Description

Liquid storage method and equipment for gas fire extinguishing agent
Technical Field
The invention relates to the technical field of liquid gas storage, in particular to a liquid storage method of a gas fire extinguishing agent and liquid storage equipment of the gas fire extinguishing agent.
Background
At present, water is generally used for fire fighting or a fire extinguisher is used. Fire fighting with water is economical, but water fighting suffers from the following drawbacks: firstly, fire cannot be extinguished with water, and secondly grease fires cannot be extinguished with water.
The fire extinguisher is divided into a foam fire extinguisher, a dry powder fire extinguisher and a carbon dioxide fire extinguisher, and the fire extinguisher has the following characteristics:
foam fire extinguisher: the foam fire extinguisher is internally provided with two containers which are respectively used for containing two liquids, namely aluminum sulfate solution and sodium bicarbonate solution, the two solutions are not contacted with each other and do not have any chemical reaction. When the foam fire extinguisher is needed, the fire extinguisher is inverted, and the two solutions are mixed together, so that a large amount of carbon dioxide gas can be generated.
Dry powder fire extinguisher: the dry powder fire extinguisher is filled with a dry powder fire extinguishing agent. The dry powder fire extinguishing agent is dry and easy-to-flow fine powder for extinguishing fire, and consists of inorganic salt with fire extinguishing effect and small amount of additive, which are dried, crushed and mixed to form fine solid powder. The compressed carbon dioxide is used to blow out dry powder (mainly containing sodium bicarbonate) to extinguish the fire.
Carbon dioxide fire extinguisher: carbon dioxide has a relatively high density, about 1.5 times that of air. At atmospheric pressure, the liquid carbon dioxide is immediately vaporized, and typically 1kg of liquid carbon dioxide can produce about 0.5 cubic meter of gas. Therefore, when fire is extinguished, the carbon dioxide gas can be exhausted to surround the surface of a burning object or be distributed in a relatively closed space, the oxygen concentration around the combustible or in a protective space is reduced, and the fire is extinguished by a suffocation effect. In addition, when the carbon dioxide is sprayed out of the storage container, the liquid is quickly vaporized into gas, and partial heat is absorbed from the periphery to play a cooling role.
When a foam fire extinguisher, a dry powder fire extinguisher and a carbon dioxide fire extinguisher are used, the carbon dioxide can play a combustion-supporting role for some alkali metals on fire, so that the carbon dioxide can not be used.
Therefore, the IG100 and the IG55 are adopted to extinguish fire, and are safe and effective. The IG100 fire extinguishing agent is nitrogen (pure nitrogen), the code is IG100 in the American fire protection Association standard NFPA2001 and the Chinese national standard, the nitrogen is a component in the air, is colorless, odorless, non-corrosive and non-conductive, has no residue after being sprayed, is an environment-friendly gas, does not change the chemical property of the air, has the GWP (greenhouse effect potential value) and ODS (ozone depletion potential value) of 0, in other words, does not damage the ozone layer and does not cause the greenhouse effect, does not react with other substances or mixtures, still maintains the chemical property after being used, and does not cause secondary pollution to other substances. The IG55 fire extinguishing agent is a mixed gas of nitrogen and argon, and the code is IG55 in the American fire protection Association standard NFPA2001 and the Chinese national standard, the nitrogen and the argon are components in the air, are colorless, tasteless, non-corrosive and non-conductive, have no residue after being sprayed, are not only environment-friendly gases, but also do not change the chemical properties of the air, and the GWP (greenhouse potential value) and the ODS (ozone depletion potential value) of the nitrogen and the argon have 0 value, in other words, the nitrogen and the argon do not damage the ozone layer and cause the greenhouse effect, do not react with other substances or mixtures, still keep the chemical properties of the nitrogen and the nitrogen after being used, and do not cause secondary pollution to other substances. The IG100, IG55 fire extinguishing system, adopt "submerge" the immersion fire extinguishing principle completely, make the oxygen concentration in the protective area reduce to below 15%, make the fire go out, the fire extinguishing principle of the nitrogen is the physical fire extinguishing principle, while putting out a fire, spray into the airtight protective area, make the indoor oxygen concentration reduce to above 15%, thus can't support the combustion, the nitrogen does not take place the chemical reaction with any substance in the protective area, return to the atmosphere after spraying and putting, there is no any residue; however, the temperature in the storage tank is easily influenced by external factors, so that the temperature in the storage tank is increased, the stored liquid IG100 and IG55 are easily vaporized, the content of the liquid IG100 and IG55 in the storage tank is reduced, and how to store the IG100 and IG55 is a great technical problem.
