Definitions

  • a cooling tower especially for condensing of vaporous media and for cooling liquid media, which is provided with air inlet means in the lower zone of the cooling tower mantle and is also provided with air discharge means in the upper portion of the cooling tower mantle.
  • the cooling tower comprises a plurality of heat exchanging components arranged radially over the cross section of the cooling tower above the air inlet means to form circular rings of components. The height of the rings decreases in the radial direction from the outer periphery of the cooling to the center thereof, and the heat exchanging components are respectively in the form of roof-type structures having a gas impermeable guide wall for the cooling air and a heat exchange wall to be contacted by the cooling air.
  • the heat exchange elements or components of such cooling towers consist of fin equipped or plain tubes through which flows the medium to be cooled, which medium conveys the heat to be discharged to the cooling air flowing around the outer surfaces of the tubes.
  • This air enters radially through the air inlet apertures, and, after being heated up on the heat exchange surfaces, is with ventilator cooling towers discharged through the diffuser mouth, or with towers cooled by natural draft is through the upper outlet opening of the cooling tower mantle discharged into the environment.
  • Another problem underlying the present invention consists in equalising the differing supplies of cooling air for the heat exchange components distributed over the surface of the cooling tower in such a way as to obtain a possibly uniform cooling action over the crosssection of the tower.
  • the invention adopts a fundamentally different way according to which the different flow profiles in the cooling tower are equalised over the radius of the cooling tower by adapting the specific heat exchange surface to the flow profile of the cooling air.
  • the specific exchange surface is defined as the ratio between the heat exchange surface and the inflow surface, the latter being deemed to be the horizontal cross section of the cooling tower on a level with the heat exchange components.
  • a surface of the roof-shaped design is designed as air guiding wall inasmuch as the upper edge-of each element located on a circular ring is connected to the foot of the respective adjacent element by a non-air-permeable partition, whereas the other surface forms the exchange surface.
  • the heat exchange wall comprises plain tubes and tubes with fins through which a heat exchange medium may pass. It is also preferred that the guide wall of each component forms the upper edge of the heat exchange wall to the base of the neighboring component in the same ring.
  • the invention furthermore provides that the height of the heat exchange components decreases continuously on a gradient from the outer edge of the cooling tower towards the center. According to a preferred embodiment of the invention, the height of the heat exchange components decreases in steps from the edge to the middle of the cooling tower, the group of heat exchange components resting on the same circular ring always having the same height, which height decreases from group to group from the outer area to the inner area.
  • the heat exchange surface can for all practical purposes under optimal conditions be adapted to the existing flow profile of the cooling air, which results in equal heat exchange conditions throughout the whole cross section of the cooling tower.
  • the width and length of the individual components are optional and are derived from the heat exchange conditions and the data of the medium to be cooled. Accordingly, the number of groups of components arranged over the radius of the cooling tower, and their dimensions, as well as the number of components arranged within a group, can vary.
  • the heat exchange surface of the roof-type structure which surface is provided with heat exchanging elements
  • the air guiding walls may consist of sheet metal, asbestos, cement, or plastics material, or the like.
  • the specific heat exchange surface rises over the length of a component with constant width or height in inverse proportion to the square of the cooling tower radius.
  • a preferred form of the invention makes provision for the specific heat exchange surface to be adapted continuously or step by step to the flow profile of the cooling air, or to be superimposed thereon. This can be done by reducing the height of the components, in the case of a central arrangement, towards the middle of the cooling tower, or else with an inclined arrangement of the components, the angle of incidence of the components with the inflow surface is reduced continuously or in steps, with a simultaneous reduction in the width of the component.
  • the arrangement of the components over the radius of the cooling tower is, as a rule, horizontal if liquid media are to be cooled. Merely for the sake of better emptying, the components may be given a slight slant. A similar arrangement can be provided in the case of condensation processes for the better discharge of the condensate.
  • the air guiding walls arranged between the upper edge of a component and the base of a neighboring component act at the same time as wind interception walls. Additional wind breaks, such as are arranged in known structures to avoid the blowing through of individual components, below or between the individual components, may not therefore be necessary.
  • the invention provides that the heat exchange surfaces and the partitions may be arranged on alternate sides over the radius of the cooling tower, while the heat ex change surfaces and the partitions are on opposite sides in the individual groups.
  • the individual groups can either be operated separately or else be interconnected. Accordingly, the medium to be cooled may be supplied either through an external circular pipe, or through several circular pipes over the radius of the cooling tower. The medium being cooled, or the condensate, is then discharged through circular pipes which are arranged either in the middle of the cooling tower only, or approximately on the inner radius of circles in which the groups of components are located.
  • a further advantage is obtained due to the fact that the whole of the cross section of the cooling tower is utilized in an optimum manner; only in the middle of the cooling tower is there a dead space which can be utilized for the arrangement of pipes and as a transport lock.
  • the entire crosssectional surface of the tower may be covered with the heat exchange components. It is, however, also possible to design the cooling tower in the well-known manner as a combined wet-dry cooling tower in order to derive the advantages arising therefrom, namely the prevention of vapor emerging from wet cooling towers and the improvement of the steep characteristic of dry cooling towers, and to reduce the additional water requirement of wet cooling towers by the basic load being taken over by the dry cooling part and the peak load by the wet cooling part.
  • the cooling tower may be so constructed that components for wet cooling, such as trickle units, are distributed over the cross section of the cooling tower between one or more rows of heat exchange components extending in the radial direction, so that sector-shaped portions of dry cooling components and wet cooling components follow one another alternately.
  • components for wet cooling such as trickle units
  • FIGS. 1 and la show a partly cut-away side view through the lower part of a natural draft circular cooling tower in the form of a dry cooling tower only.
  • FIGS. 2 and 2a respectively represent two diagrammatic representations seen from above the heat exchange components, which are shown arranged in a semi-cross-section of the cooling tower.
  • FIG. 3 is an isometric representation of heat exchange components arranged one after the other in a radial direction.
  • FIG. 4 shows an enlarged isometric representation of a heat exchange component with an inclined arrangement.
  • FIG. 5 shows four heat exchange components placed one behind the other in a radial direction, while being arranged vertically.
  • FIG. 6 is an isometric illustration similar to FIG. 4, of a heat exchange component in a vertical arrangement.
  • FIG. 7 is a top view of the exchange components and trickle devices shown arranged in semi-cross section in a combined wet-dry cooling tower.
  • FIG. 8 is a cross section taken along the line VIII- -VIII of FIG. 7.
  • the circular cooling tower of FIG. 1 comprises a shell or mantle l, which has passage means la in the lower zone to form air inlets, through which air enters radially in the direction of the arrows 2.
  • the heat exchange components 3 Above the intake orifices 1a there are arranged the heat exchange components 3, which occupy almost the whole cross section of the cooling tower except for a central free area, so that the cooling tower acts solely as a dry cooling tower.
  • the air entering radially flows, as denoted by the arrows 4, through the individual components 3 and emerges through an upper discharge orifice from the cooling tower.
  • FIG. 2 is a top view of the heat exchange elements, which are arranged in the cooling tower; these heat exchange components are combined to form the groups I, II, III and IV which are located along'circles. Struts 5 act as the supporting means for the heat exchange elements.
  • the height of the components 3 decreases from group to group in steps and is constant within each group, while in FIG. la a form of embodiment of the invention is represented in which the height of the components of a group, and from group to group, decreases continuously from outside to inside.
  • FIG. 3 shows several groups of heat exchange components 3, one behind the other in a radial direction, those of each group being placed side by side.
  • the illustrated components or heat exchange elements form a sector-shaped portion of the whole installation.
  • the heat exchange components are accommodated in a roof-type structure, one surface 6 of which contains heat exchange tubes 7, which run horizontally in the illustrated example while the other surface 8 is an airtight partition serving as air guiding wall.
  • the roof-type structure is open at the bottom, so that air entering in the direction of the arrows 9 is able to pass through the individual heat exchange components.
  • the front and rear ends of the roof-type structure are likewise closed by sealing walls in order to compel the cooling air to pass through the heat exchange components.
  • the exchange surface 6 of the roof-type structure is arranged obliquely, while the respective air guiding wall 8 is vertical, or approximately vertical.
  • the air guiding wall 8 runs from the upper edge of the rooftype structure to the base of the adjoining component and thus compensates for the widening of the cooling tower towards the outer edge, produced by the radial arrangement in the circular base area.
  • the heat exchange surface is oblique and the partition mainly vertical
  • the exchange surface 6 is vertical or substantially vertical
  • the air guide wall 8 is arranged obliquely.
  • the height of the exchange components varies in steps from group to group, the components of group 1 having the least height and the components of the group on the outer edge of the cooling tower having the greatest height.
  • FIG. I It is apparent from FIG. I that the components are arranged substantially horizontally. For condensation processes and for cooling liquids they are given a slight gradient towards the center of the cooling tower, in order to improve the drainage conditions for the condensate, or to make complete emptying feasible.
  • FIGS. 7 and 8 show a so-called wet-dry cooling tower also of circular design, which not only contains the roof-type exchange components 3 for dry heat exchange, the medium to be cooled flowing through the exchange tubes and being cooled by the cooling air flowing past, but also is fitted with a wet cooling part as well, which contains trickle plates 10.
  • the water being cooled trickles down said plates 10 from top to bottom, while it is cooled by the rising cooling air.
  • rows of exchange components 3 and parallel trickle plates 10 suspended one behind the other are with the pertaining water distributing system and drip collectors arranged alternately side by side, so that seetor-shaped wet and dry lanes or ducts are created which fill up the cross section of the tower.
  • the exchange components 3 are formed and arranged in the same way as has been explained in conjunction with FIGS. 1 to 6.
  • a cooling tower especially for condensing vaporous media and for cooling liquid media, which includes: a mantle having a lower section provided with intake passage means for admitting a gaseous cooling medium into the interior of said mantle, said mantle also having an upper section provided with discharge means for discharging the heated up gaseous cooling medium after it has performed its cooling action, and a plurality of heat-exchanging elements distributed over the cross section of said cooling tower and located in radial arrangement at a level higher than the level of said intake passages and considerably closer to the latter than to said discharge means, said heat exchanging elements including roof-shaped bodies arranged along concentric circles and including tubes adapted to be connected to and to convey the medium to be cooled, the height of said heat exchanging elements decreasing in radial direction from the outer periphery of said cooling tower to the central axis thereof, said roof-shaped bodies having a gas-impermeable guide w all forming one surface and having a heat exchange wall of said tubes forming the other surface.
  • a cooling tower according to claim 1 in which the height of the heat exchanging elements decreases in a continuous manner on a gradient from the outer periphery of the cooling tower towards the center.
  • a cooling tower according to claim I in which the height of the heat exchanging elements decreases in steps from the outer periphery of the cooling tower to the center thereof, the group of heat exchanging elements arranged along one and the same circle having the same height.
