PROBLEM TO BE SOLVED: To provide a method for mixing fluids, which can be applied to combustible or corrosive fluids, and an apparatus for mixing the fluids, the structure of which is simplified.SOLUTION: In a venturi type apparatus 1 for mixing the fluids, a venturi tube 5 is arranged on a main pipeline 3, and a liquid second fluid is supplied to a gaseous first fluid which is supplied from the upstream side of the venturi tube 5 at the throat part 9 of the venturi tube 5 or the upstream side thereof, and then both the fluids are mixed with each other. The venturi apparatus 1 for mixing the fluids includes: a branched tube 7 which is branched from the main pipeline 3, and in which the cross section of a flow passage has a small diameter part smaller than the diameter of the main pipeline 3, and the outlet side of which is connected to the throat part 9 of the venturi tube or the upstream side thereof; an inner tube 12 which is arranged in the small diameter part of the branched tube 7 or in the vicinity thereof along the axial direction of the branched tube 7, so that the small diameter part of the branched tube 7 or the vicinity thereof is formed into a double tube structure; a supply part for supplying the second fluid into the inner tube 12; and a flow rate control valve 15 which is arranged on the main pipeline 3 on the downstream side of the branched part of the branched tube 7 and is used for controlling the flow rate of the fluid flowing in the main pipeline 3. |
