Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, every other embodiment that those of ordinary skill in the art are obtained all belongs to
In the scope of the utility model protection.
As shown in figure 1, according to a kind of coal-gas recovering conveyance conduit security control implementation described in the utility model, bag
Include coal-gas recovering conveyance conduit, be connected with coal-gas recovering conveyance conduit remove gas chamber and pipe safety control device, the pipe
Road safety control includes PLC control system, explosion venting valve, cut-out glasses valve；The explosion venting valve is positioned close to coal-gas recovering
The inlet side of conveyance conduit, what the cut-out glasses valve was positioned close to coal-gas recovering conveyance conduit goes to gas chamber side；It is described
Cut-out glasses valve carries nitrogen charging device；The explosion venting valve, cut-out glasses valve, nitrogen charging device are connected with PLC control system respectively.
Coal-gas recovering conveyance conduit carries out venting of dust explosion by explosion venting valve, now, the PLC control system detection being connected with explosion venting valve
To after the action of explosion venting valve, control nitrogen charging device discharges nitrogen in the reverse direction to area's gas chamber at once, meanwhile, control cut-out
Glasses valve is closed, and is prevented oxygen from entering and is removed gas chamber, when PLC control system detects that cut-out glasses valve completely closes, control
