Abstract
Disclosed is a water mist fire extinguishing system of a power plant electronic equipment room. The fire extinguishing system is characterized by comprising a water mist fire extinguishing device, an automatic control isolating valve, a pipeline, a spray head, a linear optical fiber temperature-sensing fire detecting system and a fire extinguishing linked disk, wherein the linear optical fiber temperature-sensing fire detecting system is connected with the fire extinguishing linked disk, the fire extinguishing linked disk is connected with the water mist fire extinguishing device and used for controlling the same, and the water mist fire extinguishing device is sequentially connected with the automatic control isolating valve, the pipeline and the spray head. The water mist fire extinguishing system with high fire extinguishing efficiency and low maintenance cost is a green fire extinguishing agent, has fine environment-protective performance, is harmless to ozone layer, and can not cause greenhouse effect.
Description
Technical field
The utility model belongs to power distribution device (dish, cabinet) fire prevention field.
Background technology
All there are power distribution station, electric room, relay bungalow in thermal power plant (nuclear power plant).These places for many years using gases as extinguishing chemical.Extinction using gas, otherwise consumption is big, and investment is high, maintenance cost is high, needs secondary canned; Toxic for human body, equipment there is corrosiveness, perhaps to ozone layer existence destructiveness to a certain degree.In powerplant control room periphery place, as electric room, relay bungalow and engineer station's using gases, considering often has the people, often adopts IG541 etc., and the gas place of production, can point lack, and price is high.
The early stage research and development of thin water smoke are used for boats and ships, in recent years, begin to be applied to industries such as communication, metallurgy.Still there is not the application precedent in power industry especially powerplant control room zone.Big performance even the damage that influences electrical equipment of issuable secondary disaster-ambient humidity forms a kind of notional yoke, the popularization of serious restriction, the thin water smoke of constraint.
The utility model content
Technical problem to be solved in the utility model is to utilize the advantageous demineralized water condition of power plant, brings into play the technical advantage of thin water smoke, thoroughly replaces gas, exempt that the extinction using gas secondary is canned, deep-seated fire, maintenance bother the fire-fighting efficiency height.
For solving the problems of the technologies described above, the utility model provides a kind of power plant electric room fine water mist fire-extinguishing system, it is characterized in that: comprise fine spray extinguisher, control isolating valve, pipeline and shower nozzle, linear optical fiber temperature-sensing fire detecting system, fire extinguishing interlock dish automatically, linear optical fiber temperature-sensing fire detecting system connects fire extinguishing interlock dish, fire extinguishing interlock dish connects the control fine spray extinguisher, and fine spray extinguisher connects automatic control isolating valve, pipeline and shower nozzle successively.
Fire extinguishing interlock dish also is connected with air suction type smoke detection system, and this device sensitivity is adjustable, and its effect is the generation of effectively confirming fire.Linear optical fiber temperature-sensing fire detecting system and the synergy of air suction type smoke detection system, form " with " logical relation, realize discovery, location and accurately assert fire, send fire signal and give the interlock dish of putting out a fire.
Compare with traditional gas extinguishing system, the utlity model has following advantage:
1 extinguishing chemical is gathered materials on the spot, and power plant itself can provide, and can save the multi-filtering device of water supply pipe.
2 to need not secondary canned, can realize uninterrupted protection.
3 fast speed control fire, fire-fighting efficiency height, the water yield are 1/10th of traditional water sprays.
4 securities are good, and are harmless to personnel, and often the someone does not limit the unfavorable factor of use.
Can resume production fast after 5 fire extinguishings.
6 green extinguishing chemicals, good environmental protection, harmless to ozone layer, can not produce greenhouse effects.
7 maintenance costs are low
8 reduce smog toxicity, improve the visibility of best-effort path.
9 need not between big fire-fighting special use.
10 pairs of rooms do not have airtight requirement.
11 no resume combustion.
12 good electrical insulation properties guarantee electrical equipment safety.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
With reference to accompanying drawing, fine spray extinguisher 4 connects each dish cabinet unit 7, the optical fiber 8 of linear optical fiber temperature-sensing fire detecting system 2 inserts each dish cabinet unit, linear optical fiber temperature-sensing fire detecting system 2 connects fire extinguishing interlock dish 3, fire extinguishing interlock dish 3 connects fine spray extinguisher 4, and fine spray extinguisher connects automatic control isolating valve 6, pipeline and shower nozzle 9 successively.
Fire extinguishing interlock dish also is connected with air suction type smoke detection system 1.
During use; the DW system demineralized water system 5 of fine spray extinguisher and power plant self is connected; promptly draw from sweet-water tank and insert main building, network control building or switch control building by a pipeline; power distribution cabinet in each room is pressed column split; every group can comprise several cabinets; be a detection, fire extinguishing dish cabinet unit, the many stainless steel tubes that fine spray extinguisher is drawn insert the some dish cabinets unit that needs protection.The optical fiber of linear optical fiber temperature-sensing fire detecting system is inserted each dish cabinet unit, when in certain dish cabinet unit during breaking out of fire, send alarm signal by linear optical fiber temperature-sensing fire detecting system and automatic warning of air suction type smoke detection system, after postponing a period of time, by predefined program, the location catches fire and coils the cabinet unit, send enabling signal, open corresponding automatic control isolating valve, start fine spray extinguisher, quick extinguishing.
Claims (2)
1. power plant's electric room fine water mist fire-extinguishing system, it is characterized in that: comprise fine spray extinguisher, control isolating valve, pipeline and shower nozzle, linear optical fiber temperature-sensing fire detecting system, fire extinguishing interlock dish automatically, linear optical fiber temperature-sensing fire detecting system connects fire extinguishing interlock dish, fire extinguishing interlock dish connects the control fine spray extinguisher, and fine spray extinguisher connects automatic control isolating valve, pipeline and shower nozzle successively.
