Description

Technical Field

[0001] The present invention relates to the technical field of waste heat recovery, and particularly to an integrated waste heat recovery device for a gas turbine power plant. Background Technique

[0002] The integrated waste heat recovery device for a gas turbine power plant is a complex and efficient energy recovery system, mainly composed of a waste heat boiler, a steam turbine system, a heat exchanger, a control system, etc. The waste heat boiler is the core device for waste heat recovery in a gas turbine power plant. It uses the high-temperature flue gas discharged from the gas turbine as a heat source, and heats water into steam through the heating surface system, which can be used for power generation, heating, or steam demand in industrial production processes;

[0003] The exhaust gas discharged from the gas turbine contains dust, impurities, and some viscous substances. These substances will gradually deposit on the heating surface of the waste heat recovery device, forming ash deposits. At the same time, due to water quality problems or the characteristics of the working medium, scale may also form on the heat transfer surfaces of equipment such as evaporators and condensers. Ash deposits and scaling will increase the thermal resistance, reduce the heat transfer efficiency, deteriorate the waste heat recovery effect, and also affect the normal operation of the equipment and increase the operating cost.

[0004] The Chinese patent document publication number is: "CN117387407B discloses a waste heat recovery device. Inside the housing main body, two support plates are clamped, which divide the housing main body into a heat exchange chamber and two transmission chambers. An inlet liquid pipe is arranged at the upper end of the heat exchange chamber, and an outlet liquid pipe is arranged at the bottom end of the heat exchange chamber. The housing main body includes a heat exchange adjustment mechanism and a heat exchange enhancement mechanism. The heat exchange adjustment mechanism includes a heat efficiency control module and an anti-slip guarantee module. The heat efficiency control module can select the heat exchange contact area according to the temperature of the hot gas to increase the heat exchange efficiency. The anti-slip guarantee module is used to ensure the stability of the heat efficiency control module after adjustment and prevent slipping. Through the design of the anti-slip guarantee module cooperating with the heat efficiency control module, it can adjust the contact area according to actual needs. When dealing with high-temperature gases, it can increase the heat exchange contact area to reduce waste of waste heat. When dealing with low-temperature gases, it can reduce the heat exchange contact area, thereby reducing the thermal resistance and ensuring the heat exchange efficiency." Although the above patent document can solve the problem of waste of waste heat, it cannot filter and treat the waste heat air and solve the problem that the deposition of dust on the heating surface affects the heating efficiency.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiment 1: Please refer to Figure 1 - Figure 12, A waste heat recovery integrated device for a gas turbine power plant shown in the figure includes: a housing 1 and pipes 2 fixed at both ends of the housing 1; it further includes: a heating surface unit installed in the housing 1, the heating surface unit is used to improve the heat transfer efficiency, and a movable sleeve 3 is arranged in the pipe 2, and at least two filter plates 4 are arranged in the movable sleeve 3. A jitter dust-removing mechanism is arranged in the pipe 2, and the jitter dust-removing mechanism is used to shake and clean the dust on the filter plates 4, and; a wiping mechanism arranged in the housing 1, the wiping mechanism is used to wipe and clean the heating surface of the heating surface unit. A steel frame is fixed on the housing 1 to bear the weight of the internal structure of the device and ensure the overall stability of the device. The central axis of the movable sleeve 3 is collinear with the central axis of the pipe 2;

[0037] Wherein, a guide groove b30 is fixed on the pipe 2, and a slide plate 31 slidably connected to the guide groove b30 is fixed on the movable sleeve 3. A pulley 32 is fixed on the slide plate 31, and the pulley 32 is slidably connected in the guide groove b30. The movable sleeve 3 slides in the guide groove b30 by using the pulley 32, which can greatly improve the smoothness of the movement of the movable sleeve 3 and has the advantage of high stability;

[0038] It should be noted that the heating surface unit includes: economizer, evaporator, superheater and steam drum. The economizer is arranged at the tail of the housing 1, which is used to heat the feed water and increase the water temperature, reduce the flue gas temperature, improve the boiler thermal efficiency, and through the evaporator tube bundle, the water in the tube absorbs heat and evaporates into steam. The superheater is used to further heat the saturated steam generated by the evaporator into superheated steam to meet the requirements of industrial production for steam quality. The main function of the steam drum is to store the steam-water mixture, separate the steam and water, ensure the steam quality, improve the steam purity, and at the same time the steam drum also plays a role in stabilizing the water level, providing guarantee for the safe operation of the boiler, so as to realize the generation of steam from waste heat. This is a conventional setting in this field, so it will not be elaborated in detail here;

[0039] It should also be noted that in this solution, the material of the filter plate 4 is a ceramic matrix composite material, which has extremely high high-temperature resistance, can withstand the high-temperature environment of the gas turbine exhaust gas, and at the same time has good wear resistance and corrosion resistance, can resist the erosion of dust particles and the acidic substances that may exist in the exhaust gas. In addition, the ceramic matrix composite material also has high strength and stiffness, can maintain structural stability during long-term filtration, and can effectively remove fine dust particles in the exhaust gas.

[0040] Furthermore, the jitter dust-falling mechanism includes: a rod body 6 is fixed inside a movable pipe sleeve 3 through a mounting block 5, and a filter plate 4 is slidably penetrated between the rod body 6. A spring 7 is fixedly connected to the adjacent side walls of the two filter plates 4, and the spring 7 is sleeved on the surface of the rod body 6. A plurality of limiting plates 8 are fixed inside the pipe 2, and the limiting plates 8 are in contact with the filter plates 4. A reciprocating member adapted to the movable pipe sleeve 3 is arranged inside the pipe 2. The vertical cross-section of the limiting plate 8 is L-shaped. A rubber plate 33 is fixed to the side wall of the limiting plate 8 close to the filter plate 4, and the rubber plate 33 is in contact with the filter plate 4. By adding the rubber plate 33, a certain buffering effect can be provided when the limiting plate 8 comes into contact with the filter plate 4, and furthermore, the situation that the filter plate 4 is damaged due to excessive bump impact can be reduced;

[0041] Among them, the reciprocating member includes: a main shaft 9 is rotatably connected to the pipe 2 through a mounting seat, and a bracket 10 is fixed to the pipe 2. A servo motor 11 fixed to the main shaft 9 is fixed to the bracket 10. A plurality of secondary shafts 12 are rotatably connected to the pipe 2. A worm 13 is fixed to the main shaft 9, and a worm gear 14 meshing with the worm 13 is fixed to one of the secondary shafts 12. Spur gears 15 meshing with each other are fixed to the two secondary shafts 12. A toothed plate 16 is fixed to the movable pipe sleeve 3, and the toothed plate 16 is slidably connected to the pipe 2. A sector gear 17 meshing with the toothed plate 16 is fixed to the secondary shaft 12. The diameter value of the spur gear 15 is greater than the length value of the sector gear 17;

[0042] In addition, at least two guide grooves a27 are fixed inside the pipe 2, and at least two mounting plates 28 are fixed to the movable pipe sleeve 3. The mounting plates 28 are slidably connected to the guide grooves a27, and the length value of the guide grooves a27 is greater than the length value of the mounting plates 28. A plurality of rollers 29 are fixed to the mounting plates 28, and the rollers 29 are slidably connected to the guide grooves a27. The cross-section of the mounting plate 28 is T-shaped. By adding the rollers 29, the guide grooves a27 and the mounting plates 28, the stable and smooth movement of the movable pipe sleeve 3 during reciprocating movement can be significantly improved, thereby preventing the situation of jamming or even getting stuck when the movable pipe sleeve 3 moves;

[0043] It should be noted that by driving the movable pipe sleeve 3 and the filter plate 4 to move left and right reciprocally, the vibration effect is generated by the collision between the filter plate 4 and the limiting plate 8. This process effectively realizes the goal of shaking and cleaning the impurities attached to the surface of the filter plate 4. The implementation of this method further reduces the possibility of dust and other impurities carried in the exhaust gas discharged by the gas turbine from entering the inside of the housing 1, thus avoiding the situation that the heat transfer efficiency is affected by excessive deposition on the heating surface and ensuring the efficient operation of the entire system;

[0044] Principle of cleaning the air filter plate 4 using the jitter ash-dropping mechanism: Driven by the servo motor 11, the shaft body rotates synchronously, driving the worm 13 to rotate synchronously. Utilizing the meshing transmission between the worm 13 and the worm wheel 14, one secondary shaft 12 rotates, and through the meshing transmission of two spur gears 15, the two secondary shafts 12 rotate in opposite directions, driving the coaxial sector gears 17 to rotate synchronously. By using the meshing transmission between one of the sector gears 17 and the toothed plate 16, the sector plate is driven to move. Then, by using the other sector gear 17 to continue meshing with the sector plate, the toothed plate 16 is driven to return to the initial position, achieving the purpose of driving the reciprocating movable sleeve 3 to move reciprocally. When the limiting plate 8 collides with the air filter plate 4, the air filter plate 4 vibrates when impacted, and the generated vibration is used to shake off and clean the dust adhering to the surface of the air filter plate 4.

[0045] In this solution, the process of cleaning the exhaust gas dust and ash accumulation of the gas turbine is as follows:

[0046] First, the reciprocating member drives the movable sleeve 3 and the air filter plate 4 to move left and right reciprocally. By using the vibration generated by the reciprocating movement, the dust adhering to the surface of the air filter plate 4 can be shaken off, achieving the purpose of cleaning the impurities carried in the exhaust gas and adhering to the air filter plate 4.

[0047] Second, by using the transmission of the connecting rod 21, the wiping mechanism is linked with the jitter ash-dropping mechanism, driving the spiral brush roller 23 to clean the surface of the heating surface, and then achieving the purpose of cleaning the ash accumulation on the heating surface.

[0048] Embodiment 2: Refer to Figure 3 、 Figure 5 、 Figure 11 and Figure 12 As shown, this embodiment further illustrates the embodiment, and the difference lies in disclosing a cleaning method for the impurities on the heating surface.

[0049] Specifically, the wiping mechanism includes: At least two guide rods 18 are fixed on the outer shell 1. At least two transmission plates 19 are slidably connected inside the outer shell 1. The transmission plates 19 are slidably penetrated through the guide rods 18 through sliding sleeves 20. A connecting rod 21 is hinged between the transmission plates 19 and the movable sleeve 3. A spiral brush roller 23 is rotatably connected to the transmission plates 19 through a rotating seat 22. A small gear 24 is fixed on the spiral brush roller 23. A rack a 25 meshing with the small gear 24 is fixed inside the outer shell 1;

[0050] Furthermore, at least two rack bars b26 are fixedly arranged inside the outer shell 1. The pinion gear 24 is meshed and connected with the rack bars b26. The rack bar a25 and the rack bars b26 are respectively located on both sides of the pinion gear 24. The length of the rack bar a25 is less than that of the rack bars b26, and the rack bar a25 and the rack bars b26 are not connected end to end. By using the pinion gear 24 to be respectively meshed and driven with the rack bar a25 and the rack bars b26, the multiple spiral brush rollers 23 can be rotated in different directions;

[0051] It should be noted that through the wiping mechanism provided, the spiral brush roller 23 can thoroughly clean the heating surface in a regular and uniform manner during the reciprocating motion. This efficient cleaning mechanism can effectively remove the ash adhering to the heating surface, thereby avoiding the problem that the ash has a negative impact on the heat transfer efficiency. Through such a cleaning process, it is ensured that the waste heat recovery effect of the device can always be maintained in a good state, thereby improving the operation efficiency and energy utilization efficiency of the entire system;

[0052] It should also be noted that four spiral brush rollers 23 are provided. The upper and lower spiral brush rollers 23 are meshed and driven with the rack bar a25, and the two spiral brush rollers 23 in the middle position are meshed with the rack bars b26;

[0053] The principle of using the wiping mechanism to clean the dust on the heating surface: By the left and right reciprocating movement of the movable pipe sleeve 3, using the transmission effect of the connecting rod 21, the transmission plate 19 is forced to move up and down reciprocally along the surface of the guide rod 18, thereby driving the spiral brush roller 23 to move synchronously. By using the pinion gear 24 to be respectively meshed and driven with the rack bar a25 and the rack bars b26, the spiral brush roller 23 is driven to rotate self - concurrently while moving up and down reciprocally, and the dust on the surface of the heating surface is cleaned by the spiral brush roller 23.

[0054] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non - exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to this process, method, article or device.

[0055] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
