Title: Improvements in the Electrical Separation of Suspended Particles from Gaseous Bodies.
Inventor: BURNS HERBERT ALEXANDER
IPC: B03C3/70
Filed: 1917-12-11
Abstract: 120,994. Burns, H. A. Dec. 11, 1917. Gases and vapours, treating electrically.-In apparatus for separating suspended particles from gases, the insulators and the ends of the conductive supports for the electrodes are placed in a chamber in which is maintained a gas pressure slightly higher than that in the dust-separating chamber, the insulators being remote from the opening between the chambers. Deposits on the insulators are thus prevented. The gas in the supplementary chamber may be air or, as in the treatment of pyrites-roaster or blast-furnace gases, a part of the purified gas delivered from the main chamber. When the impure gas contains particles of liquid, such as sulphuric acid, the air admitted to the subsidiary chamber may be heated by a steam-jacketed pipe or otherwise. In one construction, the bus-bars C supporting electrodes A pass through restricted orifices E into subsidiary chambers G containing supports F and insulators D. A slight suction is produced in the main chamber B either by natural draught or by a fan. Air inlets E' into the subsidiary chambers may be provided with adjustable shutters to regulate the quantity admitted. In another arrangement, a T-shaped support for the electrodes passes into an upper chamber containing an insulator at each end of the cross-arm.
