Abstract

The warm water is collected in an insulated (2,4) tank and a heat exchange is generated with a coil cooler (5) controlled by magnetic valves, thus increasing the water forward flow temp. The heat exchange is pref. carried out by a pump. If the system is used for toilet waste water, instead for clean one, a comminuter for the sewage is incorporated in the collector tank.

Description

Durch die Verknappung der weltweiten Energiereserven und der Umweltbelastung durch das Verbrennen fociler Brennstoffe werden Maßnahmen zur Energieeinsparung immer wichtiger und wirtschaftlicher.Due to the scarcity of global energy reserves and environmental pollution burning focil fuels are becoming energy saving measures more important and economical.

Da die Möglichkeiten hierzu weitestgehend ausgeschöpft, oder nur durch ein wesentlichen Kapitaleinsatz zu verbessern sind, bietet sich die Möglichkeit der Wärmerückgewinnung als preiswerte Möglichkeit der Energieeinsparung an.Since the possibilities for this have been largely exhausted, or only by an essential one Capital investment can be improved, there is the possibility of heat recovery as inexpensive way of saving energy.

Bisher wurde erwärmtes und gebrauchtes Wasser ungenutzt in die Kanalisation abgelassen.So far, heated and used water has not been used in the sewage system drained.

Der Erfindung liegt die Aufgabe zugrunde, Abwasser und Regenwasser aus Haushalten, Gewerbe und Landwirtschaft zur Warmwassererzeugung heranzuziehen bei geringem Eigenenergieverbrauch.The invention has for its object waste water and rainwater from households, Use trade and agriculture to produce hot water at low Own energy consumption.

Eine zum Ausführen des Verfahrens geeignete Anlage zeigt die Zeichnung.The drawing shows a system suitable for carrying out the method.

Nach der Erfindung fließt das anfallende erwärmte Abwasser und Regenwasser über die Zuleitung (1), in den Sammelbehälter (2) der mit einer Wärmeisolierung (4) versehen ist. Das anfallende Abwasser stammt aus dem im Gebäude vorhandenen Abwassernetz, wobei bei Neubauten eine Trennung des mit Fäkalien verunreinigten Abwassers sinnvoll ist. Ist dieses baulich nicht möglich, läßt sich im Sammelbehälter ein Zerkleinerer bzw. eine Schmutzwasserpumpe installieren.According to the invention, the resulting heated wastewater and rainwater flows via the feed line ( 1 ) into the collecting container ( 2 ) which is provided with thermal insulation ( 4 ). The resulting wastewater comes from the wastewater network in the building, although in new buildings it makes sense to separate the wastewater contaminated with faeces. If this is not structurally possible, a shredder or a dirty water pump can be installed in the collection container.

In Kombination mit einer Regenwassersammelanlage, läßt sich die Anlage mit dem ansonsten in die Kanalisationsanlage abzuleitenden Regenwasser beschicken. Dieses Regenwasser ist aufgrund der Sonneneinstrahlung stark erwärmt.In combination with a rainwater collection system, the system can be used with the otherwise feed rainwater to be drained into the sewage system. This Rainwater is very warm due to the sun's rays.

Die Erfindung wird vorzugsweise im Keller positioniert, um die Schwerkraft des Abwassers auszunutzen. Eine Beschickung der Anlage mit Schmutzwasserhebeanlagen ist aber jederzeit möglich.The invention is preferably positioned in the basement to control the gravity of the sewage to take advantage of. However, loading the system with waste water lifting systems is anytime possible.

Ist der Behälter gefüllt, und wird nicht genug Abwasser entnommen, fließt das überschüssige Abwasser über einen Ablauf (3) in die Kanalisation ab. Der Ablauf dient gleichzeitig zur Belüftung des Abwassernetzes.If the tank is filled and not enough wastewater is removed, the excess wastewater flows into the sewage system via a drain ( 3 ). The drain also serves to ventilate the sewage network.

Wird aus der Abgangsleitung (6) Frischwasser entnommen, schließt der Differenzdruck­ schalter (10) und öffnet den Motorschieber (8) und das Magnetventil (9).If fresh water is taken from the outlet line ( 6 ), the differential pressure switch ( 10 ) closes and opens the motorized slide ( 8 ) and the solenoid valve ( 9 ).

Durch den isolierten Schlangenkühler (5) fließt nun das gesammelte Abwasser und gibt die gespeicherte Wärme an das über die Zuleitung (7) fließende Wasser ab.The collected wastewater now flows through the insulated snake cooler ( 5 ) and releases the stored heat to the water flowing through the feed line ( 7 ).

Um einen höheren Wirkungsgrad der Erfindung zu erlangen, kann anstelle des Schlangen­ kühlers eine Wärmepumpe angeordnet werden.In order to achieve a higher efficiency of the invention, instead of the snake cooler a heat pump can be arranged.

Vorteil des Verfahrens ist die Nutzung von ungenutzter Abwasserwärme bei geringen Eigenenergieverbrauch, verbunden mit geringen Anlagenkosten.The advantage of the process is the use of unused waste water heat at low Own energy consumption combined with low system costs.
