Gravel flame arrester is a safety device used to prevent hydrogen flame from spreading out. It is composed of a solid material (a fire element) that can be passed through a gas, with a number of tiny channels or gaps. Asked the fire element in the gap or channel as small as possible, so when the flame entered the flame arrester, fire retardant components are divided into many small fire flow, due to the heat transfer function (gas cooled) and the wall effect, the flame flow quenching.
1, the explosion resistance of qualified, continuous 13 times the performance of the flame retardant test, each time can resist fire.
2, resistance to burn the performance of qualified, burn resistant test for 1 hours, during which no tempering.
3, the flame arrester housing bear no less than 0.9MPa of the hydrostatic test, no leakage.
The product has reasonable structure, light weight and corrosion resistance. Easy maintenance, easy installation. Flame arrester core made of stainless steel, corrosion resistance and easy cleaning.
The flame arrester is mainly composed of two parts, the shell and the filter element. The shell should have sufficient strength to withstand the shock pressure generated by the explosion. Filter is to prevent the spread of the main components of the flame, the use of metal mesh filter and corrugated filter two. Metal mesh filter with a diameter of 0.23~0.315mm stainless steel or copper mesh, multilayer overlap. At present, the domestic flame arrester usually adopts 16~22 mesh, which is the 4~12 layer.
Stainless steel, copper nickel alloy, aluminum or aluminum alloy support for corrugated filter element. The violent flame corrugated type arrester can prevent deflagration, and can withstand the mechanical and thermal effects of the corresponding, small flow resistance, easy cleaning and replacement.
