Description
Wärmetauscheinrichtung in Verbindung mit einer Fliehkrafttrenneinrichtung Es sind bereits VVärmetauscheinrichtungen in @"erbindung mit Fliehkrafttrenneinrichtungen bekan»t, bei denen die Wärmetauschmittel in einzelne parallele Teilströme -aufgeteilt, durch geschlossene rohrförmige Kanäle an zylindrisch gekrümmten @'färmetauschflächen vorbeigeführt sind und mindestens die Bahn eines Wärmetauschmittels in bezug auf die zylindrische Wärmetauschfläche schraubenförmig verläuft und durch die gekrümmte Führung der Wärmetauschmittel eine Fliehkrafttrennung erfolgt. Diese bekannten Einrichtungen entsprechen nicht voll den Anforderungen der Praxis. Insbesondere wird nach der erfolgten Fliehkrafttrennung eineAusscheidungder spezifisch schwereren N4edienteilchen entweder gar nicht oder in räumlich getrennten besonderen Abscheideranlagen durchgeführt. Erfolgt keine Abscheidung, so treten am Ende der bekannten Anlagen mit spezifisch schweren 'Medienteilchen beladene Wärmetauschmittel, also z. B. mit Staub verunreinigte Verbrennungsgase, aus. Bei einer Reinigung in räumlich getrennten besonderen Abscheideranlagen sind die Kosten für den Bau und den Betrieb solcher getrennter Anlagen hoch. Durch die erforderlichen Rohrleitungen und Umlenkung der Medienströme ist fernerhin in nachteiliger Weise ein Druckverlust bedingt. Sämtliche olxugenannten L'nzuköniniliclil<eiten «-erden gemäß der Erfindung dadurch vennieden, daß zur Ausscheidung spezifisch schwerer @fediciiteilchen dein Wännetauschdrallfeld nachgeschaltete Schleuderkainniern angeordnet sind und daß zum Abziehen des XIediuiiistronies mit den spezifisch leichteren Medienteilchen ein vorzugsweise achszentrales Rohr ani Austritt jeder Schleuderkaninier vorgesehen ist. 'Nach einem weiteren Kennzeichen der Erfindung erfolgt die die Fliehkrafttrennung bewirkende gekrümmte Führung der Wärmetauschmittel nur über einen Teil der gesamter, Einrichtung. so daß innerhalb der Einrichtung noch ein Raum zur Einführung des vorzugsweise achszentralen Rohres frei bleibt.Heat exchange device in connection with a centrifugal separator There are already V heat exchange devices in connection with centrifugal separation devices known, in which the heat exchange medium is divided into individual parallel partial flows, through closed tubular channels on cylindrically curved heat exchange surfaces are passed and at least the path of a heat exchange medium with respect to the cylindrical heat exchange surface runs helically and through the curved A centrifugal separation takes place through the heat exchange medium. These well-known bodies do not fully meet the requirements of practice. In particular, after the If centrifugal separation occurred, the specifically heavier nitrogen particles were separated out either not carried out at all or in spatially separate special separator systems. If there is no separation, the known systems with specific occur at the end heavy 'media particles laden heat exchange medium, so z. B. contaminated with dust Combustion gases, from. When cleaning in spatially separate special separator systems the cost of building and operating such separate facilities is high. By the necessary pipelines and diversion of the media flows is also in disadvantageously caused a pressure loss. All olxu named L'nzuköniniliclil <eiten "-erden according to the invention by the fact that for Elimination of specifically heavy @fediciiteilchen downstream of your heat exchange swirl field Schleuderkainniern are arranged and that to pull off the XIediuiiistronies with the specifically lighter media particles an axially central tube ani Each centrifugal rabbit outlet is provided. 'After another license plate the invention takes place the centrifugal separation causing the curved guidance of the Heat exchange medium only over part of the entire facility. so that within the device still has a space for the introduction of the preferably axially central tube remains free.
In der Zeichnung ist der Gegeiistaiid der Erfindung in einer einzigen Figur beispielsweise dargestellt. Die Zeichnung ist schematisch gehalten Nach diesem Ausführungsbeispiel strömt zu rcinigendcs heißes Rohgas gemäß Pfeil b in die Anlage ein. Nach der @'t'ärmea bgal>e und einer Fliehkrafttrennung verläßt das Reingas die gesamte Einrichtung gemäß Pfeil 9 durch das Reingasrohr z. Bei 13 wird der Staub ausgetragen. Im wesentlichen im Gegenstrom dazu läßt man nach Pfeil io kalte Luft einströmen, die bei ii als vorgeil-ärnite Verbrennungsluft abgeht.In the drawing, the Gegeiistaiid of the invention is in a single one Figure shown for example. The drawing is kept schematic after this Embodiment flows to rcinigendcs hot raw gas according to arrow b into the system a. After the @ 't'ärmea bgal> e and a centrifugal separation, the clean gas leaves the entire device according to arrow 9 through the clean gas pipe z. At 13 the dust becomes carried out. Essentially in countercurrent to this, cold air is left as indicated by the arrow 10 flow in, which goes off as vorgeil-arnite combustion air at ii.
Das bei S einströmeu<lc heiße Rohgas wird durch den Nebenkörper 12 und durch die Kanäle; gezwungen, sich fortzubewegen. Dabei findet eine Fliehkrafttrennung statt, derart, <laß die spezifisch schweren Staubteilchen außen strömen und so die Innenflächen der Strömungsberandung reinhalteai. Am Ende des Strömungsweges ist dem Wärmetauschdrallfeld eine Schleuderkammer i nachgeschaltet, in der wie in einem bekannten Fliehkraftabscheider eine vollständige Trennung der spezifisch schwereren Medienteilchen erfolgt, die bei 13 abgeschieden werden. Das Beingas verläßt, wie schon gesagt, bei 9 die Anlage. Das im Gegenstrom geführte Medium geht durch die Rohre 6. Es nimmt dabei von dem innen strömenden Medium leicht -@@,ärme auf, da, wie oben auseinandergesetzt, die innere Strömungsberandung stets blank gehalten wird, was für den Wärmeübergang wesentlich ist. Die Kanäle 6 sind durch Rippen 4 gegeben, über die Abdeckmittel 5 gestülpt sind.The hot raw gas flowing in at S is passed through the secondary body 12 and through the channels; forced to move. There is a centrifugal separation instead of, like that, <let the specifically heavy dust particles flow outside and so on keep the inner surfaces of the flow boundary clean ai. At the end of the flow path a centrifugal chamber i is connected downstream of the heat exchange swirl field, in which as in a known centrifugal separator a complete separation of the specifically heavier ones Media particles takes place, which are deposited at 13. The beingas leave how already said, at 9 the system. The countercurrent medium passes through the Pipes 6. It absorbs the medium flowing inside easily - @@, poor, there, as explained above, the inner flow boundary always kept bare becomes what is essential for heat transfer. The channels 6 are formed by ribs 4 given, over the covering means 5 are slipped.
«-ie man aus der Zeichnung ersieht, erfolgt für das innen strömende '\Zediuin die die Fliehkrafttrennung bewirkende gekrümmte Führung nur über einen Teil 3 der gesamten Einrichtung. Die Eiliiidung ist auf das dargestellte Auführungaieispiel nicht beschränkt. So können die rohrförmigen Kanäle 6, ; für die >cliratilxnfürniige Führung der wärinetauscheiiden 'Medien aus an sich bekannten Wand an Wand gewickelten Vierkantrohren Bestehen, so claß die zylindrische Wärnietauschfliiche aus einer Fläche der Vierkantrolirc gebildet ist. Di< rohrförmigen handle können aber auch aus Wand an Wand gewickelten Kreisrohren; die ebenfalls an sich bekannt sind, gebildet sein. woh,i die zwischen den Rohren befindlichen Keilflächen durch Ausgießen geglättet sind, so daf5 wieder rein zylindrische Wärtnetauschflächen vorhanden sind.«- as you can see from the drawing, it applies to the inside flowing '\ Zediuin the curved guide effecting the separation of centrifugal forces only over one Part 3 of the entire facility. The decision is based on the example shown not restricted. So the tubular channels 6,; for the> cliratilxnfürniige Management of the heat exchangers' media from per se known wall to wall wrapped Square tubes consist, so the cylindrical heat exchange surface consists of one Surface of the square circle is formed. But the tubular handle can also circular tubes wound from wall to wall; which are also known per se, formed be. wo, i the wedge surfaces between the pipes smoothed by pouring are, so that there are again purely cylindrical exchange surfaces.
