Abstract
A fire extinguishing method features that the nitrogen gas separated from air by air separator is used as the fire-extinguishing chemical, which is delivered via pipeline to the fire-extinguishing system for isolating flame from air.
Description
Technical field
Patent of the present invention relates to a kind of extinguishing method, particularly a kind of use industrial nitrogen, and be stored in the processing pipe network by pipeline and spurt extinguishing method as firing-fighting medium.
Background technology
Use inert gas (as carbon dioxide, argon gas etc.) method for extinguishing fire to be at present; utilize some single containers (being generally the steel cylinder of operating pressure) to store high-pressure inert gas greater than 15Mpa; and container placed form fire extinguishing system in the protection zone, the inert gas that discharges in the container when breaking out of fire is put out a fire.The major defect of this method is, the container of stored-gas required high, need be provided with and takes up room greatly between independent storage bottle, cost an arm and a leg, and the gas capacity that stores is very limited.If fire is fierce, might after having discharged, gas still not reach the purpose of fire extinguishing.
Summary of the invention
In factories such as metallurgy, chemical industry, be extensive use of air-separating plant and extract industrial nitrogen as processing medium.The key technical indexes of this processing medium is: N2 〉=98.5%, O2≤1.5%.After above-mentioned processing medium is forced into 0.6～3.0MPa, is stored in the process pipe and is transported to each relevant range, form a huge nitrogen pipe network.
The present invention utilizes above-mentioned industrial nitrogen as extinguishing chemical; the nitrogen pipeline of setting up in the existing nitrogen pipe network of factory that For Use Only in Case of Fire; insert the protection zone by a cover controlling organization again; when breaking out of fire; nitrogen is sprayed to protection zone or object of protection, and nitrogen gas pressure is 0.8～3.0Mpa preferably.The nitrogen of certain pressure arranges or diluent air, object of protection oxygen concentration is on every side reduced, to reach the purpose of fire extinguishing rapidly.Can adopt by making nitrogen flood whole places at fire place, perhaps only flood the regional area of breaking out of fire or the mode of equipment and put out a fire.
Adopt such method fire extinguishing, a cost of investment only is 10% of traditional extinguishing device, and the use cost of extinguishing chemical is few especially to 5%, and because gas source almost is unlimited concerning fire extinguishing, increases the success rate and the reliability of fire extinguishing greatly.
Claims (3)
1. extinguishing method; it is characterized in that the technology nitrogen that the industrial production of utilizing the existing air-separating plant of factory to extract is used is transported to the flame failure protection zone by pipeline; when breaking out of fire, nitrogen is sprayed, put out a fire with total flooding or local mode of flooding by controlling organization.
2. extinguishing method as claimed in claim 1 is characterized in that, the pipeline pressure store is 0.6～3.0Mpa.
3. extinguishing method as claimed in claim 1 or 2 is characterized in that, the nitrogen that is stored in the process pipe with the industrial production use takes total flooding or local mode of flooding to put out a fire.
