Description

Technical Field

[0001] This invention relates to the field of generator protection technology, and in particular to a generator anti-salt spray device and a generator. Background Technology

[0002] Generators typically require a continuous intake of outside air for heat dissipation and ventilation during operation. In high-humidity, high-salt-spray environments, salt spray particles and aerosols carried in the air can easily enter the generator and deposit and crystallize on the stator windings, rotor core, insulation components, and other metal structures. This can lead to problems such as decreased insulation performance, metal corrosion, partial short circuits, and abnormal heating, and in severe cases, can affect the generator's stable operation and service life. Especially in applications such as ships that are constantly exposed to marine environments, the high salt spray concentration and long service life place even higher demands on generator air intake protection.

[0003] Existing salt spray protection solutions typically employ single filtration, inertial separation, or simple cyclone separation structures. While these can provide some protection against larger salt spray droplets, their effectiveness remains limited for smaller salt spray particles and ultrafine salt spray aerosols. Furthermore, existing porous adsorption materials tend to become saturated after prolonged use, lacking effective in-situ regeneration capabilities and often requiring shutdown for disassembly and replacement. This not only increases maintenance costs but also disrupts continuous equipment operation. In addition, if the separated salt solution is not promptly discharged, it can accumulate, backflow, or even be re-entrained by the airflow, causing secondary pollution. Under certain operating conditions, the internal channels of the air intake protection structure may become clogged due to salt crystal deposition, further affecting air intake efficiency and protection stability.

[0004] Therefore, there is an urgent need to provide a generator anti-salt spray device and generator with a reasonable structure, high separation efficiency, ability to classify salt spray of different particle sizes, and adsorption regeneration and salt discharge capabilities, so as to improve the problems of insufficient salt spray removal accuracy, easy saturation and failure of adsorption layer, and insufficient salt discharge treatment in the existing technology.

[0019] Exemplary embodiments of this application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are for teaching those skilled in the art how to implement this application only, and are not intended to exhaust all possible methods of this application, nor to limit the scope of this application.

[0020] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 3As shown, an embodiment of the present invention provides a generator anti-salt spray device, including a cylinder 2 and a salt discharge assembly 6. The cylinder 2 has an air inlet 1 at its inlet end and an air outlet 3 at its outlet end. Inside the cylinder 2, along the airflow direction, an interception assembly 7, a swirling assembly 9, and an adsorption assembly 11 are arranged sequentially. A first collection tank 8 is provided below the interception assembly 7 to receive the salt solution separated by the interception assembly 7, and a second collection tank 10 is provided below the swirling assembly 9 to receive the salt solution separated by the swirling assembly 9.

[0023] Specifically, the interception component 7 includes an interception disk 701, on which air vents 702 are provided for airflow. The vortex component 9 includes a rotatable shaft 901 and blades 902 disposed on the shaft 901. The adsorption component 11 includes a porous adsorption element 1102 and a capillary tube 12 communicating with the porous adsorption element 1102. The first collection tank 8 and the second collection tank 10 are both connected to the salt removal component 6.

[0024] like Figure 1 As shown, in this embodiment, the air outlet 3 is connected to the generator's air intake pipe. Preferably, the air outlet 3 is connected to the generator's air intake pipe via a connecting flange, so that the generator's anti-salt spray device can be installed at the generator's air intake end. When the generator's anti-salt spray device is working, outside air containing high salt spray enters the cylinder 2 through the air inlet 1.

[0025] Optionally, the air inlet 1 is a trumpet-shaped air inlet to allow outside air to enter the cylinder 2 more smoothly, thereby reducing air intake disturbance.

[0026] In some embodiments, see Figure 1 The air inlet 1 is also equipped with a filter screen 4 for pre-filtering the air entering the cylinder 2. Large solid particles such as sand and lint in the air are first intercepted by the filter screen 4 to prevent them from entering the rear structure and causing wear or blockage of the flow channel. The size of the filter screen 4 can be adjusted according to actual needs.

[0027] like Figure 3 As shown, the interception component 7 is disposed inside the cylinder 2 and located downstream of the filter screen 4. The interception component 7 includes at least two interception discs 701 spaced apart along the airflow direction. The interception discs 701 are used to block large salt spray droplets in the airflow, while the gas continues to flow downward through the vent holes 702 on the interception discs 701.

[0028] Preferably, the vents 702 on two adjacent sets of interceptor disks 701 can be staggered so that the airflow passes through different positions of the two adjacent sets of interceptor disks 701, thereby improving the interception capability of large salt spray droplets.

[0029] In some embodiments, the interceptor disk 701 may be configured in three or more forms to further extend the airflow path and improve the interception effect on large salt spray droplets.

[0030] Optionally, the upper surface of the interception disk 701 has an arc-shaped structure with the center convex upward and the edges relatively low, so that after the intercepted droplets fall on the surface of the interception disk 701, they flow to the outer peripheral edge and converge under the action of gravity, thus facilitating subsequent export and collection.

[0031] Furthermore, such as Figure 4 As shown, multiple vent holes 702 are spaced apart on the interceptor disk 701 to ensure airflow while reducing the possibility of droplets passing directly through the interceptor disk 701 with the airflow.

[0032] Optionally, such as Figure 4 As shown, the interception disk 701 is provided with multiple leak-proof sleeves 703, which are respectively located on the air inlet side of multiple vent holes 702 and correspond one-to-one with each vent hole 702. The leak-proof sleeves 703 protrude from the surface of the interception disk 701 in a direction away from the interception disk 701 and surround the periphery of the corresponding vent hole 702. By providing leak-proof sleeves 703, the possibility of droplets falling back through the vent holes 702 during the accumulation of droplets on the surface of the interception disk 701 can be reduced, thereby improving the interception disk 701's ability to retain brine.

[0033] Optionally, such as Figure 4 As shown, the air intake side of the interception plate 701 is provided with a wind deflector ring 704, which is located on the outer periphery of multiple leak-proof sleeves 703 and is spaced apart from the cylinder body 2. In addition, the wind deflector ring 704 has multiple liquid guiding notches 705 on the side facing the interception plate 701, and the multiple liquid guiding notches 705 are distributed circumferentially along the wind deflector ring 704.

[0034] By setting up the wind deflector ring 704, the droplets that gather at the edge of the interception disk 701 can be blocked, reducing the direct impact of the high-speed airflow on the droplets and thus reducing the possibility of the droplets being atomized again. At the same time, after the droplets gather at the edge of the interception disk 701, they can be discharged to the edge area through the liquid guiding notch 705 for subsequent collection.

[0035] In some embodiments, the outer edge of the interception disk 701 is provided with a plurality of drainage notches 706, which are distributed at intervals along the circumference of the interception disk 701. The drainage notches 706 are used to guide the droplets that converge at the edge of the interception disk 701 downward, so that the droplets leave the interception disk 701 and enter the first collection tank 8 below.

[0036] Preferably, see Figure 4The liquid guiding notch 705 and the liquid draining notch 706 can be set in a corresponding position in the circumferential direction so that after the droplets flow through the liquid guiding notch 705 to the edge of the intercepting disk 701, they are further discharged downward through the liquid draining notch 706.

[0037] It is understandable that after the intercepted brine falls onto the surface of the interception disk 701, it converges towards the outer edge under the guidance of the arc-shaped structure of the interception disk 701. During the convergence process, the leak-proof sleeve 703 can reduce the possibility of the droplets falling back through the vent hole 702; after reaching the edge, the windproof ring 704 can reduce the scouring of the droplets by the high-speed airflow, and the droplets are then discharged downwards through the liquid guiding notch 705 and the liquid draining notch 706.

[0038] Optionally, such as Figure 3 As shown, a flow guiding structure is provided on the inner wall of the cylinder 2, between the interception component 7 and the swirl component 9. The flow guiding structure is used to guide the airflow after the initial treatment by the interception component 7, so that the airflow forms a downward rotating flow state before entering the swirl component 9, thereby providing a basis for subsequent swirl separation.

[0039] In one embodiment, such as Figure 3 As shown, the flow guiding structure is specifically a flow guiding rib 201 provided on the inner wall of the cylinder 2. The flow guiding rib 201 can extend spirally along the cylinder 2 to guide the airflow and guide the airflow to form a downward rotating flow path along the inner wall of the cylinder 2.

[0040] See Figure 3 The swirl assembly 9 is located downstream of the guide structure and inside the cylinder 2. The swirl assembly 9 is used to further separate small salt spray droplets in the airflow, thereby improving the generator's salt spray protection device's ability to handle salt spray of different particle sizes. Through the cooperation between the guide structure and the swirl assembly 9, the airflow can be pre-swirled before entering the swirl assembly 9, which is beneficial for enhancing the subsequent swirl separation effect.

[0041] Specifically, such as Figure 5 As shown, the swirl assembly 9 includes a rotating shaft 901 rotatably disposed within the cylinder 2 and a plurality of blades 902 disposed on the rotating shaft 901. Preferably, the rotating shaft 901 is arranged along the axial direction of the cylinder 2 to serve as a support structure for the mounting and rotation of the plurality of blades 902. The plurality of blades 902 are distributed at circumferential intervals along the rotating shaft 901.

[0042] In some embodiments, the blade 902 may be configured as a curved or inclined plate structure to guide the airflow during rotation and enhance the rotational state of the airflow. When the airflow passes through the swirl assembly 9, it can drive the blade 902 to rotate around the axis 901, thereby utilizing the kinetic energy of the airflow itself to further enhance the swirl effect and make it easier for the small salt spray droplets remaining in the airflow to be thrown outward under centrifugal force.

[0043] like Figure 5 As shown, the second collection tank 10 is disposed below the swirling assembly 9 and is arranged coaxially with the swirling assembly 9. The second collection tank 10 is disposed around the outer periphery of the swirling assembly 9 and has an opening facing the swirling assembly 9 to receive droplets separated by the swirling assembly 9 and thrown to the outer periphery by the blades 902. With the above arrangement, the salt solution separated by the swirling assembly 9 can enter the second collection tank 10 after leaving the main airflow path, thereby achieving further collection of small particulate salt spray droplets.

[0044] Optionally, such as Figure 5 and Figure 6 As shown, the opening of the second collection tank 10 is provided with an anti-backflow structure to reduce the possibility that the salt solution collected in the second collection tank 10 will be rolled up by the airflow and re-enter the airflow channel.

[0045] Specifically, see Figure 5 The anti-backflow structure includes multiple anti-backflow plates 13, which are distributed circumferentially along the second collection tank 10 and are collectively located at the opening of the second collection tank 10 to shield the opening of the second collection tank 10.

[0046] Preferably, a plurality of anti-backflow plates 13 are arranged sequentially along the circumference of the second collection tank 10, with the edges of adjacent anti-backflow plates 13 closely attached to each other to form a continuous shielding of the opening of the second collection tank 10.

[0047] In other embodiments, the edges of adjacent anti-backflow plates 13 may also partially overlap, that is, the edges of adjacent anti-backflow plates 13 overlap each other to form a continuous shielding of the opening of the second collection tank 10 when no external force is applied; when the anti-backflow plates 13 are deformed by magnetic force, the overlapping parts may partially separate, thereby forming a liquid passage gap for the brine to pass through. In addition, while ensuring that the opening of the second collection tank 10 is shielded, the multiple anti-backflow plates 13 may also adopt other arrangement methods.

[0048] By setting multiple anti-backflow plates 13, the possibility of airflow directly acting on the brine in the second collection tank 10 can be reduced, thereby reducing the risk of the collected brine being rolled up again.

[0049] See Figure 6 An anti-backflow plate 13 is disposed at the opening of the second collection tank 10. The anti-backflow plate 13 includes a substrate 1301, a connecting plate 1302, and a second magnet 1303. The connecting plate 1302 is disposed at opposite ends of the substrate 1301 and connected to the inner wall of the cylinder 2 to provide support and limit the substrate 1301; the second magnet 1303 is disposed on the substrate 1301. Preferably, the second magnet 1303 is disposed on the surface of the substrate 1301 facing the blade 902.

[0050] Preferably, the substrate 1301 can be a sheet-like structure with elastic recovery capability, so that it can deform under external force and recover after the external force disappears. The connecting piece 1302 can be a rigid structure so that it can support and limit the substrate 1301 after being connected to the inner wall of the cylinder 2.

[0051] See Figure 5 In one embodiment, a first magnet 903 is provided at the outer end of the blade 902, and a second magnet 1303 is provided on the substrate 1301. The first magnet 903 and the second magnet 1303 are correspondingly arranged and can generate a magnetic interaction with the second magnet 1303. Thus, when the blade 902 rotates with the airflow, the first magnet 903 can periodically pass near the second magnet 1303, and the magnetic interaction causes the substrate 1301 to deform, forming a liquid passage gap at the opening of the second collection tank 10. When the first magnet 903 leaves the corresponding position, the substrate 1301 can return to its initial state and re-cover the opening of the second collection tank 10. Therefore, the anti-backflow plate 13 can periodically open and close during the operation of the swirl assembly 9.

[0052] For example, in this embodiment, the first magnet 903 and the second magnet 1303 are arranged opposite each other with the same pole. When the blade 902 rotates to the corresponding position, the first magnet 903 and the second magnet 1303 generate a magnetic repulsion, thereby causing the substrate 1301 to deform and causing the anti-backflow plate 13 to be displaced relative to the opening position of the second collection tank 10, thereby forming a liquid passage gap for the brine to pass through between the anti-backflow plates 13 and / or between the anti-backflow plates 13 and the second collection tank 10.

[0053] In other embodiments, the first magnet 903 and the second magnet 1303 can also be arranged with opposite poles. When the blade 902 rotates to the corresponding position, a magnetic attraction is generated between the two, thereby pulling the substrate 1301 to deform and forming a liquid passage gap for the salt solution to pass through.

[0054] In some embodiments, a connecting pipe is provided between the inlet end of the capillary 12 and the bottom of the second collecting tank 10, with one end of the connecting pipe communicating with the bottom of the second collecting tank 10 and the other end communicating with the inlet end of the capillary 12. Preferably, the connecting pipe can be arranged along the wall of the cylinder 2 or other concealed paths to reduce the impact on the airflow channel and to adapt to the installation space and relative positional relationship between different components.

[0055] like Figure 5 As shown, the adsorption component 11 is located downstream of the cyclone component 9 and is used to further purify the airflow after the pre-stage separation. The airflow after the two-stage separation by the interception component 7 and the cyclone component 9 continues to flow downward and enters the adsorption component 11 to further remove residual salt mist.

[0056] See Figure 7 The adsorption assembly 11 includes two fixing frames 1101, which are arranged at intervals along the airflow direction to support and limit the porous adsorption element 1102 located therebetween.

[0057] In some embodiments, such as Figure 7 As shown, the fixing frame 1101 can be a disc-shaped support structure with multiple hollow areas to take into account both support function and ventilation performance.

[0058] like Figure 7 As shown, the porous adsorbent 1102 is disposed between two fixing frames 1101 and is clamped and installed by the two fixing frames 1101. The porous adsorbent 1102 may be an adsorbent material layer with interconnected pores, so as to adsorb residual salt spray particles or salt spray aerosols therein when the airflow flows through it.

[0059] Preferably, the porous adsorbent 1102 has a connected pore network inside, thereby increasing the contact area between the airflow and the adsorbent material and improving the adsorption capacity for fine salt spray.

[0060] In some embodiments, the porous adsorbent 1102 may be made of a porous material with adsorption capacity, such as activated carbon, molecular sieve, silica gel, alumina, zeolite, porous ceramic or porous polymer, but is not limited to the above materials.

[0061] Optionally, see Figure 7 The capillary tube 12 is disposed within the porous adsorbent 1102 and communicates with the porous adsorbent 1102. Preferably, the capillary tube 12 extends along the circumferential or radial path of the porous adsorbent 1102 to increase the contact range with the porous adsorbent 1102 and facilitate the extraction of liquid from the porous adsorbent 1102.

[0062] In some embodiments, the capillary 12 may be arranged in a spiral coil to provide a longer liquid guiding path within a limited space and improve the ability to extract liquid from the interior of the porous adsorbent 1102.

[0063] Optionally, see Figure 8 The capillary 12 has multiple connecting holes 1201 on its wall, which are spaced apart along the extension direction of the capillary 12 and communicate with the interior of the porous adsorbent 1102. In this way, the liquid adsorbed in the porous adsorbent 1102 can enter the capillary 12 through the connecting holes 1201 and be discharged along the capillary 12, thereby mitigating the saturation failure of the porous adsorbent 1102. Thus, the capillary 12 not only serves as a liquid guiding structure but also forms a communication path with the porous adsorbent 1102, enabling continuous transfer of the adsorbed salt solution.

[0064] It is understood that in this embodiment, after the airflow undergoes the first two stages of separation, it enters the adsorption assembly 11. The fine salt mist particles or salt mist aerosols remaining in the airflow are further adsorbed as it flows through the porous adsorption element 1102, thereby achieving deep purification of the airflow. The clean air treated by the adsorption assembly 11 is finally output from the outlet 3 to the generator intake pipe.

[0065] During the adsorption process, the salt adsorbed in the porous adsorbent 1102 can gradually form a salt solution or a high-concentration salt solution; this liquid can enter the capillary 12 through the connecting hole 1201 and be discharged along the capillary 12 under capillary action or siphon action. This arrangement helps to slow down the saturation failure of the porous adsorbent 1102 and improve the continuous working capacity of the adsorption assembly 11.

[0066] In some embodiments, such as Figure 9 As shown, the inner cavity of the capillary 12 forms a liquid guiding channel 1202, which includes a constricted portion and a flared portion, which are alternately arranged along the liquid flow direction. This alternation allows for localized velocity variations as the brine flows within the liquid guiding channel 1202, thereby enhancing the capillary 12's ability to extract liquid and reducing the likelihood of long-term retention and crystallization of the brine inside the capillary 12.

[0067] It is understandable that the change in flow velocity generated when the salt solution flows in the liquid guiding channel 1202 can also improve the ability to transfer and export liquid in the porous adsorbent 1102 by combining the communication between the connecting hole 1201 and the porous adsorbent 1102, thereby helping to slow down the saturation failure of the porous adsorbent 1102.

[0068] In this way, the salt solution entering the second collection tank 10 can enter the capillary tube 12 through the connecting pipe at its bottom and continue to be discharged outwards. At the same time, the liquid adsorbed in the porous adsorbent 1102 can also enter the capillary tube 12 through the connecting hole 1201 and be discharged under capillary or siphon action. Therefore, it not only facilitates the discharge of salt solution in the second collection tank 10, but also helps to slow down the saturation failure and salt crystal deposition of the porous adsorbent 1102, and improves the continuous working capability of the generator anti-salt spray device.

[0069] like Figure 2 and Figure 10As shown, the sealing ring 5 is disposed between the air outlet 3 and the connecting flange of the generator intake pipe to seal the connection gap between the two. The sealing ring 5 includes an outer ring 501, an inner ring 502, and a sealing element 503. The outer ring 501 is sleeved on the outside of the inner ring 502. The sealing element 503 is connected to the same axial end of the outer ring 501 and the inner ring 502, and cooperates with the outer ring 501 and the inner ring 502 to form a sealing part. The sealing part is located on the side of the sealing ring 5 facing the generator intake pipe connecting flange, and is used to fit against the axial end face of the connecting flange.

[0070] In this embodiment, the seal 503 can be an annular elastic element. The seal 503 is disposed at one end of the outer ring 501 and the inner ring 502 facing the generator intake pipe connecting flange, and covers the end face area of ​​the outer ring 501 and the inner ring 502 at that end. That is, the seal 503 spans the outer ring 501 and the inner ring 502 in the radial direction so that it is simultaneously acted upon by the outer ring 501 and the inner ring 502, and is used to fit against the axial end face of the connecting flange.

[0071] Specifically, the outer ring 501 can be made of high-pressure expandable fluororubber material. When the pressure difference between the inside and outside of the connection exceeds a set threshold, the outer ring 501 expands radially. The inner ring 502 can be made of high-temperature shrinkage memory alloy material. When the temperature of the connection area exceeds a set threshold, the inner ring 502 shrinks radially.

[0072] Since the seal 503 connects both the outer ring 501 and the inner ring 502, when the outer ring 501 expands radially and the inner ring 502 contracts radially, the two can jointly change the stress state of the seal 503, causing the seal 503 to press tightly against the axial end face of the connecting flange. Therefore, during the operation of the generator's salt spray protection device, the sealing ring 5 can adjust its sealing according to changes in pressure difference and temperature in the connection area, thereby reducing the possibility of salt spray seeping in through the connection gap and improving the sealing reliability of the connection.

[0073] like Figure 1 As shown, the salt discharge assembly 6 is located on the outside of the cylinder 2 and is connected to the first collection tank 8 and the second collection tank 10. It is used to collect and discharge the salt solution generated during the separation and adsorption process. The salt discharge assembly 6 includes a collection box 601, a first collection pipe 603, a second collection pipe 604, and a salt discharge port 602.

[0074] Specifically, a collection box 601 is located on the outside of the cylinder 2 and is used to collect the brine solution. In some embodiments, the collection box 601 may be configured as a closed or semi-closed cavity structure to temporarily store the introduced brine solution and provide space for subsequent unified discharge.

[0075] See Figure 2The first collection pipe 603 communicates with the first collection tank 8 and the collection box 601, and is used to discharge the brine solution separated by the interception component 7 and collected by the first collection tank 8. Preferably, the first collection pipe 603 can extend from the first collection tank 8 to the collection box 601 so that the brine solution enters the collection box 601 along the liquid guiding path. In some embodiments, the first collection pipe 603 can utilize the height difference to allow the brine solution to flow by gravity to the collection box 601, thereby simplifying the drainage structure.

[0076] See Figure 2 The second collecting tank 10 is connected to the capillary tube 12, which in turn is connected to the second collecting pipe 604 and the collecting tank 601. This connection is used to discharge the salt solution that has been adsorbed by the adsorption component 11 and discharged through the capillary tube 12. Preferably, the second collecting pipe 604 extends from the outlet end of the capillary tube 12 to the collecting tank 601, allowing the discharged salt solution to be collected in the collecting tank 601. In this way, the salt solution formed during the treatment by the adsorption component 11 can leave the adsorption area and be centrally stored in the collecting tank 601.

[0077] like Figure 2 As shown, the salt drain port 602 is located on the outer surface of the collection tank 601 and communicates with the interior of the collection tank 601, for draining the salt solution in the collection tank 601. Furthermore, the salt drain port 602 can be located at the bottom of the collection tank 601 or in other convenient locations for drainage, to facilitate the discharge of the salt solution from the collection tank 601.

[0078] The working principle of this embodiment is as follows: After the generator anti-salt spray device is installed at the front end of the air intake pipe of the marine generator, the outside air containing salt spray enters the cylinder 2 through the air intake 1 under the action of the negative pressure of the air intake, and first passes through the filter screen 4 to remove larger particulate solid impurities. Then, the airflow enters the interception component 7, where large particulate salt spray droplets in the airflow are blocked by the interception disk 701 and flow into the first collection tank 8, while the gas continues to flow downward through the vent hole 702.

[0079] After initial separation, the airflow forms a swirling flow under the guidance of the guide ribs 201, and the swirling state is further enhanced by the swirling component 9, causing small salt spray droplets in the airflow to be thrown outwards and enter the second collection tank 10. The airflow then continues into the adsorption component 11, where residual salt spray is further adsorbed and purified by the porous adsorption element 1102. The adsorbed liquid enters the capillary tube 12 through the connecting hole 1201 and is discharged under capillary or siphon action to mitigate the saturation failure of the porous adsorption element 1102. Finally, the purified air enters the generator intake pipe through the outlet 3.

[0080] Meanwhile, the sealing ring 5 is located at the connection between the air outlet 3 and the generator intake pipe. It can adjust the seal according to changes in temperature and pressure difference to improve the sealing stability of the connection and reduce the possibility of salt spray seeping in through the connection gap.

[0081] During generator operation, the brine separated by the interception component 7 and collected by the first collection tank 8 can enter the collection tank 601 through the first collection pipe 603; the liquid adsorbed by the adsorption component 11 and discharged by the capillary 12 can enter the collection tank 601 through the second collection pipe 604. After the liquids from different paths are collected in the collection tank 601, they can be discharged through the salt discharge port 602 for centralized treatment.

[0082] The above settings allow for the unified export of salt solution generated throughout the generator, reducing the adverse effects of salt solution accumulation, retention, or backflow on the operation of the generator's anti-salt spray device.

[0083] In some embodiments, the present invention also provides a generator, including a generator body and the aforementioned generator salt spray protection device. The outlet 3 of the generator salt spray protection device is connected to the air intake channel of the generator body. Thus, before entering the generator body, outside air undergoes interception, separation, swirling separation, and adsorption purification treatment by the generator salt spray protection device, and then enters the air intake channel of the generator body through the outlet 3, thereby reducing the possibility of salt spray entering the generator body and improving the operational reliability of the generator body in high salt spray environments.

[0084] This invention achieves graded removal and centralized discharge of salt mist in the generator intake air by sequentially arranging an interception component 7, a swirling component 9, and an adsorption component 11 along the airflow direction inside the cylinder 2. This allows the salt mist-containing airflow to undergo interception separation, swirling separation, and adsorption purification treatment in sequence. The salt solution formed by separation and adsorption is then discharged through the salt discharge component 6. This improves the cleanliness of the generator intake air and the continuous working capability of the generator's anti-salt mist device. At the same time, by setting an anti-backflow structure at the second collection tank 10 and cooperating with the liquid guiding effect of the capillary 12, the possibility of salt solution backflow and salt crystal deposition can be reduced.
