Description

Full-functional circulating water treatment device with rubber ball online cleaning, water cyclone decontamination and electrochemistry
Technical Field
The invention relates to the technical field of industrial circulating water treatment, in particular to a non-chemical full-function circulating water treatment device with the functions of rubber ball online cleaning, water cyclone decontamination, electrochemical desalination, sterilization and corrosion prevention.
Background
The circulating cooling water system is one of the indispensable energy media of air conditioning systems in petrochemical industry, metallurgical industry and building. The circulating cooling water system dissipates heat generated by equipment through heat exchange between water and the atmosphere, so a certain amount of water must be supplemented to make up for the evaporation loss, and various inorganic ions and organic substances in the system are continuously concentrated. In addition, the cooling tower is exposed to sunlight, dust and impurities blown by wind enter the cooling tower outdoors, and the comprehensive effects of various factors such as equipment structure and materials cause three major problems of scaling, corrosion and microorganism breeding in the circulating cooling water system. Dirt and microbial slime can cause under-deposit corrosion, and corrosion products form dirt, and the above-mentioned problems are interrelated and all can cause the heat transfer efficiency of the system to reduce, the water section face reduces, even causes the equipment pipeline to corrode and perforate.
The traditional circulating water system solves the problem by adding chemical water treatment agents, such as scale inhibitors, corrosion inhibitors, bactericides, dispersants and the like. The existing chemical water treatment agents mainly adopt phosphorus systems, are easy to eutrophicate to the water body environment, and any sterilizing algicide has certain biotoxicity, and the regulation in GB50050-2007 design Specification for industrial circulating cooling water treatment specifies that circulating cooling water treated by adding a scale inhibitor, a corrosion inhibitor and the sterilizing algicide cannot be used as direct flow water, so that the circulating cooling water can be discharged after being treated to reach the standard. The salt content in the circulating cooling water with high concentration factor is too high, so that the problems of equipment corrosion, scaling and the like can be caused, the energy loss caused by system blockage and heat exchange efficiency reduction is caused, the water-saving benefit is far exceeded, and in order to limit the concentration factor, a large amount of sewage is discharged to cause waste of water resources. Chemical water treatment agent is high in cost and needs to be maintained by professional personnel, but the problems of scaling, slime and the like in the heat exchanger cannot be completely solved, and the heat exchange tube needs to be cleaned regularly, so that production fluctuation is caused, and the operating cost of system equipment is indirectly increased.
With the high development of industry, the strong demand of human beings on the improvement of the living environment, the sustainable development of society and the related aspects of ecology, environment, resources, economy and the like become the focus of international and social attention, and the traditional treatment mode of taking a chemical water treatment agent as a circulating water cooling water system is increasingly limited by the society and is gradually eliminated, so that a brand new industrial circulating cooling water treatment method and concept are urgently needed at present to meet the development demand of modern industry.
