Description

  

  Vorrichtung zum elektrischen Erhitzen von Flüssigkeiten und (Gasen.    Die vorliegende Erfindung     betrifft    eine  Vorrichtung zum     elektrischen    Erhitzen von  Flüssigkeiten und Gasen, und zwar mit zwi  schen zwei ineinandergeschobenen Röhren  eingebautem Widerstande, welehe sich gegen  über den bekannten Heizvorrichtungen dieser  Art durch eine vorteilhafte     Ausführungsform     und bequeme Verwendungsart auszeichnet.  



  Erfindungsgemäss ist in demn Heizrohr  körper durch das eine Ende eine Zuleitung  für das zu erwärmende Medium eingeführt,  die bis nahe an das andere Ende Heran  reichen kann und von der aus das Medium  beim Abfliessen den Heizrohrkörper zuerst  innen und hernach im     Gegenstrome        aussen     bestreicht.  



  Eine beispielsweise Ausführungsform des  Erfindungsgegenstandes ist in der Zeichnung  im Schnitte dargestellt.  



  Ein inneres Rohr<I>a</I> und ein äusseres Rohr<I>b</I>       sind    miteinander unter Bildung eines Hohl  mantelraumes verbunden, der unten geschlos  sen und oben offen, aber durch einen Zapfen     e,     beispielsweise aus Eternit oder Bakelit, ver  schliessbar ist, während das innere Rohr a  unten offen und oben geschlossen ist. In dem    Hohlnmantelraume der beiden Röhren a und b  ist eine     Heizwicklung    d     angeordnet.    Das zu  e rw äi rinende Medium, z. B. Wasser, wird der       Heizvorrichtung        durch    ein Zuleitungsrohr c  zugeführt, das bis nahe an das obere Ende  des Rohres a hineinragt.

   Damit wird bewirkt,  dass keine Dampfansammlung in der     Heiz-          vorrichtung    stattfindet. Beim Weiterströmen  des Wassers in den eingezeichneten Pfeil  richtungen erwärmt es sich sowohl an der  Wandung des Rohres a, als auch an der  Heizfläche des Rohres b, wodurch eine rasche  Erwärmung des durchfliessenden Wassers er  zielt wird. Letzteres verlässt dann die Heiz  rohre     a    und b und das diese umgebende  Mantelrohr<I>f</I> bei     h.     



  Zur     besseren        Wärmeleitung    kann die Heiz  wicklung     d,    die mit Vorteil     bifilar    (wie im       gezeichneten        Ausführungsbeispiel)    gewickelt  und beispielsweise mit Glasperlen isoliert sein  kann,     von    chemisch reinem Quarzsand um  geben sein. Das     111aiiteli-oln,        f'    trägt aussen  vorteilhaft eine     Umhüllung        g    aus einer die  Wärme schlecht leitenden     blasse.     



  Alle drei Röhren     a.,   <I>b</I> und c können als  ein einziges,     zusammengehöriges    Heizelement      anrrgesehen werden. Durch Parallelschalten  mehrerer soleher auf die vorbeschriebene Weise  gebildeten     Heizelemente    in gemeinsamem  Kessel lässt sich die Leistung einer solchen  Heizeinriehtung bestimmen oder regulieren.  Selbstverständlich kann dabei der Wasser  weg auclh umgelehrt erfolgen, und zwar in  den Fällen, wo die kleinste Wärmeausstrahlung  des lKessels verlangt wird und ferner die  hohe Beanspruchung der Heizwicklung nicht       schadet.     



  Ein wesentlicher Vorteil der gezeichneten  Hleizvorriciehtung liegt auch in der raschen  und bequemen Auswechselbarkeit des Doppel-    roteres a, b bei Betriebsstörungen infolge Ver  brennen des Heizwiderstandes.



  Device for electrical heating of liquids and gases. The present invention relates to a device for electrical heating of liquids and gases, with built-in resistors between two nested tubes, which differ from the known heating devices of this type by an advantageous embodiment and convenient Type of use.



  According to the invention, a feed line for the medium to be heated is inserted through one end, which can reach close to the other end and from which the medium first brushes the heating pipe body inside and then outside in countercurrent as it flows out.



  An example embodiment of the subject matter of the invention is shown in section in the drawing.



  An inner tube <I> a </I> and an outer tube <I> b </I> are connected to one another to form a hollow jacket space that is closed at the bottom and open at the top, but by a pin e, for example made of Eternit or Bakelite, ver closable, while the inner tube a is open at the bottom and closed at the top. A heating coil d is arranged in the hollow jacket space of the two tubes a and b. The medium to be expected, e.g. B. water, is fed to the heater through a feed pipe c, which protrudes close to the upper end of the pipe a.

   This ensures that there is no accumulation of steam in the heating device. As the water continues to flow in the directions indicated by the arrow, it heats up both on the wall of the pipe a and on the heating surface of the pipe b, thereby rapidly heating the water flowing through it. The latter then leaves the heating pipes a and b and the jacket pipe <I> f </I> surrounding them at h.



  For better heat conduction, the heating winding d, which can be wound with advantage bifilar (as in the illustrated embodiment) and, for example, insulated with glass beads, be made of chemically pure quartz sand. On the outside, the 111aiiteli-oln, f 'advantageously has a covering g made of a pale that does not conduct heat well.



  All three tubes a., <I> b </I> and c can be viewed as a single heating element that belongs together. The power of such a heating unit can be determined or regulated by connecting several heating elements formed in the manner described above in parallel in a common boiler. Of course, the water can also be reversed, in those cases where the smallest heat radiation from the boiler is required and the high stress on the heating coil does not damage it.



  A major advantage of the heating device shown is the quick and easy interchangeability of the double roters a, b in the event of malfunctions due to burning of the heating resistor.
