Description

Technical Field

[0001] This utility model relates to the field of condenser equipment technology, specifically to a spiral wound heat exchange tube bundle for condensers. Background Technology

[0002] A condenser is a device that cools a gas or vapor and converts it into a liquid. It's a component of a refrigeration system, a type of heat exchanger, that transforms gas or vapor into liquid. It rapidly transfers heat from the tubes to the surrounding air. The cooling medium flowing inside the condenser (usually water or other coolant) absorbs the heat from the gas or vapor, lowering its temperature and causing it to condense into a liquid. The condenser's operation is exothermic, hence the relatively high temperature. A spiral-wound heat exchanger tube bundle is a type of heat exchange element in a condenser. By winding spiral tubes inside a shell, it achieves efficient heat transfer. The spiral-wound heat exchanger tube bundle mainly consists of a shell, spiral tubes, inlet and outlet, and supports. The spiral tubes are the core component, formed by multiple spirals wound together. The gaps between the spirals allow the coolant to flow through and contact the high-temperature gas, thus achieving cooling. The inlet and outlet are the channels for coolant inflow and outflow, and the supports are used to fix the spiral tubes. The spiral winding design increases the heat exchange area and shortens the heat transfer distance, thereby improving heat transfer efficiency. Furthermore, the spiral-wound heat exchanger tube bundle employs a compact design. It can achieve large-area heat transfer in a small space, effectively saving equipment volume and space occupation; and due to its simple structure and convenient disassembly and assembly, the cleaning and maintenance of the spiral wound heat exchange tube bundle becomes simple and easy. In summary, the condenser is an important heat exchange device with wide applications in many fields, and the spiral wound heat exchange tube bundle, as a high-efficiency heat exchange element in the condenser, has the advantages of improving heat transfer efficiency, saving space and being easy to clean, providing strong support for the widespread application of condensers. Currently, the condensers widely used in the market generally face a problem during the replacement of their internal heat exchange tube bundles: the liquid inside the pipes is prone to leakage. If the condensate contains corrosive components, this leakage will not only have an adverse impact on the production environment, such as corroding equipment and polluting the production area, but may also pose a health risk to the workers performing the replacement work, causing potential harm such as skin irritation and respiratory problems. Therefore, this problem urgently needs a more effective solution to improve it. For the above problem, there may already be technical means to solve it in the existing technology, but this case aims to provide an alternative or replacement technical solution. Utility Model Content

[0003] To achieve the above objectives, this utility model is implemented through the following technical solution: a spiral wound heat exchange tube bundle for a condenser, comprising: a first pipe shell, a pair of second pipe shells, and a pair of inner housing rings, wherein the pair of inner housing rings are respectively inserted into the first pipe shell, the pair of second pipe shells are respectively connected to the first pipe shell, an integrated heat exchange bundle structure is installed inside the first pipe shell, and a pair of emergency sealing components are respectively installed inside the second pipe shells;

[0004] The integrated heat exchange bundle structure includes: a pair of auxiliary sealing rings, several main body locking keys, several accessory locking keys, several locking and sealing plugs, a main heat exchange tube bundle, several branch tube bundles, a pair of connecting airway tubes, a pair of connecting infusion tubes, a pair of infusion tube valves, and a pair of airway tube valves.

[0005] A pair of auxiliary sealing rings are respectively installed on a pair of inner housing rings, and the pair of auxiliary sealing rings are respectively connected to the second pipe housing. A plurality of main locking keys are respectively installed on the first pipe housing, and the plurality of main locking keys are respectively connected to a plurality of accessory locking keys. A plurality of accessory locking keys are respectively installed on a pair of second pipe housings. A plurality of locking closure plugs are respectively inserted into a plurality of main locking keys and a plurality of accessory locking keys. The main heat exchange tube bundle is respectively installed on a pair of inner housing rings. A plurality of branch tube bundles are respectively installed on a pair of inner housing rings, and the plurality of branch tube bundles are respectively fitted onto the outside of the main heat exchange tube bundle. A pair of connecting air ducts are respectively installed on the first pipe housing, and the pair of connecting air ducts are respectively connected to a pair of air duct valves. A pair of connecting infusion tubes are respectively installed on a pair of second pipe housings, and the pair of connecting infusion tubes are respectively connected to a pair of infusion tube valves.

[0006] It should be noted that, as described above, the high-temperature gas requiring cooling is transported through a pipeline to the gas duct valve on one side of the first pipe shell, with the outlet end connected to the gas duct valve on the opposite side. The refrigerant enters through the liquid inlet valve on the second pipe shell, flows into the second pipe shell, and then flows through the main heat exchange tube bundle and multiple branch tube bundles on the inner housing ring into the opposite second pipe shell, before exiting from the liquid inlet valve on the opposite side. At this time, the main heat exchange tube bundle and multiple branch tube bundles can perform heat exchange on the high-temperature gas passing through the first pipe shell, completing the heat exchange operation of the condenser tube bundle. A pair of auxiliary sealing rings provide auxiliary sealing, ensuring that the first pipe shell and the pair of second pipe shells maintain a relatively closed inner ring. The four main locking keys and four auxiliary locking keys, along with the corresponding four locking bolts, allow the second pipe shell to be tightly integrated with the first pipe shell as a whole, thus enhancing the integrity of the entire heat exchange tube bundle. The auxiliary corrosion-resistant coating inside the main heat exchange tube bundle further improves its overall durability. The insulation layer inside the first pipe shell minimizes the impact of external factors on the high-temperature gas inside. The mounting flange on the first pipe shell ensures the entire heat exchange bundle device is securely placed in one location, making its operation more stable. The flow rate monitor inside the first pipe shell allows workers to better monitor and control the flow rate of the high-temperature gas inside the first pipe shell.

[0007] Preferably, the emergency sealing assembly includes: an assembly mounting ring, an air injection port, a pair of telescopic air rods, and an inner sealing plate;

[0008] The component mounting ring is installed inside the second pipe housing, the air injection port is installed on the second pipe housing and is connected to the component mounting ring, and a pair of telescopic air rods are respectively installed on the component mounting ring and are respectively connected to the inner sealing plate of the pipe;

[0009] It should be noted that, as described above, when the heat exchange tube bundle needs to be repaired or replaced, air can be injected into one or both air injection ports. The gas enters the component mounting ring, causing the corresponding pair of telescopic air rods to extend until the inner sealing plate of the tube adheres to and tightly presses against the surface of the inner mounting ring. This blocks the through holes of the multiple branch tube bundles and the channel opening of the main heat exchange tube bundle on the inner mounting ring. Therefore, when the outer shell of the second pipe on one side is disassembled, the coolant remaining in the branch tube bundle and the main heat exchange tube bundle will not flow out under atmospheric pressure, thus preventing leakage.

[0010] Preferably, the main heat exchange tube bundle is provided with an auxiliary corrosion-resistant coating;

[0011] Preferably, the first pipe shell is provided with a heat insulation layer;

[0012] Preferably, a mounting flange is provided on the outer shell of the first pipe;

[0013] Preferably, a flow rate monitor is installed inside the outer shell of the first pipe. Beneficial effects

[0014] This invention provides a spirally wound heat exchange tube bundle for a condenser. It offers the following advantages: Compared to existing technologies, this spirally wound heat exchange tube bundle integrates a heat exchange bundle structure, enabling efficient operation and heat exchange of high-temperature gas within multiple branch tube bundles and the main heat exchange tube bundle. Furthermore, with the aid of an emergency sealing component, it can quickly and effectively seal off any residual refrigerant inside the heat exchange tube bundle. This feature is particularly important when the heat exchange tube bundle needs maintenance or replacement, as it fundamentally prevents leakage of residual coolant inside the pipes, greatly facilitating subsequent harmless treatment processes. In this way, we not only ensure a clean and safe working environment but also effectively protect the health and safety of operators and maintenance workers, truly achieving the dual goals of environmental friendliness and personnel protection.

The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further. Example

[0020] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-2As shown, a condenser uses a spirally wound heat exchange tube bundle, comprising: a first pipe shell 1, a pair of second pipe shells 2, and a pair of inner housing rings 3. The pair of inner housing rings 3 are respectively inserted into the first pipe shell 1, and the pair of second pipe shells 2 are respectively connected to the first pipe shell 1.

A pair of air duct valves; 13. A pair of auxiliary sealing rings 4 are respectively installed on a pair of inner housing rings 3, and the pair of auxiliary sealing rings 4 are respectively connected to the second pipe housing 2; several main body locking keys 5 are respectively installed on the first pipe housing 1, and the several main body locking keys 5 are respectively connected to several accessory locking keys 6; several accessory locking keys 6 are respectively installed on a pair of second pipe housings 2; several... Each of the aforementioned locking and sealing plugs 7 is inserted into a plurality of the main body locking keys 5 and a plurality of the appendage locking keys 6. The main heat exchange tube bundles 8 are respectively mounted on a pair of the inner shell mounting rings 3. A plurality of the branch tube bundles 9 are respectively mounted on a pair of the inner shell mounting rings 3, and the plurality of the branch tube bundles 9 are respectively fitted onto the outside of the main heat exchange tube bundles 8. A pair of connecting airway tubes 10 are respectively mounted on the first pipe outer shell 1, and the pair of connecting airway tubes 10 are respectively connected to a pair of airway tube valves 13. A pair of connecting infusion tubes 11 are respectively mounted on a pair of the second pipes. The first pipe housing 2 is equipped with a pair of infusion tubes 11 connected to a pair of infusion tube valves 12. The emergency sealing assembly includes: an assembly mounting ring 14, an air injection port 15, a pair of telescopic air rods 16, and an inner sealing plate 17. The assembly mounting ring 14 is installed inside the second pipe housing 2. The air injection port 15 is installed on the second pipe housing 2 and is connected to the assembly mounting ring 14. The pair of telescopic air rods 16 are installed on the assembly mounting ring 14 and are connected to the inner sealing plate 17.

[0021] According to the appendix Figure 1-2The process involves transporting the high-temperature gas requiring cooling through a pipeline to the gas duct valve 13 on one side of the first pipe shell 1, connected to the gas duct 10. The outlet end is connected to the gas duct valve 13 on the opposite side. The refrigerant enters through the liquid delivery valve 12 on the liquid delivery pipe 11 of the second pipe shell 2, flows into the second pipe shell 2, and then flows through the main heat exchange tube bundle 8 and multiple branch tube bundles 9 on the inner housing ring 3 into the opposite side of the second pipe shell 2. Finally, it flows out from the liquid delivery valve 12 on the opposite side. At this point, the main heat exchange tube bundle 8 and the multiple branch tube bundles... 9. The high-temperature gas passing through the first pipe shell 1 can undergo heat exchange treatment to complete the heat exchange operation of the condenser tube bundle. A pair of auxiliary sealing rings 4 can provide auxiliary sealing, so that the first pipe shell 1 and the pair of second pipe shells 2 maintain a relatively closed cavity environment. The four main locking keys 5 and the four auxiliary locking keys 6, together with the corresponding four locking and sealing bolts 7, can tightly connect the pair of second pipe shells 2 and the first pipe shell 1 into a whole, thereby making the entire heat exchange tube bundle more integrated. The auxiliary corrosion-resistant coating set in the main heat exchange tube bundle 8 can further improve the overall durability of the main heat exchange tube bundle 8. The heat insulation layer set in the first pipe shell 1 can minimize the impact of the external environment on the high-temperature gas in the first pipe shell 1. The mounting flange set on the first pipe shell 1 can securely place the entire heat exchange bundle device in a certain place, making the operation more stable. The flow rate monitor set in the first pipe shell 1 can allow workers to better grasp and control the flow rate of the high-temperature gas in the first pipe shell 1. When the heat exchange tube bundle needs maintenance and replacement... When the gas is charged, it can be charged into one side of the gas inlet 15 or a pair of gas inlets 15. The gas enters the component mounting ring 14, which causes the corresponding pair of telescopic gas rods 16 to extend until the inner sealing plate 17 is attached to and tightly pressed against the surface of the inner mounting ring 3. This blocks the through holes of the multiple branch tube bundles 9 on the inner mounting ring 3 and the channel opening of the main heat exchange tube bundle 8. Therefore, when the second pipe outer shell 2 on one side is disassembled, the coolant remaining in the branch tube bundles 9 and the main heat exchange tube bundle 8 will not flow out under atmospheric pressure, thus preventing leakage.
