Study on performance of the compound filter with electrostatic spray and wet metal filler
摘要：
通过对喷雾荷电团聚机理和湿式金属填料过滤机理的研究，开发了一种静电喷雾湿式金属填料复合过滤器。介绍了该复合过滤系统试验装置。分别对干式金属填料、湿式金属填料、高压喷雾以及荷电喷雾4种过滤方式进行了试验。试验结果表明当风速1.2 m/s、填料喷淋量1.0 m3/h、荷电喷雾量60 L/h、荷电电压10 kV、环嘴距20 mm时，复合系统的过滤效率最高。
Abstract：
Based on the study of the spraying charge agglomeration mechanism and the wet metal fill filtration mechanism, develops the high efficient electro-spray wet metal filler compound filter. Presents the experiment devices of the compound filter system. Performs the experiment on four different filtering modes of dry metal filler, wet metal filler, high pressure spray and electrostatic spray. The test results show that the compound filtration system has the largest filtration efficiency under the condition with air velocity 1.2 m/s, sprinkling rate 1.0 m3/h, spray volume 60 L/h, charged voltage 10 kV, and distance between electrode ring and nozzle 20 mm.
