Description
Die Erfindung betrifft eine Vorrichtung zum Ermitteln der Zumischrate eines Zumischers entsprechend den Merkmalen des Oberbegriffes des ersten Patentanspruches und ein Verfahren nach den Merkmalen des Anspruches 7.
Die Erfindung ist geeignet, die Zumischrate des Schaummittels in einer Löschanlage mittels Zumischers zu ermitteln, ohne daß dabei ein umweltbelastendes Wasser-Schaum-Gemisch entsteht und entsorgt werden muß.The invention is suitable for determining the admixing rate of the foaming agent in an extinguishing system by means of Zumischers, without causing an environmentally harmful water-foam mixture and must be disposed of.
Das Schaummittel als Lagermedium in einem Membrantank ist eine wassergefährdende Flüssigkeit, die darüber hinaus Stoffe enthält, die schwer abbaubar sind. Bei der Inbetriebnahme und beim Testen eines Zumischers für ein Schaummittel aus einem Membrantank in einer Löschleitung muß das Schaum-Wasser-Gemisch aufgefangen, entsorgt und der Sondermüllentsorgung zugeführt werden, denn das Schaum-Wasser-Gemisch wird oft als wassergefährdende Flüssigkeit eingestuft und enthält schwer abbaubare Stoffe. Bei den zur Verfügung stehenden Zumischern ist es konstruktiv nicht möglich, das Schaummittel während des Zumischvorganges zu separieren und als reines Konzentrat aufzufangen, um es in den Schaummittelbehälter zurückzuführen. Membrantankzumischer werden bei einem Durchfluß von 500 I/mm nach VdS CEA 4001 (Teil M) bzw. bei minimalem und maximalem Durchflußwert mit Herstellung von Schaum-Wasser-Gemisch nach EN 13565-2 (11.3.2.4.2.) zur Ermittlung der Zumischrate getestet. Das Auffangen des Schaum-Wasser-Gemisches bei großen Durchflußwerten ist ausgesprochen schwierig, da es bei der Einleitung in einen Auffangbehälter zu erheblichen Verschäumungen kommt. Weiterhin müssen große Mengen Schaum-Wasser-Gemisch entsorgt werden. Bisher konnte die Zumischrate nur mittels des aufgefangenen Schaum-Wasser-Gemisches und Anmischen von weiteren drei Referenzlösungen über Leitfähigkeitsmeßgeräte oder Refraktometer ermittelt werden. Darüber hinaus wird das Ergebnis dieses Verfahrens durch eine Reihe von Einflußfaktoren beeinflußt, so daß es leicht zu ungenauen Meßwerten kommen kann.The foaming agent as storage medium in a membrane tank is a water-polluting liquid, which also contains substances that are difficult to decompose. When commissioning and testing a Zumischers for a foaming agent from a membrane tank in an extinguishing line, the foam-water mixture must be collected, disposed of and the special waste disposal, because the foam-water mixture is often classified as a water-polluting liquid and contains hardly degradable substances. With the available Zumischern it is structurally not possible to separate the foaming agent during the admixing process and collect as a pure concentrate to return it into the Schaummittelbehälter. Membrane tank mixers are used at a flow rate of 500 l / mm to VdS CEA 4001 (Part M) or at minimum and maximum flow value with production of foam-water mixture according to EN 13565-2 (11.3.2.4.2.) To determine the rate of addition tested. The capture of the foam-water mixture at high flow rates is very difficult, since it comes to the introduction into a collecting container to considerable foaming. Furthermore, large amounts of foam-water mixture must be disposed of. So far, the admixing rate could only be determined by means of the collected foam-water mixture and mixing of another three reference solutions via conductivity meters or refractometers. In addition, the result of this method is influenced by a number of influencing factors, so that it can easily lead to inaccurate readings.
Es ist daher Aufgabe der Erfindung, eine Vorrichtung und ein Verfahren zu entwickeln, mit dem es möglich ist, die Zumischrate eines Zumischers zwischen einem Membrantank und einer Löschleitung möglichst genau und zuverlässig zu ermitteln und einzustellen, ohne daß ein umweltbelastendes Wasser-Schaum-Gemisch entsteht und entsorgt werden muß.It is therefore an object of the invention to develop a device and a method with which it is possible to determine the rate of admixing of a Zumischers between a membrane tank and a discharge line as accurately and reliably as possible and set without an environmentally harmful water-foam mixture and must be disposed of.
Diese Aufgabe wird durch eine Vorrichtung nach den Merkmalen des ersten Patentanspruches und ein Verfahren nach Patentanspruch 7 gelöst.This object is achieved by a device according to the features of the first claim and a method according to
Unteransprüche geben vorteilhafte Ausgestaltungen der Erfinder wieder.Subclaims give advantageous embodiments of the inventors again.
Die erfindungsgemäße Vorrichtung zum Ermitteln der Zumischrate zwischen dem Schaumkonzentrat und dem Wasser eines Zumischers in einer Löschleitung und Leitungen und Armaturen zwischen dem Membrantank und dem Zumischer sieht vor, daß eine Testflüssigkeit in einer vom Wasser umgebenen Testmembrane angeordnet ist.The inventive device for determining the Zumischrate between the foam concentrate and the water of a Zumischers in an extinguishing line and lines and fittings between the membrane tank and the admixer provides that a test liquid is disposed in a test membrane surrounded by water.
Der Membranbehälter besteht aus einem Druckbehälter aus Stahl und einer innenliegenden flexiblen Membrane mit Form und Abmessung des Druckbehälters. Diese Ausführung bleibt unverändert.The membrane container consists of a pressure vessel made of steel and an internal flexible membrane with shape and dimensions of the pressure vessel. This version remains unchanged.
Es wird eine zweite Test-Membrane mit einem Fassungsvermögen für die Menge Testflüssigkeit, die ausreichend ist, den Test der Zumischrate durchzuführen, zwischen Schaummittelmembrane und Wandung des Druckbehälters montiert. Vorrichtungen zum Befüllen und zur Entnahme der Testflüssigkeit werden separat an der Außenwandung des Druckbehälters vorgesehen. Der Entnahmeanschluß wird unter Verwendung von Absperrarmaturen zum Umschalten zwischen Lösch- und Testbetrieb mit der Schaummittelkonzentratleitung, die zum Zumischer führt, verbunden. Die Dimension der Testleitung ist so zu wählen, daß sich keine Unterschiede bei den Druckverlusten im Lösch-und Testbetrieb ergeben. Optional kann ein Durchflußmesser in die Testleitung eingebunden werden.A second test membrane with a capacity for the amount of test liquid sufficient to perform the admixing rate test is mounted between the foam membrane and the wall of the pressure vessel. Devices for filling and for removing the test liquid are provided separately on the outer wall of the pressure vessel. The extraction port is connected to the foam concentrate line leading to the admixer using shut-off valves for switching between extinguishing and test operation. The dimension of the test line should be chosen so that there are no differences in the pressure losses in the erase and test mode. Optionally, a flowmeter can be integrated into the test line.
Als Testflüssigkeit wird eine nicht wassergefährdende, umweltverträgliche Flüssigkeit verwendet, die über das übliche Abwassersystem entsorgt werden kann. Die Dichte und Viskosität der Testflüssigkeit sollen denen des Schaummittels ähnlich sein. Weitere Anforderungen werden an die Testflüssigkeit nicht gestellt.As a test liquid, a non-water polluting, environmentally friendly liquid is used, which can be disposed of by the usual sewage system. The density and viscosity of the test fluid should be similar to those of the foaming agent. Further requirements are not imposed on the test liquid.
Der Test wird in folgender Weise ausgeführt: Der Membranbehälter ist mit Schaummittel befüllt. Das Schaummittel kann sich dabei innerhalb bzw. außerhalb der Hauptmembrane befinden. Es wird eine für die Durchführung des Tests ausreichende Menge Testflüssigkeit in die Test-Membrane gefüllt. Dafür ist ein geringer Überdruck erforderlich.The test is carried out in the following way: The membrane container is filled with foaming agent. The foaming agent may be located inside or outside the main membrane. A sufficient amount of test liquid is introduced into the test membrane to carry out the test. This requires a slight overpressure.
Die Test-Membrane mit der Testflüssigkeit ist zwischen der Wand des Membrantank und der Hauptmembrane angeordnet.The test membrane with the test liquid is placed between the wall of the membrane tank and the main membrane.
Schaummittelleitung und Testflüssigkeitsleitung zum Zumischer sind abgesperrt. Die Wasserversorgung der Löschanlage wird in Betrieb genommen. Es fließt ein bestimmterFoam conduit and test fluid line to the admixer are shut off. The water supply of the extinguishing system is put into operation. It flows a certain
Wasserstrom durch den Zumischer. Der Druck der Löschanlage wirkt über die wasserseitige Zuleitung auf den Membranbehälter. Die Absperrarmatur der Testleitung wird geöffnet. Der Anlagendruck drückt die Testmembrane zusammen und die Testflüssigkeit fließt zum Zumischer. Der Durchflußwert wird mittels Durchflußmesser in der Testleitung ermittelt. Aus dem Verhältnis Wasserdurchfluß und Testflüssigkeitsdurchfluß wird die tatsächliche Zumischrate ermittelt. Das Gemisch aus Löschwasser und Testflüssigkeit wird dem Abwassersystem über einem Testanschluß in der Löschleitung zugeleitet.Water flow through the admixer. The pressure of the extinguishing system acts on the water-side supply line to the membrane container. The shut-off valve of the test line is opened. The system pressure compresses the test membrane and the test fluid flows to the admixer. The flow rate is determined by means of flow meter in the test line. From the ratio of water flow and Testflüssigkeitsdurchfluß the actual rate of addition is determined. The mixture of extinguishing water and test liquid is fed to the sewage system via a test connection in the extinguishing line.
Vorteilhaft ist es in diesem Falle, ein Durchflußmeßgerät in der Testleitung anzuordnen.It is advantageous in this case to arrange a flowmeter in the test line.
Eine andere vorteilhafte Möglichkeit besteht darin, die Durchflußmenge über die Durchflußzeit der Testflüssigkeit zu messen. Daher wird die Menge Testflüssigkeit bestimmt, die in einer bestimmten Zeiteinheit (z. B. 30 sec) bei dem zu testenden Wasserdurchfluß zugemischt wird. Der Ablauf erfolgt wie bei der Ausführung mit dem Durchflußmeßgerät, jedoch wird statt des Durchflußmessers ein Schauglas installiert. Am Schauglas wird die Zeit vom Start bis zum Ende des Fließens der der Testflüssigkeit ermittelt. Die Zumischrate wird über das Verhältnis der Mengen Wasser und Testflüssigkeit in einer bestimmten Zeiteinheit berechnet.Another advantageous possibility is to measure the flow rate over the flow time of the test liquid. Therefore, the amount of test liquid to be mixed in a certain time unit (for example, 30 seconds) at the water flow to be tested is determined. The procedure is the same as in the version with the flow meter, but instead of the flow meter, a sight glass is installed. On the sight glass, the time from the start to the end of the flow of the test liquid is determined. The admixing rate is calculated by the ratio of the quantities of water and test liquid in a specific time unit.
Eine andere vorteilhafte Lösungsvariante sieht vor, eine Test-Membrane und eine Testflüssigkeit in einem separaten Behälter anzuordnen.Another advantageous solution variant provides for arranging a test membrane and a test liquid in a separate container.
Der Test-Membranbehälter hat die Größe der benötigten Testflüssigkeitsmenge und ist komplett mit Testflüssigkeit gefüllt. Der wasserseitige Anlagendruck wird über eine von der Wasserzuleitung zum Membranbehälter abzweigenden Leitung mit Armatur auf den Test-Membranbehälter gegeben.The test membrane container has the size of the required test liquid and is completely filled with test liquid. The water-side system pressure is given to the test membrane container via a line with armature branching off from the water supply line to the membrane container.
Durch die Erfindung wird die sonst erforderliche Entsorgung von wassergefährdendem und umweltbelastendem Schaum-Wasser-Gemisch vermieden. Bisher fielen bei jedem Test 1.000 - 2.00 Liter Schaum-Wasser-Gemisch an. Das bisherige Verfahren ist besonders hinsichtlich des Auffangens von Schaum-Wasser-Gemisch mit einem Durchfluß von mindestens 500 I/min äußerst umständlich und risikoreich. Es können sehr starke Verschäumungen entstehen, Schaum unkontrolliert überlaufen und Umweltschäden entstehen. Dies entfällt durch Verwendung einer unkritischen Testflüssigkeit. Die Erfindung macht die Verwendung einer Testflüssigkeit möglich.By the invention, the otherwise necessary disposal of water polluting and polluting foam-water mixture is avoided. So far, each test produced 1,000 - 2.00 liters of foam-water mixture. The previous method is extremely cumbersome and risky, especially with regard to the collection of foam-water mixture with a flow rate of at least 500 l / min. It can cause very strong foaming, foam overflow uncontrolled and environmental damage. This is eliminated by using a non-critical test liquid. The invention makes possible the use of a test liquid.
Die Ermittlung der Zumischrate ist durch viele Einflußfaktoren und Fehlerquellen nur von erfahrenen, geübten Personen sicher durchzuführen. Mit der Erfindung ist die Ermittlung der Zumischrate einfacher, genauer und sicherer durchführbar.The determination of the admixing rate is to be carried out by many influential factors and sources of error only by experienced, experienced persons. With the invention, the determination of the Zumischrate is easier, more accurate and safer to carry out.
