The reactor is a comprehensive reaction vessel. According to the reaction conditions, the structure, function and accessories of the reactor are designed. The pre-set reaction steps can be completed with a high degree of automation from the beginning of feed reaction discharge, and the important parameters such as temperature, pressure, mechanical control (stirring, blowing, etc.), reactant / product concentration and other important parameters in the reaction process can be strictly controlled. Generally, the materials of the reactor are carbon manganese steel, stainless steel, zirconium, nickel base (Hastelloy, Monel) alloy and other composite materials. The reactor can be made of SUS304, SUS316L and other stainless steel materials. The agitators are anchor type, frame type, paddle type, turbine type, scraper type and combined type. The rotating mechanism can be cycloid pinwheel reducer, stepless speed reducer or frequency conversion speed regulation, which can meet the special reaction requirements of various materials.
