The specific embodiment
With reference to the accompanying drawings a kind of Novel double-tube formula two-phase flow fire extinguishing system described in the utility model is described further:
As Fig. 1, shown in 2, a kind of for Novel double-tube formula two-phase flow fire extinguishing system, comprise System Control Center 3, intelligence nitrogen gas generating system 2, electrical cable 31, steam line 21 and guard plot 4, described System Control Center 3 is connected with intelligent nitrogen gas generating system 2 by electrical cable 31, simultaneously, System Control Center 3 is also connected with respectively end-probing device 42 and external control assembly 32 by electrical cable 31, described end-probing device 42 can be smoke detector, heat detector, oxygen concentration detector etc., described external control assembly 32 includes venting indicator lamp 51, emergency start-stop press-button 52, input/go out module 53 and audible-visual annunciator 54, this described system also comprises intelligent water supply system 1, water supply line 15 and two-phase flow shower nozzle 41, described System Control Center 3 is by electrical cable 31 difference Parallel Control intelligent water supply system 1 and intelligent nitrogen gas generating systems 2, described intelligent water supply system 1 is parallel on the two-phase flow shower nozzle 41 in guard plot 4 by steam line 21 and water supply line 15 respectively with intelligent nitrogen gas generating system 2, on the water supply line 21 being connected between described intelligent water supply system 1 and guard plot 4, establish successively respectively pressure-regulating valve I 11, electrical ball valve 12, Pressure gauge I 13 and flowmeter I 14, meanwhile, electrical ball valve 12 and flowmeter I 14 are connected to System Control Center 3 by electrical cable 31, and are controlled by System Control Center 3, on the steam line 21 being connected between described intelligent nitrogen gas generating system 2 and guard plot 4, be respectively equipped with pressure-regulating valve II 22, select control valve 23, pressure switch 24, Pressure gauge II 25 and flowmeter II 26, meanwhile, select control valve 23, pressure switch 24 and flowmeter II 26 to be connected to System Control Center 3 by electrical cable 31, and controlled by System Control Center 3.
When System Control Center 3 detects end-probing device 42 signals (as smoke detector, heat detector, oxygen concentration detector etc., conventional requirement is fire while meeting warning and occurs) on guard plot 4, start audible-visual annunciator 54.Simultaneously, System Control Center 3 starts controls intelligent nitrogen gas generating system 2 and intelligent water supply system 1, open electrical ball valve 12 simultaneously and select control valve 23, and start, to the selection control valve 23 on the electrical ball valve on water supply line 15 and flowmeter I 14 and steam line 21, pressure switch 24 and 26 monitoring of flowmeter II, to guarantee normal for nitrogen and water supply.This fire extinguishing system adopts with nitrogen pressurization mixes water, produces water particulate, from spray orifice ejection, forms mist cover, reaches cooling and object oxygen barrier; After the atomization of water particulate, even if the water of same volume can make surface area increase, and the increase of surface area, easier heat absorption, cooling combustion reaction, meanwhile, absorbs hot water particulate easily to vaporize, and volume increases approximately 1700 times.Due to the generation of water vapour, both diluted near the oxygen concentration of flame, the combustion reaction that suffocated, has effectively controlled again heat radiation.Meanwhile, the nitrogen that enters guard plot 4 with water smoke is replaced the air of internal environment in a large number, makes oxygen content fast reducing, also will speed up effective control fire, improves fire extinguishing effectiveness.Later stage water smoke, along with temperature reduces, by sedimentation and the thing surface that catches fire, penetrates into inside, realizes fire extinguishing object completely, prevents secondary resume combustion.
