Description

Technical Field

[0001] This invention relates to the field of gas turbine intake air heating technology, specifically to a gas turbine intake air heating device. Background Technology

[0002] Gas turbines, as efficient and clean power equipment, are widely used in fields such as power generation. The stable operation of their air intake system is the core prerequisite for ensuring the power generation efficiency and safety of the unit. Among them, the bag filter, as the first filtration barrier for the gas turbine air intake, can effectively intercept dust and impurities in the air and prevent them from entering core components such as the compressor, causing wear and scale buildup. This is of great significance for extending the life of the unit and maintaining the stability of the thermodynamic cycle.

[0003] In actual operation, the gas turbine intake heating system is highly susceptible to environmental and meteorological conditions, especially under low temperature and high humidity conditions. When the ambient temperature is below the air dew point and the relative humidity is high, a large amount of water vapor carried by the cold air will undergo a phase change on the surface of the bag filter element. Initially, this manifests as frost forming between the filter element fibers. As the temperature continues to decrease or the humidity further increases, the frost layer will gradually freeze into ice, forming a dense ice blockage layer, which will cause the filter element to become clogged and the intake resistance to increase sharply. In severe cases, it may lead to filter element failure, unit load reduction, or even unplanned shutdown.

[0004] To address the above issues, a gas turbine intake heating device was proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a gas turbine intake air heating device. By using this device, the problem mentioned above can be solved: when the ambient temperature is lower than the air dew point and the relative humidity is high, a large amount of water vapor carried by the cold air will undergo a phase change on the surface of the bag filter element, forming a dense ice blockage layer, which leads to filter element blockage.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A gas turbine intake heating device includes a support frame. An intake shell is fixedly installed on one side of the support frame. An intake component is installed inside the intake shell, and one end of the intake component is connected through to one side of the intake shell. An exhaust component is connected to one end of the intake component, and an air delivery component is provided at one end of the exhaust component. The air delivery component is fixedly connected to the support frame. A housing is fixedly installed on one side of the intake shell. A filter plate is installed inside the housing. Several guide plates are installed on one side of the housing. A first guide hood is installed on one side of the housing. A spiral tube is connected to one side of the first guide hood. A second guide hood is provided near one end of the spiral tube on the side close to the air delivery component. A driving component is provided on the surface of the spiral tube. An electromagnetic component is rotatably connected to the surface of the spiral tube, and the driving component and the electromagnetic component are connected in a transmission manner.

[0007] Furthermore, an air intake channel is provided inside the air intake shell.

[0008] Furthermore, the air intake component includes a pipe frame and several first branch pipes connected to one side of the pipe frame. Several air intake heads are connected to one side of the first branch pipes, and a second branch pipe is connected to one side of the pipe frame. The second branch pipes are connected through and connected to one side of the air intake housing, and a shut-off valve is provided on one side of the second branch pipes.

[0009] Furthermore, the air extraction component includes a pump body and a connecting pipe disposed on one side of the pump body, and the connecting pipe is connected to the second branch pipe.

[0010] Furthermore, the gas transmission component includes an L-shaped pipe and several third branch pipes connected to one side of the L-shaped pipe. The L-shaped pipe is connected to the pump body. A support rod is fixedly installed at one end of the third branch pipe. Several silencer nozzles are installed on one side of the third branch pipe. A fixing frame is fixedly installed on one side of the L-shaped pipe, and the fixing frame is fixedly connected to the support rod and the support frame.

[0011] Furthermore, an exhaust pipe is connected to one side of the housing, and a solenoid valve is provided on one side of the exhaust pipe.

[0012] Furthermore, four connecting plates are fixedly installed on one side of the first air deflector, and all four connecting plates are fixedly connected to the second air deflector.

[0013] Furthermore, the spiral tube has several spiral grooves inside.

[0014] Furthermore, the driving component includes a base and a motor fixed to one side of the base. The base is fixedly connected to the spiral tube, and a gear is fixedly connected to the output end of the motor.

[0015] Furthermore, the electromagnetic component includes an annular plate and an annular coil fixed inside the annular plate. A high-frequency power supply is fixedly installed on one side of the annular plate and is electrically connected to the annular coil through a wire. A protective shell is provided outside the high-frequency power supply and is fixedly connected to the annular plate. An annular toothed plate is fixedly installed on the other side of the annular plate and the gear meshes with the annular toothed plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The exhaust gas from the final stage of the gas turbine compressor is used directly as the heating source, eliminating the need for additional independent heat source equipment such as electric heaters and waste heat exchangers. This enables the cascade recovery and reuse of the gas turbine's own energy, thereby improving the overall energy utilization efficiency of the combined cycle gas turbine.

[0017] 2. The second guide shroud can converge the low-temperature ambient air and the high-temperature gas injected by the gas delivery component, so that the two airflows form a preliminary convective mixing before entering the spiral tube, which improves the basic efficiency of subsequent mixing. The spiral structure inside the spiral tube can force the airflow to form a swirling flow, so that the high-temperature gas and low-temperature air will generate intense shearing and heat exchange during the swirling process, achieving efficient and uniform mixing at the mechanical level and avoiding local temperature imbalance caused by airflow stratification.

[0018] 3. Through a dual mixing mechanism of mechanical swirling and alternating electromagnetic turbulence, high-temperature gas and low-temperature air are fully mixed, ensuring that the airflow temperature entering the shell is uniform and above the freezing point. This eliminates the phenomenon of water vapor frosting and freezing on the filter plate surface from the root, and avoids the problem of sudden increase in air intake resistance caused by filter plate pore blockage.

[0019] 4. The dynamic electromagnetic field can quickly dissolve the tiny ice crystals and droplets remaining in the airflow, preventing them from accumulating in the gaps between the filter plate fibers and avoiding filter element failure caused by ice blockage; at the same time, it ensures stable air intake and improves the safety of unit operation.

[0020] 5. The dual mixing mechanism overcomes the drawbacks of airflow stratification, making the airflow temperature field and velocity field distribution uniform. Combined with the rectification effect of the first guide vane, it reduces the aerodynamic vibration amplitude of the components and extends the service life of the core components of the intake system.

Detailed Implementation

[0023] 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.

[0024] To address the technical problem of filter clogging caused by a large amount of water vapor carried by cold air undergoing a phase change on the surface of the coarse filter element when the ambient temperature is below the air dew point and the relative humidity is high, resulting in a dense ice blockage layer, such as... Figures 1-8 As shown, the following preferred technical solutions are provided: like Figure 1 and Figure 4 As shown, the gas turbine intake heating device includes a support frame 1. An intake shell 2 is fixedly installed on one side of the support frame 1. The support frame 1 serves as the basic load-bearing component of the device, providing stable fixation for core components such as the intake shell 2. This ensures that all components maintain a stable installation posture under the conditions of high airflow impact and high-frequency vibration in the gas turbine intake system. An intake component 3 is installed inside the intake shell 2, with one end of the intake component 3 penetrating and connecting to one side of the intake shell 2. The intake shell 2 serves as the connection hub to the final stage of the gas turbine compressor, enabling the stable introduction of high-temperature, high-pressure exhaust gas. The intake component 3 undertakes the initial guiding and conveying function of the high-temperature gas. The flow rate of the final stage exhaust gas from the compressor is initially stabilized to ensure the stability of subsequent heat source extraction. The two work together to achieve local heat extraction, directly utilizing the waste heat of the gas turbine's own exhaust as a heating source. There is no need to configure additional independent heat source equipment, which greatly reduces the initial investment and subsequent operating energy consumption of the device. This is in line with the energy-saving concept of energy cascade utilization. One end of the air inlet 3 is connected to the air extraction component 4, and the other end of the air extraction component 4 is equipped with the air delivery component 5. The air delivery component 5 is fixedly connected to the support frame 1. The air extraction component 4 can precisely control the extraction flow rate of high-temperature exhaust gas. In conjunction with the air delivery component 5, the extracted high-temperature gas can be directionally delivered to the airflow mixing area.

[0025] A housing 6 is fixedly installed on one side of the intake housing 2. A filter plate 7 is installed inside the housing 6. The housing 6 provides a stable installation and working space for the filter plate 7. Its sealed structure prevents unfiltered air from directly entering the gas turbine intake end, while also buffering the mixed and heated airflow to avoid high-speed airflow directly impacting the filter plate 7 and causing filter element damage, thus extending the service life of the filter plate 7. Several guide plates 8 are installed on one side of the housing 6. The mixed and heated airflow passes through the guide plates 8 to achieve a regular flow direction, which can straighten the turbulent airflow into a uniform laminar flow, ensuring a stable and uniform airflow velocity entering the housing 6, and avoiding localized wear of the filter plate 7 due to uneven airflow impact angles. A first guide shroud 9 is installed on one side of the housing 6. A spiral tube 10 is connected to one side of the first guide shroud 9. One end of the spiral tube 10, near the gas delivery component 5, is connected to... A second guide shroud 20 is provided, which can gather the low-temperature ambient air and the high-temperature gas injected by the gas delivery component 5, and accelerate the airflow velocity through a contraction structure, so that the two airflows form a preliminary convective mixing before entering the spiral tube 10, thereby improving the basic efficiency of subsequent mixing. The spiral structure inside the spiral tube 10 can force the airflow to form a swirling flow, so that the high-temperature gas and low-temperature air will generate intense shearing and heat exchange during the swirling process, achieving efficient and uniform mixing at the mechanical level, avoiding local temperature imbalance caused by airflow stratification, and preventing frost and ice formation on the surface of the filter plate 7 from the source. The first guide shroud 9 can rectify the swirling airflow discharged from the spiral tube 10, counteract the centrifugal force of the swirling flow, restore the airflow to a stable laminar flow state, and prevent the swirling flow from directly impacting the guide plate 8 and the filter plate 7, thereby reducing aerodynamic noise and the risk of component impact damage.

[0026] A driving element 30 is provided on the surface of the spiral tube 10, and an electromagnetic element 40 is rotatably connected to the surface of the spiral tube 10. The driving element 30 and the electromagnetic element 40 are connected in a transmission manner. The driving element 30 can drive the electromagnetic element 40 to rotate on the surface of the spiral tube 10, providing power support for the generation of dynamic electromagnetic field. The dynamic alternating electromagnetic field generated when the electromagnetic element 40 rotates can drive the airflow in the spiral tube 10 to form a composite motion of mechanical swirling flow and alternating electromagnetic turbulence, breaking the mixing blind zone of mechanical swirling flow and realizing full-dimensional mixing without dead angles. At the same time, the electromagnetic field can polarize the tiny droplets and ice crystals in the airflow, accelerate their collision and evaporation, completely eliminate low-temperature solid phase impurities, and ensure the uniformity of the intake air temperature. In addition, the dynamic electromagnetic field can also suppress the disorderly development of airflow turbulence, reduce aerodynamic noise, and improve the plant operating environment.

[0027] The inlet casing 2 of the device is connected to the last stage of the gas turbine compressor. The high-temperature and high-pressure exhaust gas generated by the last stage of the compressor first enters the inlet component 3 through the inlet casing 2. Then, through the synergistic action of the inlet component 3 and the extraction component 4, it is stably extracted and transported to the gas delivery component 5. This can directionally transport the high-temperature heat source to the intake mixing area, providing a stable heat source for subsequent airflow mixing. The high-temperature gas ejected from the gas delivery component 5 enters the second guide shroud 20 simultaneously with the low-temperature ambient air entering the gas turbine intake system. The second guide shroud 20 has a contraction structure, which can converge the two airflows and guide them to the spiral tube 10 with a smaller cross-sectional area, thereby increasing the airflow velocity and forming a high-speed airflow channel. After the airflow enters the spiral tube 10, its internal spiral structure will force the airflow to form a swirling flow, causing the high-temperature gas and low-temperature air to generate violent shearing and convection during the swirling process, completing the initial mechanical mixing, realizing rapid heat transfer, and initially increasing the overall temperature of the airflow.

[0028] While mechanical swirling mixing occurs, the drive component 30 drives the electromagnetic component 40 to rotate on the surface of the spiral tube 10, causing the electromagnetic component 40 to generate a dynamically alternating electromagnetic field. This field drives the airflow molecules within the spiral tube 10 to form a composite motion of mechanical swirling and alternating electromagnetic disturbance. On one hand, the alternating electromagnetic field breaks the possible mixing blind zone of mechanical swirling, allowing high-temperature gas and low-temperature air to achieve full-dimensional and dead-angle mixing. On the other hand, the electromagnetic field polarizes the tiny droplets and ice crystals in the airflow, accelerating their collision and aggregation and rapid evaporation or melting, thus completely eliminating low-temperature solid impurities in the airflow. The uniform airflow after electromagnetic enhancement mixing first completes swirling rectification through the first guide shroud 9, stabilizing the airflow velocity and direction. Then, guided by the guide plate 8, it enters the interior of the shell 6 and finally enters the gas turbine intake end after being filtered by the filter plate 7, completing the entire intake heating and purification process.

[0029] Therefore, the device directly uses the exhaust gas from the final stage of the gas turbine compressor as a heat source, which is rapidly mixed with the low-temperature ambient air entering the intake system. This ensures that the intake air temperature does not affect the unit's operation, eliminates the risk of ice blockage on filter plate 7, and raises the intake air temperature above the freezing point through front-end heating, thus completely solving the ice blockage problem of the first-stage filter plate 7. At the same time, through the dual mixing mechanism of mechanical swirl and electromagnetic turbulence, the high-temperature heat source and low-temperature air can be fully mixed, ensuring that the airflow temperature entering the casing 6 is uniform and above the freezing point. This fundamentally avoids the phenomenon of water vapor frosting and freezing on the surface of filter plate 7, and eliminates the problem of sudden increase in intake resistance caused by the blockage of the filter plate 7 pores. The dynamic electromagnetic field can quickly melt the tiny ice crystals and droplets remaining in the airflow, preventing them from accumulating in the fiber gaps of filter plate 7, avoiding the risk of filter element failure caused by ice blockage, and eliminating safety hazards such as unit load reduction and unplanned shutdown caused by insufficient intake air volume.

[0030] like Figure 2As shown, an intake channel 21 is provided inside the intake housing 2. The intake channel 21 provides a dedicated flow path for the high-temperature and high-pressure exhaust gas of the final stage of the gas turbine compressor. It can accurately guide the high-temperature gas discharged from the final stage of the compressor to the intake component 3, avoid the disorderly diffusion of the high-temperature airflow inside the intake housing 2, and ensure that the heat source can enter the subsequent extraction component 4 and the gas delivery component 5 efficiently and directionally, providing a stable heat supply for the entire intake heating process.

[0031] The air intake component 3 includes a pipe frame 31 and several first branch pipes 32 connected to one side of the pipe frame 31. Several air inlets 33 are connected to one side of each first branch pipe 32. The multiple first branch pipes 32, in conjunction with the multiple air inlets 33, enable multi-point and dispersed air intake of high-temperature gas, allowing the high-temperature exhaust gas to enter the air intake channel 21 of the air intake shell 2 evenly. This avoids flow field turbulence caused by localized concentration of high-temperature gas and maximizes the contact area between the high-temperature heat source and the subsequent low-temperature ambient air, laying a good foundation for subsequent airflow mixing. The pipe frame 31 has one side... The system is connected to a second branch pipe 34, which runs through and connects to one side of the air inlet shell 2. A shut-off valve 35 is installed on one side of the second branch pipe 34. The pipe frame 31 has a frame structure, which can initially divert the high-temperature and high-pressure exhaust gas delivered by the second branch pipe 34. Then, through multiple first branch pipes 32 connected to its side wall, the heat source is evenly distributed, avoiding the imbalance of heat source supply caused by excessive or insufficient air intake in a single branch. This ensures that each subsequent air inlet head 33 can output a stable flow of high-temperature gas, providing a basic guarantee for the heat balance of the overall heating system.

[0032] The extraction component 4 includes a pump body 41 and a connecting pipe 42 disposed on one side of the pump body 41. The pump body 41 is made of special materials and sealing structure that are resistant to high temperature and high pressure. It can withstand the high temperature and high pressure impact of the final stage exhaust of the compressor and avoid failures such as sealing failure and component deformation caused by high temperature gas baking or high pressure airflow impact. The connecting pipe 42 is connected to the second branch pipe 34. The connecting pipe 42 serves as the connection link between the pump body 41 and the second branch pipe 34, providing a sealed dedicated transmission channel for high temperature exhaust. It can accurately and leak-free deliver the high temperature gas extracted by the pump body 41 to the intake component 3.

[0033] like Figure 5As shown, the gas delivery component 5 includes an L-shaped pipe 51 and several third branch pipes 52 connected to one side of the L-shaped pipe 51. The L-shaped pipe 51 is connected to the pump body 41. The L-shaped pipe 51 is made of a high-temperature and high-pressure resistant alloy material, which can withstand the high temperature and high pressure impact of the compressor's final stage exhaust, preventing the pipeline from deforming and cracking due to long-term thermal stress and pressure. One end of each third branch pipe 52 is fixedly equipped with a support rod 53. Multiple third branch pipes 52 can synchronously deliver high-temperature gas to different areas of the second guide shroud 20, realizing multi-point, full-area coverage injection of the high-temperature heat source, allowing the high-temperature gas to fully contact the incoming low-temperature ambient air, avoiding uneven mixing caused by the lack of local heat sources, and improving the overall performance. To improve the efficiency and uniformity of the heating and mixing process, several silencer nozzles 54 are installed on one side of the third branch pipe 52, and a fixing bracket 55 is fixedly installed on one side of the L-shaped pipe 51. The fixing brackets 55 are all fixedly connected to the support rod 53 and the support frame 1. The diffuser nozzle design of the silencer nozzles 54 reduces the whistling and vortex noise during gas injection. Combined with the swirling noise reduction of the subsequent spiral pipe 10, the overall noise of the intake system is significantly reduced. It can atomize high-temperature gas into fine airflow jets, increase the contact area with low-temperature ambient air, accelerate heat transfer and airflow mixing, avoid the formation of local hot spots in high-temperature gas, further improve the mixing uniformity, and eliminate local thermal damage to the guide plate 8 and filter plate 7 from the source.

[0034] like Figure 3 As shown, an exhaust pipe 61 is connected to one side of the housing 6, and a solenoid valve 62 is installed on one side of the exhaust pipe 61. The exhaust pipe 61 provides a dedicated flow channel for the airflow that has been filtered by the filter plate 7 and heated and mixed. It can accurately guide the clean airflow with uniform temperature and qualified impurities to the gas turbine inlet. The exhaust pipe 61 can be made of heat-insulating material or have an additional heat insulation layer to reduce the heat loss of the heated airflow during the transportation process, ensure that the inlet air temperature entering the gas turbine meets the requirements of anti-icing and unit operation, and maximize the retention of the heat value of the previous heating stage. The solenoid valve 62 can automatically adjust the valve opening according to the real-time operating load of the gas turbine, ambient temperature and other operating parameters to accurately control the inlet air flow into the gas turbine.

[0035] like Figure 4 As shown, four connecting plates 91 are fixedly installed on one side of the first guide shroud 9, and all four connecting plates 91 are fixedly connected to the second guide shroud 20. The four connecting plates 91 are symmetrically distributed at the connection between the first guide shroud 9 and the second guide shroud 20, which can firmly lock the first guide shroud 9 and the second guide shroud 20 to form an integrated airflow guiding component. This multi-point symmetrical connection method can evenly disperse the stress generated by the airflow impact, avoid the breakage or deformation of a single connection point due to the concentration of force, and especially resist the backlash force brought by the high-speed swirling airflow in the spiral tube 10, ensuring that the guide shroud maintains a stable installation posture during long-term high-load operation, and preventing airflow leakage or flow field disturbance caused by the misalignment of the guide shroud.

[0036] like Figure 6 As shown, the spiral tube 10 has several spiral grooves 101 inside. The spiral guide structure of the spiral grooves 101 forces the high-temperature gas and low-temperature ambient air entering the tube to move forward in a spiral motion along the groove, breaking the stratification of the two airflows and causing them to generate intense shearing, convection and mixing. Compared with a straight tube without spiral grooves 101, the spiral grooves 101 can significantly increase the contact area and contact time of the airflow, allowing the high-temperature heat to be quickly transferred to the low-temperature air, achieving uniform mixing throughout the entire pipeline, completely avoiding the formation of local low-temperature areas, and eliminating the risk of frost and ice formation on the surface of the guide plate 8 and filter plate 7 from the root. Secondly, the spiral path of the spiral grooves 101 extends the flow path of the airflow in the tube, which is equivalent to increasing the effective length of heat exchange, allowing the waste heat of the high-temperature gas to be fully released, maximizing the thermal energy utilization rate, and ensuring that the intake temperature after mixing is stably higher than the freezing point, meeting the core requirements of gas turbine intake anti-icing.

[0037] To address the technical challenges of mixing blind zones in mechanical swirl flow, and the presence of micro-droplets and ice crystals in the airflow, which easily lead to low-temperature solid impurities and reduce inlet air temperature uniformity, such as... Figures 7-8 As shown, the following preferred technical solutions are provided: like Figure 8 As shown, the drive unit 30 includes a base 301 and a motor 302 fixed to one side of the base 301. The base 301 is fixedly connected to the spiral tube 10. A gear 303 is fixedly connected to the output end of the motor 302. The motor 302 can output a continuous and controllable torque, which drives the electromagnetic component 40 to rotate stably through the gear 303, providing the core power for the generation of dynamic alternating electromagnetic fields. Its speed regulation function can flexibly adjust the speed according to the working conditions. For example, under extremely cold and humid conditions, the speed can be increased to enhance the alternating frequency of the electromagnetic field to strengthen the airflow mixing effect. When the temperature is high and strong mixing is not required, the speed can be reduced to reduce energy consumption, realize flexible control of power output, and adapt to the operating requirements of different climates and unit loads.

[0038] like Figure 7The electromagnetic component 40 shown includes an annular plate 401 and an annular coil 402 fixed inside the annular plate 401. A high-frequency power supply 403 is fixedly installed on one side of the annular plate 401, and the high-frequency power supply 403 is electrically connected to the annular coil 402 through a wire. The high-frequency power supply 403 can provide a stable high-frequency current to the annular coil 402, ensuring that the strength and frequency of the electromagnetic field are always within a controllable range, avoiding electromagnetic field failure due to voltage fluctuations, and ensuring the continuity and stability of electromagnetic enhancement mixing. A protective shell 404 is provided outside the high-frequency power supply 403, and the protective shell 404 is fixedly connected to the annular plate 401. The protective shell 404 can provide physical protection for the high-frequency power supply 403, isolating it from external corrosive and impurity media such as water vapor, salt spray, and dust, preventing short circuits or component corrosion inside the high-frequency power supply 403, and is especially suitable for coastal areas. In high humidity and high salt spray conditions, the high frequency power supply 403 is significantly improved in terms of operational stability and service life. An annular toothed plate 405 is fixedly installed on the other side of the annular plate 401, and the gear 303 is meshed with the annular toothed plate 405. The annular coil 402 can generate a high frequency electromagnetic field under the power supply of the high frequency power supply 403. The motor 302 can drive the gear 303 to rotate. The gear 303 and the annular toothed plate 405 cooperate to make the annular plate 401 rotate, forming a dynamic alternating electromagnetic field. This electromagnetic field can drive the airflow in the spiral tube 10 to form a composite motion of mechanical swirling and alternating electromagnetic turbulence, breaking the blind zone of mechanical mixing and realizing full-dimensional mixing of high temperature gas and low temperature air without dead angles. At the same time, the electromagnetic field can polarize the tiny droplets and ice crystals in the airflow, accelerate their collision and evaporation, completely eliminate the hidden danger of ice blockage, and ensure the uniformity of the intake temperature.
