[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 impact 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

Embodiment Construction

[0034] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] In this article, if there is no special explanation, when it comes to formulas, " / " means division, and "×" and "*" mean multiplication.

[0036] 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.

[0037] Such as figure 1 A shell-and-tube heat exchanger is shown, and the shell-and-tube heat exchanger includes a shell 4, a heat exchange tube 6, a tube-side inlet pipe 12, a tube-side outlet pipe 13, a shell-side inlet connecting pipe 14 and a shell The outlet connecting pipe 15; the heat exchange tube bundle composed of a plurality of parallel heat exchange tubes 6 is connected to the front tube sheet 3 and the rear tube sheet 7; the front end of the fr...

Abstract

The present invention provides a gas-liquid two-phase flow multi-tube shell-and-tube heat exchanger, which includes a shell, the two ends of the shell are respectively provided with heads, and the connection position between the head and the shell is set with a tube plate, The vapor phase in the tube-sheet vapor-liquid two-phase flow at both ends of the heat exchange tube can be condensed into a liquid phase during the heat exchange process. The heat exchange tube is equipped with a flow stabilization device for shock and noise reduction. The same heat exchange tube A plurality of flow stabilizing devices are provided, and the distance between adjacent flow stabilizing devices gradually increases along the flow direction of the fluid in the heat exchange tube. The invention provides a method of changing the length of the flow stabilizing device, when the gas-liquid two-phase flow exists in the pipeline, the vibration of the pipeline can be weakened to the greatest extent, the noise level can be reduced, the flow resistance can be reduced, and the uniformity of heat exchange can be 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 impact 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] Therefore, aiming at the ...
