Abstract 1,074,840. Cooling towers. FLUOR CORPORATION Ltd. Nov. 25, 1964 [Aug. 28, 1964], No. 48005/64. Heading F4K. A cross-flow cooling tower 10 comprises an annular ring of packing 14 surrounding an interior region 13 above which are spaced, about a vertical axis through the tower, a series of fans 16 which provide communication between the interior region and an air exhaust stack 18, the fans drawing cooling air horizontally through the packing and out vertically through the stack via Venturi-shaped fan rings 53. Water distributing means comprise a decking 33 supported on beams 34, the decking having outlet nozzles 36 spaced above the packing ring. Water is supplied to the decking from an annular flume 37 through control gates 39 in the flume wall 40. A cylindrical baffle 15 situated about the vertical axis inside region 13 turns the air flow upwards towards fans 16. Aligned radial partitions 38 and 44 are mounted in vertical planes above the decking 33 and within region 13 respectively, forming decking portions 33a and convergent subregions 13a which direct the incoming air to each fan. Water from the packing rings drop into an annular basin 20 and is collected from a trough 21. The region 13 is covered by a deck 45 which supports the fan driving means 52 and has access provided to it by a tunnel 48 and a staircase 49 inside the baffle 15.
IN A CROSSFLOW TYPE COOLING TOWER HAVING A CENTRAL VERTICAL AXIS, MEANS FORMING A CHAMBER HAVING AN INTERIOR REGION LOCATED ABOUT SAID AXIS, UPRIGHT INTERIOR PARTITIONS CIRCULARLY SPACED APART IN SAID REGION AND EXTENDING INWARDLY TOWARD SAID AXIS, WATER SUPPLY MEANS, PACKING EXTENDING GENERALLY ANNULARLY AND CONTINUOUSLY ABOUT SAID INTERIOR REGION FOR RECEIVING WATER DROPPING DOWNWARDLY FROM SAID WATER SUPPLY MEANS TO BE CONTACTED BY COOLING AIR PASSING ACROSS SAID PACKING GENERALLY INWARDLY TOWARD SAID INTERIOR REGION, AN AIR EXHAUST STACK EXTENDING GENERALLY CIRCULARLY ABOUT SAID AXIS AND PROJECTING ABOVE THE TOP LEVEL OF SAID CHAMBER FOR RECEIVING AIR FROM SAID INTERIOR REGION, A SERIES OF FANS HAVING GENERALLY VERTICAL AXES OF ROTATION SPACED CIRCULARLY ABOUT SAID AXIS TO LOCATE THE FANS IN OPEN VERTICAL COMMUNICATION WITH SAID INTERIOR REGION AND STACK FOR DISPLACING AIR TO FLOW FROM SAID INTERIOR REGION UPWARDLY IN SAID STACK SO THAT THE AIR VELOCITY INCREASES AS THE AIR PASSES INWARDLY ACROSS SAID PACKING AND INTO SAID INTERIOR REGION, A VERTICALLY PROJECTING GENERALLY CYLINDRICAL AIR BAFFLE EXTENDING ABOUT SAID AXIS INWARDLY OF SAID INTERIOR REGIN TO HELP EFFECT AN UPWARD TURNING OF THE AIR FLOW IN SAID INTERIOR REGION AND TOWARD THE UNDERSIDES OF THE FANS, AND A DECK SUPPORTING THE FANS OUTWARDLY OF A VERTICAL PROJECTION OF SAID BAFFLE, AND INWARDLY OF A VERTICAL PROJECTION OF SAID STACK, THE DECK HAVING OPENINGS TO PASS AIR DISPLACED BY THE FANS BUT OTHERWISE SUBSTANTIALLY COVERING SAID INTERIOR REGION, EACH OPENING OVERLYING A SUB-REGION FORMED BETWEEN A PAIR OF INTERIOR PARTITIONS.
