Embodiment Construction

[0025] Carry out further detailed description below in conjunction with accompanying drawing:

[0026] figure 1A structural schematic diagram of the present invention is given, a shell-and-tube heat exchanger with a tree-shaped characteristic heat exchange tube bundle, which is composed of a tree-shaped heat exchange tube bundle, a shell, and a tube sheet. The specific structure includes: left head 1, left tube plate 2, branch connecting pipe 3, main connecting pipe 4, bifurcated connecting pipe 10, shell 5, tree-shaped heat exchange tube bundle 6, right tube plate 7 and right seal The first 8 and other main parts. The tube plates 2 and 7 are arranged at both ends of the shell, and the tree-shaped heat exchange tube bundles 6 are arranged in layers along the axial direction of the shell, and the main communication pipes 3 located on both sides of the tree-shaped heat exchange tube bundles are at both ends of the shell Pass through the tube sheets 2, 7 and be welded or expand...

Abstract

The invention discloses a shell-tube heat exchanger which comprises a shell body, a heat exchange tube bundle, a tube plate and an end enclosure; the tube plate and the end enclosure are arranged on both ends of the shell body, both ends of the heat exchange tube bundle are fixed on the tube plate and pass through the same, and the heat exchange tube bundle is in a tree-shaped structure; the heatexchanger comprises a main communication channel, branch connection pipelines and branch communication pipelines, the main communication pipeline at least comprises 2 sections, two opposite ends of the adjacent two sections are provided with the branch connection pipelines, and the branch connection pipelines on both ends are connected with the branch communication pipelines. The deployment method of the tree-shaped heat exchange tube bundle makes full use of the internal space of the shell, omits the deflector, and eliminates the possible flowing heat exchange dead area in a shell side space. The factors not only make the structural design of the whole heat exchanger compact and reasonable, but also realize the field synergy of fluid heat exchange among pipe shell sides, so as to greatlyimprove the heat effectiveness of a sleeve-type heat exchanger, and achieve the purposes of high-efficiency heat exchange and energy saving.

Description

technical field [0001] The invention relates to a heat exchange device, in particular to a shell-and-tube heat exchanger designed for improving heat exchange performance and having heat exchange tube bundles with configuration tree structure characteristics. Background technique [0002] Shell-and-tube heat exchangers have the advantages of high reliability, strong adaptability, firm structure, and simple manufacture, and are widely used in petrochemical, electric power, environmental protection and other industrial fields. With the advancement of industrial energy conservation and emission reduction, it will be of great engineering value and significance to adopt active and effective energy conservation measures in all links involving energy consumption. Optimizing the design of shell-and-tube heat exchangers to improve their heat exchange efficiency is an important measure for energy saving and emission reduction. [0003] A shell and tube heat exchanger usually consists ...
