Abstract

The method uses single or multiple self-dissolving pigs (1). The pigs are adapted in shape to the shape of the pipeline. They are pressed through the pipe (3) using a propellant, or are drawn through by underpressure. Pigs and propellant can be introduced via a sealing insert socket (5) into pipe openings (4), which are for operation of the pipe system only, and are not normally arranged for use of pigs and propellant. After cleaning has been completed, the pigs dissolve, by changing from solid to liquid or gaseous shape.

Description

Die Erfindung bezieht sich auf ein Rohrreinigungsver­ fahren, bei dem Molche und Treibmedium dem zu reinigenden Rohrsystem auch über vorhandene Öff­ nungen zugeführt werden können und dessen Molche sich nach dem Reinigungsvorgang auflösen.The invention relates to a Rohrreinigungsver drive with the newts and propellant cleaning pipe system also via existing public can be supplied and its newts dissolve after the cleaning process.

Verfahren zur Rohrreinigung mit Molchen sowie diverse Molch-Varianten sind u. a. aus PS DE 30 32 532 bekannt geworden. Hierbei werden Molche mittels entsprechender Stationen dem Rohrlei­ tungssystem zugeführt bzw. entnommen. Zu Reini­ gungszwecken werden die Molche mit dem Leitungs­ medium oder einem speziellen Reinigungsmedium (z. B. Wasser oder Luft) durch die Leitung getrieben.Processes for cleaning pipes with pigs as well various pig variants are u. a. out PS DE 30 32 532 become known. Here are Pigs to the Rohrlei using appropriate stations system supplied or removed. To Reini The newts are connected to the pipe medium or a special cleaning medium (e.g. water or air) driven through the line.

Verfahren dieser Art haben den Nachteil, daß sie nur anwendbar sind, wenn das Rohrleitungssystem zu diesem Zweck mit Molch-Sende- und Empfangsstation ausgerüstet ist. Rohrleitungssysteme, die aus techni­ schen Gründen mit derartigen Stationen nicht ausge­ rüstet werden können oder deren Umrüstung sich aus ökonomischen Gründen verbietet, konnten bislang nicht gemolcht, sondern mußten mit weitaus zeitauf­ wendigeren Methoden gereinigt werden.Methods of this type have the disadvantage that they only are applicable if the piping system too for this purpose with a pig sending and receiving station is equipped. Piping systems made from techni reasons for such stations can be equipped or their conversion banned for economic reasons so far not pigged, but had to go by far more agile methods can be cleaned.

Der Erfindung liegt die Aufgabe zugrunde, ein Ver­ fahren zu schaffen, welches die ambulante Reinigung solcher Rohrleitungssysteme ermöglicht, die keine Molchstationen zum Senden oder Empfangen aufwei­ sen und auch sonst nicht nach molchtechnischen Ge­ sichtspunkten ausgelegt sind.The invention has for its object a Ver drive to create which is the outpatient cleaning of such piping systems that do not Pig stations for sending or receiving sen and also not otherwise according to pigging technology viewpoints are designed.

Diese Aufgabe wurde erfindungsgemäß dadurch ge­ löst, daß Molche und Treibmedium dem zu reinigen­ den Rohrleitungssystem voll außen durch eine vorhan­ dene Leitungsöffnung zugeführt werden, wofür ein Einführstutzen verwendet wird, welcher der Lei­ tungsöffnung angepaßt ist. Die Molche lösen sich nach erfolgter Rohrreinigung auf.This object has been achieved according to the invention triggers that to clean the newts and propellant the piping system fully outside by an existing whose line opening are fed, for which a Introducer is used, which is the Lei opening is adjusted. The newts dissolve pipe cleaning.

Der Vorteil des erfindungsgemäßen Rohrreinigungs- Verfahrens liegt in der Möglichkeit, es ambulant für Rohrsysteme einzusetzen, welche nicht für Molchver­ fahren im herkömmlichen Sinn ausgerüstet sind. Es ist nicht Orts- bzw. Systemgebunden und ermöglicht das Anbieten der Molchreinigung von Rohrleitungen als Dienstleistung. Eine herkömmliche Molch-Sende­ station wird durch den erfindungsgemäßen Einführ­ stutzen ersetzt. Durch das Auflösen der erfindungsge­ mäßen Molche nach erfolgter Rohrreinigung kann die Molch-Empfangsstation entfallen. The advantage of the pipe cleaning according to the invention The procedure lies in the possibility of making it outpatient Use pipe systems that are not for Molchver are equipped in the conventional sense. It is not tied to a specific location or system and enables that Offer the pig cleaning of pipes as Service. A conventional newt broadcast station is introduced by the introduction nozzle replaced. By dissolving the fiction moderate pigs after cleaning the pipe Pig receiving station is eliminated.  

Vorteilhafte Ausgestaltungen des erfindungsgemäßen Verfahrens und der dazugehörigen Molche sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention Procedures and the associated pigs are in specified in the subclaims.

Die Auflösung der Molche kann z. B. dadurch erfol­ gen, daß der Molchkörper aus gefrorenem Wasser besteht und nach erfolgtem Durchlaufen der zu reini­ genden Rohrleitung in einem Behälter am Ende der Leitung verbleibt und dort schmilzt.The pigs can be dissolved e.g. B. thereby successful gene that the pig body from frozen water exists and after passing through to reini pipe in a container at the end of the The pipe remains and melts there.

Die abrasiven Eigenschaften des Molches können beispielsweise durch die Beimengung von Quarzsand zur Gefrierflüssigkeit erzeugt werden.The pig's abrasive properties can for example by adding quartz sand to the freezing liquid.

Eine biegeweiche Kupplung zweier oder mehrerer Molche aus gefrorenem Wasser kann z. B. aus einem Stück Naturfaserseil bestehen, dessen Enden in den Molchen festgefroren sind bzw. das den Molch durch­ läuft und auf ganzer Molchlänge eingefroren ist.A flexible coupling of two or more Pigs from frozen water can e.g. B. from one Pieces of natural fiber rope exist, the ends of which in the Pigs are frozen or that through the pig runs and is frozen along the entire length of the pig.

Ein Ausführungsbeispiel der Erfindung wird anhand der nachfolgenden Zeichnung erläutert. Sie zeigt eine schematische Darstellung des erfindungsgemäßen Verfahrens in Form einer ambulanten Reinigungs- Molchanlage (14) und eines teilweise und schema­ tisch dargestellten Rohrleitungssystems (9).An embodiment of the invention is explained with reference to the following drawing. It shows a schematic representation of the method according to the invention in the form of an outpatient cleaning pig system ( 14 ) and a partially and schematically shown piping system ( 9 ).

Das Rohrleitungssystem z. B. einer Flugzeug- Toilettenanlage (9) weist eine Leitung (3) und Lei­ tungsabzweigungen (4, 10) sowie einen Sammelbehäl­ ter (11) auf. An eine vorhandene Leitungsabzweigung (4) - z. B. einem Flugzeug-Toilettenanschluß - wird der Einführungsstutzen (5) dichtend angeschlossen, durch welchen der Molch (1) von dem Treibmedium (2) - z. B. Wasser - in das Rohrleitungssystem getrie­ ben wird. Das Treibmedium wird z. B. mittels einer Pumpe (12) druckbeaufschlagt. Der Molch (1) fährt durch die Leitung, wobei er in der Mehrfachmolch- Ausführung (7) Rohrabzweigungen (10) überwindet, nachdem diese mit Treibmedium verfüllt sind. Durch seine dem Rohrleitungsdurchmesser angepaßten Form sowie seine abrasiven Eigenschaften entfernt der Molch Verunreinigungen (13) innerhalb des Roh­ res, bis er zusammen mit den Verunreinigungen den Sammelbehälter (11) erreicht. Innerhalb des Sammel­ behälters (11) löst sich ein aus gefrorenem Wasser bestehender Molch durch Schmelzen auf und geht in das gespeicherte Treibmedium über (6).The piping system z. B. an aircraft toilet system ( 9 ) has a line ( 3 ) and Lei line branches ( 4 , 10 ) and a collecting container ter ( 11 ). To an existing line junction ( 4 ) - z. B. an aircraft toilet connection - the inlet connection ( 5 ) is sealingly connected, through which the pig ( 1 ) from the propellant ( 2 ) - z. B. water - in the piping system is ben ben. The propellant is e.g. B. pressurized by means of a pump ( 12 ). The pig ( 1 ) travels through the line, overcoming pipe branches ( 10 ) in the multiple-pig version ( 7 ) after these have been filled with propellant. Due to its shape adapted to the pipe diameter and its abrasive properties, the pig removes impurities ( 13 ) within the tube until it reaches the collecting container ( 11 ) together with the impurities. Within the collection container ( 11 ), a pig consisting of frozen water dissolves by melting and passes into the stored propellant ( 6 ).
