Description

Technical Field

[0001] This utility model relates to the field of VOCs solvent recovery technology, and in particular to an integrated cold source VOCs solvent recovery device. Background Technology

[0002] VOCs refer to a class of organic compounds that are easily volatile at room temperature. They are widely found in industries such as industrial production, coatings, printing, chemicals, pharmaceuticals, and electronics. VOCs solvents are liquids used to dissolve, dilute, or carry other substances. They are usually highly volatile, flammable, and have a certain degree of toxicity. Therefore, VOCs solvents need to be recycled after use.

[0003] Currently, when recovering high-temperature VOCs solvent vapor, only simple cooling can be performed, which reduces the condensation effect of the VOCs solvent and cannot be adsorbed and recovered, thus reducing the recovery effect of source VOCs solvent. Therefore, we propose an integrated cold source VOCs solvent recovery device to solve the above problems. Utility Model Content
