According to the present invention, the aluminum silicate cotton wave-absorption vibration-reduction noisedamping material and the silk screen structure with functions of flame inhibition and fire resistance are organically combined so as to significantly reduce a flame propagation speed and improve an explosion suppression and flame inhibition performance of the silk screen fire-resistance explosion-suppression apparatus.
Description
Technical field
The present invention relates to the chemical machinery technical field, particularly a kind of suction ripple vibration damping silk screen back-fire relief explosion suppression device.
Background technology
The accident that flammable gas explosion causes in the pipeline brings great threat often for normal production and personal safety.Therefore, prevent and suppress gas burst is the focus of studying in the world wide always.Because all flammable gas explosion disasters are all relevant with the blast pressure ripple with flame, therefore suppress flame propagation and weaken pressure wave intensity, be the problem that the worker of preventing and reducing natural disasters is concerned about most.
Suppress at present the topmost way of flame propagation spark arrester is installed in pipeline exactly.Spark arrester back-fire relief element generally is the narrow slit structure that screen net structure or metallic plate form, the spark arrester of screen net structure is that the multiple layer metal silk screen is positioned in the pipeline perpendicular to gas flow, because its volume is little, lightweight, the extinguishing performance is good, become back-fire relief structure commonly used.The spark arrester of metal plate type structure is that a plurality of metallic plates are parallel to gas flow and are installed in the pipeline junction.When flame passed through silk screen or parallel-plate back-fire relief element, if the spacing of silk screen aperture or parallel-plate is enough little, flame will automatic distinguishing after propagating therein a segment distance.
Yet no matter be silk screen spark arrester or metallic plate spark arrester, the effect of its back-fire relief flame propagation is comparatively remarkable, but also not obvious to the assimilation effect of pressure wave.Therefore, seeking effect and inhale preferably the realization of ripple damping material to effective absorption of pressure wave, is to improve the new way that spark arrester suppresses the combustible medium explosion property.
Summary of the invention
The objective of the invention is: for solving above-mentioned technical problem of the prior art, the suction ripple vibration damping silk screen back-fire relief explosion suppression device of flammable gas explosion in a kind of novel inhibition pipeline is provided, and it realizes fire-retardant datonation-inhibition by inhaling ripple vibration-damping and silencing material and the acting in conjunction of silk screen back-fire relief element.
For achieving the above object, the technical solution used in the present invention is: a kind of suction ripple vibration damping silk screen back-fire relief explosion suppression device is provided, has comprised: silk screen spark arrester, aluminium silicate wool are inhaled ripple vibration-damping and silencing material 3; Described silk screen spark arrester further comprises: pipe flange, spark arrester housing 2, silk screen flame retardant bed 4; Spark arrester procapsid 5 is integral structure with pipe flange I 1, and spark arrester back casing 6 is integral structure with pipe flange II 7; Described silk screen flame retardant bed 4 laterally places in the spark arrester housing 2, and is gripped by spark arrester procapsid 5 and spark arrester back casing 6; Described aluminium silicate wool is inhaled ripple vibration-damping and silencing material 3 and is lining in spark arrester housing 2 inwalls.Explosive flame is after entering the silk screen spark arrester, and lining is inhaled ripple vibration-damping and silencing material 3 at the aluminium silicate wool of spark arrester housing 2 inwalls can absorb the blast pressure ripple, and silk screen flame retardant bed 4 can extinguishing flame simultaneously.
Wherein, it be porous, high-elastic cotton matter that described aluminium silicate wool is inhaled ripple vibration-damping and silencing material 3, and its microstructure is by having certain elasticity and compressible fibrous, and fiber is crisscross, forms the three-dimensional framework structure, the inner formation of skeleton pore.
Beneficial effect: the screen net structure combination that the present invention adopts aluminium silicate wool to inhale the ripple vibration-damping and silencing material and have flame arrest back-fire relief function, realized the vibration damping noise reduction of suction ripple and flame arrest back-fire relief several functions.Simultaneously, owing to placing the aluminium silicate wool of silk screen leading portion to inhale effectively absorption pressure Reeb of ripple vibration-damping and silencing material, significantly reducing flame propagation velocity, therefore, the deflagration flame that enters silk screen flame arrest back-fire relief structure is easier to be suppressed, has significantly improved the datonation-inhibition flame arrest performance of silk screen back-fire relief explosion suppression device.
