The chemical reactor is one of the core devices in chemical production, and the advanced degree of the technology has an important influence on the chemical production, and directly influences the investment scale and the production cost of the device.

At present, the chemical synthesis process is generally carried out by adopting a kettle type or tubular reactor, and the mass transfer and heat transfer efficiency of reaction materials is in a relatively low level, so that the chemical reaction is not favorably carried out. In order to improve the mass transfer efficiency of the reaction materials, the reaction materials are redistributed by a material distributor before entering the kettle-type and tubular reactors, so that the reaction materials are quickly mixed and transferred in the kettle-type and tubular reactors. However, the structure of the conventional material distributor is usually that one feeding hole corresponds to a plurality of discharging holes, so as to divide the reaction material into a plurality of strands, and although the volume of a single-stranded reaction material is greatly reduced, the single-stranded reaction material is usually columnar (when the reaction material is liquid in a chemical reaction), the reaction material located in the center of the columnar still needs a long time to mix and transfer, that is, the mass transfer efficiency of the reaction material is still low.
