Description

Technical Field

[0001] This invention relates to the field of gas turbine inlet equipment technology, and more particularly to an inlet device for maintaining a constant inlet temperature for a gas turbine. Background Technology

[0002] Gas turbines are core power equipment in power generation, aviation, and industrial drive fields. Their operating efficiency, stability, and service life are closely related to the quality of the intake air. The ambient air temperature and humidity fluctuate greatly. When high-temperature and high-humidity air enters the gas turbine, it not only reduces the intake air density and the unit's working efficiency, but also causes a large amount of water vapor and tiny liquid water mist in the air to enter the intake filter element with the airflow.

[0003] Most existing gas turbine intake systems only have simple filtration functions and lack effective temperature control and dehumidification / impurity removal structures. They cannot maintain a constant intake temperature, nor can they remove liquid water, excess moisture, and impurities from the air. When high-humidity, liquid-containing air flows through the filter element, it absorbs moisture and becomes damp. Combined with dust and impurities in the air, this easily clumps together to form mud, causing filter blockage and filtration failure. This not only significantly shortens the filter element's lifespan and increases equipment maintenance costs, but also leads to insufficient intake volume, excessive intake impurities, and problems such as gas turbine vibration, reduced efficiency, and accelerated component wear, seriously affecting the safe and stable operation of the unit.

[0004] Therefore, a gas turbine inlet temperature constant intake device has now been developed that can achieve constant temperature cooling, efficient dehumidification and impurity removal, and prevent filter element sludge buildup. Summary of the Invention

[0005] In order to overcome the shortcomings of existing technologies such as unstable gas turbine inlet temperature, high air humidity containing liquid water, easy sludge buildup and clogging of filter elements, and poor unit operation stability, this invention provides a gas turbine inlet temperature constant inlet device that can achieve constant temperature cooling, efficient dehumidification and impurity removal, and avoid filter element sludge buildup.

[0006] A gas turbine inlet temperature constant intake device includes an outer casing, mounting brackets detachable from the upper and lower sides of the outer casing by multiple bolts, a flow guiding component on the outer casing for guiding condensate, and a cooling component on the flow guiding component for reducing intake temperature and humidity and removing impurities.

[0007] To further explain, it also includes a temperature sensor located on the left side of the mounting bracket.

[0008] To further explain, the flow guiding assembly includes a fixed frame located inside the housing, a vent located on the upper left of the fixed frame, a drainage frame located on the lower right of the fixed frame, and a connecting hollow frame located on the lower left of the fixed frame. The drainage frame is connected to the connecting hollow frame.

[0009] To further explain, the mounting bracket is tilted downwards from left to right.

[0010] To further explain, the cooling component includes an inlet pipe located on the lower right side of the rear of the mounting frame, a temperature-regulating guide liquid plate located on the right side of the mounting frame, and an outlet pipe located on the lower right side of the front of the mounting frame. Both the inlet and outlet pipes are connected to the temperature-regulating guide liquid plate and are connected to the outer casing.

[0011] Further explanation: It also includes an interception assembly, which includes a first baffle plate located on the upper right side of the fixed frame, multiple second baffle plates located on the left side of the fixed frame, a third baffle plate located on the upper left side of the temperature regulating guide liquid plate, a connecting frame located on the left side of the fixed frame, and multiple fourth baffle plates located on the connecting frame. The vent is located above the first baffle plate, the connecting frame is located outside the second baffle plate, and the third baffle plate is located below the first baffle plate.

[0012] To further explain, the second and third baffles are staggered to form an S-shaped channel, which is used to effectively intercept water droplets carried in the air.

[0013] Further explanation: It also includes a water collection assembly, which includes multiple through holes opened at the bottom of the temperature-regulating guide liquid plate, a water channel opened at the bottom inner side of the connecting frame, a connecting pipe located at the lower right of the connecting frame, a water collection box located between the connecting frame and the outer shell, and a drain pipe located on the water collection box. The through holes are connected to the drain frame, the connecting pipe is connected to the water channel, the connecting pipe is connected to the water collection box, the connecting hollow frame is connected to the water collection box, and the drain pipe is connected to the outer shell.

[0014] To further explain, it also includes a triggering component, which includes an impeller rotatably located at the lower part of the inlet pipe and a triggering block located on the upper side of the impeller.

[0015] Further explanation: It also includes a drainage assembly, which includes a connecting pipe located on the right side of the drain pipe, a guide hollow frame slidably located on the upper side of the connecting pipe, two springs located between the guide hollow frame and the connecting pipe, a rotating column rotatably located on the upper side of the connecting pipe, and a connecting disc rotatably located inside the connecting pipe. The rotating column is triggered to press against the guide hollow frame. The rotating column has a spiral groove, and the guide hollow frame slides against the rotating column through the spiral groove. The rotating column is connected to the connecting disc.

[0016] The beneficial effects of this invention are as follows: 1. This invention circulates low-temperature cold water into the temperature-regulating guide liquid plate. After the air enters, it exchanges heat with the temperature-regulating guide liquid plate, thereby reducing the air temperature. Water vapor in the air condenses and precipitates onto the temperature-regulating guide liquid plate, and fine dust and particulate matter suspended in the air adheres to the precipitated droplets, thereby achieving cooling, dehumidification, and impurity removal of the outside air, avoiding the filter element from becoming damp, sludge-forming, and clogging, and ensuring the safe and stable operation of the gas turbine.

[0017] 2. In this invention, the cooled air flows upward through the gap between the first and third baffle plates, and then flows downward along the S-shaped channel formed between the second and third baffle plates. The droplets carried in the air collide with the first and third baffle plates, thereby further removing moisture from the air and ensuring the dehumidification effect.

[0018] 3. When the droplets attached to the temperature-regulating and guiding liquid plate of the present invention slide to the bottom, they flow into the drain rack through the through hole and merge with the droplets sliding down the fixed rack. The droplets gathered in the drain rack flow into the water collection box through the connecting hollow frame. The droplets dripping along the first and third baffle plates flow into the water collection box through the water channel and connecting pipe, and finally are discharged from the drain pipe. This can collect the precipitated water droplets, prevent the water droplets from vaporizing again, and ensure constant temperature and low humidity air intake.

[0019] 4. When cold water flows into the inlet pipe, the water flow drives the impeller to rotate, causing the trigger block to rotate and intermittently squeeze the guide hollow frame to move downward, causing the connecting pipe to open and close intermittently, thus discharging the water in the water collection box. This achieves air intake while automatically discharging the water in the water collection box, avoiding water accumulation and secondary vaporization to produce water mist, while also preventing air from escaping and ensuring sufficient air intake.

Detailed Implementation

[0030] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

[0031] A gas turbine inlet temperature constant intake device, such as... Figures 1-9 As shown, the system includes an outer casing 1, mounting brackets 2 that are detachable from the upper and lower sides of the outer casing 1 via multiple bolts, a flow guiding component on the outer casing 1 for guiding condensate, and a cooling component on the flow guiding component for reducing intake air temperature and humidity and removing impurities. In use, the outer casing 1 is installed between the gas turbine intake end and the ambient air supply equipment via the mounting brackets 2. Ambient air enters the outer casing 1 through the upper mounting bracket 2, where the cooling component lowers the air temperature and condenses moisture. The condensed moisture is then guided out through the flow guiding component. Dust and other impurities in the air adhere to the condensed droplets and are discharged with them. Finally, the cooled, dehumidified, and impurity-removed air enters the gas turbine intake end through the lower mounting bracket 2, thus ensuring the safe and stable operation of the gas turbine intake end. The mounting brackets 2 are detachable for easy cleaning of the interior of the outer casing 1.

[0032] To detect changes in air temperature, a temperature sensor 3 is also installed on the left side of the mounting bracket 2. The temperature sensor 3 is used to detect temperature changes before and after the air enters the housing 1, so as to facilitate timely adjustments.

[0033] The airflow guiding assembly includes a fixed frame 4 located inside the outer casing 1, a vent 41 located on the upper left side of the fixed frame 4, a drain frame 9 located on the lower right side of the fixed frame 4, and a connecting hollow frame 10 located on the lower left side of the fixed frame 4. The drain frame 9 is connected to the connecting hollow frame 10. The fixed frame 4 is inclined downwards from left to right to facilitate the drainage of condensate. After the cooling assembly cools and condenses the moisture in the air, the condensate drips onto the fixed frame 4, slides down the fixed frame 4 and is collected in the drain frame 9, and then is discharged through the connecting hollow frame 10 to avoid the accumulation of droplets. The cooled air continues to flow through the vent 41.

[0034] The cooling assembly includes an inlet pipe 5 located on the lower right side of the rear of the mounting frame 4, a temperature regulating guide liquid plate 6 located on the right side of the mounting frame 4, and an outlet pipe 7 located on the lower right side of the front of the mounting frame 4. Both the inlet pipe 5 and the outlet pipe 7 are connected to the temperature regulating guide liquid plate 6, and both the inlet pipe 5 and the outlet pipe 7 are connected to the outer shell 1. The inlet pipe 5 and outlet pipe 7 are connected to an external circulating refrigeration unit. Low-temperature chilled water is circulated into the temperature-regulating guide liquid plate 6 through the circulating refrigeration unit. After the air enters the outer shell 1, it exchanges heat with the temperature-regulating guide liquid plate 6 to reduce the air temperature. Water vapor in the air condenses and precipitates, adhering to the temperature-regulating guide liquid plate 6. Fine dust and particulate matter suspended in the air adhere to the precipitated droplets, thereby achieving cooling, dehumidification, and impurity removal of the outside air. This prevents the filter element from getting damp, sludge, and clogging, ensuring the safe and stable operation of the gas turbine. Most of the droplets adhering to the temperature-regulating guide liquid plate 6 drip down onto the fixed frame 4 and slide down and are discharged.

[0035] To further remove moisture from the air, an interception assembly is also provided on the fixed frame 4. The interception assembly includes a first baffle plate 40 on the upper right side of the fixed frame 4, thirteen second baffle plates 42 on the left side of the fixed frame 4, a third baffle plate 61 on the upper left side of the temperature-regulating guide liquid plate 6, a connecting frame 8 on the left side of the fixed frame 4, and fourteen fourth baffle plates 80 on the connecting frame 8. The vent 41 is located above the first baffle plate 40, the connecting frame 8 is located outside the second baffle plate 42, and the third baffle plate 61 is located below the first baffle plate 40. The second baffle plate 42 and the third baffle plate 61 are staggered to form an S-shaped channel to fully intercept water droplets carried in the air. The cooled air flows upward through the gap between the first baffle plate 40 and the third baffle plate 61. The droplets carried in the air hit the first baffle plate 40 and the third baffle plate 61, and then the droplets slide down along the fixed frame 4. The air enters the connecting frame 8 through the vent 41 and flows downward along the S-shaped channel formed between the second baffle plate 42 and the third baffle plate 61. The droplets carried in the air hit the first baffle plate 40 and the third baffle plate 61, and drip down along the first baffle plate 40 and the third baffle plate 61 to the bottom of the connecting frame 8, and then slide down along the connecting frame 8 and are discharged. This can further remove the moisture in the air and ensure the dehumidification effect. The air is discharged downward from the connecting frame 8.

[0036] To collect water droplets precipitated from the air, a water collection assembly is provided between the temperature-regulating guide liquid plate 6 and the connecting frame 8. The water collection assembly includes multiple through holes 60 opened at the lower part of the temperature-regulating guide liquid plate 6, a water channel 81 opened at the lower inner side of the connecting frame 8, a connecting pipe 82 located at the lower right part of the connecting frame 8, a water collection box 83 located between the connecting frame 8 and the outer shell 1, and a drain pipe 84 located on the water collection box 83. The through holes 60 are connected to the drain frame 9, the connecting pipe 82 is connected to the water channel 81, the connecting pipe 82 is connected to the water collection box 83, the connecting hollow frame 10 is connected to the water collection box 83, and the drain pipe 84 is connected to the outer shell 1. When the droplets attached to the temperature-regulating guide liquid plate 6 slide to the bottom, they flow into the drain rack 9 through the through hole 60 and merge with the droplets sliding down along the fixed frame 4. The droplets gathered in the drain rack 9 flow into the water collection box 83 through the connecting hollow frame 10. The droplets dripping along the first baffle plate 40 and the third baffle plate 61 flow into the water collection box 83 through the water channel 81 and the connecting pipe 82, and finally are discharged from the drain pipe 84. This allows for the collection of the precipitated water droplets, prevents secondary vaporization of the water droplets, and ensures constant temperature and low humidity air intake.

[0037] In order to automatically trigger the drainage of the water collection component, a triggering component is also provided on the liquid inlet pipe 5. The triggering component includes an impeller 50 that is rotatably located at the lower part of the liquid inlet pipe 5 and a triggering inclined block 51 located on the upper side of the impeller 50.

[0038] To drain the water from the water collection box 83, a drainage assembly is also provided on the drain pipe 84. The drainage assembly includes a connecting pipe 11 on the right side of the drain pipe 84, a guide hollow frame 12 slidably disposed on the upper side of the connecting pipe 11, two springs 120 on the left and right sides disposed between the guide hollow frame 12 and the connecting pipe 11, a rotating column 13 rotatably disposed on the upper side of the connecting pipe 11, and a connecting plate 14 rotatably disposed inside the connecting pipe 11. The inclined block 51 is triggered to press against the guide hollow frame 12. The rotating column 13 has a spiral groove, and the guide hollow frame 12 slides against the rotating column 13 through the spiral groove. The rotating column 13 is connected to the connecting plate 14. When cold water flows into the inlet pipe 5, the water flow drives the impeller 50 to rotate, causing the trigger block 51 to rotate. This intermittently squeezes the guide hollow frame 12 downwards, causing the spring 120 to contract under the pressure. Under the action of the spiral groove, the rotating column 13 rotates, driving the connecting plate 14 to rotate synchronously, opening the connecting pipe 11. The water collected in the water collection box 83 is discharged outwards through the drain pipe 84 and the connecting pipe 11. After the trigger block 51 moves away from the guide hollow frame 12, the spring 120 rebounds, driving the guide hollow frame 12 to move upwards and reset, causing the rotating column 13 and the connecting plate 14 to rotate and reset, closing the connecting pipe 11 and stopping the drainage. This allows the water in the water collection box 83 to be discharged intermittently, thus achieving automatic drainage of water from the water collection box 83 while simultaneously allowing air intake. This prevents water accumulation and secondary vaporization that could generate water mist, while also preventing air from escaping and ensuring sufficient air intake.
