Description

Technical Field

[0001] This utility model relates to the field of gas supply system technology, and in particular to a gas-fired power generation gas supply system. Background Technology

[0002] Existing gas-fired power generation systems typically incorporate a filter and injection device in the intake pipe. After filtering the gas, the injection device sprays it through nozzles and spray nozzles to accelerate gas flow and prevent problems caused by excessively long pipes hindering gas entry into the generator. However, the cleaning device, located inside the pipe, is difficult to remove for cleaning, leading to filter blockage and impeding gas flow. For example, a gas generator supply system disclosed in Chinese Patent Application No. CN202021866586.7, while using an injection device in the intake pipe to accelerate gas entry into the cylinder and extend the generator's lifespan, cannot remove impurities adsorbed on the filter during use. Furthermore, the filter cannot be quickly removed for cleaning after use, resulting in long-term blockage due to accumulated impurities, thus affecting normal gas delivery and limiting its usability.

By installing a removable filter screen in the ventilation pipe, the filter screen can filter the gas before combustion, thereby improving the combustion efficiency of the gas. The motor drives a rotating rod and a cleaning brush to clean the filter screen, preventing the filter screen from being blocked during use and affecting the gas output. The swept-off impurities can fall into the interior of the threaded block. After use, the threaded block can be removed for quick cleaning of impurities, improving the cleaning efficiency. In addition, the exhaust pipe and connecting pipe are used to input the exhaust gas generated after combustion into the preheating pipe, and the residual heat in the exhaust gas is used to preheat the gas in the ventilation pipe, thereby improving the energy utilization efficiency and combustion efficiency.

[0023] Reference Figure 1-4This utility model provides a gas-fired power generation and gas supply system, which includes: a vent pipe 2, a threaded block 14 threadedly connected to the inner side wall of the vent pipe 2, a filter screen 17 fixedly connected to the upper surface of the threaded block 14, the side surface of the filter screen 17 being in contact with the vent pipe 2, a cover plate 1 fixedly connected to the lower surface of the threaded block 14, a motor 11 fixedly connected to the lower surface of the cover plate 1, a rotating rod 15 fixedly connected to the output end of the motor 11, a cleaning brush 16 fixedly connected to the side surface of the rotating rod 15, and the side surface of the cleaning brush 16 being rotatably connected to the filter screen 17.

[0024] Specifically, the filter screen 17 can be installed inside the vent pipe 2 via the threaded block 14 and the cover plate 1. When the gas enters the vent pipe 2 through the air inlet 3, the filter screen 17 will adsorb impurities such as particulate matter carried in the gas, and allow the filtered gas to pass through the regulating valve 4. The motor 11, which is fixed on the cover plate 1, will drive the rotating rod 15 to rotate, so that the rotating rod 15 can use the cleaning brush 16 to sweep off the impurities on the filter screen 17, so as to avoid the filter screen 17 from being blocked and affecting the normal supply of gas. The swept-off impurities will fall into and accumulate inside the threaded block 14. After use, the cover plate 1 can be rotated to remove the filter screen 17 and the threaded block 14 from the vent pipe 2, so as to facilitate the cleaning of the impurities inside the filter screen 17 and the threaded block 14.

[0025] The vent pipe 2 is fixedly connected to the preheating pipe 5 via the regulating valve 4. The inner side wall of the preheating pipe 5 is fixedly connected to the air guide pipe 18. The end of the air guide pipe 18 away from the preheating pipe 5 is fixedly connected to the nozzle 19. The end of the nozzle 19 away from the air guide pipe 18 is fixedly connected to the generator 8.

[0026] Specifically, the gas discharged from the vent pipe 2 will enter the gas guide pipe 18 inside the preheating pipe 5 through the regulating valve 4. During use, the flow rate of the gas entering the generator 8 can be adjusted by the regulating valve 4. The end of the gas guide pipe 18 is equipped with a nozzle 19, which can quickly spray the gas in the gas guide pipe 18, thereby accelerating the flow speed of the gas. The generator 8 is a gas generator that generates electricity by burning gas.

[0027] An exhaust port 6 is fixedly connected to the side surface of the preheating pipe 5, and an air inlet 7 is fixedly connected to the side surface of the preheating pipe 5. The end of the preheating pipe 5 away from the regulating valve 4 is fixedly connected to the generator 8. An exhaust pipe 10 is fixedly connected to the side surface of the generator 8. A connecting pipe 9 is fixedly connected to the side surface of the exhaust pipe 10. The end of the connecting pipe 9 away from the exhaust pipe 10 is fixedly connected to the air inlet 7. The upper surface of the cover plate 1 is in contact with the vent pipe 2. An air inlet 3 is fixedly connected to the end of the vent pipe 2 away from the cover plate 1.

[0028] Specifically, the exhaust gas produced after the gas is burned in the generator 8 will be discharged to the connecting pipe 9 through the exhaust pipe 10. Then, the connecting pipe 9 will guide the exhaust gas from the gas inlet 7 into the preheating pipe 5. The exhaust gas will flow along the inside of the preheating pipe 5 and finally be discharged from the exhaust port 6 to await further treatment. When the exhaust gas flows through the preheating pipe 5, it will come into contact with the gas guide pipe 18 and transfer the residual heat in the exhaust gas to the gas in the gas guide pipe 18 through the gas guide pipe 18, thereby achieving the effect of preheating the gas and improving the combustion efficiency of the gas.

[0029] A bushing 12 is fixedly connected to the inner side wall of the cover plate 1. The inner side of the bushing 12 is rotatably connected to the rotating rod 15. A sealing gasket 13 is fixedly connected to the side surface of the threaded block 14. The sealing gasket 13 is located between the cover plate 1 and the vent pipe 2.

[0030] Specifically, a bushing 12 is installed inside the cover plate 1 to protect the rotating rod 15. The bushing 12 enhances the sealing between the rotating rod 15 and the cover plate 1, so that gas and impurities will not be discharged from the vent pipe 2 through the connection between the rotating rod 15 and the cover plate 1 or affect the rotation of the rotating rod 15. A sealing gasket 13 is installed on the outside of the threaded block 14, so that the sealing gasket 13 can be fixed between the cover plate 1 and the vent pipe 2 after installation to prevent gas leakage.

[0031] Working principle: Before use, the cleaned filter screen 17 is installed in the vent pipe 2 via the threaded block 14. Then, the gas supply pipe is connected to the inlet 3. When the gas enters the vent pipe 2 through the inlet 3, the filter screen 17 adsorbs particulate matter and other impurities carried in the gas, allowing the filtered gas to pass through the regulating valve 4. The motor 11, fixed on the cover plate 1, drives the rotating rod 15 to rotate, so that the rotating rod 15 can use the cleaning brush 16 to sweep off the impurities on the filter screen 17. The swept impurities fall into and accumulate inside the threaded block 14. After use, the cover plate 1 can be rotated to remove the filter screen 17 and the threaded block 14 from the vent pipe 2. The gas is removed from the air pipe 2 to facilitate cleaning of impurities in the filter screen 17 and threaded block 14. The gas discharged from the air pipe 2 will enter the gas guide pipe 18 in the preheating pipe 5 through the regulating valve 4. During use, the flow rate of the gas entering the generator 8 can be adjusted by the regulating valve 4. The end of the gas guide pipe 18 is equipped with a nozzle 19 to quickly inject the gas in the gas guide pipe 18 into the generator 8 for combustion. The exhaust gas produced after combustion will be discharged from the exhaust pipe 10 and sent into the preheating pipe 5 through the connecting pipe 9 and the gas inlet 7. The residual heat in the exhaust gas is used to preheat the gas in the gas guide pipe 18, and finally discharged from the exhaust port 6.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
