Abstract
1449310 Electrostatic precipitators T R W Inc 28 Aug 1974 [5 Aug 1974] 37560/74 Heading B2J Undesirable fluid components and particulate matter are removed from a gas stream 14 by a method comprising the steps of:-(a) causing the gas stream to flow between conducting elements 11, 12 and past a spray tube 27 provided with nozzles 33; (b) forcing a liquid 16, e.g. water which may contain a chemical agent such as sodium hydroxide to react with an undesirable gas such as sulphur dioxide, through the spray tube to generate a stable jet at a hydrostatic pressure insufficient to break up the jet into droplets; (c) applying a steady electric potential between the jet and the elements 11, 12, thereby to break up the jet by the resulting electrostatic field into individual droplets having a diameter between approximately 60 microns and 250 microns, each droplet having a high surface charge density: (d) causing the charged droplets to flow towards the element 11, 12 at an angle with respect to the direction of flow of the gas stream, whereby the droplets will collide with individual particles or undesirable fluids to remove them; and (e) eventually causing the droplets to move toward the elements, due to the electrostatic field, where they collide and collect. A plurality of spray tubes 27 may be provided (Figs. 5 and 6, not shown), and the elements 11, 12 may be sprayed to flush collected particulate matter therefrom (Fig. 8, not shown).
