Abstract:

For the spiral winding variable frequency electromagnetic water processor, magnetic induction intensity of water in processing cavity and induced current were analyzed with ANSYS simulation software. The inner relationship of magnetic induction intensity and induced current work with excitation signal frequency was studied. Using an online evaluation test bench for electromagnetic scale inhibition, the influence of spiral winding processing cavity frequency on scale inhibition of hard water circulation heat transfer experiment pipe was observed, and the ideal scale inhibition frequency was determined. Under this experimental condition, the frequency near the line frequency had longer scale induction period and stronger scale inhibition effect, and anti-scaling efficiency was the best.

Key words: spiral winding processing cavity, frequency, magnetic induction intensity, induced current, anti-scaling effect, convection, heat transfer, numerical analysis

摘要：

针对缠绕式变频电磁水处理系统,利用ANSYS仿真软件对处理腔内水溶液的磁感应强度和感生电流进行分析,探究水体内磁感应强度以及感生电流做功与激励信号频率的内在关系,并利用电磁抑垢效果在线评价实验台,通过改变缠绕式处理腔中电磁场的频率大小分析其对特定硬水循环换热实验管道抑垢效果的影响规律,进而寻求理想的抑垢频率。实验结果表明,电磁频率在分界频率附近时水处理系统能到达较长的污垢诱导期以及较好的抑垢率,抑垢效果最佳。
