Technical field
The present invention relates to tunnel Tobacco Control technical field, specifically a kind of spaced apart water mists tunnel Tobacco Control system.
Background technology
Tunnel is a hemi-closure space, comburant mostly is the high-molecular organic material etc. in gasoline, diesel oil and the automobile interior in motor vehicle, once breaking out of fire, the high temperature produced and poison gas are extremely difficult to be got rid of in time, great damage can be caused to the facility be in tunnel and personnel, therefore control fire and smoke spread, effectively smoke evacuation is very important engineering measure in tunnel fire-fighting.For major long tunnel, along length of tunnel direction, smoke vent is set at top or other positions, and smoke vent length direction offer a series of smoke vent opening transverse direction smoke evacuation be the one more effective tunnel Flue Gas Control Technology of generally acknowledging in the world.But due to the existence of stack effect when Longitudinal Wind in tunnel and fire, flue gas is constantly longitudinally spread to downstream along tunnel, causes smoke vent opening smoke exhaust efficiency very low, effectively cannot improve the living environment in tunnel.
Because water mists size droplet diameter is less, more common spray system has stronger stop, absorbs advection heat and photothermal effect, also can carry out effective compacting even put out burning things which may cause a fire disaster; Also there are filtration and cleaning action to flue gas in water mists dispose procedure simultaneously.But water mists cost is high, pipe-line system is also unsuitable long, water mists drop initial velocity is larger in addition, consequent drag force and the strong cooling effect to heat smoke thereof, easily cause disturbance to flue gas layer, affects personnel escape and rescue operation in tunnel and carry out.
Summary of the invention
The object of the invention is the defect existed for prior art, a kind of spaced apart water mists tunnel Tobacco Control system is provided, thus keep the Environmental security of adjacent sections, for evacuating personnel and fire suppression create safe space to greatest extent, personnel and vehicle only just need can arrive safety zone through of short duration movement.
A kind of spaced apart water mists tunnel Tobacco Control system, comprise fire cistern 1, fire pump 2 and be positioned at the fine mist spray head 3 in tunnel 6, water mists main 4, water mists arm 5, smoke vent 7 and smoke vent opening 8, described fire cistern 1 is connected with fire pump 2 by pipeline, and fire pump 2 is connected with the water mists main 4 arranged along tunnel 6 total length then; Water mists main 4 is connected with many water mists arms 5, and many water mists arms 5 are provided with electromagnetic valve 9 and are positioned at the fine mist spray head group 3 at top, tunnel 6, and described multiple fine mist spray head group 3 section gap is arranged; Top, tunnel 6 or side wall are provided with smoke vent 7, and be also provided with the smoke vent opening 8 of remote-controlled keying in described tunnel 6 every fixed range, smoke vent opening 8 is connected with smoke vent 7; Top, described tunnel 6 is provided with fire location sniffer.
Also be provided with control system in described tunnel 6, control system connects the valve on described fire detecting arrangement, electromagnetic valve 9, the air-valve of smoke vent opening 8, water pump 2 and its outlet pipe by sensor-based system.
Also be provided with drainage system in described tunnel 6, the exit of drainage system is connected with waste water pump house.
It is 10-14 rice that described one group of fine mist spray head group 3 covers length of tunnel, and the distance between adjacent fine mist spray head group 3 is not more than 350 meters.
The adjacent sprinkler spacing of described fine mist spray head group 3 is not more than 3.5 meters.
Be provided with the Smoke tower be communicated with smoke vent 7 at two ends, tunnel 6, in Smoke tower, be provided with smoke extractor exhaust fan.
Described smoke vent opening 8 is arranged along interval, length of tunnel direction, and adjacent smoke vent opening 8 spacing is 30-100 rice, and smoke vent opening 8 area is 2-6 square metre.
The advantage of the present invention's spaced apart water mists tunnel Tobacco Control system is: make full use of the features such as water mists cooling, good heat-insulation effect, water content consumption are few, reduce flue gas influence basin, effective control flue gas be diffused in be not more than 350 meters scope in, advantageously in smoke evacuation system Effec-tive Function, for personnel escape and fire attack provide good safe space; Meanwhile, compartment is arranged and is also greatly reduced the required fine mist spray head quantity arranged in the middle of tunnel, reduces water supply volume, is conducive to saving cost.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
In figure, 1 is fire cistern, and 2 is fire pump, and 3 is fine mist spray head, and 4 is water mists main, and 5 is water mists arm, and 6 is tunnel, and 7 is smoke vent, and 8 is smoke vent opening, and 9 is electromagnetic valve, and 10 is burning things which may cause a fire disaster.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.As shown in Figure 1, a kind of spaced apart water mists tunnel Tobacco Control system, comprise fire cistern 1, fire pump 2 and be positioned at the fine mist spray head 3 in tunnel 6, water mists main 4, water mists arm 5, smoke vent 7 and smoke vent opening 8, described fire cistern 1 is connected with fire pump 2 by pipeline, and fire pump 2 is connected with the water mists main 4 arranged along tunnel 6 total length then; Water mists main 4 is connected with many water mists arms 5, and many water mists arms 5 are provided with electromagnetic valve 9 and are positioned at the fine mist spray head group 3 at top, tunnel 6, and described multiple fine mist spray head group 3 section gap is arranged; Top, tunnel 6 or side wall are provided with smoke vent 7, and be also provided with the smoke vent opening 8 of remote-controlled keying in described tunnel 6 every fixed range, smoke vent opening 8 is connected with smoke vent 7; Top, described tunnel 6 is provided with fire location sniffer.
