Description

Gegenstromwärmeaustauscher, dissen Rohre und dessen Kanäle zwischen diesen gleichen Querschnitt und gleiche Gestalt haben Die Erfindung betrifft einen Gegenstromwärmeaustauscher dessen Rohre für den Durchgang des einen Wärmeaustauschmittels und dessen Kanäle zwischen diesen für das andere Mittel ungefähr gleichen Querschnitt und gleiche Gestalt haben. Das Kennzeichen der Erfindung liegt darin, daß die Durchgangsrohre quadratischen Querschnitt haben und ferner darin, daß sich die Durchgangsrohre entlang ihren Kanten berühren und hier verlötet oder verschweißt sind. Diese Form des Querschnittes hat den. besonderen Vorzug eines guten Wärmeaustausches und. gleichzeitig einer leichten Reinigungsmöglichkeit der Zwischenräume zwischen den Rohren. Letztere ist von besonderer Bedeutung bei solchen Wärmeaustauschern, bei denen sich aus dem in Betrieb genommenen Medium Bestandteile ausscheiden, die sich an den Wänden der Rohre leicht festsetzen und nicht etwa durch Auftauen oder Erwärmen, sondern nur durch mechanische Mittel beseitigt werden können.Countercurrent heat exchangers, dissecting tubes and their channels between have this same cross-section and the same shape. The invention relates to one Countercurrent heat exchanger whose tubes for the passage of one heat exchange medium and its channels between them for the other means approximately the same cross-section and have the same shape. The feature of the invention is that the through pipes have a square cross-section and also in that the through-tubes extend along touch their edges and are soldered or welded here. This shape of the cross-section has the. special advantage of a good heat exchange and. at the same time one easy cleaning of the spaces between the pipes. The latter is of particular importance in such heat exchangers, in which the in The medium that is put into operation excrete components that are deposited on the walls of the pipes set easily and not by thawing or warming, but only through mechanical means can be eliminated.

In der Zeichnung ist eine Ausführungsform des Erfindungsgegenstandes beispielsweise veranschaulicht.In the drawing is an embodiment of the subject matter of the invention for example illustrated.

Fig. i ist ein Längsschnitt durch den Oberteil eines Wärmeaustauschers, der in Fig. 2 vervollständigt und gleichzeitig für das Einführen von Reinigungswerkzeugen eingerichtet ist.Fig. I is a longitudinal section through the top of a heat exchanger, which in Fig. 2 is completed and at the same time for the introduction of cleaning tools is set up.

Fig.3 und q. sind Querschnitte nach x-x und y-y.Fig. 3 and q. are cross-sections according to x-x and y-y.

In dem säulenförmigen Behälter a befindet sich ein aus im Querschnitt quadratischen Rohren b bestehendes Bündel. Die Rohre b sind an ihren Kanten miteinander vereinigt, z. B. verlötet oder verschweißt, und lassen quadratische Zwischenräume d. zwischen sich. An ihren oberen und unteren Enden verjüngen sich die Rohre auf zylindrische Stücke bi, die in Böden e1, e2 eingelassen sind. Die Böden e1, e2 trennen den Behälter a von einem Aufsatz, f- und einem Untersatz g. Das bei la im unteren Teil des Behälters a warm ankommende Gas strömt durch die Kanäle d und innen an dem Mantel des Behälters a entlang, tritt durch die Leitung i in einen Kältespeicher m, beispielsweise einen durch eine Ammoniakschlange s gekühlten Raum, strömt mit erniedrigter Temperatur dann aus dieseln durch die Leitung k hindurch in den Aufsatz f sowie von hier aus durch die Rohre b1, b hindurch, also dem durch die Kanäle d aufsteigenden wärmeren Gas entgegen, um dann den Behälter a durch den Stutzen y zu verlassen. ` Die zylindrischen Rohrenden b1 sind notwendig, um die Viereckröhre überhaupt verankern zu können; sie haben aber noch, wie Fig. 2 zeigt, den Vorteil, daß sie die Reinigung der Rohre und Kanäle erleichtern. Hierzu hat der Boden e1 zwischen den Enden b1 Bohrungen o Jiir das Einführen der Werkzeuge in die Kanäle d. Eine auf dem Boden e1 aufliegende Platte p verhindert ein Vermischen des warmen und kalten Gases. Um auch die Rohre selbst reinigen zu können, hat die Platte p öffnungen n in Achsenrichtung der. Rohre und von .der Lichtweite derselben. Diese Platte wird weggenommen, wenn die Kanäle d durch die öffnungen o hindurch gereinigt werden sollen.In the columnar container a there is a bundle consisting of tubes b with a square cross section. The tubes b are united at their edges, z. B. soldered or welded, and leave square spaces d. between them. At their upper and lower ends, the tubes taper to cylindrical pieces bi, which are embedded in floors e1, e2. The bottoms e1, e2 separate the container a from a top, f and a base g. The warm gas arriving at la in the lower part of the container a flows through the channels d and along the inside of the jacket of the container a, passes through the line i into a cold store m, for example a room cooled by an ammonia coil s, flows at a reduced temperature then from diesels through the line k into the attachment f and from here through the tubes b1, b through, so the warmer gas rising through the channels d , in order to then leave the container a through the nozzle y. `The cylindrical tube ends b1 are necessary in order to be able to anchor the square tube at all; however, as shown in FIG. 2, they still have the advantage that they facilitate cleaning of the pipes and channels. For this purpose, the base e1 has bores between the ends b1 for inserting the tools into the channels d. A plate p lying on the floor e1 prevents the warm and cold gas from mixing. In order to be able to clean the pipes themselves, the plate p has openings n in the axial direction of the. Tubes and of .the clear width of the same. This plate is removed when the channels d are to be cleaned through the openings o.
