Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water treatment equipment, in particular to a water-saving device suitable for a circulating cooling water system. BACKGROUND

[0002] With the increasingly severe global water resource shortage problem, water-saving technology has become the focus of attention in various industries. As an important part of industrial water, the operating efficiency of the circulating cooling water system not only affects the operating cost of the factory, but also directly relates to its environmental performance. Although the circulating cooling water system on the current market has certain recycling ability, there are still many challenges in actual operation. The problems of scale and corrosion lead to continuous deterioration of water quality, not only increasing the system maintenance cost, but also significantly increasing energy consumption, thereby affecting production efficiency.

[0003] To cope with the scale and corrosion problems of the circulating cooling water system, the market generally adopts two solutions of physical method and chemical method. The physical method removes scale in the pipeline through high-frequency vibrator, ultrasonic wave and other means, which can effectively remove existing deposits, but has limited effect on preventing the formation of new scale. The chemical method prevents scale formation and protects the metal surface by adding scale inhibitors, corrosion inhibitors and other chemicals, but this method can easily cause environmental pollution problems, and long-term use may lead to deterioration of water quality. Both methods have advantages and disadvantages, but it is difficult to fundamentally solve the core problem of the circulating cooling water system.

[0004] Although the physical method and the chemical method can alleviate the scale problem to some extent, their application in large-scale cooling water systems still has many shortcomings. These methods are complex to operate and have high operating costs, making it difficult to maintain the efficient and stable operation of the system for a long time, thereby restricting the improvement of overall economic benefits. Therefore, there is an urgent need for an innovative solution that can integrate the advantages of existing methods while overcoming their limitations, achieving a comprehensive breakthrough in water saving, cost reduction and environmental protection, and providing technical support for the sustainable development of industrial circulating cooling water systems.
