Description

Technical Field

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

[0002] As one of the core subsystems of a gas turbine, the core function of the gas turbine intake system is to efficiently inhale and pre-treat air, ensure stable delivery to the combustion chamber for fuel mixing and combustion processes, and maintain the efficient operation of the gas turbine based on the Brayton cycle.

[0003] Traditional intake systems usually adopt a fixed intake vane design. Although the structure is simple, significant technical bottlenecks are faced in actual operation: When the gas turbine adapts to different loads or operating conditions, periodic pressure fluctuations are easily induced due to dynamic instability of the air flow inside the compressor, which in turn triggers a surge phenomenon. Surge not only causes a sharp drop in the efficiency of the compressor and a sharp increase in the mechanical stress of components, but may even lead to equipment shutdown in severe cases, greatly limiting the working range and reliability of the gas turbine; In addition, the traditional intake system lacks effective recovery and utilization of combustion waste heat, resulting in significant thermal efficiency losses. At the same time, the fixed vane design is difficult to dynamically match the differentiated requirements of the combustion chamber for air flow rate, flow rate, and pressure. Especially in transient operating conditions, problems such as uneven air flow distribution and increased eddy current losses are easily generated, further restricting the combustion efficiency and turbine output performance; Therefore, there is an urgent need to develop a gas turbine intake system with adjustable flow rate, which can achieve precise control of the vane spacing through innovative structural design to dynamically optimize the intake parameters, suppress the risk of surge, and integrate a waste heat recovery mechanism to improve the comprehensive energy efficiency of the system.

A deflector 5 is arranged on the inner wall of the intake inner cylinder 18. An intake hood 12 is arranged at one end of the heat exchange housing 11 and the intake inner cylinder 18. A mounting seat 13 is installed inside the intake hood 12. An intake main shaft 16 is rotatably installed inside the mounting seat 13. The intake hood 12 and the mounting seat 13 are fixed to each other through a cross-shaped frame. The intake main shaft 16 is rotatably installed in the mounting seat 13 through a bearing seat, which does not affect ventilation during installation and has stable installation. The intake blades 17 are installed on the outer side of the intake main shaft 16 through a dynamic adjustment mechanism 3. When the intake main shaft 16 rotates, it drives the intake blades 17 to rotate to compress and pressurize the air; The dynamic adjustment mechanism 3 includes an adjustment screw 31 rotatably installed in the intake main shaft 16 and an adjustment chute 33 formed 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. The inner side of the intake vane 17 is fixedly installed with an adjustment nut 32 by bolts. The adjustment nut 32 is installed on the adjustment screw 31 through a threaded hole. One end of the adjustment screw 31 is fixedly installed with a transmission worm gear 36. One side of the transmission worm gear 36 is engaged with a transmission worm 35. The self-locking function of the transmission worm gear 36 and the transmission worm 35 ensures the stable rotation of the intake vane 17 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 helical gear 34. The transmission helical gear 34 drives the transmission worm 35 to rotate. The transmission worm 35 drives the transmission worm gear 36 and the adjustment screw 31 to rotate. The inner wall of the mounting seat 13 is fixedly installed with an adjustment pressure cylinder 4, and the position of the adjustment pressure cylinder 4 corresponds to the position of the transmission helical gear 34. There are adjustment pressure cylinders 4 on both sides of the transmission helical gear 34. During adjustment, the two adjustment pressure cylinders 4 are engaged with the transmission helical gear 34 to rotate in different directions, so as to drive the intake vane 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 vane 17 is connected to the intake main shaft 16 through two groups of dynamic adjustment mechanisms 3, which is convenient for stably adjusting the intake vane 17 during use. The adjustment pressure cylinder 4 and the transmission helical gear 34 are respectively arranged in a spiral shape on the inner wall of the mounting seat 13 and the surface of the intake main shaft 16, which is convenient for adjusting multiple intake vanes 17 during use, and the spiral arrangement is convenient for the adjustment pressure cylinder 4 and the transmission helical gear 34 to cooperate with each other to avoid the phenomenon of mutual intersection and collision; a transmission sprocket 37 is fixedly installed on the outer side of the adjustment screw 31, and a transmission chain 38 is sleeved on the outer side of the transmission sprocket 37. A communication hole is provided in the intake main shaft 16 corresponding to the position of the transmission chain 38, and the transmission chain 38 is slidably installed in the communication hole. Through the transmission of the transmission chain 38 and the transmission sprocket 37, the synchronous rotation of the two adjustment screws 31 is ensured, so as to conveniently and stably drive the intake vane 17 to move and adjust the position; The adjusting cylinder 4 includes a fixed seat 41 fixed to the inner wall of the mounting seat 13 and an adjusting slide seat 43 slidably mounted at one end of the fixed seat 41. An adjusting cylinder 42 is fixedly installed inside the fixed seat 41, and a piston rod at one end of the adjusting cylinder 42 is fixedly installed at one end of the adjusting slide seat 43. When installed and used, the adjusting slide seat 43 adjusts and moves more stably. One end of the adjusting slide seat 43 is fixedly installed with an adjusting toothed plate 44, and the adjusting toothed plate 44 meshes with the driving bevel gear 34 through teeth. By driving the adjusting slide seat 43 to descend through the adjusting cylinder 42, the adjusting toothed plate 44 on the adjusting slide seat 43 meshes with the driving bevel gear 34, and the rotation of the intake main shaft 16 drives the driving bevel gear 34 to rotate through the adjusting toothed plate 44; an installation slot 45 is opened at the lower end of the adjusting slide seat 43, and the adjusting toothed plate 44 is fixed to the adjusting slide seat 43 through bolts and the installation slot 45. The clamping and positioning of the installation slot 45 ensure that the adjusting toothed plate 44 is more stable when installed and used. Limiting slide plates 46 are arranged at both ends of the adjusting slide seat 43, and the limiting slide plates 46 are slidably mounted outside the fixed seat 41. The guiding and positioning of the limiting slide plates 46 ensure that the adjusting slide seat 43 is more stable when sliding; the lower end of the adjusting toothed plate 44 is set as an inclined tooth, and the inclined tooth meshes with the teeth of the driving bevel gear 34, which is convenient for the adjusting toothed plate 44 to mesh with the driving bevel gear 34 more stably during use.

[0021] As can be seen from the above description, the present invention has the following beneficial effects: When the intake main shaft 16 rotates, the lower end of the adjusting cylinder 4 descends and engages with the driving bevel gear 34 to drive the driving worm 35 to rotate. The cooperation of the driving worm 35 and the driving worm gear 36 drives the adjusting screw 31 to rotate, so that the adjusting screw 31 drives the adjusting nut 32 and the intake vane 17 to move and position for fine adjustment, thereby adjusting the distance between the intake vanes 17. By adjusting the distance between the wind impellers, the air flow rate, flow and pressure entering the combustion chamber can be controlled, thereby avoiding the occurrence of surging; and appropriate distance adjustment can optimize the overall performance of the gas turbine, change the air flow and pressure entering the combustion chamber, thereby affecting the combustion efficiency and the work capacity of the turbine.

[0022] Embodiment 2: Please refer to Figures 1 to 8 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: The waste heat utilization mechanism 2 includes a heat exchange seat 21 fixed to the outer surface of the intake inner cylinder 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 waste heat while not affecting the combustion of the burner 15. A heat exchange pipe 22 is installed inside the heat exchange seat 21, and the end of the heat exchange pipe 22 is communicated with the heat exchange ring 24 through a heat exchange pump 23. By operating the heat exchange pump 23, the medium flows to the heat exchange pipe 22, and the heat exchange pipe 22 and the heat exchange seat 21 conduct heat to the guide vane 5.

[0023] For the waste heat utilization mechanism 2 and the flow guiding vane 5 adopting the above technical solutions, during use, a certain amount of heat generated by the combustion of the burner 15 is recovered through the heat exchange ring 24, and then guided to the flow guiding vane 5 through the heat exchange pipeline 22 and the heat exchange seat 21. The flow guiding vane 5 preheats the passing air flow, so as to ensure that the air flow burns more fully when entering the combustion seat 14 through the burner 15, and reduce consumption and heat loss.

[0024] Further, refer to Figures 1 to 8 , the flow guiding vane 5 includes a main vane 51 and flow guiding protrusions 52 installed on the surface of the main vane 51. The flow guiding protrusions 52 are in a wavy structure, and their height gradually changes along the air flow direction to optimize the air flow distribution and reduce the eddy current loss. The air can be better guided through the flow guiding protrusions 52, and the angle between the main vane 51 and the adjacent intake blades 17 is the same. The main vane 51 is fixed on the inner wall of the intake inner cylinder 18, which ensures more stable installation and use of the main vane 51 during use. The upper end of the main vane 51 passes through the intake inner cylinder 18 and is connected to the heat exchange seat 21; the main vane 51 includes a heat-conducting copper shell 55 and a support block 54 installed inside the heat-conducting copper shell 55. The support of the support block 54 ensures more stable use of the heat-conducting copper shell 55. Graphene composite heat-conducting nets 53 are installed inside both the heat exchange seat 21 and the heat-conducting copper shell 55, and the gaps of the graphene composite heat-conducting nets 53 are filled with heat-conducting media. After the main vane 51 absorbs heat through the heat-conducting copper shell 55, the graphene composite heat-conducting nets 53 and the filled media, it heats the passing air.

[0025] For the flow guiding vane 5 adopting the above technical solutions, during use, the air flow is guided through the cooperation of the flow guiding vane 5 and the intake blades 17 to ensure uniform distribution of the air flow during flow, avoid too strong or too weak local air flow, thereby improving the combustion efficiency. At the same time, the fine adjustment of the position of the intake blades 17 can reduce the eddy current loss of the air flow and reduce the energy consumption. Working principle and usage process of the present invention: When in use, air is introduced into the inner air intake cylinder 18 between the air intake hood 12 and the mounting base 13. When the air intake main shaft 16 rotates, it drives the air intake blades 17 to rotate to compress air. And when in use, according to the load size connected to the air intake main shaft 16, the adjusting cylinder 42 drives the adjusting slide 43 to descend, so that the adjusting toothed plate 44 on the adjusting slide 43 meshes with the driving bevel gear 34. The rotation of the air intake main shaft 16 drives the adjusting toothed plate 44 to drive the driving bevel gear 34 to rotate, the driving bevel gear 34 drives the driving worm 35 to rotate, the driving worm 35 drives the driving worm gear 36 and the adjusting screw 31 to rotate, and the adjusting screw 31 drives the adjusting nut 32 to slide in the adjusting chute 33 through the thread, thereby driving the air intake blades 17 to slide outside the air intake main shaft 16 for fine adjustment. When reversely adjusting the position of the air intake blades 17, the adjusting toothed plate 44 on the other side meshes with the other side of the driving bevel gear 34. And when ventilating, it is guided by the main piece 51 and the guiding protrusion 52, which is convenient for the adjacent air intake blades 17 to compress air more stably. At the same time, the heat exchange ring 24 and the internal medium absorb the preheating of the combustion of the burner 15. The medium flows to the heat exchange pipeline 22 through the operation of the heat exchange pump 23, and is conducted to the guiding piece 5 through the heat exchange pipeline 22 and the heat exchange seat 21. The main piece 51 absorbs heat through the heat-conducting copper shell 55, the graphene composite heat-conducting net 53 and the filled medium and then heats the passing air, and can strengthen the air pressure, and can better cooperate with the burner 15 for combustion.
