Electrogasdynamic precipitator with catalytic reaction
Abstract
Abstract METHODS AND APPARATUS FOR RIDDING UNDESIRED GASEOUS COMPONENTS AND ENTRAINED PARTICLES FROM AN EXHAUST FLOW, IN WHICH GASEOUS FLOW RECEIVED FROM AN ELECTROGASDYNAMIC PARTICLE-REMOVING PRECIPITATOR IS CONTACTED WITH A CATALYST TO BRING ABOUT A REACTION BETWEEN THE GASEOUS COMPONENTS. THE PRECIPITATOR INCLUDES CORONA DISCHARGE ELECTRODES FOR CREATING A DISCHARGE TO CHARGE THE PARTICLES ELECTRICALLY, AN INTERMEDIATE DIELECTRIC CONDUIT AND A LARGER CONDUCTIVE POROUS TUBULAR COLLECTOR FOR TRAPPING THE CHARGED PARTICLES PRECIPITATED BY SPACE CHARGE FIELD OR BY AN APPLIED ELECTRIC FIELD BETWEEN THE TUBULAR COLLECTOR ELECTRODE AND A CENTRAL PASSIVE ELECTRODE. THEREAFTER THE GAS FLOW IS CONTACTED WITH A CONDUCTIVE CATALYST ASSEMBLY IN THE FORM OF A COILED RIBBON TO REACT THE GASEOUS COMPONENTS.
