A new approach to electrostatic precipitation is proposed that utilizes electrostatically charged heavy solid particles which are sustained in suspension between parallel walls of the precipitator with a dc applied electric field. These particles, which are larger by a factor of 102 to 104 then the dust, will scrub a flowing dust laden gas as a result of impaction and electrostatic attraction to the solid particles. The solid particles are continuously swept through the precipitator in a cross-flow motion relative to the flowing dirty gas and are made to undergo a self-cleaning action by collision with the boundary wall of the precipitator where they receive at either of the parallel walls of the precipitator from the action of the applied electric field. Alternatively, the "dust carrying" solid particles can be allowed to pass out of the precipitator for washing while a makeup of clean solid particles is supplied. In either case, the process is continuous in a dc electric field.

提出了一种静电除尘的新方法，该方法利用带静电的重固体颗粒，这些颗粒在施加直流电场的情况下保持悬浮在除尘器的平行壁之间。 这些颗粒比灰尘大 102 至 104 倍，由于对固体颗粒的冲击和静电吸引，它们将擦洗流动的含尘气体。 固体颗粒以相对于流动的脏气体的错流运动连续地扫过除尘器，并通过与除尘器的边界壁碰撞而经历自清洁作用，在除尘器的任一平行壁处，固体颗粒受到所施加的电场的作用。 或者，可以允许“携带灰尘”的固体颗粒离开除尘器以进行清洗，同时提供清洁固体颗粒的补充。 无论哪种情况，该过程在直流电场中都是连续的。
