摘　　要：提出了电磁式静电除尘空气净化法。从带电粒子的电漂移理论出发 ,阐明了加平行磁场较加垂直磁场能得到更高的净化效率的理论依据。在更深一步的试验研究基础上 ,提出粒子初速存在着一个提高净化效率的最佳值 ,并应用带电粒子电漂移理论解释了一定的集尘板间距内加垂直磁场后 ,净化效率低于不加磁场情况下的净化效率这一特殊现象 。The air purification technique of electrostatic removal of particle in electromagnetic field is presented novelly by authors.Starting from the electric drift theory of charged particles, it is explained that the theoretical base of purification efficiency can be increased more distinctly by applying parallel magnetic field than by applying perpendicular magnetic field. Based on further experiments, it is presented that there is an optimal initial velocity of charged particles to reach higher purification efficiency. It is explained on base of the electric drift theory of charged particles that the purification efficiency is lower by applying perpendicular magnetic field than without applying magnetic field under the special distances between collecting plates so as to perfect this new technique.
