The present application relates to
wastewater distillation technical field, especially to a kind of chemical
raw material intermediate
wastewater distillation equipment and
distillation method thereof.It includes primary distillation unit and condensing unit, the bottom of the primary distillation unit is connected with secondary distillation unit, the primary distillation unit includes distillation ball of spherical structure, first rotating rod is rotatably connected in the distillation ball, the periphery of the first rotating rod is
annular array distribution with several groups of first scraping mechanism;The secondary distillation unit includes distillation kettle with hemispherical structure at bottom.The present application carries out secondary distillation in the form of hierarchical intensity, not only save
energy consumption, but also improve distillation effect and harmful substance separation effect.At the same time, distillation ball and distillation kettle are respectively set as spherical and hemispherical, reduce bottom area, reduce
precipitation probability, and use first scraping mechanism and second scraping mechanism to respectively stir and scrape wall of the inner wall of both, also reduce the residue of waste residue.
