...A type of dust collection method in which dust particles are charged by passing an airflow containing dust between electrodes where corona discharge is occurring, and the particles are moved to the dust collection electrode by the electric field to attach and separate the dust particles in the gas. Electrical dust collection is also commonly called Cottrell precipitation, named after the inventor of this device, American Frederick Gardner Cottrell (1877-1948). In this method, the electrical resistance of the dust naturally affects the dust collection efficiency. *Some of the terminology that refers to "Cottrell precipitation" is listed below.

…集塵方法の一種で,粉塵を含む気流をコロナ放電が発生している電極間を通して粒子に電荷を与え,その粒子が電界によって集塵電極へと移動する現象を利用して気体中の粉塵を付着分離する方法。電気集塵は,この装置の発明者であるアメリカのコットレルFrederick Gardner Cottrell(1877‐1948)の名を付して,一般にコットレル集塵Cottrell precipitationとも呼ばれている。この方法では当然粉塵の電気抵抗が集塵効率に影響を及ぼす。… ※「Cottrell precipitation」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
