Before valve, the valve button for needing to open is pressed, opens selector valve, it is in system fire extinguishing, a plurality of dry powder channel, powder nozzle is same
When stereo-spray dry powder put out a fire.
Whole working principle:
When fire occurs for workover rig, generally there are several possibility.Air-fuel mixture type fire, its main feature is that it is quick-fried to sink to ground under gas
Combustion, oil spray the burning of well mouth of oil well number meter, form large area solid fire；Gas explosion type fire sinks its main feature is that gas leaks
It spreads at low lying ground, meets hot combustion, developing fire is swift and violent；Oil spout type fire, its main feature is that in well head fire occurs for crude oil,
And upward splash, fuel oil drop point randomness are big.
According to fire characteristics, live fighting nozzle needs three-dimensional distribution, in slightly higher 2 levels of location arrangements of well mouth of oil well
Nozzle, horizontal angle control between 45 °~125 °, and jet angle is controlled at 5 °~15 °, carry out dry powder injection to fire well head and go out
Fire puts out well head fire source fire；In about 5~10 meters of well head 2 downward nozzles of height placement, horizontal angle control 45 °~
Between 125 °, jet angle controls -30 °~75 °, carries out diffusing fiery fire extinguishing to square meter ranges about up to a hundred around well head；In oil pipe bridge
4~6 horizontal nozzles of lower setting, adjustable angle, horizontal angle control between 0 °~90 °, jet angle control ± 5 °~±
30 °, optionally it is carried out to diffuse fiery flame failure protection；2 removable angle adjustables are laid near the inflammable place in well site
Mobile nozzle or powder fire monitor, setting knock out the fire in unpredictable region convenient for manual operation on mobile bracket.
This system further includes sequentially connected spare starting gas cylinder, spare driving gas cylinders group and spare dry powder storage facility,
Spare starting gas cylinder is connected to the rear end of the first pressure reducer by emergency button air valve, and spare dry powder storage facility and relief valve connect
