The mechanical design of the reactor is performed after the process design. The conditions given in the process generally include: the kettle body volume, the maximum working pressure, the working temperature, the medium corrosivity, the heat transfer area, the stirring form, the rotation speed and the power, and the orientation of the process nozzle. These conditions are usually reflected in the mechanical design task book in the form of tables and diagrams. For mechanical design, the designer is responsible for rational selection, design, and calculation of vessels, agitator shafts, transmissions, shaft seals, etc. of stirred tank reactors based on the requirements and conditions proposed by the process design.
The mechanical design of the jacketed reactor generally follows the following content and steps:
(l) Overall structural design Considering manufacturing requirements, installation, and ease of use and maintenance, determine the structural type and dimensions of each part, such as the head type, heat transfer surface, transmission type, shaft seal, and various types of accessories. Wait.
(2) Select materials According to the pressure, temperature, and medium conditions, economical and reasonable material selection.
(3) Calculation of strength and stability Strength calculations and verification of the stability of the kettle head, jacket, and agitation shaft are to be performed.
(4) The selection of parts and components including the selection and design of motors, speed reducers, couplings, shaft seal types, and bases, bases, etc.
(5) Drawing drawings include assembly drawings and parts drawings. Standard parts have standard drawings to find the standard construction drawing number, not drawing.
(6) Put forward the technical requirements for the requirements of manufacturing, assembly, inspection and commissioning. The markable file number to which the standard technical conditions apply.
(7) Compilation of calculation instructions including demonstration of important issues in equipment design, mechanical calculation of main parts, and description of design selection of main parts.
