Abstract:

The effect of magnetic field on the CaCO₃ precipitation with different treated flow rates has been studied with the system which could measure the pH and the concentration of Ca²⁺ of the supersaturated calcium carbonate solution. The quantitative experimental data reveal that the scale could be reduced with the effect of magnetic treatment and the effect of the antiscale in different flowrate is different. In constant exposure time and within our concerned velocity scope in the range of 0~6 m/s, the higher flowrate, the better effect on antiscale.

Key words: low rate, antiscale, calcium carbonate, magnetic treatment

摘要：

利用双道的实时监测系统，通过监测碳酸钙过饱和溶液中的pH和Ca²⁺浓度在析晶过程中的变化，系统的研究了不同流速下磁场的阻垢效果。准确、可重复的试验数据表明，磁场对碳酸钙过饱和溶液有阻垢效果，并且不同流速下磁场的阻垢效果不同。同时试验结果还表明在磁处理时间恒定的条件下，在0～6 m/s的流速范围内，溶液通过磁场的流速越高磁处理的阻垢效果越强。
