Application Characteristics of Self-Cleaning Filters in Circulating Water

Circulating cooling water is a major water use in industrial water consumption. In industries such as petrochemical, electric power, steel, and metallurgy, the use of circulating cooling water accounts for 50% to 90% of the total water consumption of enterprises. In industrial production, as the operating cycle extends and the concentration factor increases, factors such as suspended substances and dust caused by microbial growth lead to changes in water quality, resulting in frequent problems such as heat exchanger scaling, corrosion, and continuous accumulation of impurities and suspended solids in pipelines, which form solid substances. These issues increase energy consumption, reduce equipment service life, and create safety hazards. Different supplementary water sources affect the cycle and severity of these problems. How to reasonably control water quality parameters to improve water reuse rate, save water resources, and greatly improve the overall condition of circulating cooling water is crucial. Self-cleaning filters can effectively remove accumulated impurities in the water, significantly reducing energy consumption; secondly, self-cleaning filters achieve online cleaning without interrupting flow, ensuring system flow throughout the circulation system; thirdly, self-cleaning filters require no manual operation, especially for some high-temperature water, greatly reducing labor intensity and risk; fourthly, self-cleaning filters can be remotely monitored and controlled online through PLC systems, facilitating the inspection of system stability. It is also necessary to establish effective monitoring methods for circulating cooling water systems, monitor water quality stability online, and accurately control the dosing of circulating water chemicals. Intelligent monitoring technology and data acquisition systems have made significant progress, and by calculating the scale inhibitor's inhibition rate, the scale inhibition effect can be evaluated. A method for evaluating the scale inhibition effect of water treatment technology before scale prevention technology evaluation has been proposed. Despite various tests and selections, online optimization of on-site water treatment schemes has not been completed.
