Description

Technical Field

[0001] This utility model belongs to the technical field of tower heat exchangers, specifically a high-efficiency tower heat exchanger. Background Technology

[0002] A heat exchanger is an energy-saving device that facilitates heat transfer between two or more fluids at different temperatures. It transfers heat from a higher-temperature fluid to a lower-temperature fluid, bringing the fluid temperature to the specified parameters to meet process requirements. It is also one of the key devices for improving energy efficiency. Heat exchangers play a vital role in chemical, petroleum, power, food, and many other industrial production processes. In chemical production, heat exchangers are widely used as heaters, coolers, condensers, evaporators, and reboilers.

[0003] A search revealed that patent publication number CN219265058U discloses a tower-type high-efficiency heat exchanger, comprising a heat exchange shell. An upper tube sheet and a lower tube sheet are fixed to the upper and lower ends of the heat exchange shell, respectively. Multiple heat exchange tubes are fixedly connected between the upper and lower tube sheets, and an inner tube passes through each heat exchange tube. This invention comprises a heat exchange shell, heat exchange tubes, an inner tube, a fluid inlet assembly, and a fluid outlet assembly. The material to be heat-exchanged enters the interlayer between the inner tube and the heat exchange tubes. Simultaneously, fluid enters the interior of the heat exchange shell and the interior of the inner tubes through the fluid inlet assembly. The fluid inside the heat exchange shell performs the first heat transfer to the material to be heat-exchanged in the heat exchange tubes, and the fluid inside the inner tubes performs the second heat transfer to the material to be heat-exchanged in the heat exchange tubes. This simultaneous heat transfer between the inside and outside of the heat exchange tubes improves the heat transfer efficiency of the heat exchanger. The fluid finally flows out through the fluid outlet assembly, achieving continuous fluid flow and efficient heat exchange for the material inside the heat exchange tubes.

[0004] In practical use, when two fluids flow separately and exchange heat in existing tower-type high-efficiency heat exchangers, the flow of the two fluids during heat exchange is relatively straight. At this time, the heat exchange time between the two fluids is short and the contact area between the two fluids is small, resulting in poor heat exchange effect between the two fluids. Therefore, a tower-type high-efficiency heat exchanger is designed. Utility Model Content

[0005] In view of the defects or deficiencies of tower-type high-efficiency heat exchangers, the purpose of this utility model is to provide a tower-type high-efficiency heat exchanger that not only increases the heat exchange time when two fluids flow separately, but also increases the contact area for heat exchange between the two fluids, thereby effectively improving the heat exchange efficiency between the two fluids.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a tower-type high-efficiency heat exchanger, including a tower body. A top cover and a bottom cover are respectively installed at the top and bottom of the tower body. Hollow partitions are installed above and below the inner wall of the tower body. A hollow guide plate is arranged between two hollow partitions. The hollow guide plate is installed on the inner wall of the tower body. The hollow guide plates are connected to each other in pairs through a connecting component. Both hollow partitions are connected to the hollow guide plate through the connecting component.

[0008] Preferably, the connecting component is composed of two hollow connecting plates and a spring-shaped connecting tube, with the two hollow connecting plates disposed at both ends of the spring-shaped connecting tube, and the interior of the spring-shaped connecting tube being connected to the interior of the hollow connecting plates.

[0009] Preferably, a first flow pipe is provided between the two side surfaces of the hollow partition. The first flow pipe is arranged in a ring array. Both ends of the first flow pipe penetrate the two side surfaces of the hollow partition, and the connection between the two ends of the first flow pipe and the two side surfaces of the hollow partition is sealed by welding.

[0010] Preferably, one end of the first flow tube is connected to the hollow guide plate on the connecting component, the interior of the first flow tube is connected to the interior of the hollow guide plate, and the connection between the first flow tube and the hollow guide plate is sealed by welding.

[0011] Preferably, a second flow pipe is provided between the two side surfaces of the hollow guide plate. The second flow pipe is arranged in a ring array. Both ends of the second flow pipe penetrate the two side surfaces of the hollow guide plate, and the connection between the two ends of the second flow pipe and the two side surfaces of the hollow guide plate is sealed by welding.

[0012] Preferably, the two ends of the second flow tube are respectively connected to two hollow guide plates on the connecting component, the interior of the second flow tube is connected to the interior of the hollow guide plate, and the connection between the second flow tube and the hollow guide plate is sealed by welding.

[0015] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0016] 1. In this utility model, through a series of structural arrangements, when the worker performs heat exchange between two fluids, during the process of the worker inputting one fluid from the first input pipe and discharging it from the first output pipe, the fluid flows in an S-shape, increasing the fluid's flow time. During the process of the worker inputting the other fluid from the second input pipe and discharging it from the second output pipe, the other fluid flows in a spiral shape when it reaches the spring-shaped connecting pipe. During the process of the other fluid passing through multiple spring-shaped connecting pipes in sequence, the flow time of the other fluid is increased.

[0017] 2. In this utility model, the hollow partition, the connecting component and the hollow guide plate are arranged in combination.

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0037] like Figure 1-7 As shown, a tower-type high-efficiency heat exchanger includes a tower body 100. A top cover 200 and a bottom cover 300 are respectively installed at the top and bottom of the tower body 100. Hollow baffles 400 are installed above and below the circumferential inner wall of the tower body 100. A hollow guide plate 600 is arranged between two hollow baffles 400. The hollow guide plates 600 are installed on the circumferential inner wall of the tower body 100. The hollow guide plates 600 are connected to each other in pairs by a connecting component 500. Both hollow baffles 400 are connected to the hollow guide plates 600 by the connecting component 500. The two hollow baffles 400 can separate the internal cavity between the tower body 100, the top cover 200 and the bottom cover 300.

[0038] The connecting component 500 is composed of two hollow connecting plates 510 and a spring-shaped connecting tube 520. The two hollow connecting plates 510 are located at both ends of the spring-shaped connecting tube 520, and the interior of the spring-shaped connecting tube 520 is connected to the interior of the hollow connecting plates 510. When the fluid flows into the spring-shaped connecting tube 520, the fluid flows in a spiral shape, which increases the fluid flow time and thus increases the fluid heat exchange time. The overall surface area of ​​the spring-shaped connecting tube 520 is larger than that of the straight connecting tube, thereby increasing the contact area for fluid heat exchange.

[0039] A first flow pipe 410 is provided between the two side surfaces of the hollow partition 400. The first flow pipe 410 is arranged in a ring array. Both ends of the first flow pipe 410 penetrate the two side surfaces of the hollow partition 400 respectively, and the connection between the two ends of the first flow pipe 410 and the two side surfaces of the hollow partition 400 is sealed by welding. Because the connection between the two ends of the first flow pipe 410 and the two side surfaces of the hollow partition 400 is sealed by welding, the connection between the first flow pipe 410 and the hollow partition 400 can be sealed.

[0040] One end of the first flow pipe 410 is connected to the hollow guide plate 600 on the connecting component 500. The interior of the first flow pipe 410 is connected to the interior of the hollow guide plate 600, and the connection between the first flow pipe 410 and the hollow guide plate 600 is sealed by welding. Because the connection between the first flow pipe 410 and the hollow guide plate 600 is sealed by welding, the connection between the first flow pipe 410 and the hollow guide plate 600 can be sealed.

[0041] A second flow pipe 620 is provided between the two side surfaces of the hollow guide plate 600. The second flow pipes 620 are arranged in a ring array. Both ends of the second flow pipe 620 penetrate the two side surfaces of the hollow guide plate 600 respectively, and the connection between the two ends of the second flow pipe 620 and the two side surfaces of the hollow guide plate 600 is sealed by welding. Because the connection between the two ends of the second flow pipe 620 and the two side surfaces of the hollow guide plate 600 is sealed by welding, the connection between the second flow pipe 620 and the hollow guide plate 600 can be sealed.

[0042] The two ends of the second flow pipe 620 are respectively connected to the two hollow guide plates 600 on the connecting component 500. The interior of the second flow pipe 620 is connected to the interior of the hollow guide plate 600, and the connection between the second flow pipe 620 and the hollow guide plate 600 is sealed by welding. Because the connection between the second flow pipe 620 and the hollow guide plate 600 is sealed by welding, the connection between the second flow pipe 620 and the hollow guide plate 600 can be sealed.

[0043] An input groove 610 is provided on one side of the upper surface of the hollow guide plate 600, and the input groove 610 is connected to the interior of the hollow guide plate 600. An output groove 630 is provided on the other side of the lower surface of the hollow guide plate 600, and the output groove 630 is connected to the interior of the hollow guide plate 600. Fluid flows from the input groove 610 to the interior of the hollow guide plate 600 and is discharged from the output groove 630.

[0044] The connection between the spring-shaped connecting tube 520 and the hollow connecting plate 510 is sealed by welding. Because the connection between the spring-shaped connecting tube 520 and the hollow connecting plate 510 is sealed by welding, the connection between the spring-shaped connecting tube 520 and the hollow connecting plate 510 can be sealed.

[0045] A first input pipe 120 is provided on the upper side of one side of the outer wall of the tower body 100, and a first output pipe 110 is provided on the lower side of one side of the outer wall of the tower body 100. The interiors of the first input pipe 120 and the first output pipe 110 are connected to the interior of the tower body 100. A second input pipe 210 is provided on one side of the outer wall of the top cover 200, and the interior of the second input pipe 210 is connected to the interior of the top cover 200. A second output pipe 310 is provided on one side of the outer wall of the bottom cover 300, and the interior of the bottom cover 300 is connected to the interior of the second output pipe 310.

[0046] Working principle: When heat exchange occurs between two fluids, one fluid is introduced into the tower body 100 through the first inlet pipe 120. The fluid flows from the inlet slot 610 on the hollow guide plate 600 into the interior of the hollow guide plate 600. The fluid inside the hollow guide plate 600 is discharged from the outlet slot 630. After passing through multiple hollow guide plates 600, the fluid is discharged from the first outlet pipe 110. During the process of the fluid entering through the first inlet pipe 120 and exiting through the first outlet pipe 110, the fluid exhibits an S-shaped flow pattern. The movement increases the fluid flow time. When the operator introduces another fluid into the top cover 200 through the second inlet pipe 210, the fluid flows from the first flow pipe 410 on the hollow partition 400 above the tower body 100 into the connecting component 500. The fluid in the connecting component 500 flows into the second flow pipe 620 on the hollow guide plate 600. The fluid in the second flow pipe 620 flows into the connecting component 500 again. After flowing through multiple second flow pipes 620, the fluid finally flows into the tower body through the second flow pipe 620. The fluid in the first flow pipe 410 on the hollow partition 400 below the tower body 100 flows into the interior of the bottom cover 300. The fluid in the bottom cover 300 is discharged from the second output pipe 310. Thus, during the process of another fluid entering from the second input pipe 210 and exiting from the second output pipe 310, the other fluid flows in a spiral shape when it reaches the spring-shaped connecting pipe 520. The other fluid passes through multiple spring-shaped connecting pipes 520 in sequence, increasing the fluid flow time. 400, the connecting component 500, and the hollow guide plate 600 are all made of thermally conductive metal material. One fluid flows through multiple hollow guide plates 600 in an S-shaped flow, while the other fluid flows through the first flow pipe 410, the second flow pipe 620, and the connecting component 500. The heat exchange contact area between the two fluids is increased. Therefore, as can be seen from the above, this utility model not only increases the heat exchange time when the two fluids flow separately, but also increases the heat exchange contact area between the two fluids, thereby effectively improving the heat exchange efficiency between the two fluids.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the invention. For those skilled in the art, various modifications and variations can be made to this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
