Abstract 1,005,632. Electrostatic precipitators. METALLGESELLSCHAFT A.G. June 16, 1964 [June 19, 1963], No. 24979/64. Heading B2J. The corona discharge field of an electrostatic precipitator comprises grate-like component elements 4 which are formed of round star or spiked wires and/or iron strips 1 welded into square or oblong frames 2 and connected together in electrically conducting manner on the unit construction principle. As shown in Figs. 1 and 8, each frame 2 carries two rows of discharge electrodes 1 in staggered formation and is connected to the frame adjacent to it by either rivets or screws 5 so as to make the frames readily exchangeable. Fig. 7 shows various constructions of collecting electrodes each having dust-collecting pockets in staggered formation to suit the arrangement of discharge electrodes. Fig. 6 shows various constructions of collecting electrodes which call for single rows of discharge electrodes. The discharge electrodes 1 in each frame may be further supported by a strip secured across the middle of the frame. If desired, the grate-like component elements may be formed of wires and/or strips welded at the top and bottom to flat iron bars which are secured in a precipitator framework comprising a rectangular frame with cross-bracing struts.
IN AN ELECTROSTATIC DUCT SEPARATOR HAVING SPACED ROWS OF VERTICALLY DISPOSED LONGITUDINALLY EXTENDING PLATE-LIKE PERCIPITATING ELECTRODES FORMING A LONGITUDINALLY EXTENDING GAS PASSAGEWAY AND A PLURALITY OF VERTICALLY DISPOSED WIRE-LIKE EMITTING ELECTRODES POSITIONED IN SAID GAS PASSAGEWAY SUBSTANTIALLY MIDWAY BETWEEN SAID PRECIPITATING ELECTRODES, THE IMPROVEMENT COMPRISING SUPPORT MEANS LOCATED IN SAID PASSAGEWAY FOR SUPPORTING SAID EMITTING ELECTRODES COMPRISING A PLURALITY OF VERTICALLY ARRANGED OPEN-ENDED RECTANGULAR FRAME COMPOOSED OF FLAT IRON STRIPS, EACH SAID FRAME HAVING CONNECTED FLAT TOP, BOTTOM AND SIDE WALL PORTIONS AND HAVING OPEN ENDS FACING SAID PRECIPITATING ELECTRODES, SAID EMITTING ELECTRODES BEING FIXEDLY AND ELECTRICALLY CONDUCTIVELY SECURED TO THE PERIPHERAL EDGE OF SAID FLAT TOP AND BOTTOM WALL PORTIONS, SAID FRAME BEING STACKE WITH SAID FLAT WALL PORTIONS IN SURFACE CONTACT WITH EACH OTHER, AND MEANS SECURING AND ELECTRICALLY CONNECTING SAID FRAMES TO EACH OTHER.
