【摘要】：電流密度分布是圓形線—板式電除塵器重要的電氣特性之一。為進(jìn)一步弄清圓形線—板式電極極板電流密度的分布規(guī)律,提高該類型電除塵器的除塵效率,有效防止反電暈,文中在異極距(b)為100 mm的條件下,分別測定了同樣極板面積下1~8根電暈線的總放電電流情況;利用Tassicker邊界探頭(BP)法測定電暈線束狀放電點正下方的電流密度分布。結(jié)果表明,總電暈電流隨電暈線數(shù)量增加先增大后減小。當(dāng)外加電壓為40~60 k V、電暈線數(shù)量為2根時總電流值總是最大。單根電暈線束狀放電點正下方的電流密度分布與t分布模型有較好的一致性;雙根電暈線內(nèi)側(cè)電流密度由于電暈線間的放電抑制作用而低于t分布值,雙電暈線外側(cè)電流密度當(dāng)r≥0.4b時與t分布趨于一致,最大電流密度值出現(xiàn)在外側(cè)0.2b附近。
[Abstract]:The distribution of current density is one of the important electrical characteristics of circular wire plate type electrostatic precipitator. In order to further understand the distribution of current density of circular wire plate electrode electrode plate current density, the dust removal efficiency of this type of electrostatic precipitator is improved. In this paper, the total discharge current of 1 ~ 8 corona lines under the same polar plate area is measured under the condition of 100 mm heteropolar distance (b) effectively to prevent back corona. The current density distribution directly below the corona wire bundle discharge point was measured by Tassicker boundary probe method. The total corona current increases first and then decreases with the increase of the number of corona lines, when the applied voltage is 40 ~ 60 kV. When the number of corona lines is 2, the total current value is always the largest. The current density distribution under the single corona line bundle discharge point is in good agreement with the t distribution model. The inner current density of the double corona line is lower than t distribution because of the discharge inhibition between the two corona lines, and the external current density of the double corona line tends to be the same as that of t when r 鈮，
