Therefore, some enterprises begin to improve the preparation process of the diazonaphthoquinone compound: by adopting the mixing and collocation of thionyl chloride and chlorosulfonic acid, the reaction is promoted to be carried out smoothly, so that the consumption of chlorosulfonic acid is reduced, and the production of waste liquid and waste gas is reduced. In the actual production process, sodium diazosulfonate, a solvent and organic alkali are added into a reaction kettle to be stirred and dispersed uniformly, and then thionyl chloride and chlorosulfonic acid are added into the reaction kettle to react; after the reaction is finished, adding ultrapure water to extract the diazonaphthoquinone compound by a centrifugal extractor; and finally, adding active carbon into the extracted material, stirring, and filtering the active carbon to obtain an organic layer. Then removing the solvent of the organic layer to slowly obtain a crystal; filtering the crystals, and cleaning the filter cake with benzene to obtain the finished product of the crystal particles.

The centrifugal impeller is mainly directly driven by a rotary drum driving shaft, and the rotary drum is high in rotating speed, so that the centrifugal impeller has a relatively strong effect on materials, and a relatively large vibration quantity can be generated by the centrifugal impeller in the working process; in the process of transmitting vibration quantity through a drum driving shaft, the high-speed rotation stability of the drum is easily influenced, so that the service life of equipment is shortened, and the separation precision of the drum to materials is reduced.
