ABSTRACT
The heat exchanger is a very important energy-saving device that can greatly increase the efficiency of energy use. It is widely used in various fields such as petroleum, chemical industry, power, and metallurgy. It occupies a particularly important position in the national economy, especially in walking. Today, sustainable development has made energy conservation and environmental protection the main theme of industrial development. Heat exchangers are particularly important in the application of mitigation of energy shortages. Research institutions at home and abroad, universities and colleges have always attached
great importance to the study of heat exchangers.
According to the requirements of the mission statement, this design and design object is a F110 packing heat exchanger, which is mainly for the process calculation of the heat exchanger, the structure of the heat exchanger and the design of the strength. The main process of this design is divided into three parts. The first part is the process calculation part, which mainly consists of a given heat exchange area and other parameters. The heat exchanger is selected, the heat transfer coefficient is calibrated, and the required shell is calculated. The various parts of the structure, and the initial selection of various parameters of the structure, such as the size of the material, etc.; the second part is about the design and verification of the structure and strength, mainly for the stress calculation of the selected parts of the design; The part is to explain the manufacturing and installation of heat exchangers,
anti-corrosion and the maintenance of the later stage.
After repeated modification of the structural design parameters and drawing drawings, the design of the filler heat exchanger was completed.
