Abstract
The invention discloses a temperature feedback type water spray fire-extinguishing system and device. The temperature feedback type water spray fire-extinguishing system and device comprise ultrasonic water spray nozzles, an information processor, a control device, a water pump and an alarm device. Each ultrasonic water spray nozzle is provided with a temperature sensing device, a distance sensing device and an installation support. When a fire occurs, the temperature sensing devices and the distance sensing devices send collected parameters to the information processor, and meanwhile, the alarm device gives out an alarm signal. After analytical calculation, the information processor obtains the best water spray particle size and then gives out an order to the control device. After the control device obtains the order, the water pump is started, pump pressure is adjusted, and then water pressure is adjusted. Meanwhile, the ultrasonic water spray nozzles are opened, the ultrasonic frequency of the ultrasonic water spray nozzles is adjusted, and then the water spray particle size is adjusted comprehensively, thereby reaching the best value. In addition, according to the fire behavior, the the water spray particle size can be adjusted constantly, so that the fire is extinguished efficiently; and when the fire is put out, the temperature feedback type water spray fire-extinguishing system stops fire-extinguishing work. Compared with a gas fire-extinguishing system widely used currently, the temperature feedback type water spray fire-extinguishing system and device have the advantages of being safe and cheap. Meanwhile, usage of chemical substances such as halon gas can be avoided, and thus the ozone sphere and the environment are not damaged.
Description
Technical field
The present invention relates to mist fire-fighting field, in particular to a kind of Temperature Feedback formula water fog sprinkler and device.
Background technology
Fire extinguishing system may often be such that machine room, tunnel or stores the part must having in the buildings that easily breaking out of fire is but not easily put out a fire such as important substance or place.At present, we mainly adopt gas extinguishing system to put out a fire, but gas extinguishing system exists shortcomings, as, in confined space, the misoperation of gas extinguishing system usually can threaten the life security of staff；And in emergency circumstances fire extinguishing needs evacuation personnel when starting, this can delay attack time；The more important thing is, gas extinguishing system commonly uses halogenated hydrocarbon chemical substance (as breathed out dragon gas), and containing a large amount of chlorine and bromine in this kind of chemical gas, chlorine and bromine decomposite the free radical of chlorine, bromine under effect of sunlight, and then cause a series of destructive chain reaction, produce to destroy to earth's ozone layer, reduce ozone concentration, produce ozone hole.And breathe out dragon gas and can retain many decades in an atmosphere, the destruction of ozone layer is continued even longer time decades especially by it in stratosphere.As can be seen here, gas extinguishing system not only threatens the life security of staff, is unfavorable for timely fire extinguishing, more can produce ozone layer to destroy greatly, ecological environment is produced damaging influence.
In recent years, Water Mist Fire Extinguishing Technique is subject to the extensive concern of researcher gradually.Compared with extinction using gas technology, Water Mist Fire Extinguishing Technique has safety, cheap advantage, simultaneously it can be avoided that use chemical substances such as such as breathing out dragon gas, ozone layer and environment is not destroyed.And, research shows that water mists has good fire-extinguishing benefits: generally water mists water droplet size is little, surface area big, thus the surface film thermal conductance of water droplet is relatively big, and in high temperature environments, water droplet can rapid vaporization and then heat absorption；Simultaneously by thermodynamics it can be seen that the vaporization latent heat of phase change of water is up to 2280K/J Kg, thus substantial amounts of heat during vaporization, can be absorbed, reduce the temperature in the scene of a fire；And water droplet vaporization, water mists is quickly turned to steam and then the oxygen concentration being effectively reduced in space, is conducive to fire extinguishing；In addition, the volume of steam is about 1700 times of aqueous water volume, therefore water mists enter in flame and then be transformed into steam after due to volumetric expansion will reduce flame entrainment into air (oxygen) amount, thus dilution oxygen concentration reach fire extinguishing purpose.Generally, can water smoke high-efficiency gasification and then effectively fire extinguishing is closely bound up with water smoke particle diameter, intensity of a fire size, flame temperature etc., but tradition fine water mist fire-extinguishing system generally but can only eject the water smoke of single particle size, so just many defects are produced, as when the intensity of a fire is relatively big, flame temperature is higher, water smoke particle diameter be likely to less than normal, the globule is just gasified before being introduced into flame, extinguishing effect thus be substantially reduced；And when the intensity of a fire is less, flame temperature is relatively low, water smoke particle diameter is likely to bigger than normal, water smoke can not fully gasify and then affect extinguishing effect, and equipment even can cause the harm such as marshy land when electrical equipment is put out a fire.
Summary of the invention
For solving the problem existing for prior art, the invention provides a kind of Temperature Feedback formula water fog sprinkler and device.
The technical solution adopted in the present invention is: Temperature Feedback formula water fog sprinkler and device, including Ultrasonic wave spray nozzle, message handler, control device, water pump, holding wire, water-supply-pipe, water source, stand-by power supply, extraneous power supply, conductor wire, alarm device.Described Ultrasonic wave spray nozzle is provided with temperature sensing device, distance sensing device and mounting bracket.Described Ultrasonic wave spray nozzle, temperature sensing device are connected with message handler by holding wire with distance sensing device；Described water pump is connected with control device and message handler by holding wire；Described stand-by power supply enables when extraneous power supply is invalid；Described alarm device can send alarm signal when there is the condition of a fire.
As preferably, the parameter collected is transferred to message handler by described temperature sensing device and distance sensing device, message handler obtains best water smoke particle diameter after calculating by analysis, and then send instruction to control device, control to regulate water pump after device obtains instruction and then regulate hydraulic pressure, carry out comprehensive adjustment water smoke size by the ultrasonic frequency of adjustment Ultrasonic wave spray nozzle so that it is reach optimum, and can constantly adjust the size of water smoke particle diameter according to the condition of a fire simultaneously.
As preferably, under different fields of employment, the water fog particle particle diameter set by described message handler is different, water smoke particle diameter to make water smoke energy high-efficient gasification fire extinguishing and do not endanger the object protected, as in the place have electrical equipment particle diameter at 20～60 μm；In storage of oils place, particle diameter is 50～150 μm；In the precision instrument places such as machine room, particle diameter is 10～30 μm.
As preferably, described Ultrasonic wave spray nozzle is arranged on the wall of field of employment by mounting bracket and can rotate around mounting bracket.
As preferably, described Ultrasonic wave spray nozzle setting height(from bottom) should, at 2.5～5m, need when exceeding this scope suitably to reduce water smoke particle diameter, because water smoke has the phenomenons such as fusion in the process of ejection.
As preferably, the radius coverage area of described single Ultrasonic wave spray nozzle is 0.8～1.5m.
