Abstract

In order to reduce water consumption (especially in remote areas) for the self-cleaning dust removal systems, the efficiency of a three-phase traveling electromagnetics wave for some designed Electrodynamics Dust Shield (EDS) setups are simulated and also experimentally tested. The designed Fresnel rings electrodes EDS system showed about 25% enhancement on light collecting power and a substantial improvement on dust removal efficiency, as well. On the other hand, for the fabricated EDS systems the dust removal efficiency has been tested as a function of the dust particle size, respectively. In this study, the removal dust particles has been sampled from three different Iran's desserts with a vast size ranges, which matches with many of the remote areas in the world. It was confirmed that the sweeping frequency range from 5 to 100 Hz improved the cleaning efficiency and also the sweeping time lasting reduced about half for the zigzag electrode EDS system in comparison to a simple parallel bar one. For designing the different EDS systems, the well-known Finite Element calculation method (COMSOL Multiphysics software) has been employed, respectively.

电极设计和粉尘粒度对电动力学防尘过程的影响

为了减少自洁除尘系统的水耗(特别是在偏远地区)，对设计的一些电动力防尘罩(EDS)装置的三相行电磁波效率进行了模拟和实验测试。所设计的菲涅耳环电极EDS系统的集光功率提高了25%左右，除尘效率也有了较大的提高。另一方面，对制备的EDS系统的除尘效率进行了测试，分别作为粉尘粒径的函数。在这项研究中，从三种不同的伊朗甜点中取样了去除粉尘的颗粒，这些甜点的大小范围很大，与世界上许多偏远地区相匹配。结果表明，5 ~ 100 Hz的扫描频率范围提高了锯齿形电极EDS系统的清洗效率，并且扫描时间比简单的平行线电极EDS系统缩短了一半左右。在设计不同的EDS系统时，分别采用了著名的有限元计算方法(COMSOL Multiphysics软件)。
