Description
Technical Field
The invention relates to a water mist fire extinguishing device, in particular to a normal-pressure water mist intelligent fire extinguishing device.
Background
With the continuous progress of science and technology and the increasing improvement of life quality of people, after the basic life problems are solved, the safety problem is increasingly emphasized by people. In the active safety system, a smoke alarm, a temperature alarm, an infrared alarm, a combustible gas alarm and the like are arranged; among passive safety systems are fire hydrants, fire doors, fire extinguishers, water mist fire extinguishing systems, etc.
In a passive safety system, a water mist fire extinguishing system is always regarded as an efficient fire extinguishing apparatus, and is subdivided into high-pressure water mist, medium-pressure water mist and low-pressure water mist according to the supply pressure of fire extinguishing liquid of the water mist fire extinguishing system. The supply water pressure P of the high-pressure fine water mist is more than or equal to 3.5MPa, the supply water pressure P of the medium-pressure fine water mist is more than or equal to 1.2MPa and less than 3.5MPa, and the supply water pressure P of the low-pressure fine water mist is less than 1.2 MPa; high-pressure water mist is undoubtedly the best choice in terms of fire extinguishing effect, and the high-pressure single-fluid water mist fire extinguishing system is suitable for extinguishing A-type, B-type, C-type and electric fires. Due to the advanced fire extinguishing mechanism, the fire extinguishing agent is not limited by places, and can be applied to land, sea and space. However, since the water supply to the high pressure water mist fire suppression system is high pressure, it is also very expensive to produce, manufacture, install, use, etc. The 10MP pressure is also an unsafe factor, and the realization of follow-up target fire extinguishing is also very difficult. Although the low-pressure water mist has low water pressure and lower manufacturing cost compared with the high-pressure water mist, the low-pressure water mist needs the intervention of a booster pump to increase the supply pressure in the face of the supply of a common water source, so that the use requirement of the low-pressure water mist is met; the low-pressure pumps are easy to generate the phenomenon of mutual pressure cancellation when working simultaneously, so that the low-pressure water mist is limited in use places and is generally applied to common parts for water spraying such as diesel generator rooms, cable tunnels, electric fuel oil boiler rooms and the like; moreover, the protection object of the low-pressure water mist fire extinguishing system is not greatly different from that of a water mist fire extinguishing system, and more water consumption is needed, but the cost of a pipe network and a spray head of the low-pressure water mist fire extinguishing system is higher than that of water mist, particularly, the requirement of the spray head on the water quality is high, and the later operation and maintenance cost is also high.
From the above description, it is known that the low pressure water mist is not common in use, and the pressure of 1.2MPa is very large for general use, and it is not suitable to arrange a pressurizing device in some places or to modify the fire extinguishing system in places, such as a carriage, a wooden bookstore, etc. In similar locations as described above, conventional water mist fire suppression systems are not applicable. According to the national standard requirement and the water mist fire extinguishing principle, a certain amount of water mist is generated in a mode without water source pressure and has certain spraying capacity, so that the fire extinguishing requirement can be met, and the trouble of water source pressure can be avoided.
