  • a forced-draft cooling tower employs fans, [52] U.S. Cl 261/30, passages to receive fan-displaced air or gas, and packing sec- 261/79 A, 261/] 1 1, 261/DIG. 1 1 tions spaced about the tower axis so that positive swirling of [51] Int.

  • Conventional mechanical and natural draft towers typically employ grid decking or packing for draining and splashing water in such dispersed condition as to be cooled by air streams passing generally horizontally through the packing.
  • the packing decks normally extend continuously along the side or sides of such a tower in order to achieve direct inward flow through the packing of all air passing between the exterior and interior of the tower, this having been thought to be consistent with most economical tower construction and mode of operation. For example, it was thought that continuity of packing extent along the tower sides achieves maximum surface to area ratio, the surface referring to available wetted packing area presented to the entering air, and area referring to the ground area covered by the tower.
  • the invention is embodied in a tower construction that includes a series of fans spaced about and outwardly of the tower upright axis; plenum passages spaced about that axis and in the path of gas displacement by the fans; multiple packing sections spaced about the axis and located in the spaces between the passages for inlet exposure to the passages and outlet exposure to the tower interior; partitions to direct the flow of gas into the packing sections after gas reception in the passages so that the resultant flow swirls about the tower axis, and means to supply water (or other liquid) for dispersal within the sections to be cooled by the gas flow therethrough.
  • the passages act to equalize the fan-discharge flow to the packing sections, and also to isolate the fans from water splash near the packing, to prevent fan icing.
  • the structure enables housing of dampers, doors or similar devices for regulating airflow into the tower as required for cold-weather operation.
  • the tower shell may be of right circular cylindrical, hyperboloid of revolution or other geometrically regular form.
  • the tower construction may include certain upright partitions extending within the spaces between the packing sections to confine the air to enter the sections at the inlet sides and to flow laterally within the sections, such partitions for example extending diagonally between the outer extents of the outlet sides of the sections and the inner extents of the inlet sides of the sections to effect the spiral flow.
  • the fans are typically mounted at the tower periphery outwardly of the spaces between the packing sections to direct airflow toward the diagonal partitions.
  • the tower construction may include other partitions covering the outermost and innermost extents of the packed sections.
  • Additional objects and advantages of the invention include the provision of fan shrouds extending with gas-directing diffusing divergence from the fan peripheries toward adjacent packing sections; the provision of packing sections circularly arranged about a vertical central axis with section elongation generally radially; the provision of vanes in the passages or spaces between the packing sections and angled to guide the fan-displaced gas flow into the packing sections; the provision for inlet flow of air to the plenum passages in bypassing relation to the fans when the latter are shut down, to enable natural-draft mode of tower operation; the provision of watersupply means including a water basin overlying the section and spaces therebetween, the basin having dispersal openings located only over the sections; the provision of means including piping having water outlets direct-ed to discharge water into the basin to flow therealong and over the sections and spaces therebetween; and the provision of a basin underlying such spaces to receive water splashing into the spaces from the packing sections.

  • the illustrated water-cooling tower is of mechanical-draft type, wherein air is displaced horizontally into the lower interior of the tower and rises in the stack ill of vertical cylindrical shape and defining a central axis 10a.
  • the stack has modular panel construction, as shown, and is circular in horizontal planes as is the annular lower portion 12 of the tower. While airflow to cool dispersed water is described, it will be understood that gas flow to cool liquid is comprehended within the scope of the invention.
  • the tower includes a plurality of water-receiving packing sections having inlet and outlet sides laterally separated in a direction generally lengthwise or circumferentially of the tower horizontal periphery. As seen in FIG.
  • the sections 13 are typically rectangular in plan view with inlet and outlet sides 13a and 13b separated in the circumferential direction. Further, the sections 13 are circularly arranged about the vertical central axis llia of the tower, with spacing therebetween indicated at M for reception of air between the sections. Air displaced into these spaces, or plenum passages 14a then turns to flow through the sections 13 between sides 13a and 13b, and is subsequently received in spaces 14b for exit flow to the tower interior I00. Arrows I5 designate the general flow path. As is clear from FIG. 2, the
  • the flow through the sections 13 has a substantial component 15a concentric with the (circumferential) direction of the tower horizontal periphery, and the resultant flow into the tower interior and about axis 10a produces a swirl effect.
  • the latter upward spiral course of the positive flow induces enhanced mixing of the moisture-laden air or gas, so as to decrease the density thereof in order to increase the tendency of the air to rise in the tower.
  • the airflow may typically approach a turbulent-flow state, permitting increased air-water contact with consequent raising of the wet bulb temperature of the exit air, thereby improving the water-cooling performance.
  • Certain partitions or control baffles extend within the plenum passages 14 to direct the air to enter the sections 13 at their inlet sides, to flow laterally therein as described.
  • vertical partitions 16 may be provided to extend diagonally between the outer extents 17 of the outlet sides 13b of the sections 13 and the inner extents 18 of the inlet sides 13a of the sections.
  • other vertical partitions 19 and 20 are provided to cover the outermost and innermost extents of the sections 13. Such partitions may extend throughout the vertical heights of the sections 13 to block airflow through those inner and outer extents or ends.
  • the like sections 13 are radially horizontally elongated and the overall radial dimension of the section multiplied by the number of such sections substantially exceeds the boundary dimension (as for example circumference of tower lower portion 12) defined by the outer extents of the sections. Accordingly, a substantially higher than normal ratio of surface to area" is achieved, these terms having been previously defined.
  • fans 30 are spaced in circular series about axis a and radially outwardly therefrom, the fans also being spaced outwardly of the plenum passages 14a and oriented to positively displace air into those spaces when the fans are rotated by motor 31. Accordingly, the fans are kept well away from the sections 13 to prevent icing of the blades due to water splash in cold weather. Also, flow of air into the sections is equalized by the plenum passages.
  • the fans have blades 32 and may be housed in such relation to passages 14a that air may freely flow past the fans and into those passages when the fans are shut down, providing an auxiliary natural-draft mode of tower operation as may be desirable or effective under certain weather condition.
  • the spaces 33 between the blades may pass such airflow, or alternatively the fan housing may provide for such bypass flow.
  • the fan motors 31 may be supported on stands 34 having legs 34a and a crosspiece 34b as shown.
  • Housing of the fans 30 may be effected by means of shrouds 35 having venturi shape, forming throats 36 receiving the fans and diffuser sections 37 to expand the flow to the full vertical flow area of the plenum chambers.
  • the shrouds may, for this purpose be vertically elongated as seen in FIG. 5, and extend with divergence to tops and bottoms 38 and 39 of the passage opening, and to the vertical sides 40 and 41 thereof.
  • FIG. 7 illustrates the use of additional flow guides such as vanes 44 in passages 14a, and angled to direct the fandischarge flow uniformly into the packing sections.
  • Dampers may be used to regulate the inlet airflow, as during coldweather operations. See, for example, dampers 75 movable in shroud 35 in FIG. 8, as by pivoting at 76.
  • FIGS. 14 means is provided to supply liquid, as for example water, for distribution within the sections in order to be cooled by airflow through the latter, the water typically falling in dispersed drops which splash and film on the decking surfaces or slats.
  • liquid as for example water
  • FIG. 4 indicating a closely packed section 13 of such fill as inclined downwardly and in the direction airflow through the fill, water particles tending to fall in the packing with corresponding angularity from vertical.
  • Tower structure supporting the fill includes columns 55, ties 56 and bracing 57.
  • An upright drift eliminator 58 is spaced close to the outlet side 13b of the packing for eliminating drift particle form the exit air stream.
  • the water supply means illustrated in the drawings includes a hot water basin 60 overlying the packing sections 13 and the spaces 14a and 14b therebetween.
  • hot water may be pumped from a concrete supply conduit 62 upwardly within a riser 62 to a flume or piping 63 extending transversely and and inwardly across the basin 60.
  • the latter has multiple outlets 64, individually valve controlled at 65, directed to discharge water into the basin for open-channel flow therealong in the length direction of the basin.
  • the basin has intermittent groups 66 of distribution openings 67 located lengthwise thereof, for dispersing water into and onto the decking or packing sections 13; also the basin over the spaces 14 between sections 13 is free of such holes so that water does not drain from the basin into the interiors of those air spaces.
  • any water splashing from the packing into the spaces 14 falls into the collection basin 69 at the bottom of the tower, and no louvers are needed to intercept such splash since spaces 14 are within the tower.
