摘要（英）：

The utility model discloses a device for purifying phosphoric acid, comprising an extraction plant, a cleaning plant and a back extraction plant, wherein the extraction plant comprises two sets of blenders and phase separation plants, or one or more additional sets of blenders and phase separation plants, the cleaning plant comprises a set of blender and phase separation plant and a set of emulsifying machine and phase separation plant, or one or more additional sets of blenders and phase separation plants (or emulsifying machines and phase separation plants), the back extraction plant comprises two sets of emulsifying machines and phase separation plants, or one or more additional emulsifying machines and phase separation plants. A continuous-phase fluid inlet of the extraction plant is connected with a light-phase outlet of the final phase separation plant of the back extraction plant, a continuous-phase fluid inlet of the cleaning plant is connected with a final light-phase outlet of the extraction plant, and a primary solvent inlet of the back extraction plant is connected with a final light-phase outlet of the cleaning plant. The device for purifying phosphoric acid can strengthen mass transfer performance, increase purification efficiency, reduce equipment investment and running expense, and save floor space.
