Abstract：Electrochemical descaling equipment is widely used in the industrial field,but its low de-scaling effect affects its application.To improve the working efficiency of electrochemical descaling e-quipment,a descaling device test platform for descaling machines has been established.By examining the changes in water quality parameters(conductivity,hardness)before and after experiments,this article analyzed the impact of different voltages,currents,water flow rates,and temperatures on the descaling efficiency of the descaling device.The research findings reveal that the electrochemical de-scaling device significantly reduced the conductivity and hardness of the solution,exhibiting optimal descaling performance under conditions of 30℃temperature,0.35 m/s flow rate,24 V voltage,and 10 A current.Through qualitative and quantitative analysis of scale samples using XRD(X-ray dif-fraction)and SEM(scanning electron microscopy),it was found that the calcite in the CaCO3 scale sample transformed into aragonite,and the content of aragonite increased.Research can provide refer-ence for improving the descaling effect of descaling machines.
