[0016] (III) Beneficial Effects
[0017] Compared with the prior art, the present invention provides a compressor inlet cooling device, which has the following beneficial effects:
[0018] 1. Through the combined use of the atomizing nozzle and the first cooling water pipe, the gas enters the first housing. At this time, the first cooling water pipe will exchange heat with the gas to cool it down. At the same time, the atomizing nozzle will spray coolant to cool the gas down again. Then the gas enters the second housing for cooling down again, thereby reducing the intake temperature, increasing the compressor air mass flow rate, and improving the gas turbine power.
[0019] 2. The combined use of the Tongguo filter and air guide frame allows the filter to filter the air entering the housing, thereby reducing impurities in the air. At the same time, the air guide frame guides the air flow, causing the air to flow in a spiral shape within the housing, thereby increasing the contact area between the air and the heat dissipation pipes and improving the cooling effect of the air.
[0020] 3. Through the setting of the power component, the power component drives the distribution pipe to rotate, and the distribution pipe drives the atomizing nozzle to rotate. During the rotation process, the atomizing nozzle will swing under the action of the hemisphere and the torsion spring, thereby increasing the spray range of the atomizing nozzle and improving the use effect of the atomizing nozzle.
[0021] 4. Through the combined use of the connecting column and the sliding plate, when the gas enters the casing, the airflow will push the fan blades to rotate the connecting column. During the rotation of the connecting column, the centrifugal force will throw the sliding plate out of the groove. At this time, the sliding plate will turbulent the gas, so that the gas can better contact the heat dissipation pipe, further improving the cooling effect of the gas. Attached Figure Description

[0031] 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.
[0032] Example 1
[0033] Reference Figures 1-5A compressor inlet cooling device includes a first housing 1 and a second housing 2, both of which have openings at the top and bottom. The second housing 2 is located on top of the first housing 1. The first housing 1 and the second housing 2 are fixed together by a connecting assembly. A first cooling water pipe 5 is provided through both the first housing 1 and the second housing 2, and the first cooling water pipe 5 is bent into a cube. A fixing pipe 8 is bolted to the inner circumference of both the first housing 1 and the second housing 2. A liquid distribution pipe 7 is rotatably connected inside the fixing pipe 8. Multiple fixing rods 19 are welded to the bottom of the liquid distribution pipe 7. A rotating hole is opened on one side of each fixing rod 19, and a connecting shaft 20 is rotatably connected inside the rotating hole. An atomizing nozzle 22 is bolted between two adjacent connecting shafts 20. A torsion spring 23 is sleeved on the outside of the connecting shaft 20, and both ends of the torsion spring 23 are fixed to the fixing rod 19 and the connecting shaft 20, respectively. A corrugated pipe 21 is provided at the top of the atomizing nozzle 22. 21 is connected to the distribution pipe 7. A power assembly is provided on one side of both the first housing 1 and the second housing 2 to drive the distribution pipe 7 to rotate. Coolant is added to the first cooling water pipe 5, allowing it to flow within the pipe. Coolant is also added to the fixed pipe 8. Simultaneously, gas enters the first housing 1, contacting the first cooling water pipe 5. The coolant in the first cooling water pipe 5 exchanges heat with the gas, thus cooling it. Meanwhile, the coolant entering the fixed pipe 8 passes through the distribution pipe 7 into multiple corrugated pipes 21. The coolant is then atomized and sprayed out through the atomizing nozzle 22. The power assembly drives the distribution pipe 7 to rotate, which in turn drives the atomizing nozzle 22, further cooling the gas. The gas then enters the second housing 2 and is cooled again in the same manner, thus reducing the intake temperature, increasing the compressor air mass flow rate, and improving the gas turbine power.
[0034] In this invention, the power assembly includes two mounting plates 6, which are respectively bolted to the outer wall of one side of the first housing 1 and the second housing 2 above the fixing tube 8. A motor is bolted to the bottom of each mounting plate 6. One end of the motor output shaft passes through the mounting plate 6 and is bolted to a turntable 11. A connecting rod 12 is rotatably connected to the top of the turntable 11. A sliding opening is provided on one side of both the first housing 1 and the second housing 2, and a T-shaped rod 13 is slidably connected within the sliding opening. The T-shaped rod 13 is connected to the connecting rod 12. 2. Rotary connection: A guide groove 16 is provided at the top of the T-shaped rod 13. A fixing plate 15 is welded to one side of the fixing tube 8. A rotating opening is provided at the top of the fixing plate 15. A rotating frame 14 is rotatably connected inside the rotating opening. A fixing column 24 is welded to the top of the rotating frame 14. The fixing column 24 extends into the guide groove 16 and reciprocates along the guide groove 16. A gear is keyed to the bottom end of the rotating frame 14. Multiple evenly distributed tooth blocks 18 are welded to the inner ring of the liquid separator 7, and the tooth blocks 18 mesh with the gear. The first housing 1 and the second housing... Multiple hemispheres 9 are welded to the inner circumference of body 2, and the hemispheres 9 can contact the atomizing nozzle 22, causing the atomizing nozzle 22 to swing. When the motor is started, the motor drives the turntable 11 to rotate. The turntable 11 pulls the T-shaped rod 13 to move back and forth through the connecting rod 12. At the same time, the connecting rod 12 rotates with the T-shaped rod 13 and the turntable 11. During the movement of the T-shaped rod 13, the fixed column 24 moves back and forth in the guide groove 16, thereby causing the rotating frame 14 to drive the gear to rotate. The gear interacts with the tooth block 1 The engagement of 8 will drive the distributor 7 to rotate, which in turn will drive the atomizing nozzle 22 to rotate. During the rotation, the atomizing nozzle 22 will come into contact with the hemisphere 9. At this time, the protruding part of the hemisphere 9 will push the atomizing nozzle 22 to rotate through the connecting shaft 20 and cause the torsion spring 23 to generate torque. When the atomizing nozzle 22 rotates to the point where it disengages from the protruding part of the hemisphere 9, the atomizing nozzle 22 will reset under the force of the torsion spring 23. This cycle repeats, causing the atomizing nozzle 22 to swing and expand the spraying range of the atomizing nozzle 22.
[0035] In particular, a filter screen 3 is bolted to the top of the first housing 1 and the second housing 2, and a guide frame 10 is bolted to the bottom of the filter screen 3. When gas is added into the first housing 1, the filter screen 3 filters the gas entering the first housing 1, reducing impurities in the gas. At the same time, under the action of the guide frame 10, the gas will flow in a spiral shape in the first housing 1. The connecting components include flanges 4, which are welded to the top and bottom of the first housing 1 and the second housing 2. Two adjacent flanges 4 are bolted to fix the first housing 1 and the second housing 2. Mounting holes are opened on one side of the first housing 1 and the second housing 2. Water inlet pipes 17 are welded into the mounting holes and are connected to fixed pipes 8. Coolant is added to the fixed pipes 8 through the water inlet pipes 17.
[0036] Working principle: During use, coolant is added to the first radiator pipe 5, allowing it to flow within it. The coolant is then introduced into the fixed pipe 8 through the inlet pipe 17. Simultaneously, gas enters the first housing 1. The filter 3 filters the gas, reducing impurities. Under the action of the air guide 10, the gas flows in a spiral pattern within the first housing 1, contacting the first radiator pipe 5. The coolant in the first radiator pipe 5 exchanges heat with the gas, thus cooling it. Meanwhile, the coolant entering the fixed pipe 8 flows through the distributor pipe 7 into multiple corrugated pipes 21. The coolant is then atomized and sprayed out through the atomizing nozzle 22, providing secondary cooling. Simultaneously, the motor is started, driving the turntable 11 to rotate. The turntable 11, via the connecting rod 12, pulls the T-shaped rod 13, causing it to reciprocate. Rod 12 rotates between T-shaped rod 13 and turntable 11. During its movement, T-shaped rod 13 causes fixed column 24 to reciprocate within guide groove 16, thereby causing rotating frame 14 to drive gear to rotate. Gear meshing with tooth block 18 drives liquid distribution pipe 7 to rotate, which in turn drives atomizing nozzle 22 to rotate. During rotation, atomizing nozzle 22 contacts hemisphere 9. At this time, the protruding part of hemisphere 9 pushes atomizing nozzle 22 to rotate through connecting shaft 20 and causes torsion spring 23 to generate torque. When atomizing nozzle 22 rotates to disengage from the protruding part of hemisphere 9, atomizing nozzle 22 will reset under the force of torsion spring 23. This cycle repeats, causing atomizing nozzle 22 to swing, expanding the spray range of atomizing nozzle 22. Subsequently, the gas enters the second housing 2 and is cooled again in the above manner, thereby reducing the intake temperature, increasing the compressor air mass flow rate, and improving the gas turbine power.
[0037] Example 2
[0038] Reference Figures 6-8A compressor inlet cooling device further includes a second heat dissipation water pipe 25 and a connecting column 26. The second heat dissipation water pipe 25 is disposed inside a first housing 1 and a second housing 2, with both ends extending out of the first housing 1 and the second housing 2. The second heat dissipation water pipe 25 is arranged in a cylindrical shape that is wider in the middle and narrower at both ends. The connecting column 26 is rotatably connected to the bottom of the air guide frame 10 at its center position. Multiple fan blades 28 are welded to the outer side of the connecting column 26 at its bottom position. Multiple sliding grooves 27 are formed on the outer side of the connecting column 26, and sliding plates 30 are slidably connected in each of the multiple sliding grooves 27. Multiple tension springs 29 are welded to one side of the sliding plates 30, and the tension springs 29 are fixed to the connecting column 26. Limiting grooves 31 are formed at the top and bottom of the sliding grooves 27, and limiting blocks 32 are slidably connected in the limiting grooves 31. Furthermore, the limiting block 32 is fixed to the slide plate 30. When the gas flows in a spiral shape within the first housing 1, the cylindrical second heat dissipation pipe 25 matches the gas flow state, thus allowing the second heat dissipation pipe 25 to better exchange heat with the gas. Simultaneously, during the flow, the gas will push the fan blade 28 to rotate under the action of the airflow. During the rotation of the connecting column 26, under the action of centrifugal force, the slide plate 30 will be thrown out of the slide groove 27. The slide plate 30 will stretch the tension spring 29 and drive the limiting block 32 to move along the limiting groove 31, thereby limiting the length of the slide plate 30 that moves out of the slide groove 27. At this time, the ejected slide plate 30 will turbulent the gas, thus allowing the gas to better contact the second heat dissipation pipe 25, further improving the cooling effect on the gas.
[0039] The working principle of this embodiment is as follows: When the gas flows in a spiral shape inside the first housing 1, the cylindrical second heat dissipation water pipe 25 matches the gas flow state, thereby allowing the second heat dissipation water pipe 25 to better exchange heat with the gas. At the same time, during the flow, the gas will push the fan blade 28 to rotate the connecting column 26 under the action of airflow. During the rotation of the connecting column 26, the plate 30 will be thrown out of the slide groove 27 under the action of centrifugal force. The plate 30 will stretch the tension spring 29 and drive the limiting block 32 to move along the limiting groove 31, thereby limiting the length of the plate 30 that moves out of the slide groove 27. At this time, the thrown plate 30 will turbulent the gas, thereby allowing the gas to better contact the second heat dissipation water pipe 25, further improving the cooling effect on the gas.
