Abstract

The exchanger has a pipe line, where the exchanger is used as corrugated pipe made of stainless steel. The corrugated pipe is fixed at an inner wall of a sewer using dowels and mounting units e.g. snatching clamps and screwing clamps. The exchanger is lead into a sewer construction plant within an elbow of the sewer. The exchanger supports an exhaust valve in a returning place within a vertex of the elbow.

Description

Stand der TechnikState of the art

Die bisher in Abwasserkanälen verwendeten Wärmetauscher arbeiten nach dem Prinzip des Flächenwärmetauschers. Hierzu wurde in den Sohlbereich der Kanalrohre ein Gerinne aus Metall eingebaut, durch das der Wärmeübergang vom Medium Abwasser auf die Leitungen erfolgt, welche mit der Wärmepumpe verbunden sind. Die bisherige Lösung lässt sich nur bei Abwasserkanälen größeren Durchmessers (DN > 800) in Zusammenhang mit dem Neubau oder Ersatzneubau von Kanälen anwenden.The so far in sewers used heat exchanger work on the principle of the surface heat exchanger. For this purpose, a channel made of metal was in the bottom of the sewer pipes built-in, through which the heat transfer from the medium sewage on the lines takes place, which with the heat pump are connected. The previous solution can be only with sewers larger diameter (DN> 800) to apply with the new construction or replacement of canals.

Der Erfindung zu Grunde liegendes ProblemThe invention is based on lying problem

Der in den Schutzansprüchen 1 bis 7 angegebenen Erfindung liegt das Problem zugrunde, einen Wärmetauscher zu entwickeln, der unkompliziert in Abwasserrohren kleinerer Dimensionen einsetzbar ist.Of the in the protection claims 1-7 indicated invention is based on the problem, a heat exchangers to develop uncomplicated in sewer pipes of smaller dimensions can be used.

Dies soll in bestehenden Systemen und bei der Neuverlegung von Abwasserkanälen möglich sein.This should be possible in existing systems and in the relocation of sewers.

Problemlösung (Erfindung)Problem solving (invention)

Das angegebene Problem wird mit den in den Schutzansprüchen 1 bis 7 dargestellten Merkmalen gelöst.The indicated problem is with the protection claims 1 to 7 illustrated features solved.

Mit der Erfindung wird erreicht, dass in bestehende und neu zu bauende Abwasserkanäle ein Wärmetauscher eingebaut werden kann. Darüber hinaus lässt sich durch die Erfindung die Nachrüstung vorhandener Abwasserleitungen schnell und ohne Unterbrechung der Abwasserableitung durchführen.With The invention is achieved that in existing and new to build sewers a heat exchanger can be installed. About that lets out the retrofitting of existing sewers by the invention perform quickly and without interruption of the wastewater discharge.
