Abstract

Le précipitateur électrostatique selon l'invention inclut un logement, un circuit haute tension, des plaques électroconductrices (21, 22, 23, 24, 25, 31, 32, 33, 34) et une électrode d'ionisation haute tension (1). Les plaques électroconductrices sont disposées en parallèle à l'intérieur du logement et chaque groupe de plaques, qui sont disposées de façon alternée et côté à côte tout en étant espacées les unes des autres, est connecté électriquement. Le circuit haute tension est connecté électriquement à l'électrode d'ionisation haute tension (1) et les plaques électroconductrices sont divisées en un premier groupe de plaques de terre et en un second groupe de plaques de charge. Le premier groupe de plaques de terre et le second groupe de plaques de charge sont disposés de façon alternée. Deux plaques de terre disposées sur les côtés extérieurs sont pourvues de parties allongées (211, 251) et l'électrode d'ionisation haute tension (5) est disposée au centre des plaques et en parallèle à celles-ci à l'intérieur de l'espace défini par les parties allongées (4), ce qui permet de créer un espace d'ionisation correspondant audit espace en cas de fonctionnement, les bords avant des plaques de charge faisant saillie dans l'espace d'ionisation. Sur la base du principe de l'adsorption de charge, les plaques de charge peuvent être chargées. Il est par conséquent inutile d'appliquer 40 kV supplémentaires aux plaques de charge, ce qui permet de parvenir à une simplification de la configuration et à une réduction du coût du fait qu'un circuit haute tension puisse être supprimé. De plus, le précipitateur électrostatique est bien plus sûr car il n'est pas nécessaire d'appliquer une haute tension aux plaques électroconductrices.
