Description
Einrichtung zum Beseitigen von Krusten in Wärmeaustauschapparaten und Rohrleitungen durch elastische Formänderungen Die Krustenbildung in Wärmeaustauschapparaten und Rohrleitungen bei Behandlung von Flüssigkeiten, die beim Erwärmen, Verdampfen, Abkühlen oder bei Fortleitung Krusten abscheiden, bereitet erhebliche Betriebsschwierigkeiten, sei es, daß die Wärmeübertragung eingeschränkt oder die Liefermenge der Einrichtungen durch Querschnittsverengung gemindert wird.Device for removing crusts in heat exchange apparatus and pipelines due to elastic changes in shape. The formation of crusts in heat exchange apparatus and pipelines for the treatment of liquids that occur during heating, evaporation, Cooling down or depositing crusts when carried on creates considerable operational difficulties, be it that the heat transfer is restricted or the delivery volume of the facilities is reduced by narrowing the cross-section.
Zur Bekämpfung dieser Übelstände sind mancherlei 'Maßnahmen bekannt. Die Heizelemente sind z. B. baulich so ausgebildet, daß ihre Flächen bei den ihrer jeweiligen Aufgabe entsprechenden Temperaturschwankungen elastische Formänderungen erleiden, durch welche spröde Krusten mehr oder weniger abgesprengt werden. Auch suchte man solche Heizflächen nach oder vor dem eigentlichen Arbeitsvorgang oder nach einer längeren Betriebszeit durch sogenanntes Abschrecken, so gut es- ging, zu reinigen. Beispiele solcher. Bauformen von Heizflächen sind Rohrschlangen und spiralig aufgerollte, in der Abwicklung rechteckige Hohlkörper von geringer Dicke und großer Länge.Various measures are known to combat these evils. The heating elements are z. B. structurally designed so that their surfaces in their temperature fluctuations corresponding to the respective task, elastic changes in shape suffer through which brittle crusts are more or less blasted off. Even If you were looking for such heating surfaces after or before the actual work process or after a longer period of operation by so-called quenching, as good as possible, to clean. Examples of such. Types of heating surfaces are pipe coils and Spirally rolled up, in the development rectangular hollow body of small thickness and great length.
Ein anderer Weg, die Krustenbildung zu verringern, ist die Steigerung der Relativbewegung der Wärmeaustauschfläche gegen-Üb,--r den vorbeiströmenden 'Mitteln etwa durch Drehen, besonders wenn die Strömungsgesch«#indigkeiten klein sind.Another way to reduce crust formation is to increase it the relative movement of the heat exchange surface in relation to the means flowing past by turning, for example, especially when the flow velocities are small.
Bekannt sind ferner elektrische Methoden zur Bekämpfung der Krustenbildung wie 1 auch rein mechanische Beseitigung etwaigen Ansatzes durch Bürsten und Schaberwerke mit Hand- oder Maschinenantrieb. Der Vollständigkeit wegen sei auch die chemische Bekämpfung der Krusten erwähnt, bei welchen chemische Veränderung zugunsten der Verineidung oder Beschränkung des Ansatzes im jeweiligen Mittel angewendet wird.Also known are electrical methods to combat scale formation such as 1 purely mechanical removal possible approach through brushes and scraper works with manual or machine drive. For the sake of completeness, the chemical control of the crusts should also be mentioned, in which chemical change is used in the respective agent in order to avoid or limit the approach.
Die Erfindung bezieht sich auf federnde, elastische Heizwände bzw. Wärmeaustauschflächen, gegebenenfalls solche Flächen aus biegsamen Baustoff, und auf Wandungen der Rohrleitungen für krustenbildende Flüssigkeiten. In bekannter. «"eise werden dem Wärme aufnehmenden, dem Wärme abgebenden Mittel während des Betriebes ständig; gegebenenfalls auch beiden 'Mitteln. Druckwellen erteilt, die in* Perioden, welche der Verkriistungsgeschwindigkeit angepaßt werden. willkürlich und in ausreichender Stärke Formänderungen der elastischen oder biegsamen Wärmeaustauschflächen hervorrufen. Diese Formänderungen sprengen die Krusten ab. Rohrwände können von einem Hilfsstoff in einem Druckraum umgeben werden, in welchem man diese Druckwellen erzeugt.The invention relates to resilient, elastic heating walls or Heat exchange surfaces, if necessary such surfaces made of flexible building material, and on the walls of the pipelines for crust-forming liquids. In well-known. The heat absorbing, the heat releasing agent becomes "" ice during operation constant; possibly also both 'means. Pressure waves issued in * periods, which are adapted to the rate of crystallization. arbitrarily and in sufficient Strong changes in the shape of the elastic or flexible heat exchange surfaces. These changes in shape break off the crusts. Pipe walls can be made of an auxiliary material be surrounded in a pressure space in which these pressure waves are generated.
Die Erfindung besteht darin. daß die elastischen oder biegsamen Wärmeaustauschflächeii mehrere Ruhelagen haben, z. B. von einem Standpunkte aus gesehen hohle oder erhabene Form. Bei dem durch Druckwechsel hervorgerufenen Übergang von der einen Form in die andere durchschreitet die Heizfliiche oder Kühlfläche einen faltenreichen Zustand, der zum Absprengen der Krusten führt. Die Ausführungsformen der Erfindung sind nach Bauart und Baustoff der jeweiligen industriellen Aufgabe entsprechend vielgestaltig. Zwei schematische Beispiele zeigt die Zeichnung, und zwar: Fig. i und 3 eine Rohrleitung und Fig. a und 4 einen Verdampfer.The invention consists in this. that the elastic or flexible heat exchange surfaces have several rest positions, e.g. B. hollow or raised when viewed from one point of view Shape. The transition from one form to the other passes through the heating surface or Cooling surface a Wrinkled condition that leads to the cracking of the crusts. The embodiments of the invention depend on the design and building material of the respective industrial task accordingly diverse. Two schematic examples are shown in the drawing, and namely: Fig. i and 3 a pipeline and Fig. a and 4 an evaporator.
In Fig. i ist a die elastische oder biegsame Wandung einer Rohrleitung in der einen Ruhelage, die von einer zweiten Wandung b umeben ist. Im Zwischenraum c, der bei d ständig mit einer Vorrichtung in Verbindung steht, wird durch diese Vorrichtung in beliebigen, der Verkrustungsgeschwindigkeit angepaßten Perioden ein Druckwechsel erzeugt, der die Rohrwandung a vorübergehend in die strichpunktierte zweite Ruhelage überführt, wobei ein faltenreicher Zwischenzustand der Wandung zu durchschreiten ist und durch diese Formänderung das Absprengen der Krusten hervorgerufen wird.In Fig. I, a is the elastic or flexible wall of a pipeline in the one rest position which is surrounded by a second wall b. In the space c, which is constantly connected to a device at d, a pressure change is generated by this device in any period adapted to the incrustation rate, which temporarily transfers the pipe wall a to the second idle position, with a fold-rich intermediate state of the wall to pass through and this change in shape causes the crusts to burst off.
Fig. 2 stellt die Anwendung des Erfindungsgedankens bei einem Verdampfer oder einem Kristallisator dar. i ist die biegsame oder elastische Wärmeaustauschfläche in der einen Ruhelage. Zwischen i und einer festen Wand e fließt das Heiz- oder Kühlmittel, das bei in zugeführt und bei ia abgeleitet wird. Bei g ist eine Vorrichtung angeschlossen, die imRaum :" zwischen i und e periodischDruck Wechsel hervorruft. Jeder Druckwechsel treibt die Wärmeaustauschfläche aus der gezeichneten Ruhelage in die strichpunktierte zweite Ruhelage, wobei eine faltenreiche Form der Wärmeaustauschfläche zu durchschreiten ist . und die Krusten abgesprengt «erden. Die abgesprengten Krusten werden bei k abgeführt, während Dämpfe bei l entweichen können.Fig. 2 shows the application of the inventive concept to an evaporator or a crystallizer. i is the flexible or elastic heat exchange surface in one rest position. The heating or flows between i and a solid wall e Coolant that is fed in at in and drained off at ia. At g is a device connected, which in the space: "periodically causes pressure changes between i and e. Every change in pressure drives the heat exchange surface out of the drawn rest position in the dot-dashed second rest position, with a wrinkled shape of the heat exchange surface is to be traversed. and the crusts blasted off. The blasted off crusts are discharged at k, while vapors can escape at l.
Die Umformungen der Wärmeaustauschfläche können anstatt durch gleichmäßig verteilten Druck auch durch Angriff an Einzelpunkten durch rein mechänische oder elektromagnetische Vorrichtungen hervorgerufen werden.The deformations of the heat exchange surface can instead of through evenly distributed pressure also by attacking individual points by purely mechanical or electromagnetic devices.
Die nach dem Erfindungsgedanken erfolgende Reinhaltung der Wärmeaustauschflächen kann durch Bürsten- und Schaberwerke unterstützt werden.Keeping the heat exchange surfaces clean according to the concept of the invention can be supported by brushes and scrapers.
Die Perioden der Formänderungen können zu hoher Wechselzahl gesteigert werden, so daß die Säuberung der Wärmeaustauschfläche beim Zerbröckeln der Krusten durch Abschütteln gefördert wird.The periods of shape changes can be increased to a high number of changes so that the cleaning of the heat exchange surface when the crusts crumble is promoted by shaking off.
