Description

Technical Field

[0001] This utility model relates to the field of gas turbines, specifically to a gas turbine with a cleaning function. Background Technology

[0002] After prolonged operation, gas turbine blades require cleaning to remove adhering impurities. In related technologies, an annular pipe is fitted around the outer end of the intake chamber shaft outside the cylinder. This annular pipe has nozzles that extend axially towards the blades along the cylinder axis, spraying liquid to clean the blades. However, because the nozzles are located outside the cylinder and spaced a considerable distance from the blades along the cylinder axis, the sprayed liquid cannot adequately cover the blade surface, resulting in poor cleaning effectiveness. Furthermore, the annular pipe presents challenges in installation and disassembly. Utility Model Content

[0023] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] The following is for reference. Figures 1-3 This invention describes a gas turbine with a cleaning function according to an embodiment of the present invention.

[0025] like Figures 1-3 As shown, the gas turbine with cleaning function in this embodiment of the present invention includes a rotor 1, blades 2, a cylinder 3 and a spraying mechanism 4.

[0026] The outer circumferential surface of the rotor 1 is provided with blades 2, and the cylinder 3 surrounds the outer circumference of the rotor 1 and blades 2. The cylinder 3 is provided with a mounting hole that penetrates the wall of the cylinder 3. The spraying mechanism 4 is detachably provided in the mounting hole and is used to spray cleaning medium into the space surrounding the cylinder 3.

[0027] like Figure 1 As shown, rotor 1 extends vertically and is rotatable about its center line extending vertically. Cylinder 3 is a ring extending vertically and arranged around the outer periphery of rotor 1. Cylinder 3 and rotor 1 are preferably, but not limited to, coaxially arranged. Blade 2 is connected to the outer peripheral surface of rotor 1 and located between rotor 1 and cylinder 3. Blade 2 is rotatable about the vertical direction under the drive of rotor 1.

[0028] The cylinder 3 is provided with a mounting hole that penetrates the wall of the cylinder 3 in a horizontal direction. The mounting hole is detachably connected to the spray mechanism 4 so that the spray mechanism 4 is installed in the wall of the cylinder 3 in a horizontal direction. One end of the spray mechanism 4 located in the space surrounding the cylinder 3 is the inner end, and the other end of the spray mechanism 4 located outside the cylinder 3 is the outer end. The outer end of the spray mechanism 4 is used to connect to the medium pipeline located outside the cylinder 3. The inner end of the spray mechanism 4 is provided with a nozzle. The spray cleaning medium supplied by the medium pipeline to the spray mechanism 4 is sprayed out from the nozzle into the space surrounding the cylinder 3.

[0029] Since the spraying mechanism 4 and the blades 2 are arranged radially along the rotor 1, the cleaning medium sprayed by the spraying mechanism 4 can diffuse from the tip of the blades 2 to the root of the blades 2, thereby covering the surface of the blades 2 with the cleaning medium to thoroughly clean the blades 2.

[0030] The gas turbine with cleaning function in this embodiment of the utility model has a cylinder 3 mounting hole that is detachably connected to a spray mechanism 4 so that a cleaning medium is sprayed into the cylinder 3 through the spray mechanism 4, thereby cleaning the blades 2 located in the cylinder 3 and achieving a good cleaning effect. At the same time, since the spray mechanism 4 is detachably installed, it is easy to disassemble and maintain.

[0031] It should be noted that when the spray mechanism 4 is cleaning the blade 2, the rotor 1 and the blade 2 can be stationary, or the rotor 1 can drive the blade 2 to rotate. Preferably, the rotor 1 drives the blade 2 to rotate, so that the blade 2 rotates relative to the spray mechanism 4 under the drive of the rotor 1, thereby making the cleaning medium sprayed by the spray mechanism 4 more fully and evenly cover the surface of the blade 2.

[0032] It should be noted that when the gas turbine is running, the spray mechanism 4 can be connected to the mounting hole or removed from the mounting hole.

[0033] In some embodiments, the spraying mechanism 4 includes a mounting base 41 and a spraying assembly 42. The spraying assembly 42 is used to spray the cleaning medium. The mounting base 41 is detachably disposed in the mounting hole. The spraying assembly 42 is disposed on the mounting base 41 and is rotatable relative to the mounting base 41 to adjust the spraying direction of the spraying assembly 42 relative to the mounting base 41.

[0034] like Figures 1-3 As shown, the spraying mechanism 4 includes a mounting base 41 and a spraying assembly 42. The mounting base 41 is detachably connected to the mounting hole. The spraying assembly 42 is connected to the mounting base 41 and passes through the mounting base 41 in a horizontal direction so as to pass through the mounting base 41 and be mounted on the wall of the cylinder 3. The outer end of the spraying assembly 42 is used to connect to a medium pipeline located outside the cylinder 3. The inner end of the spraying assembly 42 is provided with a nozzle to spray the cleaning medium supplied by the medium pipeline into the cylinder 3.

[0035] The spray assembly 42 is rotatable relative to the mounting base 41 to adjust the spray direction of the spray assembly 42 relative to the mounting base 41, thereby adjusting the spray angle of the spray assembly 42 relative to the blade 2 to ensure the cleaning effect of the blade 2.

[0036] It should be noted that the spray assembly 42 can be rotated in a controlled manner or manually. The spray assembly 42 can be rotated during the cleaning process or before cleaning.

[0037] In some embodiments, the spray assembly 42 includes a rotating seat 421 and a nozzle 422. The rotating seat 421 passes through the mounting base 41. The inner end of the rotating seat 421 is connected to the nozzle 422. The rotating seat 421 is provided with a medium channel 4211 communicating with the nozzle 422. The medium channel 4211 forms an opening at the outer end of the rotating seat 421. The outer end of the rotating seat 421 is used to connect a medium pipe for supplying cleaning medium. The rotating seat 421 includes a ball head 4212. The mounting base 41 is provided with a through ball head groove 411. The ball head 4212 is rotatably disposed in the ball head groove 411.

[0038] like Figure 2 and Figure 3 As shown, the spray assembly 42 includes a rotating seat 421 and a nozzle 422. The rotating seat 421 includes a ball head 4212. The mounting base 41 is provided with a ball head groove 411 that extends horizontally. The ball head 4212 is rotatably fitted in the ball head groove 411 so that the rotating seat 421 can rotate relative to the mounting base 41 and is inserted horizontally into the mounting base 41.

[0039] The inner end of the rotating seat 421, located inside the cylinder 3, is connected to the nozzle 422, which has a nozzle orifice. The outer end of the rotating seat 421, located outside the cylinder 3, is used to connect to the media pipeline. The rotating seat 421 has a media channel 4211 that runs horizontally through it. One end of the media channel 4211 is connected to the nozzle 422, and the other end forms an opening at the outer end of the rotating seat 421 to connect to the media pipeline, so as to guide the cleaning medium supplied by the media pipeline to the nozzle 422, thereby allowing the cleaning medium to be sprayed out from the nozzle orifice of the nozzle 422.

[0040] In some embodiments, the inner end of the ball head 4212 is provided with a slot, and the nozzle 422 is inserted into the slot. The rotating seat 421 also includes a connector 4213, which is located at the outer end of the ball head 4212. The medium channel 4211 passes through the ball head 4212 and the connector 4213 in sequence, and an opening is formed in the connector 4213. The connector 4213 is used to connect the medium pipeline.

[0041] like Figure 2 and Figure 3 As shown, the rotating seat 421 also includes a connector 4213, and a ball head 4212 is rotatably fitted in the ball head groove 411 and passes through the rotating seat 421.

[0042] The inner end of the ball head 4212 extending from the ball head groove 411 into the cylinder 3 is the inner end of the rotating seat 421. The inner end of the ball head 4212 is provided with a slot, and one end of the nozzle 422 is inserted into the slot and communicates with the medium channel 4211. Furthermore, the slot is provided with an internal thread, and one end of the nozzle 422 is provided with an external thread. The external thread is adapted to the internal thread so that one end of the nozzle 422 is threadedly connected to the slot.

[0043] The ball head 4212 extends from the ball head groove 411 to the outer end of the cylinder 3 and connects to the connector 4213. Preferably, the ball head 4212 and the connector 4213 are integrally connected, so that the outer end of the rotating seat 421 includes the outer end of the ball head 4212 and the connector 4213. The medium channel 4211 passes through the ball head 4212 and the connector 4213 in a horizontal direction, and forms an opening in the connector 4213. The connector 4213 is detachably connected to the medium pipeline, and the medium pipeline communicates with the opening.

[0044] Optionally, the medium pipeline is made of an elastic material, preferably but not limited to rubber. The outer diameter of the connector 4213 is larger than the inner diameter of the medium pipeline when it is not subjected to external force. The connector 4213 is inserted into the opening of the medium pipeline and causes the medium pipeline to expand and deform, so that the medium pipeline is fitted around the outer periphery of the connector 4213, and the medium pipeline is stably connected under the elastic force of deformation.

[0045] Optionally, the medium pipeline is made of a rigid material, preferably but not limited to metal or plastic. The pipe opening of the medium pipeline is provided with an internal thread, and the connector 4213 is provided with an external thread, so that the medium pipeline is fitted onto the outer circumference of the connector 4213 and threadedly connected.

[0046] Optionally, the medium pipeline is made of a rigid material, preferably but not limited to metal or plastic. The pipe opening of the medium pipeline is provided with an external thread, and the connector 4213 is provided with an internal thread, so that the medium pipeline is inserted into the opening of the connector 4213 and threadedly connected.

[0047] In some embodiments, the mounting base 41 is detachably snapped into the mounting hole.

[0048] like Figure 2 As shown, the mounting base 41 snaps into the mounting hole and is removable.

[0049] In some embodiments, at least the outer peripheral end of the mounting base 41 is elastically deformable, and the outer peripheral end of the mounting base 41 is provided with a groove 412 extending in the circumferential direction, and the wall of the mounting hole is engaged with the groove 412.

[0050] like Figure 2As shown, the mounting base 41 is preferably, but not limited to, made of an elastic material such as rubber, so that the mounting base 41 can be elastically deformed. The mounting base 41 has a groove 412 extending circumferentially along the outer peripheral surface in the horizontal direction. By pressing the mounting base 41 in the horizontal direction, the mounting base 41 can be pressed into the mounting hole, and the hole wall of the mounting hole can be engaged with the groove 412.

[0051] During the pressing process, because the mounting base 41 is elastically deformable, its outer peripheral end can contract under the pressure of the mounting hole wall when it abuts against the mounting hole wall. This allows the mounting hole wall to move horizontally along the outer peripheral surface of the mounting base 41 into the slot 412. The contracted portion of the outer peripheral end of the mounting base 41 can reset after engaging with the mounting hole wall in the slot 412, thereby confining the mounting hole wall within the slot 412.

[0052] Similarly, by pulling the mounting base 41 horizontally, the mounting base 41 can be disengaged from the mounting hole. This allows the mounting hole to be detachably engaged with the mounting hole, thereby allowing the spray mechanism 4 to be detachably mounted in the mounting hole.

[0053] It is understood that the mounting base 41 is not limited to being made entirely of elastic materials such as rubber. In some other embodiments, the mounting base 41 includes a body and an elastic layer. The elastic layer is preferably, but not limited to, being made of elastic materials such as rubber. The elastic layer is located on the outer periphery of the body, and the outer periphery of the elastic layer is provided with a groove 412.

[0054] In some embodiments, the spraying mechanism 4 further includes a gasket 43. The outer peripheral end of the mounting base 41 is provided with a slot 412, a card portion 413 and a gasket groove 414 arranged sequentially from the inside to the outside. The card portion 413 and the gasket groove 414 both extend along the circumferential direction of the mounting base 41. The card portion 413 can be tilted and deformed along the axial direction of the mounting base 41. The gasket 43 is disposed in the gasket groove 414 and abuts against the card portion 413 so that the card portion 413 abuts against the outer peripheral surface of the cylinder 3.

[0055] like Figure 2 As shown, the outer periphery of the mounting base 41 is provided with a slot 412, a card portion 413 and a gasket groove 414 arranged sequentially from the inside to the outside (in the direction from the radial direction of the cylinder 3, from the space surrounding the cylinder 3 to the outside of the cylinder 3). The card portion 413 and the gasket groove 414 also extend along the circumference of the mounting base 41.

[0056] The card portion 413 is part of the outer peripheral end of the mounting base 41, therefore the card portion 413 can also be elastically deformed so that the card portion 413 can be tilted in the horizontal direction. In other words, the card portion 413 extends in a direction away from the mounting base 41 and can tilt to the left or to the right under the action of external force. The left end face of the card portion 413 forms a card groove 412, and the right end face of the card portion 413 forms a gasket groove 414. Therefore, the position of the card portion 413 affects the width of the card groove 412 and the gasket groove 414 in the horizontal direction.

[0057] The gasket groove 414 is used to embed a number of gaskets 43 in the horizontal direction, and the number of gaskets 43 embedded in the gasket groove 414 is selectable. By adjusting the number of gaskets 43, the card portion 413 that is tilted to the left, tilted to the right, or extended vertically can abut against the wall of the mounting hole, so that the groove width of the card slot 412 is adapted to the wall thickness of the mounting hole, that is, the wall thickness of the cylinder 3, so that the wall of the mounting hole of different thicknesses can be stably engaged in the card slot 412, ensuring that the mounting base 41 is stably connected to the mounting hole.

[0058] Specifically, when the wall thickness of the mounting hole is greater than the thickness of the slot 412 when the card part 413 extends vertically, the wall of the mounting hole presses the card part 413 to tilt to the right. At this time, a smaller shim 43 with a total thickness less than the thickness of the shim slot 414 when the card part 413 extends vertically is embedded in the shim slot 414, so that the wall of the mounting hole, the card part 413 and the smaller shim 43 are tightly abutted and stably locked between the left wall of the slot 412 and the right wall of the shim slot 414.

[0059] When the wall thickness of the mounting hole is less than the thickness of the slot 412 when the card part 413 extends vertically, the wall of the mounting hole is spaced apart from the vertically extending card part 413. At this time, a larger number of gaskets 43 with a total thickness greater than the thickness of the gasket slot 414 when the card part 413 extends vertically are embedded in the gasket slot 414. The larger number of gaskets 43 press the card part 413 to tilt to the left and abut against the wall of the mounting hole, so that the wall of the mounting hole, the card part 413 and the smaller number of gaskets 43 are tightly abutted and stably locked between the left wall of the slot 412 and the right wall of the gasket slot 414.

[0060] When the wall of the mounting hole is equal to the thickness of the slot 412 when the card part 413 extends vertically, a number of shims 43 with a total thickness equal to the thickness of the shim slot 414 when the card part 413 extends vertically are embedded in the shim slot 414, so that the wall of the mounting hole, the card part 413 and a few shims 43 are tightly abutted and stably locked between the left wall of the slot 412 and the right wall of the shim slot 414.

[0061] In some embodiments, the outer peripheral surface of the cylinder 3 is provided with a boss 31 surrounding the mounting hole, and the mounting seat 41 is provided in the mounting hole and connected to the boss 31 through a connector 5.

[0062] like Figure 1 and Figure 3 As shown, cylinder 3 is an annular structure extending vertically and arranged around the vertical direction. A boss 31 is provided on the outer circumferential surface of cylinder 3, and the boss 31 is annular and surrounds the outer periphery of the mounting hole. Mounting seat 41 is located in the mounting hole and is detachably connected to the boss 31 via connector 5.

[0063] In some embodiments, the outer end of the mounting base 41 is provided with a flange portion 415 arranged circumferentially, the flange portion 415 abuts against the boss 31 and is connected to it by the connector 5.

[0064] like Figure 3 As shown, the left end of the mounting base 41 is located inside the mounting hole, and the right end of the mounting base 41 is provided with a flange portion 415 extending circumferentially along the mounting base 41. The flange portion 415 is located outside the mounting hole and abuts against the right end face of the boss 31. Connecting parts 5, such as bolts, are horizontally arranged and connect the flange portion 415 to the boss 31.

[0065] Preferably, the connectors 5 are a plurality of connectors arranged at intervals along the circumference of the flange portion 415.

[0066] It is understood that the connector 5 is not limited to connecting the flange 415 and the boss 31. In some other embodiments, the outer peripheral surface of the mounting base 41 is provided with a pin hole, and the boss 31 is provided with a through hole. The connector 5 is preferably, but not limited to, a positioning pin. The positioning pin passes through the through hole and is inserted into the pin hole to detachably connect the mounting base 41 to the boss 31 and to the mounting hole.

[0067] In some embodiments, the blades 2 are arranged in multiple rows along the axial direction of the rotor 1, each row having multiple blades 2 spaced apart along the circumferential direction of the rotor 1, and the spacing between at least some adjacent rows of blades 2 is corresponding to the spray mechanism 4.

[0068] like Figure 1 As shown, the rotor 1 extends vertically and can rotate around the vertical direction. The outer circumference of the rotor 1 is provided with multiple rows of blades 2 arranged at intervals along the vertical direction. Each row of blades 2 includes multiple blades 2 arranged at intervals along the circumference of the rotor 1. The blade lengths of the multiple rows of blades 2 in the horizontal direction can be the same or different. Preferably, the blade lengths of the multiple rows of blades 2 increase from top to bottom.

[0069] The cylinder 3 is equipped with at least two spray mechanisms 4 arranged vertically at intervals. The interval between each pair of adjacent rows of blades 2 corresponds to a spray mechanism 4, or the interval between some pairs of adjacent rows of blades 2 corresponds to a spray mechanism 4. The spray mechanism 4 can extend into the corresponding interval space or be located outside the corresponding interval space. This ensures that the cleaning medium sprayed by the spray mechanism 4 can at least cover the front surface of one row of blades 2 forming the corresponding interval space and the back surface of the other row of blades 2.

[0070] Furthermore, the cylinder 3 is provided with a multi-row spray mechanism 4, which is arranged at intervals along the circumference of the cylinder 3. Each row includes at least two spray mechanisms 4 arranged at intervals along the vertical direction. The vertical height positions of the spray mechanisms 4 in each row can be the same, so that the multi-row spray mechanisms 4 spray cleaning medium into the same interval space. The vertical height positions of the spray mechanisms 4 in each row can also be different, so that the multi-row spray mechanisms 4 spray cleaning medium into different interval spaces.
