Problems solved by technology
However, industrial circulating water and commercial supplementary water contain impurities, such as suspended solids, bacterial substances, etc. If no other preventive measures are taken, even if water treatment chemicals are added, the aforementioned impurities will deposit on the heat exchange surface and cause blockage
Once blocked, it will reduce the heat exchange rate, and even corrode equipment and pipelines, endangering safe production

The invention discloses a cold / hot water treatment device for a closed system, which comprises a closed system cold / hot water storage tank, an upper circulating water pipe, a middle circulating water pipe, a lower circulating water pipe, a primary refrigeration water pump, a secondary refrigeration water pump, a heat exchanger and a zero-dosing water treatment device, wherein the zero-dosing water treatment device comprises a pressure pump, an energy prefilter, a fiber filter and a magnetizer; a water inlet of the energy prefilter is communicated with the closed system cold / hot water storage tank; a water outlet of the magnetizer is communicated with a water inlet of the middle circulating water pipe or heat exchanger; a water inlet of the energy prefilter is positioned before the connecting end of a water outlet of the magnetizer and the middle circulating water pipe; the primary and secondary refrigeration water pumps share one pipe; and the primary refrigeration water pump is positioned before the secondary refrigeration water pump. The cold / hot water treatment device does not need chemical treatment, saves the refrigeration water source and dosing cost, has the advantages of low wastewater discharge amount, energy saving and emission reduction, is beneficial to environment protection, stable operation of the refrigeration water system and reduction of loss of the heat exchanger and pipelines, and prevents the pipelines from blocking and corrosion.
Description
technical field [0001] The invention particularly relates to a cold and hot water treatment (cold or heat recovery) device for a closed system, which belongs to the field of water treatment. Background technique [0002] With the rapid development of the economy and the growth of the population, the problems of water shortage and deterioration of water quality are becoming more and more prominent. Therefore, it is particularly important to save water, do a good job in water treatment, and improve the reuse rate of industrial circulating water and commercial water. [0003] At present, the core issue in the treatment of industrial circulating water and commercial water is to select high-quality and safe water treatment chemicals and use them to control the water quality of circulating chilled water. Therefore, the research and application of water treatment chemicals has always been the current water treatment Hot spot for work. However, industrial circulating water and com...
