Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of filtering equipment, in particular to a multi-stage separation type filtering equipment for gas turbine intake. BACKGROUND

[0002] The gas turbine is an internal combustion power machine which uses continuous flow gas as working medium to drive impeller to rotate at high speed and convert fuel energy into useful work. It is a rotary impeller type heat engine. When the gas turbine body is working, the gas extracted by the gas turbine body intake pipeline must be kept clean to avoid the dust, sand, salt, water droplets, oil mist, insects or other impurity particles carried by the extracted gas from entering the gas turbine body, which may cause damage to the high-speed rotating core components such as compressor blades and worm wheel blades in the gas turbine body. Therefore, in order to ensure the normal operation of the gas turbine body, a filtering equipment is needed to filter the extracted gas.

[0003] The existing gas turbine body generally installs filters (such as filter cartridges, filter bags and filter plates) in the intake pipeline to filter the extracted gas. However, after a long time of use, the filters will continuously intercept impurity particles of different sizes. With the accumulation of time, these particles will continuously accumulate on the surface of the filter material and in the filter holes, forming an accumulation layer, which may cause the filter holes of the filter to be blocked, thereby limiting the intake flow, causing the intake of the gas turbine body to be insufficient, and further causing the output power of the gas turbine body to decrease. Long time use may cause the gas turbine body to appear protective shutdown. Therefore, in order to maintain the performance and safe operation of the gas turbine body, the installed filter often needs to be replaced or disassembled and cleaned frequently.

[0004] When the filter needs to be replaced and installed in the intake pipeline for a long time, the filter is usually disassembled and taken out from the top of the intake pipeline. This operation may cause the disassembly tool or impurities generated during disassembly to fall into the intake pipeline and then enter the gas turbine. In addition, during the interval between taking out the old filter and installing the new filter, the dust located at the top of the gas turbine may fall into the intake pipeline due to gravity and directly enter the gas turbine, which may cause damage to the blades.

DETAILED DESCRIPTION

[0033] The above and other technical contents, features and effects of the present invention are described below with reference to the attached Figures 1 to 12 The details of the embodiments will be clearly presented. The contents mentioned in the following embodiments are all based on the accompanying drawings.

[0034] Various exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

[0035] The present invention is an intake multi-stage separation filtering device for a gas turbine. The extracted gas is filtered by installing a filter 4 in the intake pipe 2 in the existing gas turbine body 1. Impurities of different sizes will form an accumulation layer on the filter port of the filter 4, resulting in the need to frequently replace the filter 4.

[0036] Furthermore, when the filter 4 is replaced, the disassembly tools used for replacement or impurities generated during disassembly will fall into the gas turbine body 1 in the intake duct 2, and when the top of the intake duct 2 is open, the dust above the intake duct 2 will enter the intake duct 2 due to gravity.

[0037] As an example, Figures 1 to 4 、 Figure 7 and Figure 8As shown, the present invention includes a gas turbine body 1 and an air intake duct 2, a protective net 3 is fixedly connected to the top of the air intake duct 2, a "V"-shaped filter 4 is fixedly connected to the air intake duct 2, and filter ports 5 are provided on both sides of the filter 4. The filter ports 5 are located on both sides of the filter 4, so that a "V"-shaped space is formed at the bottom of the filter 4, and a support frame 6 is fixedly connected to the filter 4. Two rotating shafts 7 are rotatably connected to the support frame 6. The bottoms of the two rotating shafts 7 are fixedly connected to push rods 9. The other ends of the two push rods 9 are rotatably connected to a fixing seat 10. The fixing seat 10 is hourglass-shaped. The filter 4 is in the shape of a filter element, and the two fixing seats 10 are fixedly connected with a pull rope 11. The first sliding frame 12 and the second sliding frame 13 are fixedly connected in the filter 4. The two pull ropes 11 respectively penetrate into one side of the first sliding frame 12 and the second sliding frame 13. The first sliding frame 12 and the second sliding frame 13 are located on both sides below the support frame 6. The first sliding frame 12 and the second sliding frame 13 are provided with a plurality of sliding scrapers 16 on one side close to the filter port 5. The plurality of scrapers 16 are matched with the filter port 5. The two sides of the bottom of the filter 4 are respectively fixedly connected with an outlet pipe 18 and a water inlet pipe 19.

[0038] As an example, Figures 7 to 9 As shown, the top ends of the two rotating shafts 7 are fixedly connected with fan blades 8, and the first sliding frame 12 and the second sliding frame 13 are respectively provided with a plurality of sliding grooves 14, which are rectangular. Sliding components 15 are slidably connected in the plurality of sliding grooves 14, and a plurality of scrapers 16 are respectively fixedly connected to one side of the sliding component 15. The other ends of the two pull ropes 11 pass through the first sliding frame 12 and the second sliding frame 13 respectively, and are respectively connected to the sliding components 15 on the first sliding frame 12 and the second sliding frame 13. Tension springs 17 are fixedly connected to both sides of the inner wall of the filter 4. The two tension springs 17 are respectively located on one side of the first sliding frame 12 and the second sliding frame 13, and are located in the first sliding frame 12 and the second sliding frame 13. The other ends of the two tension springs 17 are respectively fixedly connected to the corresponding sliding components 15.

[0039] As an example, Figure 9 and Figure 10 As shown, the sliding assembly 15 includes a limit block 151, which is in the shape of an "I" character. The limit block 151 is slidably connected in the slide groove 14, and the slide groove 14 is rectangular and cooperates with the limit block 151. The side of the limit block 151 close to the scraper 16 is fixedly connected to a support block 152, and the side of the support block 152 close to the scraper 16 is provided with a limit groove 153, and the limit groove 153 is rectangular. A slider 154 is slidably connected in the limit groove 153, and the slider 154 is rectangular and cooperates with the limit groove 153. A spring 155 is provided between one side of the slider 154 and one side of the limit groove 153, and one side of the scraper 16 is fixedly connected to the slider 154.

[0040] In this embodiment, air enters the top of the air inlet pipe 2, and the air falls into the filter 4 in the air inlet pipe 2, and the larger impurities in the air are filtered through the filter ports 5 on both sides of the filter 4, avoiding the simultaneous influx of impurities of all sizes into the filter frame 43 (subsequent structure), thereby effectively reducing the risk of blockage caused by the rapid accumulation of impurities. The rotating shaft 7 rotates on the support frame 6, thereby driving the push rod 9 at the bottom to rotate around the rotating shaft 7, driving the fixed seat 10 at the other end of the push rod 9 to rotate. When the two fixed seats 10 rotate, the pull ropes 11 (passing through the first sliding frame 12 and the second sliding frame 13, respectively) connected to them are pulled tight. The tightening force of the pull ropes 11 pulls the sliding assemblies 15 on the first sliding frame 12 and the second sliding frame 13 to move along the predetermined trajectory, driving the scraper 16 on them to move tightly against the surface of the filter ports 5 on both sides of the filter 4. The scraper 16 scrapes the filter ports 5 during movement, removing the impurities attached to the surface. The scraped impurities fall into the dust collection area at the bottom of the filter 4 under the action of gravity. When the fixed seat 10 rotates 180 degrees, it reaches the farthest distance pulled by the pull rope 11, thereby ensuring the filtering efficiency of the filter 4 and avoiding the blockage of the filter 4, which affects the air intake flow of the air inlet pipe 2.

[0041] When the gas turbine body 1 is working, the high-speed rotation of the blades inside the gas turbine body 1 causes the gas in the air inlet pipe 2 to enter the gas turbine body 1, resulting in a negative pressure state in the air inlet pipe 2. At this time, the external gas enters the air inlet pipe 2 from the top of the air inlet pipe 2, maintaining the normal operation of the gas turbine body 1. The gas entering the air inlet pipe 2 simultaneously drives the fan blade 8 to rotate, and the fan blade 8 drives the rotating shaft 7 connected thereto to rotate on the support frame 6, thereby driving the fixed seat 10 through the push rod 9 at the bottom. When the two fixed seats 10 rotate in the 0-180 degree range, they pull the two pull ropes 11, which pass through and are connected to the sliding assemblies 15 on the first sliding frame 12 and the second sliding frame 13. After the pull ropes 11 are tightened, they pull the multiple sliding assemblies 15 on the first sliding frame 12 and the second sliding frame 13 to move along their respective sliding grooves 14. The sliding assemblies 15 drive the scraper 16 on them to scrape and clean the filter ports 5 on both sides of the filter 4. When the fixed seat 10 continues to rotate beyond 180 degrees, it no longer pulls the pull ropes 11.

[0042] When the two pull ropes 11 are pulled, the multiple sliding components 15 on the first sliding frame 12 and the second sliding frame 13 are pulled synchronously in opposite directions. The sliding component 15 close to the tension spring 17 pulls the tension spring 17, so that the tension spring 17 generates a reverse force. When the pull rope 11 is not pulled, the pull rope 11 is only subjected to the reaction force of the tension spring 17 itself, thereby driving the sliding component 15 to slide close to the initial position. Through the cooperation of the pull rope 11, the multiple sliding components 15 on the first sliding frame 12 and the second sliding frame 13 are driven to move synchronously, driving the scraper 16 to pass through the filter port 5 again for scraping and resetting. When the rotating shaft 7 continues to rotate after rotating one circle, the above steps are repeated to continuously clean the filter port 5 on the filter 4.

[0043] The spring 155 is compressed and the slider 154 is pushed back to move the filter 5 in the opposite direction.

[0044] It should be noted that, since the driving force inside the gas turbine body 1 is relatively large, the internal driving force is sufficient to drive the blades 8 and the scraper 16 to work normally.

[0045] It should also be noted that when the fixing base 10 rotates, it drives the pull rope 11 without causing the pull rope 11 to be entangled.

[0046] As an example, Figure 6As shown, one side of the air inlet pipe 2 is fixedly connected with a treatment box 20 and a water tank 21, the treatment box 20 and the water tank 21 are provided with a water inlet and a water outlet, the water tank 21 is located above the treatment box 20, the water inlet of the water outlet pipe 18 penetrates through the filter 4 and is fixed to the inner wall bottom of the filter 4, the water outlet of the water outlet pipe 18 penetrates through the air inlet pipe 2 and is connected with the treatment box 20, the treatment box 20 is fixedly connected with a filter plate 22, the filter plate 22 is provided with a filter core, the filter plate 22 is sealed with the inner wall of the treatment box 20 to avoid the unfiltered water from falling, the water outlet of the water inlet pipe 19 penetrates through the filter 4 and is fixedly connected to the inner wall bottom of the filter 4, the water inlet of the water inlet pipe 19 penetrates through the air inlet pipe 2 and is connected with the water tank 21.

[0047] In this embodiment, the scraper 16 cleans the impurities attached to the filter port 5, the impurities fall to the bottom of the filter 4, water is added to the water tank 21, the water in the water tank 21 flows downward due to gravity, according to the principle of the communicating vessel, the water passing through the water inlet pipe 19 is discharged into the filter 4, and flows at the bottom of the filter 4 to wash the impurities cleaned from the bottom of the filter 4, the flowing water carries the impurities to the other side of the bottom of the filter 4, and moves to the position of the water outlet pipe 18, due to the influence of gravity, the water carrying the impurities enters the water outlet pipe 18, passes through the water outlet pipe 18 and enters the treatment box 20, and the water carrying the impurities falls on the filter plate 22, the filter plate 22 processes the water flow, and the processed water flow falls to the bottom of the treatment box 20.

[0048] It should be noted that the filter plate 22 can be coarse filtration, fine filtration, precision filtration, membrane filtration or multi-layer combination filtration, and the filter plate 22 and the water inside are replaced periodically.

[0049] It should be noted that the water outlet pipe 18 and the water inlet pipe 19 are provided with corresponding valves, which are not shown in the figure.

[0050] As an embodiment, as shown in Figure 4 、 Figure 6 and Figure 7 , one side of the treatment box 20 is fixedly connected with a communicating pipe 23, one end of the communicating pipe 23 is located below the filter plate 22 in the treatment box 20, the other end of the communicating pipe 23 is fixedly connected to the top of the water tank 21, one side of the inner wall of the filter 4 is fixedly connected with a conical air inlet cylinder 24, the air inlet cylinder 24 is inclinedly arranged, the bottom of the air inlet cylinder 24 is fixedly connected with a gas conveying pipe 25, the other end of the gas conveying pipe 25 penetrates through the air inlet pipe 2 and the treatment box 20 and is fixedly connected in the communicating pipe 23, one end of the gas conveying pipe 25 located in the communicating pipe 23 is fixedly connected with a one-way valve 44, the water level in the treatment box 20 is higher than the height of the one-way valve 44 at one end of the gas conveying pipe 25.

[0051] In this embodiment, when the water in the treatment box 20 gradually accumulates, the water in the treatment box 20 gradually flows into the connecting pipe 23. The water level in the treatment box 20 is the same as the water level in the connecting pipe 23. Since the air intake pipe 2 is in a negative pressure state, air will continue to enter the air intake pipe 2 from the top of the air intake pipe 2. Part of the air flowing downward will enter the air intake cylinder 24. The air entering is pressurized by the conical air intake cylinder 24. The gas enters the connecting pipe 23 through the air supply pipe 25 at the bottom of the air intake cylinder 24 and is released at the one-way valve 44 at one end of the air supply pipe 25. The gas entering the connecting pipe 23 is first It contacts and mixes with the water in the connecting pipe 23 to form a foamy low-density gas-liquid mixture, causing the internal pressure of the connecting pipe 23 to be lower than the external pressure. The pressure difference drives the water in the treatment box 20 to continuously enter the connecting pipe 23 through the bottom of the connecting pipe 23. The liquid entering the connecting pipe 23 is further mixed with the rising bubbles. The bubbles expand and rise under the action of buoyancy, pushing the fluid above to move upward along the connecting pipe 23 like a piston, and finally sprayed out from the top of the connecting pipe 23 into the water tank 21. The pressure difference at the bottom causes the water in the treatment box 20 to continuously enter the connecting pipe 23, thereby realizing the recycling and reuse of the cleaning water.

[0052] As an example, Figure 2 、 Figure 3 and Figure 11 As shown, a mounting opening 26 is provided on one side of the air intake duct 2. The mounting opening 26 is rectangular. Both sides of the mounting opening 26 are fixedly connected to limit frames 28. Slide rods 27 are slidably connected in the two limit frames 28. One end of the two slide rods 27 is fixedly connected to a baffle 29. The baffle 29 cooperates with the mounting opening 26. A cover plate 30 is fixedly connected to the side of the baffle 29 away from the slide rod 27. A sign 36 is fixedly connected to the cover plate 30. A seal in the shape of a "mouth" is fixedly connected to the side of the cover plate 30 close to the air intake duct 2. A sealing gasket 31 and a "mouth"-shaped sealing groove 32 are provided on one side of the air intake pipe 2. The sealing gasket 31 cooperates with the sealing groove 32. Two fixing frames 33 are fixedly connected to the top of the cover plate 30. A first magnetic block 34 is fixedly connected to the two fixing frames 33. Two second magnetic blocks 35 are fixedly connected to one side of the air intake pipe 2. Both the first magnetic block 34 and the second magnetic block 35 are circular. The two second magnetic blocks 35 are both located above the sealing groove 32. The two first magnetic blocks 34 cooperate with the two second magnetic blocks 35 respectively.

[0053] In this embodiment, the staff pushes the baffle 29, which drives the two sliding bars 27 on both sides to slide in the two limit frames 28 respectively, thereby limiting the movement direction of the baffle 29 so that the baffle 29 can smoothly enter the installation opening 26. After the baffle 29 enters the installation opening 26, the cover plate 30 is fitted against one side of the intake pipe 2, and the sealing gasket 31 on one side of the cover plate 30 enters the sealing groove 32. The contact surfaces of the sealing gasket 31 and the sealing groove 32 are both semicircular, so that the sealing gasket 31 is completely fitted with the sealing groove 32, so that the installation opening 26 is in a sealed state, preventing outside air from entering the intake pipe 2 through the installation opening 26 when the gas turbine body 1 is working. When the cover plate 30 contacts one side of the intake pipe 2, the first magnetic block 34 is adsorbed on the second magnetic block 35 to limit the cover plate 30, preventing the baffle 29 from sliding out of the installation opening 26 during use.

[0054] As an example, Figure 11 and Figure 12 As shown, a plurality of fixed blocks 37 are fixedly connected to the other side of the baffle 29, and a filter frame 43 is provided on each of the plurality of fixed blocks 37. The filter frame 43 is rectangular, and a mounting groove 38 is provided on each of the plurality of fixed blocks 37. An adjustment groove 39 is provided on one side of the mounting groove 38. A fixed frame 40 is sleeved on the fixed block 37, and an insertion block 41 is fixedly connected to the fixed frame 40. The insertion block 41 cooperates with the mounting groove 38, and anti-slip pads 42 are fixedly connected on both sides of the fixed frame 40.

[0055] In this embodiment, corresponding plug holes are provided on the filter frame 43. The filter frame 43 is inserted into the fixing block 37, and then the fixing frame 40 is sleeved on the fixing block 37. When the fixing frame 40 is sleeved on the fixing block 37, the insertion block 41 on the fixing frame 40 moves in the adjustment slot 39, and one side of the fixing frame 40 contacts the filter frame 43, cooperating with the fixing block 37 to clamp the filter frame 43. The insertion block 41 on the fixing frame 40 moves to the top of the installation slot 38, and then the fixing frame 40 is pushed downward to lower the fixing frame 40. The insertion block 41 on the fixing frame 40 enters the installation slot 38, thereby achieving the effect of fixing the installed filter frame 43 and facilitating disassembly. When replacing the filter frame 43, the filter 4 above the intake pipe 2 blocks impurities falling due to gravity. The side opening is provided to pull out the filter frame 43 for replacement, thereby preventing dust generated when replacing the filter frame 43 from entering the gas turbine body 1 through the intake pipe 2.

[0056] It should be noted that the filter 4 in the "V"-shaped space has a storage space of a certain capacity, which can ensure that water flows normally at the bottom of the filter 4 without overflowing. The filter port 5 itself is actually a filter for filtering air. The filter port 5 and the filter frame 43 can ensure that water and water droplets cannot enter the interior of the gas turbine.

[0057] The power of the gas turbine is relatively large, the air inlet cylinder 24 is relatively small and is arranged obliquely, so that the air sucked by the gas turbine can enter the air inlet cylinder 24.

[0058] The air entering the air inlet cylinder 24 enters the communication pipe 23 through the air conveying pipe 25, and the air can be circulated according to the air-lift pump principle without additional power, in cooperation with the one-way valve 44.

[0059] The working principle of the present application is as follows:

[0060] In use, the gas turbine body 1 works to suck the gas in the air inlet pipe 2, so that a negative pressure is formed in the air inlet pipe 2, and the external air enters from the top of the air inlet pipe 2 under the action of the negative pressure, is firstly filtered by the filter 4, and then is filtered again by the filter frame 43, so that the gas entering the gas turbine body 1 is highly clean.

[0061] The air entering the air inlet pipe 2 simultaneously drives the fan blade 8 located in the air inlet pipe 2 to rotate, the fan blade 8 drives the rotating shaft 7 to rotate on the support frame 6, the push rod 9 at the bottom of the rotating shaft 7 rotates and drives the fixed seat 10 to rotate, when the fixed seat 10 rotates to the direction of pulling the pull rope 11 (0-180 degree interval), the pull rope 11 is pulled, the sliding assembly 15 is moved, and the scraper 16 is driven to abut against the filter port 5 of the filter 4 for scraping and cleaning.

[0062] When the fixed seat 10 rotates more than 180 degrees (180-360 degree interval), the pull rope 11 is not pulled any more, at this time, the tension spring 17 on one side of the sliding assembly 15 releases the elastic restoring force stored therein, and pulls the sliding assembly 15 (and the scraper 16) to reset, in the resetting process, the scraper 16 performs reverse scraping and cleaning on the filter port 5, and the fixed seat 10 completes a complete scraping and resetting cycle every rotation.

[0063] The impurities scraped by the scraper 16 fall into the bottom of the filter 4, the water tank 21 injects water into the bottom of the filter 4 through the water inlet pipe 19 for flushing, the flushing water flow carries the impurities to flow in the bottom of the filter 4, and finally flows into the water outlet pipe 18, the water flow containing the impurities is discharged into the treatment tank 20 through the water outlet pipe 18, and the water flow passes through the filter plate 22 in the treatment tank 20 to separate the impurities, so that purified water is obtained.

[0064] At the same time, part of the air flow entering the conical air inlet cylinder 24 is pressurized and sprayed into the communication pipe 23 from the air conveying pipe 25, and is combined with the water in the communication pipe 23 to form a gas-liquid mixture, so that the purified water in the treatment tank 20 is sucked and conveyed back to the water tank 21 through the communication pipe 23, and the flushing water is recycled.

[0065] When the filter frame 43 is replaced, the operator pulls the baffle 29 to remove the filter frame 43 from the air inlet pipe 2, and then the fixed frame 40 can be removed from the fixed block 37, and the filter frame 43 can be removed and replaced.

[0068] 2. The present application is provided with the water outlet pipe 18, the water inlet pipe 19, the treatment box 20 and the water tank 21, and the accumulated impurities at the bottom of the filter 4 are cleaned to avoid the secondary blockage caused by the accumulation of impurities at the bottom of the filter 4, and the filter plate 22, the communication pipe 23, the air inlet cylinder 24 and the gas conveying pipe 25 are used to drive the treated water in the bottom treatment box 20 into the water tank 21, thereby facilitating the reuse of the filter water.
