Description

TECHNICAL FIELD

[0001] The utility model relates to a two-phase production technology field of hydrometallurgy, specifically relates to a device for improving oil phase recovery rate of hydmetallurgy. BACKGROUND

[0002] Two-phase mixing reaction is an important component in hydrometallurgical production, and is often applied to solution purification and separation such as extraction process. Extraction is a process of mixing and separating organic phase oil phase and ionic solution water phase, so as to purify the impurity content in ionic solution and obtain water solution meeting the requirements. In order to promote the speed of ionic separation, the two-phase mixing process is very intense, which leads to the difficulty of subsequent two-phase separation. According to the form of oil phase in water phase, it is generally divided into dispersed oil, suspended oil, emulsified oil and dissolved oil. In order to separate the two phases, a special two-phase separation process is often added in production to remove most of the oil, but it is difficult to separate completely, and the water solution still contains a certain amount of oil. Therefore, in order to further reduce the entrained oil in the water solution, a component can be added in the existing storage tank to realize the separation of oil and water and the recovery of oil phase again.

[0006] Further, the oil phase overflow tank comprises a bottom plate fixedly connected to the upper side wall of the inner side of the two-phase solution storage tank, and an oil phase overflow weir is vertically arranged at the end of the bottom plate away from the inner side wall of the two-phase solution storage tank.
