A new online monitoring and evaluation device for the treatment countermeasures of circulating cooling water was developed,which is used for evaluation and optimization of water treatment countermeasures, and online monitoring of the core water quality parameters. This device can online monitor the heat exchanger fouling resistance, corrosion rate and core water quality parameters (pH, ORP, concentrated ratio) in real-time based on the fluid state, water quality, metal materials and heat transfer intensity of the power plant circulating cooling water, and can evaluate and adjust the concentration of the water treatment agent online. The monitoring system hardware including fouling resistance detector, corrosion rate detector, automatic dosing device, analysis instrumentation of water quality parameters and industrial computer was designed. And the software was developed by Delphi7.0 which can carry out monitoring parameter settings, real-time display, online control, historical data query and report printing. This device has been used in Unit 1 of the Power Plant of Shandong Yancon Croup Co., Ltd. The experimental results showed that the instantaneous fouling resistance and corrosion rate were less than 1.5×10?4 m2·K·W?1 and 0.005 mm·a?1, respectively, and the concentration ratio of the circulating cooling water can increase from 2 times to 4 times. This device can evaluate the water treatment dosing <br> programs in real-time, inhibit the growth of fouling resistance effectively, reduce the corrosion of the heat exchanger and improve the economic efficiency of power plants.
