Description

Technical Field

[0001] The present invention belongs to the technical field of gas turbines, and in particular relates to a gas turbine air intake system with adjustable flow rate. Background Art

[0002] As one of the core subsystems of a gas turbine, the gas turbine air intake system's core function is to efficiently inhale and pre-treat air, ensuring stable delivery to the combustion chamber to participate in the fuel mixing and combustion process, thereby maintaining efficient operation of the gas turbine based on the Brayton cycle.

[0003] Traditional air intake systems typically use a fixed intake vane design. Although simple in structure, they face significant technical bottlenecks in actual operation:

[0004] When a gas turbine is adapted to different loads or operating conditions, dynamic instability of the airflow inside the compressor can easily induce periodic pressure fluctuations, leading to surge. Surge not only causes a sharp drop in compressor efficiency and a sharp increase in mechanical stress on components, but in severe cases can even cause equipment shutdown, greatly limiting the operating range and reliability of the gas turbine.

[0005] Furthermore, traditional intake systems lack effective recovery and utilization of combustion waste heat, resulting in significant thermal efficiency losses. Furthermore, fixed blade designs struggle to dynamically adapt to the combustion chamber's varying requirements for air velocity, flow rate, and pressure. This can lead to uneven airflow distribution and increased vortex losses, particularly under transient conditions, further restricting combustion efficiency and turbine output performance.

[0006] Therefore, there is an urgent need to develop a gas turbine intake system with adjustable flow rate, which can achieve precise control of blade spacing through innovative structural design, dynamically optimize intake parameters, suppress surge risks, and integrate waste heat recovery mechanisms to improve the overall energy efficiency of the system.

The inner wall of the cylinder 18 is provided with a guide plate 5, and one end of the heat exchange shell 11 and the air intake inner cylinder 18 is provided with an air intake cover 12. A mounting seat 13 is installed on the inner side of the air intake cover 12, and an air intake main shaft 16 is rotatably installed on the inner side of the mounting seat 13.

The installation does not affect the ventilation and is stable. The outer side of the air intake main shaft 16 is installed with an air intake blade 17 through a dynamic adjustment mechanism 3. When the air intake main shaft 16 rotates, it drives the air intake blade 17 to rotate to compress and pressurize the air.

[0042] The dynamic adjustment mechanism 3 includes an adjustment screw 31 rotatably mounted in the intake main shaft 16 and an adjustment slot 33 provided on the surface of the intake main shaft 16. The adjustment stroke of the dynamic adjustment mechanism 3 is controlled by the displacement of the piston rod of the adjustment cylinder, and the adjustment cylinder is a servo hydraulic cylinder. An adjustment nut 32 is fixedly mounted on the inner side of the intake blade 17 by bolts. The adjustment nut 32 is mounted on the adjustment screw 31 through a threaded hole. A transmission worm gear 36 is fixedly mounted on one end of the adjustment screw 31. A transmission worm 35 is meshed with one side of the transmission worm gear 36. The transmission worm gear 36 and The self-locking effect of the transmission worm 35 ensures that the intake blades 17 rotate stably when not adjusted. The transmission worm 35 is rotatably installed in the intake main shaft 16, and one end of the transmission worm 35 passes through the intake main shaft 16 and is fixedly installed with a transmission bevel gear 34. The transmission bevel gear 34 drives the transmission worm 35 to rotate, and the transmission worm 35 drives the transmission worm wheel 36 and the adjusting screw 31 to rotate. The inner wall of the mounting seat 13 is fixedly installed with an adjusting pressure cylinder 4, and the position of the adjusting pressure cylinder 4 corresponds to the position of the transmission bevel gear 34. Adjustment holes are provided on both sides of the transmission bevel gear 34. The pressure cylinder 4 is engaged with the transmission bevel gear 34 to rotate in different directions during adjustment, thereby driving the intake blades 17 to move forward and backward for fine adjustment; the dynamic adjustment mechanism 3 is symmetrically installed on the intake main shaft 16, and the intake blades 17 are connected to the intake main shaft 16 through two sets of dynamic adjustment mechanisms 3, which makes it convenient to stably adjust the intake blades 17 during use. The adjustment pressure cylinder 4 and the transmission bevel gear 34 are respectively arranged in a spiral shape on the inner wall of the mounting base 13 and the surface of the intake main shaft 16, which makes it convenient to adjust multiple intake blades 17 during use. , and the spiral arrangement facilitates the mutual cooperation between the adjustment cylinder 4 and the transmission bevel gear 34 to avoid the phenomenon of mutual intersection and collision; a transmission sprocket 37 is fixedly installed on the outside of the adjustment screw 31, and a transmission gear chain 38 is sleeved on the outside of the transmission sprocket 37.

The transmission of the transmission gear chain 38 and the transmission sprocket 37 ensures that the two adjustment screws 31 rotate synchronously, thereby conveniently and stably driving the intake blades 17 to move and adjust the position;

[0043] The regulating pressure cylinder 4 includes a fixed seat 41 fixed to the inner wall of the mounting seat 13 and an regulating slide 43 slidably mounted on one end of the fixed seat 41. An regulating cylinder 42 is fixedly mounted inside the fixed seat 41. The piston rod at one end of the regulating cylinder 42 is fixedly mounted on one end of the regulating slide 43. When installed and used, the regulating slide 43 is adjusted and moved more stably. An regulating tooth plate 44 is fixedly mounted on one end of the regulating slide 43, and the regulating tooth plate 44 is engaged with the transmission bevel gear 34 through teeth. The regulating slide 43 is driven down by the regulating cylinder 42, so that the regulating tooth plate 44 on the regulating slide 43 is engaged with the transmission bevel gear 34. The tooth plate 44 is adjusted by the rotation of the intake main shaft 16. The transmission bevel gear 34 is driven to rotate; the lower end of the adjusting slide 43 is provided with a mounting slot 45, and the adjusting tooth plate 44 is fixed to the adjusting slide 43 by bolts and the mounting slot 45. The engagement and positioning of the mounting slot 45 ensure that the adjusting tooth plate 44 is installed and used more stably. Limiting slides 46 are provided at both ends of the adjusting slide 43, and the limiting slides 46 are slidably installed on the outside of the fixed seat 41. The guiding positioning of the limiting slide 46 ensures that the adjusting slide 43 is more stable when sliding; the lower end of the adjusting tooth plate 44 is set to be helical teeth, and the helical teeth are engaged with the teeth of the transmission bevel gear 34, which makes it convenient to adjust the tooth plate 44 and the transmission bevel gear 34 to engage more stably when in use.

[0044] From the above description, it can be seen that the present invention has the following beneficial effects: when the intake main shaft 16 rotates, the lower end of the adjustment pressure cylinder 4 is lowered and engaged on the transmission bevel gear 34 to drive the transmission worm 35 to rotate, and the transmission worm 35 and the transmission worm wheel 36 drive the adjusting screw 31 to rotate, so that the adjusting screw 31 drives the adjusting nut 32 and the intake blade 17 to move and fine-tune the position, thereby adjusting the distance between the intake blades 17. By adjusting the pitch of the impellers, the air flow rate and pressure entering the combustion chamber can be controlled, thereby avoiding the occurrence of surge; and appropriate pitch adjustment can optimize the overall performance of the gas turbine, and can change the air flow rate and pressure entering the combustion chamber, thereby affecting the combustion efficiency and the working capacity of the turbine.

[0045] Example 2: Please refer to Figures 1 to 8 As shown, based on the first embodiment, the present invention provides a technical solution: the waste heat utilization mechanism 2 includes a heat exchange seat 21 fixed on the outer surface of the air intake inner tube 18 and a heat exchange ring 24 installed in the combustion seat 14. The heat exchange ring 24 is installed on the inner wall of the combustion seat 14 to absorb the waste heat without affecting the combustion of the burner 15. A heat exchange pipe 22 is installed on the inner side of the heat exchange seat 21. The end of the heat exchange pipe 22 is connected to the heat exchange ring 24 through a heat exchange pump 23. The operation of the heat exchange pump 23 causes the medium to flow to the heat exchange pipe 22, and conducts heat to the guide plate 5 through the heat exchange pipe 22 and the heat exchange seat 21.

[0046] The waste heat utilization mechanism 2 and the guide plate 5 of the above-mentioned technical solution recover a certain amount of heat generated by the combustion of the burner 15 through the heat exchange ring 24 during use, and then guide the heat to the guide plate 5 through the heat exchange pipe 22 and the heat exchange seat 21, and preheat the passing airflow through the guide plate 5, thereby ensuring that the airflow enters the combustion seat 14 and burns more fully through the burner 15, and reducing consumption and heat loss.

[0047] Further, see Figures 1 to 8 The guide piece 5 includes a main piece 51 and a guide protrusion 52 installed on the surface of the main piece 51. The guide protrusion 52 is a wave-shaped structure, and its height gradually changes along the airflow direction to optimize the airflow distribution and reduce vortex loss. The guide protrusion 52 can better guide the air, and the main piece 51 has the same angle as the adjacent intake blade 17. The main piece 51 is fixed to the inner wall of the intake inner tube 18, which ensures that the main piece 51 is more stable when installed and used, and the upper end of the main piece 51 passes through the intake inner tube 18. It is connected to the heat exchange seat 21; the main piece 51 includes a heat-conducting copper shell 55 and a support block 54 installed inside the heat-conducting copper shell 55. The reinforced support of the support block 54 ensures that the heat-conducting copper shell 55 is more stable during use. The heat exchange seat 21 and the heat-conducting copper shell 55 are both installed with a graphene composite heat-conducting mesh 53, and the gaps in the graphene composite heat-conducting mesh 53 are filled with a heat-conducting medium. The main piece 51 absorbs heat through the heat-conducting copper shell 55, the graphene composite heat-conducting mesh 53 and the filled medium and heats the passing air.

[0048] The guide vane 5 of the above technical solution guides the airflow in use by cooperating with the guide vane 5 and the air intake blade 17 to ensure uniform distribution of the airflow, avoid excessive or weak local airflow, thereby improving combustion efficiency. At the same time, fine-tuning the position of the air intake blade 17 can reduce the vortex loss of the airflow and reduce energy consumption.

[0049] The working principle and use process of the present invention are as follows: when in use, air is ventilated into the air intake inner cylinder 18 through the space between the air intake cover 12 and the mounting seat 13, and the air intake main shaft 16 drives the air intake blades 17 to rotate to compress the air. When in use, according to the load size connected to the air intake main shaft 16, the adjustment slide 43 is driven down by the adjustment cylinder 42, so that the adjustment tooth plate 44 on the adjustment slide 43 is engaged with the transmission bevel gear 34. The rotation of the air intake main shaft 16 drives the adjustment tooth plate 44 to rotate the transmission bevel gear 34, and the transmission bevel gear 34 drives the transmission worm 35 to rotate. The transmission worm 35 drives the transmission worm wheel 36 and the adjusting screw 31 to rotate. The adjusting screw 31 drives the adjusting nut 32 to slide in the adjusting slot 33 through the thread, thereby driving the air intake. The blades 17 slide on the outside of the intake main shaft 16 for fine adjustment. When adjusting the position of the intake blades 17 in the reverse direction, the adjusting tooth plate 44 on the other side can be engaged with the other side of the transmission bevel gear 34. During ventilation, the main plate 51 and the guide protrusion 52 are used for guidance, which makes it convenient for the adjacent intake blades 17 to compress the air more stably. At the same time, the heat exchange ring 24 and the internal medium absorb the preheating of the burner 15 combustion. The heat exchange pump 23 is operated to make the medium flow to the heat exchange pipe 22, and heat is conducted to the guide plate 5 through the heat exchange pipe 22 and the heat exchange seat 21. The main plate 51 absorbs heat through the heat-conducting copper shell 55, the graphene composite heat-conducting net 53 and the filled medium, and heats the passing air, and can increase the air pressure, which can better cooperate with the burner 15 for combustion.
