Description

Vorrichtung zur Anzeige des Gewichtsunterschiedes zweier auf gleiche Temperatur und Feuchtigkeit gebrachter Gase. Das Konstruktionsprinzip vorliegender Erfindung ist auf der bekannten Tatsache aufgebaut, daß das Gewicht bzw. der Gewichtsunterschied zweier Gase, Rauchgas und Luft, die auf gleiche Temperatur und gleiche Feuchtigkeit gebracht sind, mittels einer hydrostatischen Waage gemessen werden kann. Dieses Verfahren setzt natürlich voraus, daß der geringe Druck, welcher notwendig ist, um die Gase durch den Meßapparat zu führen, dauernd gleichbleibend ist und daß vor allem das Auftreten von Widerständen in den Wegen innerhalb des Apparates, wodurch Reaktionsdrucke auftreten können, zu vermeiden ist. Insbesondere muß die Förderpumpe schlüpfungsfrei arbeiten. . Mit welchen Mitteln die Messung ermöglicht wird, ist aus der Zeichnung ersichtlich. Mit e ist ein Gefäß bezeichnet, welches mit Flüssigkeit bis etwa zur Hälfte gefüllt ist. In diese taucht die Glocke f, welche mittels Stengel h am Waagebalken i, k, l angehängt ist. Zur Erhöhung der Schwimmfähigkeit der Glocke dient der Hohlkörper g. Die Durchführung der Stengel h durch den Deckel von e geschieht mit der Stopfbüchse r.Device for displaying the difference in weight between two gases brought to the same temperature and humidity. The construction principle of the present invention is based on the known fact that the weight or the weight difference between two gases, flue gas and air, which are brought to the same temperature and the same humidity, can be measured by means of a hydrostatic balance. This method assumes, of course, that the low pressure which is necessary to lead the gases through the measuring apparatus is constant and that above all the occurrence of resistances in the paths within the apparatus, which can cause reaction pressures, is to be avoided . In particular, the feed pump must work without slippage. . The means by which the measurement is made can be seen in the drawing. A vessel is denoted by e, which is about half full with liquid. The bell f plunges into this, which is attached to the balance beam i, k, l by means of a stem h. The hollow body g serves to increase the buoyancy of the bell. The stalk h is passed through the cover of e with the stuffing box r.

Mittels der beiden Kapselpumpen d und d', welche miteinander gekuppelt sind, wird sowohl das Rauchgas als auch das Vergleichsgas (Luft) durch den Meßapparat gedrückt. Zur Erhöhung des hydrostatischen Druckes auf die beiden Kolbenflächen der Tauchglocke f sind mit den Hohlräumen e und e' über und unter dieser zwei Standrohre o und p verbunden, an deren oberen öffnungen die eingepumpten Gase austreten. Wird das leichte Gas unter und das schwere über die Tauchglocke geleitet, so sinkt diese näch unten und die Schreibfeder in zeichnet den Druckunterschied der beiden Gase auf der Registrierwalze st auf.By means of the two capsule pumps d and d ', which are coupled to one another, both the flue gas and the reference gas (air) are pressed through the measuring apparatus. In order to increase the hydrostatic pressure on the two piston surfaces of the diving bell f, two standpipes o and p are connected to the cavities e and e 'above and below the latter, at the upper openings of which the pumped-in gases emerge. If the light gas is passed under and the heavy gas over the diving bell, it sinks next and the pen in records the pressure difference between the two gases on the registration roller st.
