Description

GERMAN

The invention relates to an explosion-proof respiratory system for containers, apparatus and lines, which are used for the storage, processing and transport of flammable liquids and gases and have an outflow channel for gases covered by a flame arrester.

The invention is based on the problem of flames and explosions striking into such Effectively prevent respiratory organs. It consists in that the outflow channel into a mouthpiece passes, at the free end of which a torch can form when the escaping gases are ignited, whereby within the space between the flame arrester and the mouthpiece a chamber with an ejection opening for an explosive gas mixture that is created when it flows out is provided through which the burned gases of the additional mixture for the purpose of extinguishing the combustion exit at high speed as soon as the mixture enters the mouthpiece upon entering the torch has been ignited by the latter.

It is useful if the chamber used to hold the explosive mixture is connected to the Inside the respiratory system above the flame arrester through an ignition channel and an exhaust channel is in connection, the ignition channel preferably being closer to the mouthpiece than the discharge channel.

It is also advantageous that the discharge channel of the chamber serving to receive the explosive gases is designed so that the burnt gases emitted from this chamber reach the surface of the Paint the flame arrester.

A preferred embodiment of the training is that the chamber for the additional The mouthpiece surrounding the gas mixture is designed in the form of a cap, which is attached to the flame arrester equipped filler housing, which may be of a known type, is attached.

Some exemplary embodiments of the invention are shown in the drawing.

Thereafter, a cap c , which has a mouthpiece d , is placed in an outflow channel a, which encloses a flame arrester b. In the space between the flame arrester b and the mouthpiece d a chamber e is provided which is connected to the space itself through an ignition channel directed towards the mouthpiece d and through an outflow duct g- opening above the flame arrester b.

Gases that arise in the container, apparatus or line to be protected and want to escape under a certain overpressure, flow through channel a, the flame arrester b explosion-proof respiratory system

and the mouthpiece d into the open. If they are ignited here by any circumstance, they form a torch, as shown in Fig. I. If its exit velocity drops so far that the torch is able to enter the space between the flame arrester b and the mouthpiece d , the explosive gas mixture produced during the discharge is ignited through the ignition channel f and caused to explode itself (Fig. III). The burnt gases then pass at high speed, in particular through the outflow channel g, and in the exemplary embodiments are expelled over the flame arrester b through the mouthpiece d (Fig. IV). Since they are no longer combustible themselves and are also at high speed, they effectively extinguish the combustion both above the flame arrester b and at the mouthpiece d.

Claims (4)

Claims. 1. Explosion-proof respiratory system for containers, apparatus and lines for storage, processing and transport of flammable liquids and gases with an outflow channel for gases covered by a flame arrester, characterized in that the outflow channel (α ) merges into a mouthpiece (d) at which a flare can form at the free end when the escaping gases are ignited, whereby within the space between the flame arrester (Jb) and the mouthpiece (d) to accommodate an explosive gas- 709-807/164 mixture a chamber (e) is provided with an outlet opening through which the burnt gases of the additional mixture exit at high speed for the purpose of extinguishing the combustion, as soon as the mixture has been ignited by the latter when the torch enters the mouthpiece (d). 2. Device according to claim 1, characterized in that the chamber (e) serving to receive the explosive mixture with the interior of the respiratory system above the flame arrester (b) through an ignition channel (/) and as an exhaust opening through an exhaust channel (§ ·) is in connection, the ignition channel (/) preferably being closer to the mouthpiece (d) than the discharge channel (g ·). 3. Apparatus according to claim 2, characterized in that the ejection channel (g) of the chamber (e) serving to receive the explosive gases is designed so that the burnt gases ejecting from this chamber (e) the surface of the flame arrester (b) coat. 4. Apparatus according to claim 1, 2 or 3, characterized in that the chamber (<?) For the additional gas mixture enclosing mouthpiece (d) is designed in the form of a cap (c) which is attached to the flame arrester (Jb) equipped filler housing is attached. 1 sheet of drawings
