Description

Technical Field

[0001] The present application belongs to the technical field of power generation equipment, and specifically relates to a lubrication system for a gas turbine generator set and a gas turbine generator set. Background Art

[0002] With the continued development of the global economy and the increasing demand for energy, the market demand for industrial gas turbines is also showing a rapid growth trend. In the industrial production sector, industrial gas turbines have become the power equipment of choice for many companies due to their efficient, stable, and reliable power output. Industrial gas turbines are widely used in industrial production, oil and gas, and aviation due to their high efficiency and reliability, and market demand is gradually increasing.

[0003] During the operation of some gas turbine generators in related technologies, the temperature of the lubricating oil is high due to poor heat dissipation of the lubricating oil, which affects the properties of the lubricating oil and is detrimental to the lubrication effect of the gas turbine generator set. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide a lubrication system for a gas turbine generator set and a gas turbine generator set, which can solve problems such as poor heat dissipation effect of lubricating oil.

[0005] In order to solve the above technical problems, this application is implemented as follows:

[0006] An embodiment of the present application provides a lubrication system for a gas turbine generator set, wherein the gas turbine generator set includes a gas turbine and a generator connected in a transmission manner, and a vehicle body for carrying the gas turbine and the generator, wherein the vehicle body has a gooseneck;

[0007] The lubrication system includes a lubrication path and a second heat dissipation assembly. The lubrication path is used to supply lubricating oil to the gas turbine and the generator. The second heat dissipation assembly includes a second radiator. The second radiator is used to be arranged at the gooseneck, and the second radiator is connected to the lubrication path to dissipate heat of the lubricating oil supplied by the lubrication path through the second radiator.

[0008] The embodiment of the present application further provides a gas turbine generator set, comprising the above-mentioned lubrication system, wherein the vehicle body comprises a main vehicle body and an auxiliary vehicle body, the gas turbine and the generator are both provided on the main vehicle body, and the auxiliary vehicle body is provided with the gooseneck;

[0024] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0026] The embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0027] refer to Figures 1 to 7 The present embodiment discloses a lubrication system 04 for a gas turbine generator set. The gas turbine generator set includes a gas turbine 01 and a generator 02 connected by a transmission mechanism. For example, the gas turbine 01 and the generator 02 may be connected by a gearbox 03 to ensure smooth transmission. The gas turbine generator set also includes a vehicle body for supporting the gas turbine 01 and the generator 02. This ensures stable support for the gas turbine 01 and the generator 02 and facilitates their transportation.

[0028] Lubrication system 04 may include a lubrication path 10. Components such as gas turbine 01 and generator 02 may be connected to lubrication path 10 to supply lubricating oil to at least gas turbine 01 and generator 02 via lubrication path 10, thereby lubricating these components. Gearbox 03 may also be connected to lubrication path 10 to lubricate gearbox 03.

[0029] Alternatively, as Figure 1As shown, the lubrication path 10 may include an oil tank 11, an oil pump 12, a lubricating oil circuit 13, etc. The gas turbine 01, the generator 02, etc. may all be connected to the lubricating oil circuit 13. In this way, under the action of the oil pump 12, the lubricant in the oil tank 11 may be respectively transported to the gas turbine 01, the generator 02, etc. through the lubricating oil circuit 13 to achieve the lubrication effect on the gas turbine 01 and the generator 02.

[0030] Taking into account that components such as the gas turbine 01 and the generator 02 can generate heat respectively during operation, and the lubricating oil will absorb part of the heat when passing through the gas turbine 01 and the generator 02, the lubricating oil can be used to cool the gas turbine 01 and the generator 02. At the same time, the temperature of the lubricating oil that absorbs heat is increased.

[0031] In order to dissipate heat of the lubricating oil, the lubrication system 04 may further include a second heat dissipation component 30, which includes a second radiator 31, so that the lubricating oil transmitted by the lubrication path 10 can enter the second radiator 31. In this way, the heat in the lubricating oil can be dissipated through the second radiator 31 to reduce the temperature of the lubricating oil, so that the cooled lubricating oil can continue to lubricate and cool components such as the gas turbine 01 and the generator 02.

[0032] Optionally, the second radiator 31 may be connected to the lubricating oil passage 13 so that lubricating oil is delivered to the second radiator 31 through the lubricating oil passage 13 .

[0033] Furthermore, the vehicle body may include a gooseneck 062, with a second radiator 31 disposed thereon. The second radiator 31 is in communication with the lubrication path 10, allowing the lubricating oil supplied by the lubrication path 10 to be dissipated through the second radiator 31. It should be noted that the gooseneck 062 can serve as a connection between the vehicle bodies and also support certain components, such as the second radiator 31, by being disposed on the gooseneck 062. For example, the longitudinal cross-section of the gooseneck 062 may be Z-shaped.

[0034] Based on the above-mentioned configuration, in the embodiment of the present application, the gas turbine 01 and the generator 02 can be lubricated and cooled through the lubrication path 10 to ensure that the gas turbine 01 and the generator 02 can operate normally. Since the lubricating oil absorbs heat when passing through the gas turbine 01 and the generator 02, causing the temperature to rise, the lubrication path 10 transports the heated lubricating oil to the second heat dissipation component 30, and then the heat can be dissipated to the outside through the second heat dissipation component 30; further, the second heat dissipation component 30 is arranged at the gooseneck 062 of the vehicle body, so that the second heat dissipation component 30 is arranged in the open air, thereby improving the heat dissipation efficiency of the second heat dissipation component 30, and thus effectively preventing the lubricating oil temperature from being too high and affecting the cooling effect on the gas turbine 01 and the generator 02.

[0035] refer to Figure 7 In some embodiments, the second heat dissipation assembly 30 may include multiple second radiators 31 arranged at intervals along the left-right direction of the vehicle body at the gooseneck 062 . Based on this arrangement, heat-absorbing lubricating oil can be transported via the lubrication path 10 to the multiple second radiators 31 for dissipation. Furthermore, since the multiple second radiators 31 are all located at the gooseneck 062 of the vehicle body, they are all exposed to the open air, which improves heat dissipation efficiency to a certain extent and prevents excessive lubricating oil temperature from affecting the heat dissipation of components such as the gas turbine 01 and the generator 02 .

[0036] For example, multiple second radiators 31 are arranged at intervals on the gooseneck 062 along the left and right directions of the vehicle body, which can help to fully utilize the space at the gooseneck 062 and does not occupy the space in the front and rear directions of the vehicle body, which can help to shorten the length direction of the vehicle body to a certain extent.

[0037] In some more specific embodiments, the second heat dissipation assembly 30 may include two second heat sinks 31 , and the two second heat sinks 31 are symmetrically arranged on the gooseneck 062 .

[0038] refer to Figure 1 and Figure 7 In some embodiments, the lubrication system 04 may further include a duplex filter 40, which is connected to the lubrication path 10 to filter the lubricating oil. Furthermore, the lubrication system 04 may further include a lubricating oil differential pressure sensor and a detection circuit. One end of the detection circuit is connected to an area of ​​the lubrication path 10 upstream of the duplex filter 40, and the other end of the detection circuit is connected to an area of ​​the lubrication path 10 downstream of the duplex filter 40. The lubricating oil differential pressure sensor is disposed within the detection circuit. Based on this, the lubricating oil differential pressure sensor can detect the lubricating oil pressure differential at both ends of the duplex filter 40 in real time, thereby determining whether the duplex filter 40 is clogged.

[0039] Optionally, the duplex filter 40 may be connected to the lubricating oil circuit 13 , so that the duplex filter 40 filters the lubricating oil in the lubricating oil circuit 13 .

[0040] Based on the above settings, the lubricating oil differential pressure sensor can detect the pressure difference at both ends of the double filter 40 in real time. When the double filter 40 is in normal conditions, the pressure difference between the upstream area and the downstream area of ​​the double filter 40 detected by the lubricating oil differential pressure sensor does not exceed the preset pressure difference; when the detected pressure difference exceeds the preset pressure difference, it indicates that the double filter 40 is clogged, faulty, etc., which can serve as a reminder for the staff to ensure the normal operation of the lubrication system 04.

[0041] In addition, the duplex filter 40 can be arranged at the gooseneck 062 , so that the duplex filter 40 can be located around the second radiator 31 . This arrangement can more fully utilize the space at the gooseneck 062 .

[0042] Continue to refer Figure 7 In some embodiments, a guardrail 063 may be provided at the gooseneck 062, and the guardrail 063 is arranged around the periphery of the second radiator 31. In this way, the guardrail 063 can provide a certain degree of protection for the second radiator 31 to prevent the second radiator 31 from being damaged. In addition, when the staff is working on the gooseneck 062, the guardrail 063 can also provide protection for the personnel to prevent them from falling from the gooseneck 062 and causing injuries.

[0043] Furthermore, a ladder 064 may be provided at the gooseneck 062 , and the ladder 064 is used for workers to go up and down the gooseneck 062 , thereby facilitating the maintenance of the components on the gooseneck 062 by the workers.

[0044] Based on the above lubrication system 04, the embodiment of the present application further discloses a gas turbine generator set, and the disclosed gas turbine generator set includes the above lubrication system 04. The vehicle body may include a main vehicle body 05 and an auxiliary vehicle body 06, such as Figure 2 As shown, both the gas turbine 01 and the generator 02 can be mounted on the main vehicle body 05, ensuring stable support for the gas turbine 01 and the generator 02. The auxiliary vehicle body 06 can be used to carry other accessories, such as cooling components and fans. Based on this configuration, the embodiment of the present application adopts a dual-vehicle load-bearing method using the main vehicle body 05 and the auxiliary vehicle body 06. Compared to a single-vehicle load-bearing method, the embodiment of the present application can reduce the load per vehicle, thereby alleviating the problem of excessive vehicle axle load, and effectively reducing the vehicle width to meet road transport regulations.

[0045] The auxiliary vehicle body 06 may be provided with a gooseneck 062, and at least a portion of the lubrication system 04 may be disposed on the auxiliary vehicle body 06, with the second heat dissipation assembly 30 disposed at the gooseneck 062. Based on this arrangement, the gooseneck 062 of the auxiliary vehicle body 06 can support the second heat dissipation assembly 30, thereby reducing the load on the main vehicle body 05 and facilitating heat dissipation from the second heat dissipation assembly 30, thereby improving heat dissipation efficiency.

[0046] In order to dissipate heat of the lubricating oil, the lubrication system 04 may further include a first heat dissipation component 20, which includes a first radiator 21. The first radiator 21 is connected to the lubrication path 10, so that the lubricating oil transmitted by the lubrication path 10 can enter the first radiator 21, so that the lubricating oil supplied by the lubrication path 10 can be dissipated through the first radiator 21, thereby obtaining lubricating oil with a lower temperature, and then continuing to lubricate and cool components such as the gas turbine 01 and the generator 02.

[0047] Optionally, the first radiator 21 may be connected to the lubricating oil passage 13 to deliver lubricating oil to the first radiator 21 via the lubricating oil passage 13. Alternatively, the first radiator 21 and the second radiator 31 may be connected in parallel, and a control valve may be used to control the lubricating oil passage 13 to supply lubricating oil to at least one of the first radiator 21 and the second radiator 31.

[0048] The first radiator 21 may be provided on the auxiliary vehicle body 06 so as to achieve stable support for the first radiator 21 through the auxiliary vehicle body 06 and avoid the first radiator 21 occupying the space of the main vehicle body 05 and increasing the load of the main vehicle body 05 .

[0049] Optionally, the first heat dissipation assembly 20 may include a plurality of first heat sinks 21 to improve the heat dissipation effect through the plurality of first heat sinks 21 .

[0051] Based on the above configuration, the first radiator 21 can be provided to ensure that ice does not form at the first air inlet filter 0611 , the second air inlet filter 0612 and the third air inlet filter 0613 , thereby ensuring smooth air intake and further ensuring sufficient air intake volume.

[0052] In other embodiments, the auxiliary vehicle body 06 can also be provided with a filter inlet 0614 for the air intake of the combustion engine and a filter inlet 0615 for the air intake of the generator; the first radiator 21 can be arranged at at least one of the filter inlet 0614 for the air intake of the combustion engine and the filter inlet 0615 for the air intake of the generator. Based on the above arrangement, the first radiator 21 can be arranged to ensure that the filter inlet 0614 for the air intake of the combustion engine and the filter inlet 0615 for the air intake of the generator are free of ice, thereby ensuring the smoothness of the air intake.

[0053] In some embodiments, the auxiliary vehicle body 06 can have a fan accommodating cabin 061, which can be provided with a partition plate to divide the fan accommodating cabin 061 into a first accommodating space and a second accommodating space, and the first accommodating space and the second accommodating space are arranged along the up-down direction of the auxiliary vehicle body 06.

[0054] In addition, the ventilation of the gas turbine generator set can also be performed by a fan set, which can be arranged in the auxiliary vehicle body 06 to avoid occupying the space of the main vehicle body 05 and increasing the load of the main vehicle body 05.

[0055] The fan set can include a first fan and a second fan, the first fan is arranged in the first accommodating space, and the second fan is arranged in the second accommodating space. The first fan can be used to provide power for the ventilation of the gas turbine 01, and the second fan can be used to provide power for the ventilation of the generator 02. Of course, the fan set can also include a third fan, which can be used to provide power for the air intake of the gas turbine 01.

[0056] Based on the above arrangement, the first fan and the second fan can be arranged along the up-down direction, which can make full use of the space in the height direction of the auxiliary vehicle body 06, and is conducive to reducing the size of the auxiliary vehicle body 06 in the length direction.

[0057] In some embodiments, the main vehicle body 05 can include a load-bearing frame, which is at least spliced by a non-carbon steel beam and a carbon steel beam. Based on this arrangement, the load-bearing capacity of the main vehicle body 05 can be improved by the load-bearing frame, and it is also conducive to reducing the weight of the load-bearing frame, reducing the risk of overweight, and having the advantage of lightweight compared to the welded carbon steel frame in the related art while ensuring the load-bearing capacity.
