Abstract
Description
Die Erfindung betrifft eine Anordnung zur optischen Visualisierung und Vermessung von mikroskopischen Vorgängen in Prozessen bei hoher Temperatur und/oder hohem Druck.The The invention relates to an arrangement for optical visualization and Measurement of microscopic processes in processes at high Temperature and / or high pressure.
In vielen Industriezweigen, wie der Chemie-, Bio-, Pharma-, Umwelt- und Energieverfahrenstechnik sind chemische und physikalische Prozesse mittels geeigneter Prozessinstrumentierung zu beobachten, zu überwachen und zu steuern. Dies trifft insbesondere auf Stoffgemischströmungen in der Chemieverfahrenstechnik, der Bioverfahrenstechnik und der Lebensmittelherstellung zu.In many industries, such as the chemical, biotechnology, pharmaceutical, environmental and energy process engineering are chemical and physical processes observe, monitor, by means of suitable process instrumentation and to control. This applies in particular to mixed substance flows chemical engineering, bioprocess engineering and food production to.
Mikroskopie-Beobachtungssysteme sind dabei von besonderem Interesse, da sie dynamische Vorgänge auf mikroskopischen Skalen, etwa die Vitalität von Mikroben, die Ausbildung von Biofilmen oder das Wachstum von Partikeln, einer Beobachtung zugänglich machen. Aus der Literatur ist eine Vielzahl prozessmikroskopischer Systeme bekannt. Zumeist bestehen diese Lösungen aus einer einfachen Kombination einer Beleuchtungseinheit und einer Kameraeinheit mit einer abbildenden Optik. Alle bekannten Lösungen können nur bei ausreichend niedrigen Drücken und Temperaturen eingesetzt werden, da immer Teile des abbildenden Systems (Optiken, Kunststoffteile) bzw. Elektronikbestandteile (LED-Beleuchtung, Kamerakomponenten) Limitationen bezüglich des Drucks und hauptsächlich der Temperatur unterliegen.Microscopy observation systems are of particular interest because they have dynamic processes microscopic scales, such as the vitality of microbes, training of biofilms or the growth of particles, an observation accessible do. From the literature is a variety of process microscopy Known systems. In most cases, these solutions consist of a simple Combination of a lighting unit and a camera unit with an imaging optics. All known solutions can only be sufficiently low To press and temperatures are used, as always parts of the imaging Systems (optics, plastic parts) or electronic components (LED lighting, camera components) Limitations regarding of pressure and mainly subject to temperature.
Systemlösungen für Prozesse mit Temperaturen oberhalb 50°C sehen daher immer eine genügende räumliche Trennung der temperaturempfindlichen Bauteile vom Prozessort vor. Dies ist aber oft ein Nachteil, da besonders die Übertragung des Bildes vom Prozessort zur Kameraeinheit über lange Distanzen mittels einer temperaturunempfindlichen Optik zu hohen Lichtverlusten im Strahlengang führt. Dies kann unter Umständen dazu führen, dass aufgrund des Lichtverlustes lange Belichtungszeiten der Kamera erforderlich sind, die es nicht möglich machen, schnelle Prozesse scharf abzubilden.System solutions for processes with temperatures above 50 ° C therefore always see a sufficient spatial Separation of the temperature-sensitive components from the processor. But this is often a disadvantage, especially the transmission the image from the processor to the camera unit over long distances by means of a temperature insensitive optics to high light losses in the Beam path leads. This may possibly cause that due to the loss of light long exposure times of the camera are required, which does not allow fast processes sharp picture.
Aufgabe der vorliegenden Erfindung ist es, eine Anordnung für ein Prozessmikroskop anzugeben, bei dem die Kameraeinheit möglichst nah am Prozessort angeordnet ist. Dabei soll die Anordnung durch konstruktive Gestaltung in der Lage sein, die Kameraeinheit vor unzulässig hohen Temperaturen, die am Prozessort auftreten können, zu schützen und ohne gleichzeitig einen starken Wärmeentzug aus dem Prozessmedium über eine aktive Kühlung des Konstruktionsmaterials des Prozessmikroskops zu verursachen.task The present invention is an arrangement for a process microscope specify where the camera unit as close to the processor location is. The arrangement should by constructive design in the Be able to protect the camera unit from inadmissibly high temperatures, the can occur at the processor to protect and at the same time a strong heat extraction from the process medium via a active cooling of the design material of the process microscope.
Die Erfindung überwindet die Nachteile bekannter Lösungen durch folgende Merkmale:
- – Beleuchtungsoptik und Kamera sind in einem einzigen bzw. in getrennten Schutzkörpern untergebracht, innerhalb derer eine Vakuumkammer für eine optimale thermische Isolation sorgt.
- – Die durch die Vakuumkammer gestrahlte bzw. über vorhandene Materialverbindungen geleitete Wärme wird von den innen liegenden Strukturen des Prozessmikroskops über eine wärmeleitende Zylinderringstruktur und einen daran angeschlossenen Kühlkörper abgeführt.
- - Lighting optics and camera are housed in a single or in separate protective bodies, within which a vacuum chamber ensures optimum thermal insulation.
- The heat radiated through the vacuum chamber or conducted via existing material connections is dissipated by the internal structures of the process microscope via a thermally conductive cylinder ring structure and a heat sink connected thereto.
