Description
Vorichtung zur Bestimmung des Staubgehaltes in strömenden Gasen Die Erfindung betrifft eine Vorrichtung zur Bestimmung des Staubgehaltes in strömenden Gasen unter Verwendung einer regenerierungsfähigen Filterpatrone aus porösem Material für normale und heiße Gase Bekannt sind Vorrichtungen zur Bestimmung des Staubgehaltes in strömenden Gasen, die jedoch fast ausschließlich ein Filtermedium zur Abscheidung des im Gas befindlichen Staubes besitzen, welches nach Jeder Messung erneuert werden muß.Device for determining the dust content in flowing gases The invention relates to a device for determining the dust content in flowing Gases using a regenerable filter cartridge made of porous material for normal and hot gases Devices for determining the dust content are known in flowing gases, which, however, are almost exclusively a filter medium for separation of the dust in the gas, which is renewed after each measurement got to.
Außerdem haftet den meisten Geräten der Nachteil an, daß sie nur in einem eng begrenzten Temperaturbereich funktionssicher arbeiten können und demzufolge größtenteils nur als Außenfiltergeräte Anwendung finden [1,2,3,4,5,6]. Der Nachteil der Außenfilter ist hinreichend genug bekannt und soll nicht näher erläutert werden. Innenfiltergeräte [1,2] haben sich ebenfalls durchsetzen können, ihr weiterer Einsatz scheiterte meist an der Temperaturgrenze des Filtermediums.In addition, most devices have the disadvantage that they can only be used in can work reliably in a narrowly limited temperature range and consequently mostly only used as external filter devices [1,2,3,4,5,6]. The disadvantage the external filter is sufficiently well known and should not be explained in more detail. Internal filter devices [1,2] have also been able to establish themselves, their further use mostly failed due to the temperature limit of the filter medium.
Bisher eingesetzte temperaturbeständige Filtermedien hatten einmal den Nachteil, daß der abgeschiedene Staub nicht oder stark fehlerbehaftet für eine Korngrößenanalyse verwendet werden konnte, zum anderen war das verwendete Filtermedium stark bruchempfindlich und somit für weitere Messungen nicht einsetzbar.Previously used temperature-resistant filter media had once the disadvantage that the deposited dust is not or very flawed for a Particle size analysis could be used, on the other hand was the filter medium used strong fragile and therefore not usable for further measurements.
Der Zweck der Erfindung besteht darin, die geschildertBn Nachteile von Vorrichtungen zur Bestimmung des Staubgehaltes in strömenden Gasen, insbesondere für normale und hohe dem peraturen, zu beheben.The purpose of the invention is to overcome the disadvantages outlined of devices for determining the dust content in flowing gases, in particular for normal and high temperatures, to fix.
Der Erfindung liegt die Aufgabe zu Gruride, eine Vorrichtung zu schafen, die eine Bestimmung des Staubgehaltes in strömenden Gasen bei normalen und hohen Abgastemperaturen ermöglicht und eine ausreichende Regenerierung des Filtermediums zuläßt.The invention is based on the task of Gruride to create a device one determination of the dust content in flowing gases at normal and high Allow exhaust gas temperatures and sufficient regeneration of the filter medium allows.
Erfindungsgemäß ist die Aufgabe dadurch gelöst, daß ein an sich bekanntes Innenf ilt ermeß gerät mit einer Filt erpatrone aus porösem Material verwendet wird, welche für normale wie auch für hohe Temperaturen einsatzfähig ist.According to the invention, the object is achieved in that a known per se Internal filter measuring device with a filter cartridge made of porous material is used, which can be used for normal as well as for high temperatures.
Zur Senkung der Bruchempfindlichkeit der Filterpatrone und Gewährleistung einer vollständigen Dichtheit wird die Filterpatrone mit einer Buchse aus temperaturbeständigem und bruchfestem Material fest verbunden.To reduce the sensitivity of the filter cartridge to breakage and to guarantee A complete tightness is the filter cartridge with a bushing made of temperature-resistant and break-proof material firmly connected.
Der be der Bestimmung des Staubgehaltes in strömenden Gasen anfallende und von der Filterpatrone zurückgehaltene Staub kann durch leichtes Klopfen herausgelöst werden. Eine restlose Regenerierung erfolgt anschließend durch entgegengesetztes Durchblasen mit Druckluft bzw. Durchströmen von Wasser.The amount that occurs when determining the dust content in flowing gases and dust retained by the filter cartridge can be removed by lightly tapping it will. A complete regeneration is then carried out by doing the opposite Blowing through with compressed air or flowing through with water.
Die Erfindung soll nachstehend an einem Ausführungsbeispiel näher erläutert werden. In der zugehörigen Zeichnung zeigt Big. 1: die Vorderansicht der Vorrichtung als Schnitt.The invention is to be described in more detail below using an exemplary embodiment explained. In the accompanying drawing, Big. 1: the front view of the Device as a cut.
Die Vorrichtung besteht aus einer an sich bekannten Absaugsonde 1, dem Rohrstück 2 sowie dem Aufnahmekopf 3 für die Filterpatrone 4. Das Entnahmerthr 5 dient zum vollständigen Dichtschließen der Filterpatrone 4 mit dem Aufnahmekopf 3.The device consists of a suction probe 1 known per se, the pipe section 2 and the receiving head 3 for the filter cartridge 4. The removal tube 5 is used to completely seal the filter cartridge 4 with the receiving head 3.
Das Festklemmen der mit der Filterpatrone 4 fest verbundenen bruchfesten und temperaturbeständigen Buchse 6 bewirkt eine hohe Haltbarkeit des Filtermediums sowie infolge ständiger Regenerierungsfähigkeit eine Wiederverwendung Der yom Hauptgasstrom kontinuierlich und isokinetisch abgesaugte staubbeladene Teilgasstrom strömt durch die Absaugsonde 1 und das Rohrstück 2 über den Aufnahmekopf 3 in die Filterpatrone 4, in welcher der Staub nahezu hundertprozentig zurückgehalten wird0 Das gereinigte Gas wird von einem druckluftbetriebenen Ejektor mit Mavaldüse 9 über die Temperaturmeßstrecke 7 mit Drosseleinrichtung 8 angesaugt und ins Freie bzw zurück in den Hauptgasstrom gedrückt. Die Aneinanderreihung der einzelnen Geräteteile durch schnelllösende Verschraubung unter Beibehaltung eines gleichen Außendurchmessers zur Abtastung des gesamten Hauptstromquerschnittes macht die Vorrichtung zur Bestimmung des Staubgehaltes in strömenden Gasen zu einer komplexen MeB-einrichtung.The clamping of the break-proof firmly connected to the filter cartridge 4 and temperature-resistant bush 6 causes a high durability of the filter medium as well as a reuse of the main gas flow due to the constant regenerative capacity Continuously and isokinetically extracted, dust-laden partial gas stream flows through the suction probe 1 and the pipe section 2 via the receiving head 3 into the filter cartridge 4, in which the dust is retained almost one hundred percent0 The cleaned Gas is fed from an ejector operated by compressed air with a Maval nozzle 9 over the temperature measuring section 7 sucked in with throttle device 8 and into the open air or back into the main gas flow pressed. The stringing together of the individual device parts by means of quick-release screw connections while maintaining the same outer diameter for scanning the entire main flow cross-section makes the device for determining the dust content in flowing gases one complex measuring device.
Die Vorteile der in der Erfindung dargelegten Vorrichtung lassen sich wie folgt zusammenfassen: - Wegfall der Staubverluste in der Entnahmeleitung und im Schlauch bei Außenfiltergeräten - Geringe Masse gegenüber bekannten Außen- und Innenfilt ermeßgeräten - Ständige Wiederverwendung der Filterpatronen infolge Regenerierbarkeit Durch die komplexe Meßeinrichtung ist eine einfache Handhabung der Vorrichtung gegeben - Gewährleistung einer einwandfreien Körnungsanalyse des zurückgewonnenen Staubes durch vollständiges Herauslösen des Staubes aus der Filterpatrone.The advantages of the device set out in the invention can be summarize as follows: - Elimination of dust losses in the extraction line and in the hose of external filter devices - Low mass compared to known ones External and internal filter gauges - constant reuse of the filter cartridges due to regenerability The complex measuring device makes it easy to use given to the device - ensuring a proper grain analysis of the recovered dust by completely removing the dust from the filter cartridge.
