Die Erfindung betrifft eine Wärmeaustauschvorrichtung, bei welcher das unten eintretende Heizmittel in bekannter Weise einer in den oberen Flüssigkeitsschichten befindliehen Kammer zugeführt und aus dieser durch Röhren im Gegenstrom zu der aufsteigenden, zu erhitzenden Flüssigkeit nachThe invention relates to a heat exchange device in which the bottom entering Heating means located in a known manner one in the upper liquid layers Chamber and from this through tubes in countercurrent to the ascending, liquid to be heated

ίο Übelstand, daß eine Abkühlung des Heizmittels stattfindet, bevor dasselbe in die obere Kammer, also in die heißesten Flüssigkeitsschichten gelangt. Bei einer Warmwasserbereitungsanlage mit Maschinenabdampf z. B.ίο Illness that a cooling of the heating medium takes place before it gets into the upper chamber, i.e. into the hottest layers of liquid. With a water heating system with machine exhaust e.g. B.
bedeutet jede Erhöhung der Abdampftemperatur über die Heißwasserabflußtemperatur einen Mehrdampf- also Mehrkohlenverbrauch; diese Erhöhung ist durch die stattfindende Abkühlung erforderlich und wird um so größer, je höher die Vorrichtung und je kälter die einströmende Flüssigkeit ist.means any increase in the evaporation temperature above the hot water drainage temperature a multi-steam, i.e. multi-coal consumption; this increase is due to the taking place Cooling is required and becomes greater the higher the device and the colder the inflowing liquid.
Die vorliegende Neuerung besteht darin, daß zur Behebung dieses Ubelstandes das das Heizmittel in die obere Kammer b führende Rohr ummantelt ist, ein Teil des Heizmittels in den Mantelraum geleitet und dadurch eine reine Gegenstromwirkung der \Aorrichtung erreicht wird.The present innovation is that to remedy this Ubelstandes the heating means in the upper chamber b conducting pipe is coated, a part of the heating medium passed into the shell space, thereby a pure counterflow effect of the \ A orrichtung is achieved.
Fig. ι zeigt die neue Vorrichtung als Vorwärmer im Längsschnitt, Fig. 2 im Querschnitt. Der Heizdampf tritt bei α durch den bekannten, als Wasserabscheider wirkenden Verteilungstopf in ein Rohr d und steigt in die warmen Wasserschichten, ohne zu heizen, da das Rohr d von dem Rohre e umgeben ist und zwischen beiden eine Dampfschicht sich befindet. Der Dampf gelangt in die Kammer b, trifft dort zuerst auf eine Heizfläche, wird auf die Röhren f verteilt, durchströmt sie im Gegenstrom zum aufsteigenden Wasser und verläßt durch den Sammelraum m und den Verteilungstopf bei c die Vorrichtung. Das kalte Wasser tritt bei h ein, wird während des Aufsteigens durch den entgegenströmenden Dampf erwärmt und verläßt die Vorrichtung bei i. Fig. Ι shows the new device as a preheater in longitudinal section, Fig. 2 in cross section. The heating steam passes at α through the well-known distribution pot acting as a water separator into a pipe d and rises into the warm water layers without heating, since the pipe d is surrounded by the pipe e and there is a layer of steam between the two. The steam enters chamber b, where it first encounters a heating surface, is distributed over tubes f , flows through them in countercurrent to the rising water and leaves the device through collecting space m and the distribution pot at c. The cold water enters at h , is heated by the steam flowing in the opposite direction as it rises, and leaves the device at i.
Die in den Raum zwischen den Röhren d und e durch Öffnungen g eintretende Dampfmenge, welche den zuströmenden Dampf gegen vorzeitige Abkühlung durch das Wasser zu schützen hat, überträgt ebenfalls durch Rohr e Wärme im Gegenstrom auf das aufsteigende Wasser. Die hauptsächliche Heizwirkung fällt jedoch den Röhren f zu. Durch die Öffnungen g wird zugleich das Niederschlagwasser heruntergeleitet.The amount of steam entering the space between tubes d and e through openings g , which has to protect the inflowing steam against premature cooling by the water, also transfers heat in countercurrent through tube e to the rising water. The main heating effect, however, falls on the tubes f . The rainwater is led down through the openings g at the same time.
Durch genügend weite Heizröhren/können gegebenenfalls noch Röhren hindurchgeführt werden, die von der aufsteigenden Flüssigkeit mit durchflossen werden, so daß der die Röhren f durchströmende Dampf nach innen und außen heizt.If necessary, tubes through which the rising liquid also flows can be passed through sufficiently wide heating tubes / so that the steam flowing through the tubes f heats inwards and outwards.
