Description

Technical Field

[0001] The utility model relates to the technical field of gas purification, in particular to a gas purification device for solvent extraction. Background Art

[0002] Solvent extraction, also known as liquid-liquid extraction or extraction, is a unit operation that uses the different solubility of components in the system in the solvent to separate the mixture; specifically, the solvent extraction method is to mix the organic phase and the aqueous phase with each other, so that the target substance in the aqueous phase enters the organic phase, and then the two phases are separated by relying on the difference in mass density of the two phases. In this process, a selected solvent that is incompatible with the liquid of the extracted mixture is usually used, and its solubility difference in different compounds is used for separation: In some extraction processes, if proper protective measures are not taken, harmful gases and vapors may be generated. For example, in the process of extracting nanocellulose with a metal salt solution, no harmful gas emissions will be generated if the reaction solution is not heated. However, in other cases, such as organic synthesis, harmful gases such as hydrogen cyanide may be generated if care is not taken, which need to be purified;
