Definitions
- the invention relates to a heating plate package for tangential or radial installation in Heating surface supports of regenerative heat exchangers with trapezoidal segmented cells with fixed or rotating storage masses, that from a large number of alternately arranged, different curls, there is between profile sheets leaving flow channels, such as by GB-A-1439674.
- the regenerative heat exchanger can be used for both air preheating (Luvos) as well as for gas preheating (Gavos).
- an air preheater it is used in power plant and industrial combustion plants to preheat the combustion air and as a gas preheater in exhaust gas cleaning, for example at catalytic reactors, for preheating or for gas scrubbing Reheating used.
- the heat exchange between the outflowing hot Gas and the air supplied to it in counterflow is either by a rotating heating surface support or - with a fixed heating surface support - by arranged on both sides of the storage masses, around a common axis continuously rotating hoods reached.
- the heating surfaces or storage masses of such regenerative heat exchangers exist from two differently profiled, for example 0.5 to 1.3 mm thick, optionally coated or enamelled steel sheets, the corresponding bundled the cell-like structure of the circular heating surface support into packages and fit into the individual cells of the heating surface support.
- the heating plates are packaged by solid boxes or frame brackets, which are placed around the heating plates bundled into the package. Both because of the more stable package position is mostly tangentially arranged heating plates it is common to have the heating plate packs parallel to their trapezoidal shape Hold the head ends together using head plates on the top and bottom are connected to each other via horizontally extending bars.
- the Heater plate packs follow the direction of gas flow, i.e. usually vertical arranged.
- the invention has for its object a heater plate package of the aforementioned Kind of simplify, especially with a weight-saving package holder without creating head plates and improved flow.
- the laminated core on at least two opposite sides of the package have a dimensionally stable exterior Has sandwich element for which differently profiled sheets alternately are arranged and form a pair of sheets, the profiled sheets of the pair of sheets firmly connected by welding spots and vertical Outer bars of the profiled sheets with horizontal bars on the top and bottom of the package are connected.
- the quasi box girder Outer profile sheet pairs ensure a sufficiently large stability, which thereby is still supported that vertical outer spars of the profiled sheets with horizontal spars on the top and bottom of the package are connected so that results in a belt-like spar wrap around the heating surface package.
- the sandwich-like hollow box girder composite Due to the sandwich-like hollow box girder composite, at least the two outer ones Profile sheets of the heating plate package will save weight above all, better utilization of the installation volume in the heating surface support and thus increasing the active heating area. Because contrary to The conventional head plate arrangements or peripheral frames are the profile sheets of the profile sheet pair (s) fully capable, like all the others Heating plates of the package as heating surfaces with the corresponding free ones Cross sections can be used in the entire area of the individual cells; the heating plate package thus offers higher heat output. Reduced at the same time the blockage in the flow cross-sections of the individual cells, so that there are lower flow losses for the heat exchanging media and achieve a lower pressure drop. The in the box girder sandwich composite unrestricted flow cross sections allow that Heating plate package if necessary on all sides, d. H. circumferentially closed with profile sheet pairs train and thus favor an even higher stability.
- the two Sheets of a pair of profiled sheets or several pairs of profiled sheets can be processed in an automatic process using the spot welding process Manufacturing process for the dimensionally stable hollow box girder composite body and thus connect to each other to the package-enclosing brackets, at the points where the sheets are spotted touch.
- Spot welding can happen as soon as the two profiled sheets, which are, for example, according to DE 41 22 949 Allow a method to become known, lie on top of each other.
- two or more profile sheets can be used alternatively by screwing or riveting together connect.
- the end faces are located the horizontal bars at the same height as the end faces the radial walls of the cells of the heating surface support.
- the regenerative heat exchanger designed as an air preheater according to FIG. 1 hot exhaust gas flows from a steam generator, not shown via a channel 2 to.
- the hot gas G flows in from above the regenerative heat exchanger 1, which in the exemplary embodiment in its central part is a circular, from the inside out in the Cross-section increasingly increasing trapezoidal segmented Has cells 13 (see FIG. 2) having heating surface supports 3. This takes 13 storage masses in the cells in the form of heating plate packs 4 (see FIG. 3).
- On both sides of the heating surface support 3 or the heating plate packs 4 are each segmented Hood 5, 6, which together continuously around a vertical axis 7 turn, because of the rotating movement always different parts the storage masses or heating plate packs 4 exposed to the hot gas G. are.
- Heater plate packs 4 are made up of numerous, different ones Profile sheets 14, 15 (see FIG. 4) assembled, of which the profiled sheets 14 are undulated and rolled deeper Have profiles and the profile sheets 15 are corrugated and have rolled profiles of lower height.
- the profile sheets 14, 15 are arranged alternately, and two profile sheets each 14, 15 are welded 16 to form a pair of profiled sheets 17, d. H. to form stable hollow box girder composite panels with each other connected, whereby - starting from the knock sides - always only that corrugated sheet 15 with the undulated sheet 14 welded in pairs becomes.
- 4 pairs of profiled sheets can be placed on each head side of the heating plate package 4 17 be spot welded, which depends on stability is freely variable.
- the dimensional stability guaranteed by the welding spots 16 becomes through vertical outer bars 20 on the outer profile sheet pairs 17 completed with the horizontal bars on the top and bottom of the package 21 are connected (see FIG. 3), so that the heating plate package 4 is wrapped around the circumference by two space-saving spar belts.
- the heating plate packs 4 can also be aligned radially Profile sheets 14, 15 are used, in which case the individual profile sheets 14, 15 parallel to the radial walls 22 of the Cells 13 of the heating surface support 3 extend.
- the extraordinarily high dimensional stability of the heating plate packs 4 creates the prerequisite that the outer end faces 23rd the upper and lower horizontal bars 21 at the same level can lie like the end faces 24 of the radial walls 22 of the cells 13 (see Fig. 7).
- the revolving rotary hoods 5, 6 the number of sealing lines per radial seal 25 and cell 13 increased, namely by the number of the existing horizontal spars 21.
- the one in the area of these seals volume flow exceeding due to the pressure gradient (cf. in Fig. 7 the flow arrows L for air and G for gas) are reduced due to the multiple sealing achieved, which one Leakage reduction equals.
