Distillation equipment capable of controlling temperature of condenser pipe and viscosity of fraction in real time and control method of distillation equipment

Abstract

The invention discloses distillation equipment for controlling the temperature of a condenser pipe and the viscosity of fractions in real time and a control method of the distillation equipment. The equipment comprises a heating device, a distillation device and a condensing device which are connected with one another. According to the present invention, the condensation pipe monitoring jacket is arranged on the outer wall of the condensation pipe, the collector monitoring jacket is arranged on the outer wall of the collector, and the circulating water bath control unit is used to perform online viscosity monitoring on the distillate component so as to make the distillate component have flowability in the set range, and if the online viscosity monitoring result shows that the viscosity is not in the normal distillate range, the condensing device is heated through the circulating water bath control unit, and the viscosity of distilled components is reduced when the temperature rises because the temperature and the viscosity have an inverse relation, so the equipment has the advantages of reasonable structure, simplicity in operation, real-time automatic control, practicability and high efficiency.

Description

technical field [0001] The invention relates to the technical field of distillation equipment, in particular to a distillation equipment and a control method thereof for real-time control of the temperature of a condensing tube and the viscosity of a distillate. Background technique [0002] Distillation is a thermodynamic separation process, which is a combination of two unit operations of evaporation and condensation. 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 system components. This ensures that no new impurities are introduced. [0003] The distillation equipment in the prior art, such as the boiling point distillation device is a set of kettle-type atmospheric and vacuum distillation equipment, which has a strong fractionation ability. After passing through the boiling point distillation device, crude oil and coal tar can be cut into different narrow ...
