Problems solved by technology

However, it was found during the operation of this device that the space A formed between the three pipes is relatively small because the pipes are tightly combined, because the space A is formed by the convex arc of the three pipes, so most of the space A The narrow space will make it difficu

Example Embodiment

[0044] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0045] In this article, if there are no special instructions, when it comes to formulas, " / " means division, and "×" and "*" mean multiplication.

[0046] It should be noted that, unless otherwise specified, the two-phase flow mentioned in the present invention is a vapor-liquid two-phase flow, where the vapor phase can be condensed into a liquid phase during the heat exchange process.

[0047] Such as figure 1 A shell-and-tube heat exchanger is shown, the shell-and-tube heat exchanger includes a shell 4, a heat exchange tube 6, a tube side inlet tube 12, a tube side outlet tube 13, a shell side inlet connection tube 14 and a shell Process outlet connector 15; a heat exchange tube bundle composed of a plurality of parallel heat exchange tubes 6 is connected to the front tube plate 3 and the rear tube plate 7; the front end of the front tube plate ...

Abstract

The invention provides a liquid-vapor two-phase flow tubular shell type heat exchanger. The heat exchanger comprises a shell, wherein the two ends of the shell are separately provided with end sockets, tube plates are arranged at the connecting positions of the end sockets and the shell, and heat exchange pipes are connected with the tube plates at the two ends; a vapor phase in liquid-vapor two-phase flow can be condensed into a liquid phase in the heat exchange process, and the liquid-vapor two-phase flow flows in a tube pass; and flow stabilizing devices used for reducing vibration and noise are arranged in the heat exchange pipes, a plurality of flow stabilizing devices are arranged in the same heat exchange pipe, and the length of the flow stabilizing devices is gradually reduced in the flowing direction of fluid in the heat exchange pipes. According to the heat exchanger provided by the invention, through the length variation of the flow stabilizing devices, when the liquid-vaportwo-phase flow occurs in the pipeline, the vibration of the pipeline is reduced to an utmost degree, and the noise level is reduced; and at the same time, flow resistance is reduced, and the heat exchange uniformity is improved.

Description

technical field [0001] The present invention relates to a shell-and-tube heat exchanger, and more particularly to a two-phase flow heat exchanger containing condensable gas. Background technique [0002] Vapor-liquid two-phase flow heat exchange widely exists in various heat exchange devices. Due to the existence of the vapor phase in the heat exchange process of vapor-liquid two-phase flow, the heat exchange efficiency will be low, the heat exchange will be deteriorated, and the fluid flow process will be unstable. , and will lead to the occurrence of water hammer phenomenon. When the gas-liquid phase of the two-phase working fluid is not uniformly mixed and flows discontinuously, the large-sized liquid mass will occupy the air mass space at high speed, resulting in unstable two-phase flow, which will violently impact equipment and pipelines, resulting in strong vibration and noise , which seriously threatens the safety of equipment operation. [0003] The inventor also d...
