Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the industrial system has high requirements on the pressure resistance and heating temperature of the container. When the existing electromagnetic heating device heats the raw materials in the pressure-resistant container at high temperature, the container wall that generates eddy currents is prone to local mechanical damage and material damage. Fatigue, which reduces the pressure resistance of the container wall or even leaks; and then proposes an electromagnetic heating device that is not easily damaged by the pressure container wall

Description

technical field [0001] The invention relates to an electromagnetic heating device and a heating system using the electromagnetic heating device, belonging to the technical field of electromagnetic heating. Background technique [0002] Large-scale industrial production is inseparable from heat treatment. For example, in the pharmaceutical and chemical industry, liquids are heated to extract active ingredients or react, preheat gas reaction raw materials, and heat and bake semi-finished products. Large-scale heating devices generally use steam or heat transfer oil as the heat exchange medium. In addition to the heating device itself, steam heating devices and heat transfer oil heating devices also need to be equipped with fuel storage systems, boilers, steam or heat transfer oil circulation systems, and waste treatment systems. It also needs to be equipped with post-maintenance personnel, which makes the heating device using steam or heat transfer oil as the heat exchange med...
