Definitions

  • the invention relates to an air condenser for the condensation of steam by means of air.
  • the invention is therefore an object of the invention to provide an air condenser, with which a small size and cost-effective design, a large cooling capacity with uniform distribution of the steam in the tube bundle is economically achievable.
  • an air condenser which comprises: a steam supply line, at least one upwardly directed tube bundle, which is supplied to be condensed steam, a condensate drainage for the discharge of condensed steam, a fan for air transport through the tube bundle, said the tube bundle is arranged below the fan in a side wall of the air condenser.
  • the overall height of the air condenser is significantly reduced.
  • the tube bundle weights are no longer in great height, but arranged in a relatively low height, so that a lighter support structure of the entire air condenser is possible, which is economically advantageous.
  • a larger available area for tube bundles than in a triangular arrangement in which only the triangular legs are covered with tube bundles.
  • a larger cooling capacity of the air condenser can be achieved with a small footprint.
  • a plurality of tube bundles are arranged so that they form a mutually enclosing closed jacket in the form of a vertically extending polygon. This is advantageous, since thus the entire lateral surface above the bottom can be used for tube bundles.
  • the tube bundle is inclined in a side wall in an angular range of ⁇ 30 ° to the vertical. If the inclination has a negative value, for example -30 °, a funnel-shaped structure of the air condenser results, the cross-sectional area at the lower end (bottom) being smaller than at the upper end (roof).
  • a maximum fan can be provided so that a maximum cooling capacity of the air condenser is achieved.
  • a riser to an upper distribution chamber and from there to at least one of the tube bundle transportable.
  • At least one upwardly directed residual steam pipe for condensing residual steam is provided by a condensate collecting chamber below one of the tube bundles.
  • the residual steam pipe serves to separate steam and inert gases.
  • a residual steam discharge for discharging the inert gases including the non-condensed residual steam is provided at the upper end of the residual steam pipe.
  • the surface outside the tube bundle is sealed airtight. This ensures that the air transported by the fan flows only through the tube bundles.
  • the fan is provided with a diffuser. This allows an increase in the efficiency of the fan.
  • Fig. 1 and Fig. 2 steam is supplied to the air condenser 1 according to the invention via a feed line 2.
  • the steam flows upwards by means of one or more risers 3 and is distributed via distribution lines 4 into a respective distribution chamber 5.
  • distribution lines are in Fig. 2 indicated only schematically; they can fanned out further to the distribution chamber 5 or split into several lines.
  • the distribution chambers 5 are arranged in the upper region of the air condenser. Below the distribution chambers 5 are tube bundles, which are shown schematically by the reference numeral 6. Depending side wall 18 can be provided according to the diameter of the fan 1, 2 or more tube bundles. The hot steam in the tube bundles condenses through the heat exchange with the air flowing past the tubes.
  • the condensed in the tube bundles fluid runs down along the tube walls and collects in a condensate collection chamber 7, which is arranged below a tube bundle. From the condensate collection chamber 7 leads a condensate discharge 20 to the outside of the air condenser.
  • the remaining residual steam and the inert gases are fed into a residual steam pipe 8 from the condensate collection chamber 7 upwards.
  • the tube bundle 6 thus represents a primary part, while the residual steam pipe 8 forms the secondary part.
  • the secondary part 8 can also be designed as a tube bundle.
  • the secondary part 8 is like the primary part 6 flows around the air flow 12, so that it is possible that still condenses a portion of the residual steam in the secondary part 8. This portion flows back into the condensate collection chamber 7, while the non-condensed fraction including the inert gases at the upper end of the secondary part 8 passes into a residual vapor chamber 9. From there, residual steam and inert gases via a residual steam line 10, which is shown schematically as a dashed line in Fig. 1 is shown, discharged from the air condenser 1.
  • a secondary part 8 may be provided in each tube bundle of the air condenser 1.
  • an air condenser also has a plurality of residual steam chambers 9, from which residual steam is discharged to the outside. It is expedient to couple the residual steam lines 10, which depart from the respective residual steam chambers 9, to one another.
  • the tube bundles are arranged in the side walls 18.
  • a plurality of side walls thereby form a closed jacket 13 surrounding on all sides in the form of a polygon extending in the vertical, represented in the figures in the form of a hexagon.
  • the arrangement previously described for a side wall 18 is repeated in the side walls adjacent thereto, so that a symmetrical structure of the air capacitor 1 is achieved.
  • By means of the fan 11 can thus be achieved by all the side walls uniform air passage.
  • the above-described polygon construction of the shell 13 can also be varied such that the corners are rounded, so that in the plan view of the air capacitor 1, a round or nearly circular geometry of the shell 13 is achieved. This can be advantageous for a uniform flow through the tube bundles 6.
  • a diffuser 19 In order to increase the suction effect of the fan 11, it may be provided with a diffuser 19.
  • a second embodiment of the invention is shown. It shows schematically a hexagonal air condenser 1, which, in contrast to the first embodiment, however, has no riser for the supply of steam.
  • the steam is here directly in the upper area of the air condenser supplied where it can get from the distribution chambers 5 to the (not shown here) tube bundles. This can be advantageous if a steam supply line from an upstream industrial plant is already present in the upper region of an air condenser, so that a diversion of the steam into the lower region of the air condenser 1 would represent only an unnecessary detour.
