<P>PROBLEM TO BE SOLVED: To minimize reduction in effect of water treatment even if an ultraviolet lamp is spaced from liquid, in simultaneous purification treatment of liquid and gas by ultraviolet irradiation, by passing the liquid through a spiral tube. <P>SOLUTION: The ultraviolet lamp is disposed at the center of a cylindrical jacket 1, and a hollow tube 3 is spirally wound around the ultraviolet lamp 2 twice or more. Air is sent from one opening 1a side of the cylindrical jacket 1, and water 6 is sent into the tube 3 from one end thereof. The sent air is treated with ultraviolet ray emitted from the ultraviolet lamp 2, and treated air is obtained from the other opening 1b. At the same time, the water passed through the tube 3 is treated with the ultraviolet ray while flowing along the flow passage extended in length by being made spiral, and treated water is obtained from the other end. <P>COPYRIGHT: (C)2012,JPO&INPIT |
