【摘要】 本文比较系统地研究了不同形状、尺寸的收尘极板电流密度分布及背部涡流结构,其结果表明:板型、板宽及回风沟槽高度对电流密度分布具有很大的影响;板宽对背部涡流结构具有明显的影响;而板型及回风沟槽高度对背部涡流几乎没有影响.通过比较分析,选出了一种比较理想的极板形状和尺寸.更多还原

【Abstract】 The distribution of current density and the structure of vortex flow at the back of the collection plates in different shapes and sizes are systematically investigated.The results show that the shape and width of the plate and the height of the return-air groove significantly affect the distribution of current density that the width alone noticeably affects the vortex flow structure and that the shape of the plate and the height of the return-air groove have little affect on the vortex flow structure. Through comparison and analyses, the shape and size of the plate are optimized.更多还原
