Embodiment Construction

[0057] figure 1 An exemplary embodiment of a fire extinguishing device 10 according to the invention is shown, which can be integrated into a gas line 2 via an inlet line flange 22 and an outlet line flange 20 . During operation, gas flows via the inlet line connection 22 into the interior space 4 of the fire extinguishing device 10 and from there into the exterior space 6 . The inner space 4 is designed to open downwards, so that gas flows into the outer space 6 . In this case, the gas leaves the extinguishing device 10 via the outlet line flange 20 . If the progress of the flame front is not hindered by the extinguishing device 10 , the flame front generally moves in the opposite direction, ie enters the extinguishing device 10 through the outlet line flange 20 and leaves the extinguishing device through the inlet line flange 22 .

[0058] A container 12 is arranged above the interior space 4 and the exterior space 6 . The container 12 has a central cylindrical extinguish...

Abstract

The invention relates to a method for extinguishing a flame front in a gas line (2), wherein the method has the following steps: (a) introducing a fire extinguishing agent into a fire extinguishing region (L) of the gas line (2) under overpressure, furthermore, (b) introducing a barrier liquid into a barrier region (S) of the gas line (2) such that the barrier liquid remains in the barrier region(S) such that gas flowing through the gas line (2) must flow through the barrier liquid in the barrier region (S).

Description

technical field [0001] The invention relates to a method for extinguishing a flame front in a gas line and, according to a second aspect, to an extinguishing device for a gas line. Background technique [0002] Gas pipelines are transportation devices for gases, especially combustible gases. This concerns, for example, pipelines in which gases, such as natural gas, are transported over long distances. But this can also involve shorter gas lines, such as transport lines between refineries and gas storage tanks, or from transport vehicles to gas storage tanks. [0003] In such gas lines through which combustible gases flow, there is always the risk of the combustible gases being ignited, for example due to the formation of sparks. Such sparks can occur due to defective electrical devices (such as sensors) or due to electrostatic discharge. A flame front is formed due to the ignition of the gas in the gas line, which spreads in the gas line. This can lead to serious damage ...
