PRODUCTION METHOD FOR AIR REGENERATION Russian patent published in 2008 - IPC A62D9/00

Abstract RU 2325205 C2

FIELD: fire-fighting components; production method of regenerating products.

SUBSTANCE: method includes interaction of hydrogen peroxide solution with potassium hydroxide at mole ratio l.5÷2.0. Before dehydration calcium hydroxide is introduced into the produced solution at mole ratio 1.0÷3.0 of hydrogen peroxide/calcium hydroxide. Temperature of reaction area should not exceed 50°C. Further dehydration is done by spraying the produced solution in drying agent flow.

EFFECT: production of regenerating product is ensuring longer time for protection of respiratory system and smaller value of aerodynamic resistance and temperature of gas-air mixture supplied to user.
