Plate column for heat and/or mass exchange

Abstract

Abstract A FRACTIONATING COLUMN HAVING A VERTICAL SHELL IN WHICH PAIRS OF VERTICAL STRIPS ARE FIXEDLY ATTACHED TO THE INTERNAL SURFACE OF THE SHELL AND EXTEND INWARDLY THEREOF. A PLURALITY OF VERTICAL PLATES IN THE SHELL AND CLAMPING DEVICES SECURING EACH PLATE AT THE ENDS THEREOF TO A RESPECTIVE PAIR OF STRIPS TO ENABLE VERTICAL ADJUSTMENT OF THE PLATE RELATIVE TO THE STRIPS. SUPPORT MEMBERS EXTENDING HORIZONTALLY ON THE PLATES AND SECURED THERETO. A PLURALITY OF SPACED SUPERPOSED TRAY IN THE SHELL AND EACH HAVING AN EDGE SECURED TO A RESPECTIVE SUPPORT MEMBER ON A PLATE WHEREBY THE TRAY IS SUPPORTED AT THE EDGE. THE VERTICAL PLATES EXTEND UPWARDLY OF THE TRAYS TO DEFINE WEIRS THEREFOR. THE VERTICAL PLATES ASSOCIATED WITH TWO SUCCESSIVE TRAYS ARE MUTUALLY OFFSET TO CAUSE LIQUID FLOWING OVER ONE WEIR TO ENCOUNTER THE NEXT LOWER TRAY. A BOLT ON EACH STRIP AT THE LOWER END THEREOF ENGAGING A CORRESPONDING TRAY AND A NUT ADJUSTABLY ENGAGED WITH THE BOLT FOR VERTICALLY ADJUSTING THE TRAY AT SUCH LOCATION RELATIVE TO THE SHELL INDEPENDENTLY OF THE ADJUSTMENT OF THE PLATE RELATIVE TO THE STRIPS. THE TRAYS ARE CONSTITUTED BY ALTERNATING FIRST AND SECOND SETS, EACH OF THE TRAYS OF THE FIRST SET ARE CONSTITUTED BY A PAIR OF SEMICIRCULAR COPLANAR HALF-TRAYS DEFINING A TRAY OF CIRCULAR FORM WITH THE CIRCULAR SIDE OF EACH HALF-TRAY EXTENDING TO THE SHELL. THE TRAYS OF THE SECOND SET ARE OF CIRCULAR FORM WITH RELIEVED PORTIONS ON OPPOSITE SIDES THEREOF. THE TRAYS OF THE SECOND SET EXTEND TO THE SHELL. THE PLATES ARE ARRANGED IN FIRST AND SECOND SETS. THE PLATES OF ONE SET ARE CONNECTED TO THE STRAIGHT SIDE OF EACH HALFTRAY AND EXTEND UPWARDLY THEREOF TO DEFINE THE WEIR FOR LIQUID FLOWING FROM THE HALF-TRAY DOWNWARDLY TO THE NEXT LOWER TRAY. THE PLATES OF THE OTHER SET ARE CONNECTED TO RESPECTIVE RELIEVED PORTIONS AND EXTEND UPWARDLY THEREOF TO DEFINE THE WEIR FOR LIQUID FLOWING FROM THE TRAYS OF THE SECOND SET DOWNWARDLY TO THE NEXT LOWER TRAYS. THE RELIEVED PORTIONS ARE PARALLEL TO THE PLATES OF THE ONE SET AND SPACED FROM THE SHELL A DISTANCE SUBSTANTIALLY EQUAL TO THE HORIZONTAL DISTANCE BETWEEN THE PLATES OF THE ONE SET WHICH ARE CONNECTED TO THE STRAIGHT SIDES OF COPLANAR HALF-TRAYS.
