Description
Die Erfindung betrifft einen Regenerativ-Wärmeaustauscher mit einer wärmetauschenden, mit einer Vielzahl von Strömungskanälen versehenen Speichermasse und stirnseitig je einer Haube, die die Speichermasse mittels radialer Dichtleisten in mindestens jeweils einen mit wärmeabgebenden und einen mit wärmeaufnehmenden Gasen beaufschlagten Teil unterteilt, die durch eine kontinuierliche Drehbewegung zwischen Speichermasse und Hauben abwechselnd mit den beiden Gasen beaufschlagt werden, wobei am Umfang zwischen den Hauben und einem die Speichermasse aufnehmenden Gehäuse ebenfalls Dichtieisten angeordnet sind und die radialen Dichtleisten mit unmittelbar mit der ebenen Stirnfläche der Speichermasse als Spaltdichtungen zusammenwirkenden Dichtschenkeln ausgebildet sind.The invention relates to a regenerative heat exchanger with a heat-exchanging storage mass provided with a multiplicity of flow channels and on the end face of a hood which divides the storage mass into at least one part with heat-emitting and one with heat-absorbing gases by means of radial sealing strips, which part is subjected to a continuous rotary movement between the storage mass and the hoods are alternately charged with the two gases, sealing gaskets also being arranged on the circumference between the hoods and a housing receiving the storage mass and the radial sealing strips being formed with sealing legs that interact directly with the flat end face of the storage mass as gap seals.
Ein derartiger Regenerativ-Wärmetauscher ist aus der US-A-39 07 310 bekannt. Bei dieser vorbekannten Konstruktion werden die radialen Dichtleisten zwar federnd in Richtung der ebenen Stirnfläche der Speichermasse belastet, liegen jedoch mit ihrem Dichtelement nicht an der Stirnfläche der Speichermasse an, sondern werden mit Hilfe von kreisförmigen Abstandshaltern in einem vorgegebenen, geringfügigen Abstand von der Stirnfläche der Speichermasse gehalten, so dass sie als Spaltdichtungen wirken.Such a regenerative heat exchanger is known from US-A-39 07 310. In this known construction, the radial sealing strips are resiliently loaded in the direction of the flat end face of the storage mass, but do not rest with their sealing element on the end face of the storage mass, but are instead with the aid of circular spacers at a predetermined, slight distance from the end face of the storage mass held so that they act as gap seals.
Da insbesondere die Anströmkanten der in der Speichermasse ausgebildeten Strömungskanäle verschmutzen oder sogar verstopfen, ist es bei dieser bekannten Konstruktion erforderlich, die wärmetauschende Speichermasse von Zeit zu Zeit mittels eines Reinigungsfluids zu reinigen. Da Verstopfungen in vielen Fällen nicht mehr durch ein Reinigungsfluid beseitigt werden können, wird es in grösseren Zeitabständen notwendig, den Regenerativ-Wärmeaustauscher stillzusetzen und die Speichermasse mechanisch zu reinigen.Since in particular the leading edges of the flow channels formed in the storage mass become soiled or even clogged, it is necessary in this known construction to clean the heat-exchanging storage mass from time to time by means of a cleaning fluid. Since blockages can in many cases no longer be removed by a cleaning fluid, it becomes necessary at longer intervals to shut down the regenerative heat exchanger and to mechanically clean the storage mass.
Der Erfindung iiegtdieAufgabe zugrunde, einen Regenerativ-Wärmeaustauscher der eingangs beschriebenen Art derart weiterzubilden, dass bei gleichzeitiger Konstruktionsvereinfachung und Verbesserung der Abdichtwirkung die bisher periodisch notwendige Reinigung der Speichermasse entfällt.The invention is based on the object of developing a regenerative heat exchanger of the type described at the outset in such a way that, while simplifying the construction and improving the sealing effect, the periodically necessary cleaning of the storage mass is eliminated.
Die Lösung dieser Aufgabenstellung durch die Erfindung ist dadurch gekennzeichnet, dass die Dichtleisten über ihre gesamte Länge mit einem unmittelbar an der Speichermasse anliegenden und eine mechanische Reinigung der Anströmkanten der Speichermasse bewirkenden Abdichtelementversehen sind, das durch eine Vielzahl von in einem Tragkörper gehaltenen Borsten gebildet ist und an den Längskanten der Dichtleisten von den aus einem im Verhältnis zum Material der Speichermasse weicheren Material bestehenden Dichtschenkeln eingefasst ist.The solution to this problem by the invention is characterized in that the sealing strips are provided over their entire length with a sealing element which is in direct contact with the storage mass and causes mechanical cleaning of the leading edges of the storage mass and which is formed by a multiplicity of bristles held in a supporting body and is bordered on the longitudinal edges of the sealing strips by the sealing legs, which consist of a material that is softer in relation to the material of the storage mass.
Durch diese erfindungsgemässe Ausbildung wird nicht nur die Abdichtwirkung verbessert, da zusätzlich zu den in der Art einer Labyrinthdichtung wirkenden Tragkörpern unmittelbar mit der Stirnfläche der Speichermasse zusammenwirkende Borsten vorgesehen sind, sondern es wird auch eine ständige Reinigung der Stirnfläche der Speichermasse durch die Vielzahl der Borsten erzielt, so dass auf die bei den bekannten Konstruktionen erforderliche, in gewissen Abständen erfolgende mechanische Reinigung der Anströmkanten der Speichermasse verzichtet werden kann.This configuration according to the invention not only improves the sealing effect, since in addition to the supporting bodies acting in the manner of a labyrinth seal, bristles which interact directly with the end face of the storage mass are provided, but also a permanent cleaning of the end face of the storage mass is achieved by the large number of bristles , so that the mechanical cleaning of the leading edges of the storage mass which is required at certain intervals in the known constructions can be dispensed with.
Aus der G B-A-21 19 037 war zwar ein Regenerativ-Wärmeaustauscher mit Dichtungen bekannt, die aus mit Borsten bestückten Dichtleisten bestehen. Diese Dichtleisten wirken jedoch entweder mit der Umfangsfläche des die Speichermasse aufnehmenden Gehäuses oder mitzusätzlichen radialen Speichen zusammen, die in axialer Richtung aus der ebenen Stirnfläche der Speichermasse herausragen. Aus diesem Grunde haben die radialen Dichtungen eine derart grosse Breite, dass sie jeweils komplett einen der Sektoren überdecken, in die die Speichermasse durch die radialen Speichen unterteilt ist. Hierdurch ergibt sich jedoch eine unerwünschte Verkleinerung der mit dem wärmeabgebenden bzw. dem wärmeaufnehmenden Gas beaufschlagten Teile der Speichermasse. Ausserdem wird bei der bekannten Konstruktion keinerlei Reinigungswirkung durch die Borsten erzielt. Es ist somit auch bei dieser bekannten Konstruktion in gewissen Zeitabständen eine Reinigung der Speichermasse einerseits mit Reinigungsfluid und andererseits auf mechanischem Wege erforderlich.From G B-A-21 19 037 a regenerative heat exchanger with seals was known, which consist of sealing strips fitted with bristles. However, these sealing strips interact either with the peripheral surface of the housing receiving the storage mass or with additional radial spokes which protrude in the axial direction from the flat end face of the storage mass. For this reason, the radial seals have such a large width that they each completely cover one of the sectors into which the storage mass is divided by the radial spokes. However, this results in an undesirable reduction in the size of the parts of the storage mass which are exposed to the heat-emitting or the heat-absorbing gas. In addition, no cleaning effect is achieved by the bristles in the known construction. In this known construction, cleaning of the storage mass with cleaning fluid on the one hand and on the other hand by mechanical means is therefore necessary at certain time intervals.
Bei der erfindungsgemässen Ausbildung wird das federnde Andrücken der Dichtleisten durch die Ausnutzung der elastischen Materialeigenschaften der Borsten erzielt. Diese bilden ein hochelastisches Element sowohl für die Abdichtung als auch für die Reinigung und sind darüber hinaus in der Lage, sich an Unebenheiten der Stirnflächen der Speichermasse problemlos anzupassen, ohne die Speichermasse zu beschädigen. Da die zusätzlich in der Art von Spaltdichtungen wirkenden Dichtschenkel, welche die im Tragkörper gehaltenen Borsten einfassen, aus einem im Verhältnis zum Material der Speichermasse weicheren Material bestehen, können die Dichtschenkel verhältnismässig dicht an die Stirnfläche der Speichermasse herangeführt werden, ohne dass die Gefahr einer Beschädigung der Speichermasse besteht. Schliesslich können die im Tragkörper gehaltenen Borsten und ggf. die Dichtschenkel auf einfache Weise ausgewechselt werden. Ein weiterer Vorteil der erfindungsgemässen Ausgestaltung besteht darin, dass die erfindungsgemässen Dichtleisten eine vernachlässigbar kleine Behinderung der Strömung für die beiden wärmeaustauschenden Gase darstellen.In the embodiment according to the invention, the resilient pressing of the sealing strips is achieved by utilizing the elastic material properties of the bristles. These form a highly elastic element for both sealing and cleaning and are also able to adapt to unevenness in the end faces of the storage mass without damaging the storage mass. Since the sealing legs, which act in the manner of gap seals and which enclose the bristles held in the supporting body, consist of a material which is softer in relation to the material of the storage mass, the sealing legs can be brought closer to the end face of the storage mass without the risk of damage the storage mass exists. Finally, the bristles held in the support body and possibly the sealing legs can be replaced in a simple manner. Another advantage of the configuration according to the invention is that the sealing strips according to the invention represent a negligibly small impediment to the flow for the two heat-exchanging gases.
Die erfindungsgemässe Ausbildung kann insbesondere an Regenerativ-Wärmeaustauschern zur Aufheizung der Reingase hinter Entschwefelungsanlagen sowie zur Luftvorwärmung sowie generell bei Regenerativ-Wärmeaustauschern mit stark verschmutzenden Anströmkanten der Speichermasse verwendet werden.The design according to the invention can be used in particular on regenerative heat exchangers for heating the clean gases behind desulfurization systems and for air preheating, and in general in regenerative heat exchangers with strongly contaminating leading edges of the storage mass.
Auf der Zeichnung ist ein Ausführungsbeispiel eines Regenerativ-Wärmeaustauschers gemäss der Erfindung dargestellt, und zwar zeigen:
- Fig. 1 eine perspektivische Ansicht der Speichermasse und einer Haube eines im übrigen nicht dargestellten Regenerativ-Wärmeaustauschers und
- Fig. 2 einen Teilschnitt durch eine radiale Dichtung der Haube gemäss der Schnittlinie 11-11 in Fig. 1.
- Fig. 1 is a perspective view of the storage mass and a hood of an otherwise not shown regenerative heat exchanger and
- 2 shows a partial section through a radial seal of the hood according to section line 11-11 in FIG. 1.
Bei dem als Ausführungsbeispiel schematisch dargestellten Regenerativ-Wärmeaustauscher nach Fig. 1 steht die mit einer Vielzahl von Strömungskanälen versehene Speichermasse 1 still, wogegen die der besseren Erkennbarkeit wegen im Abstand von der ebenen Stirnfläche der Speichermasse 1 gezeichnete Haube 2 drehend angetrieben ist. Selbstverständlich ist es auch möglich, die Haube 2 stillzusetzen und die Speichermasse 1 drehend anzutreiben.In the regenerative heat exchanger shown schematically as an exemplary embodiment according to FIG. 1, the
Um eineAbdichtung zwischen Speichermasse 1 und Haube 2 zu erzielen und während der relativen Drehbewegung die Speichermasse 1 ständig in mindestens jeweils einen mit wärmeabgebenden und einen mit wärmeaufnehmenden Gasen beaufschlagten Teil zu unterteilen, ist die Haube 2 mit radial verlaufenden Dichtleisten 3 versehen. Beim Ausführungsbeispiel sind vier jeweils über die Länge des Radius verlaufende Dichtleisten 3 vorgesehen, die in der Art eines Kreuzes angeordnet sind und jeweils zwei einander bezüglich des Drehmittelpunktes gegenüberliegende Kanäle einerseits für das wärmeabgebende und andererseits für das wärmeaufnehmende Gas bilden. Die jeweils zwischen zwei radial verlaufenden Dichtleisten 3 am Umfang der Haube 2 vorhandenen Kreisbögen sind ebenfalls mit Dichtungen 4 versehen, die beim Ausführungsbeispiel aus einzelnen Stücken zusammengesetzt sind.In order to achieve a seal between the
Wie aus dem Teilschnitt gemäss Fig. 2 hervorgeht, liegen die radial verlaufenden Dichtleisten 3 unmittelbar an der jeweiligen ebenen Stirnfläche der Speichermasse 1 federnd an. Die Dichtleisten 3 besitzen ein eigenelastisches Abdichtelement 6, das durch eine Vielzahl von in einem Tragkörper 5 gehaltenen Borsten gebildet ist. Diese Borsten sind an den Längskanten der Dichtleisten 3 von als Spaltdichtungen ausgebildeten Dichtschenkeln 7 eingefasst. Diese Dichtschenkel 7 bestehen aus einem im Verhältnis zum Material der Speichermasse 1 weicheren Material, so dass ihre der Speichermasse 1 zugewandten Kanten verhältnismässig nahe an die Speichermasse 1 herangeführt werden können, ohne dass die Gefahr einer Beschädigung der Speichermasse 1 besteht. Hierdurch wird bereits durch die Dichtschenkel 7 eine gute Abdichtwirkung erzielt, die durch die Borsten des Abdichtelements 6 unterstützt wird. Diese Borsten 6 sorgen beim Umlauf der Haube 2 relativ zur Speichermasse 1 schliesslich dafür, dass die Anströmkanten der Speichermasse 1 ständig mechanisch saubergehalten werden.As can be seen from the partial section according to FIG. 2, the radially extending
Beim Ausführungsbeispiel nach Fig. 2 sind die Dichtschenkel 7 an einem Tragprofil 8 gemeinsam mit dem Tragkörper 5 und den Borsten 6 angeordnet. DiesesTragprofil8 8 istan einem Abschlussprofil 9 angeordnet, das wiederum an einem aus zwei U-Profilen gebildeten Kammerprofil 10 der Haube 2 befestigt ist.2, the
Wie die Fig. 1 erkennen lässt, sind beim Ausführungsbeispiel durch die am Umfang der Haube 2 angeordneten Dichtungen 4 in der mit Bezug auf Fig. 2 beschriebenen Art aus einem mit Borsten versehenen Tragkörper ausgebildet. Selbstverständlich ist es möglich, die Dichtleisten 3 und die Dichtungen 4 unterschiedlich auszuführen, da ausschliesslich die Dichtleisten 3 neben ihrer Dichtfunktion eine Reinigungswirkung erzeugen sollen.As can be seen in FIG. 1, in the exemplary embodiment the seals 4 arranged on the circumference of the
