【摘要】：多孔板對于電除塵器內(nèi)氣流均勻起著重要作用,目前已經(jīng)有一些關(guān)于多孔板阻力特性的研究。但是大部分研究集中在低開孔率、少孔數(shù)的多孔板上,而針對電除塵器內(nèi)使用的中高開孔率、多孔數(shù)的多孔板阻力特性研究較少。該文針對開孔率0.3≤?≤0.68,孔數(shù)116≤n≤1567,相對厚度0.21≤t/d≤0.5的多孔板進行了阻力特性研究,旨在得出多孔板的幾何參數(shù)以及管內(nèi)流動狀態(tài)對阻力系數(shù)的影響。試驗發(fā)現(xiàn)阻力系數(shù)均隨著開孔率、雷諾數(shù)、相對厚度的增大而降低,開孔率的影響最為顯著,相對厚度次之,雷諾數(shù)影響最小。文中還提出了估計此類型多孔板阻力系數(shù)的表達式,為今后科學研究及實際應(yīng)用提供了重要參考價值。
[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，
