Description

Technical Field

[0001] This invention relates to the field of combined cycle generator set technology, and in particular to an intelligent automatic start-stop system for combined cycle generator sets. Background Technology

[0002] A gas turbine combined cycle generator set is a system that uses a gas turbine as the main generator, and generates steam through a waste heat boiler to drive a steam turbine for power generation. It can also utilize waste heat for heating and cooling. During operation, the gas turbine produces a large amount of high-temperature exhaust gas, which is introduced into the waste heat boiler to heat water and generate steam, which in turn drives the steam turbine to generate electricity. This not only provides electricity but also fully utilizes the waste heat emitted by the gas turbine, improving energy efficiency.

[0003] In summary, the existing equipment still has the following technical problems: When the gas-steam combined cycle generator set is working, the internal pressure of the steam is not easy to control when it is transported through the pipeline. If the internal pressure of the pipeline reaches the critical value of the pipeline pressure, it will cause the pipeline to rupture, which will affect the normal operation of the entire generator set.

[0025] The intelligent start-stop device for combined cycle generator sets provided by this invention, through the setting of an emergency control mechanism, when the third pressure sensor, the second pressure sensor and the first pressure sensor simultaneously issue an alarm, the control system sends a signal to the dual-axis synchronous servo motor, the first solenoid valve and the second solenoid valve.

After steam is output from inside the generator steam return pipe and steam return collector pipe, part of the steam is transported from the third branch pipe to the middle of the steam flow chamber. This allows the transmission blades to drive the rotating shaft to rotate, thereby causing the heat dissipation blades to rotate. This dissipates the heat absorbed by the steam on the surface of the heat-conducting copper plate through the condensation pipe, thus achieving the purpose of cooling the steam.

[0027] The automatic start-stop control system for combined cycle generator sets provided by this invention collects pressure information inside the pipeline through a first pressure sensor, a second pressure sensor, and a third pressure sensor after the internal pressure of the device is overloaded.

[0042] As described in the background section, when a gas-fired steam combined cycle generator set is in operation, the internal pressure of the steam is difficult to control when it is transported through the pipeline. If the internal pressure of the pipeline reaches the critical value, the pipeline will rupture, which will affect the normal operation of the entire generator set.

[0043] To address this technical problem, the present invention provides an intelligent automatic start-stop system and method for combined cycle generator sets.

[0044] It is used in the steam power generation control of combined cycle generator sets.

[0045] For details, please refer to Figures 1-8The intelligent automatic start-stop system for combined cycle generator sets of the present invention specifically includes a combined cycle generator set 1, and further includes a pressure control mechanism 2, an emergency control mechanism 3, and a steam condensation mechanism 4; the input end of the combined cycle generator set 1 is connected to the pressure control mechanism 2 for controlling the input pressure of the combined cycle generator set 1, the middle part of the pressure control mechanism 2 is connected to the emergency control mechanism 3 for cutting off the input pressure of the combined cycle generator set 1, and the side of the pressure control mechanism 2 away from the combined cycle generator set 1 is connected to the steam condensation mechanism 4 for condensing the water vapor output by the combined cycle generator set 1;

[0047] The intelligent start-stop device for combined cycle generator sets provided by this invention, by setting up a pressure control mechanism 2, when the internal pressure of the pressure control pipeline 6 increases or is overloaded, the piston 16 moves in the middle of the pressure control pipeline 6, which can control the opening and closing of the second diversion pipe 8 and the steam return collection pipe 24. By opening the steam return collection pipe 24, the internal pressure of the pressure control pipeline 6 can be released quickly, thereby achieving the purpose of depressurizing the internal pressure of the pressure control pipeline 6 and thus avoiding pipeline rupture.

[0048] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0051] The air pressure control mechanism 2 includes a main air intake pipe 5, a pressure control pipe 6, a flow splitter assembly, and an air pressure control assembly; the upper end of the combined cycle generator set 1 is connected to the main air intake pipe 5, and the pressure control pipe 6 is fixedly connected to the surface of the main air intake pipe 5, and the main air intake pipe 5 and the pressure control pipe 6 are connected.

[0052] Specifically, the diversion assembly includes a first diversion pipe 7, a second diversion pipe 8, a first solenoid valve 9, and a first pressure sensor 10; the surface of the pressure control pipe 6 is fixedly connected to the first diversion pipe 7, the end of the first diversion pipe 7 away from the pressure control pipe 6 is fixedly connected to the input end of the combined cycle generator set 1, the surface of the pressure control pipe 6 is fixedly connected to the second diversion pipe 8, the end of the second diversion pipe 8 away from the pressure control pipe 6 is fixedly connected to the surface of the first diversion pipe 7, the middle part of the first diversion pipe 7 is fixedly connected to the first solenoid valve 9, and the middle part of the first diversion pipe 7 is fixedly connected to the first pressure sensor 10.

[0053] Specifically, the pneumatic control assembly includes a guide tube 11, a spring 12, a guide groove 13, a slide rod 14, a telescopic rod 15, and a piston 16. The guide tube 11 is fixedly connected to the middle of the pressure control pipeline 6. The spring 12 is installed in the middle of the guide tube 11. The guide groove 13 is opened on the surface of the guide tube 11. The slide rod 14 is slidably connected to the inner wall of the guide groove 13. The telescopic rod 15 is fixedly connected to the surface of the slide rod 14. The telescopic rod 15 is slidably connected to the inner wall of the guide tube 11. The two ends of the spring 12 are fixedly connected to the inner wall of the guide tube 11 and the slide rod 14, respectively. The end of the slide rod 14 away from the spring 12 is fixedly connected to the piston 16. The piston 16 is slidably connected to the inner wall of the pressure control pipeline 6.

[0054] Specifically, the emergency control mechanism 3 includes a dual-axis synchronous servo motor 17, a transmission rod 18, a transmission gear 19, and a tilting assembly; the surface of the pressure control pipe 6 is fixedly connected to the dual-axis synchronous servo motor 17, the output ends on both sides of the dual-axis synchronous servo motor 17 are connected to the transmission rod 18, and the end of the transmission rod 18 away from the dual-axis synchronous servo motor 17 is fixedly connected to the transmission gear 19.

[0055] Specifically, the flipping assembly includes a rotating rod 20, a driven gear 21, and a flap 22; the rotating rod 20 is rotatably connected to the middle of the main intake pipe 5, one end of the rotating rod 20 extends to the outside of the main intake pipe 5, the driven gear 21 is fixedly connected to the end of the rotating rod 20 that extends to the outside of the main intake pipe 5, the driven gear 21 meshes with the transmission gear 19, and the flap 22 is fixedly connected to the surface of the rotating rod 20, and the flap 22 is located in the middle of the main intake pipe 5.

[0056] Through the above structural design, steam is transported from the main intake pipe 5 to the pressure control pipe 6. After reaching the pressure control pipe 6, the steam is transported to the combined cycle generator set 1 through the first branch pipe 7. After entering the combined cycle generator set 1, the steam can drive the combined cycle generator set 1 to generate electricity. When the internal pressure of the pressure control pipe 6 is too high, the steam pushes the piston 16 to move away from the main intake pipe 5. The movement of the piston 16 causes the telescopic rod 15 to slide on the inner wall of the guide groove 13 through the slide rod 14. At the same time, the slide rod 14 pushes the spring. 12. When the piston 16 moves to the side of the second branch pipe 8 away from the first branch pipe 7, the gas can be simultaneously transported from the middle of the first branch pipe 7 and the second branch pipe 8 into the interior of the combined cycle generator set 1. If the pressure inside the pressure control pipe 6 continues to increase, the piston 16 continues to move into the pressure control pipe 6. When the piston 16 moves to the side of the steam return manifold 24 away from the combined cycle generator set 1, the steam enters the steam return manifold 24 through the pressure control pipe 6, thereby further reducing the pressure on the pipe and the combined cycle generator set 1.

[0057] Example 2:

[0058] The intelligent automatic start-stop system for combined cycle generator sets provided in Example 1 has been further optimized, specifically, as follows: Figures 6-8 As shown, the steam condensing mechanism 4 includes a generator steam return pipe 23, a steam return manifold 24, a condensation chamber 28, a second control component, a condensation component, and a return component; the generator steam return pipe 23 is fixedly connected to the surface of the pressure control pipe 6, the end of the generator steam return pipe 23 away from the pressure control pipe 6 is fixedly connected to the condensation chamber 28, the steam output end of the combined cycle generator set 1 is fixedly connected to the generator steam return pipe 23, and the end of the generator steam return pipe 23 away from the combined cycle generator set 1 is fixedly connected to the surface of the steam return manifold 24.

[0059] Specifically, the second control component includes a second solenoid valve 26 and a second pressure sensor 27; the second solenoid valve 26 is fixedly connected to the middle of the steam return manifold 24, and the second pressure sensor 27 is fixedly connected to the middle of the steam return manifold 24.

[0060] Specifically, the condensing assembly includes a third pressure sensor 29, a heat-conducting copper plate 30, a condenser pipe 31, a fan bracket 32, a support rod 33, a steam flow chamber 34, a cross bracket 35, a rotating shaft 36, heat dissipation blades 37, a rotating ring 38, a transmission blade 39, and a third diverter pipe 40. The third pressure sensor 29 is fixedly connected to the middle of the condensing chamber 28. The heat-conducting copper plate 30 is also fixedly connected to the middle of the condensing chamber 28. The condenser pipe 31 is fixedly connected to the side of the heat-conducting copper plate 30 near the inner wall of the condensing chamber 28. The fan bracket 32 ​​is fixedly connected to the top surface of the heat-conducting copper plate 30. The support rod 33 is fixedly connected to the surface of the fan bracket 32. The steam flow chamber 34 is fixedly connected to the top of the support rod 33. The cross bracket 35 is fixedly connected to the middle of the fan bracket 32. The cross bracket 35 rotates at the middle of the fan bracket 36. A rotating shaft 36 is connected to the upper and lower ends of a cross bracket 35, and the top end of the rotating shaft 36 is rotatably connected to the middle of the steam flow chamber 34. A heat dissipation blade 37 is fixedly connected to the surface of the rotating shaft 36, and a rotating ring 38 is fixedly connected to the top end of the rotating shaft 36. The rotating ring 38 is rotatably connected to the middle of the steam flow chamber 34, and a transmission blade 39 is fixedly connected to the outer wall of the rotating ring 38. The transmission blade 39 is rotatably set in the middle of the steam flow chamber 34. A third branch pipe 40 is fixedly connected to the surface of the steam return manifold 24. The end of the third branch pipe 40 away from the steam return manifold 24 is fixedly connected to the end of the condensation chamber 28 away from the steam return manifold 24. The middle of the third branch pipe 40 is fixedly connected to the input and output ports of the steam flow chamber 34.

[0061] Specifically, the reflux assembly includes a condensate storage tank 41, a water outlet pipe 42, and a booster pump 43. The condensate storage tank 41 is fixedly connected to the bottom surface of the condensate tank 28, the water outlet pipe 42 is fixedly connected to the bottom surface of the condensate storage tank 41, and the booster pump 43 is fixedly connected to the surface of the water outlet pipe 42.

[0062] With the above structural design, when the gas enters the interior of the condensing chamber 28 after passing through the steam return manifold 24, the steam supplied to the combined cycle generator set 1 merges into the middle of the steam return manifold 24 through the generator steam return pipe 23, thus entering the middle of the condensing chamber 28 along with the steam in the middle of the steam return manifold 24. After the gas enters the condensing chamber 28, the condensing pipe 31 inside the condensing chamber 28 can quickly condense the water vapor into condensate. The heat carried by the steam is transferred to the surface of the heat-conducting copper plate 30 through the condensing pipe 31. When the gas passes through the generator steam return pipe 23, some of the steam is transported to the steam flow chamber 34 through the third branch pipe 40. In the middle, after the gas is delivered to the middle of the steam flow chamber 34, the steam drives the transmission blade 39 to rotate. The rotation of the transmission blade 39 drives the rotating ring 38 to rotate. The rotation of the rotating ring 38 drives the rotating shaft 36 to rotate, which in turn causes the heat dissipation blade 37 to rotate. The rotation of the heat dissipation blade 37 generates wind, which can dissipate the heat absorbed by the heat-conducting copper plate 30. Some of the steam enters the middle of the condensation chamber 28 from the output end of the third diversion pipe 40 after passing through the steam flow chamber 34, and then condenses. After the steam condenses, it forms condensate. After the condensate enters the condensate storage chamber 41, the booster pump 43 is turned on and delivers the condensate back to the interior of the heating chamber through the outlet pipe 42.

[0063] Example 3:

[0064] The intelligent automatic start-stop system for combined cycle generator sets provided in Examples 1 and 2 has been further optimized. Specifically, as follows: Figure 9 As shown, it includes a first pressure sensor 10, a second pressure sensor 27 and a third pressure sensor 29, which are used to monitor the pressure inside the pipe. It can convert the pressure of an object into an electrical signal for monitoring, control and feedback.

[0065] The first solenoid valve 9 and the second solenoid valve 26 are used to open and close the pipelines in the device that supply steam to the combined cycle generator set 1 and supply steam.

[0066] A sound and light alarm module is used to issue warnings by emitting sound and bright light;

[0067] A dual-axis synchronous servo motor 17 is used to cut off the steam delivery in the main intake pipe 5.

[0068] The intelligent controller is used to analyze and compare the first pressure sensor 10, the second pressure sensor 27 and the third pressure sensor 29, and to control the audible and visual alarm module, the first solenoid valve 9, the second solenoid valve 26 and the dual-axis synchronous servo motor 17, as well as to send real-time monitoring information to the remote control terminal.

[0069] Through the above structural design, when the pressures of the first pressure sensor 10, the second pressure sensor 27, and the third pressure sensor 29 all reach the critical value, the intelligent controller sends a signal to the audible and visual alarm module, thereby enabling personnel near the generator set to evacuate. At the same time, the intelligent controller sends an abnormal signal to the remote control terminal. After the abnormal signal is sent, the intelligent controller controls the first solenoid valve 9 and the second solenoid valve 26 to close the first diversion pipe 7 and the steam return collection pipe 24 respectively, thereby preventing damage to the device. While the solenoid valves are closed, the intelligent controller controls the dual-axis synchronous servo motor 17 to open. The dual-axis synchronous servo motor 17 drives the transmission rod 18 to rotate, which in turn drives the transmission gear 19 to rotate. The transmission gear 19 then drives the driven gear 21 to rotate, which in turn drives the rotating rod 20 to rotate. This causes the flap 22 on the surface of the rotating rod 20 to flip and open the main intake pipe 5. After one end of the main intake pipe 5 is opened, steam stops being delivered to the pressure control pipe 6, thus ensuring that the combined cycle generator set 1 is not damaged.

[0070] This invention is not limited to the above-described optional embodiments, and anyone can derive other various forms of products under the guidance of this invention.
