磁化除垢影响因素作用规律及其数学模型研究

摘要在交变磁场作用下对碳酸钙进行除垢的影响因素较多，为研究磁场条件下不同工艺因素对碳酸钙结垢的影响规律，研究采用正交方法对饱和碳酸钙溶液进行了磁化试验处理，结果表明：磁化时间和初始钙离子浓度为影响磁化除垢的最显著因素，当磁化时间为0.5 h、电流频率为0.6 kHz、线圈匝数为100圈、c₀（Ca²⁺）为1 000 mg/L、波形为方波时，该条件下磁化溶液的电导率平均值为1.474 mS/cm，与未磁化碳酸钙溶液相比，其电导率增加了0.147 mS/cm，电导率可增加11.45个百分点，除垢效果良好。研究通过回归分析方法建立的磁化除垢作用规律数学模型，可为提高管路的磁化除垢效率提供一定的理论依据，也对工业冷却水系统的除垢问题有重要的参考意义。

Abstract： There are many factors influencing the descaling of calcium carbonate under alternating magnetic field. To investigate the effect of different technological factors on calcium carbonate scaling under magnetic field, the saturated calcium carbonate solution was magnetized by orthogonal method. The results showed that the magnetizing time and the initial calcium ion concentration are the most notable factors affecting the conductivity of magnetized solution. When the magnetizing time was 0.5 h, the current frequency was 0.6 kHz, the coil turns were 100, the c₀ (Ca²⁺) was 1 000 mg/L, and the waveform was square wave, the average conductivity of the magnetized solution was 1.474 mS/cm under this condition. Compared with the unmagnetized calcium carbonate solution, its conductivity increased by 0.147 mS/cm and increased by 11.45 percentage points. It means good scale descaling effect. The mathematical model of magnetic descaling effect established by regression analysis method can provide a theoretical basis for improving the efficiency of magnetic descaling of pipelines, and has important reference significance for descaling of cooling water system.
