KAISERLICHESIMPERIAL
PATENTAMTPATENT OFFICE
Die vorliegende Neuerung bezieht sich auf eine Abänderung der Gestalt der von innen geheizten, oben und unten flüssigkeitsdicht eingesetzten Heizrohre, welche bei dem Oberflächenverdampfer des Haupt-Patentes benutzt werden, sowie der Richtung, in welcher die letzteren, von dem zur Beheizung derselben benutzten Dampf durchflossen werden.The present innovation relates to a change in the shape of the inside heated, liquid-tight inserted heating pipes at the top and bottom, which are used in the surface evaporator of the main patent and the direction in which the the latter, are traversed by the steam used to heat the same.
An Stelle der Rohre von gleichmäfsigem Querschnitt, welche in dem Haupt-Patent angegeben sind, können auch konische Rohre a verwendet werden, wie dieses aus den Querschnittsfiguren ι und ι a und der Grundrifsfigur ib zu ersehen ist. Die um die Rohre a in dem Boden d des zur Einführung der 'zu' verdampfenden Flüssigkeit dienenden Raumes b freigelassenen Oeffnungen ο können hierbei hochgehende Ränder o" besitzen, wie dieses in der Fig. 1 angedeutet.Instead of the tubes of uniform cross-section, which are specified in the main patent, conical tubes a can also be used, as can be seen from the cross-sectional figures ι and ι a and the basic figure ib. The openings ο left free around the tubes a in the bottom d of the space b serving for the introduction of the liquid to be evaporated can have raised edges o ″, as indicated in FIG.
Für diejenigen Fälle, in welchen es vortheilhafter erscheint, ohne den hochgehenden Rand o" zu arbeiten, wird derselbe bis in die Ebene der Grundplatte d gesenkt,' so dafs nur unterhalb derselben der Stutzen o1 zur Führung der Flüssigkeit in Mantelform auf die Aufsenwandung der Rohre verbleibt, wie dieses in der Fig. ia angegeben ist.For those cases in which it seems more advantageous to work without the raised edge o " , it is lowered into the plane of the base plate d, so that only below it the nozzle o 1 for guiding the liquid in the form of a jacket onto the outer wall of the Pipes remain, as indicated in Fig. Ia.
Die konische Form der Rohre α hat die Wirkung, die Beschleunigung, welche die Schwere auf die Abwärtsbewegung der Flüssigkeit ausübt, im Verhältnifs der Zunahme des Rohrumfanges zu mäfsigen und die Stärke der beheizten FlUssigkeitsschicht der seitlichen Ausdehnung entsprechend zu verringern. Die mit zunehmender Dichte der beheizten Flüssigkeit abnehmende Verdampfung derselben wird hierbei durch die Vermehrung der Heizfläche infolge der nach unten stetig zunehmenden Oberfläche der konischen Rohre wieder erhöht, so dafs bei richtiger Bemessung der Konicität in jedem Querschnitt des Verdampfers gleiche Mengen Dampf entwickelt werden können, also die Verdampfung auf der ganzen Längenausdehnung der Rohre eine gleichmäfsige wird.The conical shape of the tubes α has the effect of moderating the acceleration which gravity exerts on the downward movement of the liquid in proportion to the increase in the circumference of the tube and of reducing the thickness of the heated liquid layer corresponding to the lateral expansion. The evaporation of the same, which decreases with the increasing density of the heated liquid, is increased again by the increase in the heating surface as a result of the downwardly increasing surface of the conical tubes, so that if the conicity is correctly dimensioned, equal amounts of steam can be developed in every cross-section of the evaporator the evaporation becomes uniform over the entire length of the pipes.
Die Heizrohre α können auch derart ausgeführt werden, dafs dieselben auf einen Theil ihrer Längenausdehnung den gleichen und auf einen Theil (gewöhnlich den oberen Theil) derselben einen in der Richtung des Flüssigkeitsstromes zunehmenden Querschnitt erhalten.The heating tubes α can also be constructed in such a way that they have the same cross-section over part of their length and a part (usually the upper part) of which they have a cross-section increasing in the direction of the flow of liquid.
In den Fig. 2 und 2 a und dem Grundrifs Fig. 2 b ist der Fall vorgesehen, dafs der Heizdampf nicht, wie bei dem Haupt-Patent dargestellt wurde, von unten, sondern von oben in die Rohre α eingeleitet wird. Dabei findet Gleichströmung von Flüssigkeit und Dampf in dem Verdampfer statt.In FIGS. 2 and 2a and the outline of FIG. 2b, the case is provided that the heating steam is introduced into the tubes α not from below, as was shown in the main patent, but from above. In this case, the liquid and vapor flow in parallel in the evaporator.
