Embodiment Construction

[0035] The conical tube bundle support and the shell-and-tube heat exchanger using the tube bundle support of the present invention will be described in detail below with reference to the embodiments and drawings.

[0036] Such as figure 1 , figure 2 As shown, the cone-shaped tube bundle support structure for the shell-and-tube heat exchanger of the present invention is an olive-shaped structure with conical paraboloids 13 at both ends.

[0037] The cone angles of the conical paraboloids 13 at both ends of the olive-shaped structure are the same, or the cone angles of the conical paraboloids 13 at both ends of the olive-shaped structure are different.

[0038] Such as image 3 , Figure 4 As shown, the structure of the cone-shaped tube bundle support for the shell-and-tube heat exchanger of the present invention is a bullet-shaped structure in which one end is a conical paraboloid 13 and the other end is a plane 14 .

[0039] Such as Figure 5 , Figure 6 As shown, the ...

Abstract

The invention discloses a conical tube bundle support member and a shell-and-tube heat exchanger adopting the same. The support member is of an olivary structure with two ends being conical paraboloids, or a bullet structure with one end being a conical paraboloid and the other end being a plane. The shell-and-tube heat exchanger comprises a cylindrical shell and a plurality of heat exchange tubes, wherein two ends of the heat exchange tubes are axially arranged in the shell respectively through a left tube sheet and a right tube sheet; a plurality of conical tube bundle support members are arranged among the plurality of heat exchange tubes; and the plurality of heat exchange tubes and the plurality of conical tube bundle support members are drawn in and fixed by belt hoops. The plurality of heat exchange tubes are regularly distributed in a triangle or a square shape; and the conical tube bundle support members are arranged among the heat exchange tubes regularly distributed in the triangle or square shape. In the invention, the structure is simple, the manufacturing cost is low, and the single-shell side countercurrent heat exchange or double-shell side fluid heat exchange can be realized. The olivary support member changes the shell side fixed sectional area into shrink-expansion variable cross-section in axial flow, so that the heat convection capability of the shell side can be greatly improved.

Description

technical field [0001] The invention relates to a shell and tube heat exchanger. In particular, it relates to a conical tube bundle support for non-baffle plate and non-baffle rod, shell-side longitudinal flow shell-and-tube heat exchanger heat transfer enhancement and drag reduction-shock absorption and the use of the tube bundle support shell-and-tube heat exchanger. Background technique [0002] In the field of single-phase heat exchange, most of the shell-and-tube heat exchangers used in industry still use baffles as the tube support structure. There are many types of baffles, but no matter which one, they are different to varying degrees. There are defects such as large flow resistance on the shell side, induced vibration of the tube due to lateral flow, and unsatisfactory heat transfer effect. The baffle rod (or flat steel support bar) shell-and-tube heat exchanger proposed to improve the above shortcomings solves the vibration problem of the tube bundle through the ...
