Description

Technical Field

[0001] This invention relates to the field of thermal power generation technology, specifically to a one-button start / stop energy-saving control device for combined cycle generator sets. Background Technology

[0002] In combined cycle generator sets, the one-button start-stop (APS) function places extremely high demands on the automation level of the auxiliary steam system. The drain device at the bottom of the auxiliary steam header is one of the key devices to ensure the safe and efficient start-up of the unit. Currently, traditional drain devices mainly rely on mechanical float drain valves, which work by using the change in condensate water level to drive the float to rise and fall, thereby directly driving the valve to open and close.

[0003] However, in practical use, the following shortcomings still exist: During a cold start-up of the APS, the condensate in the pipeline is cold and dense, resulting in a smaller buoyancy force on the float than designed, causing the actual opening water level to be higher than designed. This delays the opening of valves that should open earlier, reducing the warm-up speed and prolonging the start-up time. During a hot start-up, the condensate is hot and dense, resulting in a larger buoyancy force on the float, causing the opening water level to be lower than designed. This premature opening of valves leads to the release of a large amount of high-temperature steam, resulting in significant waste of thermal energy. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a one-button start-stop energy-saving control device for combined cycle generator sets, which has the advantage of adaptive switching for pipeline temperature, solving the problem of reduced warm-up speed or waste of high-temperature steam due to insufficient adaptability of condensate devices in cold and hot states.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a one-button start / stop energy-saving control device for a combined cycle generator set, comprising: The pipe body is installed on the drain header at the bottom of the auxiliary valve manifold in the ABS system. A control group is installed in the inner cavity of the pipe body along the hydrophobic direction. The control group includes multiple floats. The movement direction of the floats is set as a first direction. The height of the floats increases step by step along the hydrophobic direction. A first permanent magnet is fixed to the bottom of the floats through a second plate. A second permanent magnet with opposite magnetic poles is provided at the bottom of the first permanent magnet. When the temperature inside the tube changes, the float contracts at low temperatures and expands at high temperatures. A hydrophobic assembly is fixed to the outer surface of the pipe body along the hydrophobic direction. The hydrophobic assembly includes multiple second chambers. A valve is fixed in the inner cavity of each second chamber, and a valve core adapted to the valve is provided on the top of the valve. The top of the valve core is fixed to a second permanent magnet. When the water volume in the inner cavity of the pipe reaches the activity threshold of the float, the float moves in the first direction, the repulsive force between the first permanent magnet and the second permanent magnet weakens, causing the valve core to separate from the valve and draining the water from the inner cavity of the pipe. Energy dissipation components, installed at the bottom of the hydrophobic assembly, are used to buffer the mechanical energy of the water flow.

[0006] Preferably, the control group further includes a plurality of first chambers, wherein a gasket and a scraper are slidably connected to the inner cavity of the first chamber, the gasket is in contact with the scraper, the scraper is in transition fit with the inner wall of the first chamber, and the scraper scrapes the inner wall of the first chamber when it moves along a first direction.

[0007] Preferably, a first spring is fixed to the top of the gasket, and the other end of the first spring is fixedly installed in the inner cavity of the tube. The first spring is preloaded and extended, and always maintains an elastic force opposite to the first direction.

[0008] Preferably, the scraper ring is connected to the first plate, the first plate is fixed to the second plate by the first rod, and the first plate, the float and the second plate are integrally formed, so that the first plate and the second plate form a limiting structure for the float, so that the float is only allowed to undergo radial deformation.

[0009] Preferably, the float is disposed in the inner cavity of the first chamber, the float is in the shape of a corrugated tube, and after the inner cavity of the float is evacuated, it is filled with a certain amount of phase change working fluid. The working fluid in the inner cavity condenses into a liquid at low temperature and vaporizes into a gas at high temperature.

[0010] Preferably, a third plate is slidably connected to the inner cavity of the second chamber, and a second rod is fixedly installed on the top of the third plate. The second rod is fixed to the valve core. When the valve core moves in the first direction, the second rod fixes the third plates together, so that the third plates move synchronously in the first direction within the cavity of the second chamber.

[0011] Preferably, a preloaded compressed second spring is fixed to the top of the third plate, and the top of the second spring is fixed to the valve. When the third plate moves in the first direction, the second spring assists the third plate in moving in the first direction with its own elastic force.

[0012] Preferably, the hydrophobic group further includes multiple damping buffers, the output end of which is fixed to the third plate. When the third plate moves along the first direction, the damping effect generated by the damping buffers slows down the movement speed of the third plate.

[0013] Preferably, the energy dissipation component includes a shell, the inner cavity of which is integrally formed with a fourth plate, and the inner cavity of the shell has multiple channels that are connected to the second chamber. When the water-draining group drains water, a valve is used to cause the water flow to be deflected.

[0014] Preferably, a drain outlet is fixed on the side of the housing, and the drain outlet is connected to the heat exchange unit to recover and utilize the waste heat from the drain.

[0015] Beneficial effects Compared with the prior art, the present invention provides a one-button start-stop energy-saving control device for combined cycle generator sets, which has the following beneficial effects: 1. The one-button start-stop energy-saving control device of this combined cycle generator set, by designing the float as a corrugated tube and filling it with phase change working fluid, enables the float volume to adapt to temperature changes, realizes temperature compensation of buoyancy, solves the problems of delayed valve opening during cold start and premature valve opening during hot start, ensures the stability of valve opening water level under different temperature conditions, improves warm-up efficiency, and reduces high-temperature steam waste. 2. The one-button start-stop energy-saving control device of the combined cycle generator set achieves complete isolation between the water flow environment inside the pipe and the mechanical movement of the external condensate block through non-contact magnetic transmission between the first permanent magnet and the second permanent magnet. This avoids the risk of high-pressure fluid leakage along the valve stem, eliminates the friction loss present in traditional mechanical seals, and improves the reliability and service life of the device. 3. The one-button start-stop energy-saving control device of this combined cycle generator set, through the transition fit design between the scraper ring and the inner wall of the first chamber, automatically cleans the inner wall of the first chamber during each rise and reset of the float, removes impurities such as scale and rust, prevents the float from getting stuck, and ensures the long-term sensitivity and reliability of the float's movement. 4. The one-button start-stop energy-saving control device of this combined cycle generator set forms a mechanical hysteresis range through the synergistic effect of the damping buffer and the spring. Combined with the arrangement of the float with the height gradually increasing along the condensate drainage direction, it effectively filters out false water level signals caused by small fluctuations in the rate of condensate generation, prevents high-frequency vibration of the valve core, eliminates the vibration phenomenon of frequent opening and closing, and reduces the waste of high-temperature steam caused by frequent valve opening and closing. 5. The one-button start-stop energy-saving control device of this combined cycle generator set uses the fourth plate in the energy dissipation component to cause multiple deflections of the high-pressure condensate, which consumes the kinetic energy of the water flow step by step, effectively preventing the water hammer effect and protecting downstream pipelines and equipment from impact damage. At the same time, it connects to the heat exchange unit through the condensate outlet to recover and utilize waste heat, reducing thermal pollution and heat energy waste. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] In the description of this invention, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0029] In addition, a fixed connection refers to a connection in which parts or components are fixed and there is no relative movement; a transmission connection refers to a connection in which mechanical motion or torque is transmitted to other working parts through a transmission component; a sliding connection refers to a connection in which two objects are in contact but not fixed and can slide relative to each other; and a rotational connection refers to a connection in which two objects are in contact but not fixed and can rotate relative to each other.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified. Please see Figure 1-10 The device includes, in sequence along the drainage direction, a pipe body 100, a control group 200, a drainage group 300, and an energy dissipation component 400. The pipe body 100 is installed on the drainage header at the bottom of the auxiliary steam header in the ABS, serving as the main structure of the entire device. The control group 200 is installed in the inner cavity of the pipe body 100 along the drainage direction to sense changes in water level and temperature inside the pipe. The drainage group 300 is fixed on the outer surface of the pipe body 100 along the drainage direction, corresponding to the position of the control group 200, and is used to perform drainage actions. The energy dissipation component 400 is installed at the bottom of the drainage group 300 to buffer the discharged drainage. Furthermore, when the existing condensate drain device is started in cold and hot conditions, the buoyancy of the float 220 changes due to the temperature and density difference of the condensate, which causes the opening water level of the valve 311 to deviate, resulting in a decrease in the warm-up speed or waste of high-temperature steam. like Figure 3 and Figure 7 As shown, the control group 200 includes multiple first chambers 210 and multiple floats 220. The floats 220 are disposed in the inner cavity of the first chambers 210, and their direction of movement is defined as a first direction ( Figure 7(In the direction indicated by the middle arrow) Multiple floats 220 increase in height progressively along the hydrophobic direction to adapt to the control requirements of different water level gradients. The floats 220 are corrugated tubes, and their inner cavities are evacuated and filled with a certain amount of phase change working fluid. This working fluid condenses into a liquid at low temperatures and vaporizes into a gas at high temperatures, causing the floats 220 to contract at low temperatures and expand at high temperatures. Through the design of the phase change working fluid, the volume of the floats 220 can adaptively adjust with temperature changes. When starting from a cold state, the low temperature causes the floats 220 to contract and the buoyancy to decrease, and its displacement decreases accordingly. A higher water level is required for it to float, thereby automatically raising the opening water level threshold of valve 311 to counteract the low temperature. The high density of condensate has a negative impact on buoyancy. During hot start-up, the high temperature causes the float 220 to expand, increasing buoyancy and correspondingly increasing its drainage. It can trigger buoyancy at a lower water level, thereby automatically reducing the opening water level threshold of valve 311 and offsetting the negative impact of the low density of high-temperature condensate on buoyancy. Through the structure of the float 220 and the inner cavity filled with working fluid, it can solve the problem of reduced warm-up speed caused by delayed opening of valve 311 during cold start-up, and the problem of high-temperature steam waste caused by premature opening of valve 311 during hot start-up. This achieves temperature adaptive compensation of buoyancy and ensures the stability of the opening water level of valve 311 under different temperature conditions. like Figure 3 As shown, a first permanent magnet 222 is fixed to the bottom of the float 220 via a second plate 221. A second permanent magnet 223 with opposite magnetic poles is provided at the bottom of the first permanent magnet 222. The first permanent magnet 222 and the second permanent magnet 223 are connected by non-contact magnetic transmission, which generates a constant repulsive force between the first permanent magnet 222 and the second permanent magnet 223. The repulsive force between the first permanent magnet 222 and the second permanent magnet 223 forms a magnetic limiting structure for the second permanent magnet 223. At the same time, the water flow environment inside the pipe 100 is completely isolated from the mechanical movement of the external drainage assembly 300, avoiding the risk of high-pressure fluid leakage along the valve stem and eliminating the frictional loss present in traditional mechanical seals. like Figure 4As shown, the first plate 214, float 220, and second plate 221 are integrally formed through a composite process, which can be laser welding, vacuum brazing, or other preferred processes. This process seals the working fluid inside the cavity of the float 220. The first plate 214 and the second plate 221 are fixedly connected by the first rod 224, forming a limiting structure relative to the float 220. This allows the float 220 to only undergo radial deformation, ensuring the stability of its volume change and the accuracy of its movement along the first direction. This prevents the float 220 from undergoing unexpected radial offset or twisting, causing a change in the preset gap between the first permanent magnet 222 and the second permanent magnet 223. This ensures the consistency of deformation during the expansion and contraction of the float 220, and converts all the buoyancy generated by the float 220 into driving force along the first direction, avoiding jamming or response delay caused by skewness. like Figure 3 As shown, a gasket 212 and a scraper ring 213 are slidably connected to the inner cavity of the first chamber 210. The scraper ring 213 is in transition fit with the inner wall of the first chamber 210. Through the design of the scraper ring 213, the inner wall of the first chamber 210 can be automatically cleaned during each rise and fall and reset of the float 220, removing scale, rust, or impurities that may have adhered to the inner wall during long-term operation. This not only prevents the float 220 from being obstructed or jammed due to the accumulation of dirt, but also ensures the long-term operation of the float 220. Sensitivity and reliability are improved, and the buoyancy response deviation caused by increased frictional resistance is reduced. A first spring 211 is fixed on the top of the gasket 212. The other end of the first spring 211 is fixedly installed in the inner cavity of the tube body 100. The first spring 211 is preloaded and extended, and always maintains an elastic force opposite to the first direction. It is used to assist the float 220 in resetting when the water volume decreases. The scraper ring 213 is connected to the first plate 214. When the scraper ring 213 moves in the first direction, it can scrape the inner wall of the first chamber 210. like Figure 6As shown, the hydrophobic assembly 300 includes multiple second chambers 310. Each second chamber 310 has a valve 311 inside, and a valve core 312 adapted to the valve 311 is located on its top. The connection between the valve 311 and the valve core 312 allows the valve 311 to control the flow of water. The top of the valve core 312 is fixed to the second permanent magnet 223 in the control assembly 200. When the first permanent magnet 222 moves along a first direction, the repulsive force between the first permanent magnet 222 and the second permanent magnet 223 weakens, thus relatively weakening the magnetic limit relative to the second permanent magnet 223. A third plate 314 is slidably connected to the inner cavity of the second chamber 310. A second rod 313 is fixedly installed on the top of 4. The second rod 313 is fixed to the valve core 312. When the valve core 312 moves in the first direction, the second rod 313 is fixedly connected to the third plate 314, so that the third plate 314 moves synchronously in the first direction in the cavity of the second chamber 310. The third plate 314 has multiple through holes to guide the water flow and prevent interference with the water flow. At the same time, it reduces the contact area under the impact of the water flow and prevents the third plate 314 from affecting the valve core 312. That is, under the influence of the kinetic energy of the water flow, the third plate 314 causes the valve core 312 to move in the opposite direction in the first direction, causing fluctuations in the opening of the valve 311. like Figure 6 As shown, a preloaded second spring 315 is fixed to the top of the third plate 314. The top of the second spring 315 is fixed to the valve 311. When the third plate 314 moves in the first direction, the second spring 315 assists the third plate 314 in moving in the first direction with its own elastic force, ensuring that the valve core 312 can open quickly. The preload elastic force of the second spring 315 ensures that the valve 311 can start quickly when the water level reaches the threshold, avoiding excessive water accumulation caused by response delay. The drainage group 300 also includes multiple damping buffers 320. The output end of the damping buffer 320 is fixed to the third plate 314. When the third plate 314 moves in the first direction, the damping buffer 320 generates a damping effect, which slows down the movement speed of the third plate 314. The damping buffer 320 controls the opening speed of the valve core 312, so that the valve 311 opens gradually. This can prevent the water hammer shock wave generated by instantaneous full opening from damaging the valve seat and pipeline, and also avoid the discharge of a large amount of high-temperature steam with the condensate due to excessive opening, thus preventing the valve 311 from impacting the system by instantaneous full opening. In summary, when the water level inside the pipe 100 reaches the activity threshold of the float 220, the float 220, under the action of buoyancy, overcomes the elastic force of the first spring 211 and floats upward in the first direction. As the float 220 floats upward, the distance between the first permanent magnet 222 and the second permanent magnet 223 increases, and the repulsive force between them weakens. Under the action of its own weight and the elastic force of the second spring 315, the second permanent magnet 223 drives the valve core 312 to move upward, causing the valve core 312 to separate from the valve 311, opening the drainage passage, and draining water from the inside of the pipe 100. Through the linkage of the float 220, the permanent magnet assembly, and the valve 311, the opening and closing of the drainage valve 311 can be automatically and precisely controlled according to changes in water level, thus achieving… The passive, automatic drainage without external control signals reduces the dependence on the unit control system. It can also flexibly set the opening water level threshold of valve 311 by adjusting the initial distance between the first permanent magnet 222 and the second permanent magnet 223 or by replacing the magnetic metal with different magnetic forces. This allows the same device to be adapted to pipeline systems with different pressure levels and drainage flow rates, ensuring the overall versatility and adaptability. At the same time, the progressively increasing arrangement of floats 220 allows floats 220 at different heights to trigger the corresponding valves 311 in sequence, achieving graded and sequential drainage. This can meet the continuous drainage needs under low flow conditions and quickly open multiple valves 311 to increase drainage capacity when there is a large flow of water accumulation. Furthermore, when the unit load is stable but the condensate production rate fluctuates slightly, the water level in the pipe body 100 may oscillate repeatedly near the opening threshold of a single valve 311. If the valve core 312 responds too quickly, it will cause the valve 311 to frequently open and close, and each brief opening will release a stream of high-temperature steam. At the same time, the sealing surface of the valve core 312 will wear faster due to repeated impacts. like Figure 5 As shown, a mechanical hysteresis range is formed through the synergistic action of the damping buffer 320 and the second spring 315. When the water level rises to the opening threshold, as... Figure 7 As shown, the float 220 rises, increasing the distance between the first permanent magnet 222 and the second permanent magnet 223, thus weakening the repulsive force. At this time, the third plate 314 moves along the first direction under the preload force of the second spring 315. However, due to the presence of the damping buffer 320, the movement speed of the third plate 314 is limited to a low value. The valve core 312 will not jump open instantly, but will gradually open at a controllable rate. If the water level drops briefly due to the opening of the valve 311, since the valve core 312 has not completely left the valve 311, the float 220 only needs to drop slightly to strengthen the magnetic repulsive force again and push the valve core 312 back to the closed position. like Figure 5 and Figure 6As shown, by adjusting the damping coefficient of the damping buffer 320 and the preload of the second spring 315, the opening action of the valve core 312 can be delayed in response to the water level change, and the closing action can also be delayed, thereby forming an insensitive zone near the opening threshold. The insensitive zone is defined as a hysteresis loop. When the width of the hysteresis loop is greater than the amplitude of the water level fluctuation, the valve core 312 will not respond to every tiny fluctuation, thus fundamentally eliminating the shaking. like Figure 2 As shown, the arrangement of multiple floats 220 with progressively increasing height along the drainage direction allows different water levels to correspond to different valves 311. The lowest float 220 corresponds to the first-level valve 311. Only when the water level continues to rise will the second-level valve 311 and the third-level valve 311 be triggered in sequence. When the water level fluctuates slightly near a certain threshold, only the valve core 312 of that level valve 311 may actuate, while other valves 311 remain in their original state, further reducing the overall actuation frequency. Even if a certain level valve 311 is briefly opened due to disturbance, the amount of drainage it discharges is very small and insufficient to impact the system pressure. Once the water level recovers, the valve 311 closes, without triggering a chain response from adjacent valves 311. Through the above design combining damping hysteresis and multi-level threshold, false water level signals caused by small fluctuations in condensate production rate are effectively filtered out, preventing high-frequency vibration of valve core 312, ensuring that valves 311 at all levels open reliably in sequence when the real water level continues to rise, taking into account both anti-disturbance capability and large flow discharge capability. Furthermore, the existing drainage device discharges high-pressure drainage directly at the moment valve 311 is opened, which can easily generate water hammer effect, damaging pipeline equipment and causing a large amount of heat energy waste. like Figure 9 and Figure 10 As shown, the energy dissipation component 400 includes a housing 410, and the inner cavity of the housing 410 is integrally formed with a fourth plate 411. When the hydrophobic assembly 300 performs hydrophobic drainage, the high-pressure hydrophobic water first enters the housing 410 and is blocked by the fourth plate 411, resulting in multiple deflections. The fourth plate 411 causes the high-speed water flow to undergo multiple deflections. Each deflection is accompanied by a sudden change in flow direction and the consumption of water kinetic energy, which gradually reduces the pressure and speed of the water flow, effectively preventing the generation of water hammer effect and protecting downstream pipelines and equipment from impact damage. At the same time, by utilizing the turbulence and retention effect formed during the deflection process, the vapor bubbles in the hydrophobic water have sufficient time to burst and release latent heat, thereby improving the efficiency of subsequent heat recovery. The inner cavity of the shell 410 is provided with multiple channels 413, which are connected to the second chamber 310. A drain port 412 is fixed on the side of the shell 410 and is connected to the heat exchange unit. After being buffered and dissipated, the drain water is guided to the heat exchange unit through the drain port 412. The heat exchange unit is a heat recovery device existing in the prior art, which recovers and utilizes the waste heat, reduces the heat pollution emitted to the environment, and converts the originally wasted heat energy into useful heat that can be used to preheat condensate or other process steps.
