Technical Field

[0001] This invention belongs to the field of sulfurized flue gas treatment technology, and particularly relates to an integrated equipment for turbulent enhanced desulfurization and denitrification of sulfurized flue gas. Background Technology

[0002] The emission of sulfides and nitrogen oxides from industrial flue gas is a core issue in air pollution control, driving the evolution of desulfurization and denitrification technologies from early stepwise treatment to integrated and synergistic governance. Early technologies often operated desulfurization and denitrification equipment independently, resulting in problems such as equipment redundancy, large footprint, and high energy consumption. With increasingly stringent environmental requirements, integrated technologies have become a research hotspot. Among them, wet integrated desulfurization and denitrification technology is widely used due to its fast reaction rate and high removal efficiency. Traditional wet desulfurization and denitrification technologies typically employ a spray tower structure, spraying flue gas treatment liquid to remove SO2 and NO. x Synchronous removal.

[0003] However, existing flue gas desulfurization and denitrification devices still have the following shortcomings in use: First, the gas-liquid interface renewal rate is insufficient. The gas-liquid contact area of ​​traditional spray towers is limited to the surface of the droplets, making it difficult to overcome the mass transfer resistance of the liquid film. Second, the power system has high energy consumption and relies heavily on electric or pneumatic actuators, failing to fully utilize the fluid's own kinetic energy. Summary of the Invention

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The integrated equipment for enhanced turbulent desulfurization and denitrification of sulfurized flue gas includes a purification tower with an inlet pipe and an exhaust pipe, and further includes: a spraying mechanism for spraying flue gas treatment liquid into the purification tower; a separating mechanism including: a rotating plate rotatably connected to the inner wall of the purification tower, with multiple first through slots for receiving the flue gas treatment liquid sprayed by the spraying mechanism; a fixed plate fixedly connected to the inner wall of the purification tower, with its top surface contacting the bottom surface of the rotating plate, and multiple second through slots matching the first through slots, the second through slots containing mesh cylinders for holding honeycomb packing; and an adjusting mechanism for using the liquid flow power of the flue gas treatment liquid transported by the spraying mechanism to drive the rotating plate to rotate, so that the multiple first through slots and multiple second through slots are intermittently connected.

[0006] Preferably, it also includes: a support frame, which is fixedly connected to the purification tower; and a drain pipe, which is installed on the bottom surface of the purification tower and has a valve on it.

[0007] Preferably, the spraying mechanism includes: a liquid storage tank, mounted on the support frame, for holding flue gas treatment liquid; a micro-nano bubble generator, mounted on the top surface of the liquid storage tank; a delivery pump, mounted on the support frame, with its suction pipe extending into the liquid storage tank; a thick pipe, connected to the delivery pipe of the delivery pump; and a bend pipe, installed through the top surface of the purification tower, with its upper end connected to the thick pipe and its lower end rotatably mounted with an atomizing nozzle, the atomizing nozzle being fixedly fitted with a second pulley.

[0008] Preferably, the adjusting mechanism includes: a gear ring, which is fixedly connected to the top surface of the rotating plate via multiple connecting blocks; a vertical rod, which is rotatably connected to the purification tower and the coarse pipe; a gear, which is installed at the lower end of the vertical rod and meshes with the gear ring; and a first fan blade, which is located inside the coarse pipe and is fixedly connected to the upper end of the vertical rod.

[0009] Preferably, the adjustment mechanism further includes: a first pulley, fixedly sleeved on the vertical rod; a transmission belt, sleeved on the first pulley and the second pulley; and a butterfly baffle, installed on the vertical rod, with its bottom surface in contact with the top surface of the exhaust pipe.

[0010] Preferably, it further includes a filtration mechanism, which includes: a filter plate installed inside the air inlet pipe; a mounting plate installed inside the air inlet pipe; a crossbar rotatably connected to the filter plate and the mounting plate; a second fan blade installed at the end of the crossbar near the purification tower; a second bevel gear fixedly sleeved on the crossbar; and a cleaning brush installed on the crossbar, contacting the side of the filter plate away from the mounting plate.

[0011] Preferably, the filtration mechanism further includes: a motor mounted on the support frame, the power output shaft of which extends into the air intake pipe and is rotatably connected to the air intake pipe; and a first bevel gear mounted on the power output shaft of the motor and meshing with the second bevel gear.

[0012] Preferably, the filtration mechanism further includes: a mounting box, installed on the side of the mounting plate away from the filter plate, wherein both the first bevel gear and the second bevel gear are located inside the mounting box.

[0013] Preferably, the flue gas treatment liquid is a mixture of sodium hypochlorite and sodium hydroxide.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. The integrated desulfurization and denitrification equipment for turbulent enhanced desulfurization of flue gas in this invention, through the setting of a liquid spraying mechanism, a separating mechanism, and an adjusting mechanism, allows the adjusting mechanism to drive the rotating plate to rotate when the liquid spraying mechanism is running. This intermittently connects the first channel with the second channel of the fixed plate, allowing the flue gas treatment liquid received by the rotating plate to enter the mesh cylinder through the channel and form a liquid film on the surface of the packing. When the first channel and the second channel are connected, the flue gas is forced to pass through the gaps in the filter media and fully contact the liquid film. When the first channel and the second channel are staggered, the residence time of the flue gas under the fixed plate can be extended, improving the treatment effect of the flue gas. Furthermore, the flue gas is buffered and slowed down when passing through the gaps in the honeycomb packing, extending the contact time and further improving the treatment effect of the flue gas.

[0015] 2. The spraying mechanism in this invention comprises a storage tank, a micro / nano bubble generator, a delivery pump, a thick pipe, a curved pipe, and an atomizing nozzle. The micro / nano bubble generator produces microbubbles within the storage tank. These microbubbles are then mixed with the flue gas treatment liquid via the delivery pump and sprayed out through the atomizing nozzle. The high specific surface area and strong interfacial activity of the microbubbles enhance the droplet's action on SO2 and NO. x It has a strong adsorption capacity; and the micro-jet that breaks up the bubbles enhances the mass transfer inside the droplets, solving the problem of the dead zone of droplet reaction in traditional atomization and improving the treatment effect on sulfurized flue gas.

[0016] 3. The regulating mechanism in this invention, by setting a butterfly baffle, can periodically block the exhaust pipe opening, so that the sulfurized flue gas forms a pulse flow in the tower, which enhances the mixing of the gas and liquid phases and prolongs the residence time of the sulfurized flue gas in the purification tower, thereby improving the treatment effect of the sulfurized flue gas.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention.

[0022] This invention is described in detail with reference to the accompanying drawings. When detailing the embodiments of this invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not to scale. Furthermore, the accompanying drawings are merely examples and should not be construed as limiting the scope of protection of this invention. In actual fabrication, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0023] Furthermore, it should be noted in the description of this invention that the terms "first," "second," or "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] Unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" in this invention should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; similarly, they can refer to mechanical connections, electrical connections, or direct connections, or indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] Example 1: As Figure 1 , Figure 4 and Figures 7-9 As shown, the integrated equipment for enhanced desulfurization and denitrification of sulfurized flue gas by turbulence includes a purification tower 101, on which an inlet pipe 102 and an exhaust pipe 105 are installed. The integrated equipment for enhanced desulfurization and denitrification of sulfurized flue gas by turbulence also includes a liquid spraying mechanism 110, a separation mechanism 120 and an adjustment mechanism 130.

[0026] The spraying mechanism 110 is used to spray flue gas treatment liquid into the purification tower 101. The flue gas treatment liquid is a mixture of sodium hypochlorite and sodium hydroxide, with a sodium hypochlorite concentration of 0.5-2 mol / L and a sodium hydroxide concentration of 1-3 mol / L, and a pH value of 10-12. Sodium hypochlorite (NaClO), as a strong oxidant, can oxidize NO to NO2 and NO3. - Sodium hydroxide (NaOH) provides an alkaline environment that can absorb SO2 (generating Na2SO3 / Na2SO4) and oxidized nitrogen oxides (generating NaNO2 or NaNO3). Specifically, SO2 reacts with NaOH (alkaline medium) to produce sodium sulfite: the chemical reaction formula is: SO2 + 2NaOH = Na2SO3 + H2O; Sodium hypochlorite (NaClO) further oxidizes sodium sulfite to the more stable sodium sulfate (avoiding the secondary release of SO2 from sulfite): the chemical reaction is: Na2SO3 + NaClO = Na2SO4 + NaCl. This achieves the desulfurization effect.

[0027] NO in flue gas x The primary component is NO (70%-90%), which is poorly soluble in water and chemically inert. It must first be oxidized to higher oxidation states of nitrogen oxides (such as NO2 and N2O5) before it can be absorbed by the alkaline solution. Sodium hypochlorite can act as an oxidant under alkaline conditions to achieve this process. In the oxidation stage, NaClO in an alkaline environment generates ClO, a highly oxidizing agent. - oxidize NO to NO2 or NO3 - The chemical reaction formula is: 2NO + 3ClO - +2OH - =2NO3 - +3Cl - +H2O (oxidized to nitrate); NO+ClO - +2OH - =NO2 - +Cl - +H2O (oxidized to nitrite, a minor reaction).

[0028] During the absorption phase: NO2 and NO3 generated by oxidation - NO2 - It reacts with NaOH to produce nitrate (NaNO3) and nitrite (NaNO2). The chemical reaction formula is: NO2 + 2NaOH = NaNO3 + NaNO2 + H2O; NO3 - +Na⁺=NaNO₃ (ion combination in solution); thus achieving the effect of denitrification.

[0029] The separating mechanism 120 includes a rotating plate 121 and a fixed plate 123. The rotating plate 121 is rotatably connected to the inner wall of the purification tower 101. Multiple first through slots 122 are provided through the rotating plate 121, which is used to receive the flue gas treatment liquid sprayed by the spraying mechanism 110. The fixed plate 123 is fixedly connected to the inner wall of the purification tower 101. The top surface of the fixed plate 123 contacts the bottom surface of the rotating plate 121. Multiple second through slots 124 matching the first through slots 122 are provided through the fixed plate 123. A mesh cylinder 125 for holding honeycomb packing is installed in the second through slot 124.

[0030] The regulating mechanism 130 is used to drive the rotating plate 121 to rotate by using the liquid flow power of the liquid spraying mechanism 110 to deliver the flue gas treatment liquid, so that the multiple first channels 122 are intermittently connected to the multiple second channels 124.

[0031] Specifically, by activating the spraying mechanism 110, flue gas treatment liquid is sprayed into the purification tower 101. When the spraying mechanism 110 delivers the sprayed flue gas treatment liquid, the adjusting mechanism 130 drives the rotating plate 121 to rotate, thereby intermittently connecting multiple first channels 122 and multiple second channels 124. When the first channel 122 is connected to the second channel 124, the flue gas treatment liquid on the rotating plate 121 will enter the second channel 124 through the first channel 122. The flue gas treatment liquid will contact the honeycomb packing in the mesh cylinder 125 and form a uniform liquid film on the surface of the honeycomb packing.

[0032] The sulfurized flue gas to be treated is then conveyed into the inlet pipe 102, allowing it to enter the treatment tower. The flue gas is positioned below the fixed plate 123. When the first channel 122 and the second channel 124 are connected, the flue gas passes through the mesh cylinder 125 filled with honeycomb packing, the first channel 122, and the second channel 124, entering above the rotating plate 121. As the flue gas passes through the mesh cylinder 125, it must pass through the gaps in the packing material, ensuring sufficient contact between the flue gas and the liquid film on the honeycomb packing, significantly improving desulfurization efficiency. In this embodiment, the honeycomb packing is made of acid and alkali resistant ceramic material, with hexagonal channels, a pore diameter of 5-10 mm, and a pore density of 30-50 pores / cm². 2 Specific surface area ≥200m² 2 / m 3 Ensure that the liquid film forms uniformly and the gas resistance is ≤500Pa.

[0033] When the sulfurized flue gas moves above the rotating plate 121, it comes into contact with the flue gas treatment liquid sprayed by the spraying mechanism 110, thereby allowing the flue gas treatment liquid to treat the sulfurized flue gas.

[0034] When the spraying mechanism 110 sprays the flue gas treatment liquid, the adjusting mechanism 130 drives the rotating plate 121 to rotate, so that multiple first channels 122 and multiple second channels 124 are intermittently connected, thereby increasing the residence time of the sulfurized flue gas under the fixed plate 123 and further improving the desulfurization effect.

[0035] In addition, the honeycomb packing inside the mesh cylinder 125 can also buffer the airflow impact, prevent the atomized flue gas treatment liquid from being directly carried away by the high-speed sulfurized flue gas, reduce the loss of absorbent liquid, and slow down the speed at which the sulfurized flue gas is discharged from the purification tower 101, thereby increasing the time the sulfurized flue gas stays in the purification tower 101.

[0036] like Figure 1 and Figure 4As shown, the integrated equipment for enhanced turbulent desulfurization and denitrification of sulfurized flue gas also includes a support frame 100 and a drain pipe 103. The support frame 100 is fixedly connected to the purification tower 101; the support frame 100 consists of two rings, multiple support columns, and a base plate. Both rings are fixedly connected to the purification tower 101, the multiple support columns are fixedly connected to the two rings, and the lower ends of the multiple support columns are fixedly connected to the base plate. The drain pipe 103 is installed on the bottom surface of the purification tower 101, and a valve 104 is installed on the drain pipe 103.

[0037] Specifically, the support frame 100 facilitates the support of the purification tower 101. The drain pipe 103 and valve 104 facilitate the discharge of the flue gas treatment liquid from the bottom of the purification tower 101.

[0038] like Figure 1 and Figures 4-6 As shown, the liquid spraying mechanism 110 includes a liquid storage tank 111, a micro / nano bubble generator 112, a delivery pump 113, a thick pipe 114, and a bend pipe 115. The liquid storage tank 111 is mounted on the support frame 100 and is used to hold the flue gas treatment liquid. The micro / nano bubble generator 112 is mounted on the top surface of the liquid storage tank 111. The micro / nano bubble generator 111 is an ultrasonic type with a power of 500-1000W. It is connected to the bottom of the liquid storage tank 111 via a pipe, with an inlet pressure of 0.2-0.5MPa to ensure that the bubble diameter is stable at 50-500nm. The micro / nano bubble generator 112 is a mature existing technology; its specific structure and working principle will not be described in detail here. The delivery pump 113 is mounted on... On the support frame 100, the feed pipe of the delivery pump 113 extends into the liquid storage tank 111. The delivery pump 113 is a water-air dual-purpose pump. The thick pipe 114 is connected to the feed pipe of the delivery pump 113. The bent pipe 115 is installed through the top surface of the purification tower 101. The upper end of the bent pipe 115 is connected to the thick pipe 114. The lower end of the bent pipe 115 is rotatably installed with an atomizing nozzle 116. A second pulley 117 is fixedly sleeved on the atomizing nozzle 116. The atomizing nozzle 116 is a high-pressure nozzle with a working pressure of 0.5-1.0MPa and an atomized particle size of 50-200μm.

[0039] Specifically, by activating the micro-nano bubble generator 112, microbubbles (50-500nm in diameter) are created in the storage tank 111. Then, by activating the delivery pump 113, the flue gas treatment liquid and microbubbles in the storage tank 111 are transported to the coarse pipe 114, and then the flue gas treatment liquid and microbubbles are transported to the atomizing nozzle 116 through the bend pipe 115. The atomizing nozzle 116 sprays out the flue gas treatment liquid and microbubbles. The flue gas treatment liquid will form atomized droplets with the microbubbles. When the sulfurized flue gas rises countercurrently from the bottom of the purification tower 101, the sulfurized flue gas will collide with the atomized droplet group from top to bottom. Because the microbubbles are much smaller than the droplets, they can form a gas-liquid interface network inside and on the surface of the droplets, which greatly increases the gas-liquid contact area per unit volume. The contact area is 5-10 times that of direct spraying.

[0040] Meanwhile, the strong interfacial activity of micro- and nano-bubbles can enhance the adsorption capacity of atomized droplets for pollutants in sulfurized flue gas. At the same time, the local micro-jets released when the bubbles burst can enhance the internal mass transfer of the droplets, solving the problem of dead zones in the internal reaction of droplets in traditional atomization.

[0041] like Figure 7 As shown, the adjustment mechanism 130 includes a gear ring 131, a vertical rod 133, a gear 134, and a first fan blade 135.

[0042] The gear ring 131 is fixedly connected to the top surface of the rotating plate 121 via multiple connecting blocks 132; the vertical rod 133 is rotatably connected to the purification tower 101 and the coarse pipe 114; the gear 134 is installed at the lower end of the vertical rod 133, meshing with the gear ring 131, and both the gear 134 and the gear ring 131 are coated with a polytetrafluoroethylene anti-corrosion layer; the first fan blade 135 is located inside the coarse pipe 114, and is fixedly connected to the upper end of the vertical rod 133. The first fan blade 135 adopts a streamlined design, and its blade area is 30% of the cross-sectional area of ​​the coarse pipe 114, which facilitates increased liquid flow impact force.

[0043] To further improve the stability of the regulating mechanism 130, a reduction gearbox (reduction ratio 1:3) can be installed between the vertical rod 133 and the gear 134 to reduce the load on the fluid drive.

[0044] Specifically, when the flue gas treatment liquid passes through the coarse pipe 114, it will drive the first fan blade 135 to rotate, which in turn drives the vertical rod 133 to rotate, which in turn drives the gear 134 to rotate. Since the gear 134 and the gear ring 131 mesh, when the gear 134 rotates, it will drive the gear ring 131 to rotate, which in turn drives the rotating plate 121 to rotate.

[0045] like Figure 4 , Figure 5 and Figure 7As shown, the adjusting mechanism 130 also includes a first pulley 136, a transmission belt 137, and a butterfly baffle 138. The first pulley 136 is fixedly sleeved on the vertical rod 133; the transmission belt 137 is sleeved on the first pulley 136 and the second pulley 117; the butterfly baffle 138 is installed on the vertical rod 133, and the bottom surface of the butterfly baffle 138 contacts the top surface of the exhaust pipe 105.

[0046] Specifically, when the vertical rod 133 rotates, it drives the second pulley 117 to rotate through the first pulley 136 and the transmission belt 137, which in turn drives the atomizing nozzle 116 to rotate. The rotating atomizing nozzle 116 can evenly distribute the droplets into the treatment space of the purification tower 101, so that the sulfurized flue gas can fully collide with the absorbent liquid during the flow process, avoiding excessively high local pollutant concentrations that are not absorbed, thereby improving the overall removal efficiency.

[0047] Furthermore, when the vertical rod 133 rotates, it will also drive the butterfly baffle 138 to rotate. The rotating butterfly baffle 138 will intermittently block the opening of the exhaust pipe 105, causing the exhaust pipe 105 to exhaust intermittently, thereby prolonging the residence time of the sulfurized flue gas in the purification tower 101, and thus improving the treatment effect of the sulfurized flue gas.

[0048] Working principle: In actual use, the pipeline for conveying sulfurized flue gas is connected to the air inlet pipe 102.

[0049] Next, by starting the micro-nano bubble generator 112, microbubbles are created in the liquid storage tank 111; then by starting the delivery pump 113, the flue gas treatment liquid and microbubbles in the liquid storage tank 111 are delivered to the coarse pipe 114, and then the flue gas treatment liquid and microbubbles are delivered to the atomizing nozzle 116 through the bend pipe 115, so that the atomizing nozzle 116 sprays out the flue gas treatment liquid and microbubbles, and the flue gas treatment liquid will form atomized droplets with the microbubbles.

[0050] Furthermore, when the spraying mechanism 110 delivers and sprays the flue gas treatment liquid, it drives the first fan blade 135 to rotate, which in turn drives the vertical rod 133 to rotate, which in turn drives the gear 134 to rotate. Since the gear 134 meshes with the gear ring 131, when the gear 134 rotates, it drives the gear ring 131 to rotate, which in turn drives the rotating plate 121 to rotate. This causes the multiple first through slots 122 and multiple second through slots 124 to be intermittently connected. When the first through slot 122 is connected to the second through slot 124, the flue gas treatment liquid on the rotating plate 121 will enter the second through slot 124 through the first through slot 122. The flue gas treatment liquid will come into contact with the honeycomb packing in the mesh cylinder 125 and form a liquid film on the surface of the honeycomb packing.

[0051] The sulfurized flue gas to be treated is then transported into the inlet pipe 102, so that the sulfurized flue gas enters the treatment tower through the inlet pipe 102. The sulfurized flue gas will be below the fixed plate 123. When the first channel 122 and the second channel 124 are connected, the sulfurized flue gas will pass through the mesh cylinder 125 containing honeycomb packing, the first channel 122 and the second channel 124 and enter the area above the rotating plate 121. When the sulfurized flue gas passes through the mesh cylinder 125, it needs to pass through the gaps in the packing, so that the sulfurized flue gas can fully contact the liquid film on the honeycomb packing, which greatly improves the desulfurization efficiency.

[0052] When the sulfurized flue gas moves above the rotating plate 121, it collides with the atomized droplets descending from above, thereby treating the sulfur-containing gas. Furthermore, the micro-nano bubbles in the atomized droplets, being much smaller than the droplets, can form a gas-liquid interface network inside and on the surface of the droplets, significantly increasing the gas-liquid contact area per unit volume and further improving the treatment effect on the sulfurized flue gas.

[0053] Furthermore, when the vertical rod 133 rotates, it will drive the second pulley 117 to rotate through the first pulley 136 and the transmission belt 137, which in turn drives the atomizing nozzle 116 to rotate. The rotating atomizing nozzle 116 can evenly distribute the droplets into the treatment space of the purification tower 101, so that the sulfurized flue gas can fully collide with the absorbent liquid during the flow process, avoiding excessively high local pollutant concentrations that are not absorbed, thereby improving the overall removal efficiency.

[0054] Finally, the treated sulfurized flue gas is discharged through the exhaust pipe 105. When the vertical rod 133 rotates, it also drives the butterfly baffle 138 to rotate. The rotating butterfly baffle 138 will intermittently block the opening of the exhaust pipe 105, causing the exhaust pipe 105 to exhaust intermittently, thereby prolonging the residence time of the sulfurized flue gas in the purification tower 101 and thus improving the treatment effect of the sulfurized flue gas.

[0055] When the spraying mechanism 110 sprays the flue gas treatment liquid, the adjusting mechanism 130 drives the rotating plate 121 to rotate, so that multiple first channels 122 and multiple second channels 124 are intermittently connected, thereby increasing the residence time of the sulfurized flue gas under the fixed plate 123 and further improving the desulfurization effect.

[0056] In addition, the honeycomb packing inside the mesh cylinder 125 can also buffer the airflow impact, prevent the atomized flue gas treatment liquid from being directly carried away by the high-speed sulfurized flue gas, reduce the loss of absorbent liquid, and slow down the speed at which sulfurized flue gas is discharged from the purification tower 101, thereby increasing the time of sulfurized flue gas in the purification tower 101 and improving the treatment effect of sulfurized flue gas.

[0057] Example 2: Figure 2 and Figure 3 As shown, while all other parts are the same as in Example 1, the difference between this example and Example 1 is that: The integrated equipment for enhanced desulfurization and denitrification of sulfurized flue gas also includes a filter mechanism 140, which includes a filter plate 141, a mounting plate 142, a crossbar 144, a second fan blade 145, a second bevel gear 146, and a cleaning brush 149.

[0058] The filter plate 141 is installed inside the air inlet pipe 102; the mounting plate 142 is installed inside the air inlet pipe 102; the crossbar 144 is rotatably connected to the filter plate 141 and the mounting plate 142; the second fan blade 145 is installed at one end of the crossbar 144 near the purification tower 101; the second bevel gear 146 is fixedly sleeved on the crossbar 144; the cleaning brush 149 is installed on the crossbar 144, and the cleaning brush 149 is an adjustable nylon brush, which contacts the side of the filter plate 141 away from the mounting plate 142.

[0059] Specifically, by setting up the filter plate 141, sulfur-containing flue gas passing through the intake pipe 102 can be filtered to remove particulate matter from the flue gas. When the crossbar 144 rotates, it will drive the second fan blade 145 to rotate. The second fan blade 145 will also drive the flue gas to move in a circular motion, forming a shear force with the axial mainstream, tearing the large-scale flue gas cloud into small-scale vortices, and finally forming turbulence. The second fan blade 145 is composed of multiple spiral fan blades with an angle of 30°.

[0060] Furthermore, when the crossbar 144 rotates, it will also drive the cleaning brush 149 to rotate, so that the cleaning brush 149 cleans the filter plate 141, thereby preventing debris from clogging the filter plate 141 and affecting the filtration efficiency.

[0061] like Figure 2 and Figure 3 As shown, the filter mechanism 140 also includes a motor 147 and a first bevel gear 148: the motor 147 is mounted on the support frame 100, and the power output shaft of the motor 147 extends into the air intake pipe 102 and is rotatably connected to the air intake pipe 102; the first bevel gear 148 is mounted on the power output shaft of the motor 147, and the first bevel gear 148 meshes with the second bevel gear 146.

[0062] Specifically, when the motor 147 is running, it will drive the first bevel gear 148 to rotate, which in turn will mesh with and drive the second bevel gear 146 to rotate, which in turn will drive the crossbar 144 to rotate.

[0063] like Figure 2 and Figure 3 As shown, the filter mechanism 140 also includes a mounting box 143. The mounting box 143 is mounted on the side of the mounting plate 142 away from the filter plate 141, and the first bevel gear 148 and the second bevel gear 146 are both located inside the mounting box 143. The crossbar 144 and the power output shaft of the motor 147 are both rotatably connected to the mounting box 143.

[0064] Specifically, by setting up the mounting box 143, the sulfurized flue gas can be prevented from directly contacting the first bevel gear 148 and the second bevel gear 146, thus avoiding affecting the transmission of the first bevel gear 148 and the second bevel gear 146.

[0065] Working principle: In actual use, when sulfurized flue gas is conveyed into the intake pipe 102, the filter plate 141 can filter the sulfur-containing flue gas passing through the intake pipe 102, filtering out the particulate matter in the flue gas. At the same time, the motor 147 is started, driving the first bevel gear 148 to rotate, which in turn drives the second bevel gear 146 to rotate, which in turn drives the crossbar 144 to rotate. When the crossbar 144 rotates, it drives the second fan blade 145 to rotate. The second fan blade 145 also drives the flue gas to make a circular motion, forming a shearing force with the axial mainstream, tearing the large-scale flue gas cloud into small-scale vortices, and finally forming turbulence.

[0066] Furthermore, when the crossbar 144 rotates, it will also drive the cleaning brush 149 to rotate, so that the cleaning brush 149 cleans the filter plate 141, thereby preventing debris from clogging the filter plate 141 and affecting the filtration efficiency.
