Description
Einrichtung zum Überwachen von Gasen auf ihren Gehalt an festen Bestandteilen, insbesondere der Rauchentwicklung von Verbrennungsprozessen Das Hauptpatent bezieht sich auf eine Einrichtung zum Überwachen von Gasen auf ihren Gehalt an festen Bestandteilen, insbesondere der Rauchentwicklung von Verbrennungsprozessen, mit Hilfe einer von den zu prüfenden Gasen durchströmten, im Innern des Gasraumes liegenden Meßstrecke.Device for monitoring gases for their solid constituent content, in particular the smoke development from combustion processes. The main patent relates relate to a device for monitoring gases for their solid constituent content, in particular the smoke development from combustion processes, with the help of one of the gases to be tested flowed through the measuring section located in the interior of the gas space.
Durch die Meßstreckc wird eine Strahlung gesendet, deren Wirkung auf ein strahlenempfindliches Organ festgestellt wird. Hierbei gelangt zum Schutze der optischen Mittel (Strahlungsquelle, Linse, Spiegel, Strahlungsempfänger) vor dem Verschmutzen Spülluft zur Anwendung. Bei einer dzrartigen Einrichtung werden zwei unmittelbar ,starr miteinander verbundene Rohre verwendet, die von derselben Seite aus in den Gasraum eingeführt sind und deren öffnungen die Meßstrecke begrenzen. Die Spülluft wird dabei den Enden der Meßstrecke zugeleitet.A radiation is sent through the measuring section, its effect on a radiation-sensitive organ is detected. This comes to the protection of the optical means (radiation source, lens, mirror, radiation receiver) in front of the Contaminate purge air for application. In a dzr-like facility, two used directly, rigidly interconnected pipes coming from the same side are introduced into the gas space and their openings limit the measuring distance. The purge air is fed to the ends of the measuring section.
Um die Stabilität der Einrichtung durch intensive Kühlung der hauptsächlich thermisch beanspruchten Bauteile zu erhöhen, werden in Weiterbildung der Einrichtung nach dem Hauptpatent gemäß der vorliegenden Erfindung die beiden zur Begrenzung der Meßstrecke dienenden Rohre mittels mehrerer aus ,einem gemeinsamen Ringkanal mit Spülluft beschickter Rohrleitungen, zwischen denen das zu überwachende Gas frei hindurchtreten kann, starr miteinander verbunden.To ensure the stability of the establishment through intensive cooling of the mainly To increase thermally stressed components, are in further development of the facility according to the main patent according to the present invention, the two for limitation the measuring section serving pipes by means of several, a common ring channel Pipes filled with purge air, between which the gas to be monitored is released can pass through, rigidly connected to each other.
Auf der Zeichnung ist ein Ausführungsbeispiel des Gegenstandes der Erfindung dargestellt.In the drawing is an embodiment of the subject matter of Invention shown.
Fig. i zeigt einen Längsschnitt und Fig. 2 einen Schnitt nach der Linie AlrB der Fig. i. Die beiden zur Begrenzung der Meßstrecke dienenden Rohre i und 2 enthalten axiale Kanäle 3 und q., in deren einand°r zugekehrten erweiterten Enden 3' und q.' Spüiluftrohre 5 eingeschoben und darin befestigt sind. Es können nach Fig.2 beispielsweise drei Spülluftr ohre 5 verwendet werden. Die starr miteinander verbundenen Rohre i, 5 und q sind einseitig in den durch eine Wandung 6 begrenzten Gasraum von außen her eingeschoben.FIG. I shows a longitudinal section and FIG. 2 shows a section according to FIG Line AlrB of Fig. I. The two pipes used to limit the measuring section i and 2 contain axial channels 3 and q., in whose one and ° r enlarged Ends 3 'and q.' Purge air pipes 5 are inserted and fixed therein. It can According to Figure 2, for example, three scavenging tubes 5 can be used. The rigid with each other connected pipes i, 5 and q are bounded on one side by a wall 6 Gas compartment pushed in from the outside.
Zur ständigen betriebsmäßigen Durchspülung der Rohre 5 wird zweckmäßig Druckluft oder der Unterdruck der Feuerung selbst verwendet. Die Druckluft wird bei 7 zugeführt. Nach Durchtritt durch ein z. B. aus Raschigringen bestehendes Filter 8 tritt die Spülluft in einen Ringkanal 9 ein, der mittels Öffnungen io mit den Kanälen 3 des Rohres-.k: in. Verbindung steht. Ein Teil der Spü11üL tritt aus den Kanälen 3 durch enge öffnunge%@: von denen in Fig. i eine Öffnung i i sicht ist, in das Innere des Rohres i ein und die f zur Verhütung einer Verschmutzung der aus str.ähländurchlässigern Glas bestehenden Abschlußplatte i2. Diese- Glasplatte 12 verhindert ein Inberührungkommen der außerhalb des Gasraumes liegenden optischen Teile der Einrichtung mit dem zu untersuchenden Gas, wie dies sonst bei Abschaltung der Druckluftzuführung und Auseinandernehmen der außen befindlichen Teile eintreten würde.For constant operational flushing of the pipes 5 is expedient Compressed air or the negative pressure of the furnace itself is used. The compressed air will fed at 7. After passing through a z. B. from Raschig rings existing filter 8, the scavenging air enters an annular channel 9, which by means of openings io with the channels 3 of the pipe-.k: is in communication. Part of the flush occurs from the channels 3 through narrow openings: of which in FIG. i an opening i i can be seen is inside the pipe i and the f to prevent pollution the end plate i2, which is made of transparent glass. This- glass plate 12 prevents the optical elements located outside the gas space from coming into contact Parts of the facility with the gas to be examined, as would otherwise be the case with shutdown the compressed air supply and dismantling of the external parts occur would.
Etwa die Hälfte der zur Spülung verwendeten Druckluft gelangt aus den Kanälen 3' in- die Rohre 5 und durch diese in die Kanäle 4 des topfförmigen Rohres 2. Die Austrittsstelle der Spülluft aus den Kanälen 4 in das Innere des topfförmigen Rohres 2 liegt unmittelbar neben einem im Rohr 2 montierten Hohlspiegel 13, so daß die Spülluft diesen Spiegel wirksam gegen Verschmutzung schützt.About half of the compressed air used for purging comes from the channels 3 'into the tubes 5 and through them into the channels 4 of the cup-shaped tube 2. The exit point of the scavenging air from the channels 4 into the interior of the cup-shaped tube 2 is located directly next to one concave mirror 1 3 mounted in the tube 2, so that the scavenging air effectively protects this mirror against contamination.
.#.,-. Das im Gasraum befindliche Gas -wird (ärch die Spülluftrohre 5 praktisch nicht ,°ian gehindert, zwischen den einander zuehrten Enden der Rohre i und 2 hinürchzutreten. Damit ist eine gute Gewähr dafür geboten, daß sich etwaige Änderungen der Rauchstärke schnell auf die Messung auswirken.. #., -. The gas in the gas space - is ärch the Spülluftrohre 5 practically not inhibited (° ian, i between the mutually zuehrten ends of the tubes and 2 hinürchzutreten Thus a good guarantee is offered for this is that any changes in the smoke strength quickly affect the measurement. .
