Description

The fixed high-pressure water fog sprinkler
Technical field
The utility model belongs to fire plant.
Background technology
Alkyl halide (translated name breathe out dragon) fire extinguishing system is widely used a kind of efficient, low toxicity fire extinguishing system in the world wide, but because the use of halon extinguishing agent loss ozone layer greatly.1987 the United Nations's environmental protection pact " Montreal Convention " clearly propose: requiring countries in the world to eliminate to breathe out dragon (be alkyl halide, as 1211,1301 etc.) at the beginning of 21 century is the fire extinguishing system of extinguishing chemical.Therefore fire protection sector has very urgent demand to the novel fire-fighting system that can replace alkyl halide efficient, environment-friendly type both at home and abroad.
Except that alkyl halide, other is commonly used also has gas extinguishing systems such as carbon dioxide, inert gas, and these gas extinguishing systems are toxic or smothering action to human body, uses dangerously, and the scope of application is very limited.Along with to safety in production, requirement on environmental protection is more and more higher, adopt water to cause widely and pay attention to as the environment-friendly type fire product of firing-fighting medium.According to literature search and investigation, existing low pressure single fluid water spray fire extinguish system generally adopts centrifugal pump to drive, because operating pressure is low, water atomization is insufficient, and fire-fighting efficiency is lower, can not be used to put out electrical fire, and because water consumption is bigger, what cause after the fire extinguishing is water stain seriously polluted.
Fig. 4 is the liquid double-fluid water fog fire extinguishing system of calming the anger in the Nanjing Fire Fighting Material and Apparatus Factory development, and this system adopts high pressure nitrogen as power source, system works pressure 3.5MPa, and system architecture is simple.But because operating pressure is lower, water atomization is insufficient, and water consumption is bigger, and fire-fighting efficiency is low; Owing to use gas (nitrogen), the fire extinguishing of liquid (water) two-phase media, still have the shortcoming of gas extinguishing system poor stability, limited its application in a lot of occasions; Because its pipe network structure is single, add the gas cylinder finite capacity, its lasting attack time is short, and only is applicable to the part is carried out the fire-fighting protection among a small circle.
Fig. 5 is the middle pressure single fluid water fog sprinkler of the hydraulic pamp driving of Nanjing Fire Fighting Material and Apparatus Factory development; the operating pressure 3.5MPa of pump group; though this system has overcome gas-liquid double-fluid water fog fire extinguishing system poor stability; continue the short deficiency of attack time; but because the element operating pressure that adopts is lower, still exist water atomization insufficient, water consumption is bigger; the shortcoming that fire-fighting efficiency is not high, and the structure of its nozzle pipe network only is applicable to fire-fighting protection is carried out in one or more less zones.
