Description
Technical field
The utility model relates to coalmine ventilation and security fields, is specially the datonation-inhibition fire retardant device of a kind of gas drainage pipeline.
Background technology
Because the fire damp conveyance conduit is in connected mode in parallel and series connection, in case after the local appearance leakage of fire damp conveyance conduit and burning things which may cause a fire disaster enter pipeline, burning and detonation occur, can propagate along pipeline, feed through to other zone, be unfavorable for the safety of whole gas pumping induction system.
Summary of the invention
There is the problem of larger potential safety hazard in the utility model in order to solve existing gas drainage pipeline, provide a kind of gas drainage pipeline datonation-inhibition fire retardant device.
The utility model is to adopt following technical scheme to realize: the datonation-inhibition fire retardant device of gas drainage pipeline, comprise datonation-inhibition system and back-fire relief system, datonation-inhibition system comprises controller and is arranged on the extraction pipeline and the flame detector that communicates with it and fire extinguisher, the output of flame detector is connected with the input of controller, and the output of controller is connected with the input of fire extinguisher; The back-fire relief system comprises housing, is positioned at the wire lath of housing, the top of housing is provided with the venting of dust explosion plate, and the left and right sides sidewall of housing is provided with gas inlet pipe and gas escape pipe, the bottom of housing is provided with the sealing water that floods gas inlet pipe bottom, and is provided with on the housing in the sealing water outside and the level sensor and the water-level gauge that seal water and be communicated with.
When flame detector detected the extraction entrance and burning things which may cause a fire disaster occurs, controller can receive coherent signal and send instruction to fire extinguisher, sprayed at a high speed extinguishing chemical, thereby the purpose that the flame of realizing occurring puts out guarantees the safety of extraction pipeline; Simultaneously when blast or burn in gas escape pipe end; the shock wave that blast produces makes the explosion of venting of dust explosion plate, discharges blast pressure; sealing water plays flame arrest, back-fire relief effect, stops gas explosion or burning to pass to gas inlet pipe, reaches the purpose of protection gas inlet pipe and ancillary service thereof.Overcome the problem that there is larger potential safety hazard in existing gas drainage pipeline.
Housing is left shell and the right shell body that is interconnected, level sensor is communicated with left shell and right shell body, water-level gauge is positioned at the left shell outside, gas inlet pipe is positioned at the left shell sidewall, the gas escape pipe is positioned at the right shell body sidewall, the venting of dust explosion plate is positioned at the right shell body top, has further promoted the performance of flame arrest, back-fire relief.
The utility model reasonable in design is reliable, realized the establishment to the gas explosion of extraction pipeline, process of inhibition has at a high speed, efficiently characteristics, and the generation of stopping extraction pipe network chain explosion phenomenon, Fire resistances is higher, has advantage simple in structure, easy to operate and that cost is low.
