PURPOSE:To rapidly and uniformly mix an extremely small amount of a liquid with a large amount of liquid flowing through a pipeline without applying energy from the outside, by utilizing stirring and mixing action generated when the mechanical energy of the liquid in the pipeline is lost. CONSTITUTION:A pipeline 3 is provided in a pipeline 1 to divide said pipeline 1 into a flowline having an opening directed to the upstream of the pipeline through which the small part of a large amount of a liquid and a flowline through which the greater part of said liquid is flowed. In a pre-mixing part comprising said pipeline 3, an extremely small amount of a liquid is mixed into the flowline, through which the aforementioned small part is flowed, and both liquids are mixed by stirring action based on the friction in both liquids and the friction between the liquids and a solid surface. Next, in a mixing part, a flow reducing part 6 is adequately provided to the stream occupying the greater part of a large amount of the aforementioned liquid to generate an accelerated stream and the liquids mixed in the aforementioned pre-mixing part 3 are flowed into and mixed with the liquid in said pressure reduced part. By this method, an extremely small amount of the liquid can be rapidly and uniformly mixed with a large amount of the liquid flowing through the pipeline without applying energy from the outside. |
