Abstract
A water-resistant N2 supplying system able to support human respiration is composed of the N2 supplying pipeline and O2 detector in an enclosed space, O2 control unit connected to said O2 detector, N2 generator, and decompressing unit connected to said N2 generator for supplying N2 into said enclosed space via pipeline. As the content of O2 in air is 14-16%, it can not support combustion but can support human respiration to minimum.
Description
Technical field:
The present invention relates to the technical field of fire prevention system, a kind of specifically interior air composition of enclosure space that makes is not supported burning, and the while is the fire prevention nitrogen supply system of supporting human breath again.
Background technology:
The fire-fighting system of selling on the market generally all is made up of detection and warning system and fire extinguishing system; fire alarm system plays induction and reports to the police when fire takes place effect; fire extinguishing system stamps out a fire then; this class fire extinguishing system can be divided into several big classes; as gas; foam; dry powder and water fire-extinguishing system; the detecting head of detection and warning system can be divided into temperature-sensitive; sense cigarette and flame probe; wherein be used for the most generally with sense cigarette probe; this type of fire-fighting system has the shortcoming of following aspect: first; all be to survey the fire of having lighted earlier; and then implement to put out a fire; thereby can only reach and disappear; rather than it is anti-for purpose; when fire extinguishing; protected property; even life; destroyed; second; in the fire extinguishing system that with water is the fire extinguishing meson, as water sprinkler system when discharging, to the destruction that protected property caused; often also big than the destruction that fire caused; the 3rd, the probe of detection and warning system is particularly felt the possibility that the cigarette probe all exists wrong report; and cause the fire extinguishing system mistake to discharge; the 4th, a lot of gas extinguishing systems are difficult to accomplish effective fire extinguishing when discharging, and harmless; the 5th; dry powder and froth fire extinguishing system can damage equipment and environment when discharging, and the 6th, the substitute extinguishing chemical of the Kazakhstan dragon of chemical composition is much arranged; as heptafluoro-propane commonly used; though itself is nontoxic, at high temperature the byproduct that is produced is harmful, the 7th; though the carbon dioxide system fire extinguishing effectively; but the people is choked to death, and gas itself also is dangerous material because of being gases at high pressure; the 8th; because the water yield of water sprinkler system is limited, after exceeding its design water yield, just can not put out a fire.
Summary of the invention:
The object of the present invention is to provide a kind of fire prevention nitrogen supply system of supporting human breath, it can provide a closed environment of not supporting fire burns, and this environment can be supported human body respiration by bottom line again.
