Description

Verfahren zum Lösen und Entfernen von Ablagerungen und Anlagerungen in Kanälen und Rohren Bei den bisher bekannten Verfahren zum Reinigen von Kanälen und Rohren ist es erforderlich, mindestens Aden jeweils der Reinigung unterworfenen Abschnitt stillzusetzen und für das in dem Kanal oder Rohr geförderte flüssige, dampf-oder gas@förmi.ge Medium eine Hilfeleitung vorzusehen. Dieses Erfordernis bringt in der Praxis häufig fast unüberwindliche Schwierigkeiten, erhebliche Betriebsausfälle, ja häufig die Stillegung eines ganzen Betriebes mit sich.Process for loosening and removing deposits and deposits in ducts and pipes In the previously known methods for cleaning ducts and pipes it is required to have at least adene each subjected to purification Shut down section and for the pumped in the channel or pipe liquid, steam or gas@formi.ge medium an auxiliary line should be provided. This requirement in practice often brings almost insurmountable difficulties, significant operational downtimes, yes, often with the closure of an entire company.

.Diese Unzuträglichkeiten der bekannt-en, bisher allgemein angewandten Reinigungsverfahren werden durch das Verfahren gemäß der vorliegenden Erfindung beseitigt, welches erstmals eine Reinigung von Rohrleitungen und allgemein das Lösen und Entfernen von Ablagerungen und Anlagerungen in Kanälen und Rohren gestattet, während (diese von dem flüssigen, dampf- oder gasförmigen Medium durchströmt werden, das betriebsmäßig in ihnen fortgeleitet wird...These disadvantages of the known, previously generally used Purification methods are carried out by the method according to the present invention eliminated, which for the first time a cleaning of pipes and general loosening and removal of deposits and deposits in channels and pipes allowed, while (these are flowed through by the liquid, vapor or gaseous medium, which is operationally forwarded in them ..

Das Verfahren gemäß der vorliegenden Erfindung, das im Vergleich mit allen bisher bekannten Verfahren u. a. eine recht erhebliche Arbeitszeitersparnis mit sich bringt, besteht im Prinzip darin, daß die an Iden inneren Rohrwandungen entstandenen Schmutz- oder sonstigen Ab- und Anlagerungen durch longitudinale und/oder kreisförmige Impulse eines hydraulischen Mediums oder eines Gewindes verschiedener hydraulischer Medien gelockert und schließlich entfernt werden.The method according to the present invention compared with all previously known methods, inter alia. quite a considerable saving in working time brings with it, consists in principle that the inner pipe walls on Iden dirt or other deposits and deposits caused by longitudinal and / or circular impulses of a hydraulic medium or a thread of various types hydraulic media are loosened and finally removed.

Diese Impulse werden erfindungsgemäß durch an einer oder mehreren Stellen des Rohres vorzugsweise tangential unter Druck und stoßweise oder intermittierend zugeleitete flüssige und/oder dampfförmige und/oder gasförmige Medien erzeugt und können in ihrer Wirkung noch durch einen am Ende der zu behandelnden Rohrstrecke erzeugten Sog unterstützt werden.According to the invention, these pulses are transmitted to one or more Place the pipe preferably tangentially under pressure and intermittently or intermittently supplied liquid and / or vapor and / or gaseous Media is generated and its effect can still be achieved by one at the end of the treatment Pipe section generated suction can be supported.

Werne idase zu reinigende Rohr betriebsmäßig unidl während des Reinigungsprozesses von einer Flüssigkeit durchströmt wird, wird als die Impulse erzeugendes hydraulisches Medium die gleiche Flüssigkeit oder ein dampfförmiges oder gasförmiges- Meidium oder Gemische dieser Medien verwendet. Handelt es sich um ein betriebsmäßig und während des Reinigungsprozesses von Dampf oder Gas durchströmtes Rohr, .so wird zur Erzeugung der Impulse zweckmäßigerweise eine inerte und/oder mit dem in dem Rohr strö.menden Gas oder Dampf nicht reagierende Flüssigkeit verwendet.If the pipe to be cleaned is operationally flowed through by a liquid during the cleaning process, the same liquid or a vaporous or gaseous medium or a mixture of these media is used as the hydraulic medium generating the impulses. If it is .so of the pulses is used to generate suitably an inert and or used with the non-reactive in the tube strö.menden gas or vapor to liquid flowed through operationally and during the cleaning process of steam or gas pipe, /.

Zur Unterstützung der Wirkung der erfindungsgemäß verwendeten hydraulischen Medien können außer den genannten hydraulischen Stoffen auch feste, stückige Materialien, wie z. B. Sand, Schotter, Kies od. dgl., zusätzlich in die zu behandelnde Rohrleitung eingeschleust werden.To support the effect of the hydraulic used according to the invention In addition to the hydraulic substances mentioned, media can also include solid, lumpy materials, such as B. sand, crushed stone, gravel or the like. In addition to the pipeline to be treated be smuggled in.

Außer den festen, stückigen Materialien können erfindungsgemäß zur Unterstützung der Impulswirkung Kratzen, Rund- oder Zylinderbürsten od. dgl. in das Rohr eingebracht und mittels der unter Druck eingeleiteten hydraulischen Medien in dem Rohr vorwärts getrieben werden.In addition to the solid, lumpy materials can according to the invention for Support of the impulse effect scratching, round or cylinder brushes or the like in introduced the pipe and by means of the hydraulic media introduced under pressure propelled forward in the pipe.

Um bei langen Rohrleitungen oder Kanälen den jeweiligen Standort der eingebrachten Kratzen, Bürsten od. dgl. feststellen zu können, werden diese Reinigungskörper mit einer radioaktiven Substanz od..dgl. versehen, deren Strahlung außerhalb des Rohres mittels an sich bekannter physikalischer Meßgeräte nachgewiesen. werderhkann.In order to determine the respective location of the introduced scratches, brushes or the like. To be able to determine these cleaning bodies with a radioactive substance or the like. provided whose radiation is outside the Rohres detected by means of known physical measuring devices. who can.

Das Verfahren kann auch dann zur Anwendung kommen, während -sich @dlie Rohre in Betrieb befinden, d. h. während sie in betriebsmäßiger Weise von flüssigen, dampf- und/ader gasförmigen Medien durchströmt werden, wen die zur Erzeugung der Impulswirkung dienenden- festen und/oder flüssigen und/öder dampfförmigen und/oder gasförmigen Stoffe in den Betrieb nicht störender Weise in die zu behandelnden Rohre eingeschleust und aus ihnen wieder ausgeschleust werden.The procedure can also be used while -she @dlie Pipes are in operation, d. H. while they are in an operational manner of liquid, Vapor and / or gaseous media are flowed through if the to generate the Impulse effect serving solid and / or liquid and / or vaporous and / or gaseous substances in the operation do not interfere with the pipes to be treated be introduced and discharged from them again.

An Stelle eines Kompressors können zur Erzeugung der Pulsationen` und zum Komprimieren oder in das zu behandelnde Rohr einzuschleusenden flüssigen, dampf- oder gasförmigen Medien auch die Abgase einer Brennkraftmaschine unmittelbar verwendet werden, welche die im Sinne ides vorliegenden Verfahrens notwendigen Druckschwankungen bereits aufweisen. Diese Abgase können entweder direkt als Gase in das zu reinigende Rohr oder aber in einen die Spülflüssigkeit enthaltenden Behälter, e. B. einen Kesselwagen od, dgl., eingeleitet werden.Instead of a compressor, you can generate the pulsations and for compressing or injecting liquid into the pipe to be treated, Vapor or gaseous media also direct the exhaust gases from an internal combustion engine are used, which are the necessary pressure fluctuations in the sense of the present method already have. These exhaust gases can either be fed directly into the gas to be cleaned Tube or in a container containing the rinsing liquid, e. B. a tank car od, like. Be initiated.

In der Praxis kann die Reinigung beispielsweise eines im Erdreich verlegten Rohres in der Weise vorgenommen werden, daß sowohl an der gewählten Eintrittmtelle als auch an ider Austrittsstelle für die hydraulischen Medien jeweils ein Kesselwagen von hinreichender Druckfestigkeit stationiert wird, so daß die von 'dem einen Kesselwagen beispielsweise in eine gasführende Leitung mit Druckimpulsen hineingedirückte Flüssigkeit von idem randeren Kesselwagen an der Austrittsstelle wieder aufgenommen werden kann.In practice, cleaning can be done in the ground, for example laid pipe can be made in such a way that both at the selected entry point as well as a tank car each at the outlet point for the hydraulic media is stationed of sufficient compressive strength so that the one tank car For example, liquid forced into a gas-carrying line with pressure pulses can be picked up again from the edge of the tank car at the exit point.

Es ist zweckmäßig, innerhalb der Kesselwagen einen Absetzraum od. dgl. vorzusehen, in welchem sich die aus dem .gereinigten Rohr entfernten Schmutzteile, Sedimente u. dgl. sowie auch die in die Rohrleitung zum Zwecke der Reinigung eingebrachten stückigen Materialien absetzen können, so daß die darüber stehende Flüssigkeit für erneute Verwendung zur Verfügung steht.It is useful to have a sedimentation room within the tank wagons. The like. Provide in which the dirt particles removed from the .greinierter pipe, Sediments and the like, as well as those introduced into the pipeline for cleaning purposes Lumpy materials can settle, so that the liquid above it for re-use is available.

In chemischen Betrieben können -die beispielsweise zum Entfernen der sich an den Rohrwan-(dungen absetzenden Reaktionsprodukte od. dgl. dienenden, nach dem Prinzip der vorliegenden Erfindung arbeitenden Anlagen auch stationär eingebaut werden.In chemical plants, for example, they can be used to remove the reaction products or the like, which are deposited on the pipe walls, after The principle of the present invention working systems also installed in a stationary manner will.
