Definitions

  • the invention relates to a plant for the condensation of steam with the features of claim 1.
  • Air-cooled condensers are used for the direct condensation of turbine exhaust. They can be considered as a special form of use of air-cooled heat exchangers. Air-cooled heat exchangers are used to cool fluids using ambient air in various processes in the chemical, petrochemical and power generation industries.
  • the heat exchangers essentially consist of heat exchanger tubes, which are provided on the outside with ribs due to the poor thermal conductivity of the air to improve the heat transfer.
  • the heat transfer to the cooling medium air using heat exchangers by heat conduction and convection is often referred to as dry cooling.
  • the heat exchanger tubes of air-cooled heat exchangers are combined into so-called bundles by welding them into flat, perforated, thick-walled metal sheets, which are also called tube sheets. These bundles are referred to as finned tube bundles or tube bundles.
  • the cooling medium air is conveyed through the heat exchanger bundles with the help of suction or blowing fans.
  • a common construction is the so-called roof construction method.
  • fans are in an oppressive arrangement below roof-shaped heat exchanger bundles.
  • the roof-shaped arranged heat exchanger bundles with the fans are supported by a support structure, the fans are supported by a fan bridge.
  • the adaptation of air-cooled condensation plants to the Abdampfmenge or turbine size and the operating and environmental conditions (air temperature) can be done in principle on the change of the heat exchanger surface and / or on the change of the cooling air flow.
  • fans in axial design are used in all air-cooled heat exchangers for industrial applications, since they are suitable to deliver the required large volume flows at low pressure differences.
  • a geometric basic pattern which is also referred to as a module, is produced depending on the design. If the modules or cells are arranged one behind the other (series connection), so-called multi-cell, single-row systems are created. Due to the air supply of Below, cells or modules in roof construction can also be produced by connecting several roof rows of air-cooled condensers in almost any size in parallel.
  • the main advantage of the roof construction method is the possibility of using the parallel and series connection of the individual cells to produce very large systems.
  • the fans arranged below the heat exchanger bundles must be provided with protective grids in the roof construction method for protection against falling parts or in the event of damage to the fan.
  • the fan race which is arranged to achieve defined flow conditions to the fan or fan, the air inlet height.
  • the support structure on which rest the heat exchanger bundles must be increased accordingly.
  • Another disadvantage may be due to recirculation of the heated cooling air. Due to the low hot air velocities in the roof construction of the capacitors, a so-called wind wall must be installed around the outer heat exchanger elements, which consist of an additional support structure with wind wall panels.
  • Heat exchanger bundles in V-arrangement with overhead fans can be built in a lower height, but are in heat exchanger bundles that are not self-supporting, very complex support structures required ( DE 103 23 791 A1 ). For this reason, heat exchangers in V-construction are mostly used only in the area of process coolers with horizontally arranged heat exchangers (water recooler, air-conditioning technology). There, the sizes are significantly or significantly smaller, whereby the support structure for the V-arrangement is economically feasible. The fans are also smaller and lighter. For larger systems, however, the support structure is always more complex and was previously considered uneconomical.
  • the DE 10 2007 012 539 B4 discloses to store at bottom fans and roof-shaped heat exchanger elements above a frame-like fan field on a reduced number of supports in order to reduce the steel construction cost. Below each fan field, at least one support is provided in the form of a column running vertically to the fan fields, with obliquely extending head struts, which extend to the corners of a fan field, adjoining the fan field and the column above the column. The fans themselves are mounted on or on the fan fields.
  • the plant according to the invention for the condensation of steam comprises tube bundles which are connected with their upper ends to steam distribution lines and with their lower ends are connected to condensate collector.
  • the tube bundles are thus flowed through from top to bottom by steam.
  • the tube bundles are arranged in a V-shape, so that the steam distribution lines of a pair of tube bundles are at a greater distance from each other than the condensate collector of the pair of tube bundles, which are arranged in the region of a lower vertex of the V-shaped arrangement.
  • At least one fan is arranged in the region between the steam distribution lines.
  • the basic geometrical pattern of tube bundles arranged in V-shape, the fans arranged above the pair of tube bundles, the associated steam distribution lines in the upper area and the condensate collectors in the lower area will also be referred to below as a cell or module. It is a unit in which the heat flow transmitted by the bundles and the cooling air volume flow absorbing this heat are in equilibrium.
  • the fan is carried by a central pillar extending from the fan to the crown. That is, the central pillar penetrates the triangular in cross-section interior, which widens from bottom to top in the direction of the fan.
  • the tube bundles themselves are mounted on a support bracket which extends in the longitudinal direction of the apex and is connected to the central support pillar.
  • the central pillar therefore not only takes the load of the fan, but on the support brackets, the load of the tube bundles and the support brackets themselves.
  • the tube bundles are self-supporting. This means that the tube bundles do not require an additional support structure to support the tube bundles against deflection, for example. It is sufficient if the tube bundles in the region of its lower end, that is, in the region of the apex have a support and are also fixed in the region of their upper ends.
  • Mutually adjacent tube bundles may, for example, be connected to one another via a common steam distribution line.
  • the fan is a relatively heavy component, wherein a fan in the context of the invention, both the drive unit and the associated gear unit and the fan blades themselves are understood.
  • This fan unit contributes significantly to the total weight of the condensation plant.
  • the weight of the fan is not transmitted via a fan console or fan platform, which in turn is mounted on the tube bundles, but the weight is introduced directly into the buttress.
  • the pillar itself is the central, load-bearing component that additionally absorbs the weight of the self-supporting tube bundles via the support brackets. Added to this is the weight of the condensate collector and the steam distribution lines, which are arranged on the upper side or underside of the tube bundle.
  • the entire weight of such a cell or such a module via a single buttress in the footprint, especially the ground, are derived. It is not necessary to provide a variety of foundations or supports per cell. It should be noted that usually several such modules are used in series or parallel connection. The cells or modules can therefore support each other laterally. Larger systems also get their stability through the plurality of modules or cells and the majority of central pillars. Preferably, units of at least four modules are mounted in a carafe arrangement.
  • the weight of the fan or the fan assembly can be derived particularly effective when the central pillar extends vertically below the fan to the support bracket.
  • the invention does not exclude that the central buttress for reasons of air flow or for reasons of design or design does not extend downwards centrally from the fan, but the central solution is considered to be the most appropriate solution.
  • the central support pillar preferably also has a lower portion, which is continued below the support bracket to the footprint of the system.
  • the abutment therefore has two sections which are loaded to different degrees.
  • the upper portion within the triangular prismatic area defined by the tube bundles carries the fan or fan assembly.
  • the lower Section of the central buttress also adds the weight of the tube bundles and the supply and discharge lines. So that the entire arrangement remains in equilibrium, the arrangement is preferably arranged symmetrically with regard to the central supporting pillar. This means that the support brackets are preferably the same length.
  • modules are stored on the crossbeams.
  • the cross members are preferably carried by the lower portions of the central pillars.
  • the cross members are dimensioned and arranged so that fewer pillars are required with a protruding up to the footprint lower length section are available as a total support pillars.
  • the connection between the cross members and the footprint may be via the pillars of only every other row of modules. If the buttresses which protrude to the footprint are not the pillars of the marginal ranks, then e.g. five rows of modules are stored on two buttresses below the second and fourth rows. With a number of n rows, therefore, n-3 pillars are sufficient for support on the installation surface.
  • cross member supports which are not congruent with the lower lengths of the central columns.
  • cross member supports may be additionally or alternatively provided to lower portions of the central columns.
  • the number of cross member supports is smaller than the number of central columns of the modules.
  • the adjacent tube bundles can also be referred to as a roof-shaped arrangement or roof row.
  • the respective outer tube bundles are without outside support by another tube bundle.
  • You can be connected by struts with the respective adjacent inner tube bundles.
  • Tensile and compressive forces are derived by means of struts over the adjacent cell.
  • the outer tube bundles are connected to their own steam distribution lines.
  • the cross sections of the outer rows of the steam distribution lines may be smaller than the cross sections of the inner steam distribution lines.
  • the sealing and support of a fan race surrounding the fan is provided by means of a secondary support structure.
  • the secondary support structure carries and includes in particular closed walls. These form, so to speak, the end or gable end of the V-shaped arrangement of tube bundles.
  • the secondary support structure comprises in particular a supporting structure of individual struts. This secondary support structure is self-supporting. It in turn rests on or on the primary support structure and there on the support brackets.
  • the primary supporting structure also includes the central supporting pillar. For the secondary support structure of the support pillar is in particular a centering in the horizontal direction, so that the fan race is arranged concentrically to the fan.
  • This secondary support structure does not carry the load of the tube bundles, but serves to seal the triangular prism-shaped interior and to provide a floor on which the fan race is mounted.
  • the secondary support structure may be a truss structure in which struts have the supporting function and trim elements disposed thereon have a sealing function. But it is also possible that the secondary support structure has self-supporting, flat support elements, for example made of fiber-reinforced plastics, in particular of glass fiber reinforced plastics.
  • the fan race can be made of the same material as the support elements. It can be part of a fan cover that is the same as the upper end the cell forms.
  • the dreickeckförmigen side walls may have maintenance openings.
  • Support pillars of a single vertex that is, a single row
  • adjacent pillars of different rows of V-shaped arrangements to run towards each other and are also stored on a common foundation. It can therefore groups of two pillars or even groups of four pillars are combined and stored on a common foundation.
  • the cost of storage of the entire capacitor assembly can be reduced under certain conditions.
  • foundations or supports are not arranged vertically underneath the fans, horizontal forces arise that have to be absorbed.
  • adjacent pillars and / or tube bundles and / or support brackets can be connected to each other via struts. The exact arrangement results from the size and orientation of the horizontal forces and ultimately also from the design and location of the abutments and foundations.
  • the support bracket is a cantilever cantilevered to the buttress, comparable to a branch on a trunk.
  • the support bracket itself is not additionally supported compared to the footprint.
  • the forces that rest on the support brackets are taken up exclusively via the central pillar and discharged downwards.
  • support means in particular in the form of ropes or rods, can be provided which are fastened in particular to the distal ends of the support bracket and which extend from the upper end of the support pillar to the lower support pillar extend.
  • the pillars and / or the support brackets may be at least partially formed by trusses.
  • the buttress can be configured differently due to its load profile in its upper portion than in its lower portion.
  • the buttress may be at least partially tubular. It can be a concrete support tube or a steel tube. Tubular abutments have the advantage that the abutment itself can form a channel to direct cooling air from the bottom up to a drive unit of the fan. For pillars in the form of truss girders may be installed in the truss structure channels to direct the cooling air from the bottom up to a drive unit of the fan in the same way. In addition, a fan may be provided to suck or push the cooling air through the channel in the buttress.
  • Such a blower is only required if the suction pressure of the fan is insufficient.
  • a transmission and a drive for the fan below the support brackets that is, is arranged below the supports of the tube bundle within or on the central buttress and is connected via a very long drive shaft to the fan.
  • the central support pillar allows direct access to the maintenance of the fan group.
  • Tubular or pylon-like abutments can be provided with a corresponding climbing aid.
  • a walk-in cleaning stage In the area of the vertex, a walk-in cleaning stage can be mounted, so that the individual tube bundles are easily accessible and can be maintained.
  • the underlying structure of the invention and the combination of V-shaped heat exchanger arranged in several rows make it possible to produce systems for the condensation of steam, with sucking arrangement of the fan, in any required size particularly economical.
  • the lower height also causes the lengths of the steam-carrying pipelines to be reduced. Since very large cable cross-sections are used here, this difference is significant.
  • the arrangement of the central pillar further reduces the cost of materials for the primary support structure and fan support.
  • FIG. 1 shows a plant 1 for the condensation of steam.
  • the system 1 is shown purely schematically and is intended to illustrate only the constructive principle.
  • the plant 1 comprises tube bundles 2, which are connected with their upper ends 3 to steam distribution lines 4. With their lower ends 5, the pipes 2 are each connected to condensate collector 6.
