Abstract
Description
Die Erfindung betrifft ein Verfahren zur Feststellung des Verschmutzungsgrades eines Reinigungselementes, insbesondere eines Filters oder Abscheiders, insbesondere eines Gasfilters, bei dem die für die Erkennung des Verschmutzungsgrades notwendigen Größen, wie z. B. der absolute Gasdruck, der Differenzdruck und der Gas durchsatz gemessen werden.The invention relates to a method for determining the Degree of contamination of a cleaning element, in particular a filter or separator, especially one Gas filter, in which the for the detection of the Pollution levels necessary sizes, such as. B. the absolute gas pressure, the differential pressure and the gas throughput can be measured.
Die in strömenden Medien erhaltenen Fremdkörper werden bekanntlich mit Hilfe von Filterelementen beseitigt. Das hat zur Folge, daß mit der Zeit der Filter verschmutzt. Dabei ist ein gewisser Verschmutzungsgrad des Filters zulässig. Erreicht der Filter jedoch einen zu hohen Verschmutzungsgrad, dann muß er ausgewechselt werden, weil sonst der Differenzdruck d. h. der Druck vor in Vergleich hinter dem Filter so hoch werden könnte, daß Beschädigungen eintreten können.The foreign bodies obtained in flowing media become known to be eliminated with the help of filter elements. That has with the result that the filter becomes dirty over time. It is a certain degree of contamination of the filter is permitted. However, if the filter gets too dirty, then it must be replaced, otherwise the Differential pressure d. H. the pressure before compared behind the Filters could become so high that damage occurs can.
Daher ist es erforderlich, den Verschmutzungsgrad des Filters zu überwachen.It is therefore necessary to determine the degree of contamination of the filter to monitor.
Der Filter befindet sich dabei in einem Behälter. Die Messung des Differenzdruckes wird dabei in der Weise vorgenommen, daß der Druck am Gehäuseeingang und der Druck am Gehäuseausgang gemessen und die gemessenen Werte miteinander verglichen werden.The filter is in a container. The measurement the differential pressure is carried out in such a way that the pressure at the housing inlet and the pressure at the housing outlet measured and the measured values compared will.
Dabei besteht ein Zusammenhang zwischen dem Gasdurchsatz und dem Differenzdruck. Wird der Differenzdruck bei einem bestimmten Gasdurchsatz immer größer, dann ist das ein Zeichen dafür, daß der Filter immer mehr verschmutzt. Man kann nun anhand eines Diagrammes die zu dem maximalen Gasdurchsatz gehörigen Differenzdruckwerte feststellen. Wird ein bestimmter hoher Differenzdruckwert gemessen, dann ist das ein Zeichen für einen hohen Verschmutzungsgrad. There is a relationship between the gas flow and the differential pressure. If the differential pressure at a certain gas flow ever larger, then that's one Signs that the filter is becoming more and more dirty. Man can now use a diagram to determine the maximum Determine the differential pressure values associated with the gas flow. Becomes a certain high differential pressure value is measured, then which is a sign of a high degree of pollution.
Diese Art der Feststellung des Verschmutzungsgrades ist jedoch nicht absolut zuverlässig.This is how the level of pollution is determined but not absolutely reliable.
Wird nämlich das Filtergehäuse von einer Teilmenge des Gasstromes durchströmt, dann sinkt der Differenzdruck überproportional ab. Man erhält so Differenzdruckwerte, die den Eindruck vermitteln, als ob der Filter noch nicht besonders stark verschmutzt sei, obwohl in der Tat das Gegenteil der Fall ist.If the filter housing of a subset of Flows through the gas stream, then the differential pressure drops disproportionately. This gives differential pressure values that give the impression as if the filter has not yet is particularly heavily polluted, although in fact it is The opposite is the case.
Daraus folgt, daß eine von Zeit zu Zeit erfolgte Messung des Differenzdruckes zum Zwecke der Überprüfung des Verschmutzungsgrades des Filters zu völlig falschen Ergebnissen führen kann.It follows that a measurement of the Differential pressure for the purpose of checking the Degree of contamination of the filter to completely wrong Results.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zur Feststellung des Verschmutzungsgrades eines Reinigungs elementes, insbesondere eines Gasfilters, zu schaffen, bei dem mit Sicherheit der höchst zulässige Verschmutzungsgrad festgestellt werden kann.The invention is therefore based on the object of a method to determine the degree of contamination of a cleaning element, in particular a gas filter, to create which is certainly the highest permissible level of pollution can be determined.
Das wird erfindungsgemäß dadurch erreicht, daß die für die Erkennung des Verschmutzungsgrades notwendigen Größen, wie z. B. Gasdruck, Differenzdruck und der Gasdurchsatz dauernd gemessen werden und die durch die Messung dieser Größen ausgelösten elektrischen Impulse in einen Rechner eingegeben werden.This is achieved in that the for Detection of the degree of pollution necessary sizes, such as e.g. B. gas pressure, differential pressure and gas throughput continuously be measured and that by measuring these quantities triggered electrical impulses entered into a computer will.
Durch die dauernde Messung der für den Verschmutzungsgrad maßgeblichen Werte und die Eingabe in den Rechner ist erreicht, daß schon dann, wenn der Filter erstmalig seinen vollen Verschmutzungsgrad erreicht hat, der Rechner dieses anzeigt. By continuously measuring the level of pollution relevant values and the input into the calculator achieved that when the filter was first used the computer has reached this level of contamination displays.
Die bei den bekannten Meßmethoden bestehende Gefahr, nämlich daß trotz eines hundertprozentig verschmutzten Filters infolge des überproportional absinkenden Differenzdruckes bei Teilmengen ein falscher Verschmutzungsgrad angezeigt wird, ist damit vermieden.The existing danger with the known measuring methods, namely that despite a 100% dirty filter as a result of the disproportionately lower differential pressure An incorrect degree of contamination is displayed is avoided.
Das Blockschaltbild zeigt den grundsätzlichen Aufbau des erfindungsgemäßen Verfahrens.The block diagram shows the basic structure of the inventive method.
Mit 1 ist der Gasfilter bezeichnet, der den Eingang 2 und den Ausgang 3 aufweist. Der Differenzdruck zwischen der Eingangsseite und der Ausgangsseite wird mit Hilfe des Differenzdruckmessers 4 gemessen. Der absolute Gasdruck des Gasstromes und der Gasdurchsatz wird durch entsprechende Meßinstrumente gemessen, deren Werte einem Transmitter 5 bzw. 6 übermittelt werden, welche die gemessenen Größen in elektrische Analogsignale umwandeln, und diese dann über entsprechende Trennstufen 7, 8 und 9 dem Rechner 10 zugeführt werden. 1 designates the gas filter which has input 2 and output 3 . The differential pressure between the input side and the output side is measured using the differential pressure meter 4 . The absolute gas pressure of the gas flow and the gas throughput is measured by appropriate measuring instruments, the values of which are transmitted to a transmitter 5 or 6 , which convert the measured quantities into electrical analog signals, and these are then fed to the computer 10 via corresponding isolating stages 7, 8 and 9 .
Der Rechner zeigt den Verschmutzungsgrad in Prozent an. Dabei kann der Rechner so ausgebildet sein, daß bei einem Verschmutzungsgrad von 70% ein erstes Signal, beispielsweise ein akustisches Signal, und bei 100%iger Verschmutzung ein weiteres akustisches Signal gegeben wird. Des weiteren ist der Rechner mit einem analogen Ausgangssignal I, das eine Fernübertragung des Verschmutzungsgrades ermöglicht, versehen, ferner mit einem Ausgangssignal II, welches eine beispielsweise 70%ige Verschmutzung anzeigt, und mit einem Ausgangssignal III, das eine 100%ige Verschmutzung angibt.The calculator shows the degree of contamination in percent. Here the computer can be designed so that at a Degree of contamination of 70% a first signal, for example an acoustic signal, and when there is 100% contamination further acoustic signal is given. Furthermore is the Computer with an analog output signal I, the one Remote transmission of the degree of pollution enables provided, further with an output signal II, which a for example, indicates 70% pollution, and with a Output signal III, which indicates 100% contamination.
