High pressure reactor (magnetic high-pressure reactor) is a typical innovation of magnetic transmission device applied to reaction equipment. It fundamentally solves the shaft seal leakage problem that can not be overcome by packing seal and mechanical seal, without any leakage and pollution. It is the most ideal device for chemical reaction under high temperature and high pressure in China, especially for flammable, explosive The chemical reaction of toxic medium shows its advantages.
The reactor is a comprehensive reaction vessel. The structure, function and accessories of the reactor are designed according to the reaction conditions. From the beginning of feed reaction discharge, the preset reaction steps can be completed with a high degree of automation, and the important parameters such as temperature, pressure, mechanical control (stirring, blowing, etc.) and reactant / product concentration in the reaction process can be strictly controlled.
Its structure is generally composed of kettle body, transmission device, mixing device, heating device, cooling device and sealing device. Corresponding auxiliary equipment: fractionation column, condenser, water separator, collection tank, filter, etc.
Then high pressure reactor and ordinary reactor belong to the same category of reactor, but their material composition can be different.
The autoclave body is mainly made of 1cr18ni10ti stainless steel, and titanium (TA2), nickel (Ni6) and composite steel plate can be made according to the requirements of different media. The autoclave body structure has flat cover, convex cover and closed reactor body with manhole. The opening on the autoclave cover can be designed according to the requirements of users; The heating methods include jacket steam, jacket hot oil and electric heating, which can be selected by users when ordering.
The inner surface of the kettle with polishing requirements can reach the above mirror polishing level, and the materials with high viscosity can be processed into a conical bottom, which is convenient for discharging and cleaning.
The reactor materials generally include 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. Agitators include anchor type, frame type, paddle type, turbine type, scraper type and combined type. The rotating mechanism can adopt cycloidal needle wheel reducer, stepless speed reducer or variable frequency speed regulation, which can meet the special reaction requirements of various materials.
The reactor sealing device can adopt mechanical seal, packing seal and other sealing structures. Jacket, half pipe, coil, Miller plate and other structures can be used for heating and cooling. The heating methods include steam, electric heating and heat transfer oil to meet the process needs of different working environments such as acid resistance, high temperature resistance, wear resistance and corrosion resistance. Moreover, it can be designed and manufactured according to the process requirements of users.
