Background

The shell and tube heat exchanger is the most widely used heat exchanger in chemical industry and alcohol production. It is mainly composed of a shell, a tube plate, a heat exchange tube, a seal head, a baffle plate and the like. The required material can be respectively made of common carbon steel, red copper or stainless steel. When heat exchange is carried out, a fluid enters from the connecting pipe of the end socket, flows in the pipe and flows out from the outlet pipe at the other end of the end socket, which is called a pipe pass; the other fluid enters from a connecting pipe of the shell and flows out from the other connecting pipe on the shell, and the other fluid is called shell side. The shell and tube heat exchanger has simple and compact structure and low cost, but the outside of the tube cannot be cleaned mechanically. The heat exchanger tube bundle is connected to tube plates, the tube plates are respectively welded at two ends of a shell, a top cover is connected to the tube plates, and fluid inlet and outlet connecting tubes are arranged on the top cover and the shell. Typically a series of baffles perpendicular to the tube bundle are placed outside the tube. At the same time, the connection between the tubes and the tube plate and the shell is rigid, and the two fluids with different temperatures are arranged outside the tubes. Therefore, when the temperature difference between the tube wall and the shell wall is large, the thermal expansion difference between the two causes large temperature difference stress, so that the tube is twisted or loosened from the tube plate, and even the heat exchanger is damaged.
