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.
