Description
Technical Field
The invention relates to the technical field of circulating water treatment, in particular to a pipeline corrosion and scale inhibition method and a pipeline corrosion and scale inhibition device.
Background
In China, industrial circulating cooling water accounts for more than 70% of industrial water. And because the circulating water is continuously evaporated in the circulating cooling process, the concentration of the salt in the water is continuously increased and exceeds the solubility of certain salts, and precipitation is generated. Common salt precipitates include calcium carbonate, calcium phosphate, magnesium silicate, and other scales. The water scale generated by salt precipitation is relatively compact in texture, the heat transfer efficiency can be effectively reduced, and the heat transfer coefficient can be reduced by 20% by virtue of the thickness of 0.6mm of the water scale. Meanwhile, organic matters, microbial colonies, secretion, silt, dust and the like in water form scale which is soft in texture, so that the heat transfer efficiency of the equipment is reduced, under-scale corrosion is caused, and the service life of the equipment is shortened.
In order to prevent corrosion and scaling caused by the operation of circulating water under high salt concentration and long period, about 2 percent of water flow in the circulating water is generally directly discharged into the ground surface, which causes a great deal of waste. Currently, water treatment agents are still predominant in cooling water conservation and reuse.
Because the phosphorus water treatment agent has low price and better corrosion and scale inhibition performance, the phosphorus water treatment agent still has larger market share in the water treatment at present. However, the phosphorus water treatment agent causes the industrial discharge water to contain a large amount of phosphorus-containing compounds, thereby causing water eutrophication. Phosphorus prohibition and limitation measures are implemented in a large number of countries and regions. The total phosphorus emission concentration of the European Union, the United states, japan, and the like is limited to not more than 1.0mg/L. The national discharge Standard of pollutants for municipal wastewater treatment plants (GB 18918-2002) also stipulates that the total phosphorus concentration of the primary discharge standard is less than 1.0mg/L. After the 90 s of the 20 th century, water treatment agents developed in a direction of being phosphorus-free, easy to recover and environmentally friendly. In recent years, green corrosion and scale inhibitors with few phosphorus and no phosphorus appear, but the corrosion and scale inhibitors have generally weaker performance and generally higher price. The requirement of the treatment of the circulating water of the factory cannot be met.
Therefore, the development of a novel corrosion and scale inhibition method which can meet the treatment requirement of the circulating water of a factory and simultaneously meet the requirement of environmental protection, has better corrosion and scale inhibition performance and is green and pollution-free is an urgent problem to be solved in the circulating water treatment market in the future.
