Understanding: "Reactor"

The reactor can be made of stainless steel such as SUS304 and SUS316L. The stirrer has anchor type, frame type, paddle type, turbine type, scraper type, combined type, and the rotation mechanism can use a cycloidal pin wheel reducer to meet the special reaction requirements of various materials. Stepless speed reducer, sealing device can use mechanical seal, heating and cooling can be jacket, half pipe, coil, Miller plate and other structures, heating methods are steam, electric heating, thermal oil, to meet the acid, high temperature, Wear-resistant, anti-corrosion and other work environments require different processes. Can be designed and manufactured according to the user's process requirements.

Reactor conditions of use

According to the purpose of the stirring process and the flow state caused by the stirrer, it is a comparative method to judge the suitable slurry type for this [1] course.

Due to the Soviet Union's choice of slurry type in its own country, it is not the same as the slurry type used in China.

Advancing the slurry type divides the slurry type into two types, the fast type and the slow type. The former is operated in a turbulent state and the latter is operated in a laminar state.

When the reactor is selected, the slurry type and the baffle conditions are determined according to the purpose of stirring and the flow state. The determination of the flow state is affected by the viscosity of the stirring medium. The conditions of use are more specific, not only for the purpose of slurry type and stirring, but also for the range of viscosity of the propellant, the range of stirring speed, and the capacity range of the tank. The selection table proposed is also based on the purpose of stirring and the state of flow during stirring, and its advantage lies in the fact that the range of use of the slurry type is divided according to the characteristics of different stirring processes, making the selection more specific.

Comparing with the above table, we can see that the basis and result of reactor type selection are still relatively consistent. The following describes some of the major processes.

Reactor application

Reactors are widely used in petroleum, chemical, rubber, pesticides, dyes, medicines, foods, pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, alkylation, polymerization, and condensation, such as reactors, reaction vessels, decomposition pots. , Polymerization kettles, etc.; materials are generally carbon-manganese steel, stainless steel, zirconium, nickel-based (Hai's, Monel, Inconel) alloys and other composite materials.

Reactor use and characteristics

The general understanding of the reactor is that there is a physical or chemical reaction stainless steel container, through the structural design and parameter configuration of the container, to achieve the process requirements of heating, evaporation, cooling and low-speed mixing function. The pressure requirements during the reaction process also have different design requirements for the container. Production must be processed, tested and tested in strict accordance with the relevant standards. Stainless steel reactors vary according to different production processes, operating conditions, etc. The design structure and parameters of the reactors are different, that is, the structural styles of the reactors are different and belong to non-standard container equipment.

Stainless steel reactors are widely used in petroleum, chemical, rubber, pesticide, dye, medicine, food and other production users and various research projects for the research, used to complete the hydrolysis, neutralization, crystallization, distillation, evaporation, storage, hydrogenation, Containers for processes such as alkylation, polymerization, condensation, heating compounding, isothermal reaction, and the like.

The reaction vessel is a comprehensive reaction vessel, and the design of the structure and function of the reaction vessel according to the reaction conditions. From the beginning of the feed-reaction-discharge, the pre-set reaction steps can be completed with a high degree of automation, and the temperature, pressure, mechanical control (stirring, blowing, etc.), reactants/products during the reaction process can be completed. Concentration and other important parameters are strictly controlled.

The material of the reactor is generally carbon-manganese steel, stainless steel, zirconium, nickel-base (Hastellob, Monel) alloys and other composite materials. The reactor can be made of stainless steel such as SUS304 and SUS316L. The agitator has anchor type, frame type, paddle type, turbine type, scraper type, combined type, and the rotation mechanism can use cycloid pin wheel speed reducer, stepless speed reducer or variable frequency speed regulation, etc., which can meet the special requirements of various materials. Reaction requirements. Sealing devices can use mechanical seals, packing seals and other sealing structures. Heating, cooling can be jacket, half pipe, coil, Miller plate and other structures, heating methods are steam, electric heating, thermal oil, to meet the acid, high temperature, wear resistance, corrosion resistance and other different working environment need. Can be designed and manufactured according to the user's process requirements.
