Abstract

The invention, which would find application in houses and swimming baths as well as in factories, combines in a single unit a temporary reservoir for the dirty waste water from which the heat is to be extracted, a centrifuge to clean it and ensure efficient transfer of heat, and the heat exchange spiral itself. A perforated cone protects the heat exchanger against a fall in the waste water supply, and a safety overflow is provided in case an accumulation of extracted dirt dams up the waste water outlet system. The heat extracted would be used to pre-heat the input to a hot-water supply system or to a heat pump.

Description

Translated fromGerman

Beschreibung Titel : Wärmatauscher mit Schmutzabscheider zur Wärmeenergie@usnützungdes Abwassers.Description Title: Heat exchanger with dirt separator for thermal energy utilizationof sewage.

Anwendungsgebiet : Zur Wärmeenergieausnützung des Abwassers in Wohnhäusern,Schwimmbädern und Industriewerken etc. in Verbindung mit Brauchwasserbereitern undWärmepumpenanlagen.Area of application: For the utilization of heat energy from wastewater in residential buildings,Swimming pools and industrial plants etc. in connection with water heaters andHeat pump systems.

Zweck : Die Vorrichtung nützt die Wärmeenergie aus dem Abwasser (z.B. Duschabwasser in Schwimmbädern, Abwasser aus Waschmaschinen und Ge-Schirrspülma&chinenetc.) aus.Purpose: The device uses the thermal energy from the wastewater (e.g.B. Shower wastewater in swimming pools, wastewater from washing machines and dishwashersetc.).

Um eine Verschmutzung des Rippenronrwarmetauschers möglichst zu vermeiden,ist er mit einem Zentrifugalabscheider kombiniert. To avoid contamination of the Rippenron heat exchanger as much as possible,it is combined with a centrifugal separator.

Stand der Technik: Die bekannt-en Wärmetauschanlagen zur energetischenAusnützung des Abwassers (z.B. In vollelekriscn beheizten Hallenbadern) bestenenaus getrennten Wärmetauschern und Abscheidern.State of the art: The known heat exchange systems for energeticUtilization of wastewater (e.g. in fully electrically heated indoor swimming pools)from separate heat exchangers and separators.

Aufgaben : Der Konstruktion liegen die Aufgaben zugrunde : - den Rippenrohrwärmetauschervor Verschmutzung durch Schwemmstoffe zu schützen und damit ständig einen gutenWärmeübergang zu ernalten.Tasks: The design is based on the tasks: - The finned tube heat exchangerto protect against pollution by floating debris and thus constantly a good oneTo avoid heat transfer.

- ein Puffergefeib im Abwassersystem zu bilden, um das Abwasser möglichstweit energetisch ausnützen zu können. - to form a buffer structure in the sewage system to avoid wastewaterto be able to use far energetically.

- Trinkwasser wor Eintritt in den Brauchwassererhitzer vorzuwärmenoder Grund-, Fluß- oder Erunnenwasser (ggf. auch Sole) vor Eintritt in den Verdampfereiner Wärmepumpe aufzuwärmen oder bei Verwendung des Rippenrohrwärmetauschers alsDirektverdampfer das Kältemittel zum Verdampfen und damit zur Wärmeenergieaufnahmezu bringen. - Preheat drinking water wor entering the domestic water heateror ground, river or Erunnen water (possibly also brine) before entering the evaporatora heat pump or when using the finned tube heat exchanger asDirect evaporator the refrigerant for evaporation and thus for absorbing heat energybring to.

Lösungen: Die Aufgaben wurden dadurch gelöst, daß der Wärmetauscherim Zentrum des Abscheiders (Reinseite) angeordnet wurde und zusätzlich durch Abweisfläcnebei geringem Abwasserzulauf und damit verbundener geringerer Zentrifugalwirkunggeschützt wird.Solutions: The tasks were solved in that the heat exchangerin the center of the separator (clean side) and additionally through Abweisfläcnewith low wastewater inflow and the associated lower centrifugal effectis protected.

Um bei Unterlassung einer Abschlämmung des Grobschmutzes keinen Rückstauin der Abwasserleitung zu erhalten, wurde das System mit einem Sicherheitsüberlaufversehen. So that there is no backwater if the coarse dirt is not blown downTo get into the sewer, the system was equipped with a safety overflowMistake.

Erzielbare Vorteile: Mit der Vorrichtung können folgende Vorteileerzielt werden: - wärmeenergetische Ausnützung des Abwassers durch eine Kompakteinheit- schnellere Installation als getrennte Einheiten - die Warmetauscher - Abscheiderkombinationdient gleichzeitig als Pufferbehälter bzw.Achievable advantages: With the device, the following advantagesthe following can be achieved: - Use of the wastewater for thermal energy through a compact unit- faster installation than separate units - the heat exchanger - separator combinationalso serves as a buffer tank or
