Compared with the prior art, in water mist jet flow injected by the fine water mist fire extinguishing equipment, the sum of the volumes of water particles with diameters smaller than 200 mu.m is not smaller than 90 percent of the total volume, the water-drop size of fine water mist is very small, and the fine water mist has a very large specific surface area, very high density and a very good smoke removing effect.
Description
Technical field
The utility model relates to a kind of fire extinguishing system, especially relates to a kind of fine mist fire-fighting equipment.
Background technology
Water spray fire extinguish system of the prior art mainly comprises fixed and the semi-fixed type system.Fixed water spray fire extinguish system, partly form by fire water pump house, wet type drench valve and high speed water mist shower nozzle and siamese fire department connection etc., during breaking out of fire, warnings such as fire detector that lays along power cable tunnel such as temperature sensing cable, the fireproof door that the fire compartment of breaking out of fire is closed in interlock cuts off, open electric contact drench valve in the corresponding fire compartment simultaneously, waterfog head ejects high-pressure water mist, to reach cooling, cool off, suffocate and finally to put out the purpose of fire in the fire compartment.Fixed water injection system has response rapidly, the advantage of good extinguishing effect, but number of devices such as waterfog head, drench valve and fire pump are many in system's composition, and investment is big, and has increased a large amount of daily management maintaining work.Simultaneously, because the increase greatly of fire-fighting wastewater flow rate, make draining pump and all corresponding increase of waste water sump in the electric power tunnel, fire pump room and draining pump house take up an area of big, have increased design, difficulty of construction.
The semi-fixed type water injection system and the fixed main distinction are not to be with fire pump in the system.During breaking out of fire, fire detector is reported to the police, and corresponding fireproof door is closed in interlock, simultaneously fire signal is delivered to relevant fire department.Fire Department sends fire fighting truck, by siamese fire department connection water is delivered in the tunnel from the outdoor fire hydrant water intaking by fire fighting truck, implements fire extinguishing by waterfog head.The semi-fixed type system is not owing to itself establish fire pump, so during fire, system can not automatic sprinkling fire-extinguishing, has lost the most opportune time that puts out initial fire disaster.
The fire-fighting principle of water injection system be by water smoke surface cool, suffocate and blocking radiant heat to reach fire extinguishing and to prevent the purpose that fire draws out.System utilizes high voltage power and special waterfog head, moisture is cleaved into the very little droplet of diameter, make it meet the gasification rapidly of heat back, produce very big action face, (1 premium on currency becomes steam to make heat absorption efficient reach maximum, need to absorb the heat of 335KJ), be that the burning surface temperature descends rapidly, reach cooling effect; Because fogdrop diameter is little, meet the heat back rapid evaporator expansion of water smoke (about more than 1640 times), effectively get rid of the air in the scene of a fire, and form screen around in the scene of a fire, intercept the outer air in the scene of a fire and import, and near the airborne oxygen content of dilution fire, make its generation reaction that suffocates; Studies show that, the heat that burning discharges, quite major part is transmitted in the space towards periphery with forms of radiation, the water smoke that water mist system produces is because fogdrop diameter is very little, can effectively absorb and intercept the burning things which may cause a fire disaster radiant heat, thereby safe escape and fire extinguishing personnel that can the help desk personnel rescue near the scene of fire, and resist the radiant heat spot fire that ignites effectively, effectively prevent spreading of fire.
In the conventional design, as the design of the water spray of main transformer, waterfog head generally be arranged in as far as possible protected object around and the top, in the hope of good envelope effect.It is less that but the electric power tunnel space compares, cable testing bridge is layered arrangement again, and the cable laying on every layer of crane span structure is also comparatively dense, the cable that multilayer is arranged has bigger barrier effect to spraying, as still with top or the side of nozzle layout of sprinkler at cable, certainly can not satisfy that standard is desired to make water smoke direct injection, covering, and the requirement of envelope multi-layer cable fully.
Summary of the invention
The purpose of this utility model is exactly the fine mist fire-fighting equipment that a kind of smoke abatement effect excellence of putting out a fire is provided for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of fine mist fire-fighting equipment, it is characterized in that, this fire extinguishing system comprises filter, water tank, supply-water pump, control valve for water pump, zone valve, waterfog head and warning device, described filter one end is connected with the water source through the water source valve, the other end is connected with water tank through pipeline, described supply-water pump one end is connected with water tank through pipeline, the other end is through pipeline join domain valve, described control valve for water pump is connected respectively with supply-water pump, zone valve and warning device through the signal of telecommunication, and described waterfog head is connected with zone valve through pipeline.
Be provided with the pump water inlet valve between described water tank and the supply-water pump.
Pressure sensor, pump discharge valve and feed water valve are set between described supply-water pump and the zone valve.
Pressure gauge and pressure switch are set on the described zone valve.
Described waterfog head is the open type fine mist spray head.
Described warning device comprises fire alarm control unit, smoke fire detector and cable formula heat fire detector, described fire alarm control unit is connected with control valve for water pump through the signal of telecommunication, and described smoke fire detector and cable formula heat fire detector are connected with fire alarm control unit through the signal of telecommunication.
Compared with prior art, the utlity model has following advantage:
(1) heavy pressure fine spray is under shower nozzle minimum working pressure power, and water smoke cumulative volume distribution Dv0.9 is less than 200 μ m, and promptly in the jet spray of shower nozzle ejection, diameter is not less than 90% of cumulative volume less than the water particle volume sum of 200 μ m;
(2) water droplet size of thin water smoke is very little, has very big specific area and very high density, and fine mist fire-fighting equipment mainly is to stamp out a fire by vaporization absorbing and cooling temperature effect and starvation smothering action;
(3) thin water smoke also has good smoke abatement effect; because thin water smoke specific area speed big, in light weight, that land in air is slow; long with flue gas time of contact, contact area is big; can absorb smog and poison gas in the scene of a fire in a large number; in fire extinguishing; can protect cable, electrical equipment not to be subjected to " secondary damage " of fire, make things convenient for evacuating personnel and strength of attack to implement to put out a fire to save life and property near burning things which may cause a fire disaster.
