Description

Technical Field

[0001] The present invention relates to the technical field of gas turbine blade cleaning, and particularly to an automatic gas turbine blade cleaning device for a gas turbine power plant. Background Technique

[0002] A gas turbine is an internal combustion power machine that uses continuously flowing gas as the working medium to drive the impeller to rotate at high speed and convert the energy of fuel into useful work. It is a rotary impeller type heat engine. In the main processes of air and gas, the gas turbine cycle composed of only three major components, namely a compressor, a combustion chamber, and a gas turbine, is generally referred to as a simple cycle.

[0003] The compressor sucks in air from the external atmospheric environment and compresses it step by step through an axial-flow compressor to increase its pressure. At the same time, the air temperature also increases accordingly; the compressed air is sent to the combustion chamber to be mixed with the injected fuel and burned to generate high-temperature and high-pressure gas; then it enters the turbine to expand and do work, driving the turbine to drive the compressor and the external load rotor to rotate at high speed together, realizing the partial conversion of the chemical energy of gas or liquid fuel into mechanical work and outputting electric power. The initial gas temperature and the compression ratio of the compressor are two main factors affecting the efficiency of the gas turbine. Increasing the initial gas temperature and correspondingly increasing the compression ratio can significantly improve the efficiency of the gas turbine.

[0004] In the prior art, when the blades in the compressor chamber of a gas turbine rotate, they will bring in dust and impurities in the air together. And during long-term operation or when idle, more dust and impurities will adhere to the surface of the blades, thus affecting the flow of air on the blade surface, and corrosive impurities will cause the risk of blade corrosion, resulting in a reduction in the efficiency of the gas turbine. Usually, nozzles are installed on the inner wall of the compressor, and cleaning liquid is sprayed onto the surface of the blades through the nozzles to clean the impurities attached to the blades. And the cleaning liquid needs to be heated before being filled into the cylinder to improve the cleaning effect. However, this will increase the cleaning steps and reduce the cleaning efficiency. Moreover, the gas turbine has high waste heat during exhaust, but it cannot be used in cooperation with the cleaning work, resulting in waste of resources. For this reason, we propose an automatic gas turbine blade cleaning device for a gas turbine power plant. Summary of the Invention

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment 1

[0038] Please refer to Figures 1 - 6 , an automatic cleaning device for gas turbine blades in a gas turbine power plant shown in the figure, including:

[0039] A gas turbine body 1, blades, and a fixing frame 2 at the bottom of the gas turbine body 1;

[0040] It further includes:

[0041] A liquid storage cylinder 3, the liquid storage cylinder 3 is fixed on the top surface of the fixing frame 2, an annular conduit 4 is sleeved around the periphery of the gas turbine body 1 corresponding to the compressor position, a spray head 5 cooperating with the blades is fixedly installed on the outer surface of the annular conduit 4 corresponding to the inner wall of the gas turbine body 1, a water pump 6 is fixedly installed on the outer surface of the liquid storage cylinder 3, and a connecting pipe 7 communicating with the annular conduit 4 is fixed at the water outlet end of the water pump 6;

[0042] An exhaust vent pipe 8, the exhaust vent pipe 8 is fixed at the exhaust end of the gas turbine body 1, a treatment box 9 is fixed at the end of the exhaust vent pipe 8, air outlet pipes 10 are fixedly installed on both the top surface and the bottom surface of the treatment box 9, a heat conduction mechanism cooperating with the treatment box 9 is arranged on the outer surface of the liquid storage cylinder 3, the heat conduction mechanism is used for heating the liquid storage cylinder 3, filter plates 11 are fixedly installed on the inner top wall and the inner bottom wall of the treatment box 9 corresponding to the air outlet pipes 10, and a cleaning mechanism is arranged inside the treatment box 9, and the cleaning mechanism is used for cleaning the filter plates 11.

[0043] It should be noted that the liquid inlet end of the water pump 6 is communicated with the inside of the liquid storage cylinder 3. The exhaust gas of the gas turbine body 1 is recycled through the heat conduction mechanism, so as to heat the cleaning liquid, thereby improving the cleaning effect of the cleaning liquid; and the cleaning mechanism cleans the dust and impurities attached to the surface of the filter plates 11 to keep the air flow unobstructed.

[0044] Furthermore, as shown in Figure 2 , Figure 3 and Figure 4 , it is specifically noted that the heat conduction mechanism includes:

[0045] The heat preservation sleeve 12 is fixedly sleeved on the outer surface of the liquid storage cylinder 3. A spiral heat conduction tube 13 is wound around the outer surface of the liquid storage cylinder 3. The spiral heat conduction tube 13 is located inside the heat preservation sleeve 12. One end of the spiral heat conduction tube 13 is fixed with an air inlet pipe 14, and the other end of the spiral heat conduction tube 13 is fixed with an exhaust pipe 15. The end of the air inlet pipe 14 is fixedly connected to the bottom surface of the air outlet pipe 10 at the lower end, and the end of the exhaust pipe 15 is fixedly connected to the outer surface of the air outlet pipe 10 at the upper end. A thermometer 16 is inserted into the top surface of the liquid storage cylinder 3 corresponding to the cleaning liquid;

[0046] The opening and closing assembly is arranged on the outer surface of the processing box 9, and the opening and closing assembly is used to control the air output of the two air outlet pipes 10.

[0047] It should be noted that the remaining gas enters the air inlet pipe 14 through the air outlet pipe 10, and then enters the spiral heat conduction tube 13, so as to heat the liquid storage cylinder 3. By observing the thermometer 16, the temperature of the cleaning liquid is heated to 40 to 50 degrees, and then the water pump 6 is started, so that the cleaning liquid enters the annular conduit 4 and finally sprays out from the nozzle 5, so as to clean the blades. The waste liquid after cleaning is discharged from the fixed sewage outlet.

[0048] Furthermore, as Figure 2 and Figure 4 shown, specifically, the opening and closing assembly includes:

[0049] Two L-shaped fixing plates 17 are arranged and are respectively fixed on one side of the processing box 9. A threaded rod 18 penetrates through one side of the L-shaped fixing plate 17 in a threaded manner. The end of the threaded rod 18 is rotatably connected to a baffle 19. The baffle 19 is inserted into the surface of the processing box 9. The baffle 19 is located between the air outlet pipe 10 and the processing box 9.

[0050] It should be noted that by rotating the threaded rod 18, the baffle 19 is pushed to move horizontally. When the thermometer 16 shows that the temperature is too high, the baffle 19 reduces the exhaust volume of the air outlet pipe 10 at the lower end, achieving the effect of reducing the temperature. When cleaning is not required, the air outlet pipe 10 at the lower end can be completely closed.

[0051] Furthermore, as Figure 2 、 Figure 4 、 Figure 5 and Figure 6 shown, specifically, the cleaning mechanism includes:

[0052] The mounting bracket 20 is fixed to one side of the processing box 9. A driving motor 21 is fixed inside the mounting bracket 20. The output end of the driving motor 21 is coaxially connected to a rotating shaft 22. A turntable 23 is fixed to the end of the rotating shaft 22 corresponding to the inner wall of the processing box 9. A rotating rod 24 is fixed to the surface edge of the turntable 23. A movable frame 25 is sleeved on the outer surface of the rotating rod 24. A limiting rod 26 is fixed to one side of the movable frame 25. The end of the limiting rod 26 movably penetrates through the processing box 9. Ceramic fiber brushes 27 that cooperate with the air filter plate 11 are fixedly installed at both the top and bottom of the movable frame 25.

[0053] The stirring assembly is arranged between the liquid storage cylinder 3 and the processing box 9 and cooperates with the cleaning mechanism. The stirring assembly is used for stirring the cleaning liquid in the liquid storage cylinder 3.

[0054] It should be noted that the driving motor 21 drives the rotating shaft 22 to rotate, and then drives the turntable 23 to rotate inside the processing box 9, so that the rotating rod 24 presses the movable frame 25. The movable frame 25 is limited by the limiting rod 26, so that the movable frame 25 moves horizontally back and forth, thereby driving the two ceramic fiber brushes 27 to move and cleaning the dust and impurities attached to the surface of the air filter plate 11, reducing the entry of dust and impurities into the spiral heat conduction tube 13, avoiding the reduction of heat conduction efficiency due to the attachment of dust and impurities on the inner wall of the spiral heat conduction tube 13; at the same time, reducing the direct discharge of dust and impurities outdoors.

[0055] Embodiment 2

[0056] On the basis of Embodiment 1, according to Figure 1 、 Figure 2 and Figure 4 shown, it should be specifically noted that the stirring assembly includes:

[0057] The stirring rod 28 is rotatably installed in the liquid storage cylinder 3. An L-shaped fixing seat 29 is fixed to the outer surface of the processing box 9. A first connecting shaft 30 is rotatably connected inside the L-shaped fixing seat 29. Support rods 31 are fixed to the outer surfaces of the gas turbine body 1 and the processing box 9. A second connecting shaft 32 is rotatably connected inside the two support rods 31. A first bevel gear 33 is fixedly sleeved on the outer surface of the rotating shaft 22. Second bevel gears 34 are fixed to both ends of the first connecting shaft 30. One of the second bevel gears 34 is meshed and driven with the first bevel gear 33. Third bevel gears 35 are fixed to both ends of the second connecting shaft 32. The other second bevel gear 34 is meshed and driven with one of the third bevel gears 35. A fourth bevel gear 36 is fixed to the top end of the stirring rod 28. The fourth bevel gear 36 is meshed and driven with the other third bevel gear 35.

[0058] It should be noted that when the rotating shaft 22 rotates, it drives the second bevel gear 34 to rotate through the first bevel gear 33, causing the first connecting shaft 30 to rotate within the L-shaped fixed seat 29. Thus, the second bevel gear 34 drives the third bevel gear 35 to rotate, enabling the second connecting shaft 32 to rotate within the support rod 31. Consequently, the third bevel gear 35 drives the fourth bevel gear 36 to rotate, further driving the stirring rod 28 to rotate within the liquid storage cylinder 3, making the cleaning liquid heat more evenly.

[0059] Furthermore, as Figure 2 and Figure 4 shown, it is specifically noted that discharge pipes 37 are fixed on both sides of the bottom surface of the treatment box 9. A discharge valve 38 is fixedly installed on the outer surface of the discharge pipes 37. The cleaned debris is collected through the discharge pipes 37 and discharged by opening the discharge valve 38. A fixing rod 39 is fixed on the outer surface of the treatment box 9, and a limiting ring 40 is fixed at the end of the fixing rod 39. The limiting ring 40 is fixedly sleeved on the outer surface of the upper end air outlet pipe 10, which limits the air outlet pipe 10 to maintain the stability of the air outlet pipe 10 during exhaust.

[0060] Furthermore, as Figure 2 、 Figure 4 and Figure 5 shown, it is specifically noted that a liquid inlet pipe 41 is fixed on one side of the top surface of the liquid storage cylinder 3, and a liquid discharge pipe 42 is fixed at the lower end of the outer surface of the liquid storage cylinder 3. The liquid inlet pipe 41 and the liquid discharge pipe 42 facilitate the liquid addition and waste liquid discharge of the liquid storage cylinder 3 respectively. A rectangular groove 43 is formed on the outer surface of the treatment box 9, and a box door 44 is fixed to the inner wall of the rectangular groove 43 by bolts. By opening the box door 44, the air filter plate 11 inside the treatment box 9 can be replaced regularly, facilitating maintenance. A turning handle 45 is fixed at the end of the threaded rod 18, which facilitates the rotation of the threaded rod 18.

[0061] This embodiment also has the following working process: The surplus gas of the gas turbine body 1 enters the intake pipe 14 through the exhaust pipe 10 at the lower end, and then passes through the spiral heat-conducting pipe 13, so that the spiral heat-conducting pipe 13 heats the liquid storage cylinder 3, thereby increasing the temperature of the cleaning liquid. Then the gas enters the exhaust pipe 10 at the upper end from the exhaust pipe 15 and is discharged. The driving motor 21 drives the rotating shaft 22 to rotate, and then drives the turntable 23 to rotate inside the processing box 9, so that the rotating rod 24 presses the movable frame 25, and the movable frame 25 is limited by the limiting rod 26, so that the movable frame 25 moves horizontally back and forth, thereby driving the two ceramic fiber brushes 27 to move and cleaning the dust and impurities attached to the surface of the air filter plate 11, reducing the entry of dust and impurities into the spiral heat-conducting pipe 13, and avoiding the reduction of the heat conduction efficiency due to the attachment of dust and impurities on the inner wall of the spiral heat-conducting pipe 13; at the same time, it reduces the direct discharge of dust and impurities outdoors. By rotating the threaded rod 18, the baffle 19 is pushed to move horizontally. When the thermometer 16 shows that the temperature is too high, the baffle 19 reduces the exhaust volume of the exhaust pipe 10 at the lower end to achieve the effect of reducing the temperature. When cleaning is not required, the exhaust pipe 10 at the lower end can be completely closed. When the rotating shaft 22 rotates, the first bevel gear 33 drives the second bevel gear 34 to rotate, so that the first connecting shaft 30 rotates in the L-shaped fixed seat 29, thereby driving the third bevel gear 35 to rotate through the second bevel gear 34, so that the second connecting shaft 32 rotates in the support rod 31, thereby driving the fourth bevel gear 36 to rotate through the third bevel gear 35, and then driving the stirring rod 28 to rotate in the liquid storage cylinder 3, making the cleaning liquid heat more evenly. By observing the thermometer 16, the temperature of the cleaning liquid is heated to 40 to 50 degrees, and then the water pump 6 is started, so that the cleaning liquid enters the annular conduit 4 and finally sprays out from the nozzle 5, thereby cleaning the blades. The waste liquid after cleaning is discharged from the fixed sewage outlet.

[0062] The water pump 6 and the driving motor 21 can be purchased on the market and are equipped with power supplies, which are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.
