Electrostatic apparatus for removal of dust particles from a gas stream

Claim 1

AN APPARATUS FOR REMOVING PARTICLES ENTRAINED IN A GAS STREAM FROM THE STREAM COMPRISING FIRST AND SECOND ELECTRODES SPACED APART WITH RESPECT TO EACH OTHER, ELECTRICAL POTENTIAL ESTABLISHING MEANS CONSTRUCTED AND ARRANGED FOR ESTABLISHING AN ELECTRICAL POTENTIAL GRADIENT BETWEEN SAID ELECTRODES SUFFICIENT TO EFFECT A CORONA DISCHARGE THEREBETWEEN, SAID ELECTRICAL POTENTIAL ESTABLISHING MEANS COMPRISING A FIRST SOURCE OF ELECTRICAL POTENTIAL AND A SECOND SOURCE OF ELECTRICAL POTENTIAL OF THE SAME SIGN AND LESSER VALUE THAN SAID FIRST SOURCE BUT ABOVE GROUND POTENTIAL, SAID FIRST ELECTRODE BEING ELECTRICALLY CONNECTED TO SAID FIRST SOURCE OF ELECTRICAL POTENTAL, SAID SECOND ELECTRODE BEING ELECTRICALLY CONNECTED TO SAID SECOND SOURCE OF ELECTRICAL POTENTIAL, AN ELECTRICALLY CONDUCTIVE ENCLOSURE, AN ELECTRICALLY CONDUCTIVE LIQUID CONTAINED WITHIN SAID ENCLOSURE, MEANS CONSTRUCTED AND ARRANGED FOR APPLYING A GROUND POTENTIAL TO SAID LIQUID, AN ELECTRICALLY NONCONDUCTIVE ENCLOSURE HAVING A PLURALITY OF OPENINGS THROUGH THE BASE THEREOF, THE BASE OF SAID ELECTRICALLY NONCONDUCTIVE ENCLOSURE TOGETHER WITH THE OPENINGS THERETHROUGH BEING SUBMERGED IN SAID LIQUID, SAID ELECTRICALLY NONCONDUCTIVE ENCLOSURE BEING DISPOSED ABOUT SAID ELECTRODES AND THE SPACE THEREBETWEEN TO EFFECT ELECTRICAL INSULATION BETWEEN SAID ELECTRODES AND SAID LIQUID, AND GAS MOVING MEANS CONSTRUCTED AND ARRANGED FOR FLOWING SAID GAS THROUGH THE CORONA DISCHARGE BETWEEN SAID ELECTRODES AND THEN THROUGH THE OPENINGS IN THE BASE OF SAID ELECTRICALLY NONCONDUCTIVE ENCLOSURE INTO SAID LIQUID, SAID GAS MOVING MEANS CONSTRUCTED AND ARRANGED TO PRODUCE SUFFICIENT PRESSURE IN SAID FLOWING GAS STREAM AND SAID OPENINGS BEING OF A SUFFICIENT SIZE TO ADMIT SAID GAS STREAM INTO THE LIQUID IN SAID ELECTRICALLY CONDUCTIVE ENCLOSURE AS BUBBLES BUT TO PREVENT ESCAPE OF SAID LIQUID FROM SAID ELECTRICALLY CONDUCTIVE ENCLOSURE INTO THE ELECTRICALLY NON-CONDUCTIVE ENCLOSURE THROUGH SAID OPENINGS.

Claim 2

AN APPARATUS FOR REMOVING PARTICLES ENTRAINED IN A GAS STREAM FROM THE STREAM COMPRISING FIRST AND SECOND ELECTRODES SPACED APART WITH RESPECT TO EACH OTHER, ELECTRICAL POTENTIAL ESTABLISHING MEANS CONSTRUCTED AND ARRANGED FOR ESTABLISHING AN ELECTRICAL POTENTIAL GRADIENT BETWEEN SAID ELECTRODES SUFFICIENT TO EFFECT A CORONA DISCHARGE THEREBETWEEN, SAID ELECTRICAL POTENTIAL ESTABLISHING MEANS COMPRISING A FIRST SOURCE OF ELECTRICAL POTENTIAL AND A SECOND SOURCE OF ELECTRICAL POTENTIAL OF THE SAME SIGN AND LESSER VALUE THAN SAID FIRST SOURCE BUT ABOVE GROUND POTENTIAL, SAID FIRST ELECTRODE BEING ELECTRICALLY CONNECTED TO SAID FIRST SOURCE OF ELECTRICAL POTENTAL, SAID SECOND ELECTRODE BEING ELECTRICALLY CONNECTED TO SAID SECOND SOURCE OF ELECTRICAL POTENTIAL, AN ELECTRICALLY CONDUCTIVE ENCLOSURE, AN ELECTRICALLY CONDUCTIVE LIQUID CONTAINED WITHIN SAID ENCLOSURE, MEANS CONSTRUCTED AND ARRANGED FOR APPLYING A GROUND POTENTIAL TO SAID LIQUID, AN ELECTRICALLY NONCONDUCTIVE ENCLOSURE HAVING A PLURALITY OF OPENINGS THROUGH THE BASE THEREOF, THE BASE OF SAID ELECTRICALLY NONCONDUCTIVE ENCLOSURE TOGETHER WITH THE OPENINGS THERETHROUGH BEING SUBMERGED IN SAID LIQUID, SAID ELECTRICALLY NONCONDUCTIVE ENCLOSURE BEING DISPOSED ABOUT SAID ELECTRODES AND THE SPACE THEREBETWEEN TO EFFECT ELECTRICAL INSULATION BETWEEN SAID ELECTRODES AND SAID LIQUID, AND GAS MOVING MEANS CONSTRUCTED AND ARRANGED FOR FLOWING SAID GAS THROUGH THE CORONA DISCHARGE BETWEEN SAID ELECTRODES AND THEN THROUGH THE OPENINGS IN THE BASE OF SAID ELECTRICALLY NONCONDUCTIVE ENCLOSURE INTO SAID LIQUID, SAID GAS MOVING MEANS CONSTRUCTED AND ARRANGED TO PRODUCE SUFFICIENT PRESSURE IN SAID FLOWING GAS STREAM AND SAID OPENINGS BEING OF A SUFFICIENT SIZE TO ADMIT SAID GAS STREAM INTO THE LIQUID IN SAID ELECTRICALLY CONDUCTIVE ENCLOSURE AS BUBBLES BUT TO PREVENT ESCAPE OF SAID LIQUID FROM SAID ELECTRICALLY CONDUCTIVE ENCLOSURE INTO THE ELECTRICALLY NON-CONDUCTIVE ENCLOSURE THROUGH SAID OPENINGS.
