Description
(1) technical field
The utility model relates to a kind of water mist fire-extinguishing nozzle that is used for navy submarine and naval vessel fire-fighting system, is the substitute products of water spray and haloalkane extinguishing system, is mainly used in submarine, field, naval vessel, also can be applied to fields such as other civilian merchant ship fire-fighting.
(2) background technology
The status of fire extinguishing system is very important in the efficient public security system on submarine and naval vessel, in order to put out accommodation fire in submarine and the naval vessel, water sprinkling fire-distinguishing system is set at present, although water sprinkling fire-distinguishing system can put out solid fire effectively, but exist the water for fire extinguishing amount big, put out kindling material single, to shortcomings such as oil fire, the fiery fire extinguishing effectiveness of cable are not ideal enough, and can produce than the havoc effect equipment in the cabin and equipment, be badly in need of it is updated.
Water Mist Fire Extinguishing Technique is good with its feature of environmental protection, fire extinguishing rapidly, water consumption is low, destructiveness is little and characteristics such as suitable face width, become international fire-fighting domain and paid close attention to one of focus of studying.Submarine and naval vessel are as the important force of naval, this invention will be filled up the blank of naval in this research field, make up environmental protection, safe and efficient, willing fire-fighting system, to improve submarine and naval vessel fire-fighting ability, security, reliability has important military significance.
Thin water smoke is the environment-friendly type fire-fighting technique of high speed development in recent years, and it suppresses the fire method with tradition compares except that having more foregoing advantages, very extensive at the type scope of fire in addition, comprising: category-A fire, category-B fire and appliance fire.The domestic and international research experience shows that thin water smoke has good insulation performance.
The extinguishing mechanism of fine water mist fire-extinguishing system mainly is cooling, suffocate inerting and additive effect.Its cooling effect shows: when water is broken down into many tiny water droplets, its surface area can increase greatly, evaporation time shortens greatly, utilizes the high-pressure water mist fire-extinguishing technology, and the more traditional fire-fighting technique of thin water smoke that is produced has bigger active area and heat exchange area.It destroys the heat feedback cooling flame surface of fuel, and droplet can penetrate flame simultaneously, can improve fire-fighting efficiency greatly.For example, 1 premium on currency from 20 ° of heats that rise to 100 ℃ of needs absorption 335kJ, is converted thereof into the heat that steam need absorb 2257kJ again.
Its inerting effect of suffocating shows that high-pressure water mist passes through evaporation, and the volume of water is increased to nearly 1700 times.It has diluted near the airborne oxygen of burning things which may cause a fire disaster, and the inerting firing-fighting medium has limited the outside transmission of burning things which may cause a fire disaster in this process, and the diffusion of heavy pressure fine spray not only can enter zone of origin but also can prevent the inflow of block.Relative extinction using gas, high-pressure fine water mist fire-extinguishing system does not require the space of complete closed.After the potential energy of heavy pressure fine spray fully discharged, complete burning things which may cause a fire disaster was ensconced in the steam of evaporation, so that fire can in seconds suffocate.Usually the concentration of oxygen is about 21% in the air, when the concentration of oxygen when the burning things which may cause a fire disaster space reduces to 16%～18% immediately, burning things which may cause a fire disaster can suppress to extinguish.
In the process of fire extinguishing, high-pressure fine water mist fire-extinguishing system also can produce some other fire extinguishing additive effect.Though they are directly fire extinguishing not, and fire extinguishing is had positive role.Heavy pressure fine spray has the cleaning function of smog, waste gas.This is scrubbed because soot particle, coal soot and the fine water droplet of burning are bonding.Thin in addition water smoke can also play certain shielding action, reduces burning things which may cause a fire disaster to the heat radiation of object on every side, stops the diffusion of fire simultaneously, and fire is worked the effect of blocking.
(3) summary of the invention
The utility model purpose provides the fire extinguishing sprayer that is used for submarine and naval vessel accommodation heavy pressure fine spray fire-fighting system.Critical component as fine water mist fire-extinguishing system; this device is installed in the submarine and naval vessel accommodation that needs protection; water under high pressure sprays to guard space through the high speed fine liquid particles that this device back forms certain spray angle, puts out solid combustible and general liquid combustible fire.
Little, the inner combustible of the bulk of submarine and naval vessel accommodation is more, is equipped with the multilayer bed, and the fire combustible is more complicated also, has both had solid combustibles such as bed clothes, timber, has combustibles such as cable and some oil product again.Different thin water smoke parameters such as fogdrop diameter, jet velocity etc. also have very big difference to the validity of different fire and different guard space internal states.In order not influence normal live and work, fine mist spray head can only be installed in the top of bin, and the multilayer bed blocks thin water smoke, is unfavorable for fire extinguishing.Existing fine mist spray head is the design of total flooding system, but finds that the fine mist spray head of total flooding design is difficult to put out solid fire, almost can not stamp out a fire when having shelter to exist from a large amount of fire extinguishing experiments.In addition because thin water smoke fogdrop diameter is very little, even the momentum of water droplet is very little under high-pressure situations, be difficult to reach combustible surface, particularly spreading of spray when big, the thin water smoke at edge can't reach the purpose of fire extinguishing because the gravity effect presents floating state.The utility model is used for reference the design philosophy of rocket engine ejector filler, adopt different spray nozzles Combination Design scheme, realized that a shower nozzle can produce 1-3 kind different thin water smoke parameters at the equal effective design of the fire that exists similar multilayer bed etc. that the situation of blocking arranged.
High-pressure water mist fire-extinguishing nozzle of the present utility model is by different nozzle combinations, and the thin water smoke that sprays at same shower nozzle has spray field parameters such as different jet velocities, fogdrop diameter in different jeting areas.The specific design method of different nozzle combinations is: the shower nozzle spraying area is distinguished according to spray angle, seen Fig. 1.The shower nozzle spraying area is divided into A, B, three zones of C, A district spray field parameter spreading of spray α
1, droplet average diameter d
1, downward jet velocity V
1, put out combustible fire under the shower nozzle; B district spray field parameter spreading of spray α
