高频电磁水处理器处理腔的仿真与设计

处理腔是高频电磁水处理器的重要组成部件，为了确定何种处理腔结构对高频电磁阻垢除垢具有更佳的效果，利用Ansoft Maxwell软件建立了有限元模型，对两种常见的处理腔，即同轴电极式处理腔和缠绕电极式处理腔内的电磁场能量分布进行仿真计算，比较了两种处理腔向水体释放电磁能量的大小以及处理腔内观测点的瞬时能量密度的分布特征。仿真分析表明，当施加相同的激励源并处理相同体积的水时，同轴电极式处理腔内的电磁能量远大于缠绕电极式处理腔；但是同轴电极式处理腔内电磁能量分布不均匀，由阳极向阴极依次递减，而缠绕电极式处理腔内电磁能量分布较为均匀。这些结论对于高频电磁水处理器处理腔的设计具有重要的指导意义。

Simulation and design of the processing chamber of high-frequency electromagnetic processor

Processing chamber is an important part of high-frequency electromagnetic water processor. To determine what kind of processing chamber has better effect of antiscaling, the software, Ansoft Maxwell, which is based on the finite element method, is applied to simulate electromagnetic energy distribution in two common processing chambers. One processing chamber is set with coaxial electrodes and the other one is wrapped by spirals. The electromagnetic energy released to water and the distribution of instantaneous energy density of each chamber are compared. According to the simulation analysis, when the same electrical excitation is imposed on the same volume of water, electromagnetic energy of processing chamber with coaxial electrodes is far more than that of processing chamber wrapped by spirals. However, the electromagnetic energy of processing chamber with coaxial electrode decreases from the anode to the cathode, while the electromagnetic energy of processing chamber wrapped by spirals is distributed evenly. These analysis results can be definitely instructive to design the chamber of high-frequency electromagnetic processor.
