Abstract
The invention relates to the technical field of chemical machinery and discloses a deflagration overpressure relief device with wave adsorption and flame suppression functions. The deflagration overpressure relief device is formed by pipe flanges, a rupture disk assembly, a relief pipeline, an aluminum silicate wool porous material and a fireproof corrugated plate; the rupture disk assembly is arranged at the joint of the pipe flanges; the aluminum silicate wool porous material is attached to the inner wall of the relief pipeline; and the fireproof corrugated plate is arranged at the tail end of the relief pipeline. In the emergency discharging process, a rupture disk is opened under a rated opening pressure; a discharged deflagration medium is subjected to effective wave adsorption, pressure reduction and noise reduction by the aluminum silicate wool porous material arranged on the inner wall of the pipeline so as to obviously inhibit the pressure, the flame speed and the voice strength; and then the discharged deflagration medium is subjected to fire retardance and flame suppression by the fireproof corrugated plate at the tail end. After the discharged material passes through the device, the flame and the pressure are inhibited in a combined manner and the safety of containers, equipment and people close to an outlet of the relief pipeline is effectively protected.
Description
Technical field
Patent of the present invention belongs to the chemical machinery technical field, relates to a kind of detonation pressure relief device of inhaling ripple flame arrest function that has.
Background technique
All flammable than multimedium in pressure vessels for the chemical industry and the equipment.In case the generation blast accident, the pressure wave of generation will cause damage to container and equipment.Release is to slacken the effective measures that fire intensity in the container.Traditional mode of releasing is to adopt bleeder with combustible medium, products of combustion, flame and the pressure wave surrounding space of releasing, or cause other zones by the venting of dust explosion conduit, but involving flame, the pressure of releasing out still personnel, equipment and surrounding environment are brought potential threat.How on the basis that guarantees drainage function, slacken the pressure wave intensity of releasing out, and knock down the flame, be problem needing to overcome.
Summary of the invention
Involve flame still brings potential threat to personnel, equipment and surrounding environment problem for solving the pressure that traditional pressure release mode releases out.
Technological scheme of the present invention: a kind of detonation pressure relief device with suction ripple flame arrest function, consisted of by pipe flange, rupture disk assembly, discharge conduit, aluminium silicate wool porous material, back-fire relief corrugated sheet, the rupture disk assembly is installed in the pipe flange joint, the aluminium silicate wool porous material is attached to the pipeline inner wall of releasing, at the terminal back-fire relief corrugated sheet of installing of the pipeline of releasing.Safety relief device-rupture disk, suction ripple vibration damping silencer-aluminium silicate wool porous material, back-fire relief flame trap-back-fire relief corrugated sheet are combined into complete device, the function that has realized safety relief, inhaled the multinomial safety installationss such as the noise reduction of ripple vibration damping, back-fire relief flame arrest.
Beneficial effect: the material of releasing is through behind this device, and the high-strength press Reeb is absorbed by the aluminium silicate wool porous material, and the sound that explodes is weakened, and flame is by the extinguishing of back-fire relief corrugated sheet, container, equipment and the personal security of effectively having protected the bleeder pipe way outlet to close on.
Description of drawings
Fig. 1 is structural representation of the present invention.
Wherein: 1-pipe flange, 2-rupture disk assembly, 3-release pipeline, 4-aluminium silicate wool porous material, 5-back-fire relief corrugated sheet.
Embodiment
Below in conjunction with accompanying drawing the present invention is elaborated.
Embodiment 1: a kind of detonation pressure relief device with suction ripple flame arrest function, consisted of by pipe flange 1, rupture disk assembly 2, discharge conduit 3, aluminium silicate wool porous material 4, back-fire relief corrugated sheet 5, rupture disk assembly 2 is installed in pipe flange 1 joint, aluminium silicate wool porous material 4 is attached to pipeline 3 inwalls of releasing, at the pipeline 3 terminal back-fire relief corrugated sheets 5 of installing of releasing.
With reference to Fig. 1, in the present embodiment, when firing in by shielding container, if container inner pressure reaches the bursting pressure of rupture disk assembly 2, rupture disk assembly 2 is opened, and has fired product, does not fire medium, flame and pressure wave all release to the pipeline 3 of releasing.In the pipeline 3 of releasing, pressure wave is absorbed by aluminium silicate wool porous material 4, and blast sound is weakened by aluminium silicate wool porous material 4, and flame is by 5 extinguishing of back-fire relief corrugated sheet.Behind this device, flame and pressure wave united suppress, and have effectively protected container, equipment and personal security.
Above content is the further description of the present invention being done in conjunction with optimal technical scheme, can not assert that the implementation of invention only limits to these explanations.Concerning the general technical staff of the technical field of the invention, under the prerequisite that does not break away from design of the present invention, can also make simple deduction and replacement, all should be considered as protection scope of the present invention.
Claims (1)
