What are the differences between high-pressure reactors and ordinary reactors? High pressure reaction kettle (magnetic high pressure reaction kettle) is a typical innovation in the application of magnetic transmission devices to reaction equipment. It fundamentally solves the problem of shaft seal leakage that cannot be overcome by previous packing seals and mechanical seals, without any leakage or pollution. It is currently an ideal device for chemical reactions at high temperatures and pressures in China, especially for chemical reactions in flammable, explosive, and toxic media, demonstrating its superiority.

The reaction kettle is a comprehensive reaction vessel, designed based on the reaction conditions for the structure, function, and configuration accessories of the reaction kettle. From the beginning of the feed reaction discharge process, the predetermined reaction steps can be completed with a high degree of automation, and important parameters such as temperature, pressure, mechanical control (stirring, blowing, etc.), and reactant/product concentration during the reaction process can be strictly controlled.

Its structure generally consists of a kettle body, a transmission device, a stirring device, a heating device, a cooling device, and a sealing device. Corresponding supporting auxiliary equipment: fractionation column, condenser, water separator, collection tank, filter, etc.

So high-pressure reaction kettle and ordinary reaction kettle belong to the same category of reaction kettle, but their material composition may be different.

The material of the high-pressure reaction kettle body is mainly made of 1cr18Ni10Ti stainless steel, and can be made of titanium (TA2), nickel (Ni6), and composite steel plates according to different media requirements. The kettle body structure includes a flat cover, a convex cover, and a closed reaction kettle body with a manhole. The openings on the kettle cover can be designed according to user requirements, and the heating methods include jacket steam, jacket hot oil electric heating, and other forms for users to choose from when ordering.

The inner surface of the kettle with polishing requirements can reach the above Bull polishing level, and the high viscosity materials can be processed into a conical bottom, which is convenient for feeding and cleaning.

The materials of the reaction kettle generally include carbon manganese steel, stainless steel, zirconium, nickel based (Hastelloy, Monel) alloy, and other composite materials. The reaction kettle can be made of stainless steel materials such as SUS304 and SUS316L. Agitators can be anchor type, frame type, paddle type, turbine type, scraper type, combination type, and the rotating mechanism can use cycloidal pinwheel reducer, stepless speed reducer, or variable frequency speed regulation, which can meet the special reaction requirements of various materials.

The sealing device of the reaction kettle can adopt sealing structures such as mechanical seals and packing seals. Heating and cooling can adopt structures such as jackets, half tubes, coils, Miller plates, etc. The heating methods include steam, electric heating, and thermal oil to meet the process needs of different working environments such as acid resistance, high temperature resistance, wear resistance, and corrosion resistance. And it can be designed and manufactured according to user process requirements.
