Horizontal type biaxial distillation apparatus suitable for continuous separation of viscous material series

Abstract

The invention discloses a horizontal type biaxial distillation apparatus suitable for continuous separation of viscous material series. The horizontal type biaxial distillation apparatus comprises a closed container which is enclosed by a W-shaped barrel, an upper cover plate, a left end cover and a right end cover, as well as a rotor system which is composed of two left spindle heads, a plurality of fanshaped hollow heating plates, two hollow spindles, two right spindle heads and a set of transmission mechanism. Heating jackets are welded at the middle part and the lower part of the W-shaped barrel, an angle steel fixed frame is welded along an axial direction at the middle part of the inner side of the upper cover plate of an autoclave body, and scrapers of which the number is the same with that of the fanshaped hollow heating plate are equidistantly and uniformly arranged on the angle steel fixed frame. The horizontal type biaxial distillation apparatus can complete the separation of components with low boiling point in the viscous material series continuously and efficiently, and effectively overcome disadvantages that the material is adhesive to the wall of a traditional separation apparatus and discontinuous running of the traditional separation apparatus; the horizontal type biaxial distillation apparatus adopts an integrated structural design model, is compact in structure, has wide adaptability, has strong self-cleaning ability and little heat loss and high energy utilization ratio.

Description

technical field [0001] The invention relates to a horizontal double-shaft distillation device, in particular to a horizontal double-shaft distillation device suitable for continuous separation of viscous substances. Background technique [0002] In the process industries represented by chemical industry, petrochemical industry, light industry, food and pharmaceutical, the separation of mixture is the most common unit operation. The selection of the separation method mainly depends on the characteristics of the species to be separated. Generally, systems with a large difference in particle size can be separated by filtration, liquid phases with a large difference in boiling point can be separated by rectification, and those with a large difference in solubility can be separated by extraction. [0003] A viscous system is a mixed solution with high viscosity and high concentration, which is more common in the process industry. For example, in the typical phosphorus chemical ...

Problems solved by technology

However, once the mixer is improperly selected for this device, the viscous material will easily stick to the wall and accumulate thicker, which will directly increase the thermal resistance, resulting in a significant drop in heat transfer efficiency.

In addition, when the stirring type distillation separation device is used in a viscous system, the material is easy to agglomerate in addition to sticking to the wall and rotates synchronously with the stirring shaft, resulting in the material in the agglomerate being covered by the dry material on the surface and cannot be evaporated.
