Embodiment Construction
[0037] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0038] In this article, if there are no special instructions, when it comes to formulas, " / " means division, and "×" and "*" mean multiplication.
[0039] It should be noted that, unless otherwise specified, the two-phase flow mentioned in the present invention is a gas-liquid two-phase flow, where the gas is an insoluble or poorly soluble gas, that is, the gas will not dissolve in the liquid during the heat exchange process.
[0040] 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 connector 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 ...

Abstract
The invention provides a shell-and-tube heat exchanger comprising a shell. Sealing heads are arranged at the two ends of the shell, pipe plates are arranged at the connection positions of the sealingheads and the shell, a heat exchange pipe is connected with the pipe plates at the two ends, a gas phase in gas-liquid two-phase flow is insoluble or poorly-soluble gas, in other words, the gas cannotbe dissolved in liquid in the heat exchange process, a separating device is arranged in the heat exchange pipe and is of a sheet-like structure, and the sheet-like structure is arranged on the crosssection of the heat exchange pipe; and the separating device is composed of square through holes and regular octagonal through holes, the side length of the square through holes is equal to the side length of the regular octagonal through holes, the four sides of each square through hole are the sides of four different regular octagonal through holes, and the four mutually-spaced sides of each regular octagonal through hole are the sides of four different square through holes. According to the heat exchanger with the separating device of the new structure, when the gas-liquid two-phase flow exists in the pipe, compared with the background art, heat transfer is further enhanced, vibration of the pipe is weakened, and the noise level is reduced.
Description
Technical field [0001] The invention relates to a shell-and-tube heat exchanger, in particular to a two-phase flow heat exchanger containing non-condensable gas. Background technique [0002] Two-phase flow heat exchange containing non-condensable gas is widely present in heat exchange devices. For example, non-condensable gas is mixed in the heat exchange process, or non-condensable gas generated due to aging of equipment during fluid transportation, as well as natural gas. Condensation of mixed media with different boiling points, air separation, mixed refrigerant refrigeration, petroleum or waste plastics cracking, production in the process of liquefaction (the main components are methane with boiling point -162℃, ethane with boiling point -88℃, propane with boiling point -42℃, etc.) The main technological process in industries such as material gas production. [0003] Due to the presence of gas phase in the heat exchange process of fluids containing non-condensable gases, the ...
