Description

Technical Field

[0001] The present invention relates to the technical field related to gas turbines, and in particular to a gas turbine air intake filter device with a silencer structure and a use method thereof. Background Art

[0002] The existing gas turbine is a device that supplies energy to other mechanisms by burning combustible gas. The combustible gas is generally natural gas, which needs to be mixed with air before combustion to ensure its full combustion. Therefore, the gas turbine is usually equipped with a natural gas inlet and an air inlet.

[0003] Under harsh working conditions of the gas turbine (for example, poor air quality and a lot of dust and foreign matter in the air), the air entering the gas turbine is easily impure, which in turn affects the combustion effect and the operation of the internal components of the gas turbine. For this reason, a corresponding filtering structure is usually required in the air intake system of the gas turbine.

[0004] However, in the actual implementation of the existing filtering means, the filter elements are prone to clogging. When clogging occurs, it will affect the intake process and even cause intake interruption. In turn, insufficient air will be involved in combustion, causing energy shortage or interruption, which may cause great losses and often make the operation of the intake system fail to achieve the ideal stability.

A lug is arranged on the side of the arc-shaped sheet 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 protruding block.

[0010] As a further solution of the present invention: the circumferential cleaning mechanism comprises a transmission shaft rotatably mounted in the conveying pipe, a transmission cylinder slidably sleeved with the transmission shaft through a conductive structure, and a cleaning member fixed to the transmission cylinder; Wherein, the transmission cylinder is rotatably connected to the filter disc, the cleaning member is in contact with the filter disc, and the transmission shaft is connected to the elastic storage mechanism via a sliding fitting assembly.

[0011] As a further solution of the present invention: the conductive 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, and the strip-shaped grooves are adapted to the strip-shaped protrusions.

[0012] As a further solution 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 comprises an assembly cylinder provided on the sleeve plate and a driving column slidably sleeved with the assembly cylinder, the driving column is connected to a ring body slidably provided in the assembly cylinder, and a second cylindrical spring and a third cylindrical spring are sleeved on the outer circumference of the driving column; Among them, the head ends of the second cylindrical spring and the third cylindrical spring are connected to the ring body, and the tail ends are connected to the inner wall of the assembly cylinder, one end of the driving column is connected to the sliding matching component, and the other end is provided with two second columns, and a first column is respectively provided on both sides of the sleeve plate, and the first column and the second column cooperate with the limit plate provided on the conveying pipeline.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention has a novel design, and as the working time increases, more foreign matter will accumulate on the side of the filter disc facing the silencer structure. As the amount of accumulation increases, the filter disc may be blocked, thereby leading to the problem of low ventilation efficiency. When such a situation occurs, under the action of air blowing, the filter disc moves in the direction away from the silencer structure, and accordingly, the elastic support mechanism prompts the elastic storage mechanism to store and release elastic potential energy. When the elastic storage mechanism releases the elastic potential energy, it will drive the circumferential cleaning mechanism to perform a cleaning action on the filter disc, so that the foreign matter accumulated on the filter disc is separated from the filter disc, making the filter disc conductive. Therefore, the function of automatically unblocking the filter disc when it is blocked is realized, avoiding the loss caused by sudden interruption of the intake process during operation, making the intake system of the gas turbine more stable and suitable for popularization and use.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0028] See also Figure 1-Figure 8 In an embodiment of the present invention, a gas turbine air intake filter device with a silencing structure includes a delivery pipeline 1, and also includes: A silencer structure is provided inside the delivery pipeline 1. After passing through the silencer structure, air can enter the delivery pipeline 1, and then enter the gas turbine through the delivery pipeline 1 for combustion reaction. A filter plate 6 is movably disposed in the conveying pipe 1 and connected to two sets of elastic support mechanisms installed on the outer wall of the conveying pipe 1, and the elastic support mechanisms are connected to elastic storage mechanisms arranged on the outer wall of the conveying pipe 1; A circumferential cleaning mechanism is arranged in the conveying pipeline 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 in a blocked state, the elastic support mechanism can prompt the elastic storage mechanism to successively store and release elastic potential energy, and when the elastic storage mechanism releases the elastic potential energy, it can drive the circumferential cleaning mechanism to perform a cleaning action on the filter disc 6 to restore the filter disc 6 to a conductive state.

[0029] Specifically, in actual operation, the air first enters the silencer structure, and then the silencer structure eliminates the noise generated when the air enters, to avoid excessive noise and cause excessive sound pollution; Subsequently, the silenced air will pass through the filter disc 6 and enter the gas turbine for combustion reaction. The 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, resulting in poor combustion effect and interference with the operation of the internal components of the gas turbine, thereby affecting the life of the gas turbine. Among them, as the working time increases, more foreign matter will accumulate on the side of the filter disc 6 facing the silencer structure. As the amount of accumulation increases, the filter disc 6 may be blocked, which will lead to the problem of low ventilation efficiency. When such a situation occurs, the filter disc 6 moves in the direction away from the silencer structure under the action of air blowing. Accordingly, the elastic support mechanism prompts the elastic storage mechanism to store and release elastic potential energy. When the elastic storage mechanism releases the elastic potential energy, it will drive the circumferential cleaning mechanism to perform a cleaning action on the filter disc 6, so that the foreign matter accumulated on the filter disc 6 is separated from the filter disc 6, so that the filter disc 6 is conductive. Therefore, the function of automatically unblocking the filter disc 6 when it is blocked is realized, avoiding the loss caused by the sudden interruption of the intake process during work, making the intake system of the gas turbine more stable and suitable for popularization and use; When it is necessary to explain, a corresponding opening should be provided on the conveying pipeline 1. Whenever the work is completed, the staff should open the opening to check whether there are any foreign objects removed from the conveying pipeline 1 and guide the foreign objects out in time.

[0030] Please refer again Figure 4 The silencing structure includes an air cutting assembly arranged in the delivery pipeline 1 and a multi-layer stacking assembly arranged along the circumference of the delivery pipeline 1, and the cutting assembly includes a gas separator 2 arranged inside the delivery pipeline 1; The gas separator 2 is distributed along the axial direction of the delivery pipeline 1 , and a plurality of arc-shaped support arms 201 are formed on the gas separator 2 , and the plurality of arc-shaped support arms 201 are distributed equidistantly along the circumference.

[0031] The multi-layer superimposed assembly includes a first sound insulation layer 3, a second sound insulation layer 4 and a third sound insulation layer 5 which are sequentially fitted from the inside to the outside of the conveying pipeline 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.

[0032] It should be noted that the gas separator 2 is the same as the first sound insulation layer 3, the second sound insulation layer 4 and the third sound insulation layer 5, and is also supported by sound insulation materials. When the gas passes through the gas separator 2, it will be separated into multiple airflows by multiple arc-shaped arms 201, so that the sound waves propagate divergently, and the gas separator 2 will reduce the noise for the first time. Since the gas separator 2 is distributed along the axial direction of the conveying pipeline 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 to reduce noise, thereby greatly reducing noise pollution.

[0033] Please refer again Figure 5 and Figure 6 The filter disc 6 is sealingly and slidably fitted with the inner wall of the delivery pipe 1, and two guide grooves 101 are axially provided on the delivery pipe 1, and an arc-shaped piece 12 is respectively sealingly and slidably fitted in the two guide grooves 101, and the two arc-shaped pieces 12 are fixed to the filter disc 6; The elastic support mechanism includes a guide rod 16 arranged on the outer wall of the conveying pipe 1 through a protruding block 15 and a first cylindrical spring 17 sleeved on the outer periphery of the guide rod 16. A lug 13 is arranged on the side of the arc-shaped sheet 12 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 protruding block 15.

[0034] Furthermore, when the filter disc 6 is not blocked, air can pass through the filter disc 6 normally, so the first cylindrical spring 17 can support the filter disc 6, so that the filter disc 6 remains stationary in the conveying pipeline 1; As the working time increases, when the filter disc 6 is blocked, it is difficult for air to pass through the filter disc 6, so the filter disc 6 will be blown, causing the filter disc 6 to slide away from the gas separator 2 in the conveying pipe 1, and accordingly, the lug 13 slides on the guide rod 16 close to the protrusion 15, and the first cylindrical spring 17 is compressed. The lug 13 prompts the elastic storage mechanism to store elastic potential energy. When the filter disc 6 moves a certain distance (that is, it indicates that the filter disc 6 is seriously blocked at this time and will affect the air intake), the elastic storage mechanism releases the stored elastic potential energy to prompt the circular cleaning mechanism to clean the filter disc 6.

[0035] Please refer again Figure 6 and Figure 7The circumferential cleaning mechanism includes a transmission shaft 9 rotatably mounted in the conveying pipe 1, a transmission cylinder 10 slidably fitted with the transmission shaft 9 through a conductive structure, and a cleaning member 7 fixed to the transmission cylinder 10. The transmission cylinder 10 is rotatably connected to the filter disc 6, the cleaning member 7 abuts against the filter disc 6, and the transmission shaft 9 is connected to the elastic storage mechanism through a sliding fitting assembly.

[0036] The conductive 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 , and the strip-shaped grooves 1001 are adapted to the strip-shaped protrusions 901 .

[0037] 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, and the cleaning member 7 maintains abutment with the filter disc 6. Subsequently, the elastic storage mechanism releases the elastic potential energy, which prompts the sliding fitting assembly to drive the transmission shaft 9 to rotate. The transmission shaft 9 drives the transmission cylinder 10 and the cleaning member 7 to rotate through the strip protrusions 901 and the strip grooves 1001. The cleaning member 7 cleans the foreign matter on the filter disc 6, so that the filter disc 6 resumes conduction, so that the air intake continues to be unobstructed.

[0038] Please refer 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 provided on the sleeve plate 20 and a driving column 22 slidably fitted with the assembly cylinder 21. The driving column 22 is connected to a ring body 23 slidably provided in the assembly cylinder 21, and a second cylindrical spring 24 and a third cylindrical spring 25 are also sleeved on the outer periphery of the driving column 22; Among them, the head ends of the second cylindrical spring 24 and the third cylindrical spring 25 are connected to the ring body 23, and the tail ends are connected to the inner wall of the assembly cylinder 21. One end of the driving column 22 is connected to the sliding matching component, and the other end is provided with two second columns 2201. A first column 2001 is respectively provided on both sides of the sleeve plate 20, and the first column 2001 and the second column 2201 cooperate with the limit plate 18 provided on the conveying pipeline 1.

[0039] The limiting plate 18 is fixed to the lug 13 through the connecting arm 14. The limiting plate 18 is provided with an inclined groove 1805 adapted to the first column 2001, and is also provided with 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 slide groove 1801, a second slide groove 1802, a third slide groove 1803 and a fourth slide groove 1804 that are connected.

[0040] Taking the state of the attached figure as an example, when the filter disc 6 is in a normal state and air can pass through smoothly, the second column 2201 is located at the connection between the first slide groove 1801 and the fourth slide groove 1804. When the filter disc 6 is gradually blocked, the filter disc 6 drives the limit plate 18 to move through the lug 13 and the connecting arm 14. At this time, the first column 2001 slides with the limit plate 18 through the inclined groove 1805, so that the sleeve plate 20 moves on the guide plate 19 close to the conveying pipe 1. At this time, the second column 2201 is located in the first slide groove 1801, so that The second cylindrical spring 24 is compressed, and when the second column 2201 corresponds to the connection between the first slide groove 1801 and the second slide groove 1802, that is, at this time, the blockage of the filter disc 6 is relatively serious, which may affect the normal delivery of air. Then, the second cylindrical spring 24 rebounds, and the driving column 22 slides on the assembly cylinder 21 close to the delivery pipe 1, so that the second column 2201 corresponds to the connection between the second slide groove 1802 and the third slide groove 1803, and the sliding matching mechanism is triggered, driving the transmission shaft 9 to rotate, so that the cleaning member 7 cleans the filter disc 6; After the filter disc 6 is cleaned, it can restore its initial conductance, and then the first column spring 17 can rebound, so that the filter disc 6 and the limit plate 18 are reset. During the reset of the limit plate 18, the first column 2001 will slide with the limit plate 18 again through the inclined groove 1805, so that the sleeve plate 20 slides away from the conveying pipeline 1 on the guide plate 19 and resets. The third column spring 25 is compressed, and when the second column 2201 corresponds to the connection between the third slide groove 1803 and the fourth slide groove 1804, the third column spring 25 rebounds, prompting the driving column 22 to reset.

[0041] The sliding fit assembly includes a driven shaft 11 rotatably mounted in the conveying pipe 1, the driven shaft 11 is connected to the transmission shaft 9 via a bevel gear set 8, and the end of the driving column 22 away from the second column 2201 is connected to a driving pipe 27 slidably mounted on the driven shaft 11 via a transmission arm 26, a boss is provided on the inner wall of the driving pipe 27, the boss 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.

[0042] When the second cylindrical spring 24 and the third cylindrical spring 25 rebound, the driving column 22 will drive the driving pipe 27 to slide on the driven shaft 11 through the transmission arm 26, so that the boss will slide with the driven shaft 11 through the spiral groove 1101, so that the driven shaft 11 rotates, and the driven shaft 11 can drive the transmission shaft 9 to rotate through the bevel gear set 8.

[0043] Specifically, 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 is meshed with the first bevel gear.

[0044] As another embodiment of the present invention, a method for using the gas turbine air intake filter device with a silencer structure is also proposed, comprising the following steps: Step 1: placing the delivery pipeline 1 in the air intake system of the gas turbine; Step 2: air enters the delivery pipe 1 and is cut into multiple air streams by the silencer structure for silencer and noise reduction processing; Step 3, the silenced air is filtered through the filter disc 6 and enters the gas turbine for combustion reaction; Step 4: When the filter disc 6 is blocked, the elastic support mechanism prompts the elastic storage mechanism to store and release elastic potential energy in turn. When the elastic storage mechanism releases the elastic potential energy, it drives the circumferential cleaning mechanism to clean the filter disc 6, so that the filter disc 6 returns to a conductive state.

[0045] It will be apparent to those skilled in the art that the 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 the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0046] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
