Description

technical field [0001] The invention relates to a star-delta three-phase induction thermal reactor, which belongs to the technical fields of chemical industry, food and environment. Background technique [0002] In the fields of chemical industry, food and environmental technology, it is often necessary to heat liquid samples and complete chemical reactions or treatments. Magnetothermal treatment is to generate eddy currents in materials with high magnetic permeability through an alternating magnetic field to generate heat; however, since the magnetic permeability of most liquid samples is low, close to zero, placing them directly in an alternating magnetic field cannot produce induction Electric current, that is, the eddy current effect, cannot realize the heating treatment of liquid samples by alternating magnetic field. [0003] Therefore, it is usually necessary to use an alternating magnetic field as an excitation source to heat a liquid through an iron-based material ...
