Problems solved by technology

[0003] The purpose of the present invention is to solve and overcome the excessive number of rows of fluid cross-flow tubes at the inlet and outlet of the shell side, the excessive increase of flow resistance, and the increase of fluid baffle dead zone in the existing heat exchanger after the equipment is enlarged, which leads to the heat exchanger. Heater operation energy consumption increases, heat transfer performance declines, equipment material consumption increases, and the problems and shortcomings of investment increase provide a fluid cross-flow through a small number of tube rows, low flow resistance, small fluid baffle dead zone, and heat transfer. The shell-and-tube heat exchanger with low energy consumption, good heat transfer performance, low equipment material consumption, and investment saving shell side multi-channel parallel flow inlet and outlet structure

Abstract

The present invention discloses a shell-and-tube heat exchanger with shell-side multi-channel parallel-flow inlet and outlet structure. It includes lower head, shell body, shell-side outlet, tube-side inlet, upper head, upper tube plate, heat-transferring tube bank, shell-side inlet, lower tube plate and tube-side outlet, and also includes shell-side inlet slot, inlet baffle plate, shell-side outlet slot, outlet baffle plate and longitudinal baffle plate.

Description

technical field [0001] The invention belongs to the field of shell-and-tube heat exchangers, in particular to a large-scale shell-and-tube heat exchanger with multi-channel parallel flow inlet and outlet structures. Background technique [0002] There are many shell-side structures of shell-and-tube heat exchangers, which are mainly divided into shell-side baffle heat exchangers and shell-side axial-flow heat exchangers. The shell-and-tube heat exchangers commonly used in industry with single-bow, double-bow or dish-ring baffles supporting tube bundles are shell-side baffle heat exchangers; industrially used baffle rods or hollow rings, etc. A shell heat exchanger is a shell side axial flow heat exchanger. The shell-and-tube heat exchangers of the above two shell-side structures all adopt a single-channel shell-side inlet and outlet structure. With the continuous enlargement of industrial equipment, the above-mentioned heat exchangers have the following defects: the heat ex...
