Problems solved by technology

Due to the existence of a small amount of polymer, refining treatment cannot be used; natural sedimentation requires a large site and settling time, and has no industrial application value; direct centrifugal treatment, the intensification of emulsification and the extreme instability of the feed state make the centrifuge system completely not functioning properly
The production of the whole set of equipment was seriously hindered due to the problem of separation

Abstract

The invention relates to a liquid-liquid two-phase separation system for unsteady state feeding partial emulsification and application. The liquid-liquid two-phase separation system comprises a pre-separation tank, a collection tank, an extrusion demulsification device, a centrifuge and a recovery tank, the centrifuge is also communicated with a circulation tank, and the circulation tank is communicated with the pre-separation tank; the pre-separation tank is communicated with a separation liquid inlet pipe, and the separation liquid inlet pipe and the circulation tank respectively extend intothe bottom of the pre-separation tank through corresponding insertion pipes; a first baffle and a second baffle are arranged in the pre-separation tank, the first baffle is close to the insertion pipe, and the second baffle is close to one side of a heavy component assembly bag; and the pre-separation tank is communicated with a heavy component collection tank through a siphon. According to the invention, the production efficiency can be greatly improved, the separation thoroughness is improved, and the equipment size is reduced; meanwhile, only the separation degree of an outlet in one sideof the centrifugal machine needs to be improved to guarantee the separation precision, the operation condition of the other side does not need to be considered, the system operation stability and thefeeding adaptive capacity are greatly improved, and the working condition of large-range fluctuation can be met.

Description

technical field [0001] The invention belongs to the technical field of chemical production, and in particular relates to a liquid-liquid two-phase separation system for partial emulsification of unsteady feed and its application. Background technique [0002] Separation of two-phase and multi-phase liquid-phase mixtures is an essential processing skill in modern chemical production processes. For liquid phase mixing that requires a high degree of separation, modern chemical industry mostly adopts rectification for separation and purification. The notable feature is the high precision of the separated products, but the energy consumption is high, and the primary investment involved in the automatic control system is large. For the application fields that do not require high separation accuracy, especially the separation of the mixing system with low self-compatibility of the liquid phase, the density difference under the action of the gravity field is more often used for stat...
