Description

Technical Field

[0001] This invention relates to the field of condenser vibration reduction and noise reduction technology, and in particular to a low-noise direct-mix condenser. Background Technology

[0002] Evaporative condensers, as highly efficient and energy-saving heat exchange equipment, are widely used in industrial fields such as food processing, pharmaceutical manufacturing, and chemical production. They achieve rapid heat exchange by utilizing the latent heat of vaporization of water through the synergistic effect of a sprayed liquid film and forced convection. However, during the operation of existing condenser equipment, the high-speed impact of the sprayed liquid film on the condenser shell can easily induce high-frequency mechanical vibrations in the condenser shell due to the kinetic energy of the fluid, generating continuous broadband noise pollution. Therefore, long-term exposure to this type of structural noise environment is more likely to cause occupational health problems such as hearing loss and neurasthenia in workers. Summary of the Invention

[0009] According to the low-noise direct-mix condenser of this application embodiment, when the liquid film formed by the nozzle impacts the buffer plate, the buffer plate will be subjected to the force of the liquid film and move towards the condenser shell, driving the first magnetic component to move towards the condenser shell in the non-magnetic cylinder. Based on the principle of electromagnetic induction, the changing magnetic field generated by the movement of the first magnetic component will cause the non-magnetic cylinder to cut magnetic field lines, thereby generating an induced current in the non-magnetic cylinder. The accompanying magnetic field of the induced current will, in turn, act on the magnet, hindering its movement and slowing down its speed, thus acting as a buffer against the impact force of the liquid film.

[0011] According to one embodiment of this application, the buffer assembly includes a non-magnetic rod, a first end of the first magnetic element is connected to the non-magnetic rod, and the second magnetic element has an inner hole, through which the non-magnetic rod is movably inserted.

[0012] According to one embodiment of this application, the opening area of ​​the inner hole is larger than the cross-sectional area of ​​the non-magnetic rod.

[0013] According to one embodiment of this application, the buffer assembly includes a rolling structure disposed between the first magnetic element and the non-magnetic straight cylinder to reduce motion resistance.

[0046] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but should not be used to limit the scope of this application.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0051] As power plant output gradually increases, the size of their steam condensers also gradually increases, thus creating an urgent need to improve the heat exchange capacity of steam condensers. Traditional steam condensers can be divided into shell-and-tube indirect condensers and hybrid condensers. Among them, shell-and-tube indirect condensers use an indirect heat exchange method where steam flows through the shell side and cooling water flows through the tube side, resulting in a lower overall heat transfer coefficient and a large volume; while hybrid condensers use a phase change heat exchange method where steam and cooling water directly contact each other for condensation, resulting in a very high heat transfer coefficient and effectively reducing the condenser volume.

[0052] In related technologies, the hybrid condenser used in power plants employs a water spray assembly in the center of the condenser to form a stable liquid film. An external pump supplies water to the condenser, and nozzles are installed on the spray assembly to atomize the water into a liquid film for efficient heat exchange with the steam. However, the relatively high-speed water jets ejected from the nozzles impact the condenser casing, causing vibrations.

[0053] To address the issue of vibration caused by water jets impacting the condenser housing, this solution proposes a low-noise direct-mix condenser, aiming to reduce the noise generated by the liquid film impacting the condenser housing.

[0054] The following is combined Figures 1-6 The present invention describes a low-noise direct-mix condenser.

[0055] According to an embodiment of this application, a low-noise direct-mix condenser is proposed. Please refer to... Figures 1 to 3 The system includes: a condenser housing 8, a buffer plate 30, a buffer assembly 31, and a water spray assembly 3. The condenser housing 8 has a condensation chamber 2 inside; the buffer assembly 31 includes a non-magnetic straight cylinder 32 and a first magnetic element 33. The non-magnetic straight cylinder 32 is installed on the inner wall of the condensation chamber 2, and a buffer cavity 34 is provided inside the non-magnetic straight cylinder 32. The first end of the first magnetic element 33 is movably inserted through the buffer cavity 34, and the second end of the first magnetic element 33 is connected to the buffer plate 30; the water spray assembly 3 is installed inside the condensation chamber 2, and the water spray assembly 3 has nozzles 5 facing the buffer plate 30.

[0056] According to the condenser of this application embodiment, when the liquid film 4 formed by the nozzle 5 impacts the buffer plate 30, the buffer plate 30 will be subjected to the force of the liquid film 4 and move towards the condenser housing 8, causing the first magnetic element 33 to move towards the condenser housing 8 in the non-magnetic cylinder 32. According to the principle of electromagnetic induction, the changing magnetic field generated by the movement of the first magnetic element 33 will cause the non-magnetic cylinder 32 to cut the magnetic field lines, thereby generating an induced current in the non-magnetic cylinder 32. The accompanying magnetic field of the induced current will, in turn, act on the magnet, hindering its movement and slowing down the magnet's movement speed, thus buffering the impact force of the liquid film 4.

[0057] Understandably, the condenser shell 8 is the external frame structure of the entire condenser, and it can be made of high-strength, corrosion-resistant materials, such as stainless steel. Inside the condenser shell 8 is a condensation chamber 2, which provides a relatively enclosed space for the condensation process, allowing the medium to be condensed to undergo effective heat exchange, thereby achieving the transformation from a gaseous state to a liquid state.

[0058] The primary function of the buffer plate 30 is to withstand the impact force of the liquid film 4 sprayed from the water spray assembly 3. When the liquid film 4 impacts the buffer plate 30 at high speed, the buffer plate 30 will deform and move to a certain extent, thereby absorbing and dispersing the energy of the liquid film 4 and reducing the impact on other components inside the condenser. The buffer plate 30 is usually made of materials with a certain degree of elasticity and strength, such as rubber or metal composite materials, to ensure that it can effectively buffer the impact force of the liquid film 4.

[0059] When the liquid film 4 formed by the nozzle 5 impacts the buffer plate 30, the buffer plate 30 is subjected to the force of the liquid film 4 and moves towards the condenser housing 8. Since the second end of the first magnetic element 33 is connected to the buffer plate 30, the movement of the buffer plate 30 will cause the first magnetic element 33 to move towards the condenser housing 8 within the non-magnetic cylinder 32. According to the principle of electromagnetic induction, the changing magnetic field generated by the movement of the first magnetic element 33 will cause the non-magnetic cylinder 32 to cut magnetic field lines, thereby generating an induced current in the non-magnetic cylinder 32. The induced current will generate a companion magnetic field, which will in turn act on the first magnetic element 33, hindering its movement and slowing down its movement speed. This, in turn, slows down the movement speed of the buffer plate 30, thus buffering the impact force of the liquid film 4. This buffering method can effectively protect the structure of the condenser and prevent damage to components due to excessive impact force of the liquid film 4.

[0060] According to one embodiment of this application, the buffer assembly 31 includes a second magnetic element 35. The second magnetic element 35 is provided on the side of the buffer cavity 34 near the inner wall. The side of the second magnetic element 35 near the first magnetic element 33 has the same magnetic pole as the first end of the first magnetic element 33.

[0061] A second magnetic element 35 is disposed on the side of the buffer cavity 34 near the inner wall, and the side of the second magnetic element 35 near the first magnetic element 33 has the same magnetic pole as the first end of the first magnetic element 33. According to the principle that "like poles repel each other", when the first magnetic element 33 moves toward the condenser shell 8 under the impact force of the liquid film 4, the second magnetic element 35 will generate an additional repulsive force on the first magnetic element 33. This repulsive force, together with the accompanying magnetic field force generated by the electromagnetic induction of the first magnetic element 33, further hinders the movement of the first magnetic element 33, thereby enhancing the effect of the impact force of the buffer film 4 and more effectively protecting the internal structure of the condenser.

[0062] The second magnetic element 35 causes the buffer assembly 31 to be subjected to two forces during the buffering process (the force of the accompanying magnetic field generated by electromagnetic induction and the repulsive force of the second magnetic element 35). These two forces work together to make the movement of the first magnetic element 33 more stable.

[0063] According to one embodiment of this application, the buffer assembly 31 includes a non-magnetic rod 36, a first end of a first magnetic element 33 is connected to the non-magnetic rod 36, and a second magnetic element 35 is provided with an inner hole 37, through which the non-magnetic rod 36 can be movably inserted.

[0064] It is understandable that when the first magnetic element 33 moves toward the second magnetic element 35, the non-magnetic rod 36 at the first end of the first magnetic element 33 will pass through the second magnetic element 35, and an induced current will be generated to hinder the movement of the non-magnetic rod 36.

[0065] The combined effect of the induced current's resistance, the repulsive force of the second magnetic element 35 on the first magnetic element 33, and the accompanying magnetic field force generated by the non-magnetic straight cylinder 32 cutting magnetic field lines during electromagnetic induction, further enhances the buffering effect of the buffer assembly 31 on the impact force of the liquid film 4. These multiple resistance forces more effectively slow down the movement speed of the first magnetic element 33 and reduce the movement amplitude of the buffer plate 30, thereby better protecting the internal structure of the condenser.

[0066] According to one embodiment of this application, the opening area of ​​the inner hole 37 is larger than the cross-sectional area of ​​the non-magnetic rod 36.

[0067] Understandably, when the opening area of ​​the inner hole 37 is larger than the cross-sectional area of ​​the non-magnetic rod 36, sufficient space is provided for the movement of the non-magnetic rod 36 within the inner hole 37 of the second magnetic component 35. When the first magnetic component 33 moves under the impact force of the liquid film 4, the non-magnetic rod 36 can move freely within the inner hole 37 without getting stuck against the wall of the inner hole 37 due to its small size.

[0068] According to one embodiment of this application, the buffer assembly 31 includes a rolling structure 38 disposed between the first magnetic element 33 and the non-magnetic straight cylinder 32 to reduce motion resistance.

[0069] A rolling structure 38 is disposed between the first magnetic component 33 and the non-magnetic straight cylinder 32 to reduce motion resistance. The rolling structure 38 is a device that enables rolling friction between two relatively moving components. The rolling structure 38 can consist of rolling elements (such as balls, rollers, needle rollers, etc.) and a cage. The rolling elements roll between the two components, transforming the original sliding friction into rolling friction, thereby greatly reducing motion resistance.

[0070] According to one embodiment of this application, the rolling structure 38 is a flexible rolling structure 38.

[0071] Understandably, the flexible rolling structure 38 is positioned between the first magnetic component 33 and the non-magnetic straight cylinder 32 to reduce motion resistance. The flexible rolling structure 38 is a special type of rolling structure 38 that combines the characteristics of a rolling structure 38 and a flexible material. Flexible materials are deformable and can adapt to different shapes and stress conditions to a certain extent. The flexible rolling structure 38 can consist of rolling elements made of flexible material (such as rubber balls, silicone rollers, etc.) and a cage. The rolling elements roll between the two components, while the flexible material undergoes slight deformation to better adapt to the relative movement and contact between the first magnetic component 33 and the non-magnetic straight cylinder 32.

[0072] According to one embodiment of this application, a snap-fit ​​structure 39 is provided at one end of the non-magnetic straight cylinder 32 near the buffer plate 30, and the opening area of ​​the snap-fit ​​structure 39 is smaller than the cross-sectional area of ​​the first end of the first magnetic element 33.

[0073] The opening area of ​​the snap-fit ​​structure 39 is smaller than the cross-sectional area of ​​the first end of the first magnetic component 33, preventing the first magnetic component 33 from detaching from the non-magnetic cylinder 32 through the opening of the snap-fit ​​structure 39 when it moves to the position of the snap-fit ​​structure 39. When the first magnetic component 33 is subjected to forces such as the impact force of the liquid film 4, it will move inside the non-magnetic cylinder 32. However, due to the obstruction of the snap-fit ​​structure 39, the first magnetic component 33 can only move within the limited space between the snap-fit ​​structure 39 and the buffer plate 30, thereby effectively preventing the first magnetic component 33 from detaching from the non-magnetic cylinder 32 and ensuring the normal operation of the buffer assembly 31.

[0074] According to one embodiment of this application, there are multiple buffer components 31, which are distributed along the extension direction of the buffer plate 30.

[0075] When the liquid film 4 impacts the buffer plate 30, the force is distributed across multiple buffer components 31 along the extension direction of the buffer plate 30. Each buffer component 31 buffers the force to a certain extent, thus preventing the force from concentrating on one or a few points and making the buffering effect more uniform.

[0076] Meanwhile, in practical applications, the distribution of force on the buffer plate 30 is often uneven. By setting multiple buffer components 31, the number and position of the buffer components 31 can be reasonably adjusted according to the actual distribution of the force, so that each buffer component 31 can give full play to its buffering effect and further improve the uniformity of buffering.

[0077] According to one embodiment of this application, the non-magnetic straight cylinder 32 is one of a copper straight cylinder, a stainless steel straight cylinder, or a titanium alloy straight cylinder.

[0078] According to one embodiment of this application, the buffer plate 30 is one of stainless steel plate, aluminum alloy plate, and titanium alloy plate.

[0079] In one embodiment, a steam inlet 2131 is provided above the condenser housing 8, and a condensate outlet 279 is provided at the bottom of the condenser housing 8.

[0080] In one embodiment, the bottom of the water spray assembly 3 is provided with an air extraction device 11, which is connected to a cooling water pipe 10.

[0081] The condenser of this application is described below with reference to a specific embodiment:

[0082] As shown in the figure, a buffer plate 30 is installed on the inner wall of the shell where the condenser collides with the liquid film 4. The buffer plate 30 is made of corrosion-resistant materials such as stainless steel, aluminum alloy, and titanium alloy.

[0083] The buffer plate 30 has several first magnetic components 33 installed on its back. The first magnetic components 33 can be various shapes such as cylindrical or cubic.

[0084] One end of the first magnetic component 33 is fastened to the buffer plate 30, and the other end is placed in the straight cylinder. The shape of the straight cylinder matches the magnetic block. The material of the straight cylinder can be non-magnetic materials such as copper and stainless steel. Here, copper is used as an example for explanation.

[0085] A latch is provided between the first magnetic component 33 and the non-magnetic straight cylinder 32 to prevent the first magnetic component 33 from detaching from the non-magnetic straight cylinder 32.

[0086] The bottom of the non-magnetic straight cylinder 32 is also fixed with a second magnetic component 35. The second magnetic component 35 has the same magnetic pole as the side facing the first magnetic component 33 on the buffer plate 30, so that the two magnetic blocks are in a repulsive state.

[0087] At the lower front end of the first magnetic component 33, several rolling structures 38 can be arranged, which can not only reduce the resistance when the first magnetic component 33 moves, but also reduce the direct transmission of vibration to the non-magnetic straight cylinder 32.

[0088] A non-magnetic rod 36 is installed at the middle of the front end of the first magnetic component 33. Correspondingly, a through hole 7 slightly larger than the non-magnetic rod 36 is opened at the middle of the second magnetic component 35. When the buffer plate 30 moves to the left, the non-magnetic rod 36 will also be inserted into the through hole 7 in the middle of the second magnetic component 35.

[0089] When the liquid film 4 formed by the nozzle 5 impacts the buffer plate 30, the buffer plate 30 will be subjected to a force to the left, thus moving to the left and causing the first magnetic component 33 to move to the left in the non-magnetic cylinder 32. According to the principle of electromagnetic induction, the changing magnetic field generated by the movement of the magnet will cause the non-magnetic cylinder 32 to cut the magnetic field lines, thereby generating an induced current in the non-magnetic cylinder 32. The accompanying magnetic field of the induced current will, in turn, act on the magnet, hindering its movement and slowing down its speed, thus acting as a buffer for the impact force of the buffer film 4.

[0090] Considering that the resistance force generated by the induced current can only slow down the speed of the first magnetic element 33 and cannot completely prevent it from moving to the left, in order to prevent it from colliding with the condenser shell and causing vibration to be transmitted outward, a second magnetic element 35 with the same magnetic pole is installed at the bottom of the non-magnetic straight cylinder 32. As the first magnetic element 33 gets closer, the two magnetic blocks will generate a greater repulsive force, thereby preventing the first magnetic element 33 from hitting the second magnetic element 35.

[0091] When the first magnetic component 33 moves to the left, it also causes the non-magnetic rod 36 mounted at its front end to move to the left and insert into the second magnetic component 35, which in turn generates an induced current to impede the movement of the non-magnetic rod 36.

[0092] The resistive force generated by the two electromagnetic induction principles plays a significant buffering role, preventing a sudden increase in the repulsive force between the two magnets, extending the buffering and vibration isolation time, and acting as a kind of slow pressure relief, thereby greatly reducing the impact of the liquid film 4.

[0093] Throughout the process, since the buffer plate 30 and the first magnetic element 33 do not contact the second magnetic element 35 or the condenser shell, the vibration caused by the impact of the liquid film 4 can be significantly reduced, thereby greatly reducing the vibration noise of the mixing condenser and achieving a low-noise design for the condenser.

[0094] Furthermore, when the mixing condenser stops operating, the nozzle 5 no longer generates the liquid film 4, and the impact force applied to the buffer plate 30 will disappear. At this time, under the action of the repulsive force of the magnetic block, the first magnetic element 33 will move to the right. The additional resistance force generated by the electromagnetic induction current will hinder the first magnetic element 33 from moving to the right, thus slowing down its movement to the right. This prevents the first magnetic element 33 from moving to the right quickly under the action of the magnetic repulsive force and hitting the snap-fit ​​structure of the non-magnetic straight cylinder 32. Instead, it moves to the right slowly, so that the mixing condenser can be kept in a low vibration state throughout the process.

[0095] According to an embodiment of this application, a low-noise direct-mix condenser is proposed. Please refer to... Figures 4 to 6The system includes: a condenser housing 8, a water spray assembly 3, a vibration isolation structure 12, and a water spray plate 6. The condenser housing 8 has a condensation chamber 2 inside; the water spray assembly 3 is installed inside the condensation chamber 2, and the water spray assembly 3 has nozzles 5 facing the inner wall of the condenser housing 8; the vibration isolation structure 12 is connected to at least one of the condenser housing 8 and the water spray assembly 3, and the vibration isolation structure 12 has a vibration isolation magnetic element 13; the water spray plate 6 is connected to a matching magnetic element 14. The vibration isolation magnetic element 13 and the matching magnetic element 14 are magnetically repelled. When the matching magnetic element 14 passes through the vibration isolation structure 12, the vibration isolation magnetic element 13 keeps the matching magnetic element 14 in a suspended state, and the water spray plate 6 and the vibration isolation structure 12 do not contact each other.

[0096] According to the embodiments of this application, the low-noise direct-mix condenser uses the magnetic repulsion between the vibration isolation magnetic component 13 and the matching magnetic component 14 to prevent the water spray plate 6 from contacting the condenser shell 8, effectively isolating the transmission path of the vibration energy of the water spray plate 6 to the condenser shell and reducing the noise generated by the spray liquid film 4 impacting the water spray plate 6 on the condenser.

[0097] The condenser shell 8 is the main structural part of the condenser, providing a relatively enclosed space, namely the condensing chamber 2, for the condensation process. The condensing chamber 2 is where the steam undergoes the condensation reaction. The water spray assembly 3 is installed inside the condensing chamber 2 and can spray liquid (usually cooling water) onto the inner wall of the condenser shell 8 through nozzles 5. The vibration isolation structure 12 is used to isolate the transmission of vibration energy from the water spray plate 6. Due to the principle of magnetic repulsion, the vibration isolation magnetic component 13 and the matching magnetic component 14, after being inserted into the vibration isolation structure 12, are suspended under the action of the vibration isolation magnetic component 13, thus preventing the water spray plate 6 from contacting the vibration isolation structure 12.

[0098] During condenser operation, the impact of the spray liquid film 4 on the water distribution plate 6 generates vibration and noise. By setting up a vibration isolation structure 12, and utilizing the magnetic repulsion between the vibration isolation magnetic component 13 and the matching magnetic component 14, the water distribution plate 6 is kept in a suspended state and does not contact the condenser shell 8. In this way, the transmission path of the vibration energy of the water distribution plate 6 to the condenser shell is effectively isolated, greatly reducing the noise generated by the impact of the spray liquid film 4 on the water distribution plate 6 on the condenser.

[0099] Understandably, the nozzle 5 can be carefully designed and arranged to align with the inner wall of the condenser housing 8. When cooling water passes through the spray assembly 3, it is ejected from the nozzle 5 at a certain pressure and speed, forming a uniform liquid film 4 in the condensation chamber 2. This liquid film 4 can effectively absorb heat from the condensation chamber 2, promoting the condensation of gas or vapor.

[0100] In one embodiment, the water spray assembly 3 is located in the middle of the condensation chamber 2, and the water spray assembly 3 can spray a liquid film 4 onto the inner wall of the condensation chamber 2.

[0101] It should be noted that the water spray plate 6 and the vibration isolation structure 12 are neither in direct contact nor indirect contact.

[0102] In one embodiment, the water spray plate 6 is provided with a plurality of through holes 7.

[0103] In one embodiment, a steam inlet 1 is provided above the condenser housing 8, and a condensate outlet 9 is provided at the bottom of the condenser housing 8.

[0104] In one embodiment, the bottom of the water spray assembly 3 is provided with an air extraction device 11, which is connected to a cooling water pipe 10.

[0105] According to one embodiment of this application, the liquid ejected from the nozzle 5 is adapted to form a liquid film 4 in the condensation chamber 2. A vibration isolation structure 12 is disposed in the gaps of the liquid film 4. Specifically, after the liquid is ejected from the nozzle 5, it rapidly spreads out in the condensation chamber 2 to form a liquid film 4. These liquid films 4 flow downwards along the inner wall of the condenser under the influence of gravity and surface tension. Because the vibration isolation structure 12 is carefully disposed in the gaps of the liquid film 4, the liquid film 4 will not collide with the vibration isolation structure 12 during its flow, but will instead fall smoothly onto the water spray plate 6.

[0106] By placing the vibration isolation structure 12 in the gap of the liquid film 4, direct contact between the liquid film 4 and the vibration isolation structure 12 is effectively avoided, thereby preventing the liquid film 4 from generating noise due to impact with the vibration isolation structure 12.

[0107] According to one embodiment of this application, the vibration isolation structure 12 includes a lower vibration isolation unit 15. The lower vibration isolation unit 15 includes a lower mounting plate 16 and a lower non-magnetic cylinder 17. The lower mounting plate 16 is connected to at least one of the condenser housing 8 and the water spray assembly 3. The lower non-magnetic cylinder 17 is connected to the lower mounting plate 16. The lower non-magnetic cylinder 17 has a lower vibration isolation cavity 18 inside. The inner wall of the lower vibration isolation cavity 18 is provided with a lower magnetic block 19. The bottom of the lower vibration isolation cavity 18 is provided with a strong magnetic block 20. The lower part of the matching magnetic element 14 passes through the lower vibration isolation cavity 18. The magnetic pole of the lower part of the matching magnetic element 14 is the same as the magnetic pole of the lower magnetic block 19 and the strong magnetic block 20.

[0108] The lower part of the matching magnetic component 14 passes through the lower vibration isolation cavity 18, and its lower magnetic pole is the same as that of the lower magnetic block 19 and the strong magnetic block 20. According to the principle of magnetism, like magnetic poles repel each other. The lower magnetic block 19 and the strong magnetic block 20 together generate an upward repulsive force on the matching magnetic component 14, so that the water spray plate 6 can be stably suspended above the vibration isolation structure 12. This stable suspension state effectively isolates the vibration energy of the water spray plate 6 from the transmission to the condenser shell 8, and greatly reduces the noise generated by the spray liquid film 4 impacting the water spray plate 6 on the condenser.

[0109] The lower mounting plate 16 is connected to at least one of the condenser housing 8 and the water spray assembly 3. This connection method allows for some flexibility in the installation position of the lower vibration isolation unit 15. A suitable connection position can be selected according to actual needs to optimize the vibration isolation effect.

[0110] According to one embodiment of this application, the lower non-magnetic straight cylinder 17 is one of a copper straight cylinder, a stainless steel straight cylinder, or a titanium alloy straight cylinder.

[0111] The lower non-magnetic straight cylinder 17 provides space for the installation and movement of the matching magnetic component 14, while avoiding interference with the magnetic effect itself. The lower non-magnetic straight cylinder 17 is connected to the lower mounting plate 16, and the connection method can be welding, bolting, etc., to ensure the firmness and stability of the connection.

[0112] The lower non-magnetic straight cylinder 17 contains a lower vibration isolation cavity 18. The inner wall of the lower vibration isolation cavity 18 is provided with a lower magnetic block 19, and the bottom of the lower vibration isolation cavity 18 is provided with a strong magnetic block 20. Both the lower magnetic block 19 and the strong magnetic block 20 are made of high-performance magnetic materials and have high magnetic strength. The lower magnetic block 19 is evenly distributed on the inner wall of the lower vibration isolation cavity 18, forming a strong magnetic repulsive force field together with the strong magnetic block 20.

[0113] The lower part of the matching magnetic component 14 passes through the lower vibration isolation cavity 18, and the magnetic poles of the lower part of the matching magnetic component 14 are the same as those of the lower magnetic block 19 and the strong magnetic block 20. When the matching magnetic component 14 is installed in the lower vibration isolation cavity 18, the lower magnetic block 19 and the strong magnetic block 20 will generate an upward repulsive force on the matching magnetic component 14, causing the matching magnetic component 14 to drive the water spray plate 6 into a suspended state. At this time, the water spray plate 6 does not contact the vibration isolation structure 12, effectively isolating the transmission of the vibration energy of the water spray plate 6 to the condenser shell 8.

[0114] According to one embodiment of this application, the lower magnetic block 19 is a lower annular magnetic block, and the lower part of the matching magnetic element 14 passes through the inner hole of the annular magnetic block.

[0115] The lower annular magnetic block is a ring-shaped magnetic block with an inner hole that serves as a through-hole for the matching magnetic component 14. The annular design makes the magnetic force distribution more uniform, which is beneficial for generating a stable and effective magnetic repulsion force.

[0116] The lower part of the matching magnetic component 14 is designed to match the shape of the inner hole of the lower annular magnetic block, so that it can be smoothly inserted into the inner hole. When the matching magnetic component 14 is installed in the inner hole of the lower annular magnetic block, its lower magnetic pole is the same as the magnetic pole of the lower annular magnetic block and the strong magnetic block 20. According to the principle of magnetism, like magnetic poles repel each other. The lower annular magnetic block and the strong magnetic block 20 together generate an upward repulsive force on the matching magnetic component 14, causing the matching magnetic component 14 to drive the water spray plate 6 into a suspended state.

[0117] According to one embodiment of this application, the vibration isolation structure 12 includes an upper vibration isolation unit 21. The upper vibration isolation unit 21 includes an upper mounting plate 22 and an upper non-magnetic cylinder 23. The upper mounting plate 22 is connected to at least one of the condenser housing 8 and the water spray assembly 3. The upper non-magnetic cylinder 23 is connected to the upper mounting plate 22. An upper vibration isolation cavity 24 is provided inside the upper non-magnetic cylinder 23. An upper magnetic block 25 is provided on the inner wall of the upper vibration isolation cavity 24. The upper part of the matching magnetic element 14 passes through the upper vibration isolation cavity 24. The magnetic poles of the upper part of the matching magnetic element 14 are the same as the magnetic poles of the upper magnetic block 25.

[0118] The upper part of the matching magnetic component 14 passes through the upper vibration isolation cavity 24, and its upper magnetic poles are the same as those of the upper magnetic block 25. According to the principle of magnetism, like magnetic poles repel each other. The upper magnetic block 25 and the strong magnetic block 20 together generate an upward repulsive force on the matching magnetic component 14, so that the water spray plate 6 can be stably suspended on the vibration isolation structure 12. This stable suspension state effectively isolates the vibration energy of the water spray plate 6 from the transmission to the condenser shell 8, and greatly reduces the noise generated by the spray liquid film 4 impacting the water spray plate 6 on the condenser.

[0119] The upper mounting plate 22 is connected to at least one of the condenser housing 8 and the water spray assembly 3. This connection method allows for some flexibility in the installation position of the upper vibration isolation unit 21. A suitable connection position can be selected according to actual needs to optimize the vibration isolation effect.

[0120] According to one embodiment of this application, the upper non-magnetic straight cylinder 23 is one of a copper straight cylinder, a stainless steel straight cylinder, or a titanium alloy straight cylinder.

[0121] The upper non-magnetic straight cylinder 23 provides space for the installation and movement of the matching magnetic component 14, while avoiding interference with the magnetic effect itself. The upper non-magnetic straight cylinder 23 is connected to the upper mounting plate 22, and the connection method can be welding, bolting, etc., to ensure the firmness and stability of the connection.

[0122] The upper non-magnetic straight cylinder 23 has an upper vibration isolation cavity 24 inside. The inner wall of the upper vibration isolation cavity 24 is provided with upper magnetic blocks 25, and the bottom of the upper vibration isolation cavity 24 is provided with strong magnetic blocks 20. Both the upper magnetic blocks 25 and the strong magnetic blocks 20 are made of high-performance magnetic materials and have high magnetic strength. The upper magnetic blocks 25 are evenly distributed on the inner wall of the upper vibration isolation cavity 24, forming a strong magnetic repulsive force field together with the strong magnetic blocks 20.

[0123] The upper part of the matching magnetic component 14 passes through the upper vibration isolation cavity 24, and the magnetic poles of the upper part of the matching magnetic component 14 are the same as those of the upper magnetic block 25 and the strong magnetic block 20. When the matching magnetic component 14 is installed in the upper vibration isolation cavity 24, the upper magnetic block 25 and the strong magnetic block 20 will generate an upward repulsive force on the matching magnetic component 14, causing the matching magnetic component 14 to drive the water spray plate 6 into a suspended state. At this time, the water spray plate 6 does not contact the vibration isolation structure 12, effectively isolating the transmission of the vibration energy of the water spray plate 6 to the condenser shell 8.

[0124] According to one embodiment of this application, the upper magnetic block 25 is an upper annular magnetic block, and the upper part of the matching magnetic element 14 passes through the inner hole of the annular magnetic block.

[0125] The upper annular magnetic block is a magnetic block in the shape of a ring, and its inner hole is a through-hole for the upper part of the matching magnetic component 14. The annular design makes the magnetic force distribution more uniform, which is conducive to generating a stable and effective magnetic repulsion force.

[0126] The upper part of the matching magnetic component 14 is designed to match the shape of the inner hole of the upper annular magnetic block, so that it can be smoothly inserted into the inner hole. When the matching magnetic component 14 is installed in the inner hole of the upper annular magnetic block, its upper magnetic pole is the same as the magnetic pole of the upper annular magnetic block and the strong magnetic block 20. According to the principle of magnetism, like magnetic poles repel each other. The upper annular magnetic block and the strong magnetic block 20 together generate an upward repulsive force on the matching magnetic component 14, so that the matching magnetic component 14 drives the water spray plate 6 to be in a suspended state.

[0127] According to one embodiment of this application, there are two vibration isolation structures 12, one vibration isolation structure 12 is disposed on the condenser shell 8, and the other vibration isolation structure 12 is disposed on the water spray assembly 3. Matching magnetic components 14 are disposed on both sides of the water spray plate 6 corresponding to the vibration isolation structures 12.

[0128] As the core component of the condenser, the condenser housing 8 is susceptible to vibrations, both internally and externally, which can affect the water distribution plate 6. By installing a vibration isolation structure 12 on the condenser housing 8, these vibrational energies can be effectively prevented from being transmitted to the water distribution plate 6.

[0129] Another vibration isolation structure 12 is installed on the water spray assembly 3. During operation, the water spray assembly 3 will generate certain vibrations due to the spraying and flow of liquid. These vibrations may be transmitted to the water distribution plate 6 through the connecting parts, affecting the stability of the liquid film 4 and the condensation effect. By installing the vibration isolation structure 12 on the water spray assembly 3, this vibration can be effectively isolated, ensuring the normal operation of the water distribution plate 6. The design of the vibration isolation structure 12 installed on the water spray assembly 3 is similar to that of the vibration isolation structure 12 installed on the condenser housing 8, but it can be appropriately adjusted and optimized according to the specific structure and characteristics of the water spray assembly 3.

[0130] Matching magnetic components 14 and vibration isolation structures 12 are positioned on both sides of the water spray plate 6. This symmetrical arrangement ensures that the water spray plate 6 experiences uniform magnetic repulsion in both directions, maintaining a stable suspension state. When the condenser is running, the water spray assembly 3 sprays liquid into the condenser, forming a liquid film 4. The liquid film 4 impacts the water spray plate 6, causing vibration. However, due to the interaction between the matching magnetic components 14 and the vibration isolation structure 12, the water spray plate 6 does not transfer vibration energy to the condenser shell 8 and the water spray assembly 3, remaining in a stable suspension state, effectively reducing noise generation.

[0131] The dual vibration isolation structure 12 in this embodiment provides an effective solution for vibration isolation of the condenser. By setting vibration isolation structures 12 on the condenser housing 8 and the water spray assembly 3 respectively, and using symmetrically arranged matching magnetic components 14, all-round vibration isolation of the water spray plate 6 is achieved, improving the performance and reliability of the condenser and reducing noise.

[0132] According to one embodiment of this application, the water spray assembly 3 includes an air extraction device 11 and a water spray body. The water spray body is provided with a nozzle 5, and the outer shell and inner wall of the air extraction device 11 are parallel.

[0133] The air extraction device 11 provides the necessary conditions for the water spraying process by generating negative pressure. The water spray body is the core part of the water spray assembly 3, and it contains channels and devices for storing liquid, transporting liquid, and controlling liquid spraying. The nozzle 5 is installed on the water spray body.

[0134] The low-noise direct-mix condenser of this application is described below with reference to a specific embodiment.

[0135] First, the water spray plate 6 of the mixing condenser is connected to the wall of the extraction device 11 below the condenser shell and the water spray assembly 3 using a vibration isolation structure 12. The vibration isolation structure 12 consists of several upper and lower vibration isolation units. The lower vibration isolation unit 15 consists of a lower mounting plate 16 and a lower non-magnetic straight cylinder 17. The material of the lower non-magnetic straight cylinder 17 can be non-magnetic metal materials such as copper, stainless steel, and titanium alloy. The upper part of the inner wall of the lower non-magnetic straight cylinder 17 is provided with a lower magnetic block 19, and the bottom is provided with a strong magnetic block 20. The upper vibration isolation unit 21 consists of an upper mounting plate 22 and an upper non-magnetic straight cylinder 23.

[0136] The upper non-magnetic straight cylinder 23 can be made of non-magnetic metal materials such as copper, stainless steel, and titanium alloy, and an upper magnetic block 25 is provided on the lower part of the inner wall of the upper non-magnetic straight cylinder 23.

[0137] The water-spraying plate 6 has several small holes, and several bar magnets are installed at both ends of the water-spraying plate 6. Each bar magnet corresponds to a vibration isolation unit. The bar magnets are divided into N poles and S poles. All the magnets in the vibration isolation structure 12 have the same magnetic poles on their opposite sides. Taking the figure as an example: Assuming that the S pole is on top and the N pole is on the bottom, the side of the lower magnetic block 19 facing the N pole of the bar magnet is also set as the N pole. Similarly, the side of the upper magnetic block 25 facing the S pole of the bar magnet is also set as the S pole. The side of the strong magnetic block 20 at the bottom of the lower non-magnetic straight cylinder 17 facing the N pole of the bar magnet is also set as the N pole.

[0138] Under the repulsive force of like poles repelling magnets, the bar magnet on the water spray plate 6 will be in a suspended state, and under the repulsive force of the upper and lower magnetic blocks, it will not come into contact with the upper mounting plate 22 and the lower mounting plate 16, thereby completely isolating the water spray plate 6 and the bar magnet from the condenser shell, with no contact point, effectively isolating the transmission path of the vibration energy of the water spray plate 6 to the condenser shell.

[0139] All vibration isolation units are arranged at the gaps in the liquid film 4. When the liquid film 4 falls from above, it will not impact the vibration isolation units, but only the water spray plate 6. When the liquid film 4 falls and impacts the water spray plate 6, the water spray plate 6 will move downward under the impact force. According to the principle of electromagnetic induction, when a magnet moves in a non-magnetic metal tube such as a copper tube, an induced current will be generated in the non-magnetic metal tube. The induced current will generate an induced magnetic field. The additional induced magnetic field will exert an additional force on the moving magnet, thus reducing the speed of the magnet. Therefore, when the water spray plate 6 moves downward, it will drive the bar magnet to move downward, and it will be subject to the additional resistance force generated by the principle of electromagnetic induction, which will greatly reduce its downward speed and reduce the energy of downward movement.

[0140] Similarly, for the upper non-magnetic straight cylinder 23, an additional electromagnetic induction resistance force will be generated to hinder the downward movement of the bar magnet. Together with the resistance force generated by the lower non-magnetic straight cylinder 17, they will jointly hinder the downward movement of the bar magnet, thus slowing down its downward movement speed even more.

[0141] Furthermore, the strong magnetic block 20 at the bottom of the lower non-magnetic cylinder 17 also generates a repulsive force on the bar magnet. As the bar magnet continues to move downwards, the repulsive force increases, eventually causing the bar magnet and the water spray plate 6 to stop moving downwards, achieving a balance between the impact force and the repulsive force of the liquid film 4. The water spray plate 6 is suspended in another position but does not contact the lower non-magnetic cylinder 17, thus greatly weakening or even eliminating the vibration generated by the liquid film 4 impacting the water spray plate 6, achieving the vibration isolation effect of the water spray plate 6. The purpose of setting up two layers of non-magnetic cylinders is to use the resistive force generated by the principle of electromagnetic induction to greatly slow down the downward speed of the water spray plate 6, preventing it from suddenly impacting the mounting plate under the impact force of the liquid film 4. It also provides a buffer time for the strong magnetic block 20 at the bottom to generate a repulsive force, ensuring that the water spray plate 6 is in a suspended state from multiple directions.

[0142] The low-noise direct-mix condenser proposed according to the embodiments of this application includes a low-noise deaerator 50. Please refer to... Figures 7 to 9 It includes an outer component 100 and an inner component 200. The outer component 100 is hollow inside. The inner component 200 is located inside the outer component 100. A steam main channel 101 is formed between the inner component 200 and the outer component 100. The inner component 200 is provided with a deoxygenated liquid chamber 201. The inner component 200 is provided with a steam diversion channel 210 and an immersion channel 220. The steam diversion channel 210 connects the steam main channel 101 and the deoxygenated liquid chamber 201. The immersion channel 220 connects the deoxygenated liquid chamber 201.

[0143] According to the deoxygenation device 50 of the present application embodiment, the liquid in the deoxygenation liquid chamber 201 can enter the immersion channel 220. The liquid entering the immersion channel 220 is suitable for indirect heat exchange with the steam in the steam diversion channel 210, which reduces the direct contact between steam and water, thereby reducing the noise of bubbling deoxygenation to a certain extent.

[0144] It is understood that the outer component 100 is the outer structure of the deaerator 50, and the inner component 200 is located inside the outer component 100. It cooperates with the outer component 100 to form a main steam flow channel 101, which is the main path for steam flow, allowing steam to flow quickly and smoothly. Simultaneously, the inner component 200 contains a deaerator liquid chamber 201. The liquid in the deaerator liquid chamber 201 can enter the immersion channel 220 and exchange heat with the steam in the steam diversion channel 210. The steam diversion channel 210 connects the main steam flow channel 101 and the deaerator liquid chamber 201. Its function is to rationally divert the steam in the main steam flow channel 101 into the deaerator liquid chamber 201, thereby heating the liquid through steam bubbling.

[0145] The deaerator 50 of this application reduces the direct contact between steam and water, avoiding the generation of a large number of bubbles and violent physical collisions caused by direct steam impact on the liquid, thereby reducing the noise generated during the bubbling deaeration process to a certain extent. In traditional bubbling deaeration methods where steam and water directly contact each other, a large number of bubbles are generated when the steam impacts the liquid, and the bursting of these bubbles produces significant noise. However, this device uses indirect heat exchange, which reduces the occurrence of this situation, thereby reducing noise.

[0146] Understandably, the liquid in the deoxygenated liquid chamber 201 can enter the immersion channel 220. The liquid entering the immersion channel 220 is suitable for indirect heat exchange with the steam in the steam distribution channel 210. The liquid in the immersion channel 220 can absorb the heat from the steam in the steam distribution channel 210, achieving a temperature gradient increase in the liquid. This process effectively reduces the superheat difference between the steam and the liquid in the deoxygenated liquid chamber 201. Most of the steam completes the condensation process inside the steam distribution channel 210, and at least part of the steam completes the gas-liquid phase change within the steam distribution channel 210, avoiding direct impact between the steam and the liquid in the deoxygenated liquid chamber. This significantly reduces the noise source caused by rapid bubble collapse due to direct contact between the steam and the liquid. The porous structure (several branch pipes mentioned later) in the steam distribution channel 210 can enhance the dispersed condensation of steam, reduce the collapse intensity of bubbles formed by steam condensation, and absorb noise energy through the pore damping effect of the porous structure. The sound waves of residual bubble collapse undergo multiple reflections and attenuation in the tortuous path of the channel, achieving multi-dimensional noise reduction.

[0147] According to one embodiment of this application, each steam diversion channel 210 includes a main channel 211 and several branch channels 212. The main channel 211 is provided with a steam inlet 213, which is connected to the main steam channel 101. The branch channels 212 are connected to the main channel 211, and the branch channels 212 are provided with a steam outlet 214, which is connected to the deoxygenated liquid chamber 201.

[0148] By setting up a main flow channel 211 and several branch flow channels 212, steam can enter the deoxygenated liquid chamber 201 from the main steam channel 101 through the main flow channel 211 and then through the multiple branch flow channels 212. The multiple branch flow channels 212 increase the contact area between the steam and the liquid in the deoxygenated liquid chamber 201, allowing the steam to exchange heat with the liquid more fully. At the same time, the multiple branch flow channels 212 increase the flow path of the steam, making the heat exchange between the steam distribution channel 210 and the immersion channel 220 more complete.

[0149] It should be noted that, Figure 8 yes Figure 7 A schematic cross-sectional view of the structure at point AA in the first direction provided in the embodiment. Figure 9 yes Figure 7A schematic cross-sectional view of the structure at point AA in the second direction provided in the embodiment. The first direction and the second direction are opposite.

[0150] According to one embodiment of this application, the area of ​​the steam inlet 213 of each steam diversion channel 210 is greater than or equal to the sum of the areas of a plurality of steam outlets 214.

[0151] According to one embodiment of this application, the tributary pipe 212 includes N-level tributary pipes (N≥2), wherein:

[0152] The first-level tributary pipe is connected to the main pipe 211, and the first-level tributary pipe is equipped with a steam inlet 213 at its starting end.

[0153] The k-th tributary (2≤k≤N) branches off from the previous tributary 212.

[0154] The Nth-level branch pipe is connected to the deoxygenated liquid chamber 201, and the end of the Nth-level branch pipe is provided with a steam outlet 214.

[0155] In this embodiment, the branch pipes 212 are divided according to a certain hierarchical relationship, with at least two levels. Each level of branch pipe 212 undertakes different tasks in the steam transportation and distribution process. Through multi-level settings, more refined steam distribution is achieved. The first-level branch pipe is directly connected to the main pipe 211 and is the starting point for steam to enter the branch pipe 212 system from the main pipe 211. Starting from the first level, each branch pipe 212 branches out from the previous level. This branching extension allows the steam to be continuously subdivided, increasing the contact area between the steam and the liquid in the deoxygenated liquid chamber 201 and improving heat exchange efficiency. The Nth-level branch pipe is the last level of the branch pipe 212 system. It is directly connected to the deoxygenated liquid chamber 201 and has a steam outlet 214 at its end.

[0156] The multi-branch pipes 212 increase the contact area between the steam and the liquid in the deoxygenation chamber 201. As the steam passes through each branch pipe 212, it exchanges heat with the surrounding liquid. With the continuous branching and extension of the steam, more liquid can come into contact with the steam, accelerating the heat transfer rate and enabling the liquid to reach the temperature required for deoxygenation more quickly, thus improving the heat exchange efficiency.

[0157] In one embodiment, the tributary 212 is a secondary tributary, having a first-level tributary and a second-level tributary.

[0158] According to one embodiment of this application, each immersion channel 220 is provided with at least two liquid inlets 221. The liquid inlets 221 are the entry points for liquid into the immersion channel 220. Providing at least two liquid inlets 221 means that liquid can enter the immersion channel 220 from multiple different locations. The distribution of the liquid inlets 221 at their different locations allows liquid to enter more uniformly from the deoxygenated liquid chamber 201 and fill the channel space.

[0159] According to one embodiment of this application, a plurality of steam diversion channels 210 are distributed circumferentially along the inner layer component 200, and / or, immersion channels 220 are distributed circumferentially along the inner layer component 200.

[0160] When several steam distribution channels 210 are distributed circumferentially along the inner layer component 200, and / or immersion channels 220 are distributed circumferentially along the inner layer component 200, uniform distribution of steam and liquid within the device can be achieved. This uniform distribution allows steam and liquid to come into more sufficient contact with other components or media within the device, thereby improving heat exchange efficiency.

[0161] According to one embodiment of this application, the inner layer component 200 is provided with a plurality of steam diversion channels 210 and immersion channels 220 along its longitudinal extension direction, wherein the steam diversion channels 210 and immersion channels 220 are arranged alternately, and adjacent immersion channels 220 are interconnected by a transverse connecting channel 230.

[0162] The inner component 200 is provided with multiple steam diversion channels 210 and immersion channels 220 along its longitudinal extension direction, and the two are arranged alternately. This layout allows steam and liquid to be evenly distributed within the device. Adjacent immersion channels 220 are interconnected by transverse connecting channels 230, further promoting fluid mixing and flow. When steam enters the device through the steam diversion channels 210, it can fully engage in indirect heat exchange contact with the liquid in each immersion channel 220, achieving efficient heat exchange.

[0163] According to one embodiment of this application, the main steam channel 101 is an annular channel.

[0164] The annular channel structure allows steam to be evenly distributed along the annular path as it flows within the channel. Due to the symmetry of the annular channel, the flow resistance of steam in all directions is relatively balanced, thus allowing steam to enter the deoxygenated liquid chamber 201 more evenly through the steam diversion channel 210.

[0165] According to one embodiment of this application, the low-noise deaerator 50 includes a check mechanism disposed on the steam diversion channel 210. The check mechanism is configured to: allow fluid to flow unidirectionally from the steam main channel 101 to the steam diversion channel 210 when the fluid pressure in the main steam channel 101 is greater than that in the main steam channel 210; and block the reverse flow of fluid from the steam diversion channel 210 to the main steam channel 101 when the fluid pressure in the diversion channel 210 is greater than that in the main steam channel 101.

[0166] It is understandable that by setting a check valve, liquid can be prevented from flowing back into the main steam channel 101. When steam enters the main steam channel 101, steam will not come into direct contact with liquid in the main steam channel 101, thus avoiding direct noise generation.

[0167] According to one embodiment of this application, the check mechanism is implemented using a check valve structure, and the opening and closing direction of the valve core of the check valve is consistent with the flow direction from the main steam channel 101 to the steam diversion channel 210.

[0168] In one embodiment, the low-noise deaerator 50 includes a second check mechanism, which may be located at the steam outlet 214. The second check mechanism is configured to: allow fluid to flow unidirectionally from the steam diversion channel 210 to the deaerator liquid chamber 201 when the fluid pressure in the steam diversion channel 210 is greater than that in the deaerator liquid chamber 201; and block the reverse flow of fluid from the deaerator liquid chamber 201 to the steam diversion channel 210 when the fluid pressure in the deaerator liquid chamber 201 is greater than that in the steam diversion channel 210.

[0169] Understandably, the second check valve prevents the liquid in the deoxygenated liquid chamber 201 from flowing back into the steam diversion channel 210. When steam enters the main steam channel 101, there will be no direct contact between steam and liquid in the steam diversion channel 210, thus avoiding direct noise generation.

[0170] According to one embodiment of this application, the second check mechanism can be implemented using a diaphragm check valve, wherein the opening and closing direction of the diaphragm check valve core is consistent with the flow direction from the steam diversion channel 210 to the deoxygenated liquid chamber 201.

[0171] The low-noise deoxygenation device 50 of this application is described below with reference to a specific embodiment. The deoxygenation device 50 can be divided into two annular structures (outer layer component 100 and inner layer component 200). The annular space between the outer layer component 100 and the inner layer component 200 serves as the main steam channel 101 for bubbling. The inner layer component 200 is prepared by 3D printing and has a tree-like fractal microchannel structure (steam diversion channel 210) and an immersion channel 220. After the main steam passes through the steam diversion channel 210, the deoxygenation steam can be uniformly and finely ejected from the steam outlet 214 hole of the steam diversion channel 210, thereby heating the water in the central deoxygenation liquid chamber 201, raising the water temperature, reducing the subcooling, and thus reducing the oxygen content. Moreover, the tree-like fractal microchannel structure has low resistance, which can reduce the flow resistance of steam. The steam diversion channel 210 is the flow channel for the steam used for bubbling, and the immersion channel 220 is the immersion flow channel for the fluid.

[0172] In the steam diversion channel 210, steam enters the tree-like fractal microchannel structure from the steam inlet 213 through the main steam channel 101, and then flows to the steam outlet 214, achieving bubbling deoxygenation on the steam side. Meanwhile, in the immersion channel 220, water from the deoxygenation liquid chamber 201 enters the immersion channel 220 through the liquid inlet 221 formed by the micropores of the inner component 200. In the immersion channel 220, it undergoes indirect heat exchange with the steam in the steam diversion channel 210, thereby improving the liquid's heating performance and reducing the need for direct bubbling heating through steam and water contact, thus reducing bubbling deoxygenation noise to some extent. The two adjacent immersion flow channels... There are channels connecting them, allowing water to flow between different immersion-type flow channels. At the same time, due to the micro-channel porous structure of the inner component 200, it has the function of sound absorption and noise reduction. When the steam ejected from the steam outlet 214 of the inner component 200 comes into direct contact with the water in the deoxygenated liquid chamber 201 for heat exchange, the vibration noise generated by the steam collapse will be greatly absorbed and weakened by the micro-channel porous structure of the inner component 200 as it propagates to the surrounding area, achieving a good noise reduction effect. In addition, due to the condensation of the bubbling steam after contact with the water, and the heated flow of the water after heating, the water in the deoxygenated liquid chamber 201 will be automatically driven to be discharged to the deaerator outlet.

[0173] A low-noise direct-mix condenser according to a second aspect of this application includes a condenser housing 8 and the aforementioned deoxygenation device 50. The condenser housing 8 has a condensation chamber 2 inside. The aforementioned deoxygenation device 50 is disposed in the condensation chamber 2, and the deoxygenated liquid chamber 201 is connected to the condensation chamber 2.

[0174] A condenser is a device used to cool and convert gas or vapor into liquid, and it is widely used in industrial production, energy conversion, and other fields. The condenser housing 8 is the external structure of the condenser, providing protection and support for the internal components. It possesses a certain strength and sealing performance to contain and isolate the internal fluid. The deoxygenation device 50 is used to remove dissolved oxygen from the fluid (such as water).

[0175] Understandably, the liquid in the deoxygenated liquid chamber 201 can enter the immersion channel 220. The liquid entering the immersion channel 220 is suitable for indirect heat exchange with the steam in the steam distribution channel 210. The liquid in the immersion channel 220 can absorb the heat from the steam in the steam distribution channel 210, achieving a temperature gradient increase in the liquid. This process effectively reduces the superheat difference between the steam and the liquid in the deoxygenated liquid chamber. Most of the steam completes the condensation process inside the steam distribution channel 210, and at least part of the steam completes the gas-liquid phase change within the steam distribution channel 210, avoiding direct impact between the steam and the liquid in the deoxygenated liquid chamber. This significantly reduces the noise source caused by rapid bubble collapse due to direct contact between the steam and the liquid. The porous structure (several branch pipes) set in the steam distribution channel 210 can enhance the dispersed condensation of steam, reduce the collapse intensity of bubbles formed by steam condensation, and absorb noise energy through the pore damping effect of the porous structure. The sound waves of residual bubble collapse undergo multiple reflections and attenuation in the tortuous path of the channel, achieving multi-dimensional noise reduction.

[0176] It should be noted that the low-noise direct-mix condenser of this application has all the technical effects of the aforementioned deoxygenation device 50 since it includes the deoxygenation device 50, which will not be repeated here.

[0177] According to one embodiment of this application, a low-noise direct-mix condenser includes a porous grid rectifier structure 60, which is disposed at the outlet of the deoxygenated liquid chamber 201.

[0178] The porous grid rectifier structure 60 is a grid-like structure composed of multiple holes. It divides and guides the fluid through the holes and further absorbs excess noise energy through the porous structure.

[0179] A low-noise direct-mix condenser according to an embodiment of this application includes a deaeration device 50. Please refer to [reference needed]. Figures 10 to 12 The deoxygenation device 50 includes an outer component 100 and an inner component 200. The outer component 100 is hollow inside. The inner component 200 is located inside the outer component 100. The hollow interior of the inner component forms a steam mainstream channel 101. A deoxygenation liquid chamber 201 is formed between the inner component 200 and the outer component 100. The inner component 200 is provided with a steam diversion channel 210 and an immersion channel 220. The steam diversion channel 210 connects the steam mainstream channel 101 and the deoxygenation liquid chamber 201, and the immersion channel 220 connects the deoxygenation liquid chamber 201.

[0180] According to the deoxygenation device 50 of the present application embodiment, the liquid in the deoxygenation liquid chamber 201 can enter the immersion channel 220. The liquid entering the immersion channel 220 is suitable for indirect heat exchange with the steam in the steam diversion channel 210, which reduces the direct contact between steam and water, thereby reducing the noise of bubbling deoxygenation to a certain extent.

[0181] It is understood that the outer component 100 is the outer structure of the deoxygenation device 50, and the inner component 200 is located inside the outer component 100. The inner component 200 and the outer component 100 form a deoxygenated liquid chamber 201. The main steam flow channel 101 is the main path for steam flow, allowing steam to flow quickly and smoothly. The liquid in the deoxygenated liquid chamber 201 can enter the immersion channel 220 and exchange heat with the steam in the steam diversion channel 210. The steam diversion channel 210 connects the main steam flow channel 101 and the deoxygenated liquid chamber 201. Its function is to rationally divert the steam in the main steam flow channel 101 into the deoxygenated liquid chamber 201, thereby heating the liquid through steam bubbling.

[0182] The deaerator 50 of this application reduces the direct contact between steam and water, avoiding the generation of a large number of bubbles and violent physical collisions caused by direct steam impact on the liquid, thereby reducing the noise generated during the bubbling deaeration process to a certain extent. In traditional bubbling deaeration methods where steam and water directly contact each other, a large number of bubbles are generated when the steam impacts the liquid, and the bursting of these bubbles produces significant noise. However, this device uses indirect heat exchange, which reduces the occurrence of this situation, thereby reducing noise.

[0183] It is understandable that the steam diversion channel and immersion channel can form a porous structure in the inner components, which can realize the micro-distribution of steam, making the steam bubbles smaller when the steam comes into direct contact with water, thereby making the noise when the steam bubbles condense and collapse lower or become higher frequency noise that is easier to eliminate.

[0184] Understandably, the liquid in the deoxygenated liquid chamber 201 can enter the immersion channel 220. The liquid entering the immersion channel 220 is suitable for indirect heat exchange with the steam in the steam distribution channel 210. The liquid in the immersion channel 220 can absorb the heat of the steam in the steam distribution channel 210, achieving a temperature gradient increase in the liquid. This process effectively reduces the superheat difference between the steam and the liquid in the deoxygenated liquid chamber 201. Most of the steam completes the condensation process inside the steam distribution channel 210, and at least part of the steam completes the gas-liquid phase change within the steam distribution channel 210, avoiding direct impact between the steam and the liquid in the deoxygenated liquid chamber. This significantly reduces the noise source caused by rapid bubble collapse due to direct contact between the steam and the liquid. The porous structure (several branch pipes mentioned later) in the steam distribution channel 210 can enhance the dispersed condensation of steam, reduce the collapse intensity of bubbles formed by steam condensation, and absorb noise energy through the pore damping effect of the porous structure. The sound waves of residual bubble collapse undergo multiple reflections and attenuation in the tortuous path of the channel, achieving multi-dimensional noise reduction.

[0185] It should be noted that, Figure 11 yes Figure 10 A schematic cross-sectional view of the structure at BB in the first direction provided in the embodiment. Figure 12 yes Figure 10 A schematic cross-sectional view of the structure at BB in the second direction provided in the embodiment. The first direction and the second direction are opposite.

[0186] According to one embodiment of this application (not shown in the figure), each steam diversion channel 210 includes a main channel 211 and several branch channels 212. The main channel 211 is provided with a steam inlet 213, which is connected to the main steam channel 101. The branch channels 212 are connected to the main channel 211, and the branch channels 212 are provided with a steam outlet 214, which is connected to the deoxygenated liquid chamber 201.

[0187] By setting up a main flow channel 211 and several branch flow channels 212, steam can enter the deoxygenated liquid chamber 201 from the main steam channel 101 through the main flow channel 211 and then through the multiple branch flow channels 212. The multiple branch flow channels 212 increase the contact area between the steam and the liquid in the deoxygenated liquid chamber 201, allowing the steam to exchange heat with the liquid more fully. At the same time, the multiple branch flow channels 212 increase the flow path of the steam, making the heat exchange between the steam distribution channel 210 and the immersion channel 220 more complete.

[0188] It should be noted that, in this embodiment, the main flow pipe 211 is located near the main steam channel 10, while the branch pipe 212 is located on the side near the deoxygenated liquid chamber 201. However, in actual use, the positions of the main flow pipe 211 and the branch pipe 212 can be interchanged.

[0189] According to one embodiment of this application, the area of ​​the steam inlet 213 of each steam diversion channel 210 is greater than or equal to the sum of the areas of a plurality of steam outlets 214.

[0190] According to one embodiment of this application, the outer component is provided with a porous media layer. The porous media layer has excellent sound absorption and noise reduction properties. When steam and water come into direct contact and condense, the resulting vibration noise is largely absorbed by the porous media layer, thereby reducing the energy transmitted outward from the vibration noise and achieving the purpose of low-noise bubbling deoxygenation.

[0191] According to one embodiment of this application, the tributary pipe 212 includes N-level tributary pipes (N≥2), wherein:

[0192] The first-level tributary pipe is connected to the main pipe 211, and the first-level tributary pipe is equipped with a steam inlet 213 at its starting end.

[0193] The k-th tributary (2≤k≤N) branches off from the previous tributary 212.

[0194] The Nth-level branch pipe is connected to the deoxygenated liquid chamber 201, and the end of the Nth-level branch pipe is provided with a steam outlet 214.

[0195] In this embodiment, the branch pipes 212 are divided according to a certain hierarchical relationship, with at least two levels. Each level of branch pipe 212 undertakes different tasks in the steam transportation and distribution process. Through multi-level settings, more refined steam distribution is achieved. The first-level branch pipe is directly connected to the main pipe 211 and is the starting point for steam to enter the branch pipe 212 system from the main pipe 211. Starting from the first level, each branch pipe 212 branches out from the previous level. This branching extension allows the steam to be continuously subdivided, increasing the contact area between the steam and the liquid in the deoxygenated liquid chamber 201 and improving heat exchange efficiency. The Nth-level branch pipe is the last level of the branch pipe 212 system. It is directly connected to the deoxygenated liquid chamber 201 and has a steam outlet 214 at its end.

[0196] The multi-branch pipes 212 increase the contact area between the steam and the liquid in the deoxygenation chamber 201. As the steam passes through each branch pipe 212, it exchanges heat with the surrounding liquid. With the continuous branching and extension of the steam, more liquid can come into contact with the steam, accelerating the heat transfer rate and enabling the liquid to reach the temperature required for deoxygenation more quickly, thus improving the heat exchange efficiency.

[0197] In one embodiment, the tributary pipe 212 is a secondary tributary pipe, having a first-level tributary pipe and a second-level tributary pipe.

[0198] According to one embodiment of this application, each immersion channel 220 is provided with at least two liquid inlets 221. The liquid inlets 221 are the entry points for liquid into the immersion channel 220. Providing at least two liquid inlets 221 means that liquid can enter the immersion channel 220 from multiple different locations. The distribution of the liquid inlets 221 at their different locations allows liquid to enter more uniformly from the deoxygenated liquid chamber 201 and fill the channel space.

[0199] According to one embodiment of this application, a plurality of steam diversion channels 210 are distributed circumferentially along the inner layer component 200, and / or, immersion channels 220 are distributed circumferentially along the inner layer component 200.

[0200] When several steam distribution channels 210 are distributed circumferentially along the inner layer component 200, and / or immersion channels 220 are distributed circumferentially along the inner layer component 200, uniform distribution of steam and liquid within the device can be achieved. This uniform distribution allows steam and liquid to come into more sufficient contact with other components or media within the device, thereby improving heat exchange efficiency.

[0201] According to one embodiment of this application, the inner layer component 200 is provided with a plurality of steam diversion channels 210 and immersion channels 220 along its longitudinal extension direction, wherein the steam diversion channels 210 and immersion channels 220 are arranged alternately, and adjacent immersion channels 220 are interconnected by a transverse connecting channel 230.

[0202] The inner component 200 is provided with multiple steam diversion channels 210 and immersion channels 220 along its longitudinal extension direction, and the two are arranged alternately. This layout allows steam and liquid to be evenly distributed within the device. Adjacent immersion channels 220 are interconnected by transverse connecting channels 230, further promoting fluid mixing and flow. When steam enters the device through the steam diversion channels 210, it can fully engage in indirect heat exchange contact with the liquid in each immersion channel 220, achieving efficient heat exchange.

[0203] According to one embodiment of this application, the deoxygenated liquid chamber 201 is an annular cavity. The main steam channel 101 is a circular channel in the middle.

[0204] The circular channel structure allows for uniform distribution of steam as it flows within the main steam channel 101. Due to the symmetry of the circular channel, the flow resistance of steam in all directions is relatively balanced, thus allowing the steam to enter the deoxygenated liquid chamber 201 more evenly through the steam diversion channel 210.

[0205] According to one embodiment of this application, the low-noise deaerator 50 includes a check mechanism disposed on the steam diversion channel 210. The check mechanism is configured to: allow fluid to flow unidirectionally from the steam main channel 101 to the steam diversion channel 210 when the fluid pressure in the main steam channel 101 is greater than that in the main steam channel 210; and block the reverse flow of fluid from the steam diversion channel 210 to the main steam channel 101 when the fluid pressure in the diversion channel 210 is greater than that in the main steam channel 101.

[0206] It is understandable that by setting a check valve, liquid can be prevented from flowing back into the main steam channel 101. When steam enters the main steam channel 101, steam will not come into direct contact with liquid in the main steam channel 101, thus avoiding direct noise generation.

[0207] According to one embodiment of this application, the check mechanism is implemented using a check valve structure, and the opening and closing direction of the valve core of the check valve is consistent with the flow direction from the main steam channel 101 to the steam diversion channel 210.

[0208] In one embodiment, the low-noise deaerator 50 includes a second check mechanism, which may be located at the steam outlet 214. The second check mechanism is configured to: allow fluid to flow unidirectionally from the steam diversion channel 210 to the deaerator liquid chamber 201 when the fluid pressure in the steam diversion channel 210 is greater than that in the deaerator liquid chamber 201; and block the reverse flow of fluid from the deaerator liquid chamber 201 to the steam diversion channel 210 when the fluid pressure in the deaerator liquid chamber 201 is greater than that in the steam diversion channel 210.

[0209] Understandably, the second check valve prevents the liquid in the deoxygenated liquid chamber 201 from flowing back into the steam diversion channel 210. When steam enters the main steam channel 101, there will be no direct contact between steam and liquid in the steam diversion channel 210, thus avoiding direct noise generation.

[0210] According to one embodiment of this application, the second check mechanism can be implemented using a diaphragm check valve, wherein the opening and closing direction of the diaphragm check valve core is consistent with the flow direction from the steam diversion channel 210 to the deoxygenated liquid chamber 201.

[0211] The low-noise deoxygenation device 50 of this application is described below with reference to a specific embodiment. The deoxygenation device 50 can be divided into two annular structures (outer component 100 and inner component 200). The annular space between the outer component 100 and the inner component 200 serves as the deoxygenation liquid chamber 201. The interior of the inner component 200 forms the main steam channel 101 for bubbling. The inner component 200 is fabricated by 3D printing and has a tree-like fractal microchannel structure (steam diversion channel 210). After the mainstream steam passes through the steam diversion channel 210, the steam for deoxygenation can be evenly and finely ejected from the steam outlet 214 of the steam diversion channel 210, thereby heating the water in the central deoxygenation liquid chamber 201, raising the water temperature, reducing the subcooling, and thus reducing the oxygen content; and the dendritic fractal microchannel structure has low resistance, which can reduce the flow resistance of steam; the steam diversion channel 210 is the flow channel for the steam used for bubbling, and the immersion channel 220 is the immersion flow channel for the fluid;

[0212] In the steam diversion channel 210, steam enters the tree-like fractal microchannel structure from the steam inlet 213 through the main steam channel 101, and then flows to the steam outlet 214, achieving bubbling deoxygenation on the steam side. Meanwhile, in the immersion channel 220, water from the deoxygenation liquid chamber 201 enters the immersion channel 220 through the liquid inlet 221 formed by the micropores of the inner component 200. In the immersion channel 220, it undergoes indirect heat exchange with the steam in the steam diversion channel 210, thereby improving the liquid's heating performance and reducing the need for direct bubbling heating through steam and water contact, thus reducing bubbling deoxygenation noise to some extent. The two adjacent immersion flow channels... There are channels connecting them, allowing water to flow between different immersion-type flow channels. At the same time, due to the micro-channel porous structure of the inner component 200, it has the function of sound absorption and noise reduction. When the steam ejected from the steam outlet 214 of the inner component 200 comes into direct contact with the water in the deoxygenated liquid chamber 201 for heat exchange, the vibration noise generated by the steam collapse will be greatly absorbed and weakened by the micro-channel porous structure of the inner component 200 as it propagates to the surrounding area, achieving a good noise reduction effect. In addition, due to the condensation of the bubbling steam after contact with the water, and the heated flow of the water after heating, the water in the deoxygenated liquid chamber 201 will be automatically driven to be discharged to the deaerator outlet.

[0213] A low-noise direct-mix condenser according to a second aspect of this application includes a condenser housing 8 and the aforementioned deoxygenation device 50. The condenser housing 8 has a condensation chamber 2 inside. The aforementioned deoxygenation device 50 is disposed in the condensation chamber 2, and the deoxygenated liquid chamber 201 is connected to the condensation chamber 2.

[0214] A condenser is a device used to cool and convert gas or vapor into liquid, and it is widely used in industrial production, energy conversion, and other fields. The condenser housing 8 is the external structure of the condenser, providing protection and support for the internal components. It possesses a certain strength and sealing performance to contain and isolate the internal fluid. The deoxygenation device 50 is used to remove dissolved oxygen from the fluid (such as water).

[0215] Understandably, the liquid in the deoxygenated liquid chamber 201 can enter the immersion channel 220. The liquid entering the immersion channel 220 is suitable for indirect heat exchange with the steam in the steam distribution channel 210. The liquid in the immersion channel 220 can absorb the heat from the steam in the steam distribution channel 210, achieving a temperature gradient increase in the liquid. This process effectively reduces the superheat difference between the steam and the liquid in the deoxygenated liquid chamber. Most of the steam completes the condensation process inside the steam distribution channel 210, and at least part of the steam completes the gas-liquid phase change within the steam distribution channel 210, avoiding direct impact between the steam and the liquid in the deoxygenated liquid chamber. This significantly reduces the noise source caused by rapid bubble collapse due to direct contact between the steam and the liquid. The porous structure (several branch pipes) set in the steam distribution channel 210 can enhance the dispersed condensation of steam, reduce the collapse intensity of bubbles formed by steam condensation, and absorb noise energy through the pore damping effect of the porous structure. The sound waves of residual bubble collapse undergo multiple reflections and attenuation in the tortuous path of the channel, achieving multi-dimensional noise reduction.

[0216] It should be noted that the condenser of this application has all the technical effects of the aforementioned low-noise deoxygenation device 50 because it includes the low-noise deoxygenation device 50, which will not be repeated here.

[0217] According to one embodiment of this application, a low-noise direct-mix condenser includes a low-resistance fractal structure 70, which is disposed at the outlet of the deoxygenated liquid chamber 201.

[0218] The low-resistivity fractal structure 70 is a grid-like structure composed of multiple holes. It divides and guides the fluid through the holes and further absorbs excess noise energy through the porous structure.

[0219] As the water is heated, oxygen is released from it and then flows out with the water from the liquid outlet of the low-noise deoxygenation device 50. The low-resistance fractal structure 70 effectively separates water and air, causing the air to rise and the water to fall. When both flow out from the liquid outlet of the low-noise deoxygenation device 50, the air, being at the top, can rise to the water surface more quickly and enter the condensation chamber 2. It is then extracted by the air ejector from the air ejector port 26, instead of being carried away by the water and extracted by the external water pump from the condensate outlet 27 at the bottom of the condenser. This reduces the risk of high vibration and noise caused by the external water pump drawing in the air-water mixture.

[0220] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
