摘要
作者回顾了粒子驱进速度的研究现状,指出了各种驱进速度的相互关系,概述了粒径及紊流流动对粒子驱进速度的影响。通过分析认为,对于单区式电除尘器,可用多依奇公式计算除尘效率;对于双区式电除尘器,粒子的理论驱进速度大于实际驱进速度。
The present situation of the migration velocities of particles is reviewed. The relationship among the migration velocities are given and the influence of the particle size, the particle charges and turbulence on the migration velocities are discussed. The results demonstrate that the Deutsch equation can be used to calculate the collection efficiency of the single-zone electrostatic precipitator and that the theoretical migration velocity is larger than the actual one in double-zone electrostatic precipitator.
