Description

Technical Field

[0001] The present invention relates to the technical field of denitration and desulfurization, and in particular to a flue gas denitration and desulfurization washing device and a denitration and desulfurization method. Background Art

[0002] The smoke produced by the burning of harmful substances usually contains harmful gases such as sulfur and nitrate. If it is not treated and directly discharged, it will cause great harm to the environment. Desulfurization and denitrification is the process of purifying the harmful sulfur and nitrate gases contained in the flue gas, so that the emitted gas meets the emission standards and prevents air pollution.

[0003] The patent with the patent announcement number CN115253649B discloses a flue gas denitration and desulfurization washing device and a denitration and desulfurization method, which relates to the field of desulfurization and denitrification technology. The flue gas denitration and desulfurization washing device and the denitration and desulfurization method include a device body, the device body includes a shielding part and a purification part, and the device body is installed with: a driving motor, the driving motor is fixed on the top of the shielding part, and the output shaft of the driving motor movably penetrates the shielding part. This patent, by setting a driving motor, can drive the drainage drum to rotate, and the drainage cone can be used to perform drainage purification operations during the rotation of the drainage drum. The discharged solution will adhere to the inner wall of the device body, and at the same time, the drainage drum will drive the arc blades to rotate during the rotation, and the arc blades will push the flue gas toward the inner wall of the purification part, thereby prompting the flue gas to contact and purify the solution.

[0004] However, the device still has some shortcomings: the device purifies sulfur and nitrate in the flue gas through a purification solution to ensure emission quality. However, after harmful particles in the smoke enter the device, a small amount of harmful particles are easily attached to the inner wall of the device and mixed with the purification solution, making it difficult to discharge. Over time, harmful substances continue to accumulate and harmful gases such as sulfur and nitrate continue to volatilize, which can easily lead to a reduction in the purification quality of the washing device for the sulfur and nitrate gases entering the device.

When the device body passes through its own external When the wall mounting assembly is installed inside the smoke outlet pipe for use, the heating assembly inside the interlayer of the device body is started, and the heat emitted by the heating assembly increases the temperature inside the device body. At this time, the purified liquid flows into the purification assembly through the supply box, and the motor is started. When the output end of the motor rotates, it drives the supply box to rotate, and the supply box drives the purification assembly to rotate. The purification assembly uses the centrifugal force of rotation to rotate the purified liquid inside itself through the spray assembly into the interior of the device body and adhere to its inner wall to purify the flue gas. The purified flue gas is discharged through the gap between the top of the device body and the fixed plate to avoid polluting the atmosphere; when the purification assembly rotates, it drives the cross plate to rotate, and the cross plate drives the scraper to rotate and scrape along the inner wall of the device body. At the same time, the scraper drives the spoiler to rotate and disturb inside the device body, thereby accelerating the flow rate of the flue gas entering the device body, and the spoiler drives and the vertical rod to move synchronously, and the vertical rod drives the fan plate to revolve, thereby expanding the disturbance range of the spoiler.

[0007] According to the above technical solution, the plurality of spraying assemblies are equidistantly distributed on the outer wall of the purification assembly, the bottom of the scraper is slidably installed on the bottom of the inner wall of the device body, and the outer wall of the scraper is in contact with the inner wall of the device body, and a torsion spring is arranged between the fan plate and the vertical rod.

[0008] According to the above technical solution, the uniform device includes a fixed rod, a guide hemispherical block, a plurality of resistance rods and a plurality of elastic telescopic columns, the bottom of the fixed rod is fixedly installed at the bottom of the inner wall of the device body, the guide hemispherical block penetrates inside and is fixedly installed on the outer wall of the fixed rod, the tops of the plurality of resistance rods are equidistant and fixedly installed on the outer wall of the guide hemispherical block, the fixed ends of the plurality of elastic telescopic columns are equidistant and fixedly installed below the outer wall of the fixed rod, when the purification component rotates, the fixed rod remains stationary through the device body, at this time, the rotating fan plate contacts the arc surface of the outer wall of the resistance rod to generate a resistance force, at this time, the hinge shaft of the fan plate starts to rotate and rotates with its own hinge The connecting shaft is the axis that swings along the outer wall of the vertical rod in the opposite direction of its own revolution. When the swinging fan plate passes the resistance rod, it is automatically reset by the torsion spring. The reciprocating motion enables the fan plate to swing back and forth. At the same time, the guide hemispherical block is kept stationary by the fixed rod, and the smoke entering from the bottom of the device body is guided toward the fan plate through its lower arc surface. During the rotation of the spoiler, the spoiler hits the arc surface of the telescopic end of the elastic telescopic column to generate vibration, and the telescopic end of the elastic telescopic column contracts toward the fixed end through the resistance of the spoiler, and then automatically resets by its own built-in spring. At the same time, the hollow design of the spoiler can enhance its own vibration effect.

[0009] According to the above technical solution, the top end of the fixing rod passes through and is located inside the purification component, the arc surface of the outer wall of the abutting rod is located on the movement trajectory of the fan plate, and the arc surface of the telescopic end of the elastic telescopic column is located on the movement trajectory of the spoiler.

[0010] According to the above technical scheme, the uniform device also includes a filter plate, an inclined rod, a diverter block and a cam, the filter plate is fixedly installed on the outer wall of the fixed rod near the center of the purification component, the filter plate is located inside the purification component, the bottom of the inclined rod is fixedly installed on the outer wall of the fixed rod, the inclined rod is located above the filter plate, the bottom of the inner wall of the diverter block is fixedly installed on the top of the inclined rod, and the diverter block is hollow in design, the bottom of the cam is fixedly installed on the bottom of the inner wall of the purification component, and the internal movement of the cam penetrates the outer wall of the fixed rod. When the purification component rotates, the fixed rod limits the filter plate, and at the same time, the fixed rod limits the inclined rod, and the inclined rod limits the diverter block to make it stationary. When the purified liquid in the supply box flows into the purification component, the diverter block guides it, and causes the purified liquid to disperse and flow downward along the outer wall of the diverter block through the arc surface of its own outer wall. At this time, the purification component drives the purified liquid to rotate and continuously flushes the filter plate.

[0011] According to the above technical scheme, the anti-adhesion device includes a sliding plate, a circular wheel and a grooved arc plate. The sliding plate is slidably installed on the outer wall of the filter plate near the axis of the fixed rod, the top of the circular wheel is fixedly installed on the bottom of the sliding plate, and the slotted arc plate is fixedly installed between the outer wall of the sliding plate and the outer wall of the filter plate near the axis of the fixed rod. The slotted arc plate is elastic. When the cam rotates, its own outer wall continuously contacts the outer wall of the circular wheel. Under the contact of the cam, the outer wall of the circular wheel continuously slides along the outer wall of the cam. Thus, the cam enables the circular wheel to move along its own outer wall toward the fixed rod and reset, and the circular wheel drives the sliding plate to slide synchronously along the outer wall of the filter plate. When the sliding plate slides, the slotted arc plate is squeezed to deform synchronously and reset, and the elasticity of the slotted arc plate causes the outer wall of the circular wheel to always fit closely to the outer wall of the cam.

[0012] According to the above technical solution, the anti-adhesion device also includes a T-shaped arc block, a hinged plate, a transmission plate, a through rod and a semicircular block. The T-shaped arc block is fixedly installed on the inner wall of the sliding plate near the fixed rod. The hinged plate is hinged between the top of the T-shaped arc block and the bottom edge of the diverter block. The bottom of the transmission plate is hinged to the outer wall of the hinged plate near the fixed rod. The bottom of the through rod is penetrated by a spring and slidably installed inside the fixed rod. The bottom of the semicircular block is fixedly installed on the top of the through rod. The sliding plate slides toward the fixed rod and resets The T-shaped arc block is driven to move synchronously, and the T-shaped arc block pulls the hinged plate to move at the same time. The top of the hinged plate is restricted by the diverter block, prompting its own hinge shaft to start rotating. The hinged plate rotates away from the fixed rod with the hinge shaft as the axis, and the hinged plate drives the transmission plate to move synchronously. The hinge shaft of the transmission plate starts to rotate and pulls the semicircular block downward. The semicircular block presses the through rod to slide downward inside the fixed rod. After that, the through rod pushes the semicircular block to reset quickly when it is reset by the spring. During the up and down movement of the semicircular block, the purified liquid under the diverter block is disturbed upward.

[0013] According to the above technical solution, the bottom of the T-shaped arc block contacts the top of the filter plate, and the bottom of the semicircular block is hinged to the top of the transmission plate.

[0014] A denitration and desulfurization method for a flue gas denitration and desulfurization scrubbing device comprises the following steps: S1: Purification liquids with different components are injected into the supply box through multiple supply holes on the top of the supply box. At this time, the supply box is kept stable by the limit of the fixed plate, and the fixed frame limits the fixed plate; S2: When the device body is installed inside the smoke outlet pipe through the installation component on its outer wall for use, the heating component inside the interlayer of the device body is started, and the heat emitted by the heating component increases the temperature inside the device body; S3: The purification liquid flows into the purification component through the supply box, and the motor is started. When the output end of the motor rotates, the supply box is driven to rotate, and the supply box drives the purification component to rotate. The purification component uses the centrifugal force of rotation to rotate the purification liquid inside the device through the spraying component and spray it into the device body and adhere to its inner wall to purify the flue gas. S4: When the purification component rotates, it drives the horizontal plate to rotate, and the horizontal plate drives the scraper to rotate and scrape along the inner wall of the device body. At the same time, the scraper drives the spoiler to rotate and disturb inside the device body, and the spoiler drives the vertical rod to move synchronously, and the vertical rod drives the fan plate to revolve.

[0015] The present invention provides a flue gas denitration and desulfurization scrubbing device and a denitration and desulfurization method, which have the following beneficial effects: (1) The present invention, through the setting of the anti-pollution device, cooperates with the supply box, purification component, spray component, horizontal plate, scraper, spoiler, vertical rod and fan plate, so that the flue gas carrying nitrate and sulfur substances enters the main body of the device and is purified by the purification liquid. The heat of the heating component accelerates the evaporation rate of water vapor in the flue gas, effectively improves the fluidity and distribution uniformity of the flue gas, and increases the contact efficiency between sulfur and nitrate and the purification liquid, thereby improving the purification quality; and further increases the contact rate between harmful substances such as sulfur and nitrate in the flue gas and the purification liquid, thereby increasing the desulfurization and denitrification speed; at the same time, the scraper prevents a small amount of harmful particles in the flue gas from adhering to the inner wall of the main body of the device and mixing with the purification solution and being difficult to discharge, thereby preventing the harmful substances from continuously volatilizing harmful gases such as sulfur and nitrate, which leads to a decrease in the overall purification quality of the flue gas by the device.

[0016] (2) The present invention, through the setting of a uniform device, cooperates with the purification component, the fixed rod, the guide hemispherical block, the resistance rod, the elastic telescopic column, the filter plate, the inclined rod, the diversion block and the cam, so that the spoiler plate relies on the vibration force to shake off the flue gas particles attached to its outer wall, thereby preventing the effective substances in the flue gas from fumigating and corroding the spoiler plate. At the same time, the reciprocating swing of the fan plate causes itself to increase the disturbance efficiency of the flue gas inside the device body at the same rotation frequency, thereby preventing the flue gas flow speed from being too fast and directly causing the desulfurization and denitrification quality to fail to meet the standards; at the same time, the filter plate relies on the filter holes on its own outer wall to continuously disturb and refine the purified liquid, thereby facilitating the full mixing of the purified liquid with other additives, and the filter plate intercepts the sediment in the purified liquid, thereby ensuring that the desulfurization and denitrification effects are not affected and effectively preventing the sediment from clogging the spray port of the spray component, thereby preventing the spray liquid from being difficult to spray; the rotation of the purification component drives the cam to rotate.

[0017] (3) The present invention adopts the setting of the anti-adhesion device, and cooperates with the cam, sliding plate, round wheel, slotted arc plate, T-shaped arc block, hinged plate, transmission plate, through rod and semicircular block. The sliding plate is used to crush the sediment attached to the surface of the filter plate, so that the sediment is re-mixed with the purified liquid, and the sediment is prevented from clogging the filter holes of the filter plate and making it difficult to flush the purified liquid. At the same time, when the slotted arc plate is deformed, the flushing force of the purified liquid around the filter plate is increased, and the mixing uniformity of the purified liquid and other additives is improved; and the flow frequency of the purified liquid around itself is accelerated by the diverter block and the semicircular block, so that the purified liquid can fully combine with the sediment before being discharged from the purification component to avoid the purification effect of the purified liquid being reduced. At the same time, during the sliding process of the T-shaped arc block, the concave surface of the T-shaped arc block is used to guide and push away the purified liquid flushed by the filter plate for a second time, so as to prevent the filter plate from reciprocatingly flushing the purified liquid around itself, thereby reducing the flushing effect.

[0022] Several spraying components 43 are evenly distributed on the outer wall of the purification component 42. The bottom of the scraper 45 is slidably installed on the bottom of the inner wall of the device body 1, and the outer wall of the scraper 45 contacts the inner wall of the device body 1. A torsion spring is arranged between the fan plate 48 and the vertical rod 47.

[0023] During use, purified liquids of different components are injected into the supply box 41 through the multiple supply holes on the top of the supply box 41. At this time, the supply box 41 is kept stable by the limit of the fixed plate 21, and the fixed frame 2 limits the fixed plate 21. When the device body 1 is installed in the smoke outlet pipe through the installation component of its own outer wall for use, the heating component 11 in the interlayer of the device body 1 is started, and the heat emitted by the heating component 11 increases the internal temperature of the device body 1. At this time, the purified liquid flows into the purification component 42 through the supply box 41, and the motor 31 is started. When the output end of the motor 31 rotates, it drives the supply box 41 to rotate, and the supply box 41 drives the purification component 42 to rotate. The purification component 42 uses the centrifugal force of rotation to rotate the purified liquid inside itself through the spraying component 43 into the interior of the device body 1 and adheres to its inner wall to purify the flue gas. The purified flue gas is discharged through the gap between the top of the device body 1 and the fixed plate 21 to avoid polluting the atmosphere.

[0024] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes a uniform device 5; The uniform device 5 includes a fixed rod 51, a guide hemispherical block 52, a plurality of resistance rods 53 and a plurality of elastic telescopic columns 54. The bottom of the fixed rod 51 is fixedly installed at the bottom of the inner wall of the device body 1. The guide hemispherical block 52 passes through and is fixedly installed on the outer wall of the fixed rod 51. The tops of the plurality of resistance rods 53 are equidistantly and fixedly installed on the outer wall of the guide hemispherical block 52. The fixed ends of the plurality of elastic telescopic columns 54 are equidistantly and fixedly installed below the outer wall of the fixed rod 51. Through the above coordination, the spoiler 46 relies on vibration force to shake off the flue gas particles attached to its outer wall, preventing the effective substances in the flue gas from fumigating and eroding the spoiler 46. At the same time, the reciprocating swing of the fan plate 48 causes itself to increase the disturbance efficiency of the flue gas inside the device body 1 at the same rotation frequency, avoiding the excessive flow speed of the flue gas directly leading to substandard desulfurization and denitrification quality.

[0025] The top end of the fixing rod 51 passes through and is located inside the purification component 42 , the arc surface of the outer wall of the abutting rod 53 is located on the movement track of the fan plate 48 , and the arc surface of the telescopic end of the elastic telescopic column 54 is located on the movement track of the spoiler 46 .

[0026] The uniform device 5 also includes a filter plate 55, an inclined rod 56, a diverter block 57 and a cam 58. The filter plate 55 is fixedly mounted on the outer wall of the fixed rod 51 near the center of the purification component 42, the filter plate 55 is located inside the purification component 42, the bottom of the inclined rod 56 is fixedly mounted on the outer wall of the fixed rod 51, and the inclined rod 56 is located above the filter plate 55. The bottom of the inner wall of the diverter block 57 is fixedly mounted on the top of the inclined rod 56, and the diverter block 57 is hollow in design. The bottom of the cam 58 is fixedly mounted on the bottom of the inner wall of the purification component 42, and the internal movement of the cam 58 penetrates the outer wall of the fixed rod 51. Through the above cooperation, the filter plate 55 is relied on to continuously disturb and refine the purified liquid through the filter holes on its own outer wall, so as to facilitate the full mixing of the purified liquid with other additives, and the filter plate 55 intercepts the sediment in the purified liquid, while ensuring that the desulfurization and denitrification effects are not affected, effectively avoiding the sediment from clogging the spray port of the spray component 43, and preventing the spray liquid from being difficult to spray; when the purification component 42 rotates, the cam 58 is driven to rotate.

[0027] When in use, when the purification component 42 rotates, the fixed rod 51 remains stationary through the device body 1. At this time, the rotating fan plate 48 contacts the arc surface of the outer wall of the resistance rod 53 to generate a resistance force. At this moment, the hinge axis of the fan plate 48 begins to rotate and swings along the outer wall of the vertical rod 47 in the opposite direction of its own revolution with its own hinge axis as the axis. When the swinging fan plate 48 passes over the resistance rod 53, it is automatically reset by the torsion spring, and the reciprocating movement of the fan plate 48 enables the fan plate 48 to swing back and forth. At the same time, the guide hemispherical block 52, which is kept stationary by the fixed rod 51, is moved by its own lower arc surface. The smoke entering from the bottom of the device body 1 is guided toward the fan plate 48, and the spoiler 46 hits the arc surface of the telescopic end of the elastic telescopic column 54 during rotation to generate vibration, and the telescopic end of the elastic telescopic column 54 contracts toward the fixed end through the resistance of the spoiler 46, and then automatically resets through its own built-in spring. At the same time, the hollow design of the spoiler 46 can enhance its own vibration effect. Through the above cooperation, the spoiler 46 is prompted to rely on the vibration force to shake off the smoke particles attached to its outer wall, so as to prevent the effective substances in the smoke from being fumigated and eroding the spoiler 4. 6. At the same time, the reciprocating swing of the fan plate 48 increases the disturbance efficiency of the flue gas inside the device body 1 at the same rotation frequency, thereby preventing the flue gas from flowing too fast and directly causing the desulfurization and denitrification quality to be substandard; when the purification component 42 rotates, the fixed rod 51 limits the filter plate 55, and at the same time, the fixed rod 51 limits the inclined rod 56, and the inclined rod 56 limits the diverter block 57 to make it stationary. When the purified liquid in the supply tank 41 flows into the interior of the purification component 42, the diverter block 57 guides it, and the purified liquid is dispersed through the arc surface of its own outer wall. And it flows downward along the outer wall of the diverter block 57. At this time, the purification component 42 drives the purified liquid to rotate and continuously flush the filter plate 55. Through the above cooperation, the filter plate 55 relies on the filter holes on its own outer wall to continuously disturb and refine the purified liquid, which is convenient for the purified liquid to be fully mixed with other additives. The filter plate 55 intercepts the sediment in the purified liquid, while ensuring that the desulfurization and denitrification effects are not affected. At the same time, it effectively avoids the sediment from clogging the spray port of the spray component 43, preventing the spray liquid from being difficult to spray. When the purification component 42 rotates, it drives the cam 58 to rotate.

[0028] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-adhesion device 6; The anti-adhesion device 6 includes a sliding plate 61, a round wheel 62 and a slotted arc plate 63. The sliding plate 61 is slidably installed on the outer wall of the filter plate 55 near the axis of the fixed rod 51. The top of the round wheel 62 is fixedly installed on the bottom of the sliding plate 61. The slotted arc plate 63 is fixedly installed between the outer wall of the sliding plate 61 and the outer wall of the filter plate 55 near the axis of the fixed rod 51. The slotted arc plate 63 is elastic. Through the above cooperation, the sliding plate 61 is used to crush the sediment attached to the surface of the filter plate 55, so that the sediment is conveniently re-mixed with the purified liquid, avoiding the sediment from clogging the filter holes of the filter plate 55 and making it difficult to flush the purified liquid. At the same time, when the slotted arc plate 63 is deformed, the flushing force of the purified liquid around the filter plate 55 is increased, thereby improving the mixing uniformity of the purified liquid and other additives.

[0029] The anti-adhesion device 6 also includes a T-shaped arc block 64, a hinged plate 65, a transmission plate 66, a penetration rod 67 and a semicircular block 68. The T-shaped arc block 64 is fixedly installed on the inner wall of the sliding plate 61 near the side of the fixed rod 51, the hinged plate 65 is hinged between the top of the T-shaped arc block 64 and the bottom edge of the diverter block 57, the bottom of the transmission plate 66 is hinged to the outer wall of the hinged plate 65 near the side of the fixed rod 51, the bottom of the penetration rod 67 is penetrated by a spring and slidably installed inside the fixed rod 51, and the bottom of the semicircular block 68 is fixedly installed on the top of the penetration rod 67. Through the above cooperation, the diverter block 57 and the semicircular block 68 are used to accelerate the surging frequency of the purified liquid around itself, so as to ensure that the purified liquid can fully combine with the sediment before being discharged from the purification component 42 to avoid reducing the purification effect of the purified liquid. At the same time, during the sliding process of the T-shaped arc block 64, the concave surface of itself guides and pushes away the purified liquid flushed by the filter hole plate 55 for a second time, so as to prevent the filter hole plate 55 from reciprocatingly flushing the purified liquid around itself, thereby reducing the flushing effect.

[0030] The bottom of the T-shaped arc block 64 contacts the top of the filter plate 55 , and the bottom of the semicircular block 68 is hinged to the top of the transmission plate 66 .

[0031] When in use, the outer wall of the cam 58 continuously contacts the outer wall of the round wheel 62 when the cam 58 rotates. Under the contact of the cam 58, the outer wall of the round wheel 62 continuously slides along the outer wall of the cam 58. Thus, the cam 58 enables the round wheel 62 to move along its own outer wall toward the fixed rod 51 and reset. The round wheel 62 drives the sliding plate 61 to slide synchronously along the outer wall of the filter plate 55. When the sliding plate 61 slides, the slotted arc plate 63 is squeezed to deform synchronously and reset. The elasticity of the slotted arc plate 63 causes the outer wall of the round wheel 62 to always fit closely to the cam 55. 8 outer wall, through the above cooperation, the sliding plate 61 is used to crush the sediment attached to the surface of the filter plate 55, so that the sediment is re-mixed in the purified liquid, and the sediment is prevented from clogging the filter holes of the filter plate 55 and making it difficult to flush the purified liquid. At the same time, when the slotted arc plate 63 is deformed, the flushing force of the purified liquid around the filter plate 55 is increased, and the mixing uniformity of the purified liquid and other additives is improved; the sliding plate 61 slides toward the direction close to the fixed rod 51 and resets, driving the T-shaped arc block 64 to move synchronously, and the T-shaped arc block 64 pulls The hinged plate 65 moves at the same time. The top of the hinged plate 65 is restricted by the diverter block 57, causing its own hinge axis to start to rotate. The hinged plate 65 rotates away from the fixed rod 51 with the hinge axis as the axis. The hinged plate 65 drives the transmission plate 66 to move synchronously. The hinge axis of the transmission plate 66 starts to rotate and pulls the semicircular block 68 to move downward. The semicircular block 68 presses the through rod 67 to slide downward inside the fixed rod 51. After that, the through rod 67 pushes the semicircular block 68 to quickly reset when the spring resets. During the movement, the purified liquid under the shunt block 57 is disturbed upward. Through the above cooperation, the shunt block 57 and the semicircular block 68 are used to accelerate the surging frequency of the purified liquid around itself, so as to ensure that the purified liquid can fully combine with the sediment before being discharged from the purification component 42 to avoid the reduction of the purification effect of the purified liquid. At the same time, during the sliding process of the T-shaped arc block 64, the purified liquid flushed by the filter hole plate 55 is guided and pushed away for the second time through its own concave surface, so as to prevent the filter hole plate 55 from reciprocatingly flushing the purified liquid around itself, thereby reducing the flushing effect.

[0032] A denitration and desulfurization method for a flue gas denitration and desulfurization scrubbing device comprises the following steps: S1: Inject purification liquids of different components into the supply box 41 through multiple supply holes on the top of the supply box 41. At this time, the supply box 41 is kept stable by the limit of the fixed plate 21, and the fixed frame 2 limits the fixed plate 21; S2: When the device body 1 is installed inside the smoke outlet pipe through the installation component on its outer wall for use, the heating component 11 inside the interlayer of the device body 1 is started, and the heat emitted by the heating component 11 increases the internal temperature of the device body 1; S3: The purification liquid flows into the purification component 42 through the supply box 41, and the motor 31 is started. When the output end of the motor 31 rotates, the supply box 41 is driven to rotate, and the supply box 41 drives the purification component 42 to rotate. The purification component 42 uses the centrifugal force of the rotation to rotate the purification liquid inside itself through the spraying component 43 into the inside of the device body 1 and adhere to its inner wall to purify the flue gas; S4: When the purification component 42 rotates, it drives the horizontal plate 44 to rotate, and the horizontal plate 44 drives the scraper 45 to rotate and scrape along the inner wall of the device body 1. At the same time, the scraper 45 drives the spoiler 46 to rotate and disturb inside the device body 1, and the spoiler 46 drives the vertical rod 47 to move synchronously, and the vertical rod 47 drives the fan plate 48 to revolve.
