PURPOSE:To make it possible to perform uniform mixing, by a method wherein two or more of mixing pipe parts constituted so as to be provided in a connected state are enlarged in the widths thereof larger than the diameters of liquid feed pipes connected to said mixing pipe parts and the width enlarging directions thereof are made regularly different while wach cross-sectional area thereof is made almost the same to that of each liquid feed pipe. CONSTITUTION:A gradient mixer 1 is constituted of liquid feed pipes 2 and mixing pipe parts 3-7 formed on the way of said liquid feed pipes 2 and constituted so as to move a solvent 8 to be mixed. The mixing pipe parts 3, 5, 7 are pipes each having a flat cross-sectional shape and mixing pipe parts 4, 6 are provided so that the pipes same to the mixing pipe parts 3, 5, 7 are provided so as to cross the longitudinal directions of the flat cross-sectional area shapes at right angles. The solvent 8 is smoothly mixed without forming large reverse flow or stagnant flow because by the mixing pipe parts 3-7 because the cross- sectional area shapes are largely changed. |
