Description

Technical Field

[0001] The present invention relates to the field of spraying equipment, in particular to a high-safety organic waste gas treatment device. Background Art

[0002] In the field of industrial production, especially in the chemical industry, a large amount of waste gas is usually generated during the production process. In order to prevent such waste gas from polluting the environment, the waste gas usually needs to be detoxified before being discharged, such as spraying, dust reduction or filtration, etc. The equipment used in the spraying process is mainly a spray tower, which absorbs and neutralizes harmful substances in the waste gas by spraying different types of liquids into the waste gas.

[0003] For related technologies, please refer to the Chinese patent publication number CN114307463B, which discloses a large temperature difference spray tower. The spray tower includes a main body, a flue gas inlet at the bottom of the main body, a flue gas outlet at the top of the main body, and several spray layers arranged from bottom to top. The upper part of the spray tower body is provided with a spray water inlet connected to the topmost spray layer. The spray layers are provided with nozzles for atomizing the liquid. Adjacent spray layers are provided with hollow liquid collectors in the middle. The liquid collectors are connected to the adjacent spray layers below them by spray water transport pipes. A water collection tank is provided at the bottom of the spray tower body, which is connected to the spray water outlet. Different spray layers use different spray temperatures to cool the flue gas in a step-by-step manner, improve the heat exchange and waste heat recovery efficiency, and increase the temperature difference between the spray water inlet and outlet.

[0004] Regarding the above-mentioned related technologies, during the spraying process, different spray liquids are required to remove different harmful gases in the exhaust gas, such as clean water, alkaline solution, acidic solution and paraffin oil, etc. Since insoluble particles or oily or viscous particles are easily present in the exhaust gas, they are easily mixed with the spray liquid and adhere to the inner wall of the spray tower during the spraying process. When the spray tower works for a long time, the spray tower needs to be cleaned regularly to remove the particles or sticky attachments on the inner wall. For large spray towers, workers are also required to enter the spray tower to perform cleaning operations during cleaning, and there are safety hazards in the cleaning process. Summary of the Invention

[0005] In order to facilitate the cleaning of attachments on the inner wall of the spray tower and improve the safety during the cleaning process, the present application provides a high-safety organic waste gas treatment equipment.

[0006] This application provides a highly safe organic waste gas treatment device, which adopts the following technical solutions:

[0007] A high-safety organic waste gas treatment device includes a spray tower. A plurality of partitions are arranged vertically in the spray tower. The plurality of partitions divide the spray tower into a plurality of independent spray layers. The spray tower is provided with a spray component for delivering spray liquid into the spray layer. A plurality of jet parts are provided in all the spray layers. An air delivery pipe is connected between the jet part and the spray layer below. The air delivery pipe cooperates with the jet part to guide the waste gas from bottom to top through the adjacent spray layers in sequence. The jet part allows the waste gas to enter the corresponding spray layer along the tangent direction of the inner surface of the spray layer, and forms a swirling airflow of the waste gas flowing in a spiral direction in the spray layer. An accelerator is provided in the spray layer for accelerating the initial velocity of the waste gas when it is ejected from the jet part. The spray part includes a liquid supply pipe and several spray heads corresponding to the jet part. The spray heads are in the direction of the axis of the spray tower and are arranged tilted from top to bottom. The liquid supply pipe passes through the spray tower and is connected with all the spray heads, and transports spray liquid to the spray heads. The spray heads make the spray liquid enter the spray layer in the form of mist, and at least part of the swirling airflow passes through the diffusion range of the spray liquid. The lower end of the spray layer is connected with a return pipe for recovering the spray liquid, and a guide block is provided at the lower end of the spray layer. The guide block guides the spray liquid to flow to the return pipe. A cleaning plate is provided in the spray layer. The cleaning plate is in contact with the inner surface of the spray layer and the upper surface of the guide block. The spray tower is provided with a driving member for driving the cleaning plate to rotate along the inner surface of the spray layer.

[0008] By adopting the above technical solution, the air supply pipe inputs the exhaust gas into the spray tower. The exhaust gas enters the spray layer under the action of the air supply pipe and the jet part, and forms a swirling airflow under the action of the inner surface of the spray layer. During this process, the accelerator provides acceleration for the exhaust gas. The liquid supply pipe inputs the spray liquid into the spray head, causing the spray liquid to diffuse in a mist form. The swirling airflow passes through the diffused spray and convects with the spray and mixes with each other. The mist spray liquid reacts with the exhaust gas and detoxifies the exhaust gas. Under the action of gravity, the mist spray liquid converges on the guide block and flows along the guide block to the return pipe, which facilitates the recovery of the spray liquid through the return pipe. When the inner wall of the spray layer and the guide block need to be cleaned, the cleaning plate is driven by the driving member to move within the cleaning layer, so that the cleaning plate cleans the inner surface of the cleaning layer and the upper surface of the guide block. The cleaned liquid continues to flow toward the return liquid pipe under the action of gravity. The spray tower does not need to be disassembled during the cleaning process, and the cleaning personnel do not need to enter the interior of the spray tower, which improves the safety of the cleaning process.

[0009] Optionally, the jet part includes a rotating ring and multiple air guide blocks, the rotating ring is coaxially connected to the spray tower, the cleaning plate is located on the inner side of the rotating ring and moves synchronously with the rotating ring, the driving part drives the rotation around its own axis through the cleaning plate, the multiple air guide blocks are evenly arranged along the circumference of the rotating ring, and the air guide blocks are opened with through holes arranged parallel to the tangential direction of the rotating ring, the spray tower is provided with an annular cavity for installing the rotating ring, all the through holes are connected to the corresponding annular cavities, one end of the air pipe is connected to the annular cavity, and the other end is connected to the adjacent spray layer below.

[0010] By adopting this technical solution, the air pipe transports the treated exhaust gas from the lower spray layer into the annular cavity. The exhaust gas then passes through the rotating ring and the air guide block along the through-holes and is ejected into the spray layer. When the driving member rotates the rotating ring, the rotating ring moves the air guide block, making it easier to adjust the position between the air guide block and the spray head, improving the applicability of the spray process.

[0011] Optionally, the accelerator includes a rotating tube and several branch tubes, one end of the liquid supply tube connected to the spray head is coaxially arranged with the axis of the spray tower, the rotating tube is coaxially rotatably connected to the lower end of the liquid supply tube, the liquid supply tube is provided with a liquid discharge port connected to the rotating tube, several branch tubes are evenly arranged along the circumference of the rotating tube, and all branch tubes are connected to the rotating tube, one end of the branch tube away from the rotating tube passes through the air guide block and is connected to an atomizing nozzle, and the spray direction of the atomizing nozzle is the same as the flow direction of the exhaust gas when passing through the through hole.

[0012] By adopting this technical solution, the spray liquid in the liquid supply pipe enters the rotating pipe through the liquid discharge port, flows along the branch pipe to the atomizing nozzle, and finally enters the through-hole of the corresponding air guide block. The flow of the atomized spray liquid drives the air flow in the through-hole, thereby accelerating the flow rate of the exhaust gas and further improving the mixing effect of the spray liquid and the exhaust gas.

[0013] Optionally, the spray head includes several support tubes, several atomizing parts, a movable ring and a connecting rod. The support tubes correspond one-to-one to the jet parts and are hinged to the liquid supply tube along the vertical direction. The air supply tube is fixedly connected to a rotating rod that supports the rotation of the support tube, and a first hose is connected between the support tube and the liquid supply tube. The atomizing part is connected to one end of the support tube away from the rotating tube and is arranged to be inclined vertically so that the spray sprayed by the atomizing part forms convection with the swirling airflow. The movable ring is sleeved on the outside of the liquid supply tube and is slidably connected to the liquid supply tube vertically. The spray tower is provided with a lifting member for driving the movable ring to move axially. The connecting rod corresponds one-to-one to the support tubes. One end of the connecting rod is hinged to the corresponding support tube vertically, and the other end is hinged to the movable ring.

[0014] By adopting this technical solution, the spray liquid in the liquid supply pipe flows through the first hose into the branch pipe, which supports the atomizing unit and delivers the spray liquid to the atomizing unit. When the lifting member drives the movable ring to move vertically, supported by the rotating rod, the movable ring drives the supporting pipe to rotate vertically via the connecting rod, thereby vertically adjusting the height of the atomizing unit and thus the spray range of the atomizing unit.

[0015] Optionally, a second hose is connected between the atomizing part and the support tube, and the atomizing part is fixedly connected to a rotating column parallel to the rotating rod, the support tube is fixedly connected to a support plate, the rotating column passes through the support plate and is rotatably connected to the support plate, and a sprocket group is provided between the rotating column and the rotating rod. When the rotating column rotates around the axis of the rotating rod, the rotating rod causes the rotating column to rotate through the sprocket group, so that the spray direction of the atomizing part is always toward the corresponding rotary airflow.

[0016] By adopting the above technical solution, the spray liquid in the support tube enters the spray part along the second hose. Under the support of the support plate and the rotating column, the spray part and the support tube have vertical movable space. When the support tube rotates vertically, the rotating rod limits the rotating rod through the sprocket group, so that the rotating rod drives the spray part and the support tube to rotate relative to each other, so that during the vertical swing of the support tube, the spray direction of the atomizing part is always toward the corresponding rotary airflow.

[0017] Optionally, the cleaning plate includes an upper plate, a lower plate, a lower side plate and an intermediate plate. The upper plate and the lower plate are symmetrically arranged with any air guide block as the center, and the upper plate and the lower plate are both in contact with the inner surface of the spray layer. The intermediate plate is fixedly connected between the upper plate and the lower plate. The intermediate plate is slidingly connected to the corresponding air guide block along the radial direction of the rotating ring. An elastic member 1 is provided between the intermediate plate and the air guide block. The elastic member 1 applies a thrust away from the axis of the rotating ring to the intermediate plate in a natural state. The lower side plate is located at the lower end portion of the lower plate and is slidingly connected to the lower plate vertically. The lower end face of the lower plate is in conflict with the upper end face of the guide block. A gear ring is coaxially connected in the spray tower. The upper plate is slidingly connected to the gear ring along the radial direction of the rotating ring. The driving member is used to drive the gear ring to rotate.

[0018] By adopting the above technical solution, when the gear ring rotates, the middle plate and the lower plate are driven to rotate through the upper plate, and then the rotating ring is driven to rotate through the connection between the middle plate and the corresponding air guide block. The elastic member pushes the middle plate away from the axis of the spray tower, so that the upper plate and the lower plate fit with the inner surface of the spray layer, which is beneficial to improve the cleaning effect of the upper and lower plates. When the lower plate moves, it drives the lower plate to move. The lower plate fits with the upper end surface of the guide block under the action of its own gravity, and then the guide block is cleaned through the lower plate.

[0019] Optionally, a collecting groove is provided along the circumferential direction on the outer edge of the guide block. The liquid falling on the upper end surface of the guide block flows to the collecting groove under the action of gravity. The return liquid pipe is connected to the collecting groove. A retaining ring is provided in the collecting groove. The retaining ring is provided with a discharge port along the vertical direction. The spray tower is provided with an adjusting part for driving the retaining ring to rotate. The spray tower is provided with a cleaning port connected to the outside world along the horizontal direction. The cleaning port is arranged in parallel on one side of the return liquid pipe along the horizontal direction. When the retaining ring rotates, the discharge port moves between the cleaning port and the return liquid pipe.

[0020] By adopting this technical solution, the guide block guides the spray liquid toward the manifold. Initially, the discharge port faces the return pipe. At this point, the retaining ring blocks the cleaning port, allowing the spray liquid to flow through the discharge port and toward the return pipe. When cleaning the inner wall of the spray layer, the retaining ring is rotated by the adjusting member, so that the discharge port faces the cleaning port. Movement of the cleaning plate pushes debris within the spray layer toward the cleaning port, where it is then discharged. When the debris solidifies, cleaning it prevents it from clogging the return pipe.

[0021] Optionally, a demister is provided in all the spray layers, the demister is located on the inner side of the gear ring and fixed coaxially with the gear ring, the demister is located above the spray head corresponding to the corresponding spray layer, and an avoidance hole is opened in the middle of the demister for the liquid supply pipe to pass through.

[0022] By adopting the above technical solution, the atomizer separates the exhaust gas and the spray liquid, thereby facilitating the recovery of the spray liquid. The atomizer avoids the liquid supply pipe through the avoidance hole. When the gear ring rotates, the atomizer is driven to move, and the condensed spray liquid on the atomizer is removed by centrifugal action.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The air supply pipe inputs the exhaust gas into the spray tower. The exhaust gas enters the spray layer under the action of the air supply pipe and the jet part, and forms a swirling airflow under the action of the inner surface of the spray layer. During this process, the accelerator provides acceleration for the exhaust gas. The liquid supply pipe inputs the spray liquid into the spray head, causing the spray liquid to diffuse in a mist form. The swirling airflow convects with the diffused spray and mixes with the spray. The mist spray liquid reacts with the exhaust gas and detoxifies the exhaust gas. Under the action of gravity, the mist spray liquid converges on the guide block and flows along the guide block to the return pipe, making it easier to recover the spray liquid through the return pipe. When it is necessary to clean the inner wall of the spray layer and the guide block, the driving member drives the cleaning plate to move within the cleaning layer, so that the cleaning plate cleans the inner surface of the cleaning layer and the upper surface of the guide block. The cleaned liquid continues to flow in the direction close to the return pipe under the action of gravity. The spray tower does not need to be disassembled during the cleaning process, and the cleaning personnel do not need to enter the interior of the spray tower, which improves the safety of the cleaning process.

[0025] 2. When the gear ring rotates, the middle plate and the lower plate are driven to rotate through the upper plate, and then the rotating ring is driven to rotate through the connection between the middle plate and the corresponding air guide block. The elastic member pushes the middle plate away from the axis of the spray tower, so that the upper plate and the lower plate fit the inner surface of the spray layer, which is beneficial to improve the cleaning effect of the upper and lower plates. When the lower plate moves, it drives the lower plate to move. The lower plate fits the upper end surface of the guide block under the action of its own gravity, and then cleans the guide block through the lower plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0036] The embodiments of the present application disclose a highly safe organic waste gas treatment device.

[0037] Example:

[0038] Reference Figure 1 and Figure 2 A highly safe organic waste gas treatment device includes a spray tower 1, within which multiple parallel partitions 11 are vertically fixedly connected. These partitions 11 cooperate to divide the spray tower 1 into multiple independent spray levels. A gas chamber 12 is fixedly mounted at the lower end of the spray tower 1. This chamber is connected to an external air pipe, through which waste gas is introduced.

[0039] Reference Figure 1 and Figure 2For all spray layers, air pipes 4 are installed between adjacent spray layers and between the lowest spray layer and the air silo 12. There are multiple air pipes 4, and multiple air pipes 4 are arranged along the circumference of the spray tower 1. A partition 11 is also installed between the air silo 12 and the lowest spray layer. The lower end surface of the partition 11 is a conical surface, and an air guide hole corresponding to the air pipe 4 is opened in the middle of the partition 11. The lower end of the air pipe 4 passes through the partition 11 and is connected to the air guide hole. For the exhaust gas entering the air silo 12, when the exhaust gas spreads to the partition 11, the partition 11 gathers the exhaust gas through the conical surface and guides the exhaust gas through the air guide hole to all corresponding air pipes 4.

[0040] Reference Figure 2 and Figure 4 The spray layer is provided with a jet part 3, which includes a rotating ring 31 and a plurality of air guide blocks 32. The rotating ring 31 is located in the spray tower 1 and rotates coaxially with the spray tower 1. The inner wall of the spray tower 1 is provided with an annular cavity 16 arranged along a ring. The rotating ring 31 is located in the annular cavity 16 and fits the inner wall of the annular cavity 16. The spray tower 1 accommodates the rotating ring 31 through the annular cavity 16 and supports the rotating ring 31 to rotate around its own axis. An annular groove is provided on the outer circle of the rotating ring 31 along the circumference, and the annular groove is connected to the annular cavity 16. The end of the gas pipe 4 away from the partition 11 passes through the spray tower 1 and is connected to the annular groove through the annular cavity 16, thereby transporting the exhaust gas from bottom to top into the annular cavity 16.

[0041] Reference Figure 2 and Figure 4 Multiple air guide blocks 32 are located inside the rotating ring 31 and are evenly distributed along its circumference. Rotation of the rotating ring 31 drives all air guide blocks 32 to move synchronously. Each air guide block 32 has a through hole 321, whose axis is parallel to a tangent to the inner circle of the rotating ring 31. Through hole 321 connects to the annular cavity 16 via an annular groove. Exhaust gas within the annular cavity 16 is guided by the through hole 321 along the tangent to the inner wall of the rotating ring 31 and enters the spray layer. Guided by the inner wall of the spray layer, the exhaust gas forms a swirling airflow.

[0042] Reference Figure 2 and Figure 3 The lower end of the spray tower 1 is also fixed with a liquid supply tank 13 corresponding to each spray layer. The liquid supply tank 13 is used to store the spray liquid required for exhaust gas detoxification. A spray component is installed between the liquid supply tank 13 and the corresponding spray layer. The spray component includes a liquid supply pipe 21 and a spray head 22. One end of the liquid supply pipe 21 is connected to the corresponding liquid supply tank 13, and the other end passes through the spray tower 1 and extends into the corresponding spray layer. The liquid supply tank 13 is equipped with a delivery pump. When the delivery pump is in operation, it drives the spray liquid along the liquid supply pipe 21 to the spray layer.

[0043] Reference Figure 2 and Figure 5The end of the liquid supply pipe 21 away from the liquid supply tank 13 is vertically arranged and coaxial with the spray tower 1. The spray head 22 includes multiple support pipes 221, multiple atomizing parts 222, a movable ring 223 and multiple connecting rods 224. All support pipes 221 are located at the end of the liquid supply pipe 21 away from the liquid supply tank 13, and the support pipe 221 is vertically hinged to the liquid supply pipe 21. The liquid supply pipe 21 is fixedly connected to a rotating rod 227 for supporting the support pipe 221, and the hinge axis of the support pipe 221 is coaxial with the rotating rod 227. A first hose 225 is connected between the support pipe 221 and the liquid supply pipe 21, and the spray liquid in the liquid supply pipe 21 enters the support pipe 221 along the first hose 225.

[0044] Reference Figure 2 and Figure 5 The atomizing section 222 corresponds one-to-one with the support tube 221 and is located at the end of the support tube 221 away from the liquid supply tube 21. A second hose 226 connects the atomizing section 222 and the support tube 221. The spray liquid in the support tube 221 flows along the second hose 226 into the atomizing section 222 and is sprayed out of the atomizing section 222 in a mist-like state, expanding in a conical pattern. The atomizing section 222 is a liquid spray nozzle, which is conventional and will not be described in detail here.

[0045] Reference Figure 2 and Figure 5 The atomizing portion 222 is fixedly connected to a rotating column 228 corresponding to the rotating rod 227. The rotating column 228 is parallel to the rotating rod 227. The support tube 221 is fixedly connected to a support plate 229 corresponding to the rotating column 228. The rotating column 228 passes through the support plate 229 and is rotatably connected to the support plate 229. The atomizing nozzle 233 corresponds one-to-one with the air guide block 32, and the atomizing nozzle 233 is tilted from top to bottom along the axis of the rotating ring 31 pointing to the outer circle. The swirling airflow ejected from the through hole 321 of the air guide block 32 passes through the spray ejected from the atomizing nozzle 233. The spray and the swirling airflow form convection, thereby mixing the spray liquid with the swirling airflow, so that the spray liquid detoxifies the waste gas. The waste gas flow trajectory is spiral, which is conducive to prolonging the reaction time between the waste gas and the spray liquid and improving the detoxification effect of the spray liquid.

[0046] Reference Figure 2 and Figure 5 A sprocket assembly is provided between the rotating rod 227 and the rotating column 228. The sprocket assembly includes a first sprocket 241, a second sprocket 242, and an endless chain 243. The first sprocket 241 is coaxially fixed to the rotating rod 227, and the second sprocket 242 is coaxially fixed to the rotating column 228. The endless chain 243 is wound around the outside of the first sprocket 241 and the second sprocket 242 and meshes with both the first sprocket 241 and the second sprocket 242. The first sprocket 241 is fixed, and the endless chain 243 limits the position of the second sprocket 242.

[0047] Reference Figure 2 and Figure 5 The movable ring 223 is sleeved on the outside of the liquid supply pipe 21 and is located above all support pipes 221. The movable ring 223 is slidably connected to the liquid supply pipe 21 along the axial direction. The connecting rod 224 corresponds to the support pipe 221 one by one, and one end of the connecting rod 224 is vertically hinged to the movable ring 223, and the other end is hinged to the corresponding support pipe 221. When the movable ring 223 moves along the axial direction, the connecting rod 224 drives the support pipe 221 to swing vertically, thereby adjusting the vertical height of the atomizing section 222, adjusting the distance between the atomizing section 222 and the guide block, and changing the spray range of the atomizing section 222, which is suitable for different types of exhaust gas and spray liquid.

[0048] Reference Figure 2 and Figure 5 The spray tower 1 is provided with a lifting member for driving the moving ring 223 to move. The lifting member includes a screw 71, a bevel gear set 72 and an adjusting rod 73. One side of the liquid supply pipe 21 is fixedly connected to a receiving portion. One end of the receiving portion passes through the spray tower 1 horizontally and extends to the outside. The adjusting rod 73 is located in the receiving portion and is rotatably connected to the receiving portion. The screw 71 is arranged vertically, and one end of the screw 71 is rotatably connected to the receiving portion, and the other end is rotatably connected to the liquid supply pipe 21. The bevel gear set 72 is located between the adjusting rod 73 and the screw 71. When the operator rotates the adjusting rod 73, the adjusting rod 73 drives the screw 71 to rotate through the bevel gear set 72.

[0049] Reference Figure 2 and Figure 5 The liquid supply pipe 21 is provided with a vertical groove for accommodating the screw 71, and the movable ring 223 is fixedly connected with a connecting block adapted to the vertical groove. The connecting block is located in the vertical groove and fits with the inner wall of the vertical groove. The screw 71 passes through the connecting block along the axial direction and is threadedly connected to the connecting block. Under the limiting effect of the vertical groove, when the screw 71 rotates, it drives the movable ring 223 to move vertically through the connecting block, and then adjusts the vertical angle of the support tube 221 through the movable ring 223. When the support tube 221 swings, it drives the atomizing part 222 to swing. At this time, the rotating column 228 rotates around the rotating rod 227 driven by the support tube 221. Through the connection effect of the sprocket group, the vertical rotation of the rotating column 228 itself is restricted, and then it rotates relative to the support plate 229. At this time, the spray direction of the spray part is always toward the rotary airflow, thereby improving the convenience of adjustment.

[0050] Reference Figure 4 and Figure 6An accelerator is provided within the spray layer. The accelerator comprises a rotating tube 231 and a plurality of branch tubes 232. The branch tubes 232 correspond one-to-one with the air guide block 32. The rotating tube 231 is located at the lower end of the movable ring 223 and is coaxial with the movable ring 223. The rotating tube 231 is also sleeved on the outside of the liquid supply tube 21 and is coaxially connected to the liquid supply tube 21. A gap is left between the inner wall of the rotating tube 231 and the liquid supply tube 21. The liquid supply tube 21 has a discharge port 211 connected to the rotating tube 231. The spray liquid passes through the discharge port 211 and enters the inner side of the rotating tube 231. The plurality of branch tubes 232 are arranged circumferentially along the rotating tube 231. The branch tubes 232 are connected to the discharge port 211 through the rotating tube 231. After passing through the discharge port 211, the spray liquid enters the branch tubes 232. The end of the branch tube 232 away from the rotating tube 231 passes through the air guide block 32 and enters the through hole 321.

[0051] Reference Figure 4 and Figure 6 One end of branch pipe 232, located within through-hole 321, is fixedly connected to atomizing nozzle 233. Atomizing nozzle 233 is positioned along the axis of through-hole 321. The spray liquid is sprayed from atomizing nozzle 233 in a mist-like state and flows along through-hole 321 into the inner cavity of the spray layer. The spray from atomizing nozzle 233 initially mixes with the exhaust gas in through-hole 321, improving the mixing effect between the exhaust gas and the spray liquid while accelerating the flow of the exhaust gas. This in turn enhances the convection collision effect between the exhaust gas and the spray sprayed from atomizing section 222, further improving the mixing effect between the spray liquid and the exhaust gas.

[0052] Reference Figure 1 and Figure 2 A return pipe 14 connects the spray layer to the liquid supply tank 13. A guide block 15 is fixedly connected to the lower end of the spray layer. The upper end of the guide block 15 is conical, and spray liquid that lands on the upper end of the guide block 15 flows toward the outer edge of the guide block 15 under the action of the conical surface. A manifold 151 is vertically defined on one side of the outer edge of the guide block 15. The return pipe 14 is connected to the manifold 151, and the upper end of the return pipe 14 is no higher than the bottom of the manifold 151. Spray liquid that flows to the outer edge of the guide block 15 converges in the manifold and then flows back into the liquid supply tank 13 through the return pipe 14.

[0053] Reference Figure 2 and Figure 7 The collecting trough 151 is arranged along the circumference of the spray tower 1, and a baffle ring 17 is installed in the collecting trough 151. The baffle ring 17 is coaxially connected to the spray tower 1, and the spray liquid flowing into the collecting trough 151 first flows above the baffle ring 17. The baffle ring 17 has a vertical discharge port 171. In the initial state, the discharge port 171 is located above the return pipe 14, so that the spray liquid above the baffle ring 17 flows through the discharge port 171 to the return pipe 14.

[0054] Reference Figure 2 and Figure 4 , cleaning plates 5 are provided in all spray layers, and there are multiple groups of cleaning plates 5. In this embodiment, two groups of cleaning plates 5 are taken as an example for explanation. The cleaning plates 5 include an upper plate 51, a lower plate 52, a lower side plate 53 and an intermediate plate 54. The upper plate 51 and the lower plate 52 are vertically opposed to each other with any air guide block 32 as the center, and the upper plate 51 is located above the lower plate 52, the intermediate plate 54 is fixedly connected between the upper plate 51 and the lower plate 52, and the intermediate plate 54 is located on the side of the corresponding air guide block 32 close to the axis of the rotating ring 31, and the air guide block 32 is fixedly connected with a sliding rod 323 along the diameter direction of the rotating ring 31, and the sliding rod 323 passes through the intermediate plate 54 and is slidably connected to the intermediate plate 54.

[0055] Reference Figure 2 and Figure 4 An elastic member 322 is installed between the middle plate 54 and the corresponding air guide block 32. This elastic member 322 is a spring with one end fixedly connected to the middle plate 54 and the other end to the air guide block 32. When in its natural state, the elastic member 322 applies a thrust force to the middle plate 54 away from the axis of the rotating ring 31. Guided by the slide rod 323 and pushed by the elastic member 322, the middle plate 54 drives the upper and lower plates 51, 52 to conform to the inner wall of the spray layer.

[0056] Reference Figure 3 and Figure 4 A gear ring 55 is provided in all spray layers. The gear ring 55 is located on the inner surface of the spray tower 1 and is coaxially rotatably connected to the spray tower 1. The spray tower 1 is equipped with a driving member 6 for driving the gear ring 55 to rotate. The driving member 6 includes a motor 61 and a main gear 62. The gear is meshed with the gear ring 55 and is rotatably connected to the spray tower 1. The motor 61 is fixedly connected to the spray tower 1 and is used to drive the main gear 62 to rotate.

[0057] Reference Figure 3 and Figure 4 The upper plate 51 is located directly below the gear ring 55 and is slidably connected to the gear ring 55 along the length of the slide bar 323. Rotation of the gear ring 55 drives the upper plate 51 to rotate about the axis of the gear ring 55. Movement of the upper plate 51 drives movement of the lower plate 52 via the intermediate plate 54, allowing the upper and lower plates 51 and 52 to cooperate in cleaning the inner surface of the spray layer. Movement of the intermediate plate 54 drives rotation of the rotating ring 31 via the slide bar 323, which in turn drives movement of the air guide block 32 via the rotating ring 31. This allows the position of the air guide block 32 to be adjusted laterally, thereby adjusting the trajectory of the swirling airflow.

[0058] Reference Figure 2 and Figure 4The lower plate 53 is located at the lower end of the lower plate 52 and is vertically slidably connected to the lower plate 52. When the lower plate 52 moves along the circumference of the spray layer, it drives the lower plate 53 to move synchronously. The lower end surface of the lower plate 53 is in contact with the upper end surface of the guide block 15. Under the action of its own gravity, the lower plate 53 cleans the lower end surface of the guide block 15 when it moves.

[0059] Reference Figure 2 and Figure 6 The lower end of the liquid supply pipe 21 is coaxially rotated with a mounting tube 9. The end of the lower plate 53 away from the lower plate 52 passes through the mounting tube 9 and extends into the mounting tube 9. The mounting tube 9 is provided with a movable opening for avoiding the lower plate 53. A pressure plate 91 is provided in the mounting tube 9. The pressure plate 91 is located above the lower plate 53 and is in close contact with the lower plate 53. A second elastic member 92 is provided between the pressure plate 91 and the mounting tube 9. The second elastic member 92 is also a spring. One end of the spring is fixedly connected to the pressure plate 91, and the other end is fixedly connected to the mounting tube 9. The second elastic member 92 exerts a downward thrust on the pressure plate 91 in its natural state, thereby pushing the lower plate 53 to fit the guide block 15 through the pressure plate 91, which is conducive to improving the cleaning effect of the lower plate 53.

[0060] Reference Figure 7 and Figure 8 , spray tower 1 (reference Figure 1 ) is also provided with an adjusting member for driving the retaining ring 17 to rotate, and the adjusting member includes a vertical gear 181 and a connecting ring 182. The connecting ring 182 is coaxially fixed to the outer edge of the retaining ring 17, and the connecting ring 182 is fixedly connected to a plurality of tooth blocks along the circumferential direction. The vertical gear 181 is meshed with the tooth blocks and is rotationally connected to the spray tower 1, and a rotating handle 183 is coaxially fixed to the vertical gear 181. The rotating handle 183 passes through the spray tower 1 and extends to the outside of the spray tower 1. The spray tower 1 also has a cleaning port 191 corresponding to the recovery pipe. The cleaning port 191 is arranged horizontally with the return liquid pipe 14. In the initial state, the retaining ring 17 blocks the cleaning port 191, and a detachable waste box 192 is provided in the cleaning port 191.

[0061] Reference Figure 7 and Figure 8 When the attachments on the inner wall of the spray layer solidify into solids, before cleaning the spray layer, the operator rotates the handle 183. Through the meshing action of the vertical gear 181 and the tooth block, the connecting ring 182 drives the retaining ring 17 to rotate, so that the discharge port 171 moves above the cleaning port 191 and connects with the cleaning port 191. The solid waste cleaned by the cleaning plate 5 moves along the retaining ring 17 to the cleaning port 191 under the push of the cleaning plate 5, and falls into the waste box 192 along the cleaning port 191 under the action of gravity. The operator can remove the waste box 192 from the outside to complete the cleaning of the solid attachments. The cleaning process is relatively convenient and does not require the disassembly of the spray tower 1, which is conducive to improving the operator's operating safety.

[0062] Reference Figure 2 and Figure 3 A demister 8 is also provided in the spray layer. The demister 8 is located on the inner side of the gear ring 55 and is coaxially fixed with the gear ring 55. A avoidance hole 81 is vertically opened in the middle position of the demister 8, and the liquid supply pipe 21 passes through the avoidance hole 81. After the exhaust gas is mixed with the spray liquid, it flows toward the partition 11 at the upper end of the corresponding spray layer. After the exhaust gas passes through the demister 8, the demister 8 separates the exhaust gas and the spray liquid. The demister 8 is a prior art and will not be described in detail here. When the gear ring 55 rotates, it drives the demister 8 to rotate, and then accelerates the separation of the spray liquid attached to the demister 8 through centrifugal action.

[0063] The working principle of a high-safety organic waste gas treatment device in the embodiment of the present application is as follows: when the waste gas is input into the spray tower 1, the waste gas circulates in sequence from bottom to top along the gas pipe 4, the rotating ring 31 and the air guide. After the waste gas enters the corresponding spray layer, it moves spirally along the inner wall of the spray layer. At this time, the liquid supply pipe 21 transports the spray liquid in the liquid supply box 13 to the spray layer. At this time, the spray liquid is divided into two parts, one part of which enters the atomizing nozzle 233 along the branch pipe 232 and is sprayed out from the through hole 321 of the air guide block 32. This part of the spray liquid directly mixes with the waste gas in the through hole 321 and accelerates the movement of the waste gas. The other part of the spray liquid is sprayed out from the spray part along the support pipe 221 and forms a spray that coincides with the movement trajectory of the swirling airflow. The swirling airflow and the spray undergo convection and collision, thereby further improving the mixing effect of the spray liquid and the waste gas, and improving the absorption and purification effect of the spray liquid on the waste gas. When the inner wall of the spray tower 1 needs to be cleaned, the gear ring 55 is driven to rotate by the motor 61, so that the gear ring 55 drives the upper plate 51, the lower plate 52 and the lower side plate 53 to move, thereby cleaning the inner wall of the spray tower 1 and the upper end surface of the guide block 15. When the attachment is a liquid spray liquid, the spray liquid is directly pushed through the discharge port 171 and recovered by the return pipe 14. When the attachment is a solid material, the retaining ring 17 is driven to rotate by the adjusting member so that the discharge port 171 of the retaining ring 17 is opposite to the cleaning port 191, and the solid attachment passes through the discharge port 171 and falls into the waste box 192. The operator can clean the solid attachment in the waste box 192 from the outside. The cleaning process does not require the spray tower 1 to be disassembled, and the cleaning personnel do not need to enter the interior of the spray tower 1, thereby improving the safety of the cleaning process.

[0064] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
