The invention discloses a distillation equipment for chemical production, comprising a cavity, a preheating pipe, a liquid outlet layer, a distillation box and a liquid inlet layer, the cavity is arranged inside the top of the equipment shell, and the liquid inlet The top of the layer is provided with an array of air outlet pipes, the upper end of the air outlet pipe is connected to the cavity, and a liquid feeding pipe is provided on the left and right sides of the liquid inlet chamber layer. The inner layer pipe is arranged on the preheating pipe, and the inner layer pipe is sleeved on the outside. There is an outer tube, a heating wire is arranged between the inner tube and the outer tube, a rotating shaft is arranged inside the inner tube, an array of aeration heads is arranged at the bottom of the outlet chamber, and an array is arranged inside the distillation box. The right side of the liquid collecting chamber is provided with a third connecting pipe distributed in an array, the right side of the third connecting pipe is connected with a split distillation tube, and a heating plate is arranged at the lower end of the split distillation tube. The invention is used in the distillation equipment of chemical industry, increases the heating area, realizes high-efficiency distillation, shortens the distillation time, has high purity, and can avoid liquefaction in the gas phase mass transfer process by preheating.
