Description

Technical Field

[0001] This invention relates to the technical field of gas turbines, specifically to a gas turbine inlet air filtration device with a noise reduction structure and its usage method. Background Technology

[0002] An existing gas turbine is a device that supplies energy to other components by burning combustible gas. The combustible gas is generally natural gas. Natural gas needs to be mixed with air before combustion to ensure complete combustion. Therefore, gas turbines are usually equipped with both natural gas inlets and air inlets.

[0003] In harsh operating environments (such as poor air quality or high levels of dust and foreign matter), the air entering the gas turbine may not be pure enough, which can affect combustion efficiency and the operation of internal components. Therefore, the gas turbine's intake system usually needs to be equipped with appropriate filtration structures.

[0004] However, in practice, the filter components of existing filtration methods are prone to clogging. When clogging occurs, it will affect the air intake process and even cause the air intake to be interrupted. Consequently, there will be insufficient air to participate in combustion, leading to insufficient or interrupted energy supply, which may cause significant losses and often prevent the air intake system from operating as stably as desired. Summary of the Invention

[0005] The purpose of this invention is to provide a gas turbine intake air filtration device with a noise reduction structure and its usage method, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A gas turbine inlet air filtration device with a noise reduction structure includes a delivery pipe and further includes:

[0008] A noise-reducing structure is provided inside the conveying pipe. After passing through the noise-reducing structure, air can enter the conveying pipe and then enter the gas turbine for combustion reaction.

The elastic support mechanism is connected to an elastic storage mechanism disposed on the outer wall of the conveying pipe.

[0010] A circumferential cleaning mechanism is located inside the conveying pipe and connected to the filter disc. The circumferential cleaning mechanism is connected to the elastic storage mechanism. When the filter disc is blocked, the elastic support mechanism can cause the elastic storage mechanism to store and release elastic potential energy sequentially. When the elastic storage mechanism releases elastic potential energy, it can drive the circumferential cleaning mechanism to perform a cleaning action on the filter disc so that the filter disc can be restored to a conductive state.

[0011] As a further aspect of the present invention: the noise reduction structure includes an air cutting component disposed within the conveying pipe and a multi-layer stacked component disposed along the circumference of the conveying pipe, wherein the cutting component includes a gas separator disposed inside the conveying pipe;

[0015] The elastic support mechanism includes a guide rod disposed on the outer wall of the conveying pipe via a protrusion and a first cylindrical spring sleeved on the outer periphery of the guide rod. The arc-shaped plate has a lug on the side away from the filter disc. The lug is slidably connected to the guide rod, and the two ends of the first cylindrical spring are respectively connected to the lug and the protrusion.

[0016] As a further embodiment of the present invention: the circumferential cleaning mechanism includes a drive shaft rotatably installed in the conveying pipe, a drive cylinder slidably fitted with the drive shaft through a transmission structure, and a cleaning component fixed to the drive cylinder;

[0017] The transmission cylinder is rotatably connected to the filter disc, the cleaning component abuts against the filter disc, and the transmission shaft is connected to the elastic storage mechanism through a sliding fit assembly.

[0018] As a further embodiment of the present invention: the transmission structure includes two strip-shaped protrusions formed on the outer wall of the transmission shaft and distributed along the axial direction of the transmission shaft, and two strip-shaped grooves provided on the inner wall of the transmission cylinder, wherein the strip-shaped grooves are adapted to the strip-shaped protrusions.

[0019] As a further embodiment of the present invention: a guide plate is fixedly provided on the outer wall of the conveying pipe, a sleeve plate is slidably provided on the guide plate, the elastic storage mechanism includes an assembly cylinder disposed on the sleeve plate and a drive column slidably fitted with the assembly cylinder, the drive column is connected to an annular body slidably disposed in the assembly cylinder, and a second columnar spring and a third columnar spring are also sleeved on the outer periphery of the drive column.

[0020] The first ends of the second and third cylindrical springs are connected to the ring body, and the tail ends are connected to the inner wall of the assembly cylinder. One end of the drive column is connected to the sliding fit assembly, and the other end is provided with two second columns. A first column is provided on each side of the sleeve plate. The first column and the second column cooperate with the limiting plate provided on the conveying pipe.

[0021] As a further embodiment of the present invention: the limiting plate is fixed to the lug by a connecting arm, the limiting plate is provided with an inclined groove adapted to the first column, and also with a rectangular groove adapted to the second column, the first column and the second column respectively extend into the inclined groove and the rectangular groove, and are slidably connected with the limiting plate, the rectangular groove includes a first sliding groove, a second sliding groove, a third sliding groove and a fourth sliding groove connected together.

[0022] As a further embodiment of the present invention: the sliding fit assembly includes a driven shaft rotatably installed in the conveying pipe, the driven shaft being connected to the transmission shaft via a bevel gear set, and the end of the drive column away from the second column being connected to a drive tube slidably sleeved on the driven shaft via a transmission arm, the inner wall of the drive tube being provided with a protruding post, the protruding post extending into a spiral groove provided on the outer wall of the driven shaft and being slidably connected to the driven shaft.

[0023] A method of using the gas turbine inlet air filter device with a noise reduction structure includes the following steps:

[0024] Step 1: Install the delivery pipeline into the gas turbine's intake system;

[0025] Step two: Air enters the delivery pipe and is cut into multiple airflows by the sound-absorbing structure for noise reduction.

[0026] Step 3: The silenced air is filtered through a filter disc and then enters the gas turbine for combustion.

[0027] Step four: When the filter disc is clogged, the elastic support mechanism causes the elastic storage mechanism to store and release elastic potential energy in sequence. When the elastic storage mechanism releases elastic potential energy, it drives the circumferential cleaning mechanism to clean the filter disc and restore the filter disc to its conductive state.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention has a novel design. As the working time increases, more foreign matter will accumulate on the side of the filter disc facing the silencing structure. As the accumulation increases, the filter disc may become clogged, leading to low ventilation efficiency. When this happens, the filter disc moves away from the silencing structure under the action of air blowing. Correspondingly, the elastic support mechanism causes the elastic storage mechanism to store and release elastic potential energy. When the elastic storage mechanism releases elastic potential energy, it will drive the circumferential cleaning mechanism to perform a cleaning action on the filter disc, causing the foreign matter accumulated on the filter disc to detach from the filter disc and making the filter disc unobstructed. Therefore, the filter disc can be automatically unblocked when it becomes clogged, avoiding the loss caused by sudden interruption of the air intake process during operation, making the gas turbine's air intake system more stable and suitable for widespread use.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0040] Please see Figures 1-8 In this embodiment of the invention, a gas turbine intake air filtration device with a noise reduction structure includes a delivery pipe 1, and further includes:

[0041] A noise reduction structure is provided inside the conveying pipe 1. After passing through the noise reduction structure, air can enter the conveying pipe 1 and then enter the gas turbine for combustion reaction.

[0042] The filter disc 6 is movably disposed inside the conveying pipe 1 and connected to two sets of elastic support mechanisms installed on the outer wall of the conveying pipe 1. The elastic support mechanism is connected to an elastic storage mechanism disposed on the outer wall of the conveying pipe 1.

[0043] A circumferential cleaning mechanism is located inside the conveying pipe 1 and connected to the filter disc 6. The circumferential cleaning mechanism is connected to the elastic storage mechanism. When the filter disc 6 is blocked, the elastic support mechanism can cause the elastic storage mechanism to store and release elastic potential energy sequentially. When the elastic storage mechanism releases elastic potential energy, it can drive the circumferential cleaning mechanism to perform a cleaning action on the filter disc 6 so that the filter disc 6 can be restored to the conductive state.

[0044] Specifically, in actual operation, air first enters the silencing structure, and then the silencing structure eliminates the noise generated when the air enters, thus avoiding excessive noise and causing serious sound pollution.

[0045] Subsequently, the silenced air will enter the gas turbine through filter disc 6 for combustion. Filter disc 6 can filter out impurities in the air to ensure that the air entering the gas turbine is pure and prevent impurities from entering the gas turbine to participate in combustion, which would lead to poor combustion effect and interference with the operation of internal components of the gas turbine, thereby affecting the life of the gas turbine.

[0046] As working time increases, more foreign matter accumulates on the side of the filter disc 6 facing the silencing structure. As the accumulation increases, the filter disc 6 may become clogged, leading to low ventilation efficiency. When this happens, the air blowing causes the filter disc 6 to move away from the silencing structure. Correspondingly, the elastic support mechanism causes the elastic storage mechanism to store and release elastic potential energy. When the elastic storage mechanism releases elastic potential energy, it drives the circumferential cleaning mechanism to perform a cleaning action on the filter disc 6, causing the foreign matter accumulated on the filter disc 6 to detach from the filter disc 6 and making the filter disc 6 open. Therefore, the filter disc 6 can be automatically unblocked when it becomes clogged, avoiding the loss caused by the sudden interruption of the air intake process during operation. This makes the gas turbine's air intake system more stable and suitable for widespread use.

[0047] It should be noted that a corresponding opening should be provided on the conveying pipe 1. After each work is completed, the staff should open the opening to check whether there are any foreign objects removed from the conveying pipe 1, and promptly remove the foreign objects.

[0048] Please refer to it again. Figure 4The noise reduction structure includes an air cutting assembly disposed in the conveying pipe 1 and a multi-layer stacked assembly disposed along the circumference of the conveying pipe 1. The cutting assembly includes a gas separator 2 disposed inside the conveying pipe 1.

[0049] The gas separator 2 is distributed along the axial direction of the conveying pipe 1, and a plurality of arc-shaped support arms 201 are formed on the gas separator 2, which are distributed at equal intervals along the circumference.

[0050] The multi-layer stacked assembly includes a first sound insulation layer 3, a second sound insulation layer 4, and a third sound insulation layer 5, which are sequentially nested from the inside to the outside of the conveying pipe 1. The first sound insulation layer 3, the second sound insulation layer 4, and the third sound insulation layer 5 form a sound-absorbing layer group and correspond to the position of the gas separator 2.

[0051] It should be noted that the gas separator 2, like the first sound insulation layer 3, the second sound insulation layer 4, and the third sound insulation layer 5, is also supported by sound insulation material. When the gas passes through the gas separator 2, it will be separated into multiple airflows by multiple arc-shaped support arms 201. As a result, the sound waves propagate in a divergent manner, and the gas separator 2 reduces noise for the first time. Since the gas separator 2 is distributed along the axial direction of the conveying pipe 1 and has a certain length, when the multiple airflows move along the length of the gas separator 2, they will pass through the first sound insulation layer 3, the second sound insulation layer 4, and the third sound insulation layer 5 for noise reduction, thereby significantly reducing noise pollution.

[0052] Please refer to it again. Figure 5 and Figure 6 The filter disc 6 is sealed and slidably fitted to the inner wall of the conveying pipe 1, and two guide grooves 101 are provided along the axial direction on the conveying pipe 1. An arc-shaped piece 12 is sealed and slidably fitted in each of the two guide grooves 101, and the two arc-shaped pieces 12 are fixed to the filter disc 6.

[0053] The elastic support mechanism includes a guide rod 16 disposed on the outer wall of the conveying pipe 1 via a protrusion 15 and a first cylindrical spring 17 sleeved on the outer periphery of the guide rod 16. The arc-shaped plate 12 is provided with a lug 13 on the side away from the filter disc 6. The lug 13 is slidably connected to the guide rod 16, and the two ends of the first cylindrical spring 17 are respectively connected to the lug 13 and the protrusion 15.

[0054] Furthermore, when the filter disc 6 is not clogged, air can pass through the filter disc 6 normally. Therefore, the first cylindrical spring 17 can support the filter disc 6, so that the filter disc 6 remains stationary in the conveying pipe 1.

[0055] As working time increases, when filter disc 6 becomes clogged, air has difficulty passing through it. As a result, filter disc 6 is blown away, causing it to slide away from gas separator 2 within the delivery pipe 1. Correspondingly, lug 13 slides close to protrusion 15 on guide rod 16, compressing the first cylindrical spring 17. Lug 13 then causes the elastic storage mechanism to store elastic potential energy. When filter disc 6 moves a certain distance (indicating that the blockage of filter disc 6 is severe and will affect air intake), the elastic storage mechanism releases the stored elastic potential energy to prompt the circumferential cleaning mechanism to clean filter disc 6.

[0056] Please refer to it again. Figure 6 and Figure 7 The circumferential cleaning mechanism includes a drive shaft 9 rotatably mounted inside the conveying pipe 1, a drive cylinder 10 slidably fitted with the drive shaft 9 via a transmission structure, and a cleaning component 7 fixed to the drive cylinder 10. The drive cylinder 10 is rotatably connected to the filter disc 6, the cleaning component 7 abuts against the filter disc 6, and the drive shaft 9 is connected to the elastic storage mechanism via a sliding fit assembly.

[0057] The transmission structure includes two strip-shaped protrusions 901 formed on the outer wall of the transmission shaft 9 and distributed along the axial direction of the transmission shaft 9, and two strip-shaped grooves 1001 provided on the inner wall of the transmission cylinder 10, wherein the strip-shaped grooves 1001 are adapted to the strip-shaped protrusions 901.

[0058] When the filter disc 6 moves due to blockage, the filter disc 6 drives the transmission cylinder 10 to slide on the transmission shaft 9. The cleaning component 7 remains in contact with the filter disc 6. Subsequently, the elastic storage mechanism releases elastic potential energy, which causes the sliding engagement component to drive the transmission shaft 9 to rotate. The transmission shaft 9 drives the transmission cylinder 10 and the cleaning component 7 to rotate through the strip protrusion 901 and the strip groove 1001. The cleaning component 7 then cleans the foreign matter on the filter disc 6, so that the filter disc 6 is restored to conduction, allowing the air intake to continue to proceed smoothly.

[0059] Please refer to it again. Figure 5 , Figure 7 as well as Figure 8 The outer wall of the conveying pipe 1 is fixedly provided with a guide plate 19, and a sleeve plate 20 is slidably provided on the guide plate 19. The elastic storage mechanism includes an assembly cylinder 21 disposed on the sleeve plate 20 and a drive column 22 slidably fitted with the assembly cylinder 21. The drive column 22 is connected to an annular body 23 slidably disposed in the assembly cylinder 21, and a second columnar spring 24 and a third columnar spring 25 are also sleeved on the outer periphery of the drive column 22.

[0060] The first end of the second cylindrical spring 24 and the first end of the third cylindrical spring 25 are connected to the ring body 23, and the second end is connected to the inner wall of the assembly cylinder 21. One end of the drive column 22 is connected to the sliding engagement assembly, and the other end is provided with two second columns 2201. A first column 2001 is provided on each side of the sleeve plate 20. The first column 2001 and the second column 2201 cooperate with the limiting plate 18 provided on the conveying pipe 1.

[0061] The limiting plate 18 is fixed to the lug 13 via the connecting arm 14. The limiting plate 18 is provided with an inclined groove 1805 adapted to the first column 2001 and a rectangular groove adapted to the second column 2201. The first column 2001 and the second column 2201 extend into the inclined groove 1805 and the rectangular groove respectively, and are slidably connected to the limiting plate 18. The rectangular groove includes a first sliding groove 1801, a second sliding groove 1802, a third sliding groove 1803 and a fourth sliding groove 1804 connected together.

[0062] Taking the attached diagram as an example, when the filter disc 6 is in a normal state and air can pass through freely, the second column 2201 is located at the connection between the first slide groove 1801 and the fourth slide groove 1804. As the filter disc 6 gradually becomes clogged, it moves the limiting plate 18 via the lug 13 and the connecting arm 14. At this time, the first column 2001 slides against the limiting plate 18 via the inclined groove 1805, causing the sleeve 20 to move closer to the conveying pipe 1 on the guide plate 19. Meanwhile, the second column 2201 is located within the first slide groove 1801, thus… When the second columnar spring 24 is compressed, and the second column 2201 aligns with the connection between the first slide groove 1801 and the second slide groove 1802, the filter disc 6 is severely clogged, which may affect the normal air delivery. Then, the second columnar spring 24 rebounds, and the drive column 22 slides on the assembly cylinder 21 close to the delivery pipe 1, causing the second column 2201 to align with the connection between the second slide groove 1802 and the third slide groove 1803. The sliding engagement mechanism is triggered, driving the transmission shaft 9 to rotate, so that the cleaning component 7 cleans the filter disc 6.

[0063] After the filter disc 6 is cleaned, it can restore its initial conductivity. Then, the first columnar spring 17 can rebound, causing the filter disc 6 and the limiting plate 18 to reset. During the reset process of the limiting plate 18, the first column 2001 will slide and engage with the limiting plate 18 again through the inclined groove 1805, so that the sleeve 20 slides and resets away from the conveying pipe 1 on the guide plate 19. The third columnar spring 25 is compressed. When the second column 2201 corresponds to the connection between the third slide groove 1803 and the fourth slide groove 1804, the third columnar spring 25 rebounds, causing the drive column 22 to reset.

[0064] The sliding fit assembly includes a driven shaft 11 rotatably installed in the conveying pipe 1. The driven shaft 11 is connected to the transmission shaft 9 through a bevel gear set 8. The end of the drive column 22 away from the second column 2201 is connected to a drive tube 27 slidably sleeved on the driven shaft 11 through a transmission arm 26. A protruding post is provided on the inner wall of the drive tube 27. The protruding post extends into a spiral groove 1101 provided on the outer wall of the driven shaft 11 and is slidably connected to the driven shaft 11.

[0065] When the second columnar spring 24 and the third columnar spring 25 rebound, the drive column 22 will drive the drive tube 27 to slide on the driven shaft 11 through the transmission arm 26. Then, the protrusion will slide with the driven shaft 11 through the spiral groove 1101, causing the driven shaft 11 to rotate. The driven shaft 11 can then drive the transmission shaft 9 to rotate through the bevel gear set 8.

[0066] In detail, the bevel gear set 8 includes a first bevel gear mounted on the driven shaft 11 and a second bevel gear disposed on the transmission shaft 9, and the second bevel gear meshes with the first bevel gear.

[0067] As another embodiment of the present invention, a method for using the gas turbine intake air filter device with a noise reduction structure is also provided, comprising the following steps:

[0068] Step 1: Install the delivery pipeline 1 into the gas turbine's intake system;

[0069] Step 2: Air enters the delivery pipe 1 and is cut into multiple airflows by the sound-absorbing structure for noise reduction.

[0070] Step 3: The silenced air is filtered through filter plate 6 and enters the gas turbine for combustion reaction;

[0071] Step four: When filter disc 6 is clogged, the elastic support mechanism causes the elastic storage mechanism to store and release elastic potential energy in sequence. When the elastic storage mechanism releases elastic potential energy, it drives the circumferential cleaning mechanism to clean the filter disc 6, so that the filter disc 6 returns to the conductive state.

[0072] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0073] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution.
