Technical Field

The invention relates to the technical field of fire safety equipment, in particular to a flame arrester with a fluctuating flame-retardant core.

Background

There may be the possibility of burning explosion when some combustible gas carries, consequently generally all can install a flame arrester in the pipeline and play safety guarantee's effect, it has the back-fire relief core, flame arrester shell and annex to constitute, thereby can be given the dispersion by the tiny mesh in the filter core when the flame of burning passes through the back-fire relief core and reduce flame size, thereby make through the gas that just does not burn after the back-fire relief core and reach safety standard, but the structural feature and the in-service use of flame arrester itself still can the problem:

1. when the flame arrester is used, the flame arrester is arranged between gas conveying pipelines, and accordingly, when gas burns or explodes, the gas enters from one side of the flame arrester and passes through the flame arresting core to be extinguished, wherein the flame arresting core is fixed after being installed, so that the temperature of the whole flame arresting core is very high when the time for treating the combustion gas is too long, and the other end of the flame arresting core cannot achieve the effect of flame arresting due to the fact that the temperature is too high to generate tempering, and the flame arresting core cannot be burned to continue to arrest the flame even if the temperature is too high;

2. the inner structure of back-fire relief core is simple, only install one deck back-fire relief core, the outside adopts two shells to cup joint firmly, just so need adopt sealed processing in back-fire relief core department, and need seal whole gas transmission pipeline and then dismantle when back-fire relief core goes wrong or burns out, install again after the dismantlement, consuming time and power, the change of back-fire relief core is not only because damaging simultaneously, particulate matter in the combustion gas is adsorbed too much by the filter core and also can cause the back-fire relief effect to worsen, this also is one of the reasons that back-fire relief core needs frequent change.
