Description

Verfahren zur Bestimmung des Staubgehalts von Gasen. Brennende Gase, z. B. Hochofengichtgas, verändern die Farbe ihrer Flamme entsprechend dem Staubgehalt. So brennen z. B. staubhaltige Hochofengase dunkelrot, während die Flamme mit zunehmender Reinheit des Gases allmählich eine klare blaue Farbe annimmt.Method for determining the dust content of gases. Burning gases, z. B. blast furnace top gas, change the color of their flame according to the dust content. So burn z. B. dusty blast furnace gases dark red, while the flame with increasing Purity of the gas gradually turns a clear blue color.

Um den Staubgehalt solcher Gase festzustellen, hat man die Trübung der durch derartige Gase hindurchgegangenen Strahlen einer besonderen Lichtquelle bestimmt.In order to determine the dust content of such gases, one has the turbidity the rays of a particular light source which have passed through such gases certainly.

Es ist bei der Bestimmung abziehender Rauchgase ferner bekannt, die durch den Rauch getrübten Lichtstrahlen einer besonderen Lichtquelle auf einen Selenwiderstand fallen zu lassen und aus dessen Widerstandsänderung die Rauchstärke zu bestimmen. Demgegenüber werden gemäß vorliegender Erfindung die Strahlen der Flamme des auf seinen Staubgehalt zu untersuchenden Gases unmittelbar oder mittelbar auf eine Selenzelle gerichtet, die in bekannter Weise mit einem Stromerzeuger (Batterie) und einem Meßinstrument mit entsprechend geeichter Skala in einem Stromkreis liegt.It is also known in the determination of exhaust gases that Light rays clouded by the smoke from a special light source on a selenium resistor to drop and to determine the smoke strength from its change in resistance. In contrast, according to the present invention, the rays of the flame of the its dust content of the gas to be examined directly or indirectly on a selenium cell directed in a known manner with a power generator (battery) and a measuring instrument is in a circuit with a correspondingly calibrated scale.

Die Zeichnung zeigt eine Ausführungsform des neuen Verfahrens.The drawing shows an embodiment of the new method.

Der Gasbrenner a (z. B. Bunsenbrenner) ist an die Gasleitung, durch welche das zu untersuchende Gas fließt, angeschlossen. Das Gas brennt mit einer Flamme b im Gehäuse c. Die Strahlen der Flamme b fallen durch die öffnung d und die Sammellinse e auf die Selenzelle b, die in dem Stromkreis g liegt. In diesen Stromkreis ist noch die Stromquelle 7a und das elektrische Meßinstrument i eingeschaltet. Je nach der Stärke der Strahlen der Flamme b, d. h. je nach der dem Staubgehalt entsprechenden Farbe der Flamme, wird die Leitfähigkeit der Selenzelle f zu- oder abnehmen, was an dem Zeigerausschlag des Instrumentes i festzustellen ist.The gas burner a (e.g. Bunsen burner) is connected to the gas line which flows the gas to be examined, connected. The gas burns with one Flame b in the housing c. The rays of the flame b fall through the opening d and the converging lens e on the selenium cell b, which is in the circuit g. In these Circuit is still the power source 7a and the electrical measuring instrument i switched on. Depending on the strength of the rays of the flame b, d. H. depending on the dust content corresponding color of the flame, the conductivity of the selenium cell f increases or take off what can be determined from the pointer deflection of the instrument i.

Die Instrumentenskala kann entsprechend geeicht werden, so daß der jeweilige Staubgehalt abgelesen und gegebenenfalls selbsttätig und fortlaufend aufgezeichnet werden kann, wie aus dem auf der Zeichnung dargestellten Registrierinstrument zu ersehen ist.The instrument scale can be calibrated accordingly so that the respective dust content read off and, if necessary, automatically and continuously recorded can be, as from the recording instrument shown in the drawing is seen.

Durch Anbringung eines geeigneten Kontaktes am Instrument kann der Zeiger bei zu hohem Staubgehalt des Gases ein Relais betätigen, wodurch entweder eine Alarmvorrichtung in Bewegung gesetzt wird, welche die Bedienungsmannschaft aufmerksam macht, oder es kann durch dieses Relais eine mechanische Reguliervorrichtung in Tätigkeit gesetzt werden.By attaching a suitable contact to the instrument, the If the dust content of the gas is too high, the pointer actuates a relay, whereby either an alarm device is set in motion, which the operating crew or it can be a mechanical regulating device through this relay be put into action.
