Description

Technical Field

[0001] The present invention belongs to the technical field of gas turbines, and particularly relates to a self-cleaning filter for a gas turbine. Background Art

[0002] As a core component of the intake system, the gas turbine filter is used to efficiently filter out particulate matter and impurities in the air, ensure the cleanliness of the internal flow path of the gas turbine, and thereby reduce the wear and corrosion risks of key components (such as compressor blades, combustion chambers, etc.), extend the service life of the equipment, and reduce unplanned shutdowns and maintenance costs.

[0003] However, the existing filters face the following technical bottlenecks during long-term operation: Contradiction between impurity adsorption and cleaning efficiency: Traditional filters mostly adopt back-blowing cleaning technology, which uses reverse air flow to impact the filter screen to peel off impurities. However, during the back-blowing process, air flow dead zones are easily formed, resulting in incomplete cleaning of local areas of the filter screen, and the gradual accumulation of impurities blocks the pores, significantly reducing the ventilation efficiency. At the same time, the back-blowing operation requires suspending the intake air or reducing the load operation, which directly affects the continuity and output power of the gas turbine, causing energy loss and decreased economy; Insufficient mechanical vibration and structural stability: Some improved solutions attempt to introduce mechanical vibration to assist in dust cleaning, but lack effective buffer and damping designs. High-frequency vibration is likely to cause fatigue damage to the filter screen structure, and even lead to loosening or fracture of the support components, instead increasing the maintenance frequency and replacement cost. In addition, the vibration transmitted to the outer casing may cause resonance, threatening the safe operation of the overall equipment; Therefore, it is necessary to design a self-cleaning filter for a gas turbine to solve the above problems.

The inclined surfaces of the sliding seat 64 and the auxiliary slider 65 are cooperated to push the damping slide plates 67 to slide on the side mounting plate 33 to provide sliding friction damping, so as to achieve a better shock absorption and buffering effect.

[0025] For the filter cartridge 3 and the connection buffer mechanism 6 adopting the above technical solution, during use, the double-layer filter mesh plates 32 of the filter cartridge 3 are used for support and filtration, so it is more stable when cooperating with the cleaning mechanism 2, and the filter mesh plate 32 is connected to the top frame 31 and the support column 34 through the connection buffer mechanism 6 to buffer when the filter mesh plate 32 vibrates and is stressed, and the buffer effect is better in cooperation with the support between the filter mesh plates 32 by the rubber columns 36.

[0026] Further, refer to Figures 1 to 11, the support buffer mechanism 4 includes a support chute 45 opened on the inner wall of the main housing 11 and a connecting seat 41 fixed on the auxiliary support plate 35.

One end of the connecting seat 41 is rotatably installed with a rotating rod 42 through a rotating shaft, and one end of the rotating rod 42 is rotatably installed with a support slider 43 through a rotating shaft. One side of the support slider 43 is fixedly installed with a support spring 44 through a screw, and one end of the support spring 44 is fixedly installed at one end of the support chute 45 through a screw. When the filter screen plate 32 vibrates and deforms, it presses on the connecting seat 41, and the rotation of the rotating rod 42 drives the support slider 43 to slide in the support chute 45 and compress the support spring 44 for buffering; the air guiding buffer mechanism 5 includes a fixing plate 52 fixed on the transmission rotating shaft 23 and an air guiding cover 51 slidably installed outside the transmission rotating shaft 23. When gas enters the inside of the filter cylinder 3, it is guided and dispersed through the air guiding cover 51, and the wind is evenly distributed and filtered through the filter screen plate 32. Inside the air guiding cover 51, a guiding positioning column 53 is fixedly installed through a screw, and the guiding positioning column 53 is slidably installed on the fixing plate 52 through a sliding hole, and both ends of the guiding positioning column 53 are fixedly installed with guiding springs 54. One end of the guiding spring 54 presses tightly on the fixing plate 52, and when the air guiding cover 51 is subjected to wind force, it cooperates with the guiding of the guiding positioning column 53 to slide and compress the guiding spring 54 for buffering.

[0027] With the support buffer mechanism 4 and the air guiding buffer mechanism 5 adopting the above technical solutions, during use, the filter cylinder 3 is supported and buffered from the outside through the support buffer mechanism 4. When the filter cylinder 3 is filtering, it is subjected to double vibrations of wind force and the cleaning mechanism 2, and can be supported and compressed by the support spring 44 through the rotating rod 42 and the support slider 43 for buffering, so that the filter cylinder 3 is more stable during use and has a longer service life.

[0028] Working principle and usage process of the present invention: During use, an air inlet pipe 12 is connected to an air inlet fan, and air or other gases enter the inner side of the filter cartridge 3 through the air inlet pipe 12 and the communication base 14, are filtered by the filter mesh plate 32 of the filter cartridge 3, and then are discharged through the air outlet pipe 13 and enter a gas turbine for use. When the gas enters the inner side of the filter cartridge 3, it is guided and dispersed by the air guide cover 51, and slides and compresses the guide spring 54 in cooperation with the guide positioning column 53 for buffering, reducing damage to the air guide cover 51. When the filter mesh plate 32 filters, the driving motor 21 drives the transmission worm 222 to rotate, drives the transmission shaft 23 to rotate through the meshing transmission of the transmission worm wheel 221, and the transmission shaft 23 drives the vibration frame 24 to rotate, so that the vibration protrusion 244 rotates to beat and vibrate the filter mesh plate 32, thereby vibrating off the filtered impurities, reducing the phenomenon of blockage due to adsorption during long-term use, and ensuring the continuous operation of the gas turbine without affecting ventilation during use. When the filter mesh plate 32 is stressed and vibrates, it drives the sliding seat 64 to slide in the installation groove 61 and compress the connecting spring 63 for buffering. At the same time, the sliding seat 64 pushes the auxiliary slider 65 to press on the auxiliary spring 66 to provide damping buffering, and the inclined surfaces of the sliding seat 64 and the auxiliary slider 65 are pushed to make the damping slide plate 67 slide on the side mounting plate 33 to provide sliding friction damping, thereby playing a better shock absorption and buffering role and reducing damage to the filter mesh plate 32. Moreover, on the outer side of the filter mesh plate 32, an auxiliary support plate 35 is installed on the connecting seat 41. When the filter mesh plate 32 vibrates and deforms, it presses on the connecting seat 41, and the rotation of the rotating rod 42 drives the support slider 43 to slide in the support chute 45 and compress the support spring 44 for buffering, thereby further protecting the filter mesh plate 32. The impurities falling from the filter mesh plate 32 fall into the collection box 15 for collection, and the cleaning seal door 16 can be opened regularly to clean the interior.
