Description

Technical Field

[0001] The invention belongs to the technical field of gas turbines, in particular to an air pre-filtering device for a gas turbine. Background Art

[0002] Gas turbines, vacuum pumps, air compressors and other machines need to inhale air when working. Since they are mostly used in industrial production, they are affected by the environment in industrial production, and there will be a large amount of impurities in the air. If the impurities in the air enter the interior of the vacuum pump, they will accumulate on the compression components. Long-term use will cause damage to the machine. Therefore, in the prior art, a filter device is usually used to filter the air.

[0003] Since the air introduced into the gas turbine is used as oxygen supply to ignite the internal fuel, the air entering the gas turbine not only needs to be cleaned but also needs to be dehumidified to ensure that no water vapor enters the gas turbine, thereby avoiding problems such as explosions. The dust removal components that have absorbed water vapor are more likely to absorb dust, which can cause the retained dust and impurities to easily block the filter mesh and other related parts, thereby reducing the filtering effect, so improvements are needed. Summary of the invention

The side of the heat-conducting inner cylinder away from the fixed side cylinder is mutually squeezed with the outer surface of the water-absorbing inner pad through the plug interface, the end of the exhaust pipe away from the U-shaped transfer pipe extends to the outside of the container shell, and the end of the water delivery pipe away from the fixed pump body extends to the outside of the container shell.

[0009] Furthermore, the filtering component includes a water storage inner shell, and water-blocking baffles are symmetrically arranged on the left and right sides of the inner wall of the water storage inner shell. The inner cavity of the water-blocking baffle is fixedly connected to a drainage baffle, and the gas can only be discharged to the outside of the water storage inner shell through the uniform through-holes of the drainage baffle. The drainage baffle is rotatably connected to a docking pipe on the side away from the water-blocking baffle. The docking pipe is provided with a through-hole for docking with the drainage baffle. However, when the docking pipe and the drainage baffle are completely offset, the docking pipe will completely block the drainage baffle. The lower part of the outer surface of the docking pipe is rollingly connected to a control wheel, and the bottom of the control wheel is fixedly connected to an independent motor.

[0010] Furthermore, the upper surface of the water storage inner shell is fixedly connected to the center of the top of the inner wall of the container shell, the lower surface of the water baffle is fixedly connected to the bottom of the inner wall of the water storage inner shell, the outer surface of the water baffle is fixedly connected to the inner wall of the container shell, and the side of the connecting pipe away from the water baffle is rotatably connected to the side of the inner wall of the U-shaped connecting pipe away from the exhaust pipe.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. The device can first pass the air supplied to the turbine into the internal water body, and use the adsorption capacity of water to remove impurities in the air to achieve a filtering effect. The method of use only requires replacing the water body to achieve the effect of replacing the filter element, which is more environmentally friendly. Since the humidity of the air treated in this way will increase, a water-absorbing inner pad is set inside the U-shaped transfer pipe to further remove moisture from the gas, thereby avoiding the problem of excessive water vapor content inside the gas turbine that is prone to explosion.

[0015] 2. After continuous operation, the internal humidity of the water-absorbing inner pad after absorbing water vapor will increase, which will lead to a decrease in its water absorption performance and the water vapor filtering effect of the device will also deteriorate. The manual maintenance method requires frequent opening of the device to replace the water-absorbing inner pad, which is inconvenient to operate. Therefore, dehumidification components are provided on both sides of the water-absorbing inner pad. The heat conduction function of the heat-conducting inner cylinder is used to vaporize the moisture inside the water-absorbing inner pad, and then it is discharged through the threaded vacuum pump, thereby reducing the humidity inside the water-absorbing inner pad and restoring its water absorption performance, so that normal work can continue, which is more convenient and efficient to use.

[0016] 3. When filling the water storage inner shell, in order to prevent the fixed pump body from pumping too much water and causing the water to be directly discharged into the U-shaped transfer pipe through the docking pipe, the docking pipe will rotate under the rolling friction of the rotating control wheel, so that the docking pipe and the drainage baffle are completely offset, and then the water-blocking baffle is completely blocked to prevent the overflowing water from entering the U-shaped transfer pipe, causing the water to directly enter the connected turbine and cause turbine failure.

[0017] 4. After the modification, the rotating inner tube of the device can filter the larger impurities sucked into the water body and confine the impurities to the bottom of the rotating inner tube, preventing the impurities from spreading and causing the water body to be quickly polluted, which requires frequent replacement. When changing water, the rotating inner tube can automatically discharge the accumulated impurities through the open strip grooves, thereby avoiding the problem of residual internal impurities.

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0027] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: an air pre-filtering device for a gas turbine, comprising a processing component 1, a filter component 2 is arranged at the axis center of the top of the inner wall of the processing component 1, and exhaust components 3 are symmetrically arranged on the left and right sides of the outer surface of the filter component 2;

[0028] The exhaust component 3 includes a U-shaped transfer tube 31, the inner wall of which is fixedly connected with a water-absorbing inner pad 32, which is composed of a combination of water-absorbing materials such as sponge and activated carbon, so the structure is relatively soft, and an exhaust pipe 33 is fixedly connected to one end of the U-shaped transfer tube 31 away from the filter component 2, and dehumidification components 5 are symmetrically arranged on the front and rear sides of the outer surface of the water-absorbing inner pad 32;

[0029] The dehumidification component 5 includes a fixed side cylinder 51, the inner cavity of the fixed side cylinder 51 is fixedly connected to a waterproof motor 53, the outer surface of the output shaft of the waterproof motor 53 is fixedly connected to a threaded vacuum cylinder 54, the outer surface of the threaded vacuum cylinder 54 is rotatably connected to a heat-conducting inner cylinder 55, a heating ring 56 is fixedly connected to the inner cavity of the heat-conducting inner cylinder 55 on one side close to the waterproof motor 53, the inner cavity of the heating ring 56 is evenly provided with heating resistor rods 57, the heating ring 56 supplies power to the connected heating resistor rods 57 to make the heating resistor rods 57 generate heat, which is then transmitted to the fitted water-absorbing inner pad 32 through the heat-conducting inner cylinder 55, so that the water-absorbing inner pad 32 is heated and the internal moisture is then vaporized.

[0030] The processing component 1 includes a container shell 11, and fixed plates 17 are symmetrically arranged on the front and rear sides of the outer surface of the container shell 11. A fixed pump body 12 is fixedly connected to the axis of the bottom of the inner wall of the container shell 11, and a switching pipe 13 is symmetrically arranged on the front and rear sides of the inner cavity of the fixed pump body 12. A water delivery pipe 14 is symmetrically arranged on the left and right sides of the inner cavity of the fixed pump body 12. The fixed pump body 12 absorbs water from the outside through the water delivery pipe 14, and then pressurizes the water and transports it to the upper water storage inner shell 21 through the switching pipe 13. The water inside the water storage inner shell 21 can also be reversely extracted and discharged to the outside through the water delivery pipe 14. A torque motor 15 is symmetrically arranged on the upper part of the inner cavity of the container shell 11, and the bottom end of the output shaft of the torque motor 15 is fixedly connected to a friction rotating column 16. The top of the inner cavity of the container shell 11 is evenly provided with a drainage component 4.

[0031] There are six dehumidification components 5, the outer surface of the fixed side cylinder 51 is fixedly connected to the inner wall of the container shell 11, the side of the inner cavity of the fixed side cylinder 51 away from the heat-conducting inner cylinder 55 is evenly provided with exhaust grooves 52, and the outer surface of the heat-conducting inner cylinder 55 is fixedly connected to the inner wall of the fixed side cylinder 51. The side of the heat-conducting inner cylinder 55 away from the fixed side cylinder 51 is pressed against the outer surface of the water-absorbing inner pad 32 through the plug interface, the end of the exhaust pipe 33 away from the U-shaped transfer tube 31 extends to the outside of the container shell 11, and the end of the water delivery pipe 14 away from the fixed pump body 12 extends to the outside of the container shell 11.

[0032] After the device is erected, the exhaust pipes 33 extending from both ends are connected to the turbine that needs oxygen supply, and then the water supply pipes 14 on both sides are connected to the external water supply. Subsequently, the fixed pump body 12 injects water into the water storage inner shell 21 through the water supply pipe 14. When the water is poured from bottom to top through the transfer pipe 13, the water level inside the water storage inner shell 21 will rise. Then, the water injection is stopped when the water level reaches a position below the height of the drainage baffle 23. At this time, the fixed pump body 12 stops working, the water volume inside the water storage inner shell 21 is fixed, and the preparation work is completed.

[0033] When the turbine is working, air is extracted through the exhaust pipe 33. At this time, the external air enters the water storage inner shell 21 through the drainage component 4, and then is discharged from the bottom of the water storage inner shell 21 containing water in the form of bubbles. The gas purified by the water body enters the U-shaped transfer tube 31 through the docking pipe 24, and then the humidity in the gas is reduced when the gas passes through the water-absorbing inner pad 32. Subsequently, the filtered air supplies oxygen to the turbine through the exhaust pipe 33.

[0034] After a period of time, the humidity inside the water-absorbing inner pad 32 will increase, which will lead to a decrease in its water absorption performance. At this time, the turbine is stopped first, the dehumidification component 5 is started, and the heating ring 56 heats up the heat-conducting inner cylinder 55 as a whole through the heating resistor rod 57, and then the water-absorbing inner pad 32 is heated up through the heat conduction effect. At this time, the moisture inside the water-absorbing inner pad 32 will absorb heat and vaporize, and the waterproof motor 53 rotates the threaded vacuum cylinder 54 at high speed to suck the vaporized water vapor out from the inside of the U-shaped transfer tube 31, and discharge it to the inside of the container shell 11 through the exhaust groove 52, thereby reducing the humidity of the water-absorbing inner pad 32 and restoring its water absorption performance. When the dehumidification work is not performed, since the threaded vacuum cylinder 54 does not rotate, the gas passing through the water-absorbing inner pad 32 will be blocked by the threaded vacuum cylinder 54 and cannot pass through the exhaust groove 52, thereby preventing leakage problems.

[0035] When the turbine is performing normal air intake operation, the drainage baffle 23 is normally connected to the air port of the docking pipe 24; when the water storage inner shell 21 is filled with water, in order to prevent the fixed pump body 12 from pumping too much water, causing the water to be directly discharged into the U-shaped transfer pipe 31 through the docking pipe 24, the docking pipe 24 at this time will rotate under the rolling friction of the rotating control wheel 26, so that the docking pipe 24 and the drainage baffle 23 are completely offset, and then the water-isolating baffle 22 is completely blocked to prevent the overflowing water from entering the U-shaped transfer pipe 31.

[0036] Example 2, please refer to Figure 1-Figure 7 The present invention provides a technical solution: on the basis of embodiment one, the filtering component 2 includes a water storage inner shell 21, and water-blocking baffles 22 are symmetrically arranged on the left and right sides of the inner wall of the water storage inner shell 21. The inner cavity of the water-blocking baffle 22 is fixedly connected with a drainage baffle 23, and the gas can only be discharged to the outside of the water storage inner shell 21 through the uniform through-holes of the drainage baffle 23. The drainage baffle 23 is rotatably connected to a docking pipe 24 on the side away from the water-blocking baffle 22. The docking pipe 24 is provided with a through-hole for docking with the drainage baffle 23. However, when the docking pipe 24 is completely staggered with the drainage baffle 23, the docking pipe 24 will completely block the drainage baffle 23. A control wheel 26 is rollingly connected to the lower part of the outer surface of the docking pipe 24, and an independent motor 25 is fixedly connected to the bottom of the control wheel 26.

[0037] The upper surface of the water storage inner shell 21 is fixedly connected to the center of the top of the inner wall of the container shell 11, the lower surface of the water-blocking baffle 22 is fixedly connected to the bottom of the inner wall of the water storage inner shell 21, the outer surface of the water-blocking baffle 22 is fixedly connected to the inner wall of the container shell 11, and the side of the connecting pipe 24 away from the water-blocking baffle 22 is rotatably connected to the side of the inner wall of the U-shaped switching pipe 31 away from the exhaust pipe 33. The top of the switching connecting pipe 13 is fixedly connected to the bottom of the inner cavity of the water storage inner shell 21, and the top of the switching connecting pipe 13 extends to the inside of the water storage inner shell 21, the bottom end of the output shaft of the torque motor 15 extends to the inside of the water storage inner shell 21, and the bottom end of the drainage component 4 and the bottom of the inner wall of the water storage inner shell 21 are pressed against each other.

[0038] The drainage component 4 includes a guide outer shell 41, the inner wall of the guide outer shell 41 is rotatably connected to a rotating inner tube 42, the upper part of the inner wall of the rotating inner tube 42 is fixedly connected to a compression soft sleeve 43, the bottom end of the compression soft sleeve 43 is fixedly connected to a clustering strip shell 44, the clustering strip shell 44 is composed of six vertical plug plates complementary to the strip grooves 45 and a cover shell on the top, and each strip groove 45 is provided with a mesh for filtering larger objects, the bottom of the inner cavity of the rotating inner tube 42 is evenly provided with strip grooves 45, and the bottom end of the rotating inner tube 42 extends to the bottom of the inner wall of the water storage inner shell 21, and is in a relatively low position.

[0039] There are three drainage components 4. The outer surface of the guide shell 41 is fixedly connected to the top of the inner cavity of the container shell 11, the outer surface of the clustering strip shell 44 is slidingly connected to the inner wall of the rotating inner tube 42, and the bottom of the clustering strip shell 44 is plugged into the bottom of the inner cavity of the rotating inner tube 42 through a strip groove 45, and the outer surface of the rotating inner tube 42 is rollingly connected to the outer surface of the friction rotating column 16.

[0040] The air enters the interior of the water storage inner shell 21 through the guide outer shell 41. Since the power of the turbine exhaust is too large, the impact force of the air on the inner wall of the rotating inner tube 42 from top to bottom will be relatively large. At this time, under the impact of the airflow, the clustering strip shell 44 will slide from top to bottom along the strip groove 45, and the compression soft sleeve 43 will be stretched to expand the actual inner diameter of the rotating inner tube 42. After the clustering strip shell 44 is inserted into the strip groove 45, the air entering the drainage component 4 will first pass through the clustering strip shell 44 for simple filtration, and the larger solid impurities will be isolated inside the rotating inner tube 42, and then the water body will filter the finer dust impurities in the air.

[0041] When the turbine inhales air, the torque motor 15 at the top controls the rotating inner tube 42 to continuously rotate centrifugally through the friction rotating column 16. At this time, the impurities at the bottom of the inner wall of the rotating inner tube 42 will rotate continuously under the action of centrifugal force, thereby preventing the impurities from blocking the mesh of the clustering strip shell 44. After working for a period of time, the turbine stops working. At this time, the clustering strip shell 44 will slide upward under the rebound action of the compression soft sleeve 43, thereby opening the strip groove 45 at the bottom of the rotating inner tube 42. However, the rotating inner tube 42 is still rotating centrifugally at this time, so the impurities gathered at the bottom of the rotating inner tube 42 will be discharged into the water body inside the water storage inner shell 21 through the opened strip groove 45, and will be discharged through the water supply pipe 14 when changing water.

[0042] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
