Solid-liquid separation and binary component organic solvent purification combined complete equipment

Abstract

The invention discloses solid-liquid separation and binary component organic solvent purification combined complete equipment. The solid-liquid separation and binary component organic solvent purification combined complete equipment is characterized by comprising a binary component organic solvent purification device and a solid-liquid separation device, the solid-liquid separation device comprises an evaporator, a first feeding pump and a gas-liquid separator, the binary component organic solvent purification device comprises a supergravity rotating bed, a second feeding pump and a condenser, and a steam inlet pipe of the supergravity rotating bed is connected with a gas phase outlet of the gas-liquid separator. Two different technologies are combined into a whole, concentration and rectification of two substances can be achieved at the same time, when the solid-liquid separation device works, steam generated by distillation and concentration can enter a supergravity rotating bed of the two-component organic solvent purification device to be in contact with a two-component organic solvent for heat and mass transfer, and the two-component organic solvent is separated from the solid-liquid separation device. Steam latent heat generated in the concentration process of the solid-liquid separation device is fully utilized, and the device has the remarkable characteristics of high energy conservation, high efficiency, high efficiency, low carbon, environmental protection, residual purified tail liquid and the like.

Description

technical field [0001] The invention relates to the technical field of concentrated distillation, in particular to a combined complete set of equipment for solid-liquid separation and binary component organic solvent purification. Background technique [0002] With the continuous improvement of environmental protection requirements, reducing energy consumption and improving product economic benefits have become the goals pursued by all walks of life. Most of the organic solvents formed in the production process of small and medium-sized pesticides, medicines and fine chemicals can be recycled and reused to achieve the purpose of reducing costs, reducing emissions and avoiding pollution. [0003] At present, rectification towers or supergravity rotating beds are usually used to realize the rectification of organic solutions, and evaporators are used to realize the evaporation and concentration of materials, and a set of equipment can usually only realize the rectification or ...
