原油-汽油浮头式换热器设计
[摘要]换热器是用于各种物料之间进行热量传递的过程设备。
在浮头换热器设计过程中，严格按照GB150-98《钢制压力容器》和GB151-99《钢制管壳式换热器》等标准进行设计和计算。
在本次的设计过程中，包括了两个部分：计算部分和绘图部分。计算部分主要是对筒体、封头、管板、换热管、法兰、折流板、拉杆、鞍座等进行了设计和选型,并且，对壳体和管箱进行了开孔补强计算，最终选择了浮头式换热器。除此之外，还参阅相关的设计手册及大量的文献，完成了一张总装配图和4张零件图的绘制。

Crude oil-?gasoline heat exchanger design
[Abstract] Heat exchanger in oil refining,petrochemical,andwidely used in other professions,it is suitable for cooling,heating,evaporation and condensation,heat recovery,andvarious other aspects.
Among them,shell-and-tube heat exchanger in the heat transfer efficiency,size of equipment and metal consumption than other new type of heat-exchange equipment,but it has a strong structure,flexibility,high reliability,widely used and so on,so the project is still beingwidely used.
Structure design of shell-and-tube heat exchanger,is to ensure that the heat exchanger and the quality of life,you must consider many factors,such as material,pressure,temperature andwall temperature difference,scaling,fluid properties,aswell as maintenance and cleaning,and so on to choose an appropriate structure.
With a form of heat exchangers,for avariety of conditions,often used structures are not the same.
In the engineering design, in addition to the series of training as much as possible, it is often designed according to its own specific conditions to meet the needs of the technology(the most efficient and economical manufacturing of heat exchangers supported by the most reasonable and appropriate conditions, So on).
