Abstract
The utility model discloses a flame trap in an oil-gas pipeline, belonging to the field of the fire retardant and explosion-proof equipment of the transport pipeline. Aiming at the condition that the inflammable gas and the vapour of the inflammable liquid in the oil gas transport pipeline can accidentally lead to the fire hazard, and the flame propagation speed can reach more than 1 km /s instantly, and then the huge impact wave can be generated, the flame trap in an oil-gas pipeline adopts the steel cast outer case having bigger impact strength, and an upper end cover is added with a baffle plate which can prevent the impact of the detonation wave to disperse the bundling flame to force the flame to change the direction, and the fire is automatically extinguished via a plurality of layers of fire retardant discs formed by winding the stainless steel corrugated plates and arranged in the outer case body, and therefore, the purpose of automatically extinguishing the fire is achieved. The flame trap in an oil-gas pipeline has the advantages of high strength of bearing the detonation wave, high assurance coefficient, corrosion resistance, combustion resistance, etc.
Description
The utility model belongs to the fire and explosion resistant device field of conveyance conduit.
Generally mostly be as main conveying device with pipeline at petrochemical enterprise at present, gas that is transmitted in the pipeline or liquid vapors major part all belong to inflammable gas, the possibility that burning and blast take place is very big, seriously the safety of prestige association's storage device and conveyance conduit.According to field investigation and document record, employed fire retardant device in petrochemical system at present, be to adopt the flame retardant bed of 16-40 purpose wire netting as spark arrester at the fifties, this spark arrester has not reached the back-fire relief effect, its control flame propagation velocity can only reach 100 meter per seconds, thereby caused the generation of some accidents, caused bigger loss for the country and people's property.The safe fire retardant device that some developed countries all adopt new material to make in this field, the Lao Shiweige flame damper factory as West Germany produces various spark arresters according to the DIN standard and belongs to product advanced in the world.But still exist effect not very good, the more high shortcoming of cost.
The purpose of this utility model is to have invented at above-mentioned situation a kind ofly can guarantee storage device and conveyance conduit safety, and is simple in structure, the oil and gas pipes detonation seal that effect is very good.
The utility model takes following technical scheme to realize: owing to producing fire in inflammable gas in the pipe-line and the flammable liquid steam meeting accident, flame transmission speed moment can reach the above huge impact ripple that produces of 1,000 meter per seconds, so this pipe-line detonation seal has selected for use the bigger cast steel material of impact strength to do shell.But on upper end cover, be processed with the baffle plate of multilayer antiknock Hong wave impact, be used to disperse boundling flame, force flame to change direction, by being installed in the back-fire relief dish that the several layers stainless steel material is manufactured in the shell body corrugated plating is entwined, fire is extinguished automatically, thereby reach the purpose of auto extinguishing.
This oil-vapor pipe detonation seal not only has can make ducted oil gas body pass through unblockedly, and the unexpected flame that produces in the pipeline can be extinguished effectively automatically; It is strong, corrosion-resistant that the back-fire relief dish of installing in the housing that is entwined by the stainless steel wave card has an extinguishing ability, advantages such as anti-burning; The shell of being made by cast steel material can bear the enormous impact ripple that detonation wave produces, the limit back-fire relief speed V=2300m/s of this detonation seal, safe back-fire relief speed V=1300m/s, pressure falls under maximum stream flow and is not more than 498Pa, the tightness water pressure test of housing can bear 2,4MPa, and the housing ne-leakage is indeformable and damage.
Figure of description is an example structure generalized section of the technical program, 1 upper end cover among the figure, 2 fastening bolts, 3 sealing gaskets, 4 shell bodies, 5 back-fire relief dish clamp nuts, retainer plate on the 6 ring-type back-fire relief dishes, 7 back-fire relief dishes, 8 retaining pads, retainer plate under the 9 ring-type back-fire relief dishes, 10 back-fire relief dish fastening bolts, 11 air inlet ring flanges, 12 gas outlet ring flanges, 13 baffle plates.
Below in conjunction with accompanying drawing this real new structure is further described:
By fastening bolt (2) and sealing gasket (3) upper end cover (1) is installed at the shell body of making by cast steel material (4), but be processed with the baffle plate (13) that multilayer has antiknock Hong wave impact on the upper end cover, the back-fire relief dish (7) that several layers is entwined by the stainless steel wave card is housed in housing, multilayer back-fire relief dish fills up (8) with back-fire relief dish fastening bolt (10) by retainer plate (9) retaining under retainer plate (6) on the ring-type back-fire relief dish and the ring-type back-fire relief dish, back-fire relief dish clamp nut (5) is fixed into one, be installed in the shell body, on housing, also be processed with air inlet ring flange (11) and link to each other with conveyance conduit with gas outlet ring flange (12).
Claims (2)
1, the quick-fried device of a kind of oil and gas pipes back-fire relief includes shell body, upper end cover, sealing gasket, fastening bolt, air inlet ring flange.The gas outlet ring flange is characterized in that the back-fire relief dish that several layers is entwined with the stainless steel wave card being installed making with cast steel material in the shell body, but is processed with the baffle plate of multilayer antiknock Hong wave impact on the upper end cover.
2, the quick-fried device of a kind of oil and gas pipes choke as claimed in claim 1 is characterized in that the several layers back-fire relief dish installed in the enclosure.By retainer plate under retainer plate on the ring-type back-fire relief dish and the ring-type back-fire relief dish, the shelves pad is fixed into one with back-fire relief dish fastening bolt and back-fire relief dish clamp nut.
