Abstract

The present invention discloses a circulating magnetoelectric-induction reaction system and application thereof. The system comprises an alternating induction voltage unit, an alternating induction magnetic field unit, a low-frequency power supply, and a feed liquid container. The alternating induction voltage unit is mainly composed of a closed iron core, a primary coil, a secondary coil, and an induction voltage cavity. The alternating induction magnetic field unit is mainly composed of a C-shaped iron core, a primary coil, and a magnetic field cavity. The low-frequency power supply is connected to the primary coils in the alternating induction voltage unit and the alternating induction magnetic field unit and provides excitation voltage for the primary coils. The secondary coil comprises an insulating pipeline, which serves as a feed liquid circulating pipeline, and has both ends exposed out of the induction voltage cavity, with one end as a feed inlet and the other as a discharge outlet. The feed liquid container communicates with the feed liquid circulating pipelines in the alternating induction voltage unit and the alternating induction magnetic field unit to form a feed liquid circulation loop. Through the application, continuous-flow processing can be achieved, electrochemical reaction and ionic polarization can be avoided, and production and processing can be conducted efficiently and rapidly in a large scale.
