A multiphase mixing and separation device Technical Field

[0001] This utility model relates to a multiphase mixing and separation device. Background Technology

[0002] Extraction, also known as solvent extraction or liquid-liquid extraction, is a unit operation that separates mixtures by utilizing the different solubilities of components in a solvent.

It is widely used in chemical, metallurgical, and food industries, and is commonly used in the petroleum refining industry. Common extraction equipment includes mixers and clarifiers, extraction towers, and centrifugal extractors.

[0014] The present invention will be further described below:

[0015] In this invention, the aqueous phase and the organic phase enter the aqueous phase region and the organic phase region respectively. A stirring motor drives a stirring rod to agitate the phases. The suction force of the stirring draws the aqueous and organic phases from the two-phase confluence port into the stirring region for mixing. Then, the mixed phase enters the vortex channel from the mixed phase outlet. Under centrifugal force, the mixed phase flows within the vortex channel, and is separated step-by-step by phase-separating plates within the vortex channel. The organic phase flows out from the organic phase outlet pipe interface, while the aqueous phase enters the aqueous phase chamber of the aqueous phase regulator from the aqueous phase outlet. Rotating the regulating rod controls the gap between the end cap and the overflow hole, thereby controlling the rate at which the aqueous phase enters the regulating chamber, and ultimately controlling the discharge of the aqueous phase.

[0016] In this invention, a vortex channel is cleverly incorporated into the tank, and a phase separation plate is set within the vortex channel. This integrates the functions of the water phase regulator and the tank, eliminating the need for additional mixing chambers, separators, and clarification chambers. Compared with existing extraction equipment, this invention significantly reduces the floor space, volume, and manufacturing costs, thereby improving efficiency while reducing equipment investment and operating costs, and achieving cost reduction and efficiency improvement.
