Abstract

To clear fluid systems of fouling and bio-films, a hot steam generator (1) is used to deliver a hot stream into the water pipe (7) and/or electric arcs are produced in the water pipe by electrodes (16) as sparking plugs, connected to a voltage converter (12). The steamer has an inlet/outlet, a power supply (5) and a valve (3) in the feed channel to a capillary jet (6) in the water pipe. The power supply is switched on and off by a control unit (4).

Description

Kapillardüse für Einrichtungen zur Entfernung von Inkrustationen und Biofilmen in geschlossenen und/oder offenen Fluidsystemen, wobei die Einrichtungen jeweils einen Heißdampferzeuger besitzen und die Kapillardüse im Fluidsystem endet.Capillary nozzle for removal devices of incrustations and biofilms in closed and / or open Fluid systems, the devices each having a superheated steam generator own and the capillary nozzle ends in the fluid system.

In der DE 102 37 674 wird eine Einrichtung mit einem Reaktorsystem zur Entfernung von Inkrustationen und Biofilmen in Fluidsystemen mittels Heißdampf beschrieben. Dieses Reaktorsystem besteht u. a. aus einem Heißdampferzeuger mit einem Ein- und Ausgang und einer Kapillardüse als Fortsetzung des Ein- und Ausganges, wobei die Kapillardüse im Fluidsystem endet.In the DE 102 37 674 describes a device with a reactor system for removing incrustations and biofilms in fluid systems by means of superheated steam. This reactor system consists, among other things, of a superheated steam generator with an inlet and outlet and a capillary nozzle as a continuation of the inlet and outlet, the capillary nozzle ending in the fluid system.

Diese Kapillardüse kann unter bestimmten Bedingungen aufgrund der Zusammensetzung des Fluids nach längerem Einsatz völlig verkrusten.This capillary nozzle can work under certain conditions completely encrusted after long use due to the composition of the fluid.

Der Erfindung liegt das Problem zugrunde, eine Kapillardüse zu schaffen, an deren Innenwand keine Verkrustungen bzw. Ablagerungen während des Einsatzes der Kapillardüse entstehen.The invention is based on the problem, a capillary to create, no incrustations or deposits on the inner wall during the Use of the capillary nozzle arise.

Mit der Erfindung wird erreicht, dass auch über einen längeren Einsatz der Kapillardüse ein freier Austritt des Heißdampfes aus der Kapillardüse in das Fluidsystem möglich ist.With the invention it is achieved that too about a longer one Use of the capillary nozzle a free escape of the superheated steam from the capillary nozzle possible in the fluid system is.

Eine vorteilhafte Ausgestaltung der Erfindung ist im Anspruch 2 aufgeführt. In den meisten Fällen ist eine elektrische Isolation der Kapillardüse zum Behälter oder zum Rohrsystem gewünscht. Hier steckt dann die Kapillardüse in einer Art elektrischer Durchführung, die mediendicht ausgeführt ist und die elektrische Isolation zur Behälter- oder Rohrwandung garantiert.An advantageous embodiment of the Invention is listed in claim 2. In most cases electrical insulation of the capillary nozzle to the container or to the pipe system is desired. Here is then the capillary nozzle in a kind of electrical feedthrough, the media-tight and guarantees the electrical insulation to the container or pipe wall.

Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnung näher erläutert. Die Zeichnung zeigt eine Schnittdarstellung durch eine erfindungsgemäße Kapillardüse, angeordnet in einer Behälter- oder Rohrwandung.An embodiment of the invention will be closer to the drawing explained. The drawing shows a sectional view through a capillary nozzle according to the invention, arranged in a container or pipe wall.

Um die Kapillare 1 ist ein Hüllrohr 4 angeordnet. Dieses Hüllrohr 4 besitzt an der Austrittsseite (durch einen Pfeil dargestellt) eine elektrisch leitende Verbindung 5 zwischen Kapillare 1 und Hüllrohr 4, vorzugsweise ein metallischer Kreisring. Auf der gegenüberliegenden Seite, also auf der Eintrittseite der Kapillare 1, ist zwischen der Kapillare 1 und dem Hüllrohr 4 ein elektrischer Isolationsring 2 angeordnet. Der restliche Zwischenraum zwischen Kapillare 1 und Hüllrohr 4 ist mit einem elektrischen Isolationsmaterial 3 hoher Wärmebeständigkeit und geringer Wärmeleitfähigkeit gefüllt. Die Kapillare 1 und das Hüllrohr 4 besitzen außerhalb der Behälter- oder Rohrwandung 7 jeweils einen Elektroanschluss 6.Around the capillary 1 is a cladding tube 4 arranged. This cladding tube 4 has an electrically conductive connection on the outlet side (represented by an arrow) 5 between capillary 1 and cladding tube 4 , preferably a metallic ring. On the opposite side, i.e. on the entry side of the capillary 1 , is between the capillary 1 and the cladding tube 4 an electrical insulation ring 2 arranged. The remaining gap between the capillary 1 and cladding tube 4 is with an electrical insulation material 3 high heat resistance and low thermal conductivity. The capillary 1 and the cladding tube 4 have outside the container or pipe wall 7 one electrical connection each 6 ,

Durch die Stromzufuhr über die Elektroanschlüsse 6 ergibt sich über das Hüllrohr 4, die elektrische Verbindung 5 und die Kapillare 1 ein elektrischer Kreis. Durch Widerstandserwärmung erfolgt eine Aufheizung der Kapillare 1 und somit im Endeffekt eine Verhinderung einer Verkrustung der Kapillare 1. Die flüssigen oder auch gasförmigen Medien innerhalb des Behälters oder Rohrsystems können die Kapillare 1 aufgrund der Anordnung des Isolationsmaterials 3 nicht mehr wesentlich kühlen.By the power supply through the electrical connections 6 results from the cladding tube 4 who have favourited Electrical Connection 5 and the capillary 1 an electrical circuit. The capillary is heated up by resistance heating 1 and thus in the end a prevention of capillary encrustation 1 , The liquid or gaseous media within the container or pipe system can be the capillary 1 due to the arrangement of the insulation material 3 no longer cool significantly.

In den meisten Fällen des Einsatzes der Kapillardüse wird eine elektrische Isolation in Form einer elektrischen Durchführung 8 zwischen Behälter- oder Rohrwandung 7 und der Kapillardüse bzw. Hüllrohr 4 notwendig sein. Diese Durchführung 8 ist gleichzeitig mediendicht.In most cases, the use of the capillary nozzle is electrical insulation in the form of an electrical feedthrough 8th between container or pipe wall 7 and the capillary nozzle or cladding tube 4 to be necessary. This implementation 8th is also media-tight.
