Definitions

  • the invention relates to a regenerative heat exchanger according to the type specified in the preamble of claim 1.
  • Regenerative heat exchangers of the type in question are used to transfer heat from at least one gas volume flow to at least one other gas volume flow.
  • a rotating heat storage the so-called rotor, alternately warmed up by at least one gas volume flow and cooled by at least one other gas volume flow again, wherein heat energy is transferred from one to the other gas volume flow.
  • the rotor has two end faces, an outer jacket and, as a rule, a segmentation for receiving the heat storage masses.
  • the rotor is rotatably mounted about a central axis of rotation, wherein this axis of rotation is preferably aligned vertically.
  • a sealing system with core, radial and / or circumferential seals is provided.
  • the radial seals are arranged on the front sides of the rotor and are intended to prevent short-circuit volume flows between the gas flow rates.
  • the circumferential seals are arranged on the front edges of the rotor and are intended to prevent leakage volume flows into the rotor housing or into the environment. These seals are arranged stationary with respect to the rotating rotor. Due to a permanent relative movement between the rotor and these seals, as well as a constantly changing thermal expansion of the rotor and associated uneven rotor deformations, high demands are placed on the sealing system in order to achieve low losses (leaks) and thus high efficiency.
  • An object of the invention is therefore to provide a regenerative heat exchanger of the type in question with a simple and effective sealing system.
  • the sealing system for the rotor has at least one fixed relative to the rotor seal, which is pressed on the one hand to the rotor or to a rotor belonging to the component (eg. By acting weights, spring cylinders, actuators and the like) and on the other hand, supported by a plurality of rollers on the rotatable rotor or on a component belonging to the rotor and thus primarily forced out in the axial direction.
  • the seal in question is subject to a quasi-forced operation, which in operation means that the seal in question with a constant and predetermined by the rollers distance of the thermally induced rotor deformation is continuously updated, whereby a small and constant sealing gap is ensured.
  • rollers are arranged in the fixed seal. Furthermore, it is provided that the rollers roll on at least one corresponding running or rolling surface on the rotor or a component belonging to the rotor or are guided between two corresponding and axially spaced-apart rolling surfaces. These rolling surfaces are interchangeable Wear plates formed, which are attached to the rotor (rotor body or a rotor-associated component). Likewise, a reverse arrangement of rollers and treads may be provided.
  • the individual rollers at least in the region and in particular only in the range of the control points or pressure points of the seal against the rotor are arranged.
  • the supported by rollers seal is preferably a radial seal.
  • the supported by rollers seal is in particular a peripheral seal. It is also possible at the same time to support both the radial seals and the peripheral seals at least on one rotor side by means of rollers on the rotating rotor.
  • At least one circumferential seal supported by rollers on the rotor is coupled to a radial seal on the same rotor side, such that the relevant radial seal is moved in the axial direction during axial movement of the peripheral seal.
  • the relevant radial seal is arranged to be movable in the axial direction.
  • the coupling between the peripheral seal and the radial seal is effected in particular by a mechanical adjusting mechanism which transmits the axial movements of the peripheral seal by means of at least one adjusting bar or the like to the relevant radial seal.
  • the sealing system on a rotor side can thus perform movements that follow the rotor movements in the axial direction.
  • This preferably radially extending adjusting bar is ideally arranged in the rotor housing of the regenerative heat exchanger and indeed between the respective radial seal and the housing wall, wherein in this area also a sealing collar can be arranged.
  • Fig. 1 shows a generally designated 1 regenerative heat exchanger, of which, however, only one half of symmetry is shown.
  • the regenerative heat exchanger 1 comprises a rotor 2, which is rotatably mounted about a vertical axis of rotation A and arranged in a rotor housing 3.
  • the rotor 2 is traversed by a plurality of gas flow rates V, wherein heat is transferred from at least one gas volume flow to at least one other gas volume flow.
  • V For sealing the guided through the regenerative heat exchanger 1 gas volume flows V is a sealing system with radial seals 4 and 5 circumferential seals provided.
  • the radial seals 4 are arranged on the end faces of the rotor 2 and are intended to prevent short-circuit volume flows between the gas volume flows V.
  • the circumferential seals 5 are arranged on the front edges of the rotor 2 and are intended to prevent leakage volume flows into the rotor housing 3.
  • the radial seals 4 and the circumferential seals 5 are arranged stationary with respect to the rotating rotor 2.
  • the radial seals 4 and the peripheral seals 5 preferably form, together with any core seals (not shown), a self-contained sealing frame.
  • the arranged on the upper end side and on the lower end face of the rotor 2 seals are formed substantially identical. The following explanations relate, unless otherwise stated, by way of example only to the upper seals and apply analogously to the lower seals.
  • the upper radial seal 4 is designed as a sealing plate and fastened or suspended in the axial direction by means of a plurality of evenly spaced actuators or spring cylinders 7, 8 and 9 on the rotor housing 3. (The lower radial seal 4 is supported accordingly with spring cylinders or the like.) Each spring cylinder 7, 8 or 9 represents a control point for the radial seal 4. Instead of the spring cylinder 7, 8 and 9 can also be worked with counterweights.
  • the radial seal 4 is formed in the radial direction with joints 41 and 42, which divide the radial seal 4 into several sections. The radial seal 4 can thus adapt to thermally induced rotor deformations. Alternatively, it is possible to perform the radial seal 4 jointless and flexible.
  • a sealing gap S With the smallest possible gap.
  • a sealing or expansion sleeve (see reference numeral 10 in the lower heat exchanger area) can be arranged, which compensates relative movements of the radial seal 4 relative to the housing wall.
  • the peripheral seal 5 is designed as an annular sealing frame and fastened or suspended with a plurality of circumferentially uniformly distributed actuators or spring cylinders 11 on the rotor housing 3.
  • the peripheral seal 5 can be segmented, executed with joints or jointless and flexible.
  • Each spring cylinder 11 represents a control point for the peripheral seal 5, wherein the peripheral seal 5, for example, is pressed against the rotor flange 6 as a result of a weight excess (weight force minus the actuating force in the spring cylinders 11).
  • the circumferential seal 5 is supported by means of a plurality of rollers 12 on the rotor flange 6 belonging to the rotor 2.
  • a roller 12 is provided at least in the region of each control point.
  • the rollers 12 are arranged in a recess in the peripheral seal 5 and preferably also rotatably mounted therein (eg. By means of an axis).
  • the rollers 12 roll on a wear plate 14 attached to the rotor flange 6.
  • the wear plate 14 is formed segmented in the circumferential direction.
  • Such a wear plate may also be provided on a corresponding rolling surface in the circumferential seal 5. It is also conceivable that the rollers 12 are guided sandwiched between two in the axial direction a spaced apart wear plates.
  • a mechanical coupling of the radial seals 4 with the peripheral seals 5 is provided both on the upper end side and on the lower end side of the rotor 2, to which the peripheral seals 5 and the radial seals 4 are non-positively connected.
  • the radial seals 4 follow the positively guided movement of the circumferential seals 5 in the axial direction a, for which purpose the radial seals 4 are movably mounted in the axial direction a.
  • the sealing of the rotor 2 is significantly improved and leaks are significantly reduced.
  • Fig. 2 shows an example in which, unlike the first embodiment of the Fig. 1 attached to the peripheral seal 5 rollers 12 between two axially spaced Rotor flanges 61 and 62 are guided with corresponding rolling surfaces. As a result, a "direct" positive guidance for the peripheral seal 5 is made possible. Otherwise, the explanations concerning the first exemplary embodiment of FIG Fig. 1 ,
  • a mechanical coupling of the circumferential seals 5 is also provided with the radial seals 4.
  • the circumferential seals 5 are each connected to a radially extending adjusting bar 16, which brings about a plurality of actuators 17, an adjustment of the respective radial seal 4 (on the same rotor side) in the axial direction a. D. h.
  • the positively driven movement of a peripheral seal 5 is transmitted according to the lever ratios to the relevant radial seal 4 and on the individual sections, including the radial seals 4 movably mounted in the axial direction or z. B. are also flexible.
  • the radially extending adjusting bars 16 are arranged in the interior of the rotor housing 3. Likewise, the adjusting bars 16 could also be arranged outside the rotor housing 3.
  • Fig. 4 shows a third embodiment in which the radial seals 4 are supported by means of rollers 18 on the end faces of the rotor 2.
  • the rollers 18 are arranged in the region of the control points or spring cylinders 7, 8 and 9.
  • At the end faces of the rotor 2 corresponding rolling surfaces are formed. These rolling surfaces may be formed on wear plates 19, as exemplified for the lower, radially inner roller 18.
