Abstract
The utility model relates to a self generation nitrogen gas fire extinguisher, which is mainly composed of a nitrogen gas reservoir (1), a nitrogen gas meter (2), an on-off controller (3), an air feeder (4), an oxygen and nitrogen separator (5) and a nitrogen feeder (6). When the air feeder is connected with the oxygen and nitrogen separator, the nitrogen gas is input into the nitrogen gas reservoir, the nitrogen gas reservoir is connected to the protected area through the nitrogen feeder, and when the nitrogen gas in the nitrogen gas reservoir is in leakage, the device can automatically supplement the nitrogen gas.
Description
The utility model belongs to the fire prevention field, is a kind of nitrogen extinguishing device, can be widely used in important industry and civilian occasion.
As everyone knows, fire is the formidable enemy of harm property and life, for the life and the production place of outbalance, people have adopted some fire extinguishing measures, and wherein inert gas fire-fighting system belongs to " green " fire extinguishing system of no quadratic loss, non-environmental-pollution, not life threatening.The needed fire-suppressant gas concentration of such fire extinguishing system is big, and gas itself is difficult for liquefaction, therefore, adopts the high pressure mode that extinguishing chemical is stored in a lot of gas cylinders usually in order to store a large amount of extinguishing chemicals.The storage of higher pressures mode is brought following shortcoming:
1) container, pipeline, valve that is used for gas storage and conveying etc. is withstand voltage and sealing requirements is high, and the equipment complexity is bulky.
2) gas unavoidably can revealed in the storage process for a long time, and the filling of gas need use special equipment just can carry out, and is difficult to therefore guarantee that fire extinguishing system is in serviceable condition all the time.
3) after the test and actual act of fire extinguishing system, need refill extinguishing chemical and just can make system recover normal.
The purpose of this utility model is to find to solve the scheme that the problem of leakage takes place nitrogen extinguishing agent extinguishing chemical in storage process, improves the reliability of fire extinguishing nitrogen system.
The purpose of this utility model is achieved in that connecing one on the nitrogen storage storage in succession overlaps the nitrogen gas generation device, and the nitrogen gas generation device is made up of air feeder, oxygen, nitrogen separator, and the nitrogen-rich gas outlet of oxygen, nitrogen separator links to each other with the nitrogen storage storage.One radon survey instrument is installed in the nitrogen storage storage, detect the leak case of nitrogen in the nitrogen storage storage, and with the direct information on off controller, on off controller is started or stoped the work of air feeder according to this information.If nitrogen amount is less than set amount in the memory, the nitrogen gas generation device will start additional nitrogen in the nitrogen storage storage, reach requirement up to nitrogen amount.The nitrogen storage storage links to each other with protected district by the nitrogen conveyer simultaneously, and when breaking out of fire, the work of nitrogen conveyer is sent nitrogen into protected district and implemented fire extinguishing.
Air feeder is used for air is sent to oxygen, nitrogen separator,, it can adopt air compressor or blower fan or other to pump wind devices, and the air that enters air feeder can draw gas in protected district, also can directly draw from atmosphere.Air feeder also can be installed in the import of oxygen, nitrogen separator, also can be installed in its outlet, if do like this, then needs at the nitrogen outlet and the oxygen outlet of oxygen, nitrogen separator a conveyer to be installed respectively.Oxygen, nitrogen separator are used for airborne oxygen and nitrogen relative separation, and it can be the equipment that gas separation membrane or molecular sieve constitute, and also can be can be with other equipment of oxygen in the air and nitrogen relative separation.The sealing of nitrogen storage storage is not had strict restriction, can adopt container, basement, above ground structure or any enclosure space as the nitrogen storage storage.The nitrogen conveyer can adopt anyly to be pumped wind devices or only is a gas communication control valve or hermatic door.
Spontaneous nitrogen nitrogen extinguishing device has following advantage:
1) stores the fire extinguishing nitrogen of q.s in the holder all the time, guaranteed the reliability of fire extinguishing.
2) the spontaneous nitrogen characteristic of extinguishing device, making does not have specific (special) requirements to the sealing of nitrogen memory, therefore can utilize various containers, basement, above ground structure or other spaces are as the nitrogen storage storage.
3) employing of oxygen, nitrogen separator makes extinguishing device have higher running efficiency, thereby the operating cost of device is lower.
4) nitrogen-rich gas is nontoxic, harmless, pollution-free, and non-conductive characteristic makes this spontaneous nitrogen extinguishing device can be used for putting out a fire to save life and property of various category-As, category-B, C class and electrical fire.
Accompanying drawing is the detailed composition and the workflow diagram of spontaneous nitrogen nitrogen extinguishing device, and it is by nitrogen storage storage (1), radon survey instrument (2), on off controller (3), air feeder (4), oxygen, nitrogen separator (5), nitrogen conveyer compositions such as (6).Its operation principle is as follows: after the nitrogen in the nitrogen storage storage (1) is revealed; radon survey instrument (2) is delivered on off controller (3) with the nitrogen reveal information; on off controller (3) starts air feeder (4); the gas of outside air or nitrogen memory (1) is delivered to oxygen, nitrogen separator (5); oxygen, nitrogen separator (5) are discharged to oxygen-enriched air outside the protected district; nitrogen-rich gas is sent in the holder (1) simultaneously, made that nitrogen amount increases in the holder.When nitrogen amount is increased to set numerical value, controller (3) will stop the operation of air feeder.When fire took place, the nitrogen that nitrogen conveyer (6) starts q.s in the nitrogen memory (1) was sent to conflagration area enforcement fire extinguishing.
When protected district hour, nitrogen storage storage (1) can not established (corresponding radon survey instrument (2) does not exist yet), the nitrogen that is used to put out a fire can be directly from oxygen, nitrogen separator.
Claims (6)
1. spontaneous nitrogen nitrogen extinguishing device; mainly form by nitrogen storage storage (1), radon survey instrument (2), on off controller (3), air feeder (4), oxygen, nitrogen separator (5), nitrogen conveyer (6); after being primarily characterized in that air feeder (4) and oxygen, nitrogen separator (5) being connected; make nitrogen be communicated to nitrogen storage storage (1), nitrogen storage storage (1) is communicated to the protected area by nitrogen conveyer (6).
2. the spontaneous nitrogen nitrogen extinguishing device described in the claim 1 is characterized in that air feeder (4) can be any exhaust equipments that send such as air compressor machine or blower fan.
3. the spontaneous nitrogen nitrogen extinguishing device described in the claim 1 is characterized in that air feeder (4) can adopt an import that is positioned at oxygen, nitrogen separator (5), also can adopt two rich nitrogen and oxygen rich gas outlets that lay respectively at oxygen, nitrogen separator (5).
4. the spontaneous nitrogen nitrogen extinguishing device described in the claim 1, it is characterized in that oxygen, nitrogen separator (5) can be membrane separation plant or other molecular sieves or any can be with the equipment of oxygen in the air and nitrogen separation.
5. the spontaneous nitrogen nitrogen extinguishing device described in the claim 1 is characterized in that nitrogen memory (1) can be the enclosure space of any kinds such as container, basement, surface structures.
6. the spontaneous nitrogen nitrogen extinguishing device described in the claim 1 is characterized in that nitrogen conveyer (6) can be any wind devices or gas communication valve or hermatic door pumped.
