Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat exchangers, and particularly relates to a dual-function quench heat exchanger. BACKGROUND

[0002] The dual-function quench heat exchanger can realize two functions of heating saturated water or heating unsaturated water through heat exchange. Figure 1 As shown in the figure, the first function refers to heating saturated water to generate steam, at this time, the cooling medium enters the shell side inlet header 110 from the first inlet 111 and the second inlet 112, and then enters the device body 100 through multiple lower connection pipe openings 113 as evenly as possible. In the device body 100, the mixture of water and steam is generated by the heat exchange with the tube side heat medium (flowing in the heat exchange pipe), and then enters the shell side outlet header 120 through the upper connection pipe opening 123, and finally flows out of the device body 100 from the first outlet 121 and the second outlet 122. The second function refers to heating unsaturated water to increase the water temperature, at this time, the cooling medium enters the device body 100 from the right unsaturated inlet 101, and then flows to the left side of the device body 100 by bypassing the baffle, and finally flows out of the device body 100 from the unsaturated outlet 102.

[0003] However, under the second function, the heated unsaturated water enters the shell side inlet header 110 from the lower connection pipe opening 113 on the right side of the device body 100, and then flows back into the device body 100 from the lower connection pipe opening 113 on the left side, thereby bypassing the baffle, forming a short circuit of the device (a similar short circuit will also be formed in the shell side outlet header 120). Because a large amount of cooling medium does not pass through the baffle for full heat exchange with the heat medium, the heat exchange effect of the quench heat exchanger under the second function is poor, which cannot meet the process requirements.

[0004] Therefore, it is urgent to provide a dual-function quench heat exchanger to solve the above problems. SUMMARY

[0005] The present application aims to provide a dual-function quench heat exchanger, which can avoid the short circuit of the inlet header and the outlet header when the unsaturated medium flows, thereby reducing the heat exchange efficiency of the heat exchanger.

[0010] The outlet header has at least two second inlets and two second outlets on its side wall. The outlet header is connected to the cylinder through the second inlets, and the second outlets are used to discharge the saturated medium.

[0011] The regulating assembly includes a first regulating pipe and a second regulating pipe. The first regulating pipe is coaxially arranged with the inlet header and is placed inside the inlet header and rotatably connected to it. The first regulating pipe has a first through hole and a second through hole. The diameter of the first through hole is equal to and corresponds one-to-one with the inner diameter of the first inlet, and the diameter of the second through hole is equal to and corresponds one-to-one with the inner diameter of the first outlet. The second regulating pipe is coaxially arranged with the outlet header and is placed inside the outlet header and rotatably connected to it. The second regulating pipe has a third through hole and a fourth through hole. The diameter of the third through hole is equal to and corresponds one-to-one with the inner diameter of the second inlet, and the diameter of the fourth through hole is equal to and corresponds one-to-one with the inner diameter of the second outlet.

[0012] Preferably, the dual-function quench heat exchanger also includes a rotating assembly, which includes a first flange cover and a second flange cover.

The second flange cover is fixedly connected to one end of the second regulating pipe, and the second flange cover is detachably connected to one end of the outlet header via a flange.

[0013] Preferably, the rotating assembly may also include a third flange cover, which is fixedly connected to the other end of the first regulating pipe, and the third flange cover is detachably connected to the other end of the inlet header via a flange.

[0014] Preferably, the first regulating pipe is divided into a first pipe section and a second pipe section, with the first pipe section placed at one end of the inlet header and the second pipe section placed at the other end of the inlet header.

[0015] Preferably, the gap between the outer wall of the first regulating pipe and the inner wall of the inlet header is 1.5mm-2.5mm.

[0016] Preferably, the rotating assembly may also include a fourth flange cover, which is fixedly connected to the other end of the second regulating pipe, and the fourth flange cover is detachably connected to the other end of the outlet header via a flange.

[0017] Preferably, the second regulating pipe is divided into a third pipe section and a fourth pipe section, with the third pipe section located at one end of the outlet header and the fourth pipe section located at the other end of the outlet header.

[0018] Preferably, the gap between the outer wall of the second regulating pipe and the inner wall of the outlet header is 1.5mm-2.5mm.

[0019] Preferably, the first flange cover is circular, and the first flange cover is connected to one end of the inlet header by a plurality of first bolts, which are evenly distributed along the circumferential mid-span of the first flange cover.

[0020] Preferably, the second flange cover is circular, and the end of the second flange cover is connected to one end of the outlet header by a plurality of second bolts, which are evenly distributed along the circumferential mid-span of the second flange cover.

[0022] This invention provides a dual-function quench heat exchanger with a heat medium flowing through the tubes. The dual-function quench heat exchanger includes a cylinder, an inlet header, an outlet header, and a regulating assembly. The regulating assembly includes a first regulating pipe and a second regulating pipe. When heat exchange occurs between a saturated medium and a heat medium, the saturated medium enters the cylinder uniformly through the inlet header and flows out uniformly through the outlet header, completing heat exchange with the heat medium within the cylinder. When heat exchange occurs between an unsaturated medium and a heat medium, the first and second regulating pipes are rotated. The first regulating pipe's wall blocks the first inlet and the first outlet, preventing the unsaturated medium entering the cylinder from the unsaturated inlet from flowing through the inlet header. The second regulating pipe's wall blocks the second inlet and the second outlet, preventing the unsaturated medium from flowing out of the outlet header after heat exchange. This prevents short circuits at the inlet and outlet headers, ensuring the unsaturated medium must flow out of the cylinder through a baffle, thus facilitating smooth heat exchange and improving the heat exchanger's efficiency.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0039] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0041] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0042] This embodiment provides a dual-function quench heat exchanger to avoid a decrease in heat exchange efficiency caused by short circuits in the inlet and outlet headers during the flow of unsaturated media.

[0043] Specifically, such as Figures 2 to 5As shown, a dual-function quench heat exchanger with a heat medium flowing through the tubes includes a cylinder 200, an inlet header 300, an outlet header 400, and a regulating assembly. The cylinder 200 has an unsaturated inlet 210 and an unsaturated outlet 220 on its side wall, which are used to flow the unsaturated medium within the cylinder 200. The inlet header 300 has two first inlets 310 and at least two first outlets 320 on its side wall, connecting to the cylinder 200 via the first outlets 320. The first inlets 310 are used for the inflow of saturated medium, improving the uniformity of the saturated medium entering the cylinder 200 and increasing the heat exchange efficiency between the saturated medium and the heat medium. At least two second inlets 410 and two second outlets 420 are provided on the side wall of the outlet header 400. The outlet header 400 is connected to the shell 200 through the second inlets 410 and the second outlets 420 are used to discharge the saturated medium. Providing at least two second inlets 410 allows the heated steam to flow out of the shell 200 and into the outlet header 400 quickly through the second inlets 410, improving the flow of the saturated medium in the heat exchanger, thereby further improving the heat exchange efficiency between the saturated medium and the hot medium and preventing steam from accumulating on the upper part of the shell 200. The regulating assembly includes a first regulating pipe 510 and a second regulating pipe 520. The first regulating pipe 510 is coaxially arranged with the inlet header 300 and is placed inside the inlet header 300 and rotatably connected to it. The first regulating pipe 510 has a first through hole 511 and a second through hole 512. The diameter of the first through hole 511 is equal to and corresponds one-to-one with the inner diameter of the first inlet 310, and the diameter of the second through hole 512 is equal to and corresponds one-to-one with the inner diameter of the first outlet 320, facilitating the flow of the saturated medium before heat exchange at the inlet. The second regulating pipe 520 is coaxially arranged with the outlet header 400 for the inlet and outlet of the header 300. The second regulating pipe 520 is placed inside the outlet header 400 and rotatably connected to the outlet header 400. The second regulating pipe 520 is provided with a third through hole 521 and a fourth through hole 522. The diameter of the third through hole 521 is equal to and corresponds one-to-one with the inner diameter of the second inlet 410, and the diameter of the fourth through hole 522 is equal to and corresponds one-to-one with the inner diameter of the second outlet 420, which facilitates the entry and exit of the saturated medium after heat exchange in the outlet header 400.

[0044] When heat exchange occurs between a saturated medium and a hot medium, the saturated medium enters the cylinder 200 uniformly through the inlet header 300 and flows out uniformly through the outlet header 400, completing heat exchange with the hot medium within the cylinder 200. When heat exchange occurs between an unsaturated medium and a hot medium, the first regulating pipe 510 and the second regulating pipe 520 are rotated. At this time, the pipe wall of the first regulating pipe 510 blocks the first inlet 310 and the first outlet 320, so that the unsaturated medium entering the cylinder 200 from the unsaturated inlet 210 no longer passes through the inlet header 300. The pipe wall of the second regulating pipe 520 blocks the second inlet 410 and the second outlet 420, so that the unsaturated medium after heat exchange no longer passes through the outlet header 400. This prevents short circuits at the inlet header 300 and the outlet header 400, forcing the unsaturated medium to flow out of the cylinder 200 through a baffle, ensuring smooth heat exchange and improving the heat exchange efficiency of the unsaturated medium.

[0045] In this embodiment, there are 9 first outlets 320. In other embodiments, the number of first outlets 320 may be 2, 8, or 13, etc. In this embodiment, there are 9 second inlets 410. In other embodiments, the number of second inlets 410 may be 2, 7, or 14, etc.

[0046] Furthermore, the dual-function quench heat exchanger also includes a rotating assembly, which comprises a first flange cover 610 and a second flange cover 620. The first flange cover 610 is fixedly connected to one end of the first regulating pipe 510, and its end is detachably connected to one end of the inlet header 300 via a flange. Rotation of the first flange cover 610 enables the rotation of the first regulating pipe 510. The second flange cover 620 is fixedly connected to one end of the second regulating pipe 520, and its end is detachably connected to one end of the outlet header 400 via a flange. Rotation of the second flange cover 620 enables the rotation of the second regulating pipe 520. In this embodiment, the first flange cover 610 and the first regulating pipe 510 are welded together; in other embodiments, they may be bonded together. In this embodiment, the second flange cover 620 and the second regulating pipe 520 are welded together; in other embodiments, they may be bonded together.

[0047] Furthermore, when the inlet header 300 is relatively long, the rotating assembly may also include a third flange cover. The third flange cover is fixedly connected to the other end of the first regulating pipe 510, and the end of the third flange cover and the other end of the inlet header 300 are detachably connected via a flange. The cooperation between the third flange cover and the first flange cover 610 improves the smoothness of the rotation of the first regulating pipe 510. In this embodiment, the third flange cover and the first regulating pipe 510 are welded together. In other embodiments, the third flange cover and the first regulating pipe 510 may be bonded together.

[0048] Furthermore, such as Figures 6 to 8 As shown, the first flange cover 610 is circular, and its end is connected to one end of the inlet header 300 by multiple first bolts 611. These first bolts 611 are evenly distributed along the circumferential mid-span of the first flange cover 610. When heat exchange with unsaturated media is performed, the first bolts 611 are removed to separate the first flange cover 610 from the inlet header 300. The first flange cover 610 is then rotated by a certain angle (this angle is equal to the angle between two adjacent first bolts 611, or is an integer multiple of the angle between two adjacent first bolts 611), so that the positions of the first bolt holes 612 and the second bolt holes are re-aligned. The end of the first flange cover 610 is then reconnected to the inlet header 300, thereby achieving the purpose of rotating the first regulating pipe 510. In this embodiment, the number of first bolts 611 is 12. In other embodiments, the number of first bolts 611 can be 4, 8, or 16, etc. In this embodiment, the first flange cover 610 is rotated at an angle of 90 degrees. ° In other embodiments, the first flange cover 610 can rotate at an angle of 30 degrees. ° 60 ° Or 120 ° It should be noted that the rotation angle of the first flange cover 610 should not be 360 ​​degrees. ° This results in the pipe wall of the first regulating pipe 510 failing to seal the first inlet 310 and the first outlet 320. In other embodiments, the end of the first flange cover 610 and the inlet header 300 can also be fixed by magnetic attraction or by a snap-fit ​​structure. It should be noted that, in order to improve the convenience of rotating the third flange cover, the third flange cover is set as circular, and the end of the third flange cover and the other end of the inlet header 300 are connected by 12 third bolts. The 12 third bolts are evenly distributed along the circumferential center of the third flange cover, which will not be described in detail here.

[0049] Optionally, the first regulating pipe 510 is divided into a first pipe section and a second pipe section. The first pipe section is located at one end of the inlet header 300, and the second pipe section is located at the other end of the inlet header 300. The first flange cover 610 is fixedly connected to the first pipe section to enable rotation of the first pipe section, and the third flange cover is fixedly connected to the second pipe section to enable rotation of the second pipe section. It should be noted that the rotation direction of the first pipe section and the rotation direction of the second pipe section can be the same or different. As long as the sealing of the first inlet 310 and the first outlet 320 can be achieved, the rotation direction of the first pipe section and the second pipe section is not specifically limited.

[0050] Optionally, to improve the smoothness of the insertion of the first regulating pipe 510 into the inlet header 300, the gap between the outer wall of the first regulating pipe 510 and the inner wall of the inlet header 300 is 1.5mm-2.5mm. In this embodiment, the gap between the outer wall of the first regulating pipe 510 and the inner wall of the inlet header 300 is 2.0mm. In other embodiments, the gap between the outer wall of the first regulating pipe 510 and the inner wall of the inlet header 300 can be 1.5mm or 2.5mm, etc. It should be noted that, in order to avoid the problem of short circuit between the inner wall of the inlet header 300 and the outer wall of the first regulating pipe 510 due to an excessively large gap between the first regulating pipe 510 and the inlet header 300, the gap value should be minimized as much as possible while allowing rotation between the first regulating pipe 510 and the inlet header 300.

[0051] Optionally, when the length of the outlet header 400 is relatively long, the rotating assembly may further include a fourth flange cover. The fourth flange cover is fixedly connected to the other end of the second regulating pipe 520, and the end of the fourth flange cover and the other end of the outlet header 400 are detachably connected via a flange. The cooperation between the fourth flange cover and the second flange cover 620 improves the smoothness of the rotation of the second regulating pipe 520. In this embodiment, the fourth flange cover and the second regulating pipe 520 are welded together. In other embodiments, the fourth flange cover and the second regulating pipe 520 may be bonded together.

[0052] Optionally, the second flange cover 620 is circular, and its end is connected to one end of the outlet header 400 by multiple second bolts 621, which are evenly distributed along the circumferential mid-span of the second flange cover 620. When heat exchange with unsaturated media is performed, the second bolts 621 are removed to separate the second flange cover 620 from the outlet header 400. After rotating the second flange cover 620 by a certain angle (this angle is equal to the included angle between two adjacent second bolts 621, or is an integer multiple of the included angle between two adjacent second bolts 621), the positions of the third and fourth bolt holes are realigned, and the end of the second flange cover 620 is reconnected to the outlet header 400, thereby achieving the purpose of rotating the second regulating pipe 520. In this embodiment, the number of second bolts 621 is 12; in other embodiments, the number of second bolts 621 can be 4, 8, or 16, etc. In this embodiment, the rotation angle of the second flange cover 620 is 90 degrees. ° In other embodiments, the second flange cover 620 can rotate at an angle of 30 degrees. ° 60 ° Or 120 ° It should be noted that the rotation angle of the second flange cover 620 should not be 360 ​​degrees. ° This results in the second regulating pipe 520's wall failing to seal the second inlet 410 and the second outlet 420. In other embodiments, the second flange cover 620 can be magnetically fixed to one end of the outlet header 400, or fixed by a snap-fit ​​structure. It should be noted that, to improve the ease of rotation of the fourth flange cover, the fourth flange cover is connected to the other end of the outlet header 400 by 12 fourth bolts, which are evenly distributed along the circumferential mid-span of the fourth flange cover; further details will not be elaborated here.

[0053] Optionally, the second regulating pipe 520 is divided into a third pipe section and a fourth pipe section. The third pipe section is located at one end of the outlet header 400, and the second flange cover 620 is fixedly connected to the third pipe section, enabling the second flange cover 620 to drive the rotation of the third pipe section. The fourth pipe section is located at the other end of the outlet header 400, and the fourth flange cover is fixedly connected to the fourth pipe section, enabling the fourth flange cover to drive the rotation of the fourth pipe section. It should be noted that the rotation direction of the third pipe section and the rotation direction of the fourth pipe section can be the same or different. As long as the second inlet 410 and the second outlet 420 can be blocked, the rotation direction of the third pipe section and the fourth pipe section is not specifically limited.

[0054] Optionally, to improve the smoothness of the insertion of the second regulating pipe 520 into the outlet header 400, the gap between the outer wall of the second regulating pipe 520 and the inner wall of the outlet header 400 is 1.5mm-2.5mm. In this embodiment, the gap between the outer wall of the second regulating pipe 520 and the inner wall of the outlet header 400 is 2.0mm. In other embodiments, the gap between the outer wall of the second regulating pipe 520 and the inner wall of the outlet header 400 can be 1.5mm or 2.5mm, etc. It should be noted that, in order to avoid the problem of short circuit between the inner wall of the outlet header 400 and the outer wall of the second regulating pipe 520 due to an excessively large gap between the second regulating pipe 520 and the outlet header 400, the gap value should be minimized as much as possible while allowing for rotation between the second regulating pipe 520 and the outlet header 400.

[0055] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
