Abstract

An electrostatic gas cleaner can be provided to remove particulate matter, including particles of fluid, from gas exhausted from other apparatus. Such an electrostatic gas cleaner consists of wall means forming a large open flow path for gas to be cleaned. An electrode carrier is removably supported within said wall means and includes a plurality of projecting and electrically non-conductive portions to position and support the electrode carrier within the wall means and to position and support an electrode with respect to the wall means. The electrode carried by the electrode carrier creates an electrostatic field within the wall means. A gas to be cleaned is uniformly distributed and directed through the large open flow path formed by the wall means by a closure means at one end of the wall means. The electrostatic field from the electrode to the wall means charges and deposits particles carried by said gas on said wall means before they pass from the gas cleaner. Preferably, the wall means is in the form of a grounded metallic cylinder which is heated by electrical heating means. The electrode carrier preferably includes a metallic tube and a plurality of radially extending and …
