PURPOSE:To efficiently produce gas contg. much oxygen content by providing such a gradient of magnetic force that the magnetic field of the center part of a vortex tube is made intensive for the radius direction. CONSTITUTION:An air chamber 2 is provided to a vortex tube 1 and air is introduced in the tangential direction through a nozzle 3 and a magnet coil 5 is wound around a flow rate control valve 4 in a cool air side of the flow rate control valves 4 for cool air and hot air and a gradient of magnetic force is formed so that the magnetic field of the center part of the tube 1 is made intensive for the radius direction. As a result, the concn. of oxygen in the cold air side can be raised. |
