Description

Die Erfindung betrifft eine Vorrichtung zum Ermitteln der Zumischrate eines Membrantank-Zumischers entsprechend den Merkmalen des Oberbegriffes des ersten Patentanspruches.The invention relates to a device for determining the Zumischrate a membrane tank Zumischers according to the features of the preamble of the first claim.

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 und ohne, daß eine Ersatzflüssigkeit eingesetzt 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 is formed and disposed of and without that a replacement liquid must be used.

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 l/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 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. Membrantankzumischer be 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.) For determining 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 inaccurate measured values can occur.

Es ist daher Aufgabe der Erfindung, eine Vorrichtung zu entwickeln, mit dem es möglich ist, die Zumischrate eines Zumischers 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 with which it is possible to determine the Zumischrate Zumischers an extinguishing line as accurately and reliably as possible and set without an environmentally polluting water-foam mixture is created and disposed of.

Diese Aufgabe wird durch eine Vorrichtung nach den Merkmalen des ersten Patentanspruches gelöst.This object is achieved by a device according to the features of the first claim.

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 sieht vor, daß in einfachster Weise zur Realisierung der Erfindung zwischen der Löschleitung und dem Zumischer eine Leitung angeordnet ist, in der sich ein Schaummittel-Äquivalentventil befindet und ein Gerät zur Durchflußmessung. Die Leitung zwischen Löschleitung und Zumischer wird im Folgenden als Bypassleitung bezeichnet. In ihr kann eine Absperrarmatur vorhanden sein, um sie von der Löschleitung zu trennen. Als Gerät zur Durchflußmessung wird ein dem Fachmann bekanntes Durchflußmeßgerät verwendet.The device according to the invention for determining the admixing rate between the foam concentrate and the water of a Zumischers in an extinguishing line provides that in the simplest manner for realizing the invention between the extinguishing pipe and the Zumischer a line is arranged, in which a foaming agent equivalent valve is located and a Device for flow measurement. The line between the extinguishing line and the admixer is referred to below as the bypass line. In it, a shut-off valve may be present to separate them from the extinguishing pipe. As a flow meter, a flow meter known to those skilled in the art is used.

Vorteilhaft ist es, die Bypassleitung zwischen der Leitung anzuordnen, die das Wasser in den Membrantank leitet und zu der Leitung führt, die den Membrantank mit einem SchaumKonzentrat wieder verläßt. Dabei ist es vorteilhaft, 3/2-Wege-Absperrarmaturen vor und nach dem Membrantank anzuordnen.It is advantageous to arrange the bypass line between the line, which directs the water in the membrane tank and leads to the line that leaves the membrane tank with a foam concentrate again. It is advantageous to arrange 3/2-way shut-off valves before and after the membrane tank.

Bei dem Membrantank handelt es sich um einen üblichen Membrantank, welcher eine Membrane zwischen Wasser und Schaumkonzentrat aufweist und in den ein Steigrohr hineinragt, durch den das Schaumkonzentrat den Membranktank verläßt.The membrane tank is a conventional membrane tank, which has a membrane between water and foam concentrate and into which protrudes a riser through which the foam concentrate leaves the membrane tank.

Das Schaummittel-Äquivalentventil in der Bypassleitung stellt in vorteilhafter Weise ein Drosselventil dar, an dem eine Einstellanzeige angeordnet ist.The foaming agent equivalent valve in the bypass line is advantageously a throttle valve on which an adjustment display is arranged.

Bei der Inbetriebnahme und dem Testen der Zumischrate fließt das Löschwasser nicht in den Membranbehälter, sondern durch die Test-Bypassleitung, Es wird kein Schaummittel zugemischt, stattdessen mischt der Zumischer das Wasser der Bypassleitung zu. Aufgrund der unterschiedlichen Dichte und Viskosität würde bei dem Durchfluß von Wasser durch die Test-Bypassleitung eine andere Durchflußmenge gemessen werden als beim Betrieb der Zumischeinrichtung mit Schaumkonzentrat im Löschfall. Diese Abweichungen des Meßergebnisses werden durch entsprechende Regulierung des Schaummitteläquivalentventils kompensiert. Es wird ein größerer Druckverlust im Wasserbetrieb erzeugt, um mit Wasser den Durchfluß zu erzeugen, der sich mit Schaummittel einstellen würde.During commissioning and testing of the admixing rate, the extinguishing water does not flow into the membrane container, but through the test bypass line. No foaming agent is mixed in, instead the admixer mixes the water to the bypass line. Due to the different density and viscosity would be measured at the flow of water through the test bypass line, a different flow rate than when operating the admixing with foam concentrate in case of fire. These deviations of the measurement result are compensated by appropriate regulation of the foaming agent equivalent valve. There is a greater pressure drop in the water operation is generated to produce the flow of water, which would adjust with foaming agent.

Das Schaummittel-Äquivalentventil wird im Zuge der Produktentwicklung mittels Berechnung der tatsächlichen Druckverluste mit Schaummittel bzw. mittels Vergleichsmessungen in Versuchen mit Schaummitteldurchfluß auf die verschiedenen Schaummitteltypen ähnlicher Viskosität kalibriert. Dabei muß der Durchfluß durch den Zumischer mit einbezogen werden, da in der Regeleinheit des Zumischers konstruktionsbedingt deutliche Druckverluste aufweist und ein Außerachtlassen unzulässige Verfälschung der ermittelten Zumischrate zur Folge hätte. Das Schaummittel-Äquivalentventil weist Markierungen auf, mit denen der äquivalente Druckverlust für Wasser von verschieden Schaummitteltypen eingestellt werden kann.The foaming agent equivalent valve is calibrated in the course of product development by calculating the actual pressure losses with foaming agent or by means of comparative measurements in tests with foam medium flow on the different foaming agent types of similar viscosity. In this case, the flow through the admix must be included, as in the control unit of the Zumischers by design has significant pressure losses and a disregarding excessive distortion of the determined Zumischrate would result. The foaming agent equivalent valve has markings with which the equivalent pressure loss for water of different types of foaming agent can be adjusted.

Für den Test der Zumischrate werden die 3/2-Wege-Absperrrarmaturen in Richtung Bypassleitung gestellt, das Schaummitteiäquivalentventil auf das verwendete Schaummittel eingestellt, die Löschanlage wird in Testbetrieb genommen und der Durchflußwert wird an dem Meßgerät abgelesen. Mit diesem Wert kann mit bekannter Formel die Zumischrate berechnet werden.For the test of Zumischrate the 3/2-way shut-off valves are set in the direction of the bypass line, the Schaummitteiäquivalentventil set to the foaming agent used, the extinguishing system is put into test mode and the flow rate is read on the meter. This value can be used to calculate the proportioning rate using a known formula.

Weiterhin ist es vorteilhaft, Entleervorrichtungen an der erfindungsgemäßen Vorrichtung anzuordnen. Das sind Absperrventile, unter denen sich ein Abfluß befindet. Weiterhin ist es vorteilhaft, die Druckarmaturen in den Leitungen der Anlage anzuordnen.Furthermore, it is advantageous to arrange emptying devices on the device according to the invention. These are shut-off valves, under which there is a drain. Furthermore, it is advantageous to arrange the pressure fittings in the lines of the system.

Durch die Erfindung wird die sonst erforderliche Entsorgung von wassergefährdendem und umweltbelastendem Schaum-Wasser-Gemisch vermieden. Bisher fielen bei jedem Test 1.000 - 2.000 Liter Schaum-Wasser-Gemisch an. Das bisherige Verfahren ist besonders hinsichtlich des Auffangens von Schaum-Wasser-Gemisch mit einem Durchfluß von mindestens 500 l/min äußerst umständlich und risikoreich.
In der Vergangenheit konnten durch sehr starke Schaumbildung Umweltschäden dadurch entstehen, daß Schaum unkontrolliert überläuft. Diese Gefahr entfällt durch die Verwendung der vorliegenden Vorrichtung.By the invention, the otherwise necessary disposal of water polluting and polluting foam-water mixture is avoided. So far, each test produced 1,000 to 2,000 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.
In the past, could be caused by very strong foaming environmental damage by the fact that foam overflows uncontrollably. This risk is eliminated by the use of the present device.

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.

Im Folgenden wird die Erfindung an einem Ausführungsbeispiel und einer Figur näher erläutert. Die Figur zeigt die erfindungsgemäße Vorrichtung mit einem Durchflußmeßgerät.In the following the invention will be explained in more detail with reference to an embodiment and a figure. The figure shows the device according to the invention with a flowmeter.

Die Figur 1 zeigt den Zumischer 1 in der Löschleitung 3, in die Wasser 4 zu dem Zumischer 1 fließt. Die Leitung 16 führt zum Membrantank 12, von dem eine weitere Leitung 14 zum Zumischer 1 führt. Das Wasser 4, welches über die Leitung 16 zum Membranktank 12 gelangt, wird durch die Membrane 6 aufgehalten, die das Wasser 4 vom Schaumkonzentrat 5 trennt. Bei Betrieb der Zumischeinrichtung kann das Wasser-Schaumkonzentrat über die Leitung 14 dem Zumischer 1 zugeführt werden. Zwischen der Löschleitung 3 und dem Zumischer 1 ist die Bypassleitung 2 mit dem Schaum-Äquivalentventil 8 und dem Durchflussmessgerät 9 angeordnet, wobei an zwei Absperrarmaturen, die 3/2-Wege-Absperrarmaturen darstellen, die die Bypassleitung 2 vor und nach dem Membrantank 12 mit den Leitungen 16, 14 zur Löschleitung 3 und Zumischer 1 verbindet.The FIG. 1 shows the admixer 1 in the discharge line 3, in which water 4 flows to the admixer 1. The line 16 leads to the membrane tank 12, from which a further line 14 leads to the admixer 1. The water 4, which via the line 16 to the membrane tank 12th passes is stopped by the membrane 6, which separates the water 4 from the foam concentrate 5. During operation of the admixing device, the water-foam concentrate can be supplied to the admixer 1 via the line 14. Between the quenching line 3 and the admixer 1, the bypass line 2 is arranged with the foam equivalent valve 8 and the flow meter 9, wherein at two shut-off valves, which represent 3/2-way shut-off valves, the bypass line 2 before and after the membrane tank 12 with the lines 16, 14 connects to the extinguishing line 3 and the mixer 1.
