Experimental Study on the Performance of a New Type of Self-Priming Scaling Evaporative Condenser
In order to solve the easily scalable problem of evaporative condensing equipment, re-search was conducted on the development of a new type of self-priming scaling evaporative condenser with a built-in electrochemical scale absorber which changes the traditional water quality treatment cycle method from “preventing scaling” to “self-priming scaling”, integrating treatment devices and an evaporative condenser in order to realize the integration and modularization of the equipment. Experimental results show that the new self-priming scaling evaporative condenser has a condensing temperature range of 36.7~38.9 °C, heat rejection range of 716.69~768.66 kW, and, under different load rates, a condensing temperature range of 22.7~36.7 °C. The new self-priming scaling evaporative condenser system’s energy efficiency ratio COP has a range of 3.26~3.44. The coefficient of performance IPLV is 3.9, which exceeds the design index value. After the unit ECT electrochemistry meter is turned on, it effectively reduces the concentration multiplier of water quality: the total hardness increase per minute is reduced from 0.4 mg/L to 0.23 mg/L, a reduction of 42.5%. Turning on the electrochemistry meter also effectively reduces the increase in the total hardness and reduces the occurrence of scaling in the evaporative condenser unit.
