Abstract

The invention discloses a star-star type three-phase induction heat reactor, and belongs to the technical fields of chemical engineering, food and environments. The star-star type three-phase induction heat reactor comprises a three-column magnetic circuit, a magnet exciting coil, magnetic coupling tubes and reaction cavities, wherein an injection port and a sample outlet are formed in the joint intersections of the groups of the magnetic coupling tubes or the groups of the reaction cavities; Each group of the magnetic coupling tubes and each group of the reaction cavities is of three-phase star joint, and the groups of the magnetic coupling tubes and the groups of the reaction cavities are connected in a star-star structure; higher effective potential difference can be generated by an electrically conductive material or a reaction medium inside the reaction cavities, the effective potential difference comes from the line voltage of a three-phase circuit, the value is square root of 3times of normal phase voltage, and then the temperature rise efficiency of feed liquid or the reaction medium is higher, no external heat source or radiation is realized, sample are efficiently heatedunder the effect of no eternal electrode, and the star-star type three-phase induction heat reactor is provided with the single injection port and sample outlet, the liquid holdup of the reaction cavity is large, and the handling capacity is relatively high under the same sampling flow rate.

Description

technical field [0001] The invention relates to a star-star three-phase induction thermal reactor, which belongs to the technical fields of chemical industry, food and environment. Background technique [0002] Magnetic permeability is a physical quantity that characterizes the magnetism of magnetic media; it indicates the resistance to magnetic flux generated in space or the coil in the magnetic core material after the current flows through it, or its ability to conduct magnetic lines of force in the magnetic field. When a substance with magnetic permeability is placed in an alternating magnetic field, it will respond to the alternating magnetic field, and an induced current will appear, which in turn will cause a thermal effect, which is called the eddy current effect. [0003] According to the above principles, the premise of using the eddy current effect to heat the substance is that the substance has a magnetic permeability; for substances with a magnetic permeability c...
