Description
Wärmeaustauschvorrichtung, insbesondere zur Erhitzung von Luft mittels Rauchgase, mit umlaufendem, hohlzylindrigem Speicherkörper Die Erfindung bezieht sich auf eine Wärmeaustauschvorrichtung zwischen zwei Gasen, z. B. zwischen Rauchgasen und Luft, bei der ein Speicherkörper derart von dem einen Gasstrom zum anderen wandert, daß er abwechselnd Wärme von dem einen Gasstrom aufnimmt und an den anderen abgibt.Heat exchange device, in particular for heating air by means of Flue gases, with a circumferential, hollow-cylindrical storage body The invention relates relate to a heat exchange device between two gases, e.g. B. between flue gases and air, in which a storage body migrates from one gas flow to the other in this way, that it alternately absorbs heat from one gas stream and transfers it to the other.
Zu diesem Zwecke sind bereits Vorrichtungen mit umlaufendem, hohlzylinderförmigem Speicherkörper bekannt, der in die die beiden Gasströme trennende Wand eingebaut und mittels einer in einer Axialebene durch den inneren Hohlraum hindurchgeführte Trennwand in zwei gegeneinander abgeschlossene Räume geteilt ist.For this purpose devices with a circumferential, hollow cylinder-shaped Storage body known, which is built into the wall separating the two gas flows and by means of a guided through the inner cavity in an axial plane Partition wall is divided into two mutually closed rooms.
Um bei Wärmeaustauschv orrichtungen dieser Art =große Durchgangsquerschnitte für die Gase im Speicherkörper zu erzielen, ist nach der Erfindung die Achse des umlaufenden Speicherkörpers senkrecht zur Strömungsrichtung der Gase gelegt, und beide Gasströme durchziehen den rost- oder gitterförmig ausgebildeten Speicherkörper während seiner Drehbewegung in radialer Richtung zunächst von außen nach innen und dann von innen nach außen. Der Speicherkörper kann bei verhältnismäßig geringem Durchmesser in axialer Richtung so bemessen werden, daß den durchströmenden. Gasen reichliche Durchgangsquerschnitte geboten werden. Infolgedessen wird es möglich, bei geringstem Widerstand des Speicherkörpers gegen die Gasbewegung und bei geringstem Raum- und Gewichtsbedarf sowie einfachstem Bau der Anlage einen guten Wärmeaustausch zwischen den beiden völlig getrennt bleibenden Gasströmen zu erreichen. .To with heat exchange devices of this type = large passage cross-sections to achieve for the gases in the storage body, according to the invention, the axis of the circumferential storage body placed perpendicular to the direction of flow of the gases, and Both gas streams run through the grate-shaped or grid-shaped storage body during its rotary movement in the radial direction initially from the outside to the inside and then inside out. The storage body can with relatively little Diameter in the axial direction are dimensioned so that the flowing through. Gases ample passage cross-sections are offered. As a result, it becomes possible with the lowest resistance of the storage body to the gas movement and with the lowest Space and weight requirements as well as the simplest construction of the system a good heat exchange to achieve between the two completely separate gas streams. .
Die Erfindung ist in der Zeichnung veranschaulicht, und zwar in Abb. I im Längsschnitt und in Abb. z teils im Querschnitt nach der Linie A-B, teils in Ansicht von oben.The invention is illustrated in the drawing, namely in Fig. I in longitudinal section and in Fig. Z partly in cross section along the line A-B, partly in View from above.
Abb.3 zeigt die Anordnung der Rostplatten des Speicherkörpers in zwei verschiedenen Ausführungen.Fig.3 shows the arrangement of the grate plates of the storage body in two different designs.
Abb. d. veranschaulicht die Verbindung der Platten miteinander.Fig. D. illustrates the connection between the panels.
In den Abbildungen bedeutet i einen Rauchgaskanal, während mit a der Frischluftzuführungskanal bezeichnet ist. Zwischen beiden Kanälen befindet sich die Trennwand 3. Diese ist in der Weise durchbrochen, daß der drehbare, als Hohlzylinder . ausgebildete Speicherkörper q. von dem einen in den anderen Kanal wandern kann. Im Innenraum 5 des Speicherkörpers 4. ist die sich in der Zylinderlängsachse erstreckende Trennwand 6 derart angeordnet, daß sie die Fortsetzung der Trennwand 3 bildet.In the figures, i means a flue gas duct, while with a the Fresh air supply duct is designated. Between the two channels is the partition wall 3. This is perforated in such a way that the rotatable, as a hollow cylinder . trained storage body q. can migrate from one canal to the other. In the interior 5 of the storage body 4 is the one extending in the longitudinal axis of the cylinder Partition 6 arranged in such a way that it forms the continuation of partition 3.
Da es notwendig ist, zwischen den feststehenden Wänden der Gasführungskanäle und der Wand 6 einerseits und dein rotierenden Speicherkörper andererseits sicher arbeitende Abdichtungen anzuordnen, sind an sich bekannte federnde Dichtungen 7 und 8 vorgesehen, welche sich an den rotierenden Speicherkörper während seiner Umdrehung auch dann fest anlegen, wenn der letztere keine gleichmäßige Rundung besitzt. Der Speicherkörper kann auf beliebige Weise um seine Achse g in Drehung versetzt werden. Es ist jedoch zweckmäßig, die Drehung in bekannter Weise auf hydraulischem Wege mittels eines Klinkenradgesperres io, i i, 12 zu bewirken. Letzteres wird durch einen unter Wirkung von Druckwasser stehenden Kolben 13 hin- und durch eine Feder 14 zurükgetrieben. Der Hohlzylinder 4 besitzt auf seinem Umfange rostartig gestellte Platten 15 bzw. 15a, welche, wie Abb. 3 zeigt, entweder in Form ebener Platten oder derart gekrümmt ausgeführt werden können, daß sie bei durchgehend gleichem Abstand voneinander den ganzen Trommelrand ausfüllen. Durch die letztere Ausführungsform wird der Vorteil erzielt, daß bei gleichem. Raum eine vergrößerte Wärmeaustauschoberfläche untergebracht werden kann. Die Rostplatten i5a sind zweckmäßigerweise in einzelnen, radial angeordneten Paketen (vgl. Abb.3, linke Seite) untergebracht. Der Abstand zwischen den einzelnen Rostplatten wird durch' irr Schlangenform um sie herumgeführte und an den Kanten befestigte Drähte 16, 16', 16" gehalten. In den sektorförmigen Zwischenraum zwischen je zwei Paketen von Rostplatten 15 finden die zum Zusammenhalten des ganze. Speicherkörpers dienenden Verbindungsbolzen 17 Aufnahme.Since it is necessary to arrange reliably working seals between the fixed walls of the gas ducts and the wall 6 on the one hand and the rotating storage body on the other hand, resilient seals 7 and 8, known per se, are provided which then firmly attach to the rotating storage body during its rotation if the latter is not evenly rounded. The storage body can be set in rotation about its axis g in any desired manner. However, it is expedient to effect the rotation in a known manner in a hydraulic manner by means of a ratchet wheel locking mechanism io, ii, 12. The latter is driven back and forth by a piston 13 under the action of pressurized water and by a spring 14. The hollow cylinder 4 has on its circumference rust-like plates 15 and 15a, which, as Fig. 3 shows, can be designed either in the form of flat plates or curved in such a way that they fill the entire edge of the drum with the same distance from one another. The latter embodiment has the advantage that with the same. Space an enlarged heat exchange surface can be accommodated. The grate plates i5a are expediently housed in individual, radially arranged packages (see Fig. 3, left side). The distance between the individual grate plates is 'irr snake form guided around them and fastened at the edges of the wires 16, 16' held 16 ". See the sector-shaped space between two packets of grate plates 1 5, which serves to hold together the whole. Storage body Connecting pin 17 receptacle.
Die Wirkungsweise der Vorrichtung ist folgende: Die den Kanal i durchziehenden Rauchgase treten in den Innenraum 5 des Hohlzylinders 4 in radialer Richtung ein und geben einen erheblichen Teil ihrer Wärme an den den Rauchgaskanal gerade durchwandernden Teil der Wärmeaustauschvorrichtung ab. * In der gleichen Zeit wird der im Luftzuführungskanal 2 befindliche Teil der Wärmeaustauschvorrichtung in radialer Richtung von der Frischluft durchstrichen, wobei die Trennwand 6 und die federnden Dichtungen 8' ein Vermischen der beiden Luftströme im Innenraum 5 der Wärmeaustauschvorrichtung verhindern. Infolge der langsamen Drehung des Wärmespeichers 4 gelangen die erwärmten Rostplatten 15 nacheinander aus dem Abgaskanal i in den Frischluftkanal 2, um dort ihre Wärme an die Frischluft abzugeben, so daß letztere beim Verlassen der Wärmeaustauschvorrichtung hoch erhitzt ist.The mode of operation of the device is as follows: The one running through the channel i Flue gases enter the interior 5 of the hollow cylinder 4 in the radial direction and give a considerable part of their heat to the person just wandering through the flue gas duct Part of the heat exchange device. * At the same time, the air supply duct is activated 2 located part of the heat exchange device in the radial direction of the fresh air crossed out, the partition 6 and the resilient seals 8 'mixing Prevent the two air flows in the interior 5 of the heat exchange device. As a result The heated grate plates 15 reach the slow rotation of the heat accumulator 4 one after the other from the exhaust duct i into the fresh air duct 2 in order to get their heat there to release the fresh air, so that the latter when leaving the heat exchange device is highly heated.
