炼厂322℃工艺气余热换热器的结构设计

毕业设计理论是学生理论联系实际的一次很好的机会，本次实验就炼厂322℃工艺气余热换热器进行一次毕业设计，掌握并了解在工业生产中节能、高效、环保等概念。

    换热设备在炼油、石油化工以及在其他工业中使用广泛，它适用于冷却、冷凝、加热、蒸发和废热回收等各个方面。

    其中，炼厂322℃工艺气余热换热器虽然在换热效率、设备的体积和金属材料的消耗量等方面不如其他新型的换热设备，但它具有结构坚固、弹性大、可靠程度高、使用范围广等优点，所以在各工程中仍得到普遍使用。

    炼厂322℃工艺气余热换热器的结构设计，是为了保证换热器的质量和运行寿命，必须考虑很多因素，如材料、压力、温度、壁温差、结垢情况、流体性质以及检修与清理等等来选择某一种合适的结构形式。

 

    Graduation design theory is a theory with practice students a great opportunity, this experiment on 322 ℃ refinery process gas heat exchanger once graduation, grasp and understand the industrial production of energy-saving, efficient, environmentally friendly concepts.

     Heat transfer equipment in oil refining, petrochemical and other industries widely used, it is suitable for cooling, condensing all aspects of heating, evaporation and waste heat recycling.

     Among them, 322 ℃ refinery process gas heat exchanger, although not in the heat transfer efficiency, the volume of equipment and consumption of metallic materials and other aspects of other new heat transfer equipment, but it has a solid structure, flexibility, high reliability, use a wide range of advantages, it is still in the works universal use.

     322 ℃ refinery process gas heat exchanger structural design, the heat exchanger is to ensure the quality and operating life, you must consider many factors, such as material, pressure, temperature, wall temperature, fouling situation, as well as maintenance and fluid properties cleanup, etc. to select one appropriate structure.

    For the same form of the heat exchanger, due to the different conditions, often using not the same structure. In engineering design, in addition to try to use styling products, but often their specific conditions designed to meet the needs of workmanship (get the most reasonable conditions for the most effective and most economical to facilitate manufacturing heat exchangers and many more).

Key words: heat exchanger; shell and tube heat exchanger; process gas
