Description

Technical Field

[0001] This application relates to the technical field of cleaning equipment, and particularly to a cleaning device for a compressor of a gas turbine. Background Art

[0002] After a gas turbine compressor is used for a period of time, the surface of the blades will be fouled, resulting in a reduction in the output power of the gas turbine. If the surface of the compressor blades is fouled, the compressor blades need to be cleaned to restore the performance of the compressor. During cleaning, water or cleaning liquid with a certain pressure and temperature is injected into the cleaning pipeline of the compressor. The water or cleaning liquid will flow through the cleaning pipeline of the compressor to each nozzle and be sprayed onto the surface of the compressor blades, thereby completing the cleaning.

[0003] It should be noted that during the cleaning process, different types of gas turbines have different requirements for the cleaning flow rate. If the cleaning flow rate is too large, it is difficult for the water or cleaning liquid to flow out from the inside of the compressor, that is, the water or cleaning liquid will accumulate inside the compressor, and thus it is easy to cause the lubricating oil in the bearing cavity of the compressor to be contaminated; if the cleaning flow rate is too small, it is difficult to wash the compressor blades clean. Therefore, the existing cleaning devices for compressors of gas turbines can only be applicable to a certain model of gas turbine and are difficult to be applicable to different models of gas turbines, that is, the versatility is poor.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0036] It should be noted that in the description of the present application, the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0037] In addition, it should be understood that for the convenience of description, the sizes of the various components shown in the drawings are not drawn according to the actual proportional relationship. For example, the thickness or width of some layers may be exaggerated relative to other layers.

[0038] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined or described in one drawing, it will not be necessary to further discuss and describe it specifically in the description of the subsequent drawings.

[0039] In order to solve the technical problem of the poor universality of the existing cleaning device for the compressor of a gas turbine proposed in the background art, an embodiment of a cleaning device for the compressor of a gas turbine is proposed in the present application. It should be noted that in this embodiment, the compressor includes a cleaning pipeline. Since the compressor with a cleaning pipeline is a mature technology, it will not be elaborated too much. Specifically, the cleaning device in this embodiment includes a water tank 1, a water outlet pipe 6, a water pump 2, a first return pipe 14, and a flow adjustable valve 15. Among them, as Figure 1 shown, the water tank 1 is used to store the cleaning liquid. The water outlet pipe 6 is used to guide the cleaning liquid to the cleaning pipeline of the compressor. That is to say, during use, the water outlet pipe 6 is connected to the cleaning pipeline of the compressor. The inlet end of the water pump 2 can be at least connected to the water tank 1, and the outlet end of the water pump 2 can be at least connected to the water outlet pipe 6. That is to say, during use, the water pump 2 pumps the cleaning liquid in the water tank 1 to the water outlet pipe 6, and the water outlet pipe 6 then guides the cleaning liquid to the cleaning pipeline of the compressor, thereby realizing the cleaning of the compressor blades. One end of the first return pipe 14 is connected to the water outlet pipe 6, and the other end of the first return pipe 14 is connected to the water tank 1. The flow adjustable valve 15 is arranged on the first return pipe 14.

[0040] It should be noted that, in the embodiments of the present application, the flow rate of the cleaning liquid at the outlet end of the water pump 2 is equal to the sum of the flow rate of the cleaning liquid in the outlet pipe 6 and the flow rate of the cleaning liquid in the first return pipe 14. Without changing the water pump 2, that is, the flow rate of the cleaning liquid at the outlet end of the water pump 2 is constant. That is to say, if the flow rate of the cleaning liquid in the first return pipe 14 increases, the flow rate of the cleaning liquid in the outlet pipe 6 decreases; if the flow rate of the cleaning liquid in the first return pipe 14 decreases, the flow rate of the cleaning liquid in the outlet pipe 6 increases. In other words, the embodiments of the present application can adjust the flow rate of the cleaning liquid in the first return pipe 14 through the flow rate adjustable valve 15, thereby controlling the flow rate of the cleaning liquid in the outlet pipe 6. When in use, the size of the flow rate of the cleaning liquid in the outlet pipe 6 can be adjusted according to the model of the gas turbine, that is, the size of the flow rate of the cleaning liquid in the compressor cleaning pipeline is adjusted. Since the cleaning device for the compressor of the gas turbine proposed in the embodiments of the present application can adjust the flow rate of the cleaning liquid based on the actual cleaning requirements of the gas turbine, the cleaning device for the compressor of the gas turbine has strong versatility.

[0041] In the embodiments of the present application, the flow rate adjustable valve 15 can be any valve that can control the flow rate in the first return pipe 14. For example, the flow rate adjustable valve 15 can be a butterfly valve with a scale, a ball valve or a needle valve, etc.

[0042] In the embodiments of the present application, no restrictions are imposed on the composition of the cleaning liquid. For example, the cleaning liquid can be clean water, or the cleaning liquid is a mixed liquid formed by water and a cleaning agent.

[0043] It should be noted that if foreign impurities enter the interior of the water tank 1, it will cause pollution to the cleaning liquid inside the water tank 1 at least, and at worst, the impurities will damage the compressor blades along with the cleaning liquid (such as hard particles or salt mist, etc.). In order to prevent foreign impurities from entering the water tank 1, in an embodiment of the present application, the water tank 1 can be designed as a sealed tank structure. If the water tank 1 is designed as a sealed tank structure, then as Figure 2 shown, a first filter 7 is also required in the water tank 1, and the first filter 7 is used to filter the air entering the water tank 1.

[0044] In the embodiments of the present application, the first filter 7 only needs to be able to filter air, and no restrictions are imposed on the type and structure of the first filter 7. For example, the first filter 7 can be a cartridge filter or an air filter.

[0045] In the case where the water tank 1 is a sealed tank structure, in order to facilitate the injection of the cleaning liquid into the water tank 1, in an embodiment of the present application, the cleaning device further includes a water injection pipe 5. Specifically, as Figure 2As shown in the figure, a first three-way valve 3 is provided at the water inlet end of the water pump 2. The water inlet end of the water pump 2 can be connected to the water injection pipe 5 or the water tank 1 through the first three-way valve 3. A second three-way valve 4 is provided at the water outlet end of the water pump 2. The water outlet end of the water pump 2 can be connected to the water outlet pipe 6 or the water tank 1 through the second three-way valve 4. During use, if it is necessary to inject cleaning liquid into the water tank 1, the water injection pipe 5 is connected to a container storing the cleaning liquid (for example: storage pool or storage tank, etc.). And the water inlet end of the water pump 2 is connected to the water injection pipe 5 through the first three-way valve 3; the water outlet end of the water pump 2 is connected to the water tank 1 through the second three-way valve 4. If the water pump 2 is turned on, the water pump 2 can pump the cleaning liquid in the container into the water tank 1. During use, if it is necessary to transport the cleaning liquid in the water tank 1 to the cleaning pipeline of the compressor, the water outlet pipe 6 is connected to the cleaning pipeline. And the water inlet end of the water pump 2 is connected to the water tank 1 through the first three-way valve 3; the water outlet end of the water pump 2 is connected to the water outlet pipe 6 through the second three-way valve 4. If the water pump 2 is turned on, the water pump 2 can transport the cleaning liquid in the water tank 1 to the cleaning pipeline of the compressor.

[0046] In order to prevent the cleaning liquid in the container from carrying impurities into the water tank 1, or the cleaning liquid in the water tank 1 from carrying impurities into the interior of the compressor, in an embodiment of the present application, as Figure 2 shown, a second filter 13 is further provided at the water outlet end of the water pump 2. It is easy to understand that the second filter 13 can filter the cleaning liquid entering the water tank 1 and can also filter the cleaning liquid entering the cleaning pipeline of the compressor.

[0047] In the embodiment of the present application, no restrictions are imposed on the shape and structure of the second filter 13. For example, the second filter 13 can be a cartridge filter or a Y-type filter.

[0048] During long-term use, dirt will definitely accumulate inside the water tank 1. In order to be able to flush out the dirt inside the water tank 1, in an embodiment of the present application, as Figure 2 shown, the water tank 1 can also be provided with a sewage discharge pipe 11, and a sewage discharge valve 12 is provided on the sewage discharge pipe 11. If it is necessary to clean the dirt inside the water tank 1, the sewage discharge valve 12 is opened, and the dirt inside the water tank 1 can flow out of the water tank 1 through the sewage discharge pipe 11. If it is necessary to flush the compressor blades, the sewage discharge valve 12 is closed to prevent the cleaning liquid in the water tank 1 from flowing out of the water tank 1 through the sewage discharge pipe 11.

[0049] In order to facilitate the movement of the cleaning device for the compressor of the gas turbine proposed in the embodiment of the present application, in an embodiment of the present application, the cleaning device further includes a housing 19, a handle 26 and a plurality of wheels 20. Specifically, as Figure 3 and Figure 4As shown, the water tank 1 is arranged inside the housing 19, multiple wheels 20 are arranged at the bottom of the housing 19, and the handle 26 is arranged on the housing 19. That is to say, in this embodiment, the user can move the water tank 1 to a preset use position on the ground through the handle 26 and the wheels 20. To facilitate fixing the spatial position of the housing 19, the wheels 20 can be wheels that can be braked.

[0050] When the water tank 1 is of a sealed tank structure, that is, it is impossible to visually know whether the water tank 1 is filled with cleaning liquid. In order to avoid injecting excessive cleaning liquid into the water tank 1, in an embodiment of the present application, as Figure 3 shown, the housing 19 can also be provided with an electric control box 24. The cleaning device can also include a liquid level sensor 9, the liquid level sensor 9 is arranged inside the water tank 1, and both the liquid level sensor 9 and the water pump 2 are electrically connected to the electric control box 24. During use, if the liquid level sensor 9 detects that the liquid level of the cleaning liquid in the water tank 1 reaches a preset value, the electric control box 24 can directly turn off the water pump 2, thereby avoiding excessive injection of cleaning liquid into the water tank 1. It should be clear that the liquid level sensor 9 transmits the liquid level signal to the electric control box 24, and the electric control box 24 turns off the water pump 2 based on the liquid level signal are all mature technologies and will not be elaborated here.

[0051] In order to avoid the cleaning device for the compressor of the gas turbine being abnormal (for example, the water pump 2 is abnormal or the water outlet pipe 6 is blocked, etc.), resulting in excessive pressure on the water outlet pipe 6 or related parts and causing damage, in an embodiment of the present application, the cleaning device also includes a second return pipe 18, a pressure gauge 16 and a safety valve 17. Among them, as Figure 2 shown, one end of the second return pipe 18 is communicated with the water outlet pipe 6, and the other end of the second return pipe 18 is communicated with the water tank 1. The pressure gauge 16 and the safety valve 17 are both arranged on the second return pipe 18, and both the pressure gauge 16 and the safety valve 17 are electrically connected to the electric control box 24. During use, if the pressure gauge 16 detects that the pressure in the water outlet pipe 6 is too high, the electric control box 24 can directly open the safety valve 17. If the safety valve 17 is opened, the cleaning liquid in the water outlet pipe 6 can return to the water tank 1 through the second return pipe 18. That is to say, this embodiment can avoid the phenomenon that the pressure of the water outlet pipe 6 is too high and damage the water outlet pipe 6 or other related parts when the cleaning device for the compressor of the gas turbine is abnormal. It should be clear that the pressure gauge 16 transmits the pressure signal to the electric control box 24, and the electric control box 24 controls the safety valve 17 to open based on the pressure signal are all mature technologies and will not be elaborated here.

[0052] It should be noted that some cleaning agents can only achieve the best effect at a specific temperature, for example: alkaline cleaning agents, NH3 cleaning agents or HCl cleaning agents, etc. In order to make the cleaning liquid in the water tank 1 at the best use temperature, in an embodiment of the present application, the cleaning device can also include a temperature sensor 8 and a heater 10. Among them, asFigure 2 As shown, a temperature sensor 8 is disposed inside the water tank 1 and is electrically connected to the electric control box 24. A heater 10 is disposed inside the water tank 1 and is also electrically connected to the electric control box 24. During use, if the temperature of the cleaning liquid in the water tank 1 does not reach the optimal operating temperature, the heater 10 can be turned on to heat the cleaning liquid. If the temperature of the cleaning liquid in the water tank 1 reaches the optimal operating temperature, the electric control box 24 can directly turn off the heater 10. It should be noted that the temperature sensor 8 transmits temperature signals to the electric control box 24, and the electric control box 24 turns off the heater 10 based on the temperature signals, which are all mature technologies and will not be elaborated here.

[0053] In order to supply power to each electrically-powered component (such as the electric control box 24 or the water pump 2, etc.) in the cleaning device for the compressor of a gas turbine proposed in the embodiments of the present application, as Figure 3 shown, the cleaning device may further include a power interface 25, and the power interface 25 is electrically connected to each component through wires. Since the power interface 25 is electrically connected to each component through wires is a mature technology, it will not be elaborated here. During use, the power interface 25 can be connected to an external power source (such as: a storage battery or a two-phase or three-phase power of a power supply network, etc.), so that each electrically-powered component of the cleaning device can be powered on.

[0054] It should be noted that when the cleaning device for the compressor of a gas turbine in this embodiment is in use, some tools may be used, such as: a connecting pipe connecting the outlet pipe 6 and the compressor cleaning pipeline or a power cord connecting the power interface 25 and the external power source, etc. In order to facilitate the storage of these tools to avoid loss, in an embodiment of the present application, as Figure 3 shown, the housing 19 may further be provided with a storage compartment 21 and a hatch 22. The hatch 22 is hinged to the housing 19 and is used to open and close the storage compartment 21. After using the cleaning device, the above-mentioned tools can be placed in the storage compartment 21. Before the next use, the above-mentioned tools can be taken out from the storage compartment 21, thereby avoiding the loss of these tools due to improper storage.

[0055] In order to facilitate the user's observation and maintenance of the condition of the water tank 1, in an embodiment of the present application, as Figure 3 shown, a water tank access door 23 may further be provided on the housing 19. If it is necessary to observe or maintain the water tank 1, the water tank access door 23 can be opened. In order to facilitate the user's observation and maintenance of the above-mentioned pipelines and circuits, in an embodiment of the present application, as Figure 4 shown, a pipeline access door 27 may further be provided on the housing 19. If it is necessary to observe or maintain the pipelines and circuits, the pipeline access door 27 can be opened.

[0056] It should be clear that the cleaning device for the compressor of a gas turbine proposed in this application can adjust the flow rate of the cleaning liquid entering the compressor cleaning pipeline based on the first return pipe and the flow rate adjustable valve. That is to say, this application can adjust the flow rate of the cleaning liquid based on the actual cleaning requirements of the gas turbine, which means that the cleaning device for the compressor of the gas turbine proposed in this application has strong versatility.

[0057] Although the embodiments of this application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of this application.
