Summary of the invention

[0016] A technical effect of the present invention is:

[0017] In the embodiment of the present application, when the adjustable wet electrostatic precipitator of a thermal power plant needs to remove dust from the flue gas inside the dust removal box, the drive motor can be started. The drive motor will drive the rotating frame and the atomizing nozzle to rotate through the connecting pipe. At the same time, the movable disk will drive the guide rod to rotate through the output shaft, and the roller on the connecting ring will rotate. When the roller rotates, it will be squeezed by the top trapezoidal block. At this time, the guide rod can drive the movable disk to move downward, and then the atomizing nozzle can be rotated through the connecting rod and the first connecting rod. When the roller continues to rotate, the trapezoidal block does not squeeze the roller. At this time, the connecting rod will drive the atomizing nozzle to rotate in the opposite direction. Through the reciprocating rotation of the atomizing nozzle, the sprayed water mist can be more evenly mixed with the flue gas, thereby increasing the dust removal effect. This is the usage feature of the adjustable wet electrostatic precipitator of a thermal power plant.

[0018] In addition, when the adjustable thermal power plant wet electrostatic precipitator needs to remove dust from the flue gas inside the dust removal box, the driving motor and the output shaft can be used to make the rotating frame drive the atomizing nozzle to rotate, and with the cooperation of the roller and the trapezoidal block, the guide rod can drive the movable disk to move up and down, and at the same time, the connecting rod can drive the atomizing nozzle to rotate left and right. The horizontal rotation of the atomizing nozzle and the reverse rotation of the inclination angle can increase the dust removal range and achieve a better dust removal effect.

[0019] Furthermore, when the adjustable wet electrostatic precipitator of a thermal power plant needs to clean the waste slag and impurities inside the wastewater pool, the output shaft and the rotating disk can drive the second connecting rod to rotate. The rotation of the second connecting rod will drive the slider to slide along the inner wall of the wastewater pool, and at the same time drive the scraper to rotate along the bottom of the wastewater pool. The scraper can push the waste slag and impurities in the wastewater pool into the slag discharge port and drop them into the waste box through the slag discharge port. The waste box can also be removed from one side of the dust removal box, thereby facilitating the collection and cleaning of the waste slag and impurities in the wastewater pool.

[0020] Moreover, when the smoke exhaust duct and the air inlet duct need to be connected, the adjustable wet electrostatic precipitator of the thermal power plant can connect the smoke exhaust duct to one side of the air inlet duct, and then rotate the second screw to make the second screw drive the rotating block and the rotating ring to rotate through the sliding block, and then cooperate with the movable rod and the rotating shaft to move the arc-shaped pressing block out of the groove of the water inlet pipe. The arc-shaped pressing block can increase the sealing between the smoke exhaust duct and the air inlet duct, and at the same time it is convenient to connect and fix the smoke exhaust duct.

[0036] See also Figure 1 The present invention provides a technical solution: an adjustable wet electrostatic precipitator for a thermal power plant, comprising: a dust removal box 1 and a water pump 6, one side of the dust removal box 1 is connected with an air inlet pipe 2, an end of the dust removal box 1 away from the air inlet pipe 2 is connected with an air outlet pipe 3, a shell 4 is installed on the top of the dust removal box 1, a water pipe 5 is connected through the middle of the shell 4, and the water pump 6 is installed at one end of the water pipe 5;

[0037] The end of the water pipe 5 away from the water pump 6 is connected to a rotating joint 7, the bottom of the rotating joint 7 is connected to a connecting pipe 8, the bottom of the connecting pipe 8 is installed with an output shaft 9, the bottom of the output shaft 9 is connected to a driving motor 10 through a coupling, and a rotating frame 11 is installed around the connecting pipe 8. The bottom of the rotating frame 11 is connected to an atomizing nozzle 12 through a rotating shaft, and one side of the atomizing nozzle 12 is connected to a connecting rod 13 through a rotating shaft. The end of the connecting rod 13 away from the atomizing nozzle 12 is connected to a movable disk 14 through a rotating shaft, and the top of the movable disk 14 is connected to a guide rod 15 that penetrates the rotating frame 11. The outer side of the guide rod 15 A sleeve 16 is sleeved on the side, a movable spring 17 is sleeved between the sleeve 16 and the guide rod 15, a slide rod 18 is connected between the sleeve 16 and the slide groove of the shell 4, a connecting ring 19 is connected to the top of the guide rod 15, a roller 20 is installed on the top of the connecting ring 19, a trapezoidal block 21 is provided on the top of the roller 20, the side of the atomizing nozzle 12 away from the connecting rod 13 is connected to the first connecting rod 22 through a rotating shaft, the trapezoidal block 21 is installed at the bottom of the inner wall of the shell 4, the other end of the first connecting rod 22 is connected to one side of another group of atomizing nozzles 12 through a slide groove, and the movable disk 14 is sleeved on the outside of the output shaft 9.

[0038] During specific implementation, when the adjustable thermal power plant wet electrostatic precipitator is removing dust from the power plant flue gas inside the dust removal box 1, the drive motor 10 located in the groove of the wastewater pool 23 can be started. The top of the drive motor 10 is connected to the output shaft 9 through a coupling, so the drive motor 10 will drive the output shaft 9 to rotate. The top of the output shaft 9 is connected to the rotary joint 7 through a connecting pipe 8. The top of the rotary joint 7 is installed with a water pipe 5. When the output shaft 9 drives the rotary joint 7 to rotate, the rotary joint 7 is affected by the connecting pipe 8, so that the three groups of rotating frames 11 on the side can be rotated normally, and water is transported to the hose at the bottom of the rotating frame 11 through the water pipe 5 and the rotary joint 7, and the water is transported to the atomizing nozzle 12 through the hose, and then sprayed out through the atomizing nozzle 12;

[0039] A movable disk 14 is sleeved on the outer side of the output shaft 9, and the movable disk 14 can slide up and down through the protrusion on the outer side of the output shaft 9. A guide rod 15 is also installed on the top of the movable disk 14. A sleeve 16 is sleeved on the outer side of the guide rod 15, and the sleeve 16 can support and guide the guide rod 15 through a slide rod 18. A roller 20 is installed on the top of the four groups of guide rods 15 through a connecting ring 19. When the output shaft 9 rotates, the guide rod 15 passes through the through hole in the middle of the rotating frame 11, and the guide rod 15 passes through the through hole in the middle of the rotating frame 11. Under the action of the outer protrusion of the output shaft 9 and the rotating frame 11, the movable disk 14 will also rotate. When the movable disk 14 rotates, it will drive the top connecting ring 19 and the roller 20 to rotate through the guide rod 15, and the guide rod 15 will make the outer sleeve 16 drive the slide rod 18 to slide along the slide groove of the inner wall of the shell 4. The sleeve 16 and the slide rod 18 can increase the stability of the guide rod 15. A trapezoidal block 21 is also provided on the top of the roller 20. Since the trapezoidal block 21 is inverted on the top of the roller 20;

[0040] When the roller 20 rotates to the bottom of the trapezoidal block 21 through the connecting ring 19, since the position of the trapezoidal block 21 remains unchanged, the trapezoidal block 21 will squeeze the roller 20, so that the roller 20 drives the connecting ring 19 to move downward. The downward movement of the connecting ring 19 will cause the guide rod 15 to move downward along the sleeve 16, and the movable spring 17 between the sleeve 16 and the guide rod 15 will be in a compressed state. At the same time, the guide rod 15 will drive the movable disk 14 to move downward. One end of the movable disk 14 is connected to the guide rod 15. The rotating shaft is connected to the connecting rod 13, so the movable disk 14 moves downward, which will drive the connecting rod 13 to move downward. The other end of the connecting rod 13 is connected to the atomizing nozzle 12. When the connecting rod 13 moves downward close to one end of the movable disk 14, the atomizing nozzle 12 is pulled by the connecting rod 13 and rotates through the rotating shaft between the rotating frame 11. When the first group of atomizing nozzles 12 rotates, the second and third atomizing nozzles 12 are driven to rotate synchronously with the cooperation of the first connecting rod 22 and the slide groove.

[0041] On the contrary, when the roller 20 rotates to the side of the trapezoidal block 21, the roller 20 is not squeezed by the trapezoidal block 21, and then the movable spring 17 drives the guide rod 15 to reset, and makes the guide rod 15 move upward through the sleeve 16, and at the same time drives the movable disk 14 and the connecting rod 13 to move upward. One end of the connecting rod 13 moves upward, and it will push the atomizing nozzle 12 to rotate in the opposite direction through the rotating shaft. By repeating the above steps continuously, the atomizing nozzle 12 at the bottom of the three groups of rotating frames 11 can be reciprocated, and cooperate with the rotation of the connecting pipe 8 and the rotating frame 11, so that the water mist sprayed by the atomizing nozzle 12 covers a wider range, and it is convenient to adjust the spraying angle of the atomizing nozzle 12.

[0042] See also Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 It can be seen that when in use, the connecting pipe 8 and the rotating frame 11 can be driven to rotate by the driving motor 10 and the output shaft 9. At the same time, the movable disk 14 will rotate with the cooperation of the output shaft 9, and move up and down by the roller 20 and the trapezoidal block 21. The movable disk 14 moves up and down, which will cause the connecting rod 13 to drive the atomizing nozzle 12 to rotate back and forth, so that the spraying range of the atomizing nozzle 12 can be wider, and the dust removal effect of the flue gas can be increased.

[0043] A wastewater pool 23 is installed inside the dust removal box 1, and a scraper 24 is installed inside the wastewater pool 23. Slide blocks 25 are installed on both sides of the scraper 24. A second connecting rod 26 is connected to the top of a group of slide blocks 25, and a rotating disk 27 is connected to the end of the second connecting rod 26 away from the slide block 25. A slag discharge port 28 is opened in the middle of the wastewater pool 23, and a waste box 29 is arranged between the bottom of the slag discharge port 28 and the groove of the dust removal box 1. Wedge-shaped pressure blocks 30 are installed at both ends of the waste box 29, and a first screw 31 is installed on the top of the wedge-shaped pressure block 30. The outer side of the first screw 31 is sleeved with a first fixed block 32. A first sealing ring 33 is installed between the waste box 29 and the groove of the dust removal box 1, the first fixed block 32 is installed on the outer side of the dust removal box 1, and the rotating disk 27 is installed on the outer side of the output shaft 9.

[0044] In a specific implementation, the adjustable thermal power plant wet electrostatic precipitator can start the drive motor 10 when it is necessary to clean and collect the waste residue impurities in the wastewater pool 23. The drive motor 10 will drive the outer rotating disk 27 to rotate through the output shaft 9. The bottom of the rotating disk 27 is connected to a second connecting rod 26, and the other end of the second connecting rod 26 is connected to the slider 25. Therefore, when the rotating disk 27 rotates, the slider 25 on one side of the scraper 24 will be driven to rotate through the second connecting rod 26, and the slider 25 The scraper 24 slides along the slide groove on the inner wall of the wastewater tank 23, and is connected between two groups of sliders 25. When one group of sliders 25 rotates, the scraper 24 rotates along the bottom of the wastewater tank 23, and the other group of sliders 25 makes the scraper 24 more stable during rotation. By sliding the scraper 24 along the bottom of the wastewater tank 23, the waste residue and impurities can be pushed into the waste box 29 at the bottom of the dust removal box 1 through the slag discharge port 28, so as to facilitate the cleaning and collection of the waste residue and impurities at the bottom of the wastewater tank 23.

[0045] At the same time, the first screw 31 in the middle of the first fixed block 32 can also be rotated. Since the first screw 31 and the first fixed block 32 are threadedly connected, and the first screw 31 and the wedge-shaped pressing block 30 are connected through a bearing, and are guided by the light rod between the wedge-shaped pressing block 30 and the first fixed block 32, the first screw 31 will drive the wedge-shaped pressing block 30 to move in the direction of the second fixed block 32 when rotating. At this time, the wedge-shaped pressing block 30 will not squeeze the waste box 29. At this time, the waste box 29 can be quickly disassembled from the side of the dust removal box 1, thereby facilitating the cleaning of waste residues and impurities in the waste box 29;

[0046] On the contrary, the waste box 29 is installed in reverse to the inside of the dust removal box 1, and the first screw 31 is rotated in the reverse direction, so that the first screw 31 squeezes the waste box 29 through the wedge-shaped pressure block 30. At this time, the waste box 29 will move toward the dust removal box 1, and squeeze the first sealing ring 33 on the outside of the dust removal box 1 through the waste box 29. The deformation of the first sealing ring 33 can increase the sealing effect between the waste box 29 and the dust removal box 1.

[0047] See also Figure 1 , Figure 6 and Fig. 9 It can be seen that during use, in order to prevent the accumulation of waste residue and impurities in the wastewater tank 23, the rotation of the output shaft 9 can be used to drive the rotating disk 27 to rotate. When the rotating disk 27 rotates, the slider 25 can be driven to rotate through the second connecting rod 26. The scraper 24 can be rotated along the bottom of the wastewater tank 23 through the slider 25, so that the waste residue and impurities in the wastewater tank 23 can be pushed into the waste box 29, which is convenient for quickly cleaning and collecting the waste residue and impurities at the bottom of the wastewater tank 23.

[0048] A rotating ring 34 is installed inside the air inlet pipe 2 and the air outlet pipe 3. The inner side of the rotating ring 34 is connected to a movable rod 35 via a rotating shaft. The end of the movable rod 35 away from the rotating ring 34 is connected to an arc-shaped pressure block 36 via a rotating shaft. One end of the rotating ring 34 is connected to a connecting block 37 that passes through the air inlet pipe 2. One side of the connecting block 37 is connected to a sliding block 38 via a sliding groove. One side of the sliding block 38 is connected to a second screw 39 via a bearing. The outer side of the second screw 39 is sleeved with a second fixing block 40. Second sealing rings 41 are installed in the grooves on the end faces of the air inlet pipe 2 and the air outlet pipe 3. The second fixing block 40 is installed on the outer sides of the air inlet pipe 2 and the air outlet pipe 3.

[0049] During specific implementation, when it is necessary to connect the power plant smoke exhaust pipe with the air inlet pipe 2 or the air outlet pipe 3, the adjustable thermal power plant wet electrostatic precipitator can connect the pipe to one side of the air inlet pipe 2, and then rotate the second screw 39 passing through the middle of the second fixed block 40. Since the second screw 39 and the second fixed block 40 are threadedly connected, and the second screw 39 is connected to the sliding block 38 through a bearing, the sliding guide of the sliding block 38 in the sliding groove of the connecting block 37 causes the second screw 39 to generate a driving force on the connecting block 37 when rotating. Since the connecting block 37 passes through the air inlet pipe 2 and is connected to the rotating ring 34, the connecting block 37 is driven by the driving force of the second screw 39 to drive the rotating ring 34 to rotate, and the sliding block 38 slides along the sliding groove on one side of the connecting block 37. The inner wall of the rotating ring 34 is connected to the movable rod 35 through a rotating shaft. Therefore, the rotating ring 34 drives the movable rod 35 to rotate when rotating, and the movable rod 35 The other end of the movable rod 35 passes through the air intake pipe 2 and is connected to the arc-shaped pressing block 36 through the rotating shaft. Under the guiding effect of the groove of the air intake pipe 2 on the arc-shaped pressing block 36, the movable rod 35 generates a driving force on the arc-shaped pressing block 36 when rotating, so that the arc-shaped pressing block 36 can be pushed out of the groove of the air intake pipe 2, and the inclined surface of one side of the arc-shaped pressing block 36 squeezes the pipe. When the pipe is squeezed, it moves in the direction of the air intake pipe 2 and squeezes the second sealing ring 41 in the groove of the end surface of the air intake pipe 2, so that the second sealing ring 41 is deformed, at this time, the sealing effect between the air intake pipe 2 and the pipe can be increased. At the same time, by adjusting the rotation angle of the rotating ring 34, the arc-shaped pressing block 36 can play a squeezing and limiting role on pipes of different sizes, so that the user can quickly connect the smoke exhaust pipe with the air intake pipe 2. Similarly, the smoke exhaust pipe can be connected with the air outlet pipe 3 in the same way as above, so as to facilitate the transportation of smoke to subsequent treatment equipment.

[0050] On the contrary, it is only necessary to rotate the second screw 39 in the opposite direction, so that the second screw 39 pulls the connecting block 37 to rotate in the opposite direction through the sliding block 38, and makes the rotating ring 34 rotate in the opposite direction as well. Then, with the cooperation of the movable rod 35 and the rotating shaft, the arc-shaped pressing block 36 can be pulled into the groove of the air intake pipe 2, so that the arc-shaped pressing block 36 does not limit the smoke exhaust pipe. At this time, the smoke exhaust pipe can be removed from one side of the air intake pipe 2.

[0051] See also Figure 1 , Figure 4 and Figure 5 It can be seen that when in use, the smoke exhaust pipe can be docked with the air intake pipe 2 according to the use requirements, and by rotating the rotating ring 34, the rotating ring 34 drives the arc-shaped pressing block 36 to move from the groove of the air intake pipe 2 through the movable rod 35, and squeezes and limits the smoke exhaust pipe, thereby facilitating and quickly docking the pipes.

[0052] In summary, when the adjustable thermal power plant wet electrostatic precipitator is in use, the power plant exhaust pipe can be connected to the air inlet pipe 2 of the dust removal box 1 according to needs. At this time, the flue gas will be transported to the inside of the dust removal box 1, and the water pump 6 is started at the same time, so that the water pump 6 can transport water to the rotary joint 7 through the water pipe 5, and transport it to the atomizing nozzle 12 through the rotary joint 7 and the pipe in the rotating frame 11, and then sprayed out through the atomizing nozzle 12. The dust impurities in the flue gas can be adsorbed by the water mist and collected in the wastewater pool 23, so that the dust in the flue gas of the power plant can be removed. After the dust in the flue gas is settled, it can be discharged from the dust removal box 1 from the air outlet pipe 3 at the other end of the dust removal box 1, thereby completing the dust removal work of the flue gas of the power plant. This is the use feature of the adjustable thermal power plant wet electrostatic precipitator. The content not described in detail in this specification belongs to the prior art known to professional and technical personnel in this field.

[0053] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
