Description

Technical Field

[0001] This utility model relates to the field of extraction and oil removal technology, and in particular to an adsorption filtration system. Background Technology

[0002] In the wet process of nickel and cobalt salt production, the extractant acts as a chemical agent to react with the metal being extracted, forming an extractant that is extracted into the organic phase. It can also be used in a chemical reaction to extract the metal from the organic phase into the aqueous phase, thus achieving metal purification and enrichment. However, in this process, the extractant and the aqueous phase are mutually soluble, which affects extraction production and product quality. Currently, to prevent the mutual dissolution of the extractant and the aqueous phase, sufficient settling time is provided to ensure that most of the extractant separates from the aqueous phase. However, some broken-chain extractant still dissolves in the aqueous phase. While using a resin column to adsorb the dissolved extractant can remove oil to below 3 ppm, the subsequent treatment cost of the resin column is high, resulting in a large initial investment. Using an oil separator can remove some oil, but only oil floating on the surface of the solution, and cannot effectively remove dissolved oil.

[0003] For example, patent CN220579349U provides an oil removal device for the extraction and production of nickel and cobalt salts; the oil removal device for the extraction and production of nickel and cobalt salts includes a first filter, an aeration tank, an oil-water separator, a settling tank, an activated carbon device, and a second filter connected in sequence, wherein the aeration tank is equipped with multiple aerators for aerating bubbles.
