[0035] See also Figure 1-Figure 8 .

[0036] Some embodiments of the present application disclose a modular heat exchange device that can be assembled and disassembled, which is an annular cavity located between the discharge pipe shield and the civil structure. The modular heat exchange device that can be assembled and disassembled includes a sealed pressure-bearing shell 1 and a heat exchange component 2. The sealed pressure-bearing shell 1 has at least two arc-shaped shells, and a heat exchange component 2 is respectively arranged in each arc-shaped shell. The arc-shaped shell and the heat exchange component 2 form a modular heat exchange structure, and the modular heat exchange structure is detachably connected to the civil structure through the arc-shaped shell.

[0037] At least two arc-shaped shells are spliced ​​together to form an annular sealed pressure-bearing shell 1 that matches the shape of the annular cavity, so as to cool the circumference of the discharge pipe shield.

[0038] The assembleable and disassembled modular heat exchange device disclosed in the present solution has a plurality of modular heat exchange structures composed of an arc-shaped shell and a heat exchange assembly 2. The modular heat exchange structures are assembled in the circumferential direction of the discharge pipe shield as needed. The volume of a single modular heat exchange structure is small, and the heat exchange structure is detachably connected to the civil structure. When a single modular heat exchange structure fails, the failed modular heat exchange structure can be individually disassembled and repaired, thereby solving the problem in the related art that the heat exchange tubes of the heat exchange device cannot be repaired and replaced.

[0039] In this solution, the inner ring of the sealed pressure-bearing shell 1 is close to the discharge pipe shield, and the heat exchange component 2 is arranged close to the inner ring. The cold energy of the heat exchange component 2 is transferred to the discharge pipe shield through the inner ring to cool the discharge pipe shield.

[0040] The shape of the sealed pressure-bearing shell 1 is adapted to the shape of the annular inner cavity, and the heat exchange components 2 are evenly distributed in the circumferential direction of the sealed pressure-bearing shell 1 to cool down various positions in the circumferential direction of the discharge pipe shielding.

[0041] The assembleable and disassembled modular heat exchange device disclosed in the present scheme is not limited to cooling the discharge pipe shield, but can also be applied to other tubular structures that require heat exchange, wherein the heat exchange can be heating or cooling. When the tubular structure needs to be heated, the assembleable and disassembled modular heat exchange device transfers heat to the tubular structure; when the tubular structure needs to be cooled, the assembleable and disassembled modular heat exchange device transfers cold to the tubular structure.

[0042] The modular heat exchange device that can be assembled and disassembled disclosed in the present solution can be filled with heat exchange medium only in the heat exchange component, or can be filled with heat exchange medium in the sealed pressure-bearing shell 1 at the same time. In the embodiment where the heat exchange medium is filled in both the sealed pressure-bearing shell 1 and the heat exchange component, the modular heat exchange device that can be assembled and disassembled can realize two-pass heat exchange, and the heat exchange medium in the sealed pressure-bearing shell 1 needs to flow, and the heat exchange medium in the sealed pressure-bearing shell 1 cools down the heat exchange component on the one hand, and cools down the civil structure on the other hand.

[0043] In this scheme, the heat exchange component 2 is located in the sealed pressure-bearing shell 1. When the heat exchange component 2 leaks, the heat exchange medium of the heat exchange component 2 will enter the sealed pressure-bearing shell 1 with a sealed pressure-bearing function, preventing the heat exchange medium from leaking out of the assembleable and detachable modular heat exchange device, thereby improving the reliability of the assembleable and detachable modular heat exchange device. The impact of the leakage of the heat exchange component 2 can be ignored, and will not affect the assembleable and detachable modular heat exchange device to continue the heat exchange operation, and the impact on the heat exchange capacity of the assembleable and detachable modular heat exchange device is small.

[0044] Optionally, a detection device is provided in the sealed pressure-bearing shell 1 for detecting the liquid pressure and / or liquid level in the sealed pressure-bearing shell 1 to determine whether the heat exchange component 2 is leaking.

[0045] The sealed pressure-bearing shell 1 may be an annular shell, the shape of which is the same as the shape of the annular cavity, and the sealed pressure-bearing shell 1 is sleeved on the discharge pipe shield from bottom to top.

[0046] The sealed pressure-bearing shell 1 may be an arc-shaped shell, and the number of the arc-shaped shells is at least two. In the embodiment where the sealed pressure-bearing shell 1 has two arc-shaped shells, the arc of a single arc-shaped shell is 180°, and the two arc-shaped shells are spliced ​​to form an annular shell; in the embodiment where the sealed pressure-bearing shell 1 has three or more arc-shaped shells, the three or more arc-shaped shells are spliced ​​to form an annular shell, and in this case, the arcs of the multiple arc-shaped shells may be the same or different, and the heat exchange components 2 in the multiple arc-shaped shells may be the same or different.

[0047] In the embodiment in which the sealed pressure-bearing shell 1 is formed by combining two or more arc-shaped shells, each arc-shaped shell and the heat exchange component 2 form an independent heat exchange structure. The heat exchange structures have no connection relationship in realizing the heat exchange function. The heat exchange work between them is independent of each other and does not affect each other. At least two heat exchange structures are combined to jointly act on the shielding of the discharge pipe and independently play the role of heat exchange.

[0048] like Figure 3 , Figure 5 , Figure 7 and Figure 8 As shown, the sealed pressure-bearing shell 1 includes two semicircular arc shells, the two arc shells form a circular ring, and there are two heat exchange structures in the circumferential direction of the discharge pipe shield.

[0049] In an embodiment in which the sealed pressure-bearing shell 1 is formed by combining two or more arc-shaped shells, adjacent arc-shaped shells are connected in a detachable manner, and a single arc-shaped shell can be detachably connected to the civil structure, so that the sealed pressure-bearing shell 1 that needs to be repaired can be replaced as needed.

[0050] In the embodiment in which the sealed pressure-bearing shell 1 is formed by combining two or more arc-shaped shells, during installation, one of the arc-shaped shells is first connected to the civil engineering structure, and then the arc-shaped shell adjacent to it is connected to the civil engineering structure, and then the two adjacent arc-shaped shells are connected, and so on, to achieve the fixation of all the arc-shaped shells on the civil engineering structure and the connection of two adjacent arc-shaped shells; during disassembly, one of the arc-shaped shells is first disassembled from the civil engineering structure, and then the arc-shaped shell adjacent to it is disassembled from the civil engineering structure, and then the two adjacent arc-shaped shells are disassembled, and so on, to achieve the disassembly of all the arc-shaped shells from the civil engineering structure and the disassembly of two adjacent arc-shaped shells.

[0051] The heat exchange assembly 2 has a liquid inlet pipe 21 and a liquid outlet pipe 22. The liquid inlet pipe 21 and the liquid outlet pipe 22 are fully or partially extended out of the sealed pressure-bearing shell 1 to facilitate connection with external equipment.

[0052] There are many ways to detachably connect two adjacent sealed pressure-bearing shells 1 .

[0053] In some embodiments, at least one end surface of the arc-shaped shell in the axial direction is provided with a buckle 11 and a hook 12, the buckle 11 and the hook 12 are respectively located at the first end and the second end of the arc-shaped shell, and two adjacent arc-shaped shells are detachably connected through the buckle 11 and the hook 12. Figure 6 As shown, the buckle 11 is Z-shaped, and the Z-shaped buckle 11 includes a first horizontal plate, a second horizontal plate and an inclined plate, the inclined plate is located between the first horizontal plate and the second horizontal plate, the first horizontal plate is fixedly connected to the end face of the arc-shaped shell, and a rectangular opening that cooperates with the hook 12 is opened on the second horizontal plate, and the hook 12 includes a third horizontal plate and an arc plate, the third horizontal plate is fixedly connected to the end face of the arc-shaped shell, and the arc plate is engaged with the rectangular opening of the second horizontal plate. After the arc plate slides into the rectangular opening of the second horizontal plate, the two adjacent arc-shaped shells are connected by a snap connection. When disassembling, the arc-shaped shell is provided with one end of the hook 12 in the direction away from the second horizontal plate, so that the hook 12 slides out of the rectangular opening of the second horizontal plate, and the two adjacent arc-shaped shells are separated.

[0054] The hook 12 and the buckle 11 are not limited to the above-mentioned structural forms, and may also be in other forms, which are not specifically limited here.

[0055] In some embodiments, the arc-shaped shell is connected by a connecting plate and bolts. Specifically, a connecting plate is provided on the side wall of the arc-shaped shell, and a mounting hole is provided on the connecting plate. After the side walls of two adjacent arc-shaped shells are fitted together, the connecting plates of the two adjacent arc-shaped shells overlap and the mounting holes are positioned relative to each other. The bolts are inserted into the mounting holes and are locked on the connecting plates by nuts.

[0056] In some embodiments, two adjacent arc-shaped shells are hingedly connected. After the two adjacent arc-shaped shells are hingedly connected, each of the two adjacent arc-shaped shells has a certain degree of freedom of movement after being connected, that is, they can be adjusted according to the shielding shape of the discharge pipe, and can also be opened at a certain angle for processing according to maintenance requirements.

[0057] The detachable connection method of two adjacent arc-shaped shells is not limited to the above embodiment, and other connection methods, such as magnetic attraction, etc., can also be used, which is not specifically limited here.

[0058] After two adjacent arc-shaped shells are detachably connected, the sealed pressure-bearing shell 1 composed of multiple arc-shaped shells may have relative movement in the circumferential direction, affecting the stability of the shielded connection between the assembleable and detachable modular heat exchange device and the discharge pipe.

[0059] In order to solve the above problems, the assembleable and disassembled modular heat exchange device disclosed in the present scheme also includes a clamp 13, which is arranged around the sealed pressure-bearing shell 1 composed of multiple arc-shaped shells, and is used to apply a circumferential tightening force to the sealed pressure-bearing shell 1 composed of multiple arc-shaped shells to prevent the multiple arc-shaped shells of the sealed pressure-bearing shell 1 from circumferential diffusion.

[0060] In order to prevent the clamp 13 from moving along the axis of the sealed pressure-bearing housing 1, a limiting structure is provided on the outer wall of the outer ring of the sealed pressure-bearing housing 1 to limit the clamp 13 along the axis of the sealed pressure-bearing housing 1. In some embodiments, the limiting structure is a limiting groove provided on the outer wall of the outer ring of the sealed pressure-bearing housing 1; in other embodiments, the limiting structure is a limiting buckle provided on the outer wall of the outer ring of the sealed pressure-bearing housing 1.

[0061] In some embodiments, the clamp 13 is a flat steel with a rectangular cross-section, and a through hole is provided at the end of the flat steel. After the clamp 13 is surrounded on the sealed pressure-bearing shell 1, bolts pass through the through holes at both ends of the flat steel to lock the ends of the flat steel.

[0062] In some embodiments, a buckle 11 and a hook 12 are provided on one end surface of the arc-shaped shell, and a clamp 13 is provided in the middle of the sealed pressure-bearing shell 1 and / or near the other end surface to achieve stable fixation of both ends of the sealed pressure-bearing shell 1.

[0063] In this solution, the heat exchange structure is installed from the bottom to the top from the space between the civil structure and the main compartment of the loading and unloading cycle into the annular space between the civil structure and the discharge pipe shield. In order to reduce the difficulty of installing the heat exchange structure, the civil structure needs to be improved. Specifically, the civil structure has a cavity for accommodating the discharge pipe shield, and the cavity wall of the cavity is adapted to the shape of the discharge pipe shield. This solution enlarges the diameter of the cavity near one end of the main compartment of the loading and unloading cycle, and the inside of the cavity is stepped, so that the heat exchange structure can be installed from the bottom to the top from the space between the civil structure and the main compartment of the loading and unloading cycle into the annular space between the civil structure and the discharge pipe shield.

[0064] The heat exchange structure is installed from bottom to top. After the connection between the heat exchange structure and the civil structure is released, the heat exchange structure slides down under the action of its own gravity, and the disassembly process is relatively simple.

[0065] The heat exchange component 2 has various forms. In some embodiments, the heat exchange component 2 is a heat pipe heat exchange component; in other embodiments, the heat exchange component 2 is a baffle heat exchange component.

[0066] In the embodiment where the heat exchange component 2 is a baffle heat exchange component, the baffle may be an arc-shaped baffle or a baffle of other shapes, and the heat exchange medium turns back and forth in the flow channel of the baffle.

[0067] In the embodiment where the heat exchange assembly 2 is a heat pipe heat exchange assembly, the heat exchange assembly 2 includes a liquid inlet pipe 21, a liquid inlet manifold 25, a plurality of heat exchange tubes 26, a liquid outlet manifold 27 and a liquid outlet pipe 22. The liquid inlet pipe 21 is connected to the liquid inlet manifold 25, the liquid inlet manifold 25 is connected to the liquid inlet ends of the plurality of heat exchange tubes 26, the liquid outlet ends of the plurality of heat exchange tubes 26 are connected to the liquid outlet manifold 27, and the liquid outlet manifold 27 is connected to the liquid outlet pipe 22. The heat exchange medium is supplied from the liquid inlet pipe 21 and collected to the liquid inlet manifold 25. The liquid inlet manifold 25 distributes the heat exchange medium to each heat exchange tube 26. After heat exchange, the heat exchange medium is collected to the liquid outlet manifold 27 and finally flows out through the liquid outlet pipe 22. Adjacent heat exchange tubes 26 are arranged side by side in parallel.

[0068] The liquid inlet pipe 21, the liquid inlet manifold 25, the plurality of heat exchange pipes 26, the liquid outlet manifold 27 and the liquid outlet pipe 22 are welded. Optionally, the pipe diameters of the liquid inlet manifold 25 and the liquid outlet manifold 27 are greater than or equal to the diameter of the heat exchange pipe 26.

[0069] In some embodiments, the liquid inlet pipe 21, the liquid inlet manifold 25, the plurality of heat exchange tubes 26, the liquid outlet manifold 27 and the liquid outlet pipe 22 are all circular tubes.

[0070] In some embodiments, the liquid inlet pipe 21 and the liquid outlet pipe 22 are circular pipes, and the liquid inlet manifold 25, the plurality of heat exchange pipes 26, and the liquid outlet manifold 27 are all semicircular pipes, and the open ends of the semicircular pipes are directly welded to the inner wall of the inner arc of the arc shell, so that the heat absorbed by the inner ring of the arc shell can be directly transferred to the heat exchange pipe 26, shortening the heat conduction path and improving the heat exchange efficiency. The liquid inlet manifold 25, the plurality of heat exchange pipes 26, the liquid outlet manifold 27, and the inner wall of the inner ring of the arc shell constitute the flow channel space of the heat exchange component 2, and the flow channel space is placed in the sealed and pressure-bearing arc shell. If the seal between the liquid inlet manifold 25, the plurality of heat exchange pipes 26, the liquid outlet manifold 27 and the arc shell fails and leaks, the leaked heat exchange medium will flow into the arc shell.

[0071] In the embodiment where the heat exchange assembly 2 is a heat pipe heat exchange assembly, the heat exchange tube 26 can be arranged along the axial direction of the arc-shaped shell, or can be arranged along the axial direction perpendicular to the arc-shaped shell. When the heat exchange tube 26 is arranged along the axial direction of the arc-shaped shell, the heat exchange tube 26 is a straight tube, and when the heat exchange tube 26 is arranged along the axial direction perpendicular to the arc-shaped shell, the heat exchange tube 26 is an arc-shaped tube.

[0072] No matter the heat exchange tube 26 is arranged along the axial direction of the arc-shaped shell or perpendicular to the axial direction of the arc-shaped shell, the liquid inlet pipe 21 and the liquid outlet pipe 22 can be respectively located at both ends of the length direction of the heat exchange tube 26, or the liquid outlet pipe 22 can be folded back to a position adjacent to the liquid inlet pipe 21 to realize the centralized arrangement of the liquid inlet pipe 21 and the liquid outlet pipe 22.

[0073] The lengths of the heat exchange tubes 26 between the inlet manifold 25 and the outlet manifold 27 are equal, the heat exchange paths of the heat exchange medium flowing through the heat exchange tubes 26 are equidistant, and the flow resistance generated by the heat exchange medium flowing through the heat exchange tubes 26 is the same, which is beneficial to the distribution of the heat exchange medium in the multiple heat exchange tubes 26 and improves the uniformity of heat exchange. The distances of the fluid flowing through each flow channel are the same, and the resistances generated along the way are the same, so it is easy to reach a hydraulic balance state.

[0074] The heat exchange assembly 2 can be arranged on the inner ring of the arc shell or on the outer ring of the arc shell. The heat exchange tubes 26 of the heat exchange assembly 2 can be arranged in only one layer, two layers or more layers along the inner ring and / or outer ring of the arc shell.

[0075] In the present solution, the liquid inlet pipe 21 and the liquid outlet pipe 22 of the modular heat exchange device that can be assembled and disassembled can be located outside the civil structure and extend into the main compartment of the loading and unloading cycle. The bottom surface of the sealed pressure-bearing shell 1 is in contact with the upper surface of the main compartment of the loading and unloading cycle, and the liquid inlet pipe 21 and the liquid outlet pipe 22 are connected to the cooling water of the equipment in the factory through open pipes.

[0076] Optionally, the outer ring of the sealed pressure-bearing shell 1 does not fit the cavity wall of the civil structure.

[0077] The assembleable and detachable modular heat exchange device of the present solution is connected to the embedded parts professionally reserved for the civil engineering device through the support 23, further optimizing the connection strength between the assembleable and detachable modular heat exchange device and the civil engineering structure. Optionally, the support 23 and the embedded parts are connected by bolts, and the support 23 is welded to the sealed pressure-bearing shell 1 of the assembleable and detachable modular heat exchange device.

[0078] The number, position and height of the supports 23 are selected by those skilled in the art based on actual needs, such as the weight of the assembleable and detachable modular heat exchange device, and are not specifically limited here.

[0079] The support 23 may be a cylindrical seat, a truncated cone seat, a prism-shaped seat or other shapes, which are not specifically limited here.

[0080] The end surface of the sealed pressure-bearing housing 1 on which the support 23 is disposed may also be provided with a buckle 11 and a hook 12 at the same time.

[0081] In this scheme, there is a certain gap between the sealed pressure-bearing shell 1 and the discharge pipe shield of the modular heat exchange device that can be assembled and disassembled. The modular heat exchange device that can be assembled and disassembled disclosed in this application also includes a forced heat exchange pipe 24 that penetrates the sealed pressure-bearing shell 1. The forced heat exchange pipe 24 is used to supply gas between the sealed pressure-bearing shell 1 and the discharge pipe shield, forcing the gas between the sealed pressure-bearing shell 1 and the discharge pipe shield to flow, thereby enhancing the heat exchange effect.

[0082] In some embodiments, the forced heat exchange tube 24 is arranged upwardly and inclined relative to the radial direction of the sealed pressure-bearing shell 1, and is arranged at the lower end of the sealed pressure-bearing shell 1, so as not to produce an interface with the civil engineering device, thereby minimizing the installation impact involving the interface between the civil engineering and reducing the difficulty of disassembly and maintenance of the assembleable and disassembled modular heat exchange device to a certain extent.

[0083] In some embodiments, the sealed pressure-bearing shell 1 of the assemble-and-disassemble modular heat exchange device may also be closely connected to the discharge shield.

[0084] The assembleable and detachable modular heat exchange device disclosed in the present application is arranged between the civil engineering structure and the heat exchange tube shielding, so that the overall structure of the assembleable and detachable modular heat exchange device is relatively small and the cost is relatively reduced.

[0085] Only one assembleable and disassembled modular heat exchange device can be set in the length extension direction of the discharge pipe shield, or multiple assembleable and disassembled modular heat exchange devices can be arranged in sequence along the length direction of the discharge pipe shield. The multiple assembleable and disassembled modular heat exchange devices form multiple heat exchange rings on the discharge pipe shield, and two adjacent assembleable and disassembled modular heat exchange devices along the length direction of the discharge pipe shield can be detachably connected.

[0086] In this solution, the assembleable and disassembled modular heat exchange device has multiple independent heat exchange structures. The size of a single heat exchange structure is relatively small, and the number of heat exchange structures can be flexibly selected according to the place of use. The assembly, transportation and installation are easy.

[0087] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used, and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. The scope of application involved in the present application is not limited to the technical solution formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned application concept. For example, the above-mentioned features are replaced with the technical features with similar functions disclosed in this application (but not limited to) to form a technical solution.
