Abstract

L'invention concerne un support d'électrode pour un appareil précipitateur électrostatique permettant d'isoler aussi bien thermiquement qu'électriquement une ligne d'alimentation de ladite électrode, ce qui facilite à la fois son installation et sa maintenance. Ledit support comprend une base qui comprend une première extrémité latérale et une seconde extrémité latérale ; une partie cannelée située dans ou sur la base qui s'étend dans une direction longitudinale, ladite partie cannelée présentant au moins une première perforation ; une première protubérance positionnée au niveau de la première extrémité latérale et s'étendant dans la première direction transversale ; et une seconde protubérance positionnée au niveau de la seconde extrémité latérale et s'étendant la première direction transversale. L'invention concerne, en outre, un appareil précipitateur électrostatique qui comprend une source d'alimentation électrique, une première électrode connectée à la source d'alimentation électrique, un revêtement conducteur connecté à ladite source dans une polarité différence de la première électrode.
