Abstract

The invention discloses a square shell-and-tube heat exchanger, which comprises a heat exchanger shell, an upper connector connected to the top of the heat exchanger shell, and a lower connector connected to the bottom of the heat exchanger shell. The shell is square with openings at both ends. The left side plate of the shell is a tube plate. The outer surface of the tube plate is connected with a semicircular tube bundle. The semicircular tube bundle includes a plurality of semicircular tubes that are not connected to each other; A row of U-shaped heat exchange tubes, the two connected ends of the heat exchange tubes are respectively connected to the two adjacent rows of tube holes in the tube sheet, and the two connected ends of the heat exchange tubes are respectively connected to two adjacent semicircular tubes The semicircular tube at the top of the semicircular tube bundle communicates with the liquid inlet, and the semicircular tube at the bottom communicates with the liquid discharge port; the heat exchange liquid enters the heat exchange tube through the liquid inlet and flows out from the liquid discharge port; the present invention can be used in the same More heat exchange tubes are connected at a lower length, which solves the problem of difficult sealing of multi-process heat exchange tubes.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a square shell-and-tube heat exchanger. Background technique [0002] The shell-and-tube heat exchanger includes a gas-liquid heat exchanger, that is, the heat exchange medium is gas, and the target medium is liquid. The conventional gas-liquid heat exchanger has fewer processes and is easy to seal. When the heat exchanger is large, the tube side structure is special, and the number of processes is large, the traditional structure cannot be sealed. [0003] The heat exchanger whose heat exchange medium is gas needs to ensure that the heat exchange medium can be fully utilized to prevent the heat exchange medium from flowing out without being used. How to ensure the sealing of large-scale heat exchangers and ensure the full utilization of heat exchange medium is a problem that we need to consider. Contents of the invention [0004] The purpose of the present invention ...
