Embodiment

[0035] see Figure 1 to Figure 4 As shown, the present invention provides a single-tube-sheet heat exchanger, including a shell 101, and a baffle device and a plurality of heat exchange tubes 102 are arranged in the shell 101; the axial directions of the multiple heat exchange tubes 102 are parallel to each other; The baffle device includes a tie rod 103; a baffle 104 is fixed on the tie rod 103; a heat exchange tube 102 is installed on the baffle 104; two ends of the tie rod 103 are respectively fixedly connected with a support plate 105 to support the tie rod 103 and the baffle 104 .

[0036] Specifically, the outer surface of the heat exchange tube 102 is supported by the baffle plate 104, which avoids the situation that the heat exchange tube is too long and is easily broken due to force; the baffle plate 104 is fixed on the tie rod 103, and the baffle plate 104 cannot Relative movement occurs with the pull rod 103 , that is to say, the baffle 104 cannot move along the ax...

Abstract

The invention relates to the technical field of single-tube-plate heat exchangers, in particular to a single-tube-plate heat exchanger. The single-tube-plate heat exchanger comprises a shell, wherein a plurality of heat exchange tubes are arranged in the shell; the axial directions of the plurality of heat exchange tubes are parallel with each other; end sockets are arranged at the two ends of the shell, and a tube plate is arranged between the shell and the end sockets; stepped holes are formed in the tube plate, and the end parts of the heat exchange tubes penetrate through the stepped holes; the stepped holes comprise parts with large hole diameters and parts with small hole diameters, the parts with the large hole diameters are located at the side of the end sockets, and the parts with the small hole diameters are located at the side of the shell; and sealing assemblies are arranged at the parts with the large hole diameters of the stepped holes, and the sealing assemblies are arranged on the heat exchange tubes in a sleeving manner. The single-tube-plate heat exchanger provided by the invention has the characteristics of being wide in use range, low in mounting requirement, simple to repair, short in maintenance time and low in maintenance cost.

Description

technical field [0001] The invention relates to the technical field of single-tube-sheet heat exchangers, in particular to a single-tube-sheet heat exchanger. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers are common equipment in chemical industry, petroleum, power, food and many other industrial sectors, and play an important role in production. [0003] Among the existing heat exchangers, especially those using heat exchange tubes made of silicon carbide (i.e., silicon carbide tubes), the ends of the heat exchange tubes are fixed and sealed by two tube sheets, that is, Said that the ends of the heat exchange tubes are pierced on two tube sheets (the tube sheets are made of steel-lined polytetrafluoroethylene), and there is an O-ring set on the heat exchange tubes between the two tube sheets. Sealing is achieved by the clamping force of the two tube ...
