  The present invention belongs to a fire extinguishing apparatus for fire extinguishing, and particularly relates to a foam extinguisher storage and mixing radiation tube apparatus.

  Fire takes people's property and eventually lives. Therefore, in order to extinguish the fire quickly, for example, bazaar venues, movie theaters, government offices, schools, factories, business establishments, houses, etc. are equipped with hand-held fire extinguishers, among them hand-held foam fire extinguishers and powder fire extinguishers Is said to be particularly effective against early fires.

A conventional foam extinguisher is filled with a mixed aqueous solution in which a foam extinguisher and water are mixed, and is filled with 7 to 10 kg / cm ² of high-pressure air or nitrogen gas, and further above the extinguisher. A hand-held control valve is attached, and a hose and a nozzle are connected to the outlet of the hand-held control valve.

  However, since the mixed aqueous solution of fire extinguisher and water used in such a commercially available foam fire extinguisher is easily changed, it is necessary to replace it with a new mixed aqueous solution when the shelf life of 2 years has passed. There are also foam fire extinguishers where the mixed aqueous solution has only one year. Such a fire extinguisher is not only economical, but in some cases it may affect fire fighting operations. In addition, when the mixed aqueous solution is refilled, the waste liquid treatment and environmental sanitation are greatly affected.
