 percent of that of the cooling tower system. And the water and electricity are saved, and the operation cost is low. 7. The construction scale of water taking engineering of water source areas is reduced, and the water delivery investment is reduced. However, the closed air-cooled circulating cooling water system also has some problems, especially the scaling problem of spray water. Along with the volatilization of the spray water, the concentration of calcium, magnesium and other ions of the spray water in the water collecting tray is higher and higher. The dissolved salts in the feed water are concentrated during the circulation process to precipitate insoluble salts such as CaCO3, which causes scale damage. The reason why the scale is generated in the supersaturated solution of the sparingly soluble salt in the spray water is not only concentration of the salt in the circulating water but also local concentration of the salt on the surface of the heat transfer tube of the heat exchanger and lowering of the solubility of the quasi-soluble salt due to increase of the water temperature and the pH. The formation of locally supersaturated solutions is of significant concern in relation to the actual occurrence of scale damage. The scale has wrapped a thick layer over the coil. Such coils may have reduced heat exchange efficiency.
