Organic phase separation and recovery device and method capable of optimizing impurity filtering-out effect

Abstract

The invention provides an organic phase separation and recovery device and method capable of optimizing the impurity filtering-out effect. The organic phase separation and recovery device comprises a liquid feed filter, a liquid discharge filter, and at least two tanks communicated in sequence. Each tank is divided into an upper cavity and a lower cavity by a partition plate, perforated filter tubes are arranged on the partition plates and covered with a surface polymerization material, and the parts, located in the upper cavities of the tanks, of the perforated filter tubes are communicated with the corresponding lower cavities. PP filter elements are arranged in the liquid feed filter and the liquid discharge filter. The liquid feed filter, the tanks and the liquid discharge filter are communicated in sequence, and liquid flows in the liquid feed filter, the tanks and the liquid discharge filter from top to bottom to be treated. The tanks and the perforated filter tubes are made of glass fiber reinforced plastic, and the surface polymerization material is acrylic staple fiber obtained after surface modification and quenching and tempering treatment. Suspended matter and oil dirt in liquid are removed before and after organic phase separation treatment, and thus the organic phase separation treatment efficiency is improved; it is not needed to add agents for pretreatment in the organic phase separation treatment process, it not needed to add chemical additives, and high-precision separation of an oil-water mixture can be achieved.

Description

technical field [0001] The invention relates to sewage treatment technology, in particular to an oil-water separation device and a manufacturing method of the oil-water device. Background technique [0002] In hydrometallurgy production, solvent extraction is a method of separating, enriching or passivating metals, the essence of which is to transfer metal ions or their compounds from an aqueous solution to an organic phase immiscible with water, thereby obtaining The extracted solution is then back-extracted so that the metal ions dissolved in the organic phase re-enter the aqueous phase. During the extraction process, the organic phase and the water phase are mixed at a high speed for mass transfer, then after the water phase and the organic phase are separated, there will be four forms of organic phases: floating, dissolving, emulsifying, and precipitating in water. Existence will cause the loss of high extraction agent and the load in the production process of the back ...

AI Technical Summary

Problems solved by technology

[0009] Activated carbon has good adsorption capacity, and the effect is very good when dealing with solutions with low oil content, but when the solution has high oil content, it needs to be replaced frequently; The cost is very high, the workload of the replacement is heavy, the sanitary conditions are poor, and the replacement waste needs space for storage and processing

In addition, production must be interrupted when replacing activated carbon, and production must be replaced after the tank is emptied, resulting in a decline in production

[0010] In addition, the extract inevitably contains many impurities before and during the oil removal treatment, which affects the efficiency and process of the oil removal treatment.
