METHOD AND DEVICE FOR MIXING OXYGEN WITH HYDROGEN-CONTAINING MIXTURES Russian patent published in 1995 - IPC

FIELD: diver's breathing systems. SUBSTANCE: oxygen under excessive pressure and finely divided hydrogen-containing gas mixture are fed to preliminary mixing chamber partially filled with water; then oxygen- and hydrogen-containing gas mixture is passed through layer of water and through gas bubble dividing device and is directed to outlet chamber of mixer. Gas mixing device is made in form of mixer having housing which is divided into preliminary mixing chamber, final mixing chamber and surge chamber with outlet pipe line by means of perforated partitions mounted perpendicularly to its longitudinal axis. Final mixing chamber is filled with water and is provided with device for finely dividing gas bubbles. preliminary mixing chamber is brought in communication with oxygen supply unit by means of diaphragm and is partially filled with water; pipe line for feeding the hydrogen-containing gas mixture mounted in the chamber is provided with divider secured at its end and submerged in water. Oxygen supply unit is made in form of throttle valve with hydrophobic plates inside it, hydrophobic catalyst and check valve connected in succession. EFFECT: enhanced efficiency. 5 cl, 1 dwg
