Distillation equipment for chemical production

Abstract

The invention discloses distillation equipment for chemical production. The distillation equipment comprises a cavity, pre-heating pipes, a liquid outlet cavity layer, a distillation box and a liquidinlet cavity layer, wherein the cavity is arranged at the inner side of the top of an equipment shell; air outlet pipes which are distributed in an array are arranged at the top of the liquid inlet cavity layer; the upper ends of the air outlet pipes are communicated with the cavity; a liquid inlet pipe is arranged at each of the left and right sides of the liquid inlet cavity layer; each pre-heating pipe is provided with an inner-layer pipe and an outer-layer pipe sleeves each inner-layer pipe; heating wires are arranged between the inner-layer pipes and the outer-layer pipes; each inner-layer pipe is internally provided with a rotary shaft; aeration heads which are distributed in the array are arranged at the bottom of the liquid outlet cavity layer; the distillation box is internally provided with a liquid collection cavity; third connection pipes which are distributed in the array are arranged at the right side of the liquid collection cavity; the right sides of the third connection pipes are connected with flow dividing distillation pipes; heating plates are arranged at the lower ends of the flow dividing distillation pipes. The distillation equipment for the chemical production, disclosed by the invention has the advantages that the heating area is increased, the efficient distillation is realized, the distillation time is shortened and the purity is high; liquefaction ina gas phase mass transferring process can be avoided through pre-heating.

Description

technical field [0001] The invention relates to a distillation device, in particular to a distillation device for chemical production. Background technique [0002] Distillation is a thermodynamic separation process. It utilizes the different boiling points of the components in the mixed liquid or liquid-solid system to evaporate the low-boiling components and then condense them to separate the entire components. There are two types of evaporation and condensation. A union of unit operations. Compared with other separation methods, such as extraction, filtration and crystallization, its advantage is that it does not need to use other solvents other than the system components, so as to ensure that no new impurities will be introduced. The relationship between human beings and chemical industry is very close, and it has spread to all aspects of life. In modern life, chemical products are inseparable almost anytime and anywhere. From material life such as clothing, food, hous...
