The Electrofiltration of Particulates from Gases

  • Edmund C. Potter

Abstract

It is part of our more profound recognition of the world about us that matter and energy cannot be satisfyingly described without reference to electric charges and their movements. Such a statement is justified by the dominant roles of electricity and of electronics in our everyday lives, adding up to a wealth of man-made experiences that take precedence over natural manifestations of electrical phenomena. In this class stands electrostatic attraction, which is exploited on the large scale for the efficient removal of particulate nonconductors from suspension in gases. The electrostatic precipitation of dusts, mists, smoke, and fume is an established process for cleaning gases permitted to enter the atmosphere, and electrostatic precipitators (or electrofilters) play an important part in stopping excessive air pollution from combustion equipment and by various industrial processes including cement manufacture and ore smelting. This chapter describes the principles of electrostatic precipitation and examines the manner of their application in practice.
