Abstract: Disclosed is a method for continuously preparing a water-soluble azo dye by coupling a nebulizer with a pipeline. According to the method, the nebulizer is coupled with a pipeline with an interception tower plate, atomized and mixed reaction liquid flow flows through the pipeline with the interception tower plate, and mixing and reacting are further enhanced through turbulent mixing on the tower plate, so that instant separation of reaction heat generated in an atomizing contact reaction from a reactant is achieved, and normal-temperature rapid continuous production of the water-soluble azo dye is achieved. Fog drops which are atomized by using the nebulizer have small particle diameter and large specific surface area, so that a diazo salt and a coupling component are sprayed separately, move face to face and can be fully contacted, and mixing and reacting speeds are increased.
