Abstract

In the installation according to the invention, hot waste water arising in a building is collected in an insulated collecting container. Installed in the collecting container are pipe coils (2), by which the heat is taken up for further use. Connected to the collecting container is an inflow line (4) which branches off from a waste-water collecting line, as well as an outflow line (7) which, behind it, leads into the waste-water collecting line (3). The control of the water flow takes place by valves (5, 8) which are thermostatically controlled. <IMAGE>

Description

"Anlage zur Wärmerückgewinnung aus häuslichem Abwasser""System for heat recovery from domestic wastewater"

Die Erfindung geht davon aus, daß in Häusern sowie in Industrie· und Gewerbebetrieben sehr viel warmes Abwasser anfällt, das ungenutzt abfließt und einen erheblichen Energieverlust darstellt. The invention is based on the fact that in houses as well as in industry and commercial operations, there is a lot of warm wastewater that flows away unused and represents a considerable loss of energy.

Aus dieser Erkenntnis heraus hat sich der Erfinder folgende Aufgabe gestellt:From this knowledge, the inventor set himself the following task:

Mit einfachen Mitteln soll eine Anlage zur automatischen Rückgewinnung der Wärmeenergie aus warmem Schmutzwasser geschaffen werden.A system for the automatic recovery of thermal energy from warm wastewater is to be created with simple means will.

Diese Aufgabe wird im Prinzip durch eine Anlage mit den Merkmalen des Patentanspruches gelöst.This object is achieved in principle by a system with the features of the patent claim.

Bei einer solchen Anlage gelangt warmes Abwasser in einen isolierten Wasserbehälter mit einem Fassungsvermögen von beispielsweise 1.500 1. Kaltes Abwasser wird durch die Steuerung eines Thermostatventils unter Umgehung dieses Behälters zum Abfließen gebracht. Der J3ehälter ist mit einem Abfluß versehen, der sich öffnet, wenn das Wasser im Behälter abgekühlt ist und der geschlossen bleibt solange es noch warm ist und Wärme abgeben kann. Zur Säuberung des Behälters können die Ventile zum Durchfluß geöffnet werden.In such a system, warm wastewater enters an insulated water tank with a capacity of for example 1,500 1. Cold sewage is controlled by a thermostatic valve bypassing this container brought to drain. The container is provided with a drain that opens when the water in the container has cooled down and remains closed as long as it is still warm and can give off heat. To clean the container you can the valves are opened to allow flow.

Im Sammelbehälter sind Wasserrohre installiert, geeignet zur Aufnahme der Abwasserwärme. Diese Rohre können zum Beispiel die Rücklaufrohre einer Warmwasserheizung sein oder die Zulaufrohre einer Brauchwasserleitung. Die Rohre können aber auch an eine Wärmepumpe angeschlossen werden.Water pipes are installed in the collecting tank, suitable for absorbing the waste water heat. These tubes can for example the return pipes of a hot water heating system or the supply pipes a service water pipe. The pipes can also be connected to a heat pump.

Die Kosten der Anlage rechtfertigen die Energieersparnis vor allem bei Mehrfamilienhäusern, Wäschereien, Bädern, Hotelbetrieben, Krankenhäusern, Großküchen usw.The cost of the system justifies the energy savings especially in multi-family houses, laundries, bathrooms, hotels, hospitals, large kitchens, etc.

Im folgenden wird ein Ausführungsbeispiel der Erfindung erläutert wie im Prinzip auf der beiliegenden Zeichnung abgebildet ist.In the following an embodiment of the invention is explained as shown in principle on the accompanying drawing is.

In einem isolierten Sammelbehälter 1 mit einem Inhalt von beispielsweise 1.500 1 sind in Schlangenanordnung Wasserrohre 2 installiert, die vom Rücklauf einer Warmwasserheizung oder vom Zulauf eines Warmwasserboilers durchflossen werden. Von einer Sammelleitung 3, welche die gesamten häuslichen Abwasser aufnimmt zweigt eine Leitung 4 ab, die oben in den Sammelbehälter 1 führt. Im Bereich der Abzweigung ist ein UmIenlcventil 5 eingebaut, welches thermostatisch auf Grund der Abwassertemperatur gesteuert wird. Das Ventil 5 stellt sich automatisch so ein, daß warme Abwasser über die Leitung 4 in den Behälter 1 gelangen, während kalte Abwässer in der Abwassersammelleitung 3 bleiben.In an insulated collecting container 1 with a content of 1,500 liters, for example, water pipes 2 are installed in a serpentine arrangement, through which the return of a hot water heater or the inlet of a hot water boiler flow. A line 4 branches off from a collecting line 3, which receives all of the domestic wastewater, which leads into the collecting container 1 at the top. In the area of the junction, a diverter valve 5 is installed, which is thermostatically controlled based on the waste water temperature. The valve 5 adjusts itself automatically so that warm waste water reaches the container 1 via the line 4, while cold waste water remains in the waste water collecting line 3.

Hinter der Abzweigung mündet eine Überlaufleitung des Sammelbehälters in die Abwassersammelleitung 3 ein.An overflow line of the collecting tank opens behind the junction into the sewage collection line 3.

Bodenseitig geht vom Sammelbehälter 1 eine Ablaufleitung 7 in die Abwassersammeileitung 3 ab. Zum Öffnen und Schließen der Ablaufleitung 7 ist ein Absperrventil 8 eingebaut, das ebenfalls automatisch durch einen Thermostaten gesteuert wird« Wenn das Wasser im Sammelbehälter noch ausreichend warm ist, um Wärme an die Rohre 2 abzugeben, bleibt das Ventil 8 geschlossen. Wenn das Wasser im Sammelbehälter abgekühlt ist, dann öffnet sich das Absperrventil 8 und läßt das Wasser abfließen.On the bottom side, a drain line 7 leads from the collecting container 1 into the waste water collecting line 3. To open and close the drain line 7, a shut-off valve 8 is installed, which is also automatically controlled by a thermostat. If the water in the collecting tank is still warm enough to give off heat to the pipes 2, the valve 8 remains closed. When the water in the collecting tank has cooled down, the shut-off valve 8 opens and allows the water to drain off.
