| titleOfInvention | Production system for co-production of diphenyl sulfone and magnesium sulfate from benzene sulfonyl chloride |
| abstract | A production system for co-producing diphenylsulfone and magnesium sulfate by benzenesulfonyl chloride comprises a sulfonation kettle, a hydrolysis kettle, a water washing kettle and a distillation kettle which are sequentially connected in series through pipelines; the production system also comprises a magnesium sulfate production unit which comprises a neutralization reactor, a calcining furnace, a dissolving kettle, a filter press, a crystallizer and a dryer which are sequentially connected in series through pipelines; the production system also comprises a high-temperature high-pressure cyclone separator and a combustor; the invention converts the by-product sulfuric acid with low concentration in the traditional production mode into the sulfuric acid with the concentration of 60-65%, thereby reducing the water consumption of hydrolysis reaction, and enabling the layered sulfuric acid to be concentrated for the production of magnesium sulfate products; in addition, the waste heat generated by the neutralization reactor and the calcining furnace is used as a kettle body of the distillation kettle for heating, so that the energy is utilized to the maximum extent; the hot air generated by the neutralization reactor and the calcining furnace is supplied to the distillation kettle after passing through the cyclone separator, so that the inner layer of the jacket of the distillation kettle can be prevented from being blocked, and the organic matters in the sulfuric acid can be further removed. |
