Technical Field
The utility model relates to a chemical safety device, in particular to a low-pressure-drop pipeline flame arrester.
Background
The gas flame arrestor is designed and manufactured using the principle that when a flame passes through a narrow aperture of a heat conductor, it is extinguished due to heat loss. The fire barrier structure of the fire barrier is of gravel type, wire mesh type or corrugated type. The device is suitable for combustible gas pipelines, such as storage and filling of gasoline, kerosene, light diesel oil, benzene, toluene, crude oil and other oil products or torch systems, gas purification and gasification systems, gas analysis systems, coal mine gas discharge systems, pipe networks of heating furnace fuel gas, and pipeline supplies of acetylene, oxygen, nitrogen and natural gas. The principle of the flame arrester requires that the flame arresting effect is better, the smaller the pores of the flame arresting core, which can result in too much resistance to the gas conveyed in the pipeline and affect the conveying efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the prior art and provide a low-pressure-drop pipeline flame arrester which can ensure the rapid transportation of gas in a pipeline on the premise of ensuring the flame arresting effect.
In order to solve the prior art problems, the utility model discloses a low-pressure-drop pipeline flame arrester, which comprises a shell, wherein a flame-retardant inner core is arranged in the shell, the flame-retardant inner core comprises a flame-retardant coarse core, a flame-retardant steel sleeve and a flame-retardant fine core, the flame-retardant coarse core and the flame-retardant fine core are respectively connected to two ends of the flame-retardant steel sleeve, the flame-retardant coarse core is positioned on one side in the gas entering direction, and the flame-retardant fine core is positioned on one side in the gas leaving direction; the hole of the fire-retardant coarse core is larger than the hole of the fire-retardant fine core, and a plurality of through holes are formed in the fire-retardant steel sleeve.
Preferably, the fire-retardant coarse core, the fire-retardant steel sleeve and the fire-retardant fine core are connected through threads.
Preferably, a plurality of through holes are densely arranged in the fire-retardant steel sleeve.
Preferably, the diameter of the through hole in the fire-retardant steel sleeve is larger than the pore size of the fire-retardant fine core.
The utility model has the beneficial effects that: change single back-fire relief core into tertiary structure, be back-fire relief thick core, back-fire relief steel bushing and back-fire relief thin core respectively, the hole of back-fire relief thick core is bigger some, and the gas of convenient transportation gets into fast, when meetting the condition of a fire, also can get into fast, avoids flame to pile up the explosion. The thick core of back-fire relief plays one-level back-fire relief function, and the hole is the biggest, and flame gets into by the thick partition, and in reentrant the through-hole of back-fire relief steel bushing, further by the partition, the heat is conducted gradually, and the temperature constantly reduces, enters into the thin core of back-fire relief at last, and the hole of the thin core of back-fire relief is minimum, can play final back-fire relief effect. The fire-retardant thick core, the fire-retardant steel sleeve and the fire-retardant thin core are in threaded connection. Of course, the two ends of the fire retardant steel sleeve can be provided with clamping grooves, and the fire retardant thick core and the fire retardant thin core are arranged in the clamping grooves.
