Novel high-efficient spark arrester

Technical Field

The utility model relates to a spark arrester technical field especially relates to a novel high-efficient spark arrester.

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. Flame arresters are also commonly used on pipes that carry flammable gases. If flammable gases are ignited, the gas flame will propagate throughout the piping network. To prevent this risk, flame arrestors are also used. Flame arrestors may also be used on pipelines with open fire equipment to prevent backfire accidents. However, the flame arrester cannot prevent open-flame combustion of combustible gas and liquid in open combustion, and mainly comprises a shell and a filter element, wherein the shell has enough strength to bear impact pressure generated by explosion. The filter element is the primary element that impedes flame propagation. The existing novel high-efficiency flame arrester can basically meet daily use requirements, but has some defects to be improved.

When the existing novel high-efficiency flame arrester is used, the metal mesh filter element is commonly used at present. The metal mesh type filter element has low fire-retardant efficiency and needs to be formed by overlapping multiple layers. Meanwhile, safety is achieved, the domestic flame arrester is usually a 16-22-mesh metal net and is 4-12 layers, the size is large, the use cost is high, and the novel high-efficiency flame arrester is inconvenient to use, so that the problem is solved.
