Abstract
Abstract EXHAUST GASES CONTAINING ENTRAINED PARTICLES ARE LED CENTRIFUGALLY, AND DOWNWARDLY IN A CYLINDRICAL VESSEL PROVIDED WITH A LIQUID SPRAY. PASSING OUT OF THE LOWER END OF THE FIRST VESSEL, THE GASES TRAVEL UP THE ANNULUS BETWEEN THAT VESSEL AND A LARGER CYLINDRICAL VESSEL. THE ANNULUS IS PROVIDED WITH FRUSTO-CONICAL BAFFLES WET BY LIQUID SPRAYS AND SERVE TO CHANGE DIRECTION OF GAS FLOW AND TO THROW LIQUID WITH ENTRAINED PARTICLES TOWARD THE INNER AND OUTER WALLS OF THE ANNULUS WHERE FALLING FILMS RESULT. THE LIQUID FOR THE UPPER FEW BAFFLES IS PREFERABLY WATER AND FOR THE LOWER BAFFLES, THIN LIQUOR. TWO ADJACENT INTERMEDIATE BAFFLES EXTEND TO THE RESPECTIVE SIDEWALLS FOR DRAINING THE FRESH WATER WASHING ZONE.
