Embodiment Construction

[0033] The specific implementation of the present invention will be further described in detail below in conjunction with the embodiments and drawings, but the present invention is not limited.

[0034] The novel baffle rod longitudinal flow shell-and-tube heat exchanger provided by the present invention is an adjustable baffle rod longitudinal flow shell-and-tube heat exchanger, and its structure is as follows: Figure 1 to Figure 6 As shown, it includes: a shell 8, a heat exchange tube 5 located in the inner cavity of the shell 8, a tube plate connected to both ends of the shell 8 by bolts, and a certain distance (for example, 0.5 meters) arranged in the shell 8 The baffle rod 7.

[0035] The tube sheets at both ends of the shell 8 are respectively the left tube sheet 3 and the right tube sheet 10 , wherein: the left tube sheet 3 is connected to the left end cover 2 with the tube-side fluid inlet 1 by bolts. The right tube plate 10 is connected with the right end cover 11 h...

Abstract

The invention provides a novel baffle rod longitudinal flow shell-and-tube heat exchanger, which includes heat exchange tubes (5) and baffle rods (7) located in the inner cavity of the shell (8), the baffle rods (7) There are multiple groups, uniformly distributed and arranged at intervals, and each group of baffle rods can rotate around the axis of the elliptical cylinder of the baffle rods. The invention can change the flow state of the shell-side fluid by adjusting the special structure baffle rod, and can adjust the heat exchange capacity of the heat exchanger within a certain range; , change the turbulence intensity of the shell-side fluid, and adjust the parameters such as the temperature and pressure of the fluid outlet to meet the needs of different working conditions in actual work. The invention has the advantages of simple structure, convenient adjustment, wide application range and the like.

Description

technical field [0001] The invention relates to a longitudinal flow shell and tube heat exchanger, in particular to a baffle bar longitudinal flow shell and tube heat exchanger with adjustable heat exchange capacity within a certain range. Background technique [0002] As a kind of heat exchange equipment, heat exchanger has been widely used in chemical industry, aerospace, refrigeration, air conditioning, metallurgy and other industries. Compared with other types of heat exchangers, shell and tube heat exchangers have the characteristics of mature technology and reliable structure, and are most widely used in industry. Based on the difference in the direction of fluid movement in the tube side and the shell side, shell and tube heat exchangers can be divided into cross flow and longitudinal flow heat exchangers. Due to the long development time and mature preparation process of cross-flow shell-and-tube heat exchangers, most of the shell-and-tube heat exchangers used in in...
