AI Technical Summary

Technical Problem

Existing hydraulic cavitation equipment is prone to premature and insufficient reaction when two fluids are mixed, resulting in low yield and by-product formation. Furthermore, it is difficult to achieve efficient mixing and reaction control, which limits its application in industrial production.

Method used

The liquid-liquid reactor, which adopts a dual-tangential reverse feeding structure and adjustable flow guide design, delivers two fluids through chambers A and B to form a swirling flow. The fluids are pretreated before entering the cavitation reaction unit. Combined with the flow guide and Venturi tube, it achieves efficient energy utilization and mixing.

Benefits of technology

It significantly improves reaction rate and selectivity, reduces energy consumption, and increases yield and purity, making it suitable for industrial applications in fields such as green chemistry, biorefining, and energy conservation and environmental protection.

Abstract

The present invention provides a hydrodynamic-cavitation-based liquid-liquid reactor and a method thereof, and an apparatus. The reactor comprises a chamber A and a chamber B, wherein the chamber A is configured to convey a first fluid so as to make same rotatably enter a cavitation reaction unit in a central region; the chamber B is configured to convey a second fluid so as to make same rotatably enter the cavitation reaction unit to mix with the first fluid; and an axially adjustable flow guide member is provided in the central region to assist with drainage. The present invention achieves high-efficiency mass transfer of multiphase fluids in a controllable cavitation field by means of an innovative dual-tangential reverse feeding structure, adjustable flow guidance and Venturi coupling design, forming reaction intensification through swirling flow impingement, mixing and cavitation collapse; moreover, intelligent regulation and control of a reaction path is achieved by means of the micro-injection of gas and flow field adjustment, thus significantly improving the reaction rate, selectivity and energy efficiency ratio. Thus, the present invention has good engineering adaptability and prospects for large-scale application.
