Description

Technical Field

[0001] This invention belongs to the field of electrostatic dust removal technology, specifically relating to an electrostatic dust removal device driven by waste heat from industrial flue gas. Background Technology

[0002] Traditional high-efficiency electrostatic precipitators use high-voltage direct current generated by a high-voltage power supply system to charge dust particles, thus capturing them. However, the high-voltage power supply system consumes a huge amount of electricity, significantly increasing the cost of industrial production. During industrial production, chemical reactions to obtain the final product generate a large amount of heat, some of which is carried away by the flue gas produced. Industrial flue gas is highly calorific and often needs to be directly discharged into the environment through cooling towers, resulting in energy waste and thermal pollution. Recycling the flue gas generated during industrial production and using the generated electricity in electrostatic precipitators allows for the reuse of heat during flue gas treatment, significantly reducing industrial production costs. In the recycling process, the industrial flue gas needs to pass through an evaporative heat exchanger to exchange heat with the medium. The mechanical energy generated by the heat exchange is converted into electrical energy, which, after compensation by the power grid, can power the electrostatic precipitator again. However, the dust in the flue gas needs to be fully absorbed before entering the evaporative heat exchanger; otherwise, it will clog the heat exchanger's piping structure. Therefore, higher requirements are placed on the dust removal performance of the electrostatic precipitator.

[0003] Existing electrostatic precipitators primarily use rapping to shake off dust adsorbed on the plates. However, the rapping location is relatively singular, and areas far from the rapping location experience weaker vibrations, making it difficult for dust to be shaken off. As a result, dust accumulates on the plates, forming an isolation layer in the electric field and affecting the dust removal efficiency. If the flue gas directly enters the evaporative heat exchanger, it can damage subsequent heat exchange equipment. Therefore, it is essential to design an electrostatic precipitator driven by industrial flue gas waste heat. Summary of the Invention

[0004] The purpose of this invention is to provide a simple and rationally designed electrostatic precipitator driven by industrial flue gas waste heat in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] An electrostatic precipitator driven by waste heat from industrial flue gas includes a housing, an inlet pipe on one side of the housing, a discharge pipe on the other side of the housing, a ash hopper at the bottom of the housing, a discharge valve on the ash hopper, a dust removal mechanism inside the housing, a lifting mechanism inside the housing, and a drive mechanism outside the housing, which is connected to the lifting mechanism.

[0007] The lifting mechanism includes side support plates fixed inside the device housing. A drive wheel and a driven wheel are rotatably connected between the side support plates. A connecting belt is wound around the drive wheel and the driven wheel. A mounting frame is fixedly installed on the connecting belt, and a lifting platform is fixed on the mounting frame. The lifting platform is located between the connecting belts and is connected to a rotary transmission mechanism. An attachment treatment mechanism is provided on the rotary transmission mechanism, and a vibration mechanism is provided on the attachment treatment mechanism.

[0008] As a further optimization of the present invention, a sealing sleeve is provided on one side of the side support plate, and the edge of the connecting strip is in contact with the sealing sleeve. A flow guide is provided on the side support plate near the inlet pipe.

[0009] As a further optimization of the present invention, the rotary transmission mechanism includes a transmission gear rotatably connected to the lifting platform, the transmission gear meshing with a rack, lifting guide rails symmetrically arranged on the rack, a limit slider slidably connected on the lifting guide rails, the limit slider being fixed on the lifting platform, and T-blocks fixed at both ends of the rack, the T-blocks being fixed on the inner wall of the side support plate.

[0010] As a further optimization of the present invention, the transmission gear meshes with the connecting gear, the connecting gear is fixedly sleeved on the connecting sleeve, and the connecting sleeve is fixed at both ends of the rotating shaft.

[0011] As a further optimization of the present invention, the attachment treatment mechanism includes support blocks uniformly sleeved on the rotating shaft, a central sleeve between the support blocks, a first support rod between the support blocks, a cleaning scraper rotatably connected to the first support rod, a wiping block provided on the cleaning scraper, and a sealing mechanism provided on the cleaning scraper.

[0012] As a further optimization of the present invention, the sealing mechanism includes a sealing support plate symmetrically arranged on the central sleeve, a first arc-shaped cover slidably connected to the sealing support plate, the first arc-shaped cover being fixed on one side of the cleaning scraper, a cleaning spring being provided between the sealing support plate and the cleaning scraper, and a second arc-shaped cover being provided on the other side of the cleaning scraper, the second arc-shaped cover being slidably connected to the central sleeve.

[0013] As a further optimization of the present invention, the vibration mechanism includes a second support rod symmetrically fixed between the support blocks, a connecting plate rotatably connected to the second support rod, the connecting plate being fixed to the enclosed cover, and vibration springs symmetrically arranged on the connecting plate, one end of the vibration springs being connected to the central sleeve.

[0014] As a further optimization of the present invention, a connector is fixed in the closed cover, the closed cover is slidably connected to the central sleeve, and vibrating hammers are evenly arranged on the connector.

[0015] As a further optimization of the present invention, the driving mechanism includes a first roller and a second roller rotatably connected to the outer wall of the device housing. A transmission belt is wound around the first roller and the second roller. The first roller and the second roller are both fixedly sleeved on the drive shaft. The drive shaft is fixedly connected to the drive wheel. A drive motor is provided on the device housing. The output end of the drive motor is fixedly connected to one of the drive shafts.

[0016] As a further optimization of the present invention, the dust removal mechanism includes an inner support uniformly arranged in the outer shell of the device, a damper uniformly arranged on the inner support, a support spring arranged on the damper, the support spring being connected to the support frame, a dust collection plate being fixedly connected between the support frames, and a discharge line uniformly arranged between the outer shells of the device, the discharge line being located between two adjacent dust collection plates.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. In the dust removal process, the drive motor drives the active wheel in the lifting mechanism to rotate, which in turn drives the mounting frame on the connecting belt and the lifting platform to move up and down. The attachment treatment mechanism and the rapping mechanism on the lifting platform will move up and down with the lifting platform. By adjusting the position of the rapping mechanism, the tapping range of the rapping mechanism can cover the entire dust collection plate, preventing the fixed installation of the rapping mechanism from failing to shake off dust far away from the rapping position.

[0019] 2. This invention allows the cleaning scraper to indirectly contact the dust collection plate through the rotation of the rotating shaft. During the contact process, the scraping spring is squeezed and rotated towards the central sleeve, thus preventing damage to the dust collection plate from hard contact. At the same time, as the central sleeve rotates, the cleaning scraper will adhere tightly to the surface of the dust collection plate under the elastic force of the scraping spring, scraping off the dust adhering to the dust collection plate. As the cleaning scraper moves, the wiping block gradually replaces the cleaning scraper in contact with the dust collection plate, wiping away the dust remaining on the dust collection plate. Combined with the vibration mechanism, the dust adhering to the dust collection plate can be thoroughly removed, preventing dust adhesion from affecting the dust collection effect of the dust collection plate and preventing residual dust in the flue gas from affecting the heat exchange process of industrial flue gas.

[0020] 3. The present invention provides a sealing mechanism on the attachment treatment mechanism to prevent dust in the flue gas from entering. At the same time, the sealing cover is used to seal the rotating parts of the connecting plate and the central sleeve, which prevents dust from accumulating at the rotating parts during the falling process and causing the cleaning scraper and connecting plate to get stuck. This improves the stability of operation and reduces the maintenance cost in the later stage. Attached Figure Description

[0033] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0034] Example: Please refer to Figure 1-11 An electrostatic precipitator driven by waste heat from industrial flue gas includes a housing 1. One side of the housing 1 has an inlet pipe 2 for receiving flue gas, and the other side has an outlet pipe 3 for discharging purified flue gas. The bottom of the housing 1 has a dust hopper 4 for accumulating dust, and a discharge valve 5 at the outlet of the bottom of the hopper 4. Periodically opening the discharge valve 5 discharges the dust inside the hopper 4, preventing dust accumulation inside the device. A lifting mechanism 7 is installed inside the housing 1, and a drive mechanism 10 is installed outside the housing 1, connected to the lifting mechanism 7, for reciprocating operation. Inside the housing 1 is a dust removal mechanism 6, which uses electrostatic effects to adsorb dust within the housing 1, ultimately resulting in a dust-free environment. Dust-laden flue gas is discharged through exhaust pipe 3. An adhesion treatment mechanism 8 is installed on the lifting mechanism 7, which removes dust adhering to the dust removal mechanism 6. A rapping mechanism 9 is also installed on the adhesion treatment mechanism 8, which intermittently rapps the dust removal mechanism 6, promoting dust removal. The dust-free flue gas, after being cleaned by the dust removal mechanism 6, passes through exhaust pipe 3 into the evaporator heat exchanger to exchange heat with the medium in the evaporator tubes. This heat exchange causes the turbine expander to generate rotational mechanical energy. This rotational mechanical energy is then converted into alternating current by an induction generator and transmitted to the power grid. After grid compensation, it is transmitted as stable direct current through a high-voltage power supply system, again powering the electrostatic precipitator. This process achieves the goal of using waste heat from industrial flue gas to power the electrostatic precipitator.

[0035] Please see Figure 3-8 and Figure 11The dust removal mechanism 6 includes multiple sets of internal supports 61 evenly arranged in the outer casing 1. Two internal supports 61 in each set are fixed to the upper and lower sides inside the outer casing 1, respectively. Dampers 62 are evenly arranged on the two internal supports 61 in each set, and support springs 63 are mounted on the dampers 62. The support springs 63 are connected to support frames 64, and a dust collection plate 65 is fixedly connected between the two support frames 64. The support springs 63 provide elastic support for the dust collection plate 65 between the support frames 64. When the rapping mechanism 9 taps and vibrates the dust collection plate 65, the entire dust collection plate 65 will vibrate under the support of the support springs 63. 5. Shaking occurs. After the vibration ends, the damper 62 consumes the elastic potential energy accumulated in the support spring 63, which helps the dust collection plate 65 restore static balance. A discharge line 66 is provided between two adjacent dust collection plates 65. The discharge line 66 serves as the corona electrode of the device. The electrical energy converted from the waste heat of industrial flue gas is connected to the terminal on the top of the device shell 1 after being compensated by the power grid. The terminal supplies power to the discharge line 66 and the dust collection plate 65. When the dust comes into contact with the discharge line 66 with the flue gas, it will become negatively charged. After being charged, it will adhere to the dust collection plates 65 on both sides of the discharge line 66 under the adsorption of the positive charge of the dust collection plate 65.

[0036] Please see Figure 1-4 The drive mechanism 10 includes a first roller 101 and a second roller 102 rotatably connected to the outer wall of the device housing 1. A transmission belt 103 is wound around the first roller 101 and the second roller 102. The first roller 101 and the second roller 102 are both fixedly sleeved on the drive shaft 105. The drive shaft 105 is rotatably mounted on the device housing 1. The drive shaft 105 is fixedly connected to the lifting mechanism 7. A drive motor 104 is provided on the device housing 1. The output end of the drive motor 104 is fixedly connected to one of the drive shafts 105. During the process of the drive motor 104 driving the drive shaft 105 to rotate, it will drive the first roller 101 to rotate. Through the connection of the transmission belt 103, the second roller 102 will rotate synchronously, thereby causing the drive shaft 105 and the drive wheel 72 sleeved on the first roller 101 and the second roller 102 to rotate.

[0037] Please see Figure 2-7The lifting mechanism 7 includes multiple sets of side support plates 71 evenly installed on both sides inside the housing 1. A driving wheel 72 and a driven wheel 73 are rotatably connected between two side support plates 71 in each set. The driving wheel 72 is rotatably connected to the top side of the side support plate 71 via bearings, and the driven wheel 73 is rotatably connected to the bottom side of the side support plate 71 via bearings. A connecting belt 74 is wound around the driving wheel 72 and the driven wheel 73. The driving wheel 72 is connected to the drive shaft 105. The connecting belt 74 is made of high-temperature and corrosion-resistant fluororubber material, allowing for continuous use in complex flue gas environments. A sealing sleeve 78 made of silicone rubber is provided on one side of the connecting strip 74, and the edge of the connecting strip 74 fits against the sealing sleeve 78. The sealing sleeve 78 and the connecting strip 74 seal the space between the side support plates 71 to prevent the intrusion of flue gas and damage to the transmission structure. A guide hood 70 is provided on the side support plate 71 near the inlet pipe 2. The guide hood 70 can guide the flow direction of the flue gas, so that the flue gas flows through the dust collection plates 65 and prevents the flue gas from directly hitting the connecting strip 74. A mounting bracket 75 is fixedly installed on the connecting strip 74, and a lifting platform is fixed on the mounting bracket 75. 76. The lifting platform 76 is located inside the connecting belt 74 and within the enclosed space between the side support plates 71. The lifting platform 76 is connected to the rotary transmission mechanism 77, which includes a transmission gear 771 rotatably connected to the lifting platform 76. The transmission gear 771 meshes with a rack 772. A lifting guide rail 773 is symmetrically fixed on the rack 772. The lifting guide rail 773 can limit the movement of the limiting slider 774 between the lifting platforms 76. The rack 772 is fixed between the side support plates 71 by T-blocks 775 at its top and bottom. 1. A meshing connecting gear 776 is fixedly sleeved on a connecting sleeve 777. The connecting sleeve 777 is rotatably connected to a lifting platform 76. One end of the connecting sleeve 777 is fixedly connected to the end of a rotating shaft 778. During the process of the drive mechanism 10 driving the drive wheel 72 to rotate, it can drive the mounting bracket 75 on the connecting belt 74 and the lifting platform 76 to move up and down. During the up and down movement of the lifting platform 76, the transmission gear 771 will rotate under the meshing action of the rack 772, thereby driving the meshing connecting gear 776 to rotate, thereby driving the connecting sleeve 777 and the rotating shaft 778 to rotate.

[0038] Please see Figure 9-10The adhesion treatment mechanism 8 includes multiple support blocks 81 evenly sleeved on the rotating shaft 778. A central sleeve 82 is fixedly disposed between two support blocks 81. A first support rod 83 is disposed between the support blocks 81. The first support rod 83 has two sets of circumferentially distributed in the central sleeve 82. A nylon cleaning scraper 84 is rotatably connected to the first support rod 83. A high-density polyethylene wiping block 85 is disposed on the cleaning scraper 84. A sealing mechanism 86 is disposed on the cleaning scraper 84. The sealing mechanism 86 can prevent dust in the flue gas from accumulating in the rotation gap between the first support rod 83 and the cleaning scraper 84. The sealing mechanism 86 includes a sealing support plate 861 symmetrically disposed on the central sleeve 82. A first arc-shaped cover 862 is slidably connected to the sealing support plate 861. The first arc-shaped cover 862 is fixed on one side of the cleaning scraper 84. A cleaning spring 863 is provided between the cleaning scraper 84 and the cleaning scraper 61. The cleaning spring 863 is used to provide elastic support for the cleaning scraper 84. A second arc-shaped cover 864 is provided on the other side of the cleaning scraper 84. The second arc-shaped cover 864 is slidably connected to the central sleeve 82. During the rotation of the rotating shaft 778, the central sleeve 82 will rotate with it. After the cleaning scraper 84 contacts the dust collection plate 65, it will squeeze the cleaning spring 863 and flip it towards the central sleeve 82, thereby preventing hard contact from damaging the dust collection plate 65. At the same time, as the central sleeve 82 rotates, the cleaning scraper 84 will stick tightly to the surface of the dust collection plate 65 under the elastic force of the cleaning spring 863, and scrape off the dust adhering to the dust collection plate 65. As the cleaning scraper 84 moves, the wiping block 85 gradually replaces the cleaning scraper 84 in contact with the dust collection plate 65 and wipes the dust remaining on the dust collection plate 65.

[0039] Please see Figure 9-10 The vibration mechanism 9 includes two sets of second support rods 91 symmetrically fixed between the support blocks 81. These second support rods 91 are arranged in a circular pattern inside the central sleeve 82. A connecting plate 92 is rotatably connected to each second support rod 91. The connecting plate 92 is fixed to a sealing cover 93, which is slidably connected to the central sleeve 82. The sealing cover 93 seals the rotating parts of the connecting plate 92 and the central sleeve 82, preventing dust from entering. Vibration springs 94 are symmetrically arranged on the connecting plate 92, with one end of each spring connected to the central sleeve 82. The vibrating spring 94 provides elastic support for the connecting plate 92. A connector 95 made of flexible material is fixed in the enclosed cover 93. Vibrating hammers 96 are evenly arranged on the connector 95. When the vibrating hammers 96 strike the dust collection plate 65, they will cause the connector 95 to deform accordingly, thus avoiding damage to the dust collection plate 65. During the rotation of the central sleeve 82, the vibrating spring 94 will deform as the vibrating hammers 96 rotate, and then the vibrating hammers 96 will strike the dust collection plate 65 under the action of rotational force. The dust collection plate 65 will vibrate and shake off the accumulated dust.

[0040] It should be noted that in this type of electrostatic precipitator driven by industrial flue gas waste heat, the electrical energy converted from the industrial flue gas waste heat is connected to the terminal block on the top of the device housing 1 after grid compensation. This terminal block supplies power to the discharge wire 66 and dust collection plate 65 in the dust removal mechanism 6. As the industrial flue gas passes through the inlet pipe 2 and enters the device housing 1, it comes into contact with the discharge wire 66, which acts as a corona electrode. After becoming charged, the gas adheres to the dust collection plates 65 on both sides of the discharge wire 66 under the positive charge adsorption effect. The dust-free flue gas, after being cleaned by the dust removal mechanism 6, passes through the discharge pipe 3 and enters the evaporator heat exchanger. Subsequently, it is converted into AC power by the expander and generator and transmitted to the grid. After grid compensation, it is transmitted as stable DC power, which again supplies power to the dust removal mechanism 6. During the dust removal process, the drive motor 104 drives the drive wheel 72 in the lifting mechanism 7 to rotate, thereby… The mounting bracket 75 and lifting platform 76 on the connecting belt 74 move up and down. The attachment treatment mechanism 8 and the vibrating mechanism 9 move up and down with the lifting platform 76, thereby causing the rotating shaft 778 to rotate. During the rotation of the rotating shaft 778, the central sleeve 82 rotates as well. After the cleaning scraper 84 contacts the dust collection plate 65, it will squeeze the cleaning spring 863 and flip it towards the central sleeve 82, thus preventing hard contact from damaging the dust collection plate 65. At the same time, as the central sleeve 82 rotates, the cleaning scraper 84 will stick tightly to the surface of the dust collection plate 65 under the elastic force of the cleaning spring 863, scraping off the dust adhering to the dust collection plate 65. As the cleaning scraper 84 moves, the wiping block 85 gradually replaces the cleaning scraper 84 in contact with the dust collection plate 65, wiping the dust remaining on the dust collection plate 65. The shaken dust will fall into the ash discharge hopper 4 and be discharged centrally through the discharge valve 5 later.

[0041] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
