Design of Fixed Tube-sheet Heat Exchanger
Abstract: The fixed tube-sheet heat exchanger is a kind of tube heat exchanger which is widely used as heat exchanger equipment in refrigeration. Two types of temperature difference liquid can have heat exchanging by used this device to achieve to reduce the temperature, which can guarantee can the guarantee next process unit's normal operation. This design researches fixed tube-sheet heat exchanger refrigeration system, through the blue print to determine the physical parameters of materials, then, combining with the working conditions, select the form of heat exchanger, what’s more, according to tasks to complete process parameters such as the heat exchange capacity, the total heat transfer coefficient, heat transfer area, at the same time, adjust accounts of the device. It calculates and selects bowl, tube channels, heads, tube sheets, flanges, baffles, supports, and ancillary equipments, moreover, does the necessary verification. The last work is drawing.
Key words: Fixed tube-sheet, heat exchanger, technological design
