Die vorliegende Erfindung betrifft eine Einrichtung zum Feuerlöschen mittelst flüssiger Kohlensäure, wodurch ein Erstarren der letzteren infolge der beim Uebertritt in den gasförmigen Zustand erzeugten Kälte und damit eine Verzögerung in. der weiteren Umsetzung in Gasform vermieden wird. Obgleich diese Einrichtung zur Aufstellung in Schiffsräumen, d. h. also unter vortheilhafter Raumausnutzung construirt worden ist, so kann sie ebenso gut in Lagerräumen, Docks u. s. w. Anwendung finden, auch fahrbar angebracht werden.The present invention relates to a device for extinguishing fire by means of liquid Carbonic acid, causing the latter to solidify as a result of the transition to the gaseous State generated cold and thus a delay in the further implementation in gaseous form is avoided. Although this device for installation in ship rooms, i. H. so has been constructed with advantageous use of space, it can just as well be used in storage rooms, Docks and so on are used, can also be mounted on wheels.

Die Behälter der flüssigen Kohlensäure werden in einem Gestell in Batterieform in beliebiger Anzahl zusammengestellt, lassen sich ohne grofse Mühe auswechseln und entleeren ihren Inhalt in ein gemeinsames Hauptrohr, aus welchem ihn ein Vertheiler in beliebiger Richtung ausstößt. Das ganze Gestell ist von einem doppelwandigen Mantel umgeben, in dessen Zwischenraum ein beliebiges Heizmaterial (Wasserdampf, heifses Wasser) geleitet wird, und welches selbst leicht von dem Gestell entfernt werden kann.The containers of liquid carbonic acid are in a rack in battery form in any The number can be changed without great effort and their contents emptied into a common main pipe, from which a distributor expels it in any direction. The whole frame is from surrounded by a double-walled jacket, in the space between which any heating material (Steam, hot water) is passed, and which itself easily from the frame can be removed.

Das Gestell A, welches zur Aufnahme der Kohlensäurebehälter dient, besteht aus den\ auf Stützen b b ruhenden Boden α und einer Anzahl von Scheidewänden E, welche unter sich und mit dem Boden durch Winkelstücke HH und zwei quer laufende Verbinder / vereinigt sind; letztere stützen die oberen Enden der Scheidewände mittelst sechs abstellbarer Keilverbände, da nach der Zeichnung sechs Abtheilungen im Gestell zu je zwei Kohlensäurebehältern A vorgesehen sind. Die Behälter ruhen in massiven, ihren Fufsstücken entsprechend geformten Stücken B, welche mit dem Boden α in geeigneter Weise verbunden sind (Fig. 2), und werden am oberen Ende mittelst Gelenkklappen D, welche sich mit ihren freien, der Querschnittsform der Behälter entsprechenden und Kreissegmente darstellenden Enden gegen jene legen (Fig. 4), in senkrechter Stellung gehalten. Die Klappen sind durch Scharniere e auf dem Rand der Scheidewände E und den Stücken H befestigt und werden, wenn sie horizontal gegen die eingesetzten Behälter gelegt worden sind, mittelst zweier Stäbe F,, welche durch je sechs auf. ebensoviel'· Klappen vorgesehene Oehre geschoben Werden,, unbeweglich niedergehalten (Fig. i, 3 und 4).The frame A, which is used to hold the carbon dioxide tank, consists of the floor α resting on supports bb and a number of partition walls E, which are united below and with the floor by angle pieces HH and two transverse connectors /; the latter support the upper ends of the partitions by means of six retractable wedge bandages, since according to the drawing six compartments are provided in the frame, each with two carbonic acid containers A. The containers rest in solid, their feet shaped pieces B, which are connected to the bottom α in a suitable manner (Fig. 2), and are at the top by means of hinged flaps D, which with their free, the cross-sectional shape of the container and corresponding Place the ends representing segments of the circle against those (Fig. 4), held in a vertical position. The flaps are fastened by hinges e on the edge of the partitions E and the pieces H and, when they have been placed horizontally against the inserted containers, are opened by means of two rods F, which each have six. just as much as the ears provided for flaps are pushed, held down immovably (Figs. 1, 3 and 4).

Die Rohrleitung über den Behältern (Fig. 4) besteht aus einem Hauptrohr J mit je drei seitlichen Zweigrohren k, deren Stutzen L mit den Ausflufsstutzen M der Kohlensäurebehälter verschraubt werden. Das Rohr J ruht auf zwei Platten N, welche von den Winkelstücken der Aufsenwände E¹ und den Stutzen P getragen werden (Fig. 3) und trägt zur Anzeige des Gasdruckes ein Manometer Q. Sein Hahn R dient zum Entweichenlassen der Kohlensäure in einen Vertheiler und damit an den gefährdeten Ort.The pipeline above the containers (Fig. 4) consists of a main pipe J with three lateral branch pipes k, the nozzle L of which is screwed to the outflow nozzle M of the carbon dioxide container. The pipe J rests on two plates N, which are supported by the elbows of the outer walls E ¹ and the nozzle P (Fig. 3) and carries a manometer Q to indicate the gas pressure. Its tap R is used to let the carbonic acid escape into a distributor and thus to the endangered place.

Durch die plötzliche Veränderung des Aggregatzustandes der austretenden Kohlensäure wird dem flüssigen Theil derselben so viel Wärme entzogen, dafs er erstarrt; indem dieseDue to the sudden change in the physical state of the escaping carbon dioxide so much heat is withdrawn from the liquid part of it that it solidifies; by this

Claims

Transformation both in the containers of the liquid and especially strong in occurs to the distributors, it prevents or delays the further outflow.

For the purpose of avoiding these disadvantages, which result from the rapid evaporation of the To cause liquid carbonic acid, it is necessary both the container and that To heat pipe system. For example, this can be achieved by using the Drawing illustrated facility.

The frame is surrounded by a double casing (Fig. 2) forming two Abtheile, a rear and a front S ¹ S ² by the vertical connectors T ff of the cladding panels lie between the two. Each of these sections, which for itself forms a whole and is attached to the other as described below, is again divided into two spaces 1 and 2 by the same but horizontal pieces V. The four rooms created in this way are each provided with a lockable inlet nozzle X and an outlet nozzle Y for the heating medium to be used. The fastening of the two vertical sections s ¹ s ² is expediently effected by means of latches or hooks and on the base piece α by wedge bolts, which can be easily removed from the latter at any time (handles p) -

Such a four-part division of the hollow jacket surrounding the frame brings the advantage with it, according to need and selection and with consideration of the number of those to be used Carbon dioxide tank one or more of the rooms can be placed on the heater.

At the top the device is closed by a cover Z fastened by means of a wedge lock η ; the holes m in the cover plate allow the screw closure heads of the carbon dioxide containers to pass through.

The idea of the invention should not be exhausted by the construction described here, it can e.g. B. the entire device by immersion in a hot fluid direct heating by means of combustible bodies and so on.

Pat en τ claim:

A device for extinguishing a fire by means of liquid carbon dioxide, in which a battery of carbon dioxide containers located in a frame is used, characterized in that the frame is surrounded by a hollow jacket formed from two vertical parts (S ¹ S ² ) , which is surrounded by a central, horizontal partition are divided into two compartments (1 and 2) so that, depending on requirements, the heating medium (steam, water) can be routed into one, two or more compartments by having an inlet nozzle (X) and a discharge nozzle (Y) for each of them. is provided.
