Description

Technical Field

[0001] This invention relates to the field of anti-clogging technology for spray towers, specifically to an anti-clogging and efficiency-enhancing high-efficiency spray tower for purifying waste gas. Background Technology

[0002] Spray towers are commonly used purification equipment for industrial waste gas treatment. They rely on the countercurrent contact between waste gas and the packing layer and spray washing liquid inside the tower to achieve the washing and purification of harmful gases. They are widely used in various industrial pollution-generating scenarios.

[0003] Currently, there are two main types of solutions for preventing clogs in spray towers: one is vibration unclogging, as used in patent 201910069038.7, and the other is plug-in type channel unclogging, as used in patents 202020099523.7 and 202510852268.6.

[0004] However, in order to prolong the contact time between the exhaust gas and the spray liquid and improve the purification effect, the industry generally makes the packing layer relatively thick. Over a long period of use, dust, viscous paint residue, and colloids in the exhaust gas will slowly accumulate in the gaps of the packing in an arch-like shape, blocking the gaps from the inside.

[0005] For vibration-based solutions, the vibration force is transmitted upwards from the bottom of the packing layer. The thick packing itself is densely packed, and the weight of the upper packing layers presses it down. When the vibration energy is transmitted upwards, it is buffered and canceled by each layer. In the end, only a small part of the bottom packing can move, while the middle and upper packings are almost still. The vibration effect is greatly reduced, and the more it is shaken, the more compacted it becomes. Not only can it not be disassembled and bridged, but it will also make the packing particles and dirt get stuck even tighter.

[0006] For solutions like inserting rods to clear blockages, they can only open the vents on the support plate, but cannot clear the bridging blockages inside the packing material.

[0007] Moreover, whether it's vibration or insertion, the current method for cleaning the packing is to flush water down from the top of the tower. The dirt and dirty water flushed down flow down the packing layer by layer. Once the upper layer is cleaned, all the dirt falls into the lower layer of packing, which is equivalent to directly transferring the blockage point in the upper layer to the lower layer. It gets blocked again not long after cleaning, which is a complete waste of effort.

[0008] In summary, the existing solutions not only fail to completely eliminate the internal bridging blockage of thick packing, but also cause secondary blockage in the lower layers after cleaning.

[0009] Based on this, the present invention designs a high-efficiency spray tower for purifying exhaust gas with anti-clogging and enhanced efficiency to solve the above problems. Summary of the Invention

[0010] The purpose of this invention is to provide a high-efficiency spray tower for purifying exhaust gas with anti-clogging and enhanced efficiency, so as to solve the problems mentioned in the background art.

[0011] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency spray tower for purifying exhaust gas with anti-clogging and enhanced efficiency, comprising a shell and a plurality of spray heads arranged vertically inside the shell, each spray head having a corresponding thin-plate filter unit and a collection pipe below it; the thin-plate filter unit includes a frame fixedly connected to the inner wall of the shell, a packing frame slidably connected to the inner wall of the frame, the top of the packing frame having a hollow structure; a receiving plate slidably connected to the frame is provided below the packing frame, and a vibration unit for driving the packing frame to vibrate is arranged between the packing frame and the receiving plate; a plurality of vent holes are provided on the receiving plate, and a rod is fixedly installed at the bottom of the packing frame corresponding to the position of the vent holes, with a gap between the rod and the vent holes; a plurality of through holes are also provided at the bottom of the packing frame; a driving unit is provided below the receiving plate, the driving unit being used to drive the receiving plate to rise until the rod blocks the vent holes; the collection pipe is fixed to the inner wall of the shell, a flow port is provided on the receiving plate, and an opening is provided on the collection pipe at the position opposite to the flow port.

[0014] As a further embodiment of the present invention, a plurality of guide ribs are fixedly provided on the receiving plate.

[0015] As a further embodiment of the present invention, the bottom end of the collecting tube penetrates through the housing and extends to the outside of the housing; a baffle is provided at the opening on the collecting tube opposite to the flow port, the baffle is rotatably connected to the side wall of the collecting tube, and the bottom end of the baffle is inclined downward; when the receiving plate slides upward, its top end can push the bottom end of the baffle and open the baffle.

[0016] As a further embodiment of the present invention, the vibration unit includes a cam disposed below the packing frame, and the cam is fixedly connected to a motor; the motor is fixedly mounted on the housing, and the output shaft of the motor passes through the housing and is fixedly connected to the cam.

[0017] As a further embodiment of the present invention, the driving unit includes a driving ring slidably assembled inside the frame, a push rod fixedly provided at the top end of the driving ring, and the end of the push rod being an inclined surface; the side wall of the receiving plate is integrally formed with a contact end, the contact end penetrating the frame and slidingly engaging with the frame, and the contact end being correspondingly located on one side of the push rod.

[0018] As a further embodiment of the present invention, the drive ring is provided with teeth, which mesh with a gear; the shaft of the gear is rotatably mounted on the housing, and the shaft extends through the housing to the outside of the housing to form a knob.

[0019] As a further embodiment of the present invention, when the packing is filled inside the packing frame, the overall volume of the packing is smaller than the internal accommodating space of the packing frame, and an movable gap is reserved between the packing and the inner top wall of the packing frame for the packing to vibrate and move.

[0020] Compared with the prior art, the beneficial effects of the present invention are: This invention, by using a multi-layer series of thin packing frames instead of the traditional thick packing layer, can effectively eliminate the problems of energy attenuation caused by vibration of thick packing and the inability to break up bridging in the middle.

Furthermore, the impurities shaken off directly enter the corresponding collection pipe through the flow port of the receiving plate and are discharged laterally, without falling vertically to the lower filter unit, thus solving the problem of secondary blockage from the root.

[0023] Please see Figures 1-10 The present invention provides a technical solution: a high-efficiency spray tower for purifying exhaust gas with anti-clogging and enhanced efficiency, comprising a shell 1 and a plurality of spray heads 2 arranged vertically inside the shell 1. An air inlet 101 and an air outlet 102 are respectively provided near the bottom and top of the shell 1. A water tank 103 is provided on the bottom wall of the shell 1. The water tank 103 is connected to a circulating water pump 104 outside the shell 1. The circulating water pump 104 and the plurality of spray heads 2 are connected through a delivery pipe 105 to transport the spray liquid. The chemical solution is added through a dosing tank 106 connected to the circulating water pump 104. Each spray head 2 is equipped with a thin plate filter unit and a collection pipe 9 below it. The thin plate filter unit includes a frame 3 fixedly connected to the inner wall of the housing 1. A packing frame 4 is slidably connected to the inner wall of the frame 3. The top of the packing frame 4 has a hollow structure. A receiving plate 5 is slidably connected to the frame 3 below the packing frame 4. A vibration unit for driving the packing frame 4 to vibrate is arranged between the packing frame 4 and the receiving plate 5. Several vent holes 6 are opened on the receiving plate 5. A rod 7 is fixedly installed at the bottom of the packing frame 4 at the position corresponding to the vent holes 6. A gap is left between the rod 7 and the vent holes 6. Several through holes 8 are also opened at the bottom of the packing frame 4. A driving unit is provided below the receiving plate 5. The driving unit is used to drive the receiving plate 5 to rise until the rod 7 blocks the vent holes 6. The collection pipe 9 is fixed to the inner wall of the housing 1. A flow port 10 is opened on the receiving plate 5. An opening 11 is opened on the collection pipe 9 at the position opposite to the flow port 10.

[0024] like Figures 1-5 as well as Figure 9 and Figure 10 As shown: Waste gas circulation path: The waste gas to be treated is continuously introduced through the air inlet 101 at the bottom of the shell 1. The airflow passes through the vent holes 6 of each layer of the receiving plate 5 and the through holes 8 at the bottom of the packing frame 4 from bottom to top, and enters the packing area inside the packing frame 4. After the gas-liquid contact is completed, the clean waste gas gathers upward and is finally discharged outward from the air outlet 102 at the top of the shell 1.

[0025] Circulating spray liquid spraying operation: The water tank 103 on the bottom wall of the shell 1 stores washing water, and the external circulating water pump 104 continuously draws water from the water tank 103; the dosing tank 106 is connected to the circulating water pump 104 and can continuously add neutralizing and dust removal agents to the circulating water circuit; the mixed solution is transported through the delivery pipe 105 to all the vertically arranged spray heads 2 inside the shell 1, and the spray heads 2 spray the washing solution downwards evenly. The solution falls through the hollow structure at the top of the packing frame 4 and comes into countercurrent contact with the upward-flowing exhaust gas, adsorbing dust, colloids and harmful pollutants in the exhaust gas, thus completing the purification; the wastewater after washing finally falls back to the bottom water tank 103, realizing water recycling and reuse.

[0026] Exhaust gas purification status: Each layer of spray head 2 is equipped with an independent thin-plate filter unit and a collection pipe 9 below it; the frame 3 is fixed to the inner wall of the shell 1, providing a sliding mounting carrier for the packing frame 4 and the receiving plate 5; both the packing frame 4 and the receiving plate 5 can slide vertically along the frame 3; under normal conditions, the drive unit is not activated, the receiving plate 5 is in a low position, and the insertion rod 7 maintains a gap with the vent hole 6 on the receiving plate 5 (e.g., Figure 4 As shown), the vent 6 is fully open, and the airflow enters the through hole 8 after passing through the vent 6 and then enters the interior of the packing frame 4. After contacting the packing, it moves upward from the top of the packing frame 4. The hollow structure at the top of the packing frame 4 not only limits the internal packing but also allows the spray liquid to enter the interior of the packing evenly.

[0027] Anti-clogging and cleaning work: When dust and paint residue accumulate in the filler gaps, forming a bridging blockage, the exhaust gas flow at the air inlet 101 is closed. The lower drive unit is then activated, raising the receiving plate 5 upwards. This causes the insert rods 7 fixed at the bottom of the filler frame 4 to be simultaneously inserted into the vent holes 6, completely sealing all vent holes 6 (e.g., ...). Figure 9 and Figure 10 As shown), the receiving plate 5 becomes a collection box with a closed bottom; Subsequently, the vibration unit is activated, causing the packing frame 4 to vibrate up and down at high frequency along the frame 3, breaking up the bridging clumps inside the packing. The detached impurities fall through the bottom through hole 8 of the packing frame 4 and onto the surface of the receiving plate 5, instead of falling onto the lower packing frame 4, thus avoiding secondary pollution and blockage after cleaning. After the receiving plate 5 is raised, the flow port 10 on the plate surface is aligned with the side wall opening 11 of the collection pipe 9. The fallen waste directly flows into the collection pipe 9 and is discharged outward through the flow port 10 and the opening 11. The waste will not fall vertically to the lower filter unit, thus avoiding the problem of upper layer dirt transferring to the lower layer and repeated blockage from the source.

[0028] This invention, by using a multi-layer series of thin packing frames 4 to replace the traditional thick packing layer, can effectively eliminate the problems of energy attenuation caused by vibration of thick packing and the inability to break the bridging in the middle. It ensures that the vibration can completely cover the entire packing layer, causing the packing to rub and collide with each other, breaking the arch-shaped blockage in the packing gaps. Furthermore, the impurities shaken off enter the corresponding collection pipe 9 through the flow port 10 of the receiving plate 5 and are discharged laterally, without falling vertically to the lower filter unit, thus solving the problem of secondary blockage from the root.

[0029] After the blockage is cleared, the drive unit drives the receiving plate 5 to fall back to its original position, the insertion rod 7 disengages from the vent hole 6, the vent hole 6 resumes its conductivity, and the equipment returns to normal exhaust gas purification operation.

[0030] The receiving plate 5 is arc-shaped. The top surface of the receiving plate 5 gradually decreases in height from the center to the outside, while the bottom surface gradually increases in height from the outside to the center. The inner bottom wall of the filling frame 4 gradually decreases in height from the center to the outside, while the ground gradually increases in height from the outside to the center.

[0031] The diameters of both the through hole 8 and the vent hole 6 gradually increase from the center outwards. The outer diameter of the insertion rod 7 is matched with the vent hole 6, and the vent hole 6 and the through hole 8 are distributed alternately.

[0032] like Figure 4 , Figure 6 , Figure 7 and Figure 9 As shown: The receiving plate 5 is shaped like an umbrella with double-sided arcs. The height of the top surface gradually decreases from the center to the outside, forming a downward sloping slag guide surface. The shaken-down impurities automatically slide towards the flow port 10 near the outside due to gravity, avoiding slag accumulation in the center. The bottom surface gradually increases in height from the outside to the center. The exhaust gas flowing from bottom to top is smoothly diffused to all sides after contacting the curved surface, avoiding the formation of large eddies and wind resistance losses caused by the direct airflow and improving the exhaust gas throughput.

[0033] The inner bottom wall of the packing frame 4 is also arc-shaped with a high center and a low outer side. After the spray liquid enters the packing frame 4, it can be guided to disperse evenly in all directions, eliminating dry areas at the edges of the packing and reducing local water shortage and scaling. In addition, it corresponds to the curvature of the top surface of the receiving plate 5, forming a gradually changing gap that is wide in the middle and narrow around the edges. This not only provides sufficient space for the packing to vibrate, but also guides impurities to converge towards the side flow port 10, thereby avoiding the accumulation of impurities inside the packing frame 4 and improving the efficiency of impurities flowing to the flow port 10 and the opening 11.

[0034] Furthermore, during the process of purifying exhaust gas, after the airflow passes through the vent hole 6, it comes into contact with the bottom of the insert rod 7 and is deflected. Then, it hits the bottom wall of the packing frame 4 and enters the through hole 8, where it is diverted and deflected again. The vent hole 6 and the through hole 8 are staggered, which causes the exhaust gas to change direction multiple times, prolonging the gas-liquid contact time and improving the purification effect.

[0035] The curved plate surface improves the flow of impurities, but the flow velocity is fast in the center and slow in the outer ring. The gradual setting of the vent holes 6 and through holes 8, with small holes in the center and large holes in the outer ring, can balance the gas and liquid flow on the plate surface, avoid local flow velocity imbalance, and ensure sufficient gas and liquid contact in each layer of packing, thereby improving the purification effect.

[0036] Several guide ribs 12 are fixedly provided on the receiving plate 5.

[0037] like Figure 7 As shown: When the receiving plate 5 has a smooth arc-shaped surface, the spray liquid easily forms a continuous large-area liquid film on the plate surface. The water flow retention time is long, and it is very easy for salt and chemicals to precipitate out, forming a continuous hard scale that blocks the channels. However, by setting radial guide ribs 12, the overall liquid film can be divided into multiple narrow water flow bands, which can accelerate the surface water flow velocity, shorten the water retention time, and inhibit the crystallization and scaling on the plate surface. At the same time, the guide ribs 12 are arranged radially along the arc-shaped slope, which can divide the movement path for water flow and impurities, preventing impurities from accelerating the accumulation of dirt and waste residue at the outer slag discharge position, avoiding impurity residue, improving the water guiding and slag discharge effect, and playing a long-term anti-clogging role.

[0038] The bottom end of the collection tube 9 passes through the housing 1 and extends to the outside of the housing; a baffle 13 is provided at the opening 11 on the collection tube 9 opposite to the flow port 10. The baffle 13 is rotatably connected to the side wall of the collection tube 9, and the bottom end of the baffle 13 is inclined downward; when the receiving plate 5 slides upward, its top end can push the bottom end of the baffle 13 and open the baffle 13.

[0039] like Figure 4 and Figure 10 As shown: During purification operations, the baffle 13 closes downwards by its own weight (e.g. Figure 4 (As shown in the diagram), close the opening 11 to prevent exhaust gas from leaking out of the collection pipe 9 and to prevent backflow of outside air from disrupting the negative pressure inside the tower; during unblocking, the receiving plate 5 moves upward, the top of the plate contacts the bottom of the baffle 13 and pushes open the baffle 13, opening the slag discharge channel between the flow port 10 and the collection pipe 9 (as shown in the diagram). Figure 10 (As shown in the diagram); once the blockage clearing is complete, the receiving plate 5 descends, and the baffle 13 automatically closes due to its own weight.

[0040] The vibration unit includes a cam 14 located below the packing frame 4, and a motor 15 is fixedly connected to the cam 14. The motor 15 is fixedly mounted on the housing 1, and the output shaft of the motor 15 passes through the housing 1 and is fixedly connected to the cam 14.

[0041] like Figure 6 and Figure 7 As shown: During operation, motor 15 drives cam 14 to rotate, and cam 14 continuously pushes the packing frame 4, causing the packing frame 4 to generate high-frequency up-and-down reciprocating vibration. Furthermore, the use of a thin packing frame 4 prevents the vibration energy from being buffered and attenuated by the weight of the thick packing, allowing it to fully act on the packing within the frame. This eliminates the problems of packing bridging and self-locking due to vertical compression, effectively dispersing any agglomerates within the packing. Figure 6 In the middle, a spring 401 is fixed between the packing frame 4 and the inner wall of the frame 3 to realize the elastic sliding connection of the packing frame 4 and facilitate the reset of the packing frame 4.

[0042] As a further embodiment of the present invention, the driving unit includes a driving ring 16 slidably assembled inside the frame 3, a push rod 17 fixedly provided at the top end of the driving ring 16, and the end of the push rod 17 is a bevel; the side wall of the receiving plate 5 is integrally formed with a contact end 18, the contact end 18 penetrates the frame 3 and slides with the frame 3, and the contact end 18 is correspondingly provided on one side of the push rod 17.

[0043] As a further embodiment of the present invention, the drive ring 16 is provided with teeth, which mesh with a gear 19; the shaft of the gear 19 is rotatably mounted on the housing 1, and the shaft extends through the housing 1 to the outside of the housing to form a knob.

[0044] like Figure 7 and Figure 8 As shown: Before clearing the blockage, the operator can manually rotate the knob outside the housing 1 to drive the gear 19 to mesh with the drive ring 16 and move it horizontally. When the drive ring 16 moves horizontally, the inclined push rod 17 presses the contact end 18, converting the horizontal thrust into a vertical upward lifting force. The contact end 18 slides inside the groove (marked as A1 in the figure) opened on the frame 3, smoothly driving the receiving plate 5 to rise as a whole. After the blockage clearing work is completed, it can be reset. The frame 3 is composed of a collar 301 and a base plate 302 that is bolted to the bottom. After the two are installed, the drive ring 16 is confined inside, which facilitates the installation of the drive ring 16.

[0045] When the packing is filled inside the packing frame 4, the overall volume of the packing is smaller than the internal space of the packing frame 4, and a clearance is reserved between the packing and the inner top wall of the packing frame 4 for the packing to vibrate and move.

[0046] With a thinner packing frame 4, the packing volume can be smaller than the overall internal space of the packing frame 4. When the packing does not fill the packing frame, the packing has more room to move and collide during vibration. The mutual friction and impact between the packings can improve the tearing effect on the arch bridge blockage formed in the gap.
