Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of generator set, in particular to a gas turbine generator set. BACKGROUND

[0002] In modern society, the important role of electricity in people's production and life is self-evident. For example, in the field of oil and gas exploitation, it is necessary to use electric fracturing equipment for oil and gas exploitation. However, most of the fracturing well sites are located in sparsely populated areas, and the power grid is not well developed. In addition, the pressure operation is highly mobile. If the power grid is constructed solely for electric fracturing, the cost will be extremely high. Moreover, due to the frequent occurrence of natural disasters, the demand for emergency power supply is increasing. Therefore, in this case, in order to timely meet the power demand of production and life, a gas turbine generator set is needed to generate electricity to meet people's emergency power demand.

[0003] The gas turbine in the existing gas turbine generator set is mostly a single-shaft gas turbine. The single-shaft gas turbine compressor and the power turbine are the same shaft. The power output shaft of the gas turbine is connected with the compressor. However, due to the high speed of the compressor, the output speed of the power output shaft is high. Therefore, a gear box needs to be matched for speed reduction to meet the power generation demand. This design is complex, which is not conducive to quick installation and disassembly, resulting in the inability to meet the demand for timely power supply. CONTENT OF THE UTILITY MODEL

[0004] Therefore, the purpose of the present application is to provide a gas turbine generator set to solve the problem of the complex structure of the existing gas turbine generator set, which is not conducive to quick installation and disassembly, resulting in the inability to meet the demand for timely power supply.

[0005] According to one aspect of the present application, a gas turbine generator set is provided, comprising:

[0006] a cabin body;

[0007] a gas turbine and a generator, both of which are arranged in the cabin body. The gas turbine has an air inlet end and an air outlet end arranged opposite to each other in a horizontal direction. The gas turbine has at least two rotating shafts which can rotate independently. One of the rotating shafts is a power output shaft for outputting power. The power output shaft extends from the air inlet end.

[0008] The generator is arranged adjacent to the air inlet end in the horizontal direction and is connected to the power output shaft through a shaft coupling, so as to generate electricity under the drive of the gas turbine.

[0009] In one embodiment, the upper portion of the cabin body is provided with a gas turbine air inlet filtering system. The gas turbine is provided with an air inlet at the air inlet end. The gas turbine air inlet filtering system is connected to the air inlet through an air inlet volute. The shaft coupling is arranged in the air inlet volute.

[0010] In one embodiment, the inner cavity of the cabin includes a gas turbine cabin and a generator cabin, the gas turbine is arranged in the gas turbine cabin, and the generator is arranged in the generator cabin.

[0011] In one embodiment, the cabin is provided with a generator exhaust system above the cabin, and the generator exhaust system is connected to the inside of the generator cabin.

[0012] In one embodiment, the cabin is provided with a cabin ventilation system above the cabin, and the cabin ventilation system is connected to the inside of the gas turbine cabin.

[0013] In one embodiment, the gas turbine cabin is connected with a cabin exhaust system at one end away from the generator cabin, and the cabin exhaust system is connected to the inside of the gas turbine cabin.

[0014] In one embodiment, the gas turbine generator set further comprises a gas turbine exhaust silencer, the gas turbine exhaust silencer is arranged adjacent to the exhaust end in the horizontal direction, the exhaust end has an exhaust port, and the gas turbine exhaust silencer is connected to the exhaust port.

[0015] In one embodiment, the gas turbine generator set further comprises a vehicle, the cabin, the gas turbine and the generator are arranged on the vehicle, the vehicle has a head end and a tail end arranged opposite in the horizontal direction, and the exhaust end is located at the tail end.

[0016] In one embodiment, the bottom of the vehicle is provided with an axle, and the axle is connected to the vehicle by air suspension.

[0017] In one embodiment, the bottom of the vehicle is further provided with a lubrication system, and the lubrication system is connected to the gas turbine through a pipeline.

[0018] The gas turbine generator set has the following advantages. On the one hand, at least two rotatable shafts are arranged in the gas turbine, one of which is a power output shaft for outputting power (i.e., the gas turbine is a double-shaft gas turbine), so that the power output shaft can independently output power at a low speed, and thus the output speed of the gas turbine can directly meet the input speed requirement of the generator, without the need of connecting the generator through a gear reduction box. On the other hand, the power output shaft of the gas turbine extends from the air inlet end and is exposed outside the air inlet end, so that air for operating the gas turbine can enter the gas turbine from a position close to the power output shaft and the coupling. Since the temperature of the air entering the gas turbine is not high, the coupling does not need to consider the high-temperature effect when being designed. In addition, since the exhaust end is far away from the power output shaft and the coupling, the gas turbine does not need to be provided with an exhaust volute at the exhaust end to reduce the influence of high temperature on the coupling and the power output shaft. It can be seen that the above designs can reduce the design difficulty of the gas turbine generator set and the procurement cost of the parts, thereby facilitating rapid installation and disassembly, and further facilitating the timely power supply requirement of the gas turbine generator set.

[0030] The present application provides a gas turbine generator set for generating electricity in an emergency to provide emergency power supply to electrical equipment, so as to meet the power supply needs of people.

[0031] The structure of the gas turbine generator set provided by the present application will be described below with the gas turbine generator set used for providing emergency power supply to the electrically-driven fracturing equipment in the oil and gas exploration field as an example. The present embodiment is only used as an example for illustration and does not limit the technical scope of the present application. It can be understood that in other embodiments, the gas turbine generator set of the present application is not limited to only providing emergency power supply to the electrically-driven fracturing equipment in the oil and gas exploration field, but can also be used for providing emergency power supply to electrical equipment, which is not limited herein.

[0032] Referring to Figure 1 , Figure 1 The gas turbine generator set 10 provided by an embodiment of the present application is shown, the gas turbine generator set 10 provided by the embodiment of the present application includes a cabin body 100, a gas turbine 200 and a generator 300, wherein the gas turbine 200 and the generator 300 are both arranged in the cabin body 100, and the two are arranged adjacent to each other along a horizontal direction (the X direction shown in the figure, hereinafter referred to as the X direction), the generator 300 is connected to the gas turbine 200, and the generator 300 is driven by the gas turbine 200 to generate electricity, so as to be able to supply power to electrical equipment.

[0033] Specifically, the gas turbine 200 has a power output shaft 203 at one end close to the generator 300, the power output shaft 203 is connected with a power turbine, the generator 300 is connected to the power output shaft 203, the gas turbine 200 has a compressor and a combustion chamber, and the bottom of the cabin is provided with a fuel system 400 for providing fuel, the gas turbine 200 relies on the working medium (such as external air) input into its own interior to be compressed by the compressor, the compressed air ignites after mixing with the fuel in the combustion chamber, and high-temperature gas is generated to drive the turbine to rotate, thereby driving the power output shaft 203 to rotate, so as to drive the generator 300 to generate electricity.

[0034] In one embodiment, the cabin body 100 includes a gas turbine cabin 101 and a generator cabin 102 which are isolated from each other, the gas turbine 200 is arranged in the gas turbine cabin 101, and the generator 300 is arranged in the generator cabin 102, because the gas turbine 200 may have a problem of combustible gas leakage, by isolating the generator cabin 102 and the gas turbine cabin 101 from each other, it can be ensured that the possible leaked gas will not enter the generator cabin 102, so as to ensure the safety of the generator 300.

[0035] Further, as shown in Figure 1 some embodiments, the gas turbine generator set 10 further includes a gas turbine intake filter system 500, a cabin body ventilation system, a generator exhaust system 700, an electrical system 800 and a lubrication system 900. The lubrication system 900 is connected to the generator 300 and the gas turbine 200 through a pipeline; the gas turbine intake filter system 500, the cabin body ventilation system 600 and the generator exhaust system 700 are all arranged above the cabin body 100. Specifically, the generator exhaust system 700 is connected to the inside of the generator cabin 102 through a pipeline, the cabin body exhaust system is connected to the inside of the gas turbine cabin 101 through a pipeline, the gas turbine 200 has an intake end 201 and an exhaust end 202 which are oppositely arranged along the X direction, the intake end 201 is provided with an air inlet, the gas turbine intake filter system 500 is arranged above the cabin body 100 and connected to the air inlet through an intake volute 1000; the electrical system 800 is arranged beside the generator cabin 102.

[0036] The lubrication system 900 is used to provide lubricating oil for the generator 300 and the gas turbine 200; the cabin ventilation system 600 is used to provide ventilation for the engine cabin 101 to ensure that the problems in the engine cabin 101 meet the set requirements, and is also used to discharge the combustible gas in the engine cabin 101 to reduce the concentration of the combustible gas below the safety line; the generator exhaust system 700 is used to provide cold air for the generator cabin 102 to be able to cool the generator 300 and prevent the generator 300 from overheating; the engine intake filter system 500 is used to filter the dust and impurities in the external air before inputting the air into the gas turbine 200, so as to ensure that the air entering the gas turbine 200 is pure and uncontaminated, thereby ensuring the safe and reliable operation of the gas turbine 200; the intake volute 1000 is used to transport the air filtered by the engine intake filter system 500, so that the filtered air is more concentratedly input into the gas turbine 200; and the electrical system 800 is used to electrically control the gas turbine generator set 10, mainly including control and protection of the gas turbine 200 and the generator 300, and power supply and control of the auxiliary equipment such as the lubrication system 900, the engine intake filter system 500, the cabin ventilation system 600, the generator exhaust system 700, etc. Preferably, the electrical system 800 is covered in a protective shell to avoid rain, snow and other weather from entering the electrical system 800, and the protective shell can also provide heat preservation and sound insulation.

[0037] Further, in order to provide the flexibility of emergency power generation, the gas turbine generator set 10 further comprises a carrier vehicle 1100, and the cabin 100, the gas turbine 200, the generator 300, the engine intake filter system 500, the cabin ventilation system 600, the generator exhaust system 700, the electrical system 800 and the lubrication system 900 are all arranged on the carrier vehicle 1100, so that the carrier vehicle 1100 is used to facilitate the transportation of the gas turbine 200 and the generator 300. For example, in the embodiment shown in the figure, the gas turbine generator set 10 is a vehicle-mounted gas turbine generator set 10, and the carrier vehicle 1100 is a semi-trailer chassis vehicle, which can also be various transportation tools such as a second-class chassis vehicle, without limitation.

[0038] Preferably, referring to Figure 2 , the bottom of the carrier vehicle 1100 is provided with an axle, for example, the axle can include a fixed axle 1110, and in order to facilitate the steering of the carrier vehicle 1100, the axle can also include a follow-up steering axle 1120; the axle is connected to the carrier vehicle 1100 through air suspension, so that the vibration caused by the uneven road surface during transportation can be reduced to the greatest extent to reduce the damage to the gas turbine 200, the generator 300 and other equipment.

[0039] Therefore, by integrating the above-mentioned devices on the vehicle 1100, the devices do not need to be installed and disassembled on site, so the transportation is convenient. When used on site, the gas turbine 200 is only connected to the fuel system 400, and the generator 300 can be used to generate electricity to power the electric fracturing equipment and other electric equipment, so that the equipment deployment is convenient, especially in the current trend of oil-to-electricity in the oil field, it can meet the needs of rapid installation and power supply in the industry.

[0040] More preferably, the gas turbine generator set 10 provided by the present application further comprises a cabin exhaust system 1200, wherein the cabin exhaust system 1200 is communicated with the inside of the gas turbine cabin 101, and is used to introduce the cabin ventilation system 600 into the cold air exhaust cabin 100 in the gas turbine cabin 101, and can also reduce the noise generated by the airflow; optionally, the gas turbine generator set 10 further comprises a gas turbine exhaust silencer 1300, which is arranged adjacent to the exhaust end 202 of the gas turbine 200 in the horizontal direction. The exhaust end 202 has an exhaust hole, and the gas turbine exhaust silencer 1300 is connected to the exhaust port, so that the exhaust gas discharged by the gas turbine 200 can be reduced in noise before being discharged into the atmosphere.

[0041] It can be understood that the above-mentioned devices can be selectively provided with one or any of them as needed, and can be selected according to actual conditions, which is not limited here.

[0042] However, it should be noted that for the above-mentioned embodiments, as described in the background, the gas turbine 200 in the existing gas turbine generator set 10 is mostly a single-shaft gas turbine, and the compressor and the power turbine in the single-shaft gas turbine are connected through the same shaft (i.e. the power output shaft 203). Therefore, the power output shaft 203 is connected to the compressor. Since the speed of the compressor is high, the output speed of the power output shaft 203 is also high. At this time, a gear reduction box needs to be installed between the power output shaft 203 and the generator 300 to reduce the speed of the power output shaft 203, so as to meet the power generation demand. This design is complex, which is not conducive to rapid installation and disassembly, and cannot meet the demand of timely power supply.

[0043] To this end, considering that the existing gas turbine 200 is also a double-shaft or multi-shaft gas turbine, in an improved embodiment, the applicant conceives to replace the single-shaft gas turbine 200 with a double-shaft or multi-shaft gas turbine to solve the above problems. Specifically, the double-shaft gas turbine 200 has two independent rotating shafts, and the two rotating shafts are not directly mechanically connected. One of the rotating shafts is connected to the compressor, and the other rotating shaft is connected to the power turbine as the power output shaft 203. The two rotating shafts can rotate independently at different speeds, so that the power output shaft 203 can independently output power at a lower speed, and thus the output speed of the gas turbine 200 can directly meet the input speed requirement of the generator, without the need to install a speed reduction gearbox. The gas turbine generator set 10 can be directly connected to the generator 300 through the shaft coupling 1400, thereby simplifying the design of the gas turbine generator set 10.

[0044] By analogy, it is not difficult to understand that for a multi-shaft gas turbine, it has multiple rotating shafts that can move independently. Each adjacent two rotating shafts are not directly mechanically connected, and the multiple rotating shafts can form multiple stages of compression ratio, thereby improving the power of the gas turbine 200. One of the rotating shafts is the power output shaft 203, and the details are not described in detail.

[0045] Further, it is also worth noting that although the double-shaft or multi-shaft gas turbine 200 does not need to install a gear reduction box to reduce the speed of the power output shaft 203, the common double-shaft or multi-shaft gas turbine power output shaft 203 is exposed from the exhaust end 202 and exposed to the exhaust end 202. Therefore, the shaft coupling 1400 is also located at the exhaust end 202. Thus, some problems still exist. Specifically, because the exhaust gas temperature of the gas turbine 200 is too high, an exhaust volute needs to be installed at the exhaust end 202 to separately isolate the shaft coupling 1400 and the power output shaft 203, thereby reducing the contact of the shaft coupling 1400 and the power output shaft 203 with the high-temperature hot gas. However, when installing the exhaust volute, the exhaust back pressure and flow field factors need to be considered, and the design of the exhaust volute also needs to be considered, for example, the opening direction of the exhaust volute can only be perpendicular to the X direction, thus causing the gas turbine exhaust silencer 1300 to be installed only on the top or both sides of the entire gas turbine generator set 10. If the gas turbine exhaust silencer 1300 is installed on the top of the entire machine, the height of the entire machine will exceed the regulation requirements of the semi-trailer and cannot be transported. If the gas turbine exhaust silencer 1300 is installed on both sides of the entire machine, the width of the entire machine will also exceed the regulation requirements of the semi-trailer and cannot be transported. Therefore, the gas turbine exhaust silencer 1300 cannot be integrated with the vehicle 1100, and needs to be transported by another vehicle, and then installed on site using a crane. This greatly increases the labor and material costs and increases the installation difficulty.

[0046] In addition, in the design structure, the exhaust volute is also located between the gas turbine 200 and the generator 300. Since the exhaust gas discharged by the gas turbine 200 is too high in temperature, the surface of the exhaust volute is also very high in temperature, and therefore the exhaust volute needs to be made of high-temperature-resistant material, and the thermal expansion design of the exhaust volute needs to be fully considered. In order to avoid the influence of the high temperature of the exhaust volute on other instruments and apparatuses in the engine cabin 101, the exhaust volute also needs to be designed to be heat-insulated. Even if the exhaust volute is designed to be heat-insulated, the exhaust volute still greatly affects the temperature of the cabin body 100. In order to reduce the temperature of the cabin body 100, the ventilation volume of the engine cabin 101 also needs to be increased to reduce the temperature of the cabin body 100. The above factors all lead to the fact that the structure of the gas turbine generator set 10 is also complex, the development difficulty is also great, and the requirement of rapid installation and disassembly to ensure timely power supply cannot be met.

[0047] In order to solve the series of problems mentioned above, the applicant of the present application thinks of reforming the structure of the aero-gas machine of the aircraft propulsion device, so as to reform the gas turbine 200 in the gas turbine generator set 10. Specifically, the aero-gas machine is also a double-shaft or multi-shaft gas turbine in essence. However, the head of the aero-gas machine 200 is provided with a propeller, and the head has an air inlet. The propeller is installed at the position of the air inlet. The tail has a tail nozzle. The outside air enters the compressor in the aero-gas machine from the head where the propeller is installed. The compressed air is mixed with fuel in the combustion chamber and ignited to generate high-temperature gas. The high-temperature gas drives the turbine to rotate. The turbine transmits power to the propeller through the transmission shaft, so as to generate thrust. The high-temperature gas generated after combustion is discharged from the tail nozzle of the tail, to generate reaction force to drive the aircraft to move forward.

[0048] Based on the above structure, when reforming, the propeller can be removed, and the transmission shaft connected to the propeller is directly connected with the coupling 1400 as the power output shaft 203. In this way, the gas turbine 200 in the gas turbine generator set 10 provided by the present application is not only a double-shaft or multi-shaft gas turbine, but also does not need to be connected with the generator 300 through the gear reduction box. In addition, as shown in Figure 3 The power output shaft 203 extends from the air inlet end 201 and is exposed outside the air inlet end 201.

[0049] In this way, as shown in Figure 1As shown, after the above modification, the air used to operate the gas turbine 200 can enter the inside of the gas turbine 200 from a position close to the power output shaft 203 and the coupling 1400. Since the temperature of the air entering the gas turbine 200 is not high, the air inlet volute 1000 does not need to be designed to consider heat insulation, and the coupling 1400 does not need to be designed to consider high temperature effects. At the same time, since the exhaust end 202 is away from the power output shaft 203 and the coupling 1400, the high-temperature exhaust gas can be discharged from the end away from the power output shaft 203 and the coupling 1400, so there is no need to install an exhaust volute on the exhaust end 202 of the gas turbine 200 to reduce the effects of high temperature on the coupling 1400 and the power output shaft 203.

[0050] Further, referring again to Figure 2 , the vehicle 1100 has a leading end 1101 and a trailing end 1102 arranged opposite along the X direction. After the above modification, the exhaust end 202 of the gas turbine 200 is located at the trailing end 1102 of the vehicle 1100, and the gas turbine exhaust silencer 1300 can also be arranged at the trailing end of the vehicle 1100 along the X direction, so that the gas turbine exhaust silencer 1300 can also be integrated on the vehicle 1100, without the need for other vehicles for transportation, and without the need for on-site lifting, so that the above-mentioned series of problems do not exist, thereby reducing the design difficulty and procurement cost. Under the general trend of oil-to-electricity in the oil field, it also better meets the current industry's demand for rapid installation and power supply.

[0051] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not contradict, they should be considered within the scope of the present disclosure.

[0052] The above-described embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it should not be understood as limiting the scope of the patent application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of the present application. Therefore, the scope of the patent of the present application should be subject to the appended claims.
