Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die beiliegende Zeichnung stellt einen Apparat dar, welcher sowohl als Speisewasservorwärmer für Dampfkessel und andere Zwecke, wie auch als Kühlapparat benutzt werden kann.The accompanying drawing shows an apparatus that can be used both as a feedwater preheater for steam boilers and other purposes, as well as can be used as a cooling device.
α und b sind zwei verticale Kessel, welche fast gleiche Höhe, aber verschiedene Durchmesser haben. Der Durchmesser von b ist ungefähr viermal so grofs als der von a. In dem kleineren Kessel befinden sich zwei verticale Röhren c und d aus Kupfer oder Bronze, welche oben durch das Querrohr d2 verbunden sind. Das untere Ende des Rohres c mündet in die Kammer e mit dem Rohr/, durch welches das Wasser dem Apparat zugeführt wird. Das zweite Rohr d mündet unten in die andere Kammer e2 des Gefäfses a, welche mit dem unteren Theil des gröfseren Kessels b in Verbindung steht. In letzterem befinden sich Röhren g aus Kupfer oder Bronze, welche" in concentrischen Kreisen angeordnet und oben in einer Platte h, unten in einer Platte i befestigt sind. Die Röhren münden oben in den Raum k, welcher mit geneigten, oben geschlossenen Röhren / versehen ist. An k schliefst sich oben das Rohr m an, durch welches dem Apparat der verbrauchte Dampf einer Dampfmaschine zugeführt wird. Die unteren Enden der Röhren stehen durch den Kanal p mit dem kleineren Kessel a in Communication. Der durch m in den Raum k und die Röhren / eintretende Dampf geht, also durch die Röhren g und den Kanal p nach dem kleineren Kessel α und entweicht durch das Rohr β4. Das Condensationswasser sammelt sich in dem Raum a2 und kann von Zeit zu Zeit durch das Ventil a3 abgelassen werden· Das zu reinigende kalte Wasser tritt nahe am Boden des kleinen Kessels α durch das Rohr/ ein und strömt durch die Röhren c und d nach dem gröfseren Kessel b, an dessen oberem Ende es durch das Rohr q den Apparat verläfst. Da der Dampf und das Wasser in entgegengesetzten Richtungen durch den Apparat circuliren, so wird letzteres allmälig erwärmt und schliefslich durch die Röhren / auf die Temperatur des frisch eintretenden Dampfes gebracht. Die ausgeschiedenen Kalksalze fallen in dem Behälter b nieder und sammeln sich in dem Raum b1, von wo sie durch das Ventil b3 abgelassen werden können. Anstatt des gebrauchten Dampfes kann auch frisch vom Kessel kommender Dampf verwendet werden, wenn man dem Speisewasser eine höhere Temperatur geben will, um die Fällung der im Wasser enthaltenen Unreinigkeiten zu beschleunigen. α and b are two vertical bowls, almost the same height, but different diameters. The diameter of b is about four times that of a. In the smaller boiler there are two vertical tubes c and d made of copper or bronze, which are connected at the top by the cross tube d 2 . The lower end of the tube c opens into the chamber e with the tube / through which the water is fed to the apparatus. The second tube d opens at the bottom into the other chamber e 2 of the vessel a, which communicates with the lower part of the larger vessel b . In the latter there are tubes g made of copper or bronze, which are "arranged in concentric circles and fastened at the top in a plate h and at the bottom in a plate i . The tubes open at the top into the space k, which is provided with inclined tubes / closed at the top." At the top of k is the pipe m , through which the used steam of a steam engine is fed to the apparatus. The lower ends of the pipes are in communication with the smaller boiler a through the channel p . The one through m into the space k and the tubes / incoming steam goes through the tubes g and the channel p to the smaller boiler α and escapes through the tube β 4. The condensation water collects in the space a 2 and can be drained from time to time through the valve a 3 The cold water to be purified enters close to the bottom of the small boiler α through the pipe / and flows through the pipes c and d to the larger boiler b, at the upper end of which it passes through the pipe q to the apparatus expires. As the steam and the water circulate through the apparatus in opposite directions, the latter is gradually heated and finally brought through the tubes / to the temperature of the freshly entering steam. The precipitated calcium salts fall down in the container b and collect in the space b 1 , from where they can be drained through the valve b 3. Instead of the used steam, steam freshly coming from the boiler can also be used if you want to give the feed water a higher temperature in order to accelerate the precipitation of the impurities contained in the water.
Soll die beschriebene Einrichtung als Kühlapparat benutzt werden, so läfst man die zu kühlende Flüssigkeit in der für das Speisewasser beschriebenen Weise circuliren, und das kalte Wasser oder die kühlende Flüssigkeit in der für den Dampf angegebenen Richtung.If the device described is to be used as a cooling device, it is closed circulate the cooling liquid in the manner described for the feed water, and the cold one Water or the cooling liquid in the direction indicated for the steam.
