Abstract

The invention provides a shell and tube heat exchanger. The shell and tube heat exchanger comprises a shell, wherein sealing heads are arranged at the two ends of the shell respectively, pipe plates are arranged at the joints of the sealing heads and the shell, heat exchange pipes are connected with the pipe plates at the two ends, and comprise outer pipes and core parts arranged in the outer pipes, and the core parts extend in the extension direction of the heat exchange pipes; the core parts are provided with electric heating parts, the same electric heating part in the same core part is divided into multiple sections, and the heating powers of different sections per unit length are different in the flowing direction of fluid in the heat exchange pipes. According to the shell and tube heat exchanger, by setting the mode that heating powers of different sections per unit length are different in the flowing direction of the fluid in the heat exchange pipes, the heating uniformity and heating efficiency are furthermore improved.

Description

technical field [0001] The invention relates to a shell-and-tube heat exchanger, in particular to a shell-and-tube heat exchanger for generating hot water at different temperatures. Background technique [0002] At present, the shell-and-tube heat exchanger is the most widely used heat exchanger structure in energy engineering projects, and its consumption accounts for 70% of the total heat exchanger consumption, which is a kind of partition heat exchanger. The shell and tube heat exchanger is characterized by firm structure and reliable use; it has a long history, and the technical links of manufacturing and use have reached maturity; it has high adaptability and a wide range of use. The shell side of a traditional shell-and-tube heat exchanger is heated by exchanging a cold source and a heat source. Generally, the temperature of one fluid is raised while the temperature of the other fluid is lowered. However, simultaneous heating of the two fluids at the same time cannot ...
