Description

Technical Field

[0001] The utility model belongs to the technical field of chemical equipment, in particular to a reaction kettle for separating and extracting heavy metals from industrial wastewater. Background Art

[0002] Extraction, also known as solvent extraction or liquid-liquid extraction, is a unit operation that uses the different solubilities of components in the system in the solvent to separate the mixture. That is, it uses the different solubilities or distribution coefficients of substances in two immiscible solvents to transfer the solute from one solvent to another. In industrial wastewater, heavy metal pollution is a serious pollution problem. In practice, factories will use extraction reactors to extract heavy metals from industrial wastewater to reduce heavy metal pollution.

[0003] In the existing extraction reactor, the extractant and wastewater need to be fully mixed to achieve sufficient extraction. When the extraction reactor is separating liquids, the staff needs to separate the liquids through the observation window to observe the internal situation. However, the inside of the reactor is dark, and the staff often cannot separate the liquids very accurately. Utility Model Content
