Device and method for mixing and sedimentation processes of extraction with solvent for recovery of high purity products.

摘要

Device and method for mixing and sedimentation processes of solvent extraction for the recovery of the products of high purity.The invention relates to a method and a device used for the mixing and sedimentation processes of solvent extraction for the recovery of highly pure products.The device of the invention includes the following new features in each device of mixing / sedimentation: (a) agitators of the turbine side blind; (b) a degree of decreasing agitation to longThe length of the cascade; (c) a bulkhead door equipped with a window which is arranged at the center of the device interface of the sedimentation.It is located behind the shock absorbers to flow; and (d) a bulkhead without the window that is arranged in the center of the device interface of the sedimentation.It is located behind the bulkhead door equipped with a window.The elements mentioned above can be used to perform a method of operation which inhibits the secondary dispersion.Thus reducing the formation of micro droplets without affecting the mass transfer between the phases.As a result, the invention allows the separation of phase with such small amounts of drag you make possible a substantial increase in the quality of the product.And is an aqueous extract of ultra pure and is reduced, simultaneously, the surface of sedimentation is requested.
