Description
Art
The present invention relates to a kind of safety device, especially a kind of gas emptying pipeline safety device.
Background technology
Safety in production is national stability, the important guarantee of economic development, and the First Principles of countries in the world industry development.
Since reform and opening-up, China's economic development achieves remarkable achievement.However, while economic rapid growth, also companion
Significant proportion is accounted for the generation and coal mining accident of all kinds of security incidents.Gas is a kind of potential clear energy sources, but in coal
Gas is the pernicious gas in mine in ore deposit exploitation, there are blast, outburst danger, safety of coal mines is constituted a serious threat, be colliery
One of major hidden danger.In order to prevent and treat gas ' generally use underground drainage method progress pre-mining drainage gas.China has more than 60%
Mine be to contain methane 25%（Gas explosion limits is 5% ~ 16%）Following low concentration gas, empty pipeline for gas and bring
Potential safety hazard.Simultaneously as gas emptying pipeline is metal material, this is easier to be struck by lightning W, and lightning is induced one underground.When
Lightning hits evacuation port, and low concentration gas will produce burning, or even blast, if being not added with safety devices, blast will be along pipe
Road is propagated, demolition pipeline, extraction equipment, or even travels to underground.
The content of the invention
In order to ensure gas transport pipeline safety, the invention provides a kind of gas to empty pipeline safety device, certain
Blast, flame propagation are prevented in degree, ensure that pipe safety.
The technical solution adopted for the present invention to solve the technical problems is.
Gas emptying pipeline safety device is made up of spark arrester, water-sealing fire-retardant explosion venting device, active explosion suppression device.
The spark arrester（Also known as flame damper, fire division apparatus）It is for preventing inflammable gas and flammable liquid, the flame of steam
The safety device of sprawling, it is made up of housing, fire-retardant core, flange.Having in spark arrester can be by the back-fire relief of the unlike material of gas
Layer, such as wire netting, corrugated plating, porous plate or other charges.After flame enters people's spark arrester, many is divided into by back-fire relief member f parts
Tiny flame flow, due to heat transfer effect（Gas is cooled）It is prevented from flame flow with wall effect.
The water-sealing fire-retardant explosion venting device is by leakage part, water level controller, glass tube water level gauge, metal shunt net group
Into.
The active explosion suppression device is made up of sensor, controller, fire-suppression bottle and nozzle etc..In working method, it is datonation-inhibition can
It is divided into passive type and active, by sensor arrangement near potential quick-fried source, when gas occurring lighting, sensor detects combustion
Burning and explosive flame（Or pressure）, flame or pressure signal are transformed into electric signal and are sent to controller, controller sends instruction,
Start the quick trigger mechanism in explosion suppressor, open explosion suppressor mouth from mechanism is sprayed and spray Explosion suppressant, it is quick to form high concentration suppression
Detonator cloud and mist, fully contacted with flame front, absorb flame energy, terminate pyric chain, make fray-out of flame, exist so as to terminate flame front
Continue to propagate in gas.Active explosion suppression device is logical to use ABC, BC powder extinguishing agent as Explosion suppressant.
The invention has the advantages that gas emptying pipeline safety device is positioned on tube wall using compact sensor, it is several
The normal extraction of gas is not influenceed.Action is quick, high sensitivity., blast, flame propagation are prevented to a certain extent, are ensured
Pipe safety.

Embodiment
In Fig. 1, the spark arrester（Also known as flame damper, fire division apparatus）It is for preventing inflammable gas and flammable liquid, steaming
The safety device of the propagation of flame of gas, it is made up of housing 1, fire-retardant core 2, flange 3.Having in spark arrester can be by the difference of gas
The flame retardant bed of material, such as wire netting, corrugated plating, porous plate or other charges.After flame enters people's spark arrester, by back-fire relief member f
Part is divided into many tiny flame flows, due to heat transfer effect（Gas is cooled）It is prevented from flame flow with wall effect.
In fig. 2, the water-sealing fire-retardant explosion venting device is by leakage part 6, water level controller 8, glass tube water level gauge 9, gold
Category shunting net 10 forms.Under normal delivery situation, methane gas inlet end 4 flows to outlet side 5 by the envelope that blocks water.When outlet end pipe
Road gas explodes, and shock wave caused by blast makes the explosion of venting of dust explosion part 6, release blast pressure；Simultaneously because flame produces
Backflow, by sealing water 7, extinguished by water, so as to reach the purpose of flame arrest, back-fire relief, prevent gas explosion or burning from passing to air inlet
End pipe road, reach the purpose of protection inlet end conveyance conduit and auxiliary device.Metal shunt net 10 on the water surface, effect are to make gas
Body is uniformly emerged from shunting net, does not form big air gap.So when situation of the water under aeration status in water seal arrangement, by distinguished and admirable
The spray evoked is evenly distributed, and is substantially not visible air gap, and the water seal arrangement water surface can cover air inlet completely, reach preferably every
Quick-fried effect.
In figure 3, the active explosion suppression device is made up of sensor, controller, fire-suppression bottle and nozzle etc..Once in container
Combustion explosion, which occurs, for fuel gas can find detonator signal in blast sensor at initial stage and open inhibitor system rapidly to appearance
In device sprinkling inhibitor order simultaneously explosion isolation device action positioned at gas feed and outlet port by container internal combustion make a fire source with
The generation of control blast is simultaneously put out flame in all connected pipeline isolation.
