Extinguishing device 80 is arranged on the top and middle and lower part of the colliery silo.Each carbon dioxide extinguisher installation 80 can be sent out in raw coal
When being conigenous combustion from trend to colliery silo in be filled with carbon dioxide, the oxygen needed for completely cut off raw coal combustion is being gone out
Fire.
Specifically, as shown in figure 17, carbon dioxide extinguisher installation 80 includes：Temperature sensor 81, controller 82, fire extinguishing dress
Starter 83 and fire extinguishing sprayer 84 are put, temperature sensor 81 is arranged on the inside of colliery silo for monitoring inside the silo of colliery
Temperature；Controller 82 is connected to receive the temperature in the colliery silo of the monitoring of temperature sensor 81 with temperature sensor 81, when
When the rate of climb of the temperature in the silo of colliery that temperature sensor 81 is monitored is more than preset value, you can determine in the silo of colliery
Raw coal occur spontaneous combustion, subsequently send control instruction from controller 82 to extinguishing device starter 83；Extinguishing device starter 83
It is filled with into the silo of colliery according to the fire extinguishing sprayer 84 that the control instruction that controller 82 sends opens carbon dioxide extinguisher installation 80
Appropriate carbon dioxide is so as to the raw coal of spontaneous combustion be put out.
Carbon dioxide extinguishing agent is fire-fighting efficiency highest inert gas agent.Secondly, carbon dioxide has normal
Maximum specific weight in the inert gas agent seen, combustible gas and oxygen are squeezed under the conditions of equal ambient as inerting (fire extinguishing) gas
The displacement efficiency of gas compares other inert gas agents and has great advantage, is being oxygen barrier asphyxia to spontaneous combustion coal package action
Effect is stronger.According to this feature, decanting point can be respectively provided with the upper, middle and lower portion of colliery silo and spurt carbon dioxide：
On silo top, injecting carbon dioxide gas can quickly form carbon-dioxide protecting layer and cover coal on coal surface
Charcoal；In the silo injecting carbon dioxide gas in bottom can make carbon dioxide gas know from experience gradually disperse upwards using air duct effect in storehouse
To whole dump, the oxygen concentration of dump is reduced.Further, the condensing temperature of carbon dioxide is also significantly less than nitrogen, it is easier to big
Amount storage, efficiency of storage is with the obvious advantage with floor space compared with fire extinguishing nitrogen system.The startup of its fire extinguishing system is using pneumatic
The supply of electric power for being not rely on harbour is spurted in mode, its fire extinguishing, is the effective protection to nitrogen purging system.
Under normal circumstances, coal storage silo volume is 3 ten thousand steres, maximum in the reserves average out in view of coal in silo
In the case of the half (1.5 ten thousand stere) of reserves, the fire protection space of CO2 extinguishment system is about the half of dischargeable capacity,
I.e. 15000 cubic metres, according to total flood protection, need about 30 tons of carbon dioxide extinguishing agent.Even if in silo coal storage compared with
Few, in the case that top real space is more than 15000 cubic metres, the ability of carbon dioxide exclusion combustible gas and oxygen still can be with
One layer " umbrella " is formed above coal, coal surface is covered in a long time, substantially reduce its fire risk.
The carbon dioxide extinguisher installation 80 of the present embodiment is provided with automatic, manual, mechanical emergency and starts totally three kinds of controlling parties
Formula：Automatic control mode：When temperature sensor 81 detects the temperature anomaly rising signals of+20 DEG C/min, to controller 82
