Abstract

Electro-cyclones allow simple and cost effective removal of fine particles by improving the collection efficiency of conventional cyclones with the application of external electric fields. However, understanding of design and operational parameters for optimizing the performance of electro-cyclones are still limited due to the complexity of the removal mechanism and the lack of prediction models. In this study, the particle collection efficiency of electro-cyclones has been analyzed using simple theoretical models, and the system configuration of multiple electro-cyclones has been evaluated especially for the removal of fine particles less than 5 µm which are limited in conventional cyclones. Based on the Stairmand high efficiency cyclone design, the effects of external electric field on a single and multiple units were investigated. Parallel operations of multiple electro-cyclones, consisting of 10 units, potentially provided the cut off diameter less than 0.3 µm by lowering flow rate and operation load for each unit. For a multiple configuration, the collection efficiency was improved as the number of units increased, while the flow speed variation due to the parallel operation was insignificant.

多电旋流器系统设计的性能预测模型

电旋风通过应用外部电场提高传统旋风的收集效率，可以简单而经济地去除细颗粒。然而，由于去除机制的复杂性和缺乏预测模型，对优化电旋风性能的设计和操作参数的理解仍然有限。在本研究中，使用简单的理论模型分析了电旋风的颗粒收集效率，并评估了多个电旋风的系统配置，特别是对于传统旋风中限制的小于5µm的细颗粒的去除。以Stairmand型高效旋风分离器设计为基础，研究了外加电场对单机组和多机组的影响。由10台组成的多台电旋风并联运行，通过降低每台电旋风的流量和运行负荷，有可能使截止直径小于0.3µm。对于多机组配置，随着机组数量的增加，收集效率有所提高，而并联运行引起的流速变化不显著。
