Embodiment 1

[0051] Such as figure 1 and figure 2 , a schematic diagram of the overall structure of a double-channel heat exchanger in a fully-enclosed channel continuous spiral baffle heat exchanger with an axial support plate structure includes: a tubular shell 5 with twelve supports 2 inside, and supports 2 Rotate one side of the coaxial side on a plane with α=180° fixedly connected by two support plates to form a support 2 with a rhombus structure, in which the support 2 at both ends is 1 / 2 each, and all the supports end to end Then rotate the adjacent supports 2 at an angle of β=90° according to the right-handed spiral method, and then use the baffles 3 to rotate the 24 baffles 3 on both sides of the two adjacent supports according to the right-handed spiral method. Corner closed fixed connection, a number of heat exchange tubes pass through the through holes on the baffle, and then through the limit inlays 12 at both ends and the vertical fixed connection of the tube plate 7, and f...

Abstract

The invention provides a heat exchanger which comprises a tubular shell, a shell pass inlet, a shell pass outlet, a limit inlay, a tube pass inlet and a tube pass outlet, wherein both ends of the shell are respectively provided with a tube box and a tube plate, and a heat exchange tube and a baffling plate are arranged in the shell; the shell pass inlet and the shell pass outlet are formed in the tubular shell and axially vertical to the tubular shell; the tube pass inlet and the tube pass outlet are formed in the tube box; and a spiral flow guide ring is respectively arranged at the shell pass inlet and the tube pass inlet. According to the heat exchanger, a total-shell-pass nonlinear three-dimensional multi-runner spiral runner structural design is realized, so that the heat exchanger has the characteristics of high heat exchange efficiency, compact structure, easy machining, low maintenance cost, small vibration, long service life and the like and has wide application values in the fields of petrochemical industry, smelting, electric power, ship building, food, heat supply, energy saving and environmental protection; and particularly, under the condition of two-phase mixed media, the heat exchanger has the characteristics of strong homogenizing capacity and high heat exchange efficiency.

Description

technical field [0001] The invention belongs to the technical field of thermal energy engineering and heat exchangers, and in particular relates to a nonlinear spiral baffle heat exchanger based on an axial support plate. Background technique [0002] At present, the vertical bow-shaped baffle tube-and-tube heat exchanger commonly used in China has thorny problems such as flow stagnation, high pressure drop, easy vibration damage of the tube bundle, and easy deposition of dirt. The spiral baffle heat exchanger developed in recent years It is gradually being replaced. [0003] In the 1960s, the design idea of ​​the spiral baffle heat exchanger was born. In the 1980s, its industrial prototype, the discontinuous spiral baffle heat exchanger, was born. It is a quarter fan shape, and each baffle forms a certain angle with the axis of the shell, forming a semi-closed approximate spiral flow channel with the inner wall of the shell and the outer wall of the heat transfer tube. Thi...
