交变磁场电磁防垢除垢装置在供冷系统中的应用研究

Application and Research of Alternating Magnetic Field Electromagnetic Anti-scaling Device in Cooling System

由于制冷主机循环水中含有Ca^(2+)和Mg^(2+),冷站冷凝器在运行中很容易出现结垢现象。本文通过在制冷主机管道上安装电磁防垢除垢装置,监测该装置运行后的循环水电导率变化和冷凝器小温差变化,观察制冷主机的宏观腐蚀形貌,最后对水垢进行了表征。结果表明,安装后无需人工排污和化学投药,循环水电导率控制在1000μS/cm,冷凝器小温差保持稳定,材质腐蚀情况较安装前轻。该装置具有良好的防垢除垢作用,为供冷系统的防垢除垢提供参考。

Since the circulating water of the refrigeration host contains Ca^(2+) and Mg^(2+),the condenser of the refrigeration station is prone to fouling during operation.In this paper,an electromagnetic anti-scaling and descaling device is installed on the pipeline of the refrigeration host to monitor the change of the circulating water conductivity and the small temperature difference of the condenser after operation of the device,observe the macroscopic corrosion morphology of the refrigeration host,and finally characterize the scale.The results show that there is no need for manual sewage discharge and chemical dosing after installation,the conductivity of circulating water is controlled at 1000μS/cm,the small temperature difference of the condenser remains stable,and the material corrosion is lighter than before installation.The device has a good anti-scaling and de-scaling function,which provides a reference for the anti-scaling and de-scaling of the cooling system.
