Description
Technical field
The invention belongs to fire fire extinguishing system technical field, relate to a kind of large-scale storage tank and spray powder extinguishing system without blind spot.
Background technology
Large-size chemical oil storage tank class fire can not be put out bring huge property loss and environmental pollution by society within the very first time, fire longer property loss burning time and environmental pollution more serious.Therefore, blow-off velocity installed to large-size chemical oil plant class storage tank fast, prevent fire resume combustion, comprehensive be necessary very much without the automatic ejecting extinguishing system of blind spot, and there is effective meaning.
This traditional large-scale storage tank fire extinguishing system, mainly contains foam class fire extinguishing system, gas fire extinguishing system, water system class fire extinguishing system, dry powder class fire extinguishing system, and movable type mainly contains fire fighting truck class, all adopts " point type " to spray without exception and carries out spraying medicine fire extinguishing.No matter be fire extinguishing system or fire fighting truck spraying medicine, all for unit carries out point type injection with each " shower nozzle ", medicament release rate is seriously restricted, thus cause medicament ejector to arrive the burning velocity of speed well below fire in storage tank of whole storage tank fire combustion front, for large-scale storage tank, particularly chemical industry oil plant class storage tank is once breaking out of fire, if extinguishing chemical is when storage tank breaking out of fire, the fire extinguishing of whole storage tank fire burning liquid level starvation can not be covered the very first time completely, burning things which may cause a fire disaster will be caused to suffocate instantaneously, oxygen and burning things which may cause a fire disaster is made to have gap to produce chain reaction, cause the burning that large-scale storage tank fire is more fierce further, incur loss through delay the best effective time of putting out storage tank fire.
Summary of the invention
For solving the delayed and not enough of existing fire extinguishing system and technology, the invention provides a kind of large-scale storage tank and spraying powder extinguishing system without blind spot.When the breaking out of fire of large-scale storage tank class, the fire extinguishing system of spraying dry powder without blind spot can be carried out to storage tank liquid level.This system, when detecting the condition of a fire, can spray powder extinguishing agent by " equidistant special fighting nozzle " very first time, and form complete covering instantaneously and to suffocate closing face, cover whole burning liquid level rapidly, starvation, stamps out a fire.
The present invention is realized by following scheme: large-scale storage tank sprays powder extinguishing system without blind spot, comprises drive medium, extinguishment control system, drive medium transfer pipeline, extinguishing chemical transfer pipeline, extinguishing chemical storage tank, powder extinguishing agent, control drive medium valve, the equidistant special fighting nozzle installed around whole tank wall.The control system of fire extinguishing system connects temperature sensing device by temperature sensing controller by pipeline and forms.When temperature sensing device detects the condition of a fire, signal moment is accurately sent to temperature sensing controller, open and control drive medium valve, by drive medium pipeline release drive medium to extinguishing chemical storage tank, abrupt release powder extinguishing agent, by the special equidistant fighting nozzle of series be connected with extinguishing chemical transfer pipeline, fast powder extinguishing agent is sprayed to scene of a fire fire extinguishing, formed fast without the complete cover type fire extinguishing of blind spot.Present system is simple to operate, and maintenance cost is low, can realize automatically starting putting out storage tank fire without blind spot fast, and extinguishing chemical release rate is unrestricted, blow-off velocity fast, and efficiency is high, efficient anti-resume combustion, when fire occurs, rapidly and efficiently can thoroughly put out storage tank fire.
