Definitions

  • the invention relates to a wet cooling tower in a block arrangement, each block having a plurality of cells.
  • a wet cooling tower as it is known, for example from DE 196 51 848 Cl, has within a cooling tower shell substantially horizontally disposed sosstechniksverteil effeten, wherein the liquid is supplied via a riser shaft to the distribution lines. Cooling off warm liquid, especially water, is trickled from the distribution lines from top to bottom to Rieseleinbauriin. The liquid droplets come into contact with cooling air flowing in from outside / which is sucked in via air inlet grille at the bottom of the cooling tower. The air is sucked against the waterfall by the trickle body built upwards. If the air flow has a lower temperature than the water to be cooled, heat is removed from the water and cools down. The warm moist air is sucked upwards by a fan arranged on the cooling tower and discharged to the environment. The cooled water falls down and collects in pools that are located below the distribution lines. It can be supplied to the heat source again.
  • the amount of heat dissipated by a cooling tower depends on the state of the incoming cooling air. It has been found that a cooling tower occasionally sucks in the warm humid air or swaths it gives off. Such recirculation is undesirable because the performance of the cooling tower is significantly reduced. Further, it has been observed that adjacent cooling towers, which are arranged in a block, for example, in series, suck each other's own swaths. This effect, referred to as interference, also leads to a reduction in performance of a cooling tower or of a cooling tower constructed from a plurality of blocks.
  • the invention is therefore an object of the invention to provide a cooling tower of the type mentioned above, in which the recirculation and the interference are reduced and thus a higher cooling capacity of the cooling tower is achieved.
  • Such a block arrangement thus has more than 2 cells both in the block longitudinal direction and in the block transverse direction.
  • This preferably comprises a block of 3 x 3 cells or 4 x 4 cells or 4 x 3 cells or 5 x 3 cells, etc.
  • the invention further relates to a cooling tower with inner walls of concrete, wherein preferably the walls are arranged in the main axes of the block assembly.
  • This makes it possible to build a large proportion of the cooling tower of glass fiber reinforced plastic (GRP) according to the invention, the concrete walls serve as a "backbone" for the GRP structure and measure to stabilize the cooling tower.
  • GRP glass fiber reinforced plastic
  • the concrete walls extend from the liquid collection basin of the cooling tower to the cooling tower roof.
  • GRP structure By means of the GRP structure, a lightweight construction is generally achieved. Due to the concrete walls, which are preferably arranged in the main axes of the cooling tower, it is also possible to dispense with cross struts and diagonal struts of GRP, while still achieving a reliable statics. Due to the no longer required GRP struts, a more cost-effective construction is achieved.
  • concrete walls Preferably arranged in the main axes concrete walls serve as a support structure for other walls of glass fiber reinforced plastic or wood.
  • Another advantage of such a composite construction of GRP and concrete is that the concrete walls can act as fire walls. If the concrete walls are arranged in the main axes of the cooling tower, clearly separate fire protection zones are created. In a block arrangement with 4 x 4 cells, this results in 4 fire protection zones, each including 4 cells.
  • the concrete walls are provided on adeturmmantel addition with an extension. This is advantageous because on the one hand further protection against flashover by fire is given.
  • a wind deflecting wall is created by the extension of the walls, which absorbs a larger proportion of the incoming air to the cooling tower and thus improves the air supply to the cooling tower.
  • the walls of concrete over the cooling tower roof also provided with an extension.
  • the fire zone is prevented from simply overlapping the adjacent cells of a cooling tower.
  • this measure channels the hot air discharged from the fans.
  • the cooling tower according to the invention has according to a further preferred embodiment bevelled or rounded corner areas, in particular of the cooling tower shell on.
  • an air flow around the cooling tower is improved so that less air fractions are directed towards the cooling tower base, which can additionally reduce the risk of recirculation.
  • the water to be cooled is transported from a riser shaft main distribution pipes and adjoining secondary distribution pipes to at least one cell of the cooling tower, wherein the secondary distribution pipes of a cell are arranged at right angles to secondary distribution pipes of a cell adjacent thereto.
  • the secondary distribution pipes of a cell are arranged parallel to secondary distribution pipes of a cell adjacent thereto. In the latter arrangement, only one main distribution pipe is required. If the secondary distribution pipes are arranged at right angles to each other, a main distribution pipe is required in both main axes. This solution is suitable for a symmetrical design of the cooling tower, if, for example, concrete walls are provided in the main axes and can be laid in these main distribution pipes.
  • a common riser shaft for feeding water into the cells is provided in the cooling tower for at least six cells.
  • the pumping power for the water to be cooled increases only insignificantly in a central riser shaft, so that there still remains an economic advantage compared to the construction of a cooling tower with a single riser shaft for each cell.
  • a feed for individual cells or for cells arranged in pairs is feasible from the common riser shaft.
  • At least one riser shaft for supplying water to the cells is provided in the concrete walls.
  • the cooling tower stabilization can be combined with the supply of the water to be cooled, so that there is less additional space requirement.
  • Fig. 1 is a plan view of a cooling tower in block construction according to a first embodiment with 16 cells;
  • FIG. 2 shows a horizontal cross section through the cooling tower of the first embodiment according to FIG.
  • Fig. 3 is a side view of the cooling tower of FIG. 1;
  • FIG. 4 and 5 show a second and a third horizontal cross section through the cooling tower according to FIG. 1;
  • Fig. 6 is a plan view of a cooling tower of a second embodiment with 16 cells.

It has four cells 4 in a longitudinal direction, marked with the arrow 100, and four cells 4 in a transverse direction perpendicular thereto, marked with the arrow 200, so that a total of 16 cells form a square block 3.
  • the cells 4 of the block 3 are surrounded by a cooling tower jacket 5.
  • thedeturmmantel 5 at the outer corners of the block 3 each have chamfered or rounded corners 6.
  • the symmetrical structure of the block 3 is crossed by main axes 7 and 9, which are arranged perpendicular to each other. They have at the outer edge in each case an extension 8, 10, which protrudes laterally beyond thedeturmmantel 5.
  • the extensions 8, 10 extend to the outer edge of the base 2 of the cooling tower 1.
  • Each cell 4 is provided with an associated fan 12 which is placed over the air outlet 11 of each cell 4.
  • a central riser shaft for the supply of cooling water is provided for every 2 ⁇ 2 cells.
  • the risers 13, 14, 15 and 16 thus provide an arrangement of four times 2 x 2 cells with the water to be cooled.
  • the main axes 7, 9 are designed as concrete walls 50, 60 and serve to achieve an improvement in the stability of a cooling tower in fiberglass construction. They support, as a "backbone", the predominant CFRP structure 17, see Figures 2 and 3, wherein savings can be made in cross braces and diagonal braces made of FRP through the concrete walls
  • the extensions 8, 10 of the concrete walls 50, 60 improve the supply
  • the chilled corners 6 at the outer corners of the cooling tower improve the airflow around the cooling tower, which measures reduce the risk of recirculation of the exhaust air discharged from the fans ,
  • the GRP structure of the cooling tower is apparent from Figures 2 and 3. It extends from the base of the cooling tower to the cooling tower roof and is "mesh-like." The transverse and diagonal struts are not shown for stiffening the structure, and the air outlet 11 delivers warm air drawn in from the fans 12 from the bottom to the top The air outlet takes place at the same height for each cell, so that a concentrated and bundled exhaust air flow can be achieved.
