Electrostatic Precipitation, a New Approach

提出了一种新的静电除尘方法，即利用带电的重固体颗粒悬浮在除尘器的平行壁之间，外加直流电场。这些颗粒比尘埃大102到104倍，由于对固体颗粒的撞击和静电吸引，它们将擦洗流动的尘埃气体。固体颗粒以相对于流动的污秽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动作，其中它们在所施加的电场的作用下在除尘器的任一平行壁处接收。或者，当提供清洁固体颗粒的补充剂时，可以允许携带粉尘的固体颗粒从除尘器中流出以进行洗涤。在任何一种情况下，这个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.
