[Technical Field] The present invention relates to a technology that is effective when applied to improve the performance of fire extinguishers used in low-temperature environments. [Background technology] A fire extinguisher usually has a small high-pressure gas container attached to the inside of the main body container, and this high-pressure gas container is filled with high-pressure gas to squirt the extinguishing agent to the outside. . Carbon dioxide gas has conventionally been used as the high-pressure gas. In addition to being cheap and harmless, carbon dioxide gas has a high critical temperature (31.0℃).
Because it has the property of easily liquefying at relatively low pressure at normal temperatures, it is extremely suitable as a high-pressure gas for fire extinguishers, as it can be filled in a large amount into a small high-pressure gas container. It has a characteristic. However, carbon dioxide gas has problems as a gas to be filled into a high-pressure gas container of a low-temperature fire extinguisher used in a low-temperature environment such as a cold region or a frozen warehouse. In other words, when liquefied carbon dioxide filled in a high-pressure gas container is rapidly vaporized at low temperatures, the remaining liquefied carbon dioxide in the high-pressure gas container cools and solidifies due to the rapid loss of latent heat of vaporization, forming solid carbon dioxide (dry ice). ), it becomes impossible to secure a sufficient amount of carbon dioxide gas to be released after that, and the fire extinguishing agent is no longer sufficiently ejected. [Purpose of the invention] The purpose of the invention is to provide a fire extinguisher suitable for use in low-temperature environments. The above and other objects of the present invention will become apparent from the specification and accompanying drawings. [Summary of the invention] The low-temperature fire extinguisher of this invention contains a mixed gas consisting of carbon dioxide gas and 15 mol% or more of nitrogen in a small high-pressure gas container that supplies high-pressure gas to blow out the extinguishing agent to the outside. By filling the container with dry ice and preventing dry ice from forming inside the high-pressure gas container when used in low-temperature environments, all of the mixed gas can be effectively used as an energy source for blowing out extinguishing agent. be. Generally, a gas will not liquefy at a temperature above its critical temperature no matter how high the pressure is. That is, the gas filled in the high-pressure gas container of a fire extinguisher will not liquefy at a temperature above its critical temperature, no matter how much the pressure inside the container is increased. As shown in Table 1 below, a mixed gas of carbon dioxide and nitrogen has a property that its critical temperature decreases as the molar fraction of nitrogen in the mixed gas increases.

[Table] Therefore, in the fire extinguisher of the present invention, in which the high-pressure gas container is filled with a carbon dioxide gas-nitrogen mixed gas whose critical temperature is lower than that of carbon dioxide gas, liquefied carbon dioxide gas is generated in the high-pressure gas container even at low temperatures. Never. In other words, when the low-temperature fire extinguisher of the present invention is used in a low-temperature environment, the carbon dioxide gas in the container will not cool and solidify into dry ice, so all of the mixed gas in the high-pressure gas container can be used to blow out the extinguishing agent. It can be effectively used as an energy source, and it can spray out a sufficient amount of extinguishing agent. Normally, a temperature of about 20°C is called normal temperature, so low temperature means a temperature lower than this. Since the low-temperature fire extinguisher of this invention is intended for use in environments with temperatures lower than 20℃,
The proportion of nitrogen in the mixed gas filled in the high-pressure gas container must be 15 mol% or more. This is because a mixed gas with a nitrogen content of less than 15 mol% has a critical temperature higher than 20°C (see Table 1), so the carbon dioxide in the high-pressure gas container liquefies in a low-temperature environment, and when used This is because this liquefied carbon dioxide solidifies and produces dry ice. On the other hand, the upper limit of the proportion of nitrogen in the mixed gas filled in the high-pressure gas container cannot be univocally defined. In other words, as the proportion of nitrogen in the mixed gas increases, the critical temperature of the mixed gas also decreases.
Although it has the advantage of being able to be used in even lower temperature environments, mixed gas of carbon dioxide and nitrogen
As shown in Table 2 below, as the mole fraction of nitrogen in the mixed gas increases, the capacity that can be filled in a container with constant pressure and volume decreases, so in order to spray out a sufficient amount of extinguishing agent, However, there is also the disadvantage that the high-pressure gas container must be made larger.

The figure is a schematic cross-sectional view of the low temperature fire extinguisher of this example. A powder extinguishing agent (not shown) is contained in a main body container 1 of this low-temperature fire extinguisher, and the main body container 1 is sealed with a cap 2 at its upper end. This cap 2 is provided with a holder 3, and a small-sized high-pressure gas container 4 is screwed into the holder 3 and attached to the holder 3 at its opening. A handle 5 and a lever 6 are attached to the upper part of the cap 2, and the lever 6 is rotatably connected to the tip of the handle 5. A safety plug 7 is provided between the handle 5 and the lever 6 to prevent the lever 6 from rotating when not in use. Further, a cutter 8 is attached to the center of the holder 3 in a slidable manner and interlocked with the lever 6. A gas introduction pipe 9 communicating with the inside of the holder 3 and a siphon pipe 11 communicating with a hose 10 provided on the side of the cap 2 are attached to the cap 2, respectively. The hose 10 has a nozzle 12 at its tip, and a horn 1 at its tip.
3 are attached respectively, and this horn 1
The opening 3 is sealed by a horn cap 14. To use the low-temperature fire extinguisher of this embodiment, first remove the safety hydrant 7 and horn cap 14, then grasp the handle 5 and lever 6 while keeping the opening of the horn 13 facing the object to be extinguished. Lever 6
move downward. Then, the cutter 8 slides downward and the sealing plate 4a of the high pressure gas container 4 is broken.
The mixed gas 15 filled in the high-pressure gas container 4 is vigorously jetted into the main container 1 from the tip of the gas introduction pipe 9, so that the extinguishing agent is sprayed into the siphon pipe 1.
1 to the hose 10, and then the horn 1
The mixed gas is ejected to the outside from the opening 3. The low-temperature fire extinguisher of this embodiment is characterized in that the high-pressure gas container 4 is filled with a mixed gas 15 consisting of carbon dioxide and 15 mol % or more of nitrogen at high pressure. The mixed gas 15 having the above composition has a critical temperature of room temperature (20
C) and will not liquefy under any pressure above its critical temperature. Therefore,
The low-temperature fire extinguisher of this embodiment is designed to dry when the mixed gas 15 in the high-pressure gas container 4 is spouted into the main container 1 in a low-temperature environment due to loss of latent heat of vaporization, as in the case of using liquefied carbon dioxide gas. Since no ice is generated, the entire amount of the mixed gas 15 can be vigorously jetted into the main body container 1, and the function of the fire extinguisher can be fully exhibited. In addition, as another method in which the carbon dioxide gas is not solidified in the high-pressure gas container 4 and the entire amount is spouted forcefully into the main body container 1, for example, the high-pressure gas container 4 is filled with liquefied carbon dioxide gas, and the liquid level is In the space between the upper part and the inner wall of the container 4, there is a liquid-resistant substance such as nitrogen,
It is conceivable to allow a hardly soluble gas to coexist and install the high-pressure gas container 4 in the fire extinguisher with the opening facing downward from the container body 1. In this way, the liquefied carbon dioxide in the high-pressure gas container 4 flows into the main container 1 in a liquid state and evaporates there, so the latent heat of evaporation from the surroundings is greater than when it evaporates in the high-pressure gas container 4. Therefore, dry ice is not generated in the high-pressure gas container 4 or in the gas introduction pipe 9. However, even in this method, if liquefied carbon dioxide exceeds a certain amount and flows into the main container 1, dry ice will be generated in the main container 1, and as a result, the high pressure gas container 4 will be filled with dry ice. The drawback is that the gas cannot be used effectively, and the fire extinguisher does not function adequately in low-temperature environments. On the other hand, in the low-temperature fire extinguisher of this embodiment, dry ice is not generated in either the high-pressure gas container 4 or the main container 1 during use, so the high-pressure gas container 4 is filled with dry ice. The entire amount of the mixed gas 15 can be effectively used as an energy source for blowing out the extinguishing agent. Furthermore, the low-temperature fire extinguisher of this embodiment allows a larger amount of gas to be filled into the high-pressure gas container 4 than when a gas commonly used as a high-pressure gas, such as nitrogen, is used alone. However, even in this case, if the proportion of nitrogen in the mixed gas 15 increases, the amount of gas that can be filled into the high-pressure gas container 4 will decrease.
It is necessary to optimize the balance between the critical temperature of 5 and the size of the fire extinguisher. The invention made by the inventor has been explained above based on the examples, but the low temperature fire extinguisher according to the invention is not limited to the configuration described in the examples, and the gist of the invention has been changed. There is no problem in making various design changes to the extent that no changes are made. For example, the shapes of the container body and the high-pressure gas container are not limited to the shapes shown in the above embodiments, but may be of any shape as long as they have the same function. Further, in the low temperature fire extinguisher of the present invention, the high pressure gas container is not filled with liquid, so when the high pressure gas container is installed in the main container, the opening may be oriented in any direction. The low-temperature fire extinguisher of this invention can be used at room temperature (20℃).
Needless to say, even when used in a high-temperature environment, it can fully exhibit its function as a fire extinguisher. [Effects of the invention] The low-temperature fire extinguisher of the present invention has a small high-pressure gas container that supplies high-pressure gas for ejecting extinguishing agent to the outside, and is filled with a mixed gas consisting of carbon dioxide gas and 15 mol% or more of nitrogen. Even when used in a low-temperature environment, all of the gas in the high-pressure gas container can be effectively used as an energy source for ejecting extinguishing agent, so it can exhibit excellent fire extinguishing performance.
