Abstract

The invention relates to the technical field of organic-solvent recovery and particularly discloses an energy-saving rectifying system for recovering an organic solvent. The energy-saving rectifying system comprises a low-pressure tower, a medium-pressure tower and a high-pressure tower, wherein the high-pressure tower comprises a stripping section and a rectifying section; tower-top steam of thelow-pressure tower exchanges heat with tower-bottom liquid of the stripping section by a first condenser; the tower-bottom liquid of the low-pressure tower exchanges heat with tower-top steam of the rectifying section by a reboiler; tower-bottom liquid of the medium-pressure tower exchanges heat with tower-top steam of the medium-pressure tower by a second condenser, a second throttling valve anda second heat pump; the stripping section and the rectifying section of the high-pressure tower realize heat exchange in the high-pressure tower by a first heat pump and a first throttling valve. Theenergy-saving rectifying system for recovering the organic solvent disclosed by the invention has the advantages of low energy consumption, good energy-saving effect and low operation cost.

Description

technical field [0001] The invention relates to the technical field of organic solvent recovery, in particular to an energy-saving rectification system for recovering organic solvents. Background technique [0002] Organic solvent is a kind of solvent with organic matter as the medium. It can directly or indirectly disperse polymer compounds such as resins, pigments or dyes, and does not react with them. It can be volatilized after molding, so it is widely used in industry. With the rapid development of my country's industrial and agricultural production, the use of organic solvents is also increasing. The daily use of organic solvents in some large factories is 3 to 4 tons; that of medium factories is 1 to 2 tons; and that of small factories is about several hundred kilograms. Different types of factories that use organic solvents, such as container factories, copper clad laminate factories, plastic printing factories, furniture factories, chemical fiber factories, etc., a...
