Abstract
The invention provides an ultrafine dry powder extinguishing method for a high-rack stereoscopic warehouse. The area of the warehouse is divided into fire extinguishing subareas and rectangular fire extinguishing units; ultrafine dry powder extinguishing dust cloud generating devices are arranged; dedicated fire extinguishing agent spraying pipelines are mounted along a goods shelf column direction and are two fire extinguishing agent spraying main pipes parallelly laid against the lower surface of a bottom plate of an upper goods shelf, and a horizontal outer side of each main pipe is connected with a spraying branch pipe; and the spraying branch pipe is provided with downward sprinkling nozzles. During a fire hazard, an automatic detection system receives a fire hazard signal and then starts the fire extinguishing devices after identifying, determining and confirming the fire hazard signal so as to release a fire extinguishing agent, and related linkage equipment is started and stopped in linkage; gas-liquid two-phase flow of ultrafine dry powder and inert gas is sprayed to an on-fire position or a to-be-protected area through the dedicated fire extinguishing agent spraying pipelines, and a mixture of ultrafine dry powder and inert gas is uniformly sprayed to cover the surface of a to-be-protected substance; and thus, fire extinguishing is realized. According to the invention, multi-point formation of uniform sprinkling through linear long-distance multi-sprinkling nozzles is realized; the dust cloud of the fire extinguishing agent can penetrate a fire scene at a certain designed kinetic energy, and minimum usage amount of the fire extinguishing agent and an optimal fire extinguishing effect are realized.
Description
Technical field
The invention belongs to the fire-fighting fire extinguishing technical field, relate in particular to a kind of overhead stereo garage ultra-fine dry powder extinguishing method.
Be applicable to that the individual layer floor height is high, volume is large; The shelf continuous length is long, highly high and arrange intensive; The storing products kind is many, quantity is large; The overhead stereo garage that the operation automaticity is high is used.
Background technology
Along with the develop rapidly of Chinese national economy, the individual layer floor height is high, volume is large; The shelf continuous length is long, highly high and arrange intensive; The storing products kind is many, quantity is large; The high overhead stereo garage of operation automaticity occurs in a large number.In case such building breaking out of fire, fire spreading speed is fast, the difficulty of putting out a fire to save life and property is large.Were it not for very effective fire-fighting equipment, fire will cause very serious consequence.
The fire protection design that how to carry out this type of storehouse is a new problem, and not having ripe experience both at home and abroad can be for reference.Domestic and international existing fire extinguishing system, iron the existing fire extinguishing systems such as most IG541, heptafluoro-propane Fm200, hot aerosol, common dry powder such as water, water spray, foam, carbon dioxide, alkyl halide (1211,1301), cigarette, all can't be directly applied for overhead this specific environment of three-dimensional storehouse.
Such as the fire extinguishing that alkyl halide, carbon dioxide, cigarette iron to the greatest extent, gas extinguishing system, the hot aerosol fire extinguishing system such as heptafluoro-propane are only applicable to the total flooding place, clean guard space should not be greater than 2000m
3And with respect to overhead stereo garage m up to ten thousand easily
3, even hundreds of thousands m
3Storage capacity, just cannot use at all.
And the large space fire extinguishing means such as water cannon, foam monitor, powder fire monitor because shelf are high and intensive, are blocked mutually, cannot use in this type of place.
Successively attempted water spraying fire-extinguishing system, froth fire extinguishing system, high-pressure fine water mist fire-extinguishing system and superfine dry powder fire-distinguishing system in this type of place both at home and abroad, effect is all undesirable.
Such as water spraying fire-extinguishing system, froth fire extinguishing system.At first, a large amount of detest water goods and materials, water funk goods and materials are arranged in the stock of a lot of storehouses, can not use; Secondly, a large amount of pipelines, shower nozzle that layering is installed affect the operation of piler and even the logistics of whole warehouse; The load that brings to shelf behind the whole pipe network water-filling is very large, so that the design of shelf must additionally increase the weight of.
High-pressure fine water mist fire-extinguishing system.The big fire of going out of thin water smoke is easy, the little fire difficulty of going out; Go out B, C class fire is easy, the category-A fire difficulty of going out, and particularly smoldering fire is more difficult; Can not guarantee equally also to have the drawback of a large amount of pipe networks to detesting the water stain-free impact of water, water funk protection goods and materials.
Superfine dry powder fire-distinguishing system is as adopting pipe network, and equipment is huge, pipeline is long exceeds the ultimate range that ultra-fine dry powder can effectively carry and can't use.And present generally employing is many tools layering suspension type fire extinguishing system, but there is following problem in this fire-fighting mode: when the spacing between the shelf is less than 40cm back-to-back (distance of most of storehouses is worth less than this), ultrafine dry powder extinguishing installation commonly used is not put, and special-shaped device extinguishing ability is affected, more crucial is, the tunnel side of piler, forklift-walking can't suspension arrangement, otherwise affects the operation of equipment; And be hanging to the device of opposite side, and when on the shelf goods being arranged, formation is blocked, and extinguishing chemical is difficult to effectively arrive this side, and fire prevention of this one side just becomes blank blind area so.
In sum, lack the pointed extinguishing method that is applicable to overhead three-dimensional storehouse in the prior art.
