Abstract

The invention discloses a shell-and-tube heat exchanger. By the shell-and-tube heat exchanger, heat exchange between two types of liquid can be implemented effectively; the shell-and-tube heat exchanger has temperature difference compensation ability; and the circumstance that the heat exchanger is damaged due to over large temperature difference stress between a shell and heat exchanging tubes can be avoided. The shell-and-tube heat exchanger comprises a tube pass portion, a shell pass portion and a plurality of supports, wherein the tube pass portion comprises a tube pass inlet tube, a tube pass outlet tube and a plurality of heat exchanging tubes; the shell pass portion comprises a heat exchanger outer shell, a shell pass inlet tube and a shell pass outlet tube; the heat exchanger outer shell consists of an end socket, a shell head and a channel; a fixing tube plate is arranged between the shell head and the channel; an end socket tube plate is arranged between the end socket and the channel; the inside of the shell head is divided into a tube pass flow inlet cavity and a tube pass flow outlet cavity by a tube pass flow separating plate; and the channel is provided with an expansion joint. The shell-and-tube heat exchanger has the advantages that the position of the expansion joint easily deforms, a structural temperature difference compensating effect is achieved by the slidable end socket tube plate, and structural damage caused by over large temperature difference stress is avoided.

Description

technical field

[0001] The invention belongs to the technical field of chemical heat exchange, and in particular relates to a shell and tube heat exchanger. Background technique

[0002] Heat exchangers are process equipment for heat transfer and are widely used in oil refining, petrochemical industries, and other general chemical industries. Examples include cooling, condensation, heating, evaporation, and waste heat recovery. Due to the diversity of use conditions (corrosion, temperature, pressure, medium, impurities, heat exchange capacity, etc.), heat exchangers also need to have a reasonable structure and form.

[0003] Tube-and-tube heat exchanger (tube-and-tube heat exchanger) is one of the most widely used heat transfer equipment at present. It exchanges heat between two liquids in the following way: one liquid flows through the shell and the heat exchange tube , another liquid flows through the heat exchange tube, and the heat exchange is performed inside and outs...
