【摘要】：多孔板对于电除尘器内气流均匀起着重要作用,目前已经有一些关于多孔板阻力特性的研究。但是大部分研究集中在低开孔率、少孔数的多孔板上,而针对电除尘器内使用的中高开孔率、多孔数的多孔板阻力特性研究较少。该文针对开孔率0.3≤?≤0.68,孔数116≤n≤1567,相对厚度0.21≤t/d≤0.5的多孔板进行了阻力特性研究,旨在得出多孔板的几何参数以及管内流动状态对阻力系数的影响。试验发现阻力系数均随着开孔率、雷诺数、相对厚度的增大而降低,开孔率的影响最为显著,相对厚度次之,雷诺数影响最小。文中还提出了估计此类型多孔板阻力系数的表达式,为今后科学研究及实际应用提供了重要参考价值。
[Abstract]:Porous plate plays an important role in the airflow uniformity of electrostatic precipitator. At present, there have been some researches on the resistance characteristics of porous plate. However, most of the researches are focused on the porous plates with low porosity and few holes, but the resistance characteristics of the perforated plates used in the electrostatic precipitators are less studied in the light of the medium and high hole opening rate and the porous number of porous plates. In this paper, the resistance characteristics of perforated plates with opening ratio 0.3 鈮，
