Description

Self-locking spherical sealing gas flame arrester Technical Field The invention relates to the technical field of torpedo ladle baking, in particular to a self-locking spherical sealing gas flame arrester. Background The principle of the gas flame arrestor in the existing torpedo ladle baking assembly is mainly based on the phenomenon that flame is extinguished due to heat loss when passing through a narrow pore or channel. In particular, such flame arresters are generally composed of a plurality of fine, uniform or non-uniform channels or apertures, which are dimensioned to be as small as possible, which are divided into a plurality of fine flame flows after the flame has entered the flame arrestor, and which, due to the large heat transfer areas of these channels or apertures, undergo a heat exchange through the channel walls, resulting in a significant drop in temperature, and when the temperature drops to a certain extent, the combustion conditions of the flame are no longer satisfied, and the flame is extinguished. However, the flame arresters using dense pore channels have the defects that, on one hand, the dense pore structure prevents flame propagation, and meanwhile, the system resistance loss is obviously increased to influence the normal flow and pressure of a pipeline system, and on the other hand, once the flame arresters are tempered, the flame arresters are damaged, and generally need to be replaced integrally or be maintained in a complex manner, so that the maintenance cost is high.
