Paper

The course project on the topic "Vertical vessel with stirrer" consists of 45 sheets of typewritten text and 2 sheets of graphic material in the format A1. Also, this project includes 3 sources of used literature.

The course design contains selection of structural materials of all elements of the apparatus, selection of bottoms and covers, determination of the design length of the shell, calculation of the shell under the influence of internal or external pressure, calculation of bottoms and covers under the influence of internal or external pressure, selection and calculation of flange joints of the shell, selection and calculation of supports, selection and calculation of connectors.

Introduction

Chemical devices are designed to carry out chemical, physical or physicochemical processes in them, as well as to store and mix and store various chemicals in them.

Depending on the purpose, most often in the process, chemical devices are called a reactor, heat exchanger, evaporator, condenser, hopper, etc.

Contained and recyclable substances in the apparatus are in different aggregate state, different chemical activity, from inert to very aggressive for maintenance personnel from harmless and toxic and in operation from safe to explosive.

Conclusion

As a result of the course project, a cylindrical bunker was calculated and designed. The knowledge and skills gained in studying the discipline at lecture and practical classes were also enshrined.

In turn, in the course project, the selection of structural materials was carried out, the selection of the bottom and cover, the determination of the design length of the shell, the shell was calculated under the influence of internal or external pressure, the bottoms and covers were calculated under the influence of internal or external pressure, the flange joints of the "shell were selected and calculated, the supports and nozzles were selected and calculated; calculated and studied methods of strengthening the technological openings of the vessel.
