| titleOfInvention | Method for continuously preparing water-soluble azo dye by coupling atomizer with pipeline |
| abstract | The invention provides a method for continuously preparing a water-soluble azo dye by coupling an atomizer with a pipeline. According to the method, the atomizer and the pipeline with an interception tower plate are coupled, atomized and mixed reaction liquid flow flows through the pipeline with the interception tower plate, and mixing and reacting are further enhanced by mixing with turbulent flow on the tower plate, so that instant separation of reaction heat generated in an atomizing contact reaction from a reactant is realized, and normal-temperature rapid continuous production of the water-soluble azo dye is realized. Fog drops which are atomized by using the atomizer have the advantages of small particle diameter and large specific surface area, so that a diazo salt and a coupling component are sprayed respectively, move face to face and can be fully contacted, and mixing and reacting speeds are increased. The preparation method provided by the invention is simple; and compared with preparation of a dye of the same kind with an intermittent reaction kettle, the method has the advantages that in the preparation process of the water-soluble azo dye, a cold source is not required to be added additionally for cooling, remarkable energy-saving and consumption-reducing properties are realized, and energy-saving, efficient and high-quality production of the water-soluble azo dye is realized. |
