At this time, the coolant in the first heat dissipation water pipe 5 will exchange heat with the heat in the gas, thereby cooling the gas. At the same time, the coolant entering the fixed pipe 8 will enter the multiple bellows 21 through the liquid dispensing pipe 7, and then the coolant is atomized and sprayed out through the atomizing nozzle 22, and the liquid dispensing pipe 7 is driven to rotate by the power component, and the liquid dispensing pipe 7 drives the atomizing nozzle 22 to rotate, thereby cooling the gas for the second time, and then the gas enters the second shell 2 and is cooled again in the above manner, so as to reduce the intake temperature, increase the air mass flow of the compressor, and improve the power of the gas turbine.

[0034] In the present invention, the power assembly includes two mounting plates 6, which are respectively fixed to the outer wall of one side of the first housing 1 and the second housing 2 by bolts at a position above the fixed tube 8, and the bottom of the two mounting plates 6 are fixed with motors by bolts, and one end of the motor output shaft passes through the mounting plate 6 and is fixed with a turntable 11 by bolts, and the top of the turntable 11 is rotatably connected with a connecting rod 12, and a sliding opening is opened on one side of the first housing 1 and the second housing 2, and a T-shaped rod 13 is slidably connected in the sliding opening, and the T-shaped rod 13 and the connecting rod 12 are connected to each other. 2 is rotatably connected, a guide groove 16 is provided on the top of the T-shaped rod 13, a fixing plate 15 is welded on one side of the fixing tube 8, a turning opening is provided on the top of the fixing plate 15, a rotating frame 14 is rotatably connected in the turning opening, a fixing column 24 is welded on 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 key-connected at the bottom end of the rotating frame 14, a plurality of evenly distributed tooth blocks 18 are welded on the inner ring of the dispensing tube 7, and the tooth blocks 18 are meshed with the gears, the first shell 1 and the second shell The inner wall of the body 2 is welded with a plurality of hemispheres 9, and the hemispheres 9 can contact the atomizing nozzle 22 to make the atomizing nozzle 22 swing.

The meshing of 8 will drive the liquid dispensing tube 7 to rotate, and the liquid dispensing tube 7 will drive the atomizing nozzle 22 to rotate. The atomizing nozzle 22 will contact the hemisphere 9 during the rotation. At this time, the raised part of the hemisphere 9 will push the atomizing nozzle 22 to rotate through the connecting shaft 20 and make the torsion spring 23 generate a torsion force.

[0035] In particular, a filter screen 3 is fixed at the top position of the first shell 1 and the second shell 2 by bolts, and an air guide frame 10 is fixed to the bottom of the filter screen 3 by bolts. When gas is added to the first shell 1, the filter screen 3 will filter the gas entering the first shell 1 to reduce impurities in the gas. At the same time, under the action of the air guide frame 10, the gas will flow in the first shell 1 in a spiral shape.

The water inlet pipe 17 is connected to the fixed pipe 8, and the coolant is added to the fixed pipe 8 through the water inlet pipe 17.

[0036] Working principle: when in use, add the coolant into the first heat dissipation water pipe 5, make the coolant flow in the first heat dissipation water pipe 5, and add the coolant into the fixed pipe 8 through the water inlet pipe 17, and at the same time, the gas enters the first shell 1. At this time, the filter 3 will filter the gas entering the first shell 1 to reduce impurities in the gas. At the same time, under the action of the air guide frame 10, the gas will flow in the first shell 1 in a spiral shape, so that the gas contacts the first heat dissipation water pipe 5. At this time, the coolant in the first heat dissipation water pipe 5 will perform heat exchange with the heat in the gas, thereby cooling the gas. At the same time, the coolant entering the fixed pipe 8 will enter the multiple bellows 21 through the liquid distribution pipe 7, and then the coolant will be atomized and sprayed out through the atomizing nozzle 22, thereby cooling the gas for the second time. At the same time, the motor is started, the motor will drive the turntable 11 to rotate, and the turntable 11 will pull the T-bar 13 to reciprocate through the connecting rod 12, and at the same time, the connecting rod 12 will pull the T-bar 13 to reciprocate. The rod 12 will rotate with the T-bar 13 and the turntable 11, and the T-bar 13 will make the fixed column 24 reciprocate in the guide groove 16 during the movement, so that the rotating frame 14 drives the gear to rotate, and the gear will drive the liquid dispensing tube 7 to rotate by meshing with the tooth block 18, and the liquid dispensing tube 7 will drive the atomizing nozzle 22 to rotate. The atomizing nozzle 22 will contact the hemisphere 9 during the rotation. At this time, the raised 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 disengage from the raised part of the hemisphere 9, the atomizing nozzle 22 will reset under the action of the torsion spring 23, and the cycle will be repeated, so that the atomizing nozzle 22 swings, and the spraying range of the atomizing nozzle 22 is expanded. Then the gas enters the second shell 2 and is cooled again in the above manner, so as to reduce the intake temperature, increase the air mass flow of the compressor, and improve the power of the gas turbine.

[0037] Example 2

[0038] Reference Figure 6-Figure 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 arranged in the first shell 1 and the second shell 2. Both ends of the second heat dissipation water pipe 25 extend out of the first shell 1 and the second shell 2. The second heat dissipation water pipe 25 surrounds to form a cylindrical shape that is wide in the middle and narrow at both ends. The connecting column 26 is rotatably connected to the bottom of the air guide frame 10 at a central position. A plurality of fan blade plates 28 are welded to the outer side of the connecting column 26 at a bottom position. A plurality of slide grooves 27 are provided on the outer side of the connecting column 26. Slide plates 30 are slidably connected in the plurality of slide grooves 27. A plurality of tension springs 29 are welded on one side of the slide plate 30, and the tension spring 29 is fixed to the connecting column 26. A limiting groove 31 is provided at the top and bottom of the slide groove 27. A limiting block 32 is slidably connected in the limiting groove 31. The limit block 32 is fixed to the slide plate 30. When the gas flows in the first shell 1 in a spiral shape, the cylindrical second heat dissipation water pipe 25 is consistent with the state of the gas flow, so that the second heat dissipation water pipe 25 can better exchange heat with the gas. At the same time, during the flow of the gas, the fan blade plate 28 will be pushed by the action of the airflow to drive the connecting column 26 to rotate. During the rotation of the connecting column 26, the slide plate 30 will be thrown out of the slide groove 27 under the action of centrifugal force. The slide plate 30 will stretch the tension spring 29 and drive the limit block 32 to move along the limit groove 31, thereby limiting the length of the slide plate 30 moving out of the slide groove 27. At this time, the thrown-out slide plate 30 will disturb the gas, so that the gas can better contact with the second heat dissipation water pipe 25, further improving the cooling effect on the gas.

[0039] The working principle of this embodiment is as follows: when in use, when the gas flows in a spiral shape in the first shell 1, the cylindrical second heat dissipation water pipe 25 is consistent with the state of the gas flow, so that the second heat dissipation water pipe 25 can better exchange heat with the gas. At the same time, during the flow of the gas, the fan blade plate 28 will be pushed by the action of the airflow to drive the connecting column 26 to rotate. During the rotation of the connecting column 26, the slide plate 30 will be thrown out of the slide groove 27 under the action of centrifugal force. The slide plate 30 will stretch the tension spring 29 and drive the limit block 32 to move along the limit groove 31, thereby limiting the length of the slide plate 30 moving out of the slide groove 27. At this time, the thrown-out slide plate 30 will disturb the gas, so that the gas can better contact with the second heat dissipation water pipe 25, further improving the cooling effect on the gas.
