Description

Technical Field

[0001] This invention belongs to the field of gas turbine technology, specifically relating to a gas turbine intake system with air filtration. Background Technology

[0002] The gas turbine intake system is a core auxiliary subsystem at the front end of the gas turbine. It is defined as a complete set of equipment and pipelines that draws in air from the atmospheric environment, pre-treats it through purification, rectification, and noise reduction, and then delivers it to the compressor inlet in a stable and uniform flow pattern and parameters. It is a crucial link in ensuring the efficient, safe, and long-term operation of the Brayton cycle gas turbine. Multi-stage filtration includes coarse and fine filters, with some sections equipped with self-cleaning systems to remove dust, salt spray, and aerosols, preventing compressor blade wear, scaling, and corrosion.

[0003] Existing gas turbine intake systems equipped with air filters, especially those employing multi-stage filtration structures, are prone to dust accumulation at each filter unit, leading to increased intake resistance and decreased intake efficiency. While pulse-jet backflushing is typically used for online dust removal, this method easily triggers secondary dust re-absorption, failing to achieve ideal dust removal results and negatively impacting the stable operation of the intake system. Therefore, a gas turbine intake system with integrated air filtration is needed to address these issues. Summary of the Invention

With the help of the clutch electric lever and reverse gear of the clutch mechanism, the dust removal and ventilation modes can be automatically switched. During dust removal, the ventilation area is reduced by adjusting plate A and adjusting plate B to enhance the purging force. During normal operation, the ventilation port is fully opened to reduce pressure loss. The accumulated dust can be discharged through the cleaning port and cleaning pipe without stopping the machine, thus improving the availability of the equipment.

[0017] 3. The air outlet, intermediate cylinder, and fixed cylinder of the filter cartridge are reinforced by air guide plates, connecting frames, and auxiliary support plates. The guide frame ensures the smooth operation of the cleaning linkage and cleaning baffle. All structures work together to achieve integrated filtration, anti-clogging, air guiding, dust removal, and dust discharge.

[0023] As can be seen from the above description, the present invention has the following beneficial effects: the compressor main shaft drives the transmission shaft 24, which in turn drives the rotating shaft 13 to rotate through the transmission bevel gear 17 and the transmission helical gear 16, so that the cleaning scraper 54 continuously adheres to the filter element 12 to scrape off dust.

[0026] Further reading is available. Figure 1-7 The clutch mechanism 4 includes a transmission frame 44 and a clutch electric lever 41. The clutch electric lever 41 is fixedly installed on the top of the inner side of the main air intake housing 1, and its output end is rotatably engaged with a clutch helical gear 42. The transmission frame 44 is fixed on the surface of the cleaning turntable 35, and a clutch helical gear ring 43 is fixedly installed on its inner side. The clutch helical gear 42 can mesh with the clutch helical gear ring 43 and the transmission helical gear 16. A reverse seat 421 is fixedly installed on the output end of the clutch electric lever 41, and two mutually meshing reverse gears 422 are rotatably engaged on the surface of the reverse seat 421. A reverse bevel gear 423 is fixedly installed on one side of each of the two reverse gears 422, and the two reverse bevel gears 423 mesh with the transmission helical gear 16 and the clutch helical gear ring 43, respectively. The electric clutch enables forward dust cleaning and reverse reset closing, with rapid switching and reliable operation. An adjusting plate A46 is fixedly installed on the inner side of one end of the air outlet 111, and an air vent A45 is provided between the adjusting plates A46; an adjusting plate B48 is fixedly installed on the inner side of the cleaning turntable 35, and an air vent B47 is provided between the adjusting plates B48; the air vent A45, adjusting plate A46, air vent B47, and adjusting plate B48 cooperate with each other; during dust cleaning, the ventilation area is reduced and the blowing airflow is enhanced; during normal operation, the air vents are fully open to ensure smooth air intake and low pressure.

[0027] By adopting the above technical solution, the angle of the air guide fan blade 23 can be flexibly adjusted by adjusting the electric lever 25, the helical gear 28, and the bevel gear 26 to optimize the airflow field and adapt to different operating conditions of the compressor. With the help of the clutch electric lever 41, the reverse gear 422 and other components of the clutch mechanism 4, the automatic switching between dust removal and ventilation modes can be realized. During dust removal, the ventilation area is reduced by adjusting plate A46 and adjusting plate B48 to enhance the purging force. During normal operation, the ventilation port is fully opened to reduce pressure loss. The accumulated dust can be discharged through the cleaning port 32 and the cleaning pipe 31 without stopping the machine, thereby improving the availability of the equipment.

[0028] The working principle and usage process of this invention are as follows: During use, one end of the main pipe 21 is installed at the air inlet end of the gas turbine compressor, and the drive shaft 24 is fixedly connected to the compressor main shaft. During the air intake process, air enters from the fixed cylinder 113 at the lower end of the filter cartridge 11 and is filtered and purified step by step by multiple filter elements 12. At the same time, the compressor main shaft drives the drive shaft 24 to rotate. The drive shaft 24 drives the rotating shaft 13 to rotate through the drive bevel gear 17 and the drive helical gear 16. The rotating shaft 13 drives the cleaning scraper 54 to rotate along the surface of the filter element 12, scraping off the impurities accumulated on the surface in real time to ensure smooth air passage. The scraped impurities are pushed to the outside by the arc-shaped cleaning scraper 54, enter the inner side of the air guide plate 51 through the cleaning gap 55, and then fall into the bottom of the main air intake box 1 through the gap of the connecting frame 52. The cleaning scraper 54 also drives the cleaning brush 53 to clean the connecting frame 52 to avoid impurities from clogging and ensure smooth dust falling. The filtered air enters the main pipe 21, is rectified by the air guide fan blade 23, and then enters the compressor. The angle of the guide vane 23 can be adjusted according to the compressor impeller angle and actual operating conditions. During adjustment, the electric adjustment lever 25 is activated, which pushes the adjustment turntable 29 to move. The adjustment turntable 29 drives the adjustment helical gear 28 to slide along the adjustment hexagonal prism 27, so that the adjustment helical gear 28 meshes with the adjustment bevel gear 26. The transmission shaft 24 drives the adjustment hexagonal prism 27 and the adjustment helical gear 28 to rotate. The adjustment helical gear 28 drives the adjustment bevel gear 26 and the guide vane 23 to deflect, thereby adjusting the intake angle, so that the airflow enters the compressor more smoothly, improving intake efficiency and operating stability. After prolonged operation, the accumulated dust inside the main intake housing 1 needs to be cleaned. The clutch electric lever 41 is activated, pushing the clutch helical gear 42 to move, causing it to mesh simultaneously with the transmission helical gear 16 and the clutch helical gear ring 43. The transmission helical gear 16 drives the clutch helical gear ring 43 and the transmission frame 44 to rotate via the clutch helical gear 42, thereby driving the cleaning turntable 35 to rotate. When the cleaning turntable 35 rotates, the adjusting plate B48 and adjusting plate A46 rotate relative to each other, reducing the airflow area and increasing the internal airflow velocity. Simultaneously, the cleaning turntable 35 drives the cleaning connecting rod 34 and the cleaning baffle 33 to move, opening the cleaning port 32. At this time, the airflow enters the main intake housing 1 through the cleaning gap 55, forcefully blowing the accumulated dust out from the cleaning port 32 and the cleaning pipe 31, achieving online cleaning without dust or backflow. After cleaning, the clutch electric lever 41 drives the reverse seat 421 upward, causing the reverse bevel gear 423 to mesh with the transmission helical gear 16 and the clutch helical gear ring 43 respectively; under the action of the reverse gear 422, the clutch helical gear ring 43 rotates in the opposite direction to the cleaning turntable 35, causing the cleaning baffle 33 to reset and block the cleaning port 32; at the same time, the vent A45 and the vent B47 are fully aligned and connected again, and the system returns to the normal air intake working state, ensuring smooth, efficient and stable air intake.
