Electrostatic Precipitation, a New Approach

提出了一种利用带静电的重固体颗粒在直流外加电场的作用下悬浮在平行的除尘器壁上的新方法。这些颗粒比灰尘大102到104倍，由于固体颗粒的撞击和静电吸引，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横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使其经历自清洁作用，在除尘器的平行壁上任一处接受外加电场的作用。或者，可以允许“携带灰尘”的固体颗粒通过除尘器进行洗涤，同时提供清洁固体颗粒的组成。在任何一种情况下，该过程在直流电场中都是连续的。

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.
