Description
Technical field
This utility model relates to a kind of composite pipeline detonation seal, belongs to fire-retardant datonation-inhibition technical field.
Background technology
As flammable explosion hazard gases and fluid-carrying lines and production, the important safety parts of storage device, current back-fire relief
Device mainly has metal mesh type, ripple type, packing type, porous template etc. several, and its principle is by heattransfer effect and wall effect
Pipeline flame is stoped to be propagated.Transport pipeline is divided into some by spark arrester, and flame is when pipe transmmision, when caliber reduces,
Due to conduction of heat and wall effect, heat loss is just gradually increased, ignition temperature and the most corresponding reduction of flame propagation velocity.Work as caliber
Little to certain ultimate value time, the heat loss of tube wall is more than reaction heat, so that fray-out of flame.But when common flame combustion transfers to
When detonation or even detonation, in pipeline, temperature and pressure rises rapidly, and spark arrester can not prevent the propagation of detonation wave, it is easy to
Damage under the effect of detonation wave, it is impossible to prevent pipeline from destroying further.
Common explosion suppression device includes passive type explosion suppression device and active explosion suppression device.Passive type explosion suppression device is by surpassing
The front pressure wave propagated in explosive flame, smashes or makes container to throw in the container containing Explosion suppressant, makes Explosion suppressant dispersion be formed
High concentration rock dust cloud or water smoke band, be just suppressed when the explosive flame lagging behind pressure wave and quick-fried wind arrives and put out.Actively
Formula explosion suppression device is light, heat or the pressure that spark-test sensor detects that blast produces, and sends a signal to Explosion suppressant and sprays dress
Putting, Explosion suppressant flusher the most quickly sprays Explosion suppressant, reaches effectiveness of explosion suppression.And these explosion suppression devices influence factor is more,
It is susceptible to situation about responding not in time.
Utility model content
This utility model to solve technical problem is that: for the disadvantages mentioned above of prior art, it is provided that a kind of simple in construction, resistance
The composite pipeline detonation seal that quick-fried back-fire relief is effective.
In order to solve above technical problem, the technical solution of the utility model is as follows:
A kind of composite pipeline detonation seal, including fire retardant device, fire retardant device is mainly by cylinder blanket be arranged on circle
Fire-resistant core body composition in cylindrical outer cover, one end of cylinder blanket is provided with first interface, and first interface is provided with the first bend pipe,
The other end of cylinder blanket is provided with the second interface, and the second interface is provided with the second bend pipe.
Specifically, this pipeline detonation seal can make the flame in pipeline decay rapidly with detonation wave intensity, until disappearing,
Thus reach fire-retardant datonation-inhibition effect.And when pipeline detonation seal is affected by detonation wave and to be damaged, fire retardant device can and
Time intercept flame propagate in the duct.
The most perfect technical scheme of this utility model is as follows:
Preferably, fire-resistant core body is cellular.
It is further preferred that the material of fire-resistant core body is pottery.
Preferably, fire-resistant core body includes one group of metallic plate along the axially in parallel arrangement of cylinder blanket.
Preferably, the first bend pipe is provided with entrance, and the porch of the first bend pipe is provided with the first joint；Second bend pipe is provided with out
Mouthful, the exit of the second bend pipe is provided with the second joint.
It is further preferred that first, second bend pipe is continuous bend deformation, its angle of bend is 180 degree.
The utility model has the advantages that, use continuous bend 180 degree bend pipe as conveyance conduit due to detonation wave turning
Effect, the flame entered in bend pipe can be decayed the most continuously with detonation wave, until disappearing, thus reaching effectiveness of explosion suppression, preventing brokenly
Bad fire retardant device.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is further described.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the structural representation of fire retardant device in this utility model.
Detailed description of the invention
Embodiment one
The composite pipeline detonation seal of the present embodiment, its structure as shown in Figure 1, Figure 2 and Figure 3, including fire retardant device 3, hinders
Fire device 3 is mainly made up of cylinder blanket 31 and the fire-resistant core body 32 being arranged in cylinder blanket 31, cylinder blanket 31
One end be provided with first interface, first interface is provided with the first bend pipe 1 stretching out shell 31, and the first bend pipe 1 is provided with entrance, first
The porch of bend pipe 1 is provided with the first joint 4, and such first bend pipe 1 is connected with conveyance conduit by the first joint 4；Outside cylinder
The other end of shell 31 is provided with the second interface, and the second interface is provided with the second bend pipe 2 stretching out shell 31, and the second bend pipe 2 is provided with out
Mouthful, the exit of the second bend pipe 2 is provided with the second joint 5, and such second bend pipe 2 is connected with conveyance conduit by the second joint 5.The
One bend pipe the 1, second bend pipe 2 deforms in continuous bend, and its angle of bend is 180 degree, due to the corner-turning effect of continuous bend pipeline,
Enter the flame in first bend pipe the 1, second bend pipe 2 and detonation wave intensity can decay the most continuously, reach effectiveness of explosion suppression, and prevent
Detonation wave destroys fire retardant device.
It addition, fire-resistant core body 32 includes one group of metallic plate along the axially in parallel arrangement of cylinder blanket 31.This group metal
Plate is parallel arrangement in cylinder blanket 31, forms the passage allowing pipeline pumped (conveying) medium to pass through, passage between adjacent metal sheets
Narrow, when the conveyance conduit generation condition of a fire, due to critical tube effect, the flame entering slype can be decayed rapidly, until disappearing
Lose, cause flame to be blocked in fire-resistant core body 32, thus prevent flame from propagating in conveyance conduit.
Embodiment two
The present embodiment is with the difference of embodiment one: fire-resistant core body 32 is in cellular, and fire-resistant core body 32
Material is pottery.Having, in cellular fire-resistant core body, the honeycomb hole that multiple aperture is small, honeycomb hole can conveyance conduit medium.But
Being when accidents such as the conveyance conduit generation condition of a fire, due to critical tube effect, the flame intensity entering honeycomb hole can decay rapidly, directly
To disappearing, flame is blocked in fire-resistant core body 32, causes flame propagation in conveyance conduit to be interrupted.
In addition to the implementation, this utility model can also have other embodiments.All employing equivalents or equivalence become
Change the technical scheme of formation, all fall within the protection domain of this utility model requirement.
