Abstract

1,196,171. Gas-scrubber. D. ROMELL. 12 April, 1967, No. 16795/67. Heading BlR. A gas-scrubber comprises an enclosure with a duct through which gas to be scrubbed is passed, means to spray at least two jets of liquid and at least one first electrically conducting body and at least one second electrically conducting body spaced from the first electrically conducting body and electrically insulated therefrom, the arrangement being such that a first one of the jets of liquid passes by a first electrically conducting body at a distance therefrom and thereafter at least a part impinges on a second electrically conducting body and a second one of the jets of liquid passes by a second electrically conducting at a distance therefrom and thereafter at least a part impinges on a first electrically conducting body, the jets and first and second electrically conducting bodies constituting a Kelvin liquid-influencing machine and at least one jet after passing at least one electrically conducting body traversing the duct 1 scrubbing gas passing therethrough. As shown in Fig. 1 first and second electrically conducting bodies each comprise interconnected pairs of electrodes 12 and 15 and 13 and 14 respectively, the electrodes 14 and 15 each having an orificed plate 16 mounted thereon so that washing liquid from nozzles 9 and 10 after passing through electrodes 12 and 13 respectively impinges in part upon the electrodes 14 and 15. Liquid issuing from electrodes 14 and 15 passes into a duct 2 through which gas to be scrubbed is passing through openings 21 and 22. In operation each pair of electrodes may be given initial opposite charges or one pair of electrodes may be given a charge. As shown the jet of liquid from nozzle 9 is given a charge by an electrete 25. One or more wires such as 26 may 'be arranged in the duct 2 adjacent the gas inlet 3 and connected electrically to the electrode 12, the word(s) serving as a corma discharge electrode. In modifications the electrically conducting bodies may be arranged in the duct traversed by the gas to be scrubbed or be in part constituted by a section of the duct insulated from the enclosure.
