Abstract

The invention relates to the technical field of heat exchangers, and discloses a sectional shell-plate heat exchanger which comprises a shell. A tube pass inlet pipe is fixedly mounted at the top of the shell, a tube pass outlet pipe is fixedly mounted in the center of the bottom of the shell, and a shell pass inlet pipe is fixedly mounted on the right side of the bottom of the shell. A shell pass outlet pipe is fixedly installed on the upper portion of the right side of the shell, a tubular core body is installed on a sliding tube plate capable of moving up and down, the tubular core body and a plate type core body are connected through an upper tube box, an expansion joint and a lower tube box. The tubular core body has good high-temperature-resistant expansion performance compared with the plate type core body, when the tubular core body expands, the expansion displacement can be transmitted to the expansion joint by the sliding tube plate, so that the expansion difference between the tubular core body and the shell is eliminated, the high-temperature-resistant expansibility and reliability of the equipment are greatly improved, and the heat exchanger has the advantages of being novel in design, simple in structure, high in heat exchange efficiency and good in high-temperature-resistant expansibility.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a segmented plate-shell heat exchanger. Background technique [0002] As a kind of efficient and compact heat exchanger, the plate and shell heat exchanger has the advantages of high heat exchange efficiency, small temperature difference at the end, pressure drop, small footprint, low installation cost and equipment operation cost saving. It is used in oil refining, It is widely used in large-scale production equipment in chemical industry and other fields. [0003] However, in practical applications, we found that the traditional plate and shell heat exchanger still has some shortcomings. There is a large thermal tolerance difference between the structural parts with a larger cross-section and the thinner corrugated plate heat transfer elements in the plate bundle, and the temperature response speed is inconsistent. Due to large temperature fluctuations, a large thermal...
