Vorrichtung zur Einführung eines Vergieichsthermometers in einen in Betrieb befindlichen BehälterDevice for introducing a comparison thermometer into a container in operation
Die Erfindung betrifft eine Vorrichtung zur Einführung eines Vergleichsthermometers in einen in Betrieb befindlichen Behälter, bei dem im Behälter ein über die Länge verteilt mehrere Meßstellen aufweisendes, von einem Schutzrohr umgebenes, Thermometer fest angeordnet ist.The invention relates to a device for introducing a comparison thermometer into a container in operation, in which a thermometer having several measuring points distributed over the length and surrounded by a protective tube is fixedly arranged in the container.
In Tanklagern oder Lager- oder Prozeßbehältern der chemischen oder petrochemischen Industrie kommen häufig sog. Multipoint Widerstandthermometer zum Einsatz. Diese Thermometer sind fest im Behälter angeordnet, und zwar üblicherweise in einem entsprechenden Schutzrohr. Verteilt über die axiale Länge weisen diese Thermometer einzelne Meßstellen auf, so daß während des Betriebes des Behälters in verschiedenen Ebenen ständig Temperaturmessungen durchgeführt werden können.So-called multipoint resistance thermometers are often used in tank farms or storage or process vessels in the chemical or petrochemical industry. These thermometers are permanently installed in the vessel, usually in a corresponding protective tube. These thermometers have individual measuring points distributed over the axial length, so that temperature measurements can be carried out continuously at different levels during operation of the vessel.
Von Zeit zu Zeit ist eine Nacheichung dieser Thermometer notwendig. Hierzu mußte ein Vergleichsthermometer in den Behälter - neben dem festen Thermometer - eingebracht werden oder das zu überprüfende Thermometer mußte aus dem Behälter herausgenommen werden. Dazu war ein Stillsetzen des Behälters notwendig oder es mußten sehr hohe Sicherheitsvorkehrungen getroffen werden, um während des laufenden Betriebes diese Überprüfung vornehmen zu können. Der Kosten- und Zeitaufwand war damit nicht unerheblich.From time to time, these thermometers need to be recalibrated. To do this, a comparison thermometer had to be placed in the container - next to the fixed thermometer - or the thermometer to be checked had to be taken out of the container. This required the container to be shut down or very strict safety precautions had to be taken in order to be able to carry out this check during ongoing operation. The cost and time involved were therefore not insignificant.
Der Erfindung liegt die Aufgabe zugrunde eine Möglichkeit zu schaffen, mit der auch während des Betriebes eines Behälters eine Überprüfung oderThe invention is based on the object of creating a possibility with which even during the operation of a container a check or
Nacheichung des in diesem eingesetzten festen Thermometers erfolgen kann, und zwar mit geringem Zeit- und Montageaufwand und somit geringen Kosten.Recalibration of the fixed thermometer used in this can be carried out with little time and installation effort and therefore low costs.
Gelöst wird diese Aufgabe erfindungsgemäß dadurch, daß im Schutzrohr eine sich über dessen axiale Länge erstreckende Führung vorgesehen ist, in die ein Vergleichsthermometer von außen einführ- und bis zu den jeweiligen Meßstellen des festen Thermometers absenkbar ist.This object is achieved according to the invention in that a guide is provided in the protective tube which extends over its axial length and into which a comparison thermometer can be inserted from the outside and lowered to the respective measuring points of the fixed thermometer.
Die Führung im Schutzrohr kann als Führungsrohr oder Führungsschlauch ausgebildet sein. Wesentlich ist deren permanente Anordnung im Schutzrohr und Nähe zum festen Thermometer, d.h. das Vergleichsthermometer kann zu beliebiger Zeit in die Führung eingeführt werden, ohne das es eines Stillsetzens des Behälters oder des Prozesses bedarf, in den der Behälter integriert ist. Auch erübrigt sich ein Ausbau des festen Thermometers allein zum Zweck der Überprüfung oder Eichung.The guide in the protective tube can be designed as a guide tube or a guide hose. It is important that they are permanently arranged in the protective tube and close to the fixed thermometer, i.e. the comparison thermometer can be inserted into the guide at any time without having to shut down the container or the process in which the container is integrated. There is also no need to remove the fixed thermometer just for the purpose of checking or calibrating.
Damit lassen sich nicht nur der Zeitaufwand sondern im besonderen Maße auch die Kosten für eine Nacheichung oder Überprüfung eines in einem Behälter fest angeordneten Thermometers reduzieren.This not only reduces the time required but also, to a large extent, the costs for recalibrating or checking a thermometer that is permanently installed in a container.
Die flexible Ausbildung des Vergleichsthermometers ermöglicht darüber hinaus auch Nachmessungen an gekrümmten Thermometern.The flexible design of the comparison thermometer also enables follow-up measurements on curved thermometers.
Die Erfindung soll nachfolgend an einem Ausführungsbeispiel erläutert werden, wobei hier lediglich schematisch ein Prozeßbehälter im Schnitt dargestellt ist.The invention will be explained below using an embodiment example, whereby a process container is shown here only schematically in section.
In dem Behälter 1 befindet sich in einem Schutzrohr 4 ein Thermometer 2, das über die axiale Länge verteilt, mehrere Meßstellen 3 aufweist.In the container 1, a thermometer 2 is located in a protective tube 4, which has several measuring points 3 distributed over the axial length.
Das Schutzrohr ist selbstverständlich abgedichtet in den Behälter eingesetzt. Mit einem derartigen Thermometer lassen sich während des Betriebes des Behälters Temperaturmessungen in verschiedenen Meßebenen durchführen.The protective tube is of course sealed when inserted into the container. With such a thermometer, temperature measurements can be carried out at different measuring levels while the container is in operation.
In dem Schutzrohr befindet sich eine Führung 5, beispielsweise in Art eines Führungsrohres oder Führungsschlauches, die sich über die gesamte axiale Länge des Schutzrohres 4 erstreckt. Da diese Führung sich innerhalb des Schutzrohres befindet bzw. mit diesem in den Behälter eingesetzt ist, ist sie ebenfalls gegenüber dem Behälterinneren abgedichtet. Durch diese Führung kann nun jederzeit ein Vergleichsthermometer 6 eingeführt und soweit abgesenkt werden, daß eine Einstellung auf die jeweilige in unterschiedlicher Höhe liegende Meßstelle möglich ist, so daß diese dann gezielt überprüft oder geeicht werden kann.In the protective tube there is a guide 5, for example in the form of a guide tube or guide hose, which extends over the entire axial length of the protective tube 4. Since this guide is located inside the protective tube or is inserted into the container with it, it is also sealed from the inside of the container. A comparison thermometer 6 can now be inserted through this guide at any time and lowered to such an extent that it can be adjusted to the respective measuring point at a different height, so that this can then be specifically checked or calibrated.
