Circulating Cooling Water Scaling Rate, Deposition Rate Monitoring System and Monitoring Method

Abstract

The invention provides a monitoring system and monitoring method for scaling rate and deposition rate of circulating cooling water. The monitoring system includes two loop systems. The loop system where the ultrafiltration equipment is located can separate and remove suspended solids, microorganisms, colloids and other substances from the water, and use the remaining ions to test the scaling rate; the loop system where the electrodialysis equipment is located can The ions in the water are separated and removed from the water outlet, and the deposition rate is tested by using the remaining microorganisms, organic matter, and colloids; the monitoring method calculates the heat transfer coefficient through several sets of test data, and then obtains the expectation of the heat transfer coefficient, and then obtains the mass change and The linear relationship between the heat transfer coefficients, combined with the temperature sensor, flow sensor, and industrial computer, can calculate the scaling rate and deposition rate in real time; the test equipment of the present invention is simple, and the test method is highly theoretical, which fully meets the authenticity and validity of the test data .

Description

technical field [0001] The invention relates to the technical field of industrial circulating cooling water treatment, in particular to a monitoring system and method for monitoring scaling rate and deposition rate of circulating cooling water. Background technique [0002] Water is an important resource for human survival and development, and water is also a limited and irreplaceable resource. In recent years, with the development of the economy, the consumption of water has increased day by day, and the pollution of the global water environment has become increasingly serious. my country is a country with scarce water resources, and the per capita possession of water resources is less than 2,200 cubic meters. Water saving situation is imminent. In the outline of the "Eleventh Five-Year Plan", it is clearly stated that the water intake of major product units in high-energy-consuming industries such as thermal power, steel, petroleum, petrochemical, and papermaking will dr...

AI Technical Summary

Problems solved by technology

For the circulating cooling water system, the static test can determine the degree of fouling, but it cannot fully simulate the state of the circulating cooling water system in the dynamic process

Some manufacturers and research institutes have dynamic simulation equipment, and use dynamic simulation equipment to simulate the operation of the circulating cooling water system. By monitoring the thermal resistance of dirt and calculating the rate of change of thermal resistance of dirt, the rate of dirt deposition can be judged; it is impossible to distinguish the deposits that affect the thermal resistance of dirt Is it due to scaling, microbes, corrosion, inorganic or organic deposits, etc.
