Description

Technical Field

[0001] This utility model belongs to the field of steam turbine generator technology, and specifically relates to an environmentally friendly steam turbine generator exhaust gas treatment device. Background Technology

[0002] During the operation of a steam turbine generator, its exhaust gas contains a large amount of particulate matter such as dust. In order to meet environmental emission standards, flue gas treatment devices are usually used to purify the exhaust gas. Among them, the filter is one of the core components, which is used to intercept dust in the flue gas and prevent it from being emitted into the atmosphere and causing pollution.

[0003] After prolonged operation, traditional flue gas treatment devices accumulate a large amount of dust on the filter surface. As the dust layer thickens, the filter resistance increases dramatically. Excessive resistance can cause airflow instability. When the filter is severely clogged with dust, its filtration performance drops significantly, failing to effectively intercept dust in the flue gas. This results in a large amount of dust being emitted into the atmosphere with the flue gas, severely violating environmental protection requirements and causing great harm to the surrounding environment and ecology.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an environmentally friendly steam turbine generator exhaust gas treatment device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an environmentally friendly steam turbine generator exhaust gas treatment device, comprising a main body, with an air inlet and an air outlet respectively connected to both ends of the main body. A dual-shaft power assembly is installed inside the air inlet, with one end of the dual-shaft power assembly engaging with an air intake promoting assembly located in the inner cavity of the air inlet. The other end of the dual-shaft power assembly is provided with a rotating cleaning mechanism located inside the main body. A filter is installed inside the main body, located on one side of the rotating cleaning mechanism.

[0008] Furthermore, the dual-axis power assembly includes a dual-axis motor, which is fixedly installed inside the air intake.

[0009] Furthermore, a power shaft is fixedly installed at one output end of the dual-axis motor, and a rotating gear is fixedly installed at the end of the power shaft away from the dual-axis motor.

[0010] Furthermore, a power shaft is fixedly installed at the other output end of the dual-axis motor, and a first rotating wheel is fixedly installed at one end of the power shaft. A V-shaped groove is formed on the first rotating wheel.

[0011] Furthermore, the air intake assembly includes a fixed gear, which is rotatably mounted inside the air intake and meshes with the rotating gear. A connecting rod is fixedly mounted on the fixed gear, and a rotating shaft is fixedly mounted on the connecting rod.

[0012] Furthermore, the rotating shaft has multiple fan blades arranged in a circular array on its circumferential surface, and a support frame is rotatably mounted on the other end of the rotating shaft, with the support frame fixedly mounted on the air inlet.

[0013] Furthermore, the rotating cleaning mechanism includes a rotating disk with a V-shaped outer wall. The outer wall of the rotating disk is located within the V-shaped groove of the first rotating wheel. Multiple support wheels are installed on the outer wall of the rotating disk, and V-shaped grooves are also formed on the multiple support wheels. Similarly, the outer wall of the rotating disk is also located within the V-shaped grooves of the multiple support wheels. The multiple support wheels are rotatably mounted on the inner wall of the main body.

[0014] Furthermore, a plurality of cleaning rods are fixedly installed on the inner ring of the rotating disk, and a plurality of cleaning brushes are fixedly installed on one end of the plurality of cleaning rods near the filter.

[0015] This utility model has the following beneficial effects:

[0016] 1. The rotating cleaning mechanism of this utility model rotates continuously under the drive of the dual-shaft power assembly, cleaning the dust off the surface of the filter and preventing excessive dust accumulation that could cause filter blockage. This device can maintain the filter's good filtration performance while ensuring effective filtration and purification of flue gas, ensuring the stable and efficient operation of the entire flue gas treatment process, so that the exhaust gas of the steam turbine generator meets environmental emission standards and reduces environmental pollution.

[0017] 2. When the dual-axis power assembly is started, it begins to rotate. Subsequently, the air intake assembly will rotate along with the dual-axis power assembly, promoting the rotation of the air intake assembly and generating thrust on the flue gas. This allows the flue gas to enter the main body at a faster speed, ensuring the continuity and efficiency of the flue gas treatment process and avoiding adverse phenomena such as flue gas accumulation or backflow at the air intake due to poor air intake.

[0029] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0031] Please see Figures 1-7 As shown, this utility model is an environmentally friendly steam turbine generator exhaust gas treatment device, including a main body 1. The two ends of the main body 1 are respectively connected to an air inlet 2 and an air outlet 3. A dual-shaft power assembly 4 is installed inside the air inlet 2. One end of the dual-shaft power assembly 4 is engaged with an air intake promoting assembly 5. The air intake promoting assembly 5 is located in the inner cavity of the air inlet 2. The other end of the dual-shaft power assembly 4 is provided with a rotating cleaning mechanism 6. The rotating cleaning mechanism 6 is located inside the main body 1. A filter 7 is installed inside the main body 1. The filter 7 is located on one side of the rotating cleaning mechanism 6.

[0032] The air intake 2 is installed on the engine's exhaust pipe. When the exhaust gas generated by the engine is discharged from the exhaust pipe and enters the air intake 2 connected to the exhaust pipe, the dual-shaft power assembly 4 is activated and begins to rotate. Subsequently, the intake assembly 5 will follow the dual-shaft power assembly 4 to rotate, promoting the rotation of the intake assembly 5 and generating thrust on the exhaust gas, thereby allowing the exhaust gas to enter the main body 1 at a faster speed. This ensures the continuity and efficiency of the exhaust gas treatment process and avoids adverse phenomena such as exhaust gas accumulation or backflow at the air intake 2 due to poor air intake.

[0033] The other end of the dual-shaft power assembly 4 drives the rotating cleaning mechanism 6 to rotate. The filter 7 inside the main body 1 intercepts and filters the dust in the flue gas. The purified flue gas is discharged from the outlet 3. As the filtration process continues, dust gradually accumulates on the surface of the filter 7. At this time, the rotating cleaning mechanism 6 continues to rotate under the drive of the dual-shaft power assembly 4 to clean the dust off the surface of the filter 7, preventing excessive dust accumulation from clogging the filter 7. This device can maintain the good filtration performance of the filter 7 while ensuring effective filtration and purification of the flue gas, ensuring the stable and efficient operation of the entire flue gas treatment process, so that the exhaust gas of the steam turbine generator meets the environmental emission standards and reduces pollution to the environment.

[0034] In one embodiment, the dual-axis power assembly 4 includes a dual-axis motor 401, which is fixedly installed inside the air inlet 2.

[0035] A power shaft 402 is fixedly installed at one output end of the dual-axis motor 401, and a rotating gear 403 is fixedly installed at the end of the power shaft 402 away from the dual-axis motor 401.

[0036] The air intake assembly 5 includes a fixed gear 501, which is rotatably mounted inside the air intake 2. The fixed gear 501 meshes with the rotating gear 403. A connecting rod 502 is fixedly mounted on the fixed gear 501, and a rotating shaft 503 is fixedly mounted on the connecting rod 502.

[0037] The rotating shaft 503 has a plurality of fan blades 504 arranged in a circular array on its circumferential surface. A support frame 505 is rotatably mounted on the other end of the rotating shaft 503, and the support frame 505 is fixedly mounted on the air inlet 2.

[0038] The dual-axis motor 401, located inside the air intake 2, starts operating. The dual-axis motor 401 has two output ends. One output end drives the fixedly mounted power shaft 402 to rotate. The rotating gear 403, fixedly mounted at the end of the power shaft 402 away from the dual-axis motor 401, also performs circular motion. Since the rotating gear 403 meshes with the fixed gear 501, when the rotating gear 403 starts rotating, the fixed gear 501 rotates accordingly. Simultaneously, the rotation of the fixed gear 501 drives the fixedly mounted connecting rod 502 to perform circular motion. The connecting rod 502 is fixedly connected to the rotating shaft 503, so the rotating shaft 503 also rotates. Multiple fan blades 504 arranged in a circular array on the circumferential surface of the rotating shaft 503 rotate... Driven by the rotating shaft 503, the fan blades 504 rotate at high speed. When the exhaust gas from the engine enters through the air inlet 2, the rotating fan blades 504 play two important roles in the exhaust gas process. First, the rotation of the fan blades 504 acts like a fan, providing an additional driving force to the exhaust gas, enabling it to flow more quickly and smoothly into the main body 1, ensuring the timely entry of the exhaust gas into the main body 1 for subsequent processing. Second, the rotation of the fan blades 504 makes the originally relatively chaotic exhaust gas in the air inlet 2 more orderly, allowing the exhaust gas to be evenly distributed within the air inlet 2, avoiding situations where there is too much or too little exhaust gas in certain areas. This helps the subsequent filter 7 to perform uniform and efficient filtration and purification of the exhaust gas, improving the overall working efficiency of the exhaust gas treatment device.

[0039] The other end of the rotating shaft 503 is rotatably mounted on the support frame 505, which is fixedly mounted on the air inlet 2. The support frame 505 provides stable support for the rotating shaft 503, ensuring that the rotating shaft 503 will not wobble or deviate during high-speed rotation.

[0040] In one embodiment, for the dual-axis motor 401, a power shaft 404 is fixedly installed at the other output end of the dual-axis motor 401, and a first rotating wheel 405 is fixedly installed at one end of the power shaft 404. A V-shaped groove is provided on the first rotating wheel 405.

[0041] The rotating cleaning mechanism 6 includes a rotating disk 601, the outer wall of which is V-shaped and located within the V-shaped groove of the first rotating wheel 405. Multiple support wheels 602 are mounted on the outer wall of the rotating disk 601, and V-shaped grooves are also provided on the multiple support wheels 602. Similarly, the outer wall of the rotating disk 601 is also located within the V-shaped grooves of the multiple support wheels 602. The multiple support wheels 602 are rotatably mounted on the inner wall of the main body 1.

[0042] Multiple cleaning rods 603 are fixedly installed on the inner ring of the rotating disk 601, and multiple cleaning brushes 604 are fixedly installed on one end of the multiple cleaning rods 603 near the filter 7.

[0043] When the dual-axis motor 401 starts, its other output end drives the power shaft 404 to rotate, thereby causing the first rotating wheel 405 fixed to one end of the power shaft 404 to rotate synchronously. Since the V-shaped groove of the first rotating wheel 405 and the rotating disk 601 on its V-shaped outer wall are nested together, the rotating disk 601 is driven to rotate by the friction between the two during the rotation of the first rotating wheel 405. Furthermore, the friction between the first rotating wheel 405 and the rotating disk 601 is much greater than the friction generated when the multiple cleaning brushes 604 clean the filter 7. Therefore, it can be ensured that the rotating disk 601 stably receives power from the first rotating wheel 405 and rotates without stopping or jamming due to the frictional resistance between the cleaning brushes 604 and the filter 7. When the rotating disk 601 rotates, its outer ring is supported and limited by multiple support wheels 602. The V-shaped groove of the support wheel 602 cooperates with the V-shaped outer wall of the rotating disk 601, ensuring both the stability of the rotating disk 601 during rotation and... By reducing frictional resistance and making rotation smoother, multiple cleaning rods 603 fixed on the inner ring of the rotating disk 601 move in a circular motion along with the rotating disk 601. The cleaning brushes 604 at the end of the cleaning rods 603 near the filter 7 continuously contact the surface of the filter 7. Due to the continuous rotation of the rotating disk 601, the cleaning brushes 604 can clean the entire filter surface of the filter 7, removing the dust particles adsorbed and accumulated by the filter 7 during the process of filtering flue gas. This ensures that the filter 7 maintains good filtration performance and avoids clogging of the filter 7 due to excessive dust accumulation. As a result, the entire flue gas treatment device can continuously and efficiently purify the flue gas discharged from the turbine generator, so that the purified flue gas can meet the environmental emission standards and be discharged into the atmosphere.
