Description

Technical Field

[0001] This application relates to the field of spray tower technology for waste gas treatment, and in particular to a high-efficiency waste gas treatment spray tower. Background Technology

[0002] In modern industrial production, numerous industries generate large quantities of waste gas containing various pollutants. Taking the chemical and pharmaceutical industries as examples, organic solvents such as dimethylformamide (DMF) are used in the processing of specific parts or the manufacturing of products. During the operation of these parts processing equipment, devices such as reaction vessels and distillation towers inevitably release waste gas containing pollutants such as DMF. This waste gas has a complex composition, containing not only organic waste gas from the volatilization of organic solvents but also potentially other harmful gases and particulate matter generated during the production process.

[0003] Traditional waste gas treatment equipment, especially conventional waste gas spray towers, has many shortcomings when dealing with such complex waste gases. Traditional spray towers typically only have a single spray device and a packing layer. This simple structure means that the waste gas only comes into brief contact with the spray liquid as it flows through the tower. Furthermore, the spray liquid often flows unevenly within the packing layer, and waste gas entering from the bottom tends to accumulate. This results in insufficient contact between the waste gas and the spray liquid, low treatment efficiency, and poor demisting effect, leaving the exhaust gas with a significant amount of droplets and pollutant residues, making it difficult to meet environmental protection requirements and the need for high-efficiency treatment. Summary of the Invention

[0004] In order to achieve the goal of efficient treatment of waste gas by spray tower, this application provides a high-efficiency waste gas treatment spray tower.

[0005] The high-efficiency waste gas treatment spray tower provided in this application adopts the following technical solution:

[0006] A high-efficiency waste gas treatment spray tower includes a tower base, a tower body fixedly installed on the upper surface of the tower base, an air inlet fixedly installed on one side of the tower body, and an air outlet cap fixedly installed on the top of the tower body. A first spray plate, a packing assembly, and a second spray plate are sequentially arranged from bottom to top within the tower body. The first spray plate, the packing assembly, and the second spray plate are all fixedly connected to the tower body. A liquid storage tank is fixedly installed in the tower base, and a supply assembly is also installed on the tower base to supply liquid from the liquid storage tank to the first and second spray plates. A fan impeller is also installed at the bottom of the tower base, and a drive assembly for driving the fan impeller to rotate is also fixedly installed in the tower base.

[0007] By adopting the above technical solution, the tower base ensures stable vertical placement of the tower body, while the inlet and outlet caps ensure a stable flow of waste gas into the tower. After treatment, the gas is discharged through the outlet caps. The first spray plate, packing assembly, and second spray plate are sequentially arranged from bottom to top within the tower body, achieving efficient sequential treatment of the waste gas. The first spray plate directly reacts with the waste gas through atomized liquid, while the packing assembly and second spray plate work together to ensure sufficient reaction between the waste gas and the treatment liquid within the packing. The impeller accelerates the flow of waste gas within the tower, ensuring full contact between the waste gas and the spray liquid and improving treatment efficiency. Simultaneously, the liquid storage tank and supply assembly guarantee the continuous circulation of the spray liquid, ensuring continuous waste gas treatment.

[0008] Optionally, the air outlet cap includes a converging tower cover, a wire mesh demister, and an air outlet pipe. The converging tower cover is sealed and fixed to the top of the tower body, the wire mesh demister is fixedly installed in the converging tower cover, and the air outlet pipe is vertically fixed to the head of the converging tower cover.

[0009] By adopting the above technical solution, the converging tower cover in the exhaust cap can concentrate the treated exhaust gas, allowing it to be discharged more centrally through the exhaust pipe. The wire mesh demister can effectively remove liquid droplets carried in the exhaust gas, preventing them from being discharged with the exhaust gas, thus improving the quality of exhaust gas emissions and reducing secondary pollution to the environment.

[0010] Optionally, the first spray plate includes an annular seat, a spiral tube, and several sets of dividing ring plates with different diameters. The spiral tube is fixedly installed on the upper end face of the annular seat, and several atomizing nozzles are evenly installed on the lower end face of the spiral tube. Several dividing ring plates are coaxially arranged, and several dividing ring plates are all fixedly installed on the lower end of the annular seat.

[0011] By adopting the above technical solution, the spiral tube and atomizing nozzle design of the first spray plate enable the spray liquid to be evenly sprayed into the tower in an atomized form, increasing the contact area between the spray liquid and the waste gas and improving the absorption effect of pollutants in the waste gas. The partition ring plate can separate and guide the waste gas, facilitating efficient spraying and contact reaction by the atomizing nozzles in different zones, making the waste gas more evenly distributed in the tower and further enhancing the treatment effect.

[0012] Optionally, the annular seat includes an outer ring frame, connecting ear plates, and a cross bracket for mounting the spiral tube and the dividing ring plate. The connecting ear plates are symmetrically fixed on both sides of the outer side of the outer ring frame, and the cross bracket is fixedly installed in the outer ring frame.

[0013] By adopting the above technical solution, the outer ring frame, connecting ear plate, and cross bracket structure of the annular seat provide a stable installation foundation for the spiral tube and the partition ring plate, ensuring the stability of the first spray plate. The connecting ear plate facilitates the connection and fixation of the first spray plate to the tower body, while the cross bracket rationally allocates the installation space for the spiral tube and the partition ring plate, making the structure more compact.

[0014] Optionally, the packing assembly includes an annular shell, a top packing frame, and a bottom packing frame. The annular shell is fixedly installed in the tower body, the top packing frame is positioned above the bottom packing frame, and both the top and bottom packing frames are rotatably installed in the annular shell.

[0015] By adopting the above technical solution, the top and bottom packing frames of the packing assembly are rotatably installed in the annular shell, allowing the packing to rotate under the action of the exhaust gas flow. This increases the contact opportunity between the packing and the exhaust gas, improving the adsorption and filtration efficiency of the packing for pollutants in the exhaust gas. Simultaneously, the rotation of the top and bottom packing frames ensures that the treatment liquid sprayed from the top enters the packing more evenly.

[0016] Optionally, a crossbar seat is installed on the inner side of the annular shell. One end of the crossbar seat is fixedly connected to the annular shell, and a concave frame seat is fixedly installed on the other end of the crossbar seat. A horizontal shaft is rotatably installed in the middle of the concave frame seat, and vertical shafts are rotatably installed at the upper and lower ends of the concave frame seat. A central bevel gear is sleeved and fixed at the head of the horizontal shaft, and a mating bevel gear that meshes with the central bevel gear is installed on the vertical shafts at both the upper and lower ends. A protective cover is also fixedly installed on the crossbar seat.

[0017] By adopting the above technical solution, the arrangement of the crossbar seat, concave frame seat, horizontal shaft, vertical shaft, central bevel gear, and mating bevel gear forms a coaxial reverse transmission mechanism. When the drive component drives the impeller to rotate, it can synchronously drive the vertical shaft at the lower end of the concave frame seat to rotate. The lower vertical shaft drives the horizontal shaft to rotate stably through the meshing of the central bevel gear and the mating bevel gear, thereby driving the vertical shaft at the upper end of the concave frame seat to rotate synchronously in the opposite direction. In this way, the transmission mechanism can drive the top packing frame and the bottom packing frame to rotate synchronously in the opposite direction, thereby increasing the uniformity of the gas-liquid mixing reaction through dynamic operation.

[0018] Optionally, the second spray plate includes a positioning frame, a liquid supply top pipe, and a diversion bottom pipe connected to the liquid supply top pipe. The positioning frame is fixedly installed in the tower body, the liquid supply top pipe is fixedly installed in the positioning frame, and the diversion bottom pipe is evenly installed on the lower end face of the liquid supply top pipe, and the diversion bottom pipe is equipped with several sets of spray heads.

[0019] By adopting the above technical solution, the positioning frame of the second spray plate ensures the installation stability of the liquid supply top pipe and the diversion bottom pipe. The design of the liquid supply top pipe and the diversion bottom pipe allows the spray liquid to be evenly distributed in the tower, and the spray head further disperses the spray liquid, performing secondary spraying on the exhaust gas after it has been treated by the packing assembly, ensuring that the exhaust gas is treated more thoroughly.

[0020] Optionally, the liquid storage tank includes a tank box, a tank cover, and a stirring rod assembly. The tank box is fixedly installed in the tower body, the tank cover is fixedly installed on the upper end face of the tank box, and there are two stirring rod assemblies, with the heads of the two stirring rod assemblies rotatably installed at both ends of the tank cover. A drive motor for driving the two stirring rod assemblies to rotate is also fixedly installed on the outer side of the tank cover.

[0021] By adopting the above technical solution, the stirring rod assembly in the liquid storage tank rotates under the drive of the drive motor, which can stir the spray liquid in the tank, so that the chemical components in the spray liquid are evenly distributed, ensuring that the pH value of the spray liquid is the same everywhere, thereby ensuring a uniform and stable supply of treatment liquid.

[0022] Optionally, the supply assembly includes a liquid supply pump and a distribution pipe. The liquid supply pump is fixedly installed on the tower body. The lower end of the distribution pipe is connected to the outlet of the liquid supply pump, and the upper end of the distribution pipe is connected to the spiral pipe and the liquid supply top pipe respectively. The suction port of the liquid supply pump is equipped with a suction pipe that extends into the tank.

[0023] By adopting the above technical solution, the supply pump of the supply component draws the spray liquid from the storage tank and supplies it to the first and second spray plates respectively through the diversion pipe, realizing the recycling of the spray liquid. The installation of the suction pipe ensures that the supply pump can effectively draw the spray liquid from the tank, ensuring the normal operation of the equipment.

[0024] Optionally, the drive assembly includes a bottom motor and a drive rod. The bottom motor is fixedly installed in the tower body, the impeller is sleeved and fixed on the output shaft of the bottom motor, the drive rod is vertically arranged above the bottom motor, and the drive rod is connected to the output shaft of the bottom motor through a reduction gearbox. The vertical shaft at the lower end of the concave frame is fixed to the head of the drive rod through a coupling.

[0025] By adopting the above technical solution, the bottom motor of the drive component drives the impeller to rotate via a drive rod, providing power for the flow of exhaust gas within the tower. The drive rod is connected to the vertical shaft at the lower end of the concave frame, which drives the packing assembly to rotate, realizing the operation of multiple components from a single power source and improving energy utilization efficiency. A gearbox ensures that the impeller rotates at high speed to drive the exhaust gas upward, and then the gearbox reduces the speed, allowing the packing assembly to rotate at a low speed to avoid droplet splashing, thus achieving differential rotation between the two components.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] This application utilizes the synergistic effect of multi-stage spraying and packing components. During operation, the first spray disc treats the exhaust gas in sections, followed by secondary treatment via the packing components and a second spray disc. The impeller accelerates the exhaust gas flow, significantly increasing the contact area and time between the exhaust gas and the spray liquid, thus enhancing the absorption and removal of pollutants and achieving highly efficient exhaust gas treatment. Simultaneously, a wire mesh demister in the exhaust cap removes liquid droplets from the exhaust gas, improving the quality of exhaust emissions and reducing secondary pollution.

[0028] The drive assembly not only rotates the impeller to accelerate the flow of exhaust gas within the tower, ensuring full contact between the exhaust gas and the spray liquid and improving treatment efficiency, but also simultaneously drives the vertical shaft at the lower end of the concave frame, which in turn rotates the packing assembly. This allows a single power source to drive multiple components, improving energy efficiency. Furthermore, the bottom packing frame can be driven to rotate synchronously in the opposite direction by a set of coaxial reverse-rotating components. This ensures more even distribution of flue gas into the packing during spraying, and also more uniform distribution of the liquid sprayed from the upper second spray plate into the packing, achieving better contact between the exhaust gas and the spray liquid.

[0029] The pH value adjustment and control system can monitor and adjust the pH value of the spray liquid in the storage tank in real time, ensuring that the spray liquid is always at a suitable acidity or alkalinity, thus guaranteeing the treatment effect on waste gases of different properties and improving the adaptability and stability of the equipment.

[0041] The present application will be further described in detail below with reference to the accompanying drawings.

[0042] This application discloses a high-efficiency waste gas treatment spray tower.

[0043] Reference Figure 1 , Figure 2 and Figure 3A high-efficiency waste gas treatment spray tower includes a tower base 1, a tower body 2 fixedly installed on the upper surface of the tower base 1, an air inlet 20 fixedly installed on one side of the tower body 2, and an air outlet cap 3 fixedly installed on the top of the tower body 2. A first spray plate 4, a packing assembly 5, and a second spray plate 6 are arranged sequentially from bottom to top in the tower body 2. The first spray plate 4, the packing assembly 5, and the second spray plate 6 are all fixedly connected to the tower body 2. A liquid storage tank 7 is fixedly installed in the tower base 1, and a supply assembly 8 is also installed on the tower base 1 to supply the liquid in the liquid storage tank 7 to the first spray plate 4 and the second spray plate 6. A fan impeller 10 is also installed at the bottom of the tower base 1, and a drive assembly 9 for driving the fan impeller 10 to rotate is also fixedly installed in the tower base 1. The tower base 1 ensures the stable vertical placement of the tower body 2. The inlet 20 and outlet hood 3 ensure a stable flow of waste gas into the tower body 2. After treatment, the gas is discharged through the outlet hood 3. The first spray plate 4, the packing assembly 5, and the second spray plate 6 are arranged sequentially from bottom to top within the tower body 2, achieving efficient sequential treatment of the waste gas. The first spray plate 4 directly reacts with the waste gas through atomized treatment liquid. The packing assembly 5 and the second spray plate 6 work together to ensure sufficient reaction between the waste gas and the treatment liquid within the packing. The impeller 10 accelerates the flow of waste gas within the tower, ensuring full contact between the waste gas and the spray liquid and improving treatment efficiency. Simultaneously, the liquid storage tank 7 and the supply assembly 8 ensure a continuous supply of spray liquid, guaranteeing continuous waste gas treatment.

[0044] Reference Figure 1 and Figure 2 The exhaust cap 3 includes a converging tower cover 31, a wire mesh demister 32, and an exhaust pipe 33. The converging tower cover 31 is sealed and fixed to the top of the tower body 2. The wire mesh demister 32 is fixedly installed in the converging tower cover 31, and the exhaust pipe 33 is vertically fixed to the head of the converging tower cover 31. The converging tower cover 31 in the exhaust cap 3 can converge the treated exhaust gas, allowing the exhaust gas to be discharged more concentratedly through the exhaust pipe 33. The wire mesh demister 32 can effectively remove liquid droplets carried in the exhaust gas, preventing liquid droplets from being discharged with the exhaust gas, improving the quality of exhaust gas emissions, and reducing secondary pollution to the environment.

[0045] Reference Figure 2 The supply assembly 8 includes a liquid supply pump 81 and a distribution pipe 82. The liquid supply pump 81 is fixedly installed on the tower body 2. The lower end of the distribution pipe 82 is connected to the outlet of the liquid supply pump 81, and the upper end of the distribution pipe 82 is connected to the spiral pipe 42 and the liquid supply top pipe 62 respectively. The suction port of the liquid supply pump 81 is equipped with a suction pipe that extends into the tank 71. The liquid supply pump 81 of the supply assembly 8 draws the spray liquid from the storage tank 7 and supplies it to the first spray plate 4 and the second spray plate 6 respectively through the distribution pipe 82, realizing the recycling of the spray liquid. The installation of the suction pipe ensures that the liquid supply pump 81 can effectively draw the spray liquid in the tank 71, ensuring the normal operation of the equipment.

[0046] Reference Figure 1 and Figure 2 The drive assembly 9 includes a bottom motor 91 and a drive rod 92. The bottom motor 91 is fixedly installed in the tower body 2. The impeller 10 is sleeved and fixed on the output shaft of the bottom motor 91. The drive rod 92 is vertically arranged above the bottom motor 91 and is connected to the output shaft of the bottom motor 91 through a reduction gearbox 93. The vertical shaft 552 at the lower end of the concave frame 55 is fixed to the head of the drive rod 92 through a coupling. By adopting the above technical solution, the bottom motor 91 of the drive assembly 9 drives the impeller 10 to rotate through the drive rod 92, providing power for the flow of exhaust gas in the tower. Meanwhile, the drive rod 92 is connected to the vertical shaft 552 at the lower end of the concave frame 55, which can drive the packing assembly 5 to rotate, realizing that one power source drives multiple components to work, improving energy utilization efficiency. The setting of the reduction gearbox 93 ensures that the impeller 10 rotates at high speed to drive the exhaust gas to flow upward. After being reduced by the reduction gearbox 93, the packing assembly 5 can rotate at low speed to avoid droplet splashing, thereby realizing the differential rotation between the two.

[0047] Reference Figure 6 and Figure 7 The first spray plate 4 includes an annular seat 41, a spiral tube 42, and several sets of partition ring plates 43 with different diameters. The spiral tube 42 is fixedly installed on the upper end face of the annular seat 41, and several atomizing nozzles 421 are evenly installed on the lower end face of the spiral tube 42. The partition ring plates 43 are coaxially arranged and fixedly installed on the lower end of the annular seat 41. The design of the spiral tube 42 and atomizing nozzles 421 of the first spray plate 4 allows the spray liquid to be evenly sprayed in the tower in the form of atomization, increasing the contact area between the spray liquid and the waste gas and improving the absorption effect of pollutants in the waste gas. The partition ring plates 43 can separate and guide the waste gas, making it easier for the atomizing nozzles 421 to spray and react efficiently in different areas, making the waste gas more evenly distributed in the tower and further enhancing the treatment effect.

[0048] Reference Figure 6 and Figure 7 The annular base 41 includes an outer ring frame 411, connecting ear plates 412, and a cross bracket 413 for mounting the spiral tube 42 and the partition ring plate 43. The connecting ear plates 412 are symmetrically fixed on both sides of the outer surface of the outer ring frame 411, and the cross bracket 413 is fixedly installed in the outer ring frame 411. The structure of the outer ring frame 411, connecting ear plates 412, and cross bracket 413 of the annular base 41 provides a stable mounting foundation for the spiral tube 42 and the partition ring plate 43, ensuring the stability of the first spray plate 4. The connecting ear plates 412 facilitate the connection and fixation of the first spray plate 4 to the tower body 2, while the cross bracket 413 rationally allocates the installation space for the spiral tube 42 and the partition ring plate 43, making the structure more compact.

[0049] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 The packing assembly 5 includes an annular outer shell 51, a top packing frame 52, and a bottom packing frame 53. The annular outer shell 51 is fixedly installed in the tower body 2. The top packing frame 52 is positioned above the bottom packing frame 53, and both the top and bottom packing frames 52 and 53 are rotatably installed within the annular outer shell 51. The rotatable installation of the top and bottom packing frames 52 and 53 within the annular outer shell 51 allows the packing to rotate under the influence of the exhaust gas flow, increasing the contact opportunity between the packing and the exhaust gas and improving the adsorption and filtration efficiency of the packing for pollutants in the exhaust gas. Simultaneously, the rotation of the top and bottom packing frames 52 and 53 ensures that the sprayed treatment liquid from the upper end enters the packing more evenly. The annular outer shell 51 also ensures the integrity and stability of the packing assembly 5.

[0050] Reference Figure 3 , Figure 4 and Figure 5 A crossbar seat 54 is installed on the inner side of the annular outer shell 51. One end of the crossbar seat 54 is fixedly connected to the annular outer shell 51, and a concave frame seat 55 is fixedly installed on the other end of the crossbar seat 54. A horizontal shaft 551 is rotatably installed in the middle of the concave frame seat 55, and vertical shafts 552 are rotatably installed at the upper and lower ends of the concave frame seat 55. A central bevel gear 553 is fixedly fitted onto the head of the horizontal shaft 551, and a mating bevel gear 554 that meshes with the central bevel gear 553 is installed on both the upper and lower ends of the vertical shaft 552. A protective cover 56 is also fixedly installed on the crossbar seat 54. The crossbar seat 54, concave frame seat 55, horizontal shaft 551, vertical shaft 552, central bevel gear 553, and mating bevel gear 554 form a coaxial reverse transmission mechanism. The protective cover 56 is used to protect this coaxial reverse transmission mechanism and prevent the sprayed liquid from affecting the gear transmission. When the drive assembly 9 drives the impeller 10 to rotate, it synchronously drives the vertical shaft 552 at the lower end of the concave frame 55 to rotate. The lower vertical shaft 552 drives the horizontal shaft 551 to rotate stably through the meshing of the middle bevel gear 553 and the cooperating bevel gear 554, which in turn drives the vertical shaft 552 at the upper end of the concave frame 55 to rotate synchronously in the opposite direction. In this way, the top packing frame 52 and the bottom packing frame 53 can be driven to rotate synchronously in the opposite direction through this transmission mechanism, thereby increasing the uniformity of the gas-liquid mixing reaction through the dynamic operation process.

[0051] Reference Figure 8 and Figure 9The second spray plate 6 includes a positioning frame 61, a liquid supply top pipe 62, and a diversion bottom pipe 63 connected to the liquid supply top pipe 62. The positioning frame 61 is fixedly installed in the tower body 2, the liquid supply top pipe 62 is fixedly installed in the positioning frame 61, and the diversion bottom pipe 63 is evenly installed on the lower end face of the liquid supply top pipe 62, and several sets of spray heads 631 are installed on the diversion bottom pipe 63. The positioning frame 61 of the second spray plate 6 ensures the installation stability of the liquid supply top pipe 62 and the diversion bottom pipe 63. The design of the liquid supply top pipe 62 and the diversion bottom pipe 63 allows the spray liquid to be evenly distributed in the tower, and the spray heads 631 further disperse the spray liquid, performing secondary spraying on the exhaust gas after treatment by the packing assembly 5, ensuring that the exhaust gas is treated more thoroughly.

[0052] Reference Figure 1 , Figure 2 and Figure 10 The liquid storage tank 7 includes a tank 71, a cover 72, and a stirring rod assembly 73. The tank 71 is fixedly installed in the tower body 2, and the cover 72 is fixedly installed on the upper surface of the tank 71. There are two sets of stirring rod assemblies 73, with the heads of the two sets of stirring rod assemblies 73 rotatably mounted at both ends of the cover 72. A drive motor 74 for driving the two sets of stirring rod assemblies 73 is also fixedly installed on the outer surface of the cover 72. Driven by the drive motor 74, the stirring rod assembly 73 in the liquid storage tank 7 rotates, which can stir the spray liquid in the tank 71, so that the chemical components in the spray liquid are evenly distributed, ensuring that the pH value of the spray liquid is the same throughout, thereby ensuring a uniform and stable supply of treatment liquid.

[0053] A pH adjustment and control system can also be installed on the tower base 1. This system can monitor the pH value of the spray liquid in the storage tank 7 in real time and adjust it as needed, ensuring the treatment effect of the spray liquid on pollutants in the exhaust gas and enabling the equipment to adapt to the treatment needs of exhaust gases with different properties. The pH adjustment and control system includes a pH sensor, a controller, and an additive pump (valve). The pH sensor is responsible for measuring the hydrogen ion concentration in the solution in real time and converting it into an electrical signal. The controller is responsible for receiving the electrical signal from the pH sensor, converting it into a readable pH value, and comparing it with the preset target pH value. The additive pump / valve is responsible for accurately adding pH adjusters (acids or bases) to the solution. In actual use, the pump or valve will add pH adjusters at a set rate or dosage according to the controller's instructions.

[0054] The implementation principle of a high-efficiency waste gas treatment spray tower according to an embodiment of this application is as follows: In actual use, the waste gas to be treated enters the tower body 2 through the air inlet 20. At this time, the drive assembly 9 is started, and its bottom motor 91 starts to run, driving the drive rod 92 to rotate. The drive rod 92 drives the impeller 10 to rotate, and the wind force generated by the impeller 10 causes the waste gas to flow upward in the tower body 2; on the other hand, the drive rod 92 drives the top packing frame 52 and the bottom packing frame 53 of the packing assembly 5 to rotate through the transmission mechanism.

[0055] Simultaneously, the liquid supply pump 81 of the supply component 8 is activated, drawing the spray liquid from the storage tank 7 and delivering it to the first spray plate 4 and the second spray plate 6 respectively through the diversion pipe 82. Atomizing nozzles 421 are distributed on the spiral tube 42 of the first spray plate 4. After being atomized by the atomizing nozzles 421, the spray liquid can be evenly sprayed. The exhaust gas first passes through the spray treatment of the first spray plate 4, achieving the first contact reaction between the exhaust gas and the spray liquid. To better treat the exhaust gas, the first spray plate 4 is equipped with several dividing ring plates 43, which can divide the exhaust gas into sections for treatment, allowing the spray liquid to contact the exhaust gas more precisely.

[0056] The exhaust gas, after the first spray treatment, continues to flow upwards and enters the packing assembly 5. The packing material laid in the top packing frame 52 and the bottom packing frame 53 increases the contact area and contact time between the exhaust gas and the spray liquid, which is beneficial for the adsorption and filtration of pollutants in the exhaust gas. The liquid supply pump 81 supplies liquid to the second spray plate 6 through the diversion pipe 82. The spray head 631 on the bottom diversion pipe 63 of the second spray plate 6 disperses the spray liquid into the packing material, allowing the pollutants in the exhaust gas to be more fully treated by the spray liquid in the packing material. To avoid uneven distribution of the treatment liquid in the packing material affecting the exhaust gas treatment efficiency, the top packing frame 52 and the bottom packing frame 53 rotate in opposite directions under the drive rod 92, ensuring that the treatment liquid in the second spray plate 6 can enter the packing material evenly and react with the exhaust gas.

[0057] After being processed by the packing assembly 5, the exhaust gas rises to the exhaust cap 3. The wire mesh demister 32 inside the exhaust cap 3 can remove the liquid droplets carried in the exhaust gas after being treated by spraying and the packing layer, reducing the moisture in the exhaust gas and the pollutants that may be carried out with the liquid droplets. Finally, the clean exhaust gas is stably discharged through the exhaust pipe 33.

[0058] During equipment operation, the control system installed on the tower base 1 plays a crucial role. A pH sensor monitors the pH value of the spray solution in the storage tank 7 in real time. When the pH value exceeds the preset range, the controller activates the acid or alkali addition device to add the appropriate chemical agent to the storage tank 7, adjusting the pH value of the spray solution to ensure treatment effectiveness.
