利用静电旋风除尘器捕集亚微米粒子的研究

RESEARCH ON COLLECTING SUBMICRON PARTICLE BY ELECTROSTATIC CYCLONE

利用高场强静电旋风除尘器捕集柴油机排放的亚微米粒子,通过实验证实了,静电旋风除尘器可以有效捕集亚微米粒子。提出了对于该静电旋风除尘器,粒子的有效驱进速度与进口风速的关系式,这对于发展捕集亚微米粒子的静电旋风除尘器具有一定的参考价值。为控制柴油机的颗粒物排放提供了一个新的思路。

The article employs a high field strength electrostatic cyclone to collect submicron particle of diesel exhaust,the test results show that the electrostatic cyclone can collect submicron particle efficiently.An equation for the cyclone about the particle effective migration velocity ω e and the inlet velocity has been introduced,which is beneficial to developing electrostatic cyclone to collect submicron particle.The article also provides a new thinking to control the diesel particulate emission.
