Wartungsfreie Vorrichtung zur Wärmerückgewinnung aus Abwasser 5Maintenance-free device for heat recovery from wastewater 5
Bisher wird beim Duschbad das noch warme Abwasser direkt in die Kanalisation geleitet. Hierbei gehen erhebliche Wärmemengen als Abwärme verloren. Bisher bekannte Wärmetauscher zur Rückgewinnung von Wärme aus Haushaltsabwässern weisen jedoch eine Reihe von konstruktionsbedingten Mangeln auf, die ihrer praktischen Anwendung entgegen stehen. Aufgrund der verwendeten Abwasserspeicher (DE-PS 2517126 C 2, DE-PS 3316704, DE-PS 2825729, DE-PS 4135560 C 2, DE-OS 2952780, DE-OS 3011111, DE-OS 3400759, DE-OS 4402269, DE-OS 4406971), in denen eine gewisse Verwirbelung von warmen und bereits abgekühlten Abwässern unvermeidlich ist, sowie durch Wärmeverluste in den Abwasserleitungen zwischen Abwasserentstehungsort und Wärmetauscher weisen viele Anlagen nur einen geringen Wirkungsgrad auf. Andere Anlagen dieser Art benötigen zu ihrem Betrieb teuere Zusatzeinrichtungen, wie beispielsweise Wärmepumpen oder Sekundärwärmetauscher (DE-OS 3039505, DE-OS 3214357, DE-AS 2304537), oder sind komplex aufgebaut (DE-PS 3119809, DE-OS 3111372, DE-OS 3246586). In diesen sowie weiteren bekannten Wärmetauschern (DE-GM 8203297.1, DD-PS 22920.4, DE-OS 2502351, DE-OS 3717720, DE-GM 8916015.0, DD-PS 236163, DE-OS 3319638, DE-OS 19608404, DE-GM 8600554.5, DD-PS 206511, DE-GM 9309470.1) setzen sich aufgrund geringer Abwasserströmungsgeschwindigkeiten, nichtlaminärer ungleichmäßiger Strömung der Abwässer oder komplex strukturierter Oberflächen während des Betriebes im Abwasser mitgeführte Schmutzpartikel in Speichertanks oder Röhrensystemen der Wärmetauscher ab, was zeitaufwendige Reinigungsarbeiten oder aber komplizierte mechanische Reinigungsvorrichtungen (DE-PS 3119809, DE-PS 2825729, DE-OS 3400759, DE-OS 3406518) erforderlich macht. Aus diesen Gründen ist der Betrieb der genannten Anlagen beim derzeitigen Energiepreisniveau unwirtschaftlich.Up to now, the still warm waste water from a shower has been fed directly into the sewer system. This means that considerable amounts of heat are lost as waste heat. However, heat exchangers known to date for recovering heat from household waste water have a number of design-related defects that prevent them from being used in practice. Due to the waste water storage tanks used (DE-PS 2517126 C 2, DE-PS 3316704, DE-PS 2825729, DE-PS 4135560 C 2, DE-OS 2952780, DE-OS 3011111, DE-OS 3400759, DE-OS 4402269, DE-OS 4406971), in which a certain amount of turbulence between warm and already cooled waste water is unavoidable, as well as due to heat losses in the waste water pipes between the point where the waste water is generated and the heat exchanger, many systems have only a low level of efficiency. Other systems of this type require expensive additional equipment to operate, such as heat pumps or secondary heat exchangers (DE-OS 3039505, DE-OS 3214357, DE-AS 2304537), or have a complex structure (DE-PS 3119809, DE-OS 3111372, DE-OS 3246586). In these and other known heat exchangers (DE-GM 8203297.1, DD-PS 22920.4, DE-OS 2502351, DE-OS 3717720, DE-GM 8916015.0, DD-PS 236163, DE-OS 3319638, DE-OS 19608404, DE-GM 8600554.5, DD-PS 206511, DE-GM 9309470.1), dirt particles carried along in the wastewater settle in storage tanks or pipe systems of the heat exchangers during operation due to low wastewater flow speeds, non-laminar, uneven flow of the wastewater or complex structured surfaces, which requires time-consuming cleaning work or complicated mechanical cleaning devices (DE-PS 3119809, DE-PS 2825729, DE-OS 3400759, DE-OS 3406518). For these reasons, the operation of the above-mentioned plants is uneconomical at the current energy price level.
Der im Schutzanspruch angegebenen Erfindung liegt das Problem zugrunde, die beim Duschen anfallende Restwärme auch bei starkThe invention specified in the protection claim is based on the problem of dissipating the residual heat generated during showering even in strongly
·&phgr;·φ
schwankenden Abwassermengen mit einem hohen Wirkungsgrad mit Hilfe einer wartungsfrei zu betreibenden Anlage zurückzugewinnen. Zur weiteren Erhöhung der Wirtschaftlichkeit soll die Anlage preisgünstig und leicht zu installieren sein. 5to recover fluctuating wastewater volumes with a high degree of efficiency using a maintenance-free system. To further increase economic efficiency, the system should be inexpensive and easy to install. 5
Dieses Problem wird durch die im Schut2anspruch aufgeführten Merkmale gelöst: Glatte Oberflächen der Wärmetauscherelemente, die Vermeidung stehender Abwässer sowie eine gleichmäßige Krümmung der Abwasserrohre im Inneren des Wärmetauschers dienen der Selbstreinigung der Anlage. Durch die Dimensionierung der Abwasserrohre dergestalt, daß sich während des Betriebs stets ein unter Atmosphärendruck stehender Luftspiegel oberhalb des durchfließenden Abwassers befindet, dessen Höhe umgekehrt proportional zum Abwasserdurchsatz ist, kann auch während des Betriebes mit niedrigem Abwasserdurchsatz eine zur Vermeidung einer Sedimentation mitgeführter Schmutzpartikel ausreichende Flußgeschwindigkeit erzielt werden. Außerhalb der Betriebszeit befindet sich keinerlei Abwasser im Inneren des Wärmetauscherelements, was das Wachstum von Mikroorganismen hemmt und ebenfalls der Vermeidung von Schmutzablagerungen dient.This problem is solved by the features listed in the protection claim: smooth surfaces of the heat exchanger elements, the avoidance of stagnant waste water and a uniform curvature of the waste water pipes inside the heat exchanger serve to ensure the system's self-cleaning. By dimensioning the waste water pipes in such a way that during operation there is always an air level at atmospheric pressure above the waste water flowing through, the height of which is inversely proportional to the waste water throughput, a flow rate sufficient to prevent sedimentation of entrained dirt particles can be achieved even during operation with a low waste water throughput. Outside of operating times there is no waste water at all inside the heat exchanger element, which inhibits the growth of microorganisms and also serves to prevent dirt deposits.
Die mit der Erfindung erzielten Vorteile bestehen darin, daß durch die Rückgewinnung eines großen Teils der Abwasser-Restwärme Energieeinsparungen in erheblicher Höhe realisiert werden.The advantages achieved with the invention are that by recovering a large part of the waste water residual heat, considerable energy savings are achieved.
Hierdurch können sowohl C02-Emissionen als auch Heizenergiekosten privater und öffentlicher Anwender beträchtlich reduziert werden. Die Erfindung ist aufgrund ihres einfachen Aufbaus leicht und kostengünstig zu produzieren sowie wartungsfrei zu betreiben, was eine wirtschaftliche Nutzung auch in intensiv genutzten Duscheinrichtungen - z. B. in Schwimmbädern oder Kasernen - ermöglicht, in denen einerseits das größte Energie-Einsparpotential liegt, andererseits aber durch den Betrieb nicht wartungsfreier Anlagen hohe Reinigungs- und Wartungskosten entstünden. Kleiner dimensionierte Ausführungen eignen sich auch zur Installation in privaten Dusch-Naßzellen.This can significantly reduce both C0 2 emissions and heating energy costs for private and public users. Due to its simple design, the invention is easy and inexpensive to produce and maintenance-free, which enables it to be used economically even in intensively used shower facilities - e.g. in swimming pools or barracks - where on the one hand the greatest energy saving potential lies, but on the other hand high cleaning and maintenance costs would arise due to the operation of non-maintenance-free systems. Smaller versions are also suitable for installation in private shower rooms.

Es folgt zunächst die Darstellung der Wärmetauschereinheit für Einzel-Duschanlagen.The following is a description of the heat exchanger unit for individual shower systems .
Bei dieser Form ist die Wärmetauschereinheit vorzugsweise unterhalb der Duschwanne (1) angebracht. Das warme Abwasser strömt durch den Siphon (11) in ein doppelwandiges, spiralförmig gewundenes Rohr, zwischen dessen innerer (3) und äußerer (4) Wand kaltes Wasser im Gegenstrom erwärmt wird. Anschließend verläßt das nun abgekühlte Abwasser die Anlage durch den Auslaß (5) zur Kanalisation. Zur Vermeidung von Wärmeverlusten ist die Rohrschlange mit einem festen, wärmedämmenden Kunststoff umschäumt (6), der zugleich bei der Installation als Auflage für die Duschwanne dient. Der zu- (7) bzw. abführende (8) Frischwasseranschluß wird bei dieser Ausführung an die vorhandene Kaltwasser-Duschinstallation angeschlossen. Fakultativ kann in den abführenden Frischwasseranschluß (8) zwischen Wärmetauscher und Mischbatterie ein wärmeisolierter Tank (10) als Pufferspeicher zur Vermeidung von Temperaturschwankungen bei unterschiedlicher Auslastung des Wärmetauschers eingebaut werden.In this form, the heat exchanger unit is preferably installed below the shower tray (1). The warm waste water flows through the siphon (11) into a double-walled, spiral-shaped pipe, between whose inner (3) and outer (4) walls cold water is heated in countercurrent. The now cooled waste water then leaves the system through the outlet (5) to the sewer system. To avoid heat loss, the pipe coil is covered with a solid, heat-insulating plastic (6), which also serves as a support for the shower tray during installation. In this version, the inlet (7) and outlet (8) fresh water connection is connected to the existing cold water shower installation. Optionally, a heat-insulated tank (10) can be installed in the outlet fresh water connection (8) between the heat exchanger and the mixer tap as a buffer storage to avoid temperature fluctuations when the heat exchanger is used at different levels.
Darstellung der Wärmetauschereinheit für Mehrfach-Duschanlagen: Representation of the heat exchanger unit for multiple shower systems :
Der Aufbau des Wärmetauscherelementes ist im Grundsatz der gleiehe wie bei der vorbeschriebenen Anlage. Aufgrund der räumlich zumeist weniger beengten Verhältnisse bei der Installation kann das Gefälle der Rohrschlange im Inneren des Wärmetauschers größer sein als bei der Wärmetauschereinheit für Einzel-Duschanlagen, was einen höheren Abwasserdurchsatz ermöglicht. Eine besonders vorteilhafte Installationsanordnung ist in Fig. 3a,b dargestellt. Durch Zuführung der Abwasser mehrerer Duschplätze (1) zu einem einzigen Wärmetauscher (13) mittels einer wärmeisolierten Zuleitung (12) kann die gesamte Anlage besonders kostengünstigThe structure of the heat exchanger element is basically the same as in the system described above. Due to the generally less cramped spatial conditions during installation, the gradient of the pipe coil inside the heat exchanger can be greater than in the heat exchanger unit for individual shower systems, which enables a higher wastewater throughput. A particularly advantageous installation arrangement is shown in Fig. 3a,b. By feeding the wastewater from several shower areas (1) to a single heat exchanger (13) using a thermally insulated supply line (12), the entire system can be particularly cost-effective
erstellt werden. Das vorgewärmte Frischwasser kann zur zur Vermeidung
von Wärmeschwankungen bei stark unterschiedlichem
Duschbetrieb wahlweise einem zwischen Wärmetauscher und Mischbatteriein) eingebauten wärmeisolierten Puffer-Speichertank
(Fig. 3a, 10) oder dem Heißwasserbereiter der Duschanlage (Fig. 3b, 14) zugeleitet werden.The preheated fresh water can be used to avoid heat fluctuations in the event of greatly differing
Shower operation optionally a heat-insulated buffer storage tank installed between heat exchanger and mixer tap
(Fig. 3a, 10) or the hot water heater of the shower system (Fig. 3b, 14).
