Description

Technical Field

[0001] The utility model relates to the technical field of reactor heating, in particular to a far-infrared heating reactor with uniform heating. Background Art

[0002] Reactors are broadly understood as containers for physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. Reactors are widely used in the fields of petroleum, chemical industry, rubber, pesticides, dyes, medicine and food. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization, condensation, etc., such as reactors, reaction pots, decomposition pots, polymerization kettles, etc.; the materials are generally carbon manganese steel, stainless steel, zirconium, nickel-based (Hastelloy, Monel, Inconel) alloys and other composite materials.

[0003] Traditional far-infrared heating reactors usually only use far-infrared heaters to heat the surface of the lower half of the reactor. The rotating shaft inside the reactor is located in the center. When the rotating shaft rotates to drive the stirring arm for stirring, different materials inside the reactor are subjected to different centrifugal forces due to different densities. Therefore, some materials with high density are more likely to be concentrated near the axis inside the reactor, and other materials with low density are closer to the side wall of the reactor and close to the far-infrared heater, which causes the heating rate of the materials inside the reactor to deviate, affecting the overall heating efficiency of the materials.
