【摘要】：饮水机水垢可能引起健康问题,磁化水具有一定的阻垢作用。提出一种固定于饮水机水池外壁的永磁体恒定磁场发生装置,其经济性与易安装维护明显优于工业流体阻垢方法中常见的螺线管恒定磁场装置,同时采用有限元仿真软件COMSOL Multiphysics分析两者圆柱水池内部的磁感应强度分布规律。针对普遍认可的磁场对水体内各种游离离子的洛仑兹力(离子理论)和带电粒子的洛仑兹力(粒子理论)机理进行永磁体实验验证,结果表明:后者强于前者;恒定磁场能够减缓CaCO_3生成,在常温下的阻垢率可达29%;与空白组相比,长期烧水状态下永磁组饮水机的阻垢效果明显。最后,基于pH和钙离子浓度推算了溶液中各个组分的浓度,其中的CaCO_3含量用于阻垢率的计算解决了其难以测量的困难。
[Abstract]:Drinking machine scale may lead to health problems, the magnetized water has scale effect. A fixed on the outer wall of the pool water machine permanent magnet constant magnetic field generating device, its economical and easy to install solenoid constant magnetic field device common maintenance is better than industrial fluid scale method, the finite element simulation software COMSOL Multiphysics analysis the induction strength distribution of both internal cylindrical tank. According to the Lorentz force recognized the magnetic field of the water free ions (ion theory) and the Lorentz force of charged particles (particle theory) the mechanism of permanent magnet experiment results show that the latter stronger than the former; constant magnetic field can reduce the formation of CaCO_3, the scale at room temperature the rate reached 29%; compared with the control group, the scale effect of permanent magnet group drinking machine long on state. Finally, based on pH and calcium ion The concentration of the projections of the concentration of each component in the solution, the content of CaCO_3 which is used to calculate the inhibition rate of the solution is difficult to measure.

【正文快照】： 引言饮水机在使用过程中由于加热、换水以及内部构造等原因会在其内胆和水池中产生严重的水垢问题,一方面易导致肾结石等疾病的产生;另一方面会严重降低热水胆的传热性能,造成能源浪费,缩减饮水机的使用寿命[1-3]。目前家用饮水机的除垢技术主要包括除垢剂清洗法和加压过滤
