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

Beschreibung Titel : Wärmatauscher mit Schmutzabscheider zur Wärmeenergie@usnützung des Abwassers.Description Title: Heat exchanger with dirt separator for thermal energy utilization of sewage.

Anwendungsgebiet : Zur Wärmeenergieausnützung des Abwassers in Wohnhäusern, Schwimmbädern und Industriewerken etc. in Verbindung mit Brauchwasserbereitern und Wärmepumpenanlagen.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 and Heat pump systems.

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

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 energetischen Ausnützung des Abwassers (z.B. In vollelekriscn beheizten Hallenbadern) bestenen aus getrennten Wärmetauschern und Abscheidern.State of the art: The known heat exchange systems for energetic Utilization 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 Rippenrohrwärmetauscher vor Verschmutzung durch Schwemmstoffe zu schützen und damit ständig einen guten Wärmeübergang zu ernalten.Tasks: The design is based on the tasks: - The finned tube heat exchanger to protect against pollution by floating debris and thus constantly a good one To avoid heat transfer.

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

- Trinkwasser wor Eintritt in den Brauchwassererhitzer vorzuwärmen oder Grund-, Fluß- oder Erunnenwasser (ggf. auch Sole) vor Eintritt in den Verdampfer einer Wärmepumpe aufzuwärmen oder bei Verwendung des Rippenrohrwärmetauschers als Direktverdampfer das Kältemittel zum Verdampfen und damit zur Wärmeenergieaufnahme zu bringen. - Preheat drinking water wor entering the domestic water heater or ground, river or Erunnen water (possibly also brine) before entering the evaporator a heat pump or when using the finned tube heat exchanger as Direct evaporator the refrigerant for evaporation and thus for absorbing heat energy bring to.

Lösungen: Die Aufgaben wurden dadurch gelöst, daß der Wärmetauscher im Zentrum des Abscheiders (Reinseite) angeordnet wurde und zusätzlich durch Abweisfläcne bei geringem Abwasserzulauf und damit verbundener geringerer Zentrifugalwirkung geschützt wird.Solutions: The tasks were solved in that the heat exchanger in the center of the separator (clean side) and additionally through Abweisfläcne with low wastewater inflow and the associated lower centrifugal effect is protected.

Um bei Unterlassung einer Abschlämmung des Grobschmutzes keinen Rückstau in der Abwasserleitung zu erhalten, wurde das System mit einem Sicherheitsüberlauf versehen. So that there is no backwater if the coarse dirt is not blown down To get into the sewer, the system was equipped with a safety overflow Mistake.

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