Description

Der Erfindungsgegenstand gehört zum technischen Gebiet der Energierückgewinnung durch Abgaswärme. Abgaswärmetauscher dienen der Rückgewinnung von Energie in Form von Abwärme der beim Heizvorgang entstehenden Abgase, die bei häuslichen Verbrennungsanlagen, wie z. B. Öfen oder Kaminen, entstehen. Abgaswärmetauscher sind Bestandteile von Zentralheizungen von Wohnhäusern, Industrieanlagen oder von anderweitig genutzten gewerblichen Immobilien. Sie dienen der Rückgewinnung von warmer Wasser und werden als Wasserwärmetauscher bezeichnet. Durch die Nutzung der Wärmeenergie in den Abgasen wird das durchlaufende Wasser erhitzt und in den Heizkessel zur weiteren Verwendung geleitet, ohne zusätzliche Energie zur Erhitzung des Wassers aufbringen zu müssen.The subject invention belongs to the technical field of energy recovery by exhaust heat. Exhaust gas heat exchangers are used to recover energy in the form of waste heat from the exhaust gases produced during the heating process, which in domestic incinerators, such. As stoves or fireplaces arise. Flue gas heat exchangers are components of central heating of residential buildings, industrial plants or other commercial real estate. They are used for the recovery of warm water and are referred to as water heat exchangers. By utilizing the heat energy in the exhaust gases, the water passing through them is heated and sent to the boiler for further use, without having to expend additional energy to heat the water.

Derzeitig auf dem Markt erhältliche Wasserwärmetauscher bestehen aus Heizspiralen, durch die das Wasser geleitet wird. Diese Heizspiralen liegen am Abgasrohr entweder innen oder außen.Currently available on the market water heat exchangers consist of heating coils, through which the water is passed. These heating coils lie on the exhaust pipe either inside or outside.

Die Verwendung von Heizspiralen, die außerhalb des Abgasrohres liegen, bringt einen enormen Energieverlust mit sich, da sie nur einen indirekten Kontakt zum Abgasrohr haben. Die innen liegenden Heizspiralen, welche sich innerhalb des Abgasohrs befinden, durch die die Abgase strömen, haben zusätzlich einen höheren Wartungsaufwand. Andere Wasserwärmetauscher, welche nicht funktionell durch Heizspiralen funktionieren, verfügen über eine an der Außenwand des Abgasrohres befindliche zweite Ummantelung die als Wasserkammer genutzt wird. Dieses Einkammersystem, hat den Nachteil, dass das dort durchfließende Wasser aufgrund des kurzen Weges zwischen Wassereingang und Wasserausgang nicht ausreichend erhitzt wird.The use of heating coils, which lie outside the exhaust pipe, brings a huge loss of energy, since they have only an indirect contact with the exhaust pipe. The internal heating coils, which are located within the exhaust pipe through which the exhaust gases flow, also have a higher maintenance. Other water heat exchangers, which do not function functionally by heating coils, have a second jacket located on the outer wall of the exhaust pipe and used as a water chamber. This one-chamber system has the disadvantage that the water flowing through it is not sufficiently heated due to the short path between the water inlet and the water outlet.

Die anzumeldende Erfindung löst die vorgenannten Probleme durch die Verwendung eines Mehrkammersystems. Hierdurch wird es ermöglicht, dass das Wasser einen längeren Weg zurücklegt, was dazu führt, dass höhere Temperaturen erreicht werden. Die anzumeldende Erfindung besteht aus einem Innenrohr als Durchströmsystem für die Abgase, welches von außen durch das Mehrkammersystem umgeben ist, die aus mehreren einzelnen Kammern (7) besteht. Die einzelnen Kammern (7) bestehen aus einem Blechmantel (9) und zwei Kappen (8) oben und unten. Nachdem das Wasser durch den Wassereingang (1) in die erste Kammer eingelassen wird, fließt es bis zum Ende der senkrecht angeordneten Kammer, an deren Ende sich eine Öffnung (10) zur nächstliegenden Kammer befindet. Das Wasser fließt sodann durch jede einzelne Kammer, welche jeweils an ihren oberen und unteren Enden mit Öffnungen (10) zueinander versehen sind. Nach dem sich das Wasser um das gesamte Rohr herumbewegt hat, fließt es sodann in die neben dem Wassereingang liegende Kammer, in der sich gleichzeitig der Wasserausgang befindet. Ein Rückfluss in die Wassereingangskammer ist aufgrund der zueinander öffnungslosen Kammern nicht möglich. Das durchströmende Wasser legt damit einen insgesamt langen Weg zurück, so dass eine optimale Erhitzung des durchfließenden Wassers erreicht wird.The invention to be addressed solves the aforementioned problems by using a multi-chamber system. This will allow the water to travel a longer distance, resulting in higher temperatures being achieved. The invention to be registered consists of an inner tube as a Durchströmsystem for the exhaust gases, which is surrounded from the outside by the multi-chamber system consisting of several individual chambers ( 7 ) consists. The individual chambers ( 7 ) consist of a metal jacket ( 9 ) and two caps ( 8th ) above and below. After the water through the water inlet ( 1 ) is introduced into the first chamber, it flows to the end of the vertically arranged chamber, at the end of which an opening ( 10 ) to the nearest chamber. The water then flows through each individual chamber, which at their upper and lower ends with openings ( 10 ) are provided to each other. After the water has moved around the entire pipe, it then flows into the next to the water inlet chamber, in which the same time the water outlet. A backflow into the water inlet chamber is not possible due to the mutually open-ended chambers. The water flowing through it thus covers an altogether long path, so that an optimal heating of the water flowing through is achieved.

Ferner ist der Wasserwärmetauscher mit zusätzlichen Öffnungen (11), welche als Einlass für ein innen verlegtes Kühlrohr (3) (4) dienen, versehen. Diese Öffnungen erfolgen an den Kappen (8) der einzelnen Kammern.Furthermore, the water heat exchanger with additional openings ( 11 ), which as inlet for a internally installed cooling tube ( 3 ) ( 4 ) serve provided. These openings are made on the caps ( 8th ) of the individual chambers.

In den Kammern führt ein zusätzliches Rohr (3) (4) durch die Kappe über dem Wassereingang durch das Kammersystem bis zur Kappe über dem Wasserausgang, welches mit Frischwasser versorgt werden kann, um das Mehrkammersystem bei Überhitzung ausreichend zu kühlen.In the chambers an additional pipe ( 3 ) ( 4 ) through the cap above the water inlet through the chamber system to the cap above the water outlet, which can be supplied with fresh water to cool the multi-chamber system in case of overheating sufficient.

Die Vorteile des Mehrkammersystems liegen einerseits in dem geringeren Wartungsaufwand, welcher insbesondere im Gegensatz zu dem bereits genannten Heizspiralensystem bestehen. Auch eine zusätzliche Reinigung innerhalb des Abgasrohres (5) von innen ist völlig obsolet. Im Gegensatz zu üblichen Einkammersystemen kann eine höhere Temperatur erreicht werden. Aufgrund der sowohl leichteren Wartung als auch höher erreichten Temperatur des Wassers, können die Kosten für den Betrieb des Energierückgewinnungssystems im Gegensatz zu anderen Systemen mit gleicher Intention erheblich gesenkt werden.The advantages of the multi-chamber system are on the one hand in the lower maintenance costs, which exist in particular in contrast to the already mentioned Heizspiralensystem. Also an additional cleaning within the exhaust pipe ( 5 ) from the inside is completely obsolete. In contrast to conventional single-chamber systems, a higher temperature can be achieved. Due to both easier maintenance and higher temperature of the water, the cost of operating the energy recovery system, unlike other systems with the same intention can be significantly reduced.
