Abstract: Disclosed is a gas-liquid contact system. The system includes a vessel arranged approximately perpendicular to the ground in a longitudinal direction, a static fluid mixer in the vessel having a passage tube and a spiral blade provided in the passage tube, a gas supplier supplying gas having foreign substances to the static fluid mixer from a lower end of the vessel, a gas discharger discharging the gas passed through the static fluid mixer from an upper end of the vessel, a first liquid supplier supplying liquid to the static fluid mixer, and a liquid discharger discharging the liquid supplied from the first liquid supplier outside of the vessel. In the system, the gas supplier includes a gas generator generating gas, a pipe connecting the gas generator with the vessel, a blowing device provided in the pipe, and a second liquid supplier supplying liquid to the pipe between the gas generator and the blowing device.

Abstract: A mixing element, which is produced at low cost, has high mixture agitation effectiveness, and is easily made large, and a static fluid mixer using the mixing element are provided. Further, a gas-liquid treatment apparatus with high treatment ability is provided. A mixing element 1 includes: a cylindrical passage tube 2 trough which fluid flows; a plurality of spiral rightward rotation type first blades 3 formed of a perforated object, which are provided in the passage tube 2; a first inner cylindrical tube 5 shaped like a cylinder and disposed inside the blades 3; a plurality of spiral rightward rotation type blades 6 provided in the inner cylindrical tube 5; and an opening 9 formed in the axial center portion of the blades 6. A static fluid mixer is formed by using at least one mixing, element 1 mentioned above.

Abstract: Disclosed is a fluid mixer that includes a plurality of fluid mixing units each having openings and a mixing portion arranged in a packed column. In the fluid mixer, the plurality of fluid mixing units are irregularly arranged in axial directions different from each other.
