Technical Field

[0001] This utility model relates to the field of gas generator set technology, and in particular to an air and gas conditioning device for H-series gas generator sets. Background Technology

[0002] H-series gas generator sets are a type of high-efficiency, reliable gas generator set manufactured by certain gas generator manufacturers. These generator sets are mainly used in industrial and large power plants to provide efficient power output. The H-series places particular emphasis on gas turbine technology, gas supply management, and performance in terms of high efficiency and low emissions. The air-fuel conditioning system in H-series gas generator sets is typically used to regulate the air-fuel mixture ratio to ensure that the gas engine operates at optimal efficiency. The main function of this system is to control the supply of air and gas, making the combustion process both efficient and stable.

[0003] In some designs, the mixing of air and gas may not be uniform enough, especially in larger-scale gas turbines, which may lead to localized overheating or incomplete combustion. Therefore, it is necessary to propose an air-gas regulation device for H-series gas generator sets. Utility Model Content

[0020] Example

[0021] like Figures 1 to 3 As shown, the present invention proposes an air-fuel regulating device for an H-series gas generator set, comprising a mixing chamber 1, an air hole on the bottom surface of the mixing chamber 1, an exhaust pipe 17 at the corresponding position on the bottom surface of the mixing chamber 1, the exhaust pipe 17 being fixedly connected to the bottom surface of the mixing chamber 1, a valve 18 at the top of the exhaust pipe 17, the valve 18 controlling the emission of gas inside the mixing chamber 1, a motor 2 on the top surface of the mixing chamber 1, the top surface of the mixing chamber 1 being fixedly connected to the bottom surface of the motor 2, the output end of the motor 2 extending through into the interior of the mixing chamber 1 and having a stirring shaft 3, the output end of the motor 2 being rotatably connected to the top surface of the mixing chamber 1, the output end of the motor 2 being fixedly connected to the top of the stirring shaft 3, the bottom end of the stirring shaft 3 being rotatably connected to the interior bottom surface of the mixing chamber 1, facilitating the support and fixation of the stirring shaft 3, and a plurality of collars 4 on the outer ring of the stirring shaft 3, the outer ring of the stirring shaft 3 being fixedly connected to the inner ring of the collars 4;

[0022] Each collar 4 has multiple stirring rods 5 on its outer ring. The outer ring of collar 4 is fixedly connected to the stirring rods 5. The output end of motor 2 can drive the stirring shaft 3 to rotate. The rotation of the stirring shaft 3 can drive the collar 4 to rotate. The rotation of collar 4 can drive the stirring rods 5 to rotate. The rotation of the stirring rods 5 can stir the gas inside the mixing box 1, accelerating the mixing of the gas. The top of the stirring shaft 3 has a collar 6 on its outer ring. The outer ring of the stirring shaft 3 is fixedly connected to the inner ring of collar 6. The outer ring of collar 6 has two cleaning rods 7 on its outer ring. The outer ring of collar 6 is fixedly connected to the cleaning rods 7. The top surface of the mixing box 1 has two conveying pipes 8. The top surface of the mixing box 1 is fixedly connected to the conveying pipes 8. The top surface of the mixing box 1 has through holes corresponding to the position of each conveying pipe 8 to facilitate gas conveying. One conveying pipe 8 is connected to a gas source, and the other conveying pipe 8 is connected to an air source.

[0023] Each conveying pipe 8 has a filter plate 9 installed on its inner bottom ring. The filter plate 9 is fixedly installed inside the conveying pipe 8. The top surface of the cleaning rod 7 is in contact with the bottom surface of the filter plate 9. When the cleaning rod 7 rotates, it will continuously clean the bottom surface of the filter plate 9 to prevent the filter holes on the filter plate 9 from becoming clogged. Each conveying pipe 8 has a motor 10 installed at its top. The top of the conveying pipe 8 is fixedly connected to the mounting end of the motor 10. The output end of each motor 10 extends through into the interior of the conveying pipe 8 and is equipped with a baffle 11. The output end of motor 2 10 is rotatably connected to conveying pipe 8, and the output end of motor 2 10 is fixedly connected to baffle 11. The outer ring of baffle 11 fits against the inner wall of conveying pipe 8 to ensure sealing. When motor 2 10 is running, it can drive baffle 11 to rotate. The rotation of baffle 11 can convey gas. Both conveying pipes 8 are equipped with fixing ring 12 and vent plate 13. The fixing ring 12 and vent plate 13 are fixedly installed inside the conveying pipe 8. Multiple air passages are opened on the vent plate 13.

[0024] Each of the two venting plates 13 has a telescopic rod 14 on its opposite side. The venting plates 13 and the telescopic rods 14 are fixedly connected. Each telescopic rod 14 has a spring 15 on its outer ring. The telescopic rods 14 facilitate the guidance and limiting of the elastic recovery ability of the springs 15. Each of the two telescopic rods 14 has a plug 16 on its opposite side. The telescopic rods 14 and the plugs 16 are fixedly connected. The opposite side of the two plugs 16 abuts against the inner ring of one of the corresponding fixing rings 12, ensuring that the gas can flow normally while preventing the gas from flowing back.

[0025] In this embodiment, when using this device, if it is necessary to transport gas and air, motor 2 10 needs to be operated. The output end of motor 2 10 drives baffle 11 to rotate. Baffle 11 rotates inside the delivery pipe 8, thereby allowing gas to flow. When the internal gas pressure of the delivery pipe 8 increases, it will squeeze the plug 16 towards the side close to the vent plate 13, thereby causing the gas to flow from inside the fixed ring 12 to between the fixed ring 12 and the vent plate 13, and then flow through the air passage on the vent plate 13 to the bottom end of the delivery pipe 8. After being filtered by the filter plate 9, it is delivered to the mixing box 1. When gas enters the mixing chamber 1, motor 2 is activated. The output of motor 2 drives the stirring shaft 3 to rotate, which in turn drives the collar 4 and stirring rod 5 to rotate. The rotation of stirring rod 5 agitates the gas, thereby accelerating the mixing of the gas. At the same time, collar 6 and cleaning rod 7 rotate. The rotation of cleaning rod 7 cleans the bottom surface of filter plate 9, preventing blockage on filter plate 9 that would obstruct gas flow. After the gas is evenly mixed, it is discharged from exhaust pipe 17 to the combustion equipment through the control of valve 18.

[0026] The above-described specific embodiments are merely preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
