Background

flame arrestors are safety devices used to prevent the spread of flames of flammable gases and flammable liquid vapors. The device for preventing the passage of a propagating flame (deflagration or detonation), which is generally installed in a conduit for transporting combustible gases, or in a ventilated tank, consists of a flame-retardant core, a flame-retardant casing and accessories. The propagation of the combustion reaction is prevented by the wall effect created between the flame arrestor core and the flame arrestor housing.

One of the requirements for combustion is to reach a certain temperature, i.e. the ignition point. At present, current spark arrester simple structure only can play the back-fire relief effect when inflammable gas or liquid burning, but can not realize the monitoring to the temperature of inflammable gas or liquid, and the back-fire relief situation is from knowing, and in addition, the back-fire relief core is made for the metal mesh, has the gap, in case the high temperature or ageing, hardly prevents the reaction of burning propagation completely, consequently designs a back-fire relief equipment that has high security now.
