Description
Die Erfindung betrifft Anordnungen zur optischen Visualisierung und Vermessung von mikroskopischen Vorgängen in Prozessen bei hoher Temperatur und/oder hohem Druck.The invention relates to arrangements 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 branches of industry, such as chemical, biotechnology, pharmaceutical, environmental and energy process engineering, chemical and physical processes can be observed, monitored and controlled by means of suitable process instrumentation. This applies in particular to mixtures of substances in chemical process engineering, bioprocess engineering and food production.
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 make dynamic processes on microscopic scales, such as the vitality of microbes, the formation of biofilms or the growth of particles, accessible to observation. From the literature, a variety of process microscopy systems is known. 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 be used only at sufficiently low pressures and temperatures, since always parts of the imaging system (optics, plastic parts) or electronic components (LED lighting, camera components) are subject to limitations in terms of pressure and mainly the 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 provide a sufficient spatial separation of the temperature-sensitive components from the processor. However, this is often a disadvantage, since especially the transmission of the image from the processor to the camera unit over long distances by means of a temperature-insensitive optics leads to high light losses in the beam path. Under certain circumstances, this can lead to long exposure times of the camera due to the loss of light, which do not make it possible to focus on fast processes.
Die
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.The object of the present invention is to specify an arrangement for a process microscope, in which the camera unit is arranged as close as possible to the processing location. The arrangement should be able to protect the camera unit against impermissibly high temperatures which may occur at the processing location and without at the same time causing a great deal of heat extraction from the process medium via active cooling of the construction material of the process microscope.
Die Erfindung betrifft Prozessmikroskope gemäß den unabhängigen Ansprüchen, Ausführungsformen der Erfindung ergeben sich aus den abhängigen Ansprüchen. Demgemäß können insbesondere die Nachteile bekannter Lösungen durch folgende Merkmale überwunden werden:
- – 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.
