Definitions

  • the present invention relates to an air-cooled condenser for the condensation of steam by means of air.
  • air-cooled condensers comprise pipe elements arranged parallel to one another—the so-called pipe bundles to which the steam to be condensed is supplied.
  • every two rows of such pipe bundles are usually arranged in such a way that they are inclined against one another at an acute angle in a gabled form.
  • they form a triangular contour, at the base of which a fan is provided for the supply of air to the pipe bundles.
  • the fan transports air, which is cool in comparison to the steam, to the pipe bundles in such a way that a heat exchange takes place, by which steam can condense on the inner edge of every pipe in the pipe bundle.
  • air-cooled condensers of such a triangular design and large cooling capacity have a large space requirement and also require a large installation height, which call for an expensive substructure.
  • the difficulty in air-cooled condensers is to achieve a uniform distribution of the steam into every pipe bundle.
  • the object underlying the invention is to create an air-cooled condenser, using which a large cooling capacity is economically feasible with a small space requirement and cost-effective design and with a uniform distribution of the steam into the pipe bundles.
  • an air-cooled condenser which comprises: a steam supply line, at least one upwardly directed pipe bundle, to which the steam to be condensed can be supplied, a condensate drain for the drainage of the condensed steam, a fan for the air transport through the pipe bundle, wherein the pipe bundle is arranged below the fan in a sidewall of the air-cooled condenser.
  • the lateral arrangement of the pipe bundles in the sidewalls firstly distinctly reduces the installation height of the air-cooled condenser.
  • the pipe bundle weights are no longer arranged at a large installation height, instead at a relatively low installation height, consequently enabling a lighter support structure of the entire air-cooled condenser, which is advantageous economically.
  • the arrangement of the pipe bundles in the sidewalls of the air-cooled condenser ensures a larger available area for the pipe bundles than in case of a triangular arrangement, in which only the sides of the triangle can be covered with pipe bundles. It is thus possible to achieve a larger cooling capacity of the air-cooled condenser with a low space requirement.
  • several pipe bundles are arranged in such a way that they form a jacket in the form of a polygon extending in the plumb line, wherein said jacket is closed such that it forms an enclosure on all sides. This is advantageous since the entire curved surface of the jacket above the bottom can be used for the pipe bundles.
  • the pipe bundle in a sidewall is inclined towards the plumb line in an angle range of ⁇ 30°.
  • the result is a funnel-shaped design of the air-cooled condenser, wherein the cross-sectional area at the lower end (bottom) is smaller than that at the upper end (top).
  • This permits the installation of a fan, which has a larger diameter than the base of the air-cooled condenser.
  • a fan of the largest size possible can be provided in case of a base of a minimum size, consequently achieving the maximum cooling capacity of the air-cooled condenser.
  • the required provisions for a stable design of the associated frame structure are still relatively few within this angle range of ⁇ 30°, thus making it possible to implement a frame structure still more cost-effectively.
  • the steam to be condensed is transportable using a riser duct to an upper distribution chamber and from there to at least one of the pipe bundles.
  • a riser duct to an upper distribution chamber and from there to at least one of the pipe bundles.
  • At least one upwardly directed residual steam pipe for the condensation of residual steam is provided from a condensate collection chamber below one of the pipe bundles.
  • the residual steam pipe serves for the separation of steam and inert gases.
  • a residual steam drain for the drainage of the insert gases including the non-condensed residual steam is provided at the upper end of the residual steam pipe.
  • the area outside the pipe bundles is hermetically sealed. This ensures that the air transported by the fan only flows through the pipe bundles.
  • the fan is provided with a diffuser. This enables an increase in the degree of efficiency of the fan.
  • FIG. 1 a front-view of a first embodiment of the inventive air-cooled condenser
  • FIG. 2 a horizontal cross-section of the first embodiment, shown in FIG. 1 , of the inventive air-condenser along the line 1 - 1 ;
  • FIG. 3 a perspective view of a second embodiment of the inventive air-cooled condenser.
  • FIG. 1 and FIG. 2 steam is supplied to the inventive air-cooled condenser 1 using a supply line 2 .
  • the steam thereby flows upwards by means of one or more riser ducts 3 and is distributed using distribution lines 4 into a respective distribution chamber 5 .
  • the distribution lines are indicated only schematically in FIG. 2 ; they can be further expanded or divided into several lines toward the distribution chamber 5 .
  • the distribution chambers 5 are arranged in the upper region of the air-cooled condenser. Below the distribution chambers 5 , pipe bundles are arranged, which are indicated schematically using the reference numeral 6 . 1, 2 or more pipe bundles can be provided to each sidewall 18 corresponding to the diameter of the fan. The hot steam in the pipe bundles condenses due to the heat exchange with the air flowing past the pipes.
  • the liquid condensed in the pipe bundles flows downwards along the pipe walls and is collected in a condensate collection chamber 7 , which is arranged below a pipe bundle. From the condensate collection chamber 7 , a condensate drain 20 flows outwards away from the air-cooled condenser.
  • the remaining residual steam and also the inert gases are guided upwards into a residual steam pipe 8 from the condensate collection chamber 7 .
  • the pipe bundle 6 thus represents a primary part, while the residual steam pipe 8 forms the secondary part.
  • the secondary part 8 can also be embodied as a pipe bundle.
  • the air stream 12 flows around the secondary part 8 just as the primary part 6 , thus enabling the condensation of one more portion of the residual steam in the secondary part 8 .
  • This portion flows back into the condensate collection chamber 7 while the non-condensed portion including the inert gases arrives at the upper end of the secondary part 8 into a residual steam chamber 9 .
  • residual steam and inert gases are discharged from the air-cooled condenser 1 using a residual steam line 10 , which is illustrated schematically as a dashed line in FIG. 1 .
  • a secondary part 8 can be provided in every pipe bundle of the air-cooled condenser 1 .
  • An air-cooled condenser thus also comprises several residual steam chambers 9 , from which residual steam is discharged outwards. It is expedient to couple the residual steam lines 10 to one another, which depart from the respective residual steam chambers 9 .
  • the pipe bundles are arranged in the sidewalls 18 .
  • Several sidewalls thereby form a jacket 13 in the form of a polygon extending in the plumb line and illustrated in the figures in the form of a hexagon, wherein said jacket is closed such that it forms an enclosure on all sides.
  • the previously described arrangement for a sidewall 18 is repeated in the sidewalls adjoining thereto, so as to achieve a symmetrical design of the air-cooled condenser 1 .
  • a uniform air passage through all the sidewalls can thus be achieved by means of the fan 11 .
  • the previously described polygon design of the jacket 13 can also be changed in such a way that the corners are present in a rounded form, thus achieving a round or almost circular geometry of the jacket 13 in the top view of the air-cooled condenser 1 . This can be advantageous for a uniform through-flow of the pipe bundles 6 .
  • the latter can be provided with a diffuser 19 .
  • FIG. 3 A second embodiment of the invention is illustrated in FIG. 3 . It schematically illustrates a hexagonal air-cooled condenser 1 , which however has no riser duct for the supply of steam, unlike the first embodiment.
  • the steam is directly supplied into the upper region of the air-cooled condenser, where it can arrive from the distribution chambers 5 to the pipe bundles (not illustrated here).
  • This can be advantageous if a steam supply line from an industrial unit connected upstream is already present in the upper region of an air-cooled condenser, as a result of which a diversion of the steam in the lower region of the air-cooled condenser 1 would only represent an unnecessary circuitous route.
