Description
Technical field
The present invention relates to hard-wired fire-fighting equipment, especially a kind of is the thin water smoke automatic fire extinguishing system of fixed high-pressure of feature with the water hydraulic components.
Background technology
Put out electrical fire and oil fire at present and mainly adopt Kazakhstan dragon (Halon) fire extinguishing system.But breathe out the used extinguishing chemical CF of imperial fire extinguishing system
3Br (Halon 1301), CF
2BrCl (Halon 1211) has certain toxicity, and atmospheric ozone layer is had serious destruction, so united nations environment protection pact---and " Montreal Convention " (1987) have explicitly called in the imperial fire extinguishing system in replacement Kazakhstan in early years 21st century.The alternative system of Tui Chonging just comprises fine water mist fire-extinguishing system in the world.High-pressure fine water mist fire-extinguishing system is the wherein a kind of of fine water mist fire-extinguishing system, compare with other two kinds of fire extinguishing systems such as the thin water smokes of biphase gas and liquid flow with the thin water smoke of low pressure, the water yield that it consumes still less, the spray velocity height, it is stronger that thin water smoke penetrates scene of a fire ability, fire extinguishing rapidly thoroughly, scene of a fire ashes can resume combustion, can put out the inextinguishable oil fire that covers of other two kinds of water mist systems.So being a kind of Kazakhstan dragon of fire extinguishing effectiveness excellence, high-pressure fine water mist fire-extinguishing system substitutes fire extinguishing system.
But the operating pressure of high-pressure fine water mist fire-extinguishing system is generally more than 10MPa, and traditional water sprinkling fire-distinguishing system and water spray fire extinguish system pressure is the highest can only reach about 3MPa, the required basic pressure of the thin direct high-pressure atomization of water smoke of distance requires very far away, what sprayed is the globule of the bigger big flow of diameter, therefore in fire extinguishing procedure, a large amount of article that do not catch fire also can be badly damaged because being subjected to the big flood immersion, causes unnecessary loss; The globule that diameter is bigger also can cause the fiery phenomenon of spattering of fluid, can not be used for putting out oil fire.
Summary of the invention
To be that development is a kind of can produce the above High-Pressure Water of 10MPa in the present invention, and High-Pressure Water is carried out pressure and direction control, is the thin water smoke automatic fire extinguishing system of fixed high-pressure of feature with the water hydraulic components.
The technical solution used in the present invention is as follows:
It comprises the detection control system that is connected with circuit; the water supply electromagnetic valve; threephase asynchronous; at least one is arranged in the fire protection zone and is independent of the heat detector of a plurality of open type heavy pressure fine spray nozzles or/and smoke detector; a plurality of pure water hydraulics solenoid directional control valves are connected with a plurality of open type heavy pressure fine spray nozzles respectively; the pure water hydraulics solenoid directional control valve is connected with the high-pressure outlet end of pure water hydraulics unloading overflow valve with the water hydraulic pump that is driven by threephase asynchronous, and the separator that drainage valve and water supply electromagnetic valve are housed is connected with the low-pressure inlet end of water hydraulic pump through accurate filter with water tank.
Said water hydraulic pump is for exporting 7 plungers or the 9 plunger positive displacement water hydraulic pumps of the above High-Pressure Water of 10MPa.The pure water hydraulics unloading overflow valve is for carrying out the pure water hydraulics unloading overflow valve that 10MPa goes up high-pressure adjusting and overload protection to system.The pure water hydraulics solenoid directional control valve is for going up the pure water hydraulics solenoid directional control valve that High-Pressure Water carries out break-make control to 10MPa.Said open type heavy pressure fine spray nozzle is 7 hole open type heavy pressure fine spray nozzles of 6 spray orifices of circumferential distribution and 1 spray orifice of central distribution, makes the atomizing cone angle of whole nozzle enlarge, and the flame failure protection zone significantly increases.
Be arranged in the heat detector or the smoke detector that distribute in the protection zone, when sensing the fire generation, the detection control system is reported to the police, and sends the signal controlling threephase asynchronous and makes whole system work.Threephase asynchronous drives the water hydraulic pump rotation; output is greater than the High-Pressure Water of 10MPa; arrive open type heavy pressure fine spray nozzle by the pure water hydraulics solenoid directional control valve; drip the footpath less than the thin water smoke haze of the dense high speed of 100 μ m by fully being atomized into after the nozzle ejection; about 1700 times of volumetric expansions; can implement to put out a fire, suppress the fire-fighting protection of various ways such as fire, control fire, cooling to object of protection; put out a fire by mechanism such as efficient absorbing and cooling temperature, the scene of a fire that suffocates, radiation-inhibiting heat, reach good fire extinguishing effect.
The native system water consumption is little, is particularly suitable for putting out places such as grain depot, library, museum, paper mill, chemical plant and requires the low category-A solid fire of water damage; The thin water smoke fogdrop diameter that native system produces is little, can not cause the fiery phenomenon of spattering of fluid, and fluid is had emulsification, also is particularly suitable for the category-B liquid fire in places such as kitchen, hotel, gas station, oil storage tank is effectively protected and put out a fire; The thin water smoke that native system produces insulate, and therefore also can effectively put out the electrical fire of High-Voltage Electrical Appliances (as transformer), electronics rapidly.Simultaneously, the native system sanitation and hygiene, nontoxic, alternative existing Kazakhstan dragon (Halon) fire extinguishing system that atmospheric ozone layer is had destruction; Native system also is particularly suitable for the fire extinguishing of aircraft, can create 3～5 minutes valuable escape time for the passenger; Native system pressure height, the also fire-fighting fire extinguishing of suitable skyscraper.
