Action

  The simple fire extinguisher according to the present invention is always placed in a place where it can be easily taken out, and in the event of a fire, hold the proximal end of the handle bar with one hand and put the container part into the tempura pan. The part of the superabsorbent resin exposed to the high temperature of the tempura oil surface is dissolved or decomposed to release the extinguisher aqueous solution of the cross-linked product, and the tempura is generated by the heat of vaporization (latent heat) when the water becomes water vapor. Takes heat from oil and extinguishes by cooling. It works to lower the temperature of tempura oil below the flash point. In addition, the highly water-absorbing resin foams, and the foamed resin covers the flame and the hot oil surface, shuts off the air and extinguishes the fire.

Inventive embodiment

  In the present invention, the container of the superabsorbent resin (water extinguisher solution absorbed) can be used in any shape such as spherical, cylindrical, prismatic, bag-like, plate-like, and airtight. You can use something with The container may be transparent, translucent or opaque.

  In order to extinguish the fire, the container is put into the fire, and the fire extinguisher aqueous solution absorbed in the superabsorbent resin contained in the container is discharged from the oil surface and the part exposed to the high temperature, and is vaporized. ) Take the heat of tempura oil, lower the temperature and extinguish the fire. The amount of the extinguishing agent aqueous solution absorbed by the superabsorbent resin used is preferably 100 ml or more per liter of tempura oil.

  FIG. 3 shows a highly water-absorbent resin (water extinguisher solution was absorbed).

  Therefore, if the container is airtight as the material or material of the container used, for example, if it is at a high temperature (350 ° C or higher) such as a tempura oil fire, the container will disappear or soften / melt due to the flame or oil temperature. Then, at least part of it is destroyed, and the superabsorbent resin (the fire extinguisher aqueous solution is absorbed) may be released. Accordingly, natural resin, paper, and cellulose-modified synthetic resin are preferable because they disappear with a flame. When a synthetic resin is used, its softening or melting temperature may be lower than the oil temperature at the time of fire. Polyethylene, polypropylene, nylon, polyethylene terephthalate, polyvinyl chloride, polystyrene and the like are used. These blends can also be used.

  The aqueous fire extinguisher solution is a fire extinguishing liquid obtained by diluting a fire extinguishing agent “FireAde2000” with water to a concentration of 0.1 to 10% by mass.

  FIG. 2 shows the water absorption mechanism of the highly water-absorbent resin (with the extinguishing agent aqueous solution absorbed).

  As a material for the handle bar, a metal such as aluminum or stainless steel, a synthetic resin such as polyethylene, polypropylene, nylon, polyethylene terephthalate, polyvinyl chloride, or polystyrene, or a composite synthetic resin material can be used.

  The material of the string-like body that suspends the container containing the fire extinguishing agent through the string-like body at the tip of the handle bar may be any material that disappears or softens, melts and breaks in a fire. Natural fibers and synthetic fibers are preferably used.

effect

  With this simple fire extinguisher, the container portion is completely extinguished within 15 seconds from the time when the container portion is put into the tempura pan during a tempura oil fire, and is not reignited. Being able to extinguish fire is a big advantage for those who are panicking with a tempura oil fire.

  An embodiment based on the present invention will be described with reference to FIG. In FIG. 1, a handle bar 4 (expandable or stick) and a container 2 containing a fire extinguisher at a tip 5 of the handle bar 4 via a string-like body 6 are placed in a tempura pan 8 where a fire has occurred. Is shown in a state of being inserted. In this example, a stainless steel one was used. The handle bar 4 here may be a rectangular tube-shaped telescopic or bar.

  The container 2 is a bag made of a synthetic resin. However, when the container 2 is put into a burning tempura pan 8 (injection of about 1 liter of tempura oil), it immediately disappears due to the flame and is contained. A superabsorbent resin (a fire extinguisher obtained by diluting a fire extinguishing agent “FireAde2000” with water to a concentration of 0.25 mass%) in which 450 g of the extinguisher aqueous solution was absorbed in 1.5 g of the superabsorbent resin was released from the container and tempura While falling into the tempura oil in the pan 8 (oil temperature about 350 ° C. to 370 ° C.), the superabsorbent resin is exposed to a high temperature, so that the absorbed fire extinguisher aqueous solution is released and becomes water vapor. The heat of vaporization (latent heat) takes the heat of tempura oil and extinguishes it. When the highly water-absorbent resin is exposed to high temperature, it foams, and the foamed resin covers the oil surface and extinguishes fire. The time from when the container 2 was put into the tempura pan during a fire to the extinction was within 10 seconds. And there was no reignition.

  Tempura oil is said to have an auto-ignition temperature of 300 ° C to 370 ° C, from old to new oxidized oil. In this example, the oil temperature during combustion was about 350 ° C.

An embodiment based on the present invention will be described with reference to FIG.
The container 2 is a bag made of a synthetic resin. However, when the container 2 is put into a burning tempura pan 8 (injection of about 1 liter of tempura oil), it immediately disappears due to the flame and is contained. A superabsorbent resin (a fire extinguisher obtained by diluting a fire extinguishing agent “FireAde2000” with water to a concentration of 0.25% by mass) in which 1 g of the superabsorbent resin absorbs 300 ml of a fire extinguisher aqueous solution is discharged from the container and the tempura pan 8 Falls into tempura oil (oil temperature of about 350 ° C. to 370 ° C.) and the superabsorbent resin is exposed to a high temperature, so that the absorbed water solution of the extinguisher is released and becomes water vapor. The heat of the tempura oil is taken away by (latent heat) and extinguishes. When the superabsorbent resin is exposed to a high temperature, it foams, and the foamed resin covers the oil surface to extinguish the fire. The time from when the container 2 was put into the tempura pan during a fire to the extinction was within 15 seconds. And never ignited again

  The effect of super water-absorbent resin (1 g of super water-absorbent resin absorbed 300 ml of fire extinguisher aqueous solution) is that the specific heat of tempura oil ≒ 0.5, specific gravity ≒ 0.9, the weight of tempura oil of 1000 ml is ≒ 900 g Heat amount of tempura oil 900 g (oil temperature 350 ° C.) = 0.5 × 900 g × 350 ° C. = 157,500 cal = 157.5 Kcal, 300 g of fire extinguisher aqueous solution is put into tempura oil with an oil temperature of 350 ° C. 300 g × 539 cal + α = 161,700 cal + α = 161.7 Kcal + α, As a result, the oil temperature of tempura oil drops and does not reignite.
