Description

Technical Field

[0001] This application relates to the field of reactor condensation system technology, and more specifically to a heat exchange component for a reactor. Background Technology

[0002] Some reactors include condensation devices for treating high-temperature steam or waste gas. These typically consist of multiple rows of condenser tubes, with a continuous flow of cooling liquid into them. The cooling liquid flowing through the tubes cools the high-temperature steam outside, utilizing its thermal energy and reducing energy waste, thus improving the overall system's energy efficiency. However, existing technologies suffer from low heat exchange efficiency, and the condenser tubes cannot adequately exchange the temperature of the high-temperature steam. Summary of the Invention

[0003] This utility model provides a heat exchange component for a reactor to solve the problems of low heat exchange efficiency and inability of condenser tubes to fully exchange the temperature of high-temperature steam in the prior art.

[0004] This utility model discloses a heat exchange assembly for a reactor, including a heat exchange component and a mounting bracket for fixing the heat exchange component. The heat exchange component includes heat exchange tubes and heat exchange plates arranged alternately, and the heat exchange tubes and multiple heat exchange plates are connected in parallel or in series.

[0005] In this design, by setting alternating heat exchange tubes and heat exchange plates in the high-temperature rich area at the top of the reactor, the heat exchange surface area in this area is increased, thereby improving the heat exchange efficiency.

[0006] In some embodiments, the system further includes a water distribution pipe and a water outlet pipe, wherein the water distribution pipe is simultaneously connected to the water inlet end of a plurality of heat exchange plates, and the water outlet pipe is simultaneously connected to the water outlet end of a plurality of heat exchange plates; the heat exchange tube is wound around the water distribution pipe and the water outlet pipe.

[0007] In this design, the heat exchange tubes and heat exchange plates are connected in parallel, and adjacent heat exchange plates are also connected in parallel, so that the two heat exchange structures are independent of each other. Under this structure, considering that the heat exchange efficiency of different heat exchange structures is different, their independence ensures that their heat exchange rates do not affect each other, which is conducive to improving the overall heat exchange efficiency.

[0008] In some embodiments, the mounting bracket includes a plurality of longitudinal supports, which are respectively connected to the water distribution pipe and the water outlet pipe via scaffolding.

[0009] In this design, the aforementioned heat exchange tubes, heat exchange plates, water distribution pipes, and water outlet pipes are fixed at a certain height using a longitudinal support frame. This is secured with scaffolding, and then the longitudinal support frame is connected to the internal structure of the reactor. Preferably, a tubular longitudinal support frame is chosen for easy connection to the circular water distribution pipes and water outlet pipes.

[0010] In some embodiments, a tube support is provided between the heat exchange tube and the heat exchange plate.

[0011] In this design, in order to improve the stability of the heat exchange tubes and heat exchange plates, tube supports are installed at positions close to each other to connect the heat exchange tubes and heat exchange plates to each other.

[0012] In some embodiments, the water distribution pipe is connected to the heat exchange pipe, the heat exchange pipe is connected to the heat exchange plate at both ends, and the water outlet pipe is connected to the heat exchange pipe at the tail end.

[0013] In this design, the heat exchange tubes and heat exchange plates are connected end to end, i.e., they are connected in series. Although this structure increases the tube length for heat exchange, it allows the water inlet of the water distribution pipe to be placed in the area with the highest temperature, forming a gradient distribution opposite to the temperature inside the reactor, which is beneficial to improving the overall heat exchange efficiency.

[0014] In some embodiments, multiple sets of second heat exchange plates are also provided between the longitudinal supports, and the second heat exchange plates are connected to the water distribution pipe through a two-way valve.

[0015] In this embodiment, by installing a second heat exchange plate along the longitudinal direction of the reactor tower, some of the heat of the high-temperature steam is exchanged with the second heat exchange plate as it moves towards the top of the tower, thereby further improving the heat exchange capacity of the heat exchange system.

[0016] In some embodiments, the heat exchange plate has an array of protrusions on its two heat exchange surfaces.

[0017] In this embodiment, the protrusions on the surface of the heat exchange plate increase the surface area of ​​contact between the high-temperature steam and the heat exchange plate, which helps to improve the heat exchange efficiency of the heat exchange plate.

[0018] In some embodiments, the heat exchange plate includes Z-shaped fins.

[0019] In this embodiment, fins are provided inside the heat exchange plate to make the cooling liquid distribution inside the heat exchange plate more uniform, while increasing the temperature exchange surface area inside the heat exchange tube.

[0020] The beneficial effects of this utility model are as follows: This utility model provides a heat exchange component for a reactor. By setting alternating heat exchange tubes and heat exchange plates in the high-temperature rich area at the top of the reactor, the heat exchange surface area in this area is increased, thereby improving the heat exchange efficiency.

[0023] The technical solutions in the embodiments of the application will now be clearly and completely described with reference to the accompanying drawings. Furthermore, the phrases "in one embodiment" or "in one embodiment" appearing throughout this specification do not necessarily refer to the same embodiment. Moreover, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0024] Some reactors include condensation devices for treating high-temperature steam or waste gas. These typically consist of multiple rows of condenser tubes, with a continuous flow of cooling liquid into them. The cooling liquid flowing within the tubes cools the high-temperature steam outside, utilizing the heat energy within the steam, reducing energy waste, and improving the overall system's energy efficiency. However, existing technologies suffer from low heat exchange efficiency, and the condenser tubes cannot adequately exchange the temperature of the high-temperature steam. Therefore, this invention provides a heat exchange component for reactors, which will be described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a heat exchange assembly for a reactor, including a heat exchange assembly 1 and a mounting bracket for fixing the heat exchange assembly 1. The heat exchange assembly 1 includes heat exchange tubes 11 and heat exchange plates 12 arranged alternately, and the heat exchange tubes 11 and multiple heat exchange plates 12 are connected in parallel or in series.

[0026] Generally, the heat exchange efficiency of the condenser in a reactor is closely related to the coverage rate of the condenser tubes and the heat exchange surface area in the high-temperature steam-rich area. Increasing the number of condenser tubes, i.e., increasing the coverage rate of condenser tubes in the steam-rich area, can improve the heat exchange efficiency in the reactor. In this design, by setting alternating heat exchange tubes 11 and heat exchange plates 12 in the high-temperature steam-rich area at the top of the reactor, the heat exchange surface area in this area is increased, thereby improving the heat exchange efficiency.

[0027] It should be noted that, based on the alternating arrangement of the heat exchange tubes 11 and heat exchange plates 12, a water distribution pipe 13 and a water outlet pipe 14 are also included. The water distribution pipe 13 is simultaneously connected to the water inlet end of multiple heat exchange plates 12, and the water outlet pipe 14 is simultaneously connected to the water outlet end of multiple heat exchange plates 12. The heat exchange tubes 11 are wound around the water distribution pipe 13 and the water outlet pipe 14.

[0028] like Figure 1 As shown, the heat exchange tube 11 is connected in parallel with multiple heat exchange plates 12. Figure 1 (The direction of cooling water flow in heat exchange tube 11 is indicated by black arrows, and the direction of cooling water flow in heat exchange plate 12 is indicated by dashed arrows.) In this design, the heat exchange tubes 11 and heat exchange plates 12 are connected in parallel, and adjacent heat exchange plates 12 are also connected in parallel. External cooling water enters through the distribution pipe 13, then flows through multiple parallel heat exchange plates 12, partially passing through the heat exchange tubes 11, and finally exits through the outlet pipe 14. During this flow, heat exchange occurs with external hot steam. It should be noted that in this invention, the heat exchange tubes 11 can be multiple and independent, or a single heat exchange tube 11 can be coiled or looped in the heat exchange space to form a heat exchange structure covering a certain surface area.

[0029] The aforementioned parallel heat exchange structures, because different heat exchange structures have different heat exchange efficiencies and are independent of each other, ensure that their heat exchange rates do not affect each other, which is conducive to improving the overall heat exchange efficiency.

[0030] In some embodiments, the mounting bracket for fixing and supporting the heat exchange structure consisting of heat exchange tube 11 and heat exchange plate 12 includes several longitudinal brackets, which are respectively connected to water distribution pipe 13 and water outlet pipe 14 via scaffolding.

[0031] In this embodiment, the aforementioned heat exchange tube 11, heat exchange plate 12, water distribution pipe 13, and water outlet pipe 14 are fixed at a certain height using a longitudinal support. This is secured with scaffolding, and then the longitudinal support is connected to the internal structure of the reactor. Preferably, a tubular longitudinal support is chosen for easy connection to the circular water distribution pipe 13 and water outlet pipe 14. The scaffolding in this embodiment is not a special structure and its detailed structural design is not provided; the scaffolding structure used in actual engineering projects is referenced.

[0032] In addition, a pipe support 2 is provided between the aforementioned heat exchange tube 11 and heat exchange plate 12. This design aims to improve the stability of the heat exchange tube 11 and heat exchange plate 12. Specifically, the pipe support 2 is placed at a position close to each other to connect the heat exchange tube 11 and heat exchange plate 12. The pipe support 2 includes a support rod and pipe clamps mounted on the support rod. The pipe clamps are C-shaped and a limiting plate slightly larger than the width of the heat exchange plate 12, which can fix the heat exchange tube 11 and heat exchange plate 12 to the support rod. Both ends of the support rod are detachably connected to a longitudinal support. This detachable connection structure is the same as the aforementioned scaffolding structure.

[0033] The heat exchange tube 11 is connected in series with multiple heat exchange plates 12: Specifically, the aforementioned water distribution pipe 13 is connected to the heat exchange pipe 11, the heat exchange pipe 11 is connected to the heat exchange plate 12 at both ends, and the water outlet pipe 14 is connected to the heat exchange pipe 11 at the end.

[0034] In this design, the heat exchange tubes 11 and the heat exchange plates 12 are connected end to end, i.e., they are connected in series. Although this structure increases the tube length for heat exchange, it allows the water inlet of the water distribution pipe 13 to be placed in the area with the highest temperature, forming a gradient distribution opposite to the temperature inside the reactor, which is beneficial to improving the overall heat exchange efficiency.

[0035] In addition to the aforementioned series connection method, other methods include... Figure 2 The series connection configuration shown can be configured such that multiple heat exchange plates 12 are connected in parallel and multiple heat exchange tubes 11 are connected in series; or, multiple heat exchange plates 12 are connected in series and multiple heat exchange tubes 11 are connected in parallel. Figure 2 In the diagram, black arrows indicate the direction of cooling water flow inside heat exchange tube 11, and dashed arrows indicate the direction of cooling water flow inside heat exchange plate 12.

[0036] In other embodiments, multiple sets of second heat exchange plates 15 are provided between the aforementioned longitudinal supports, and the second heat exchange plates 15 are connected to the water distribution pipe 13 through a two-way valve.

[0037] like Figure 3 As shown, in this embodiment, by installing a second heat exchange plate 15 along the direction of the reactor tower, some of the heat of the high-temperature steam is exchanged with the second heat exchange plate 15 during its movement towards the top of the tower, thereby further improving the heat exchange capacity of the heat exchange system.

[0038] It should be noted that the heat exchange plates 12 and 15 in the aforementioned embodiments are provided with arrayed protrusions 121 on their two heat exchange surfaces. These protrusions 121 increase the surface area of ​​contact between the high-temperature steam and the heat exchange plates 12 and 15, thus helping to improve the heat exchange efficiency of the heat exchange plates 12 and 15. Furthermore, both the heat exchange plates 12 and 15 contain Z-shaped fins 122. Figure 4As shown, fins are provided in the heat exchange plate 12 and the second heat exchange plate 15 to make the cooling liquid distribution in the heat exchange plate 12 and the second heat exchange plate 15 more uniform, and at the same time increase the internal temperature exchange surface area of ​​the heat exchange plate 12 and the second heat exchange plate 15.

[0039] In summary, this utility model provides a heat exchange assembly for a reactor, comprising a heat exchange assembly 1 and a mounting bracket for fixing the heat exchange assembly 1. The heat exchange assembly 1 is characterized in that it includes alternately arranged heat exchange tubes 11 and heat exchange plates 12, wherein the heat exchange tubes 11 and multiple heat exchange plates 12 are connected in parallel or in series. This utility model increases the heat exchange surface area and improves heat exchange efficiency by setting alternately arranged heat exchange tubes 11 and heat exchange plates 12 in the high-temperature rich region at the top of the reactor.

[0040] The above embodiments merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
