Design of Two Parts and Shell-tube Heat Exchanger
Abstract：The heat exchanger is a heat transfer between the material energy-saving equipment，are widely used in petroleum，chemical，metallurgy，electric power， light industry，food industry. In recent years，with the development of energy-saving technology，heat exchanger applications continues to expand，which has brought significant economic benefits. As the most common type of heat exchanger shell and tube heat exchanger，particularly suitable for high-temperature and high-pressure applications，and the ability for a variety of heat and mass transfer，the most flexibility. The materials used by the upper and lower two parts and tube heat exchanger design shift gas and semi-water gas，the main raw material for synthetic ammonia，the upper and lower parts and tube heat exchanger is used in the nitrogen fertilizer plant. By tube box，cylinder，tube plate，head，deflector plates，the heat transfer tubes and other component parts. The design of the overall program to determine the physical parameters determine; thermodynamic calculation，calculation of resistance; detailed structure design; strength check. The design has been selected parts of the design of the device，such as housing，tube box，tube sheet shell and tube heat exchanger baffles，rod，stiffening ring. Including design calculations，material selection，sizing to determine the specific location，tube sheet thickness calculation，opening reinforcement calculation. For the baffle plate and rod baffle computer numerical simulation analysis.
