Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically a heat exchanger heater that allows multiple steam sources to participate in heat exchange simultaneously. Background Technology

[0002] Current heating network heaters all use a single steam source for heat exchange. However, in actual production, there are multiple steam sources. To fully utilize these sources, a separate heat exchanger is needed for each, increasing costs and requiring a large footprint. Therefore, in practice, much of the steam is not effectively utilized and is directly discharged, resulting in energy waste. Utility Model Content

[0003] To address the aforementioned issues, this application provides a heat exchanger for a network where multiple steam sources can simultaneously participate in heat exchange, thereby achieving efficient energy utilization.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A heat exchanger for a heat network that allows multiple steam sources to participate in heat exchange simultaneously includes a shell, a tube bundle, and a baffle plate. A first baffle plate extending axially is provided in the upper part of the shell side inside the shell.

[0006] The housing has several air source ports arranged along the axial direction on both sides of the first partition, and the several air source ports are used to connect to different air sources.

[0007] A second partition is installed between adjacent gas source ports located on the same side;

[0008] The first and second partitions together divide the upper space on the heater shell side into several expansion zones.

[0009] Furthermore, the lower end of the first partition is inserted into the tube bundle, and the lower end of the first partition is provided with a first slot for accommodating the baffle plate.

[0010] Furthermore, the baffle plate is provided with a second slot for accommodating the first partition plate. When the closed end of the first slot abuts against the closed end of the second slot, the distance from the upper side of the first partition plate to the axis of the tube bundle is less than or equal to the radius of the baffle plate.

[0011] The second baffle includes a fixed part disposed on the housing and a movable part disposed on the first baffle. The movable part is located between two adjacent baffles and is in contact with at least one baffle.

[0012] When the first partition is in the retracted state, the moving part of the second partition is located inside the outer edge of the baffle plate; when the first partition is in the extended state, the outer side of the moving part is in contact with the inner side of the fixed part.

[0013] The housing is provided with an installation tube, and a boss is provided on the inner side of the installation tube. An installation pressure plate is provided inside the installation tube above the boss. An installation hole is provided on the installation pressure plate, and an installation bolt is provided in the installation hole. A threaded hole that mates with the installation bolt is provided on the first partition plate.

[0014] Furthermore, an ear plate is provided at one end of the movable part facing the first partition plate, and the ear plate is fixedly connected to the first partition plate by a bolt assembly.

[0015] Furthermore, both the fixed part and the movable part have an arc-shaped structure.

[0016] Furthermore, a first sealing gasket is provided between the mounting plate and the boss.

[0017] Furthermore, a sealing plate is provided at the open end of the mounting tube, and the sealing plate is connected and fixed to the mounting cylinder by means of a flange connection. A second sealing gasket is provided between the sealing plate and the mounting tube.

[0018] Furthermore, an anti-impact plate is provided inside the housing below the gas source port.

[0019] Furthermore, the anti-impact plate has an arc-shaped structure.

[0020] Furthermore, a plurality of connecting posts are provided on the housing around the air source port, and the lower end of the connecting posts is fixedly connected to the anti-impact plate by screws.

[0021] The beneficial effects of this utility model are:

[0022] This application provides a heat network heater that allows multiple steam sources to participate in heat exchange simultaneously. By providing an expanded space at the top of the heater shell and installing a partition, steam at different pressures can enter the expanded, partitioned space. This solves the problem of existing heat network heaters having a single steam source and being unable to achieve simultaneous heat exchange from multiple steam sources. By addressing the issue of simultaneous heat exchange from multiple steam sources, energy can be fully utilized, thereby improving energy efficiency and achieving the goal of energy conservation and consumption reduction.

[0048] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings. The described embodiments are merely a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort should fall within the protection scope of this application.

[0049] For ease of description, the coordinate system is defined as follows: Figure 1 As shown, with left and right as the horizontal direction, front and back as the vertical direction, and up and down as the vertical direction, and according to... Figure 1 The coordinate system shown has the left end of the heater as the beginning and the right end as the end.

[0050] like Figure 1 , Figure 2 , Figure 9 and Figure 10 As shown, a heat exchanger for a heat network that allows multiple steam sources to participate in heat exchange simultaneously includes a shell 1, a tube bundle 2 disposed inside the shell 1, and multiple baffles 3 disposed along the axial direction on the tube bundle 2.

[0051] The housing 1 has a first partition 4 extending axially at the upper part of the housing side. The upper end of the first partition 4 abuts against the side wall of the housing 1, and the lower end of the first partition 4 is inserted into the tube bundle 2. The lower end of the first partition 4 is provided with a first slot 41 corresponding to the baffle 3. The baffle 3 is inserted into the corresponding first slot 41.

[0052] The first partition 4 divides the upper space on the shell side into two parts. For ease of description, according to... Figure 1 In the coordinate system shown, the space located in front of the first partition 4 is defined as the first space, and the space located behind the first partition 4 is defined as the second space.

[0053] The housing 1 is located on both sides of the first partition 4 (according to Figure 1 The coordinate system shown indicates that several air inlets 11 are respectively provided on the front and rear sides of the first partition 4, and the several air inlets 11 located on the same side are arranged in a straight line along the axial direction. A second partition 5 is provided between adjacent air inlets 11 located on the same side. The first partition 4 and the second partition 5 together divide the upper space on the heater shell side into several expansion zones.

[0054] In one specific implementation, the housing 1 in this embodiment has two air inlets 11 located on the front side of the first partition 4 and two air inlets 11 located on the rear side of the first partition 4. A second partition 5 is disposed within the first space between the two air inlets 11, dividing the first space into two expansion zones. Similarly, a second partition 5 is disposed within the second space between the two air inlets 11, dividing the second space into two expansion zones. That is, the first partition 4 and the second partition 5 together divide the upper space on the heater housing side into four expansion zones, and each expansion zone is provided with an air inlet 11 for introducing air.

[0055] By using the first partition 4 and the second partition 5 at the top of the heater shell side, the upper space of the heater shell side is divided into several expansion zones. In this way, different gas sources can enter the expansion zone through their respective gas source ports 11, expand their capacity and reduce their pressure to the working pressure of the equipment, and then mix and exchange heat together in the lower part of the heater shell side, realizing simultaneous heat exchange of multiple gas sources.

[0056] Furthermore, for ease of installation, such as Figure 11 and Figure 14 As shown, the baffle plate 3 is provided with a second slot 31 for accommodating the first partition plate 4. When the baffle plate 3 is inserted into the corresponding first slot 41 on the first partition plate 4, the first partition plate 4 is also inserted into the second slot 31 of the baffle plate 3, and the baffle plate 3 and the first partition plate 4 are in a cross-shaped insertion state. When the closed end of the first slot 41 abuts against the closed end of the second slot 31, the distance from the upper side of the first partition plate 4 to the axis of the tube bundle 2 is less than or equal to the radius of the baffle plate 3, that is, the upper side of the first partition plate 4 is located inside the second slot 31 or flush with the upper edge of the second slot 31.

[0057] like Figure 14 and Figure 15 As shown, the second baffle 5 includes a fixed part 51 and a movable part 52. The fixed part 51 has an arc-shaped structure arranged coaxially with the housing 1. The outer side of the fixed part 51 (with the side radially away from the axis of the housing 1 as the outer side) is fixedly connected to the side wall of the housing 1. The inner side of the fixed part 51 is greater than or equal to the diameter of the baffle 3. The movable part 52 is located between two adjacent baffles 3. Both ends of the movable part 52 along the axial direction are respectively attached to the baffle 3, and the end of the movable part 52 facing the first baffle 4 is fixedly connected to the first baffle 4. The outer side of the movable part 52 has an arc-shaped structure.

[0058] like Figure 14 As shown, when the first partition 4 is in the retracted state, the moving part 52 of the second partition 5 is located inside the outer edge of the baffle 3. Figure 6 and Figure 9 As shown, when the first partition 4 is in the extended state and the upper surface of the first partition 4 abuts against the side wall of the housing 1, the outer side of the moving part 52 is in contact with the inner side of the fixed part 51. The inner side of the moving part 52 is located inside the outer edge of the baffle 3. At this time, the fixed part 51 and the moving part 52 of the second partition 5 abut against each other to form a sealed whole. The second partition 5, as a sealed whole, is in contact with the baffle 3, which can achieve the effect of isolating the gas source. This prevents the various gas sources from mixing in the upper space of the heater shell side. Instead, they expand and depressurize in the expansion zone to reach the working pressure of the equipment. After expansion and depressurization, the gas sources will mix and exchange heat in the lower space of the heater shell side.

[0059] In one specific embodiment, the outer side of the fixing part 51 is fixedly connected to the side wall of the housing 1 by welding.

[0060] In one specific embodiment, the end of the movable part 52 facing the first partition 4 is fixedly connected to the first partition 4 in a detachable manner.

[0061] As one specific implementation method, such as Figure 13 As shown, in this embodiment, the movable part 52 has two ear plates 521 extending upward in the vertical direction at one end facing the first partition 4. The ear plates 521 are fixedly connected to the first partition 4 by bolt assembly.

[0062] In one specific embodiment, the moving part 52 described in this embodiment has an overall arc-shaped structure, that is, the inner side of the moving part 52 has an arc-shaped structure and is coaxial with the outer side of the moving part 52.

[0063] In one specific embodiment, the thickness of the fixing part 51 is less than the thickness of the moving part 52, and the fixing part 51 is located in the middle of the moving part 52.

[0064] like Figure 3 and Figure 4 As shown, a plurality of mounting tubes 12 communicating with the internal space of the housing 1 are provided on the housing 1 directly above the first partition 4. A ring-shaped boss 121 is provided on the inner side of each mounting tube 12. A mounting pressure plate 6 is provided inside the mounting tube 12 above the boss 121. The mounting pressure plate 6 has mounting holes, and mounting bolts 7 are installed in the mounting holes. A threaded hole 42 that mates with the mounting bolt 7 is provided on the upper surface of the first partition 4.

[0065] In one specific embodiment, the mounting plate 6 is circular and coaxially arranged with the mounting tube 12, and the mounting hole is located at the geometric center of the mounting plate 6.

[0066] In one specific embodiment, two mounting pipes 12 that communicate with the internal space of the housing 1 are provided on the housing 1 directly above the first partition 4.

[0067] Thus, during installation, the first partition 4 is first retracted, i.e. Figure 14 In the state shown, since the moving parts 52 of the first partition 4 and the second partition 5 are both located inside the outer edge of the baffle 3, the external dimensions of the entire tube bundle 2 section will not change, allowing it to be smoothly installed into the housing 1. When the tube bundle 2 section is inserted into the housing 1, as shown... Figure 16 As shown, a mounting plate 6 and a mounting bolt 7 are placed in each mounting tube 12, and the mounting bolt 7 is rotated to engage with the threaded hole 42 of the first partition plate 4. Then, the mounting bolts 7 in each mounting tube 12 are rotated simultaneously. At this time, under the pulling action of the mounting bolts 7, the first partition plate 4 and the moving part 52 of the second partition plate 5 fixed on the first partition plate 4 will move upward together until the upper end surface of the first partition plate 4 abuts against the side wall of the housing 1. At this time, the moving part 52 of the second partition plate 5 also abuts against the fixed part 51 of the second partition plate 5, completing the sealing connection.

[0068] Furthermore, in order to improve the sealing performance of the heater, a first sealing gasket (not shown in the figure) is provided between the mounting plate 6 and the boss 121.

[0069] Furthermore, in order to further improve the overall sealing performance of the heater, such as Figure 4 As shown, a flange 122 is provided at the upper end of the mounting pipe 12, and a sealing plate 8 is provided above the mounting pipe 12. The sealing plate 8 is connected and fixed to the flange 122 by a bolt assembly. A second sealing gasket (not shown in the figure) is provided between the sealing plate 8 and the flange 122.

[0070] Furthermore, to prevent the gas source entering the shell side from impacting the tube bundle 2, such as... Figure 5 and Figure 6 As shown, an anti-impact plate 9 is provided inside the housing 1 below the air source port 11.

[0071] Furthermore, the anti-impact plate 9 has an arc-shaped structure arranged coaxially with the housing 1, and the inner diameter of the anti-impact plate 9 is smaller than the diameter of the baffle plate 3. In this way, the anti-impact plate 9 can distribute the air source. After the air source enters the equipment, it can be gradually depressurized by the buffer of the anti-impact plate 9 and evenly distributed into the expansion area.

[0072] In one specific implementation, the anti-impact plate 9 described in this embodiment is fixedly connected to the housing 1 in a detachable manner.

[0073] As one specific implementation method, such as Figure 7 , Figure 8 and Figure 15 As shown, in this embodiment, a plurality of connecting posts 13 are arranged around the air source port 11 on the housing 1. The upper end of the connecting post 13 is fixedly connected to the housing 1 by welding, and the lower end of the connecting post 13 is fixedly connected to the anti-impact plate 9 by screws.

[0074] Other embodiments obtained by those skilled in the art based on the embodiments provided in this application by combining, splitting, or reorganizing the embodiments of this application do not exceed the protection scope of this application.

[0075] The above detailed embodiments have provided a detailed explanation of the purpose, technical solutions, and beneficial effects of the embodiments of this application. The above are merely specific embodiments of the embodiments of this application and are not intended to limit the protection scope of the embodiments of this application. That is, any modifications, equivalent substitutions, improvements, etc., made on the basis of the embodiments of this application should be included within the protection scope of the embodiments of this application.
