【摘要】：静电旋风除尘器的除尘效率高,占地面积小,安装方便,得到了广泛的应用。比较了接地极雾化电晕放电旋风除尘器,静电旋风除尘器和传统旋风除尘器的放电特性、捕集效率、分割粒径、分级效率和对高比电阻的适应能力。研究表明:首先,流量为80 m L/min时,接地极雾化电晕放电旋风除尘器的起晕电压和放电电流均优于静电旋风除尘器;其次,接地极雾化电晕放电旋风除尘器的分割粒径和分级效率都明显优于静电旋风除尘器,而分级效率更是较传统旋风除尘器提高了15%以上。最后,当粉尘的比电阻增大时,接地极雾化电晕放电旋风除尘器的收集效率保持稳定,几乎不随工作时间改变,而静电旋风除尘器的效率则随着工作时间的增加而降低。因此,接地极雾化电晕放电技术更有利于高比电阻粉尘的捕集,应用前景广阔。
[Abstract]:Electrostatic cyclone dust collector has high dust removal efficiency, small area, easy installation, and has been widely used. The discharge characteristics, capture efficiency, partition particle size, classification efficiency and adaptability to high specific resistance of ground electrode atomized corona discharge cyclone dust collector, electrostatic cyclone dust collector and traditional cyclone dust collector are compared. The results show that, firstly, when the flow rate is 80 mL / min, the corona discharge cyclone dust collector with ground electrode atomization is superior to the electrostatic cyclone dust collector in the starting voltage and discharge current. The particle size and classification efficiency of ground electrode atomization corona discharge cyclone dust collector are obviously superior to electrostatic cyclone dust collector, and the classification efficiency is more than 15% higher than that of traditional cyclone dust collector. Finally, when the specific resistance of dust increases, the collection efficiency of ground electrode atomization corona discharge cyclone dust collector remains stable and almost does not change with working time, while the efficiency of electrostatic cyclone dust collector decreases with the increase of working time. Therefore, the earth electrode atomization corona discharge technology is more favorable to the capture of high specific resistance dust, and has a broad application prospect.
