Definitions
- the invention relates to a method for constructing a condensation plant according to the features in the preamble of patent claim 1.
- the individual tube bundles of an A-type air condenser are preassembled on a roof-shaped preassembly rack.
- the pre-assembly has exactly the inclination, which should have the individual tube bundle in the installed position.
- the tube bundles to be connected to each other are lifted by means of a crane on the pre-assembly, so that they face each other in the ridge area. So far, it was so that tapped holes were provided in the end-side bottom plates of the tube bundles, so that pre-assembly angle could be screwed between the two tube bundles.
- the tube bundles connected in this way are then transported into the installation position.
- angle iron which extends in the longitudinal direction of the ridge-side steam distribution line to be welded later.
- the angle iron points with its corner area upwards. His thighs are welded via a fillet weld on both long sides with the bottom plates of the tube bundles.
- Angle irons with their longitudinal edges do not rest exactly on the bottom plates, which in turn makes welding difficult or even impossible.
- the previous procedure therefore required time-consuming reworking under certain circumstances. It has initially gone over to use slightly larger sized angle iron, so as not to collide with the pre-assembly angles and to prevent any delays in assembly. The cost of materials is higher due to the larger angle iron.
- an angle iron must also be provided in this area, which is not intended to prevent the escape of steam, but rather serves to direct the flow of cooling air through the tube bundles and to allow no leaks in the ridge area.
- Another disadvantage is that the previously used pre-assembly and the angle iron must be painted after installation for corrosion protection with paint, the interior is extremely poorly accessible below the angle. Although this area is not subject to corrosion by precipitation, since it is constantly subjected to cooling air and therefore can not trap rainwater, but the angle iron can enforce the humidity, especially if such condensation plants have been built for power plants in tropical regions.
- the object of the invention is to improve the pre-assembly of the tube bundles to be connected to a tube bundle delta with regard to the material as well as the time expenditure.
- the tube bundles are placed with their, the heat exchanger tubes holding floor plates in cushions on a first strut of Vormontagegestell so that the facing longitudinal sides of the floor panels are welded together by means of a Trentaht before the thus preassembled, roof-shaped Rohrbündeldelta lifted from the pre-assembly and in the installed position is spent. The final welding takes place in the installation position.
- the root seam will be welded only in those areas where there are no supports. On the one hand, this has practical reasons, since the supports should not be damaged by the welding process. On the other hand, it is not necessary to lay the root seam over the entire width of a tube bundle, since even shorter weld seam sections already have a sufficient load capacity. Of course, it is expedient to pull the root seam already during the pre-assembly on the pre-assembly as long as possible, so as much preliminary work as possible can be done for at least one final covering seam.
- the upper longitudinal edges of the mutually facing longitudinal sides of the floor panels at an angle be chamfered twice, so that an upper chamfer with a larger chamfer angle and a lower chamfer with a smaller chamfer angle, wherein the smaller chamfer angle is selected such that the lower of the chamfers of the floor panels run parallel to each other.
- Such a preparation of welds aims at, for example, being able to weld together over the total sheet thickness at an angle of 30 ° to one another.
- the opening angle of the V-seam between the two floor panels may therefore be preferably 60 °, i. It is an upper chamfer angle of 60 ° at each longitudinal edge appropriate, since the floor panels themselves are each inclined by 30 ° relative to the horizontal.
- the inventive method unfolds its advantages both in tube bundles, which are connected dephlegmatorisch as well as tube bundles, which are connected in a condensed manner. In any case, eliminates the relatively heavy angle iron.
- the invention also makes subsequent application of anticorrosive paint to the floor panels welded together much easier, since no undercut cavities are formed.
- the inventive type of pre-assembly of the tube bundle is also significantly time-saving compared to the previous approach. Calculations have shown that through the modified pre-assembly so far not only 10 tube bundle deltas per day could be set up, but 12 to 14 tube bundle deltas. The time to set up the Rohrbündeldeltas is of concern, because a crane is required to set up the Rohrbündeldeltas. The cost of cranes are regularly very high.

- FIG. 2 shows a heat exchanger delta in the installation position
- Fig. 4 shows an enlarged view of the longitudinal sides of the floor panels of
- Fig. 5 is a sectional view through the ridge region of a
- FIG. 1 shows a sectional view of a roof-shaped preassembly frame 1, on which two tube bundles 2, 3 rest, in order to be connected to one another in their ridge area.
- Figure 5 illustrates how the connection of the tube bundle 2, 3 so far took place.
- the two floor panels 5, 6 are screwed together.
- the preassembled heat exchanger delta was moved to the installed position. There, the illustrated angle iron 9 was slipped over the pre-assembly 8 and welded via V-seams with the bottom plates 5, 6.
- the pre-assembly angle 8 and the angle iron 9 are completely eliminated. Rather, the floor panels 5, 6 of the tube bundle 2, 3 placed on spaced supports 10 (see Fig. 3), which are fixed to a first strut 11 of the pre-assembly 1.
- the support surfaces 10 have on their upper side bearing surfaces for the floor panels 5, 6.
- the bearing surfaces form a kind of V-shaped groove, so that the floor panels 5, 6 touch with their facing longitudinal sides 12, 13 in the deepest of the groove and there over a Rooted seam can be welded together.
- the root seam is not shown in detail and is not welded in the area of the supports 10, but rather between two supports so as not to damage them.
- FIG 4 shows an enlarged view of the ridge area of a heat exchanger delta 14 constructed according to the invention, already with welded steam distribution line 4 and in enlargement the area of the mutually facing longitudinal sides 12, 13 of the floor panels 5, 6.
- the floor panels 5, 6 in each case by 30 ° inclined to the horizontal. This results in that the end faces are at an angle of 60 ° to each other, as shown in Figure 4 at the bottom.
- the floor panels 5, 6 were chamfered twice.
- the upper chamfers are dimensioned so that in the installation position an angle of 30 ° with respect to the vertical or an opening angle of 60 ° between the two floor panels 5, 6 is formed.
- the chamfer angle of the inclination of the floor panels 5, 6 relative to the horizontal ie in this embodiment corresponds to 30 °.
- the floor panels 5, 6 touch each other flat in a 2 mm wide area. This region of the surface contact is melted over the first welded root seam, so that a solid bond between the two bottom plates 5,6 and thus between the tube bundles 2, 3 is formed. Above the root seam, the already mentioned cover seams are welded in the installation position.
