Description
Die Erfindung betrifft eine Vorrichtung zum Bestimmen des Rußgehalts von Rauchgasen laut Oberbegriff des Patentanspruches.The invention relates to a device for determining the soot content of flue gases according to the preamble of the patent claim.
Vorrichtungen dieser Art sind bekannt (AT-PS 2 67 232). Die Genauigkeit der Messung hängt im wesentlichen davon ab, daß über die Kolbenpumpe stets eine gleichgroße Rauchgasmenge entnommen wird. Hierbei haben verschiedene Faktoren einen Einfluß, beispielsweise die Gastemperatur, die Sauggeschwindigkeit, die Wartezeiten zwischen aufeinanderfolgenden Ansaugvorgängen, orts- und zeitabhängige Unterschiede des atmosphärischen Druckes usw.Devices of this type are known (AT-PS 2 67 232). The accuracy of the measurement depends on the essentially depends on the fact that an equal amount of smoke gas is always withdrawn via the piston pump. Various factors have an influence here, for example the gas temperature, the suction speed, the waiting times between successive suction processes, location and time-dependent differences atmospheric pressure etc.
Es ist Aufgabe der Erfindung, die Meßgenauigkeit einer Vorrichtung der eingangs erwähnten Art zu verbessern.It is the object of the invention to improve the measurement accuracy to improve a device of the type mentioned.
Diese Aufgabe wird ausgehend von einer Vorrichtung laut Oberbegriff des Patentanspruches durch dessen kennzeichnende MerKmale gelöst.This task is based on a device according to the preamble of the claim by the characteristic features solved.
Bei der erfindungsgemäßen Vorrichtung wird der Hub der die Rauchgasmenge durch das Filter ansaugenden Kolbenpumpe in Abhängigkeit Dn eventuellen Temperatur- oder Druckänderungen so gesteuert, daß stets eine konstante Menge von Rauchgas durch das Filter hindurchgeführt wird, also bei aufeinanderfolgenden Messungen die Gasmenge stets konstant bleibt Damit sind mit einer solchen Vorrichtung wesentlich genauere Rauchdichtebestimmungen möglich.In the device according to the invention is the Stroke of the piston pump sucking in the amount of flue gas through the filter as a function of the eventual Dn Changes in temperature or pressure controlled so that a constant amount of flue gas through the Filter is passed through, so the amount of gas always remains constant with successive measurements With such a device, significantly more precise smoke density determinations are possible.
Die Erfindung wird im folgenden anhand einer schematischen Zeichnung an einem Ausführungsbeispiel näher erläutertThe invention is illustrated below with the aid of a schematic drawing of an exemplary embodiment explained in more detail
Die Figur zeigt den Prinzipaufbau einer selbsttätig arbeitenden Vorrichtung zum Bestimmen des Rußgehaltes von Rauchgasen durch Bestimmung der Schwärzung eines Filters. Die dargestellte Vorrichtung besteht aus einem Filter 1, das beispielsweise in einem entsprechenden Filterhalter durch eine geeignete selbsttätige Einrichtung zum Einlegen des Filterpapiers angeordnet ist, einer zugeordneten Vorrichtung 2 zum selbsttätigen Bestimmen der Schwärzung des Filters, die in dem gezeigten Ausführungsbeispiel mit Betastrahlen arbeitet, sowie einer Kolbenpumpe 3. die über ein Dreiwegeventil 4 eine vorbestimmte Rauchgasmenge durch das Filter 1 ansaugt Der Kolben 5 der Kolbenpumpe 3 ist über einen Motor 6 hin- und herverschiebbar. Zu einer Rußgehaltmessung werden die einzelnen Bestandteile der Vorrichtung über eine schematisch angedeutete programmierbare Steuervorrichtung 7 in bekannter Weise gesteuert Zusätzlich ist noch eine Vorrichtung 8 zum Messen der Temperatur und des Druckes vorgesehen, die außerdem elektronische Schaltkreise enthält, über die mittels eines Servomotors 9 ein längs der Kolbenbetätigungsstange 10 angeordneter Hubbegrenzungsschalter 11 in Abhängigkeit von der Temperatur- und Druckmessung verstellbar ist Bei Temperatur- und Druckänderungen wird über den Servomotor 9 der Schalter 11 längs des Hubweges der Kolbenstange 10 entsprechend verstellt, und über den Schalter 11, der mit einem entsprechenden Anschlag 12 der Kolbenstange zusammenarbeitet wird auf diese Weise temperatur- und druckabhängig der Saughub der Kolbenpumpe 3 entsprechend verstellt, so daß sich eine für die Messung konstante Rauchgasmengenansaugung ergibtThe figure shows the basic structure of an automatically operating device for determining the soot content of flue gases by determining the blackening of a filter. The device shown consists of a filter 1, which is arranged, for example, in a corresponding filter holder by a suitable automatic device for inserting the filter paper, an associated device 2 for automatically determining the blackening of the filter, which works with beta rays in the embodiment shown, and a Piston pump 3. Which sucks in a predetermined amount of smoke gas through the filter 1 via a three-way valve 4. The piston 5 of the piston pump 3 can be pushed back and forth by a motor 6. To a Rußgehaltmessung the individual components of the device are controlled in known manner via a schematically indicated programmable control device 7. In addition, a device 8 is also provided for measuring the temperature and pressure, contains further electronic circuits, on a longitudinally by a servomotor 9 of the Piston operating rod 10 arranged stroke limit switch 11 is adjustable depending on the temperature and pressure measurement. In the event of temperature and pressure changes, the servomotor 9 of the switch 11 along the stroke of the piston rod 10 is adjusted accordingly, and via the switch 11, which with a corresponding stop 12 of the The piston rod works together in this way, depending on temperature and pressure, the suction stroke of the piston pump 3 is adjusted accordingly, so that a constant amount of smoke gas suction results for the measurement
Das Dreiwegeventil 4 ist ebenfalls über einen Servomotor gesteuert und zwar so, daß beim Ansaugen das Rauchgas durch den Filter 1 h'indurchgesaugt wird, nach einer Messung das Gas jedoch unmittelbar aus der Kolbenpumpe 3 nach außen abgeführt wird.The three-way valve 4 is also controlled by a servo motor in such a way that during suction the flue gas through the filter 1 h'indu r chgesaugt is, after a measurement, the gas is, however, immediately discharged from the piston pump 3 to the outside.
