Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste gas treatment, in particular to a waste gas spraying device for environmental protection waste gas treatment. BACKGROUND

[0002] In the process of industrial production, the emission of a large amount of waste gas has caused serious pollution to the environment, and various harmful substances contained therein not only destroy the ecological balance, but also pose a threat to human health. Therefore, efficient and reliable waste gas treatment technology has become a key link for the sustainable development of industry and environmental protection. The waste gas spraying device, as a common waste gas treatment equipment, has been widely used in many industries such as chemical industry, coating, and electronics due to its simple structure, easy operation, and high purification efficiency.

[0003] Chinese patent CN119588149A discloses a multi-stage spraying treatment device for waste gas of a printing and setting machine, which comprises a spraying tower, three delivery pipes fixedly connected to the outer wall of the spraying tower, a shunt pipe fixedly connected to one end of each of the three delivery pipes, an atomizing nozzle fixedly connected to the inside of the shunt pipe, an air inlet pipe fixedly connected to the bottom of the spraying tower, cooling fins fixedly connected to the inner wall of the spraying tower, and a filter assembly provided on the inner wall of the spraying tower for filtering impurities in the waste gas. The spraying treatment device solves the problem of insufficient gas-liquid contact time, uneven distribution of waste gas, and difficulty in full combination and cooling, resulting in poor treatment effect. The device achieves uniform distribution of waste gas and full contact of atomized water, and pollutants are more efficiently adsorbed, dissolved, or chemically reacted, thereby improving the removal effect.

[0004] The prior art scheme can filter the waste gas in the spray tower through the activated carbon filter plate, but the activated carbon filter plate gradually reaches a saturated state in the long-term use process with the continuous adsorption of pollutants in the waste gas, and then loses the filtering effect. The traditional method for judging the replacement time of activated carbon is mainly to replace it regularly according to the pre-set use period. However, this method has obvious defects. Because the composition, concentration and flow of waste gas generated in the production process of different enterprises differ greatly, and environmental temperature, humidity and other factors also affect the adsorption performance of activated carbon, the actual service life of activated carbon fluctuates greatly. Therefore, replacing activated carbon according to a fixed period cannot accurately judge the real use of activated carbon. In order to ensure that the waste gas treatment effect always meets the environmental protection requirements, the enterprise often has to replace the activated carbon in advance, which undoubtedly causes waste of activated carbon and increases the use cost of waste gas treatment. At the same time, each time the activated carbon is replaced, the operation of the spray tower needs to be stopped, the activated carbon filter plate needs to be removed from the equipment, and after the new activated carbon is replaced, the equipment needs to be reinstalled and debugged. This process is not only complicated and time-consuming, but also the frequent start and stop of the equipment will adversely affect the stability and service life of the equipment, reduce the overall work efficiency and bring many inconveniences to the normal production of the enterprise.

DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application will be described in further detail below in combination with the drawings and specific embodiments.

[0031] Referring to Figures 1 to 11 As shown in the drawings, an exhaust gas spraying device for environmental protection exhaust gas treatment includes a continuous filtering device installed inside a spraying tower 1, the continuous filtering device includes a rotating switching plate 3 installed on the spraying tower 1, the rotating switching plate 3 is internally provided with a plurality of installation spaces, each installation space is internally provided with a storage frame 4, the storage frame 4 is detachably connected with the rotating switching plate 3, the storage frame 4 is used for storing activated carbon 7, a material replacing device 5 is installed on the side of the rotating switching plate 3, the material replacing device 5 is used for automatically replacing the activated carbon 7, a regional flow blocking device 2 is installed below the rotating switching plate 3, and a quantitative sampling device 6 is also installed on the side of the rotating switching plate 3, the quantitative sampling device 6 is used for quantitatively extracting the activated carbon 7 in the storage frame 4.

[0032] After the spraying tower 1 is started, the exhaust gas to be treated enters the tower, and at the same time, the atomizing spraying system is opened to perform atomizing spraying treatment on the exhaust gas. In the rising process of the exhaust gas and the atomizing spraying liquid, the exhaust gas will pass through the rotating switching plate 3 installed on the spraying tower 1. The rotating switching plate 3 is internally provided with a plurality of installation spaces, each installation space is internally provided with a storage frame 4, and the storage frame 4 stores activated carbon 7. When the exhaust gas passes through the rotating switching plate 3, the pollutants in the exhaust gas will be adsorbed and filtered by the activated carbon 7, so as to achieve the purpose of purifying the exhaust gas.

[0033] With the long-time filtering use of the activated carbon 7, the adsorption effect will gradually decrease. In order to accurately judge the adsorption state of the activated carbon 7, the staff can quantitatively extract the activated carbon 7 sample in the storage frame 4 by means of the quantitative sampling device 6 installed on the side of the rotating switching plate 3. By detecting and analyzing the extracted activated carbon 7 sample, according to the key indicators such as adsorption capacity and pollutant residue, it can be accurately judged whether the activated carbon 7 reaches the saturation state and whether it needs to be replaced. Compared with the traditional fixed-period replacement method, this detection method can more accurately reflect the real use of the activated carbon 7, effectively avoid the waste of the activated carbon 7 caused by early replacement, and reduce the exhaust gas treatment cost.

[0034] If the detection result shows that the activated carbon 7 needs to be replaced, the automatic replacement process is started. First, the regional flow blocking device 2 installed below the rotating switching plate 3 is started to shield the area where the activated carbon 7 to be replaced, so as to prevent the exhaust gas from rising from the area, ensure that the exhaust gas will not leak during the replacement process, and avoid interference with the replacement operation. Then, the material replacing device 5 installed on the side of the rotating switching plate 3 starts to work, extracts the storage frame 4 of the activated carbon 7 to be replaced from the rotating switching plate 3, and moves to the inside of the material replacing device 5. In the material replacing device 5, the failed activated carbon 7 is discharged, and at the same time, the new activated carbon 7 is automatically filled into the storage frame 4. After the filling is completed, the material replacing device 5 pushes the storage frame 4 with the replaced activated carbon 7 back to the rotating switching plate 3.

[0035] Then, the rotating switching plate 3 rotates, driving the un-replaced storage frame 4 to switch positions, so that the next storage frame 4 to be replaced is in the corresponding position of the replacement device 5. The replacement device 5 repeats the above replacement steps to replace all activated carbons 7 inside the rotating switching plate 3 in turn.

[0036] When all activated carbons 7 inside the rotating switching plate 3 are replaced, the regional flow blocking device 2 is opened, restoring the normal upward channel of the exhaust gas from all regions, and restoring the normal filtering operation state. The entire activated carbon 7 replacement process does not need to stop the operation of the spray tower 1, realizes automatic replacement without shutdown, effectively improves the work efficiency, reduces the adverse effects on the stability and service life of the equipment caused by frequent start and stop of the equipment, and protects the normal production of the enterprise.

[0037] Referring to Figures 1 to 6 As shown, the rotating switching plate 3 is rotationally connected with the spray tower 1, the top surface and the bottom surface of the rotating switching plate 3 are provided with a plurality of air holes 31, the inside of the rotating switching plate 3 is provided with a plurality of interval support bars 32, the plurality of interval support bars 32 separate the inside of the rotating switching plate 3 into a plurality of installation spaces, and the rotating switching plate 3 further includes a rotating driving device 33 installed outside the spray tower 1, and the output end of the rotating driving device 33 is in transmission connection with the rotating switching plate 3.

[0038] The top surface and the bottom surface of the rotating switching plate 3 are uniformly distributed with a plurality of air holes 31. The air holes 31 constitute the upward channel of the exhaust gas. When the spray tower 1 starts, the exhaust gas to be treated enters the tower and is treated by the atomizing spray system, and then the exhaust gas and the atomizing spray liquid rise together and enter the internal space through the air holes 31 on the bottom surface of the rotating switching plate 3. The inside of the rotating switching plate 3 is provided with a plurality of interval support bars 32, which are arranged at equal intervals to separate the inside of the rotating switching plate 3 into a plurality of independent installation spaces. Each installation space is installed with a storage frame 4, and the storage frame 4 is filled with activated carbon 7. When the exhaust gas passes through the internal space of the rotating switching plate 3, the pollutants in it are adsorbed and filtered by the activated carbon 7, and then the filtered exhaust gas continues to rise through the air holes 31 on the top surface of the rotating switching plate 3. When the quantitative sampling device 6 detects that the activated carbon 7 in the storage frame 4 needs to be replaced because it reaches the saturation state, the regional flow blocking device 2 first blocks the region corresponding to the activated carbon 7 to be replaced, preventing the exhaust gas from rising from the region. Then, the replacement device 5 extracts the storage frame 4 to be replaced from the rotating switching plate 3 and performs activated carbon 7 replacement operation.

[0039] After the replacement of the activated carbon 7 in one of the storage frames 4 is completed, the rotary drive device 33 is started to rotate the rotary switching plate 3. Since the rotary switching plate 3 is divided into multiple installation spaces by the spacing support strips 32, and each installation space is provided with a storage frame 4, the rotation of the rotary switching plate 3 will synchronously rotate all the storage frames 4, so that the next storage frame 4 to be replaced is moved to the corresponding position of the replacement device 5. The replacement device 5 repeats the above-mentioned activated carbon 7 replacement steps to process each storage frame 4 in the rotary switching plate 3 in turn. When the activated carbon 7 in all the storage frames 4 is replaced, the area flow blocking device 2 is opened to restore the normal upward channel of the exhaust gas from all the air vents 31, and the rotary switching plate 3 returns to the initial working state to continue filtering the exhaust gas. The rotary switching plate 3 can realize the position switching of the storage frames 4 without affecting the normal operation of the spray tower 1, and provides a structural basis for automatic replacement of the activated carbon 7 without stopping the machine, effectively improving the working efficiency and stability of the exhaust gas treatment device.

[0040] The rotary drive device 33 is a prior art, which is not described here.

[0041] Referring to Figures 4 to 7 As shown in the figure, the top of the storage frame 4 is provided with a first feeding port 41, the bottom of the storage frame 4 is provided with a first discharging port 42, and the outer side of the storage frame 4 is provided with a penetrating connection hole 43. The penetrating connection hole 43 is further provided with a blocking piece 44 inside, and the blocking piece 44 is further provided with multiple rubber blocking strips 45 inside.

[0042] When the activated carbon 7 needs to be sampled to detect its adsorption state, the sampling end of the quantitative sampling device 6 moves to the inside of the storage frame 4 and penetrates through the penetrating connection hole 43. In this process, the rubber blocking strips 45 of the blocking piece 44 are elastically deformed due to the extrusion of the sampling end, and an avoidance action is generated, so that the sampling end can smoothly enter the inside of the storage frame 4, contact the activated carbon 7 and complete the quantitative sampling operation.

[0043] When the sampling end of the quantitative sampling device 6 completes sampling and exits the storage frame 4, the rubber blocking strips 45 are automatically elastically reset under the action of their own elastic properties. The reset rubber blocking strips 45 are tightly attached to form an effective blocking structure to prevent the activated carbon 7 in the storage frame 4 from entering the penetrating connection hole 43, so as to avoid leakage of the activated carbon 7 or affect the subsequent sampling operation.

[0044] When the activated carbon 7 needs to be replaced, the reloading device 5 cooperates with the storage frame 4 to perform the discharging operation. The movable end of the reloading device 5 is butted against the insertion connection hole 43 of the storage frame 4, the storage frame 4 is moved to the inside by the reloading device 5, and the first discharging port 42 is used as the discharge port of the activated carbon 7. The invalid activated carbon 7 in the storage frame 4 is discharged through the first discharging port 42 into the collection container of the reloading device 5, and the discharging step is completed. After the discharging is completed, the feeding operation is performed. The reloading device 5 feeds the new activated carbon 7 into the inside of the storage frame 4 through the first feeding port 41. The activated carbon 7 is quickly loaded and unloaded, and the replacement efficiency is effectively improved.

[0045] Referring to Figures 1 to 10 As shown, the reloading device 5 includes a guide slide rail 51 fixedly installed outside the spray tower 1, the top of the guide slide rail 51 is provided with a second feeding port, the bottom of the guide slide rail 51 is provided with a second discharging port 511, the second discharging port 511 is installed with a discharging switch 512, the upper side of the second feeding port is installed with a feeding box 53, the discharging end of the feeding box 53 is connected with the second feeding port, the discharging end of the feeding box 53 is installed with a feeding switch 531, the side of the reloading device 5 is installed with a vibration motor 52, and the inside of the reloading device 5 is further installed with a pulling device 54, which is used to pull and move the storage frame 4.

[0046] When the activated carbon 7 needs to be replaced, the pulling device 54 is started, the movable end of the pulling device 54 moves to the insertion connection hole 43 of the storage frame 4 and is butted against the insertion connection hole 43. After the butting is completed, the pulling device 54 moves in the preset direction, drives the storage frame 4 to move along the guide slide rail 51 to the designated position inside the reloading device 5 through the movable end. The accurate guiding effect of the guide slide rail 51 ensures the stability and accuracy of the storage frame 4 during the movement, avoids the deviation or jamming phenomenon, and provides a reliable guarantee for the subsequent discharging and feeding operations.

[0047] After the storage frame 4 is pulled to the designated position inside the reloading device 5, the second discharging port 511 is accurately butted against the first discharging port 42 of the storage frame 4. At this time, the discharging switch 512 is opened, and the vibration motor 52 is started to generate vibration with a certain frequency and amplitude. The vibration makes the invalid activated carbon 7 in the storage frame 4 loose, which is more easily discharged from the first discharging port 42 and the second discharging port 511. Under the action of gravity and the vibration assistance, the invalid activated carbon 7 falls into the collection container inside the reloading device 5 through the second discharging port 511, and the discharging step is completed.

[0048] After the discharging is completed, the feeding tank 53 starts to work. The feeding switch 531 is opened, and the new activated carbon 7 stored in the feeding tank 53 flows into the first feeding port 41 of the storage frame 4 through the discharging end and the second feeding port. At the same time, the vibration motor 52 continuously works, and the vibration generated thereby makes the new activated carbon 7 more uniform and full in the process of flowing into the storage frame 4, so as to avoid problems such as uneven accumulation or voids.

[0049] After the feeding operation is completed, the pulling device 54 is started again, and drives the storage frame 4 with the replaced activated carbon 7 to move reversely along the guide slide rail 51, so as to push the storage frame 4 back into the corresponding mounting space of the rotary switching plate 3, and make the storage frame 4 return to the initial working position. At this time, the replacement device 5 completes a complete activated carbon 7 replacement process, and waits for the next storage frame 4 to be replaced.

[0050] The replacement device 5 can realize automatic pulling movement of the storage frame 4 and efficient discharging and accurate feeding of the activated carbon 7. The whole process does not need manual intervention, and is synchronized with the normal operation of the spray tower 1, so as to realize automatic replacement of the activated carbon 7 without stopping, improve the work efficiency, reduce the equipment maintenance cost, and ensure the stable operation of the waste gas treatment system.

[0051] Referring to Figures 8 to 10 As shown in the figure, the pulling device 54 includes a ball screw sliding table 541 installed on the side of the guide slide rail 51. A limiting mounting bracket 542 is installed on the movable end of the ball screw sliding table 541. An elastic pressing column 543 is installed on the limiting mounting bracket 542. A rotating clamping joint 544 is also installed on the limiting mounting bracket 542. A clamping protrusion 5441 is arranged on the outer side of the rotating clamping joint 544. The pulling device 54 further includes a first rotary driver for driving the rotating clamping joint 544 to rotate.

[0052] The rotating clamping joint 544 is rotationally connected with the limiting mounting bracket 542.

[0053] When the storage frame 4 needs to be pulled and moved, the ball screw sliding table 541 is started, and the movable end of the ball screw sliding table drives the limiting mounting bracket 542 to move towards the storage frame 4. In the process that the limiting mounting bracket 542 gradually approaches the storage frame 4, the elastic pressing column 543 first contacts and is pressed by the storage frame 4, and elastic contraction deformation occurs. This elastic deformation not only plays a buffering role to avoid damage to the device caused by hard collision, but also provides a certain pre-tightening force for subsequent stable connection.

[0054] Meanwhile, the rotating clamping joint 544 is moved to the insertion connecting hole 43 of the storage frame 4 under the driving of the limiting mounting frame 542. In the initial stage of butt joint, the clamping protrusions 5441 on both sides of the rotating clamping joint 544 remain in the transverse position, so as to be smoothly inserted into the insertion connecting hole 43. When the clamping protrusions 5441 are completely inserted into the storage frame 4, the first rotary driver is started, and the output torque is transmitted to the rotating clamping joint 544, so as to drive the rotating clamping joint 544 to rotate around the axis thereof. During the rotating process, the clamping protrusions 5441 are moved to the preset clamping area, and the mechanical clamping is formed between the clamping protrusions 5441 and the structure inside the storage frame 4, so as to realize the firm connection between the rotating clamping joint 544 and the storage frame 4. At this time, the limiting mounting frame 542 and the storage frame 4 form an integral whole through the rotating clamping joint 544, and when the limiting mounting frame 542 continues to move, the storage frame 4 will synchronously move.

[0055] After the successful connection between the rotating clamping joint 544 and the storage frame 4, the ball screw sliding table 541 continues to run in the preset direction, and the movable end drives the limiting mounting frame 542 to move. Since the limiting mounting frame 542 and the storage frame 4 have been connected into an integral whole through the rotating clamping joint 544, the storage frame 4 will move stably along the guide sliding rail 51 under the traction of the limiting mounting frame 542. The accurate guiding effect of the guide sliding rail 51 ensures the straightness and stability of the storage frame 4 during the moving process, avoids the deviation or shaking phenomenon, and ensures that the storage frame 4 can accurately reach the specified position inside the material replacing device 5, so as to provide accurate position guarantee for the subsequent unloading and loading operations.

[0056] When the unloading and loading operations are completed, and the storage frame 4 needs to be pushed back to the corresponding mounting space of the rotating switching plate 3, the first rotary driver is first started to reversely rotate, so as to drive the rotating clamping joint 544 to reset. During the resetting process, the clamping protrusions 5441 are moved out of the clamping area and restored to the initial transverse position, so as to release the mechanical clamping state with the storage frame 4.

[0057] At this time, the elastic pressing column 543 is still in the compressed state, and the elastic restoring force continuously acts on the storage frame 4, so as to generate an outward pushing force on the storage frame 4, so as to avoid the jamming phenomenon during the separation process. Subsequently, the ball screw sliding table 541 drives the limiting mounting frame 542 to move away from the storage frame 4, and the rotating clamping joint 544 is gradually pulled out of the insertion connecting hole 43 under the driving of the limiting mounting frame 542, so as to realize the complete separation from the storage frame 4. The continuous pushing effect of the elastic pressing column 543 plays a key stabilizing role in the entire separation process, so as to ensure the stability and reliability of the separation process, and avoid the equipment failure or operation error caused by unstable separation.

[0058] Referring to Figure 2 and Figure 11As shown, the quantitative sampling device 6 includes a mounting bracket 61 fixedly mounted outside the spray tower 1, the mounting bracket 61 is provided with a material taking hole 611, a linear actuator 62 is mounted on the mounting bracket 61, the output end of the linear actuator 62 is provided with a sampling shaft 63, and the sampling shaft 63 extends to the insertion connection hole 43 through the material taking hole 611.

[0059] In the waste gas treatment process, when it is necessary to detect the adsorption state of the activated carbon 7 in the storage frame 4, the quantitative sampling device 6 enters a working preparation state. At this time, the linear actuator 62 is in an initial position, and the sampling shaft 63 is located in the material taking hole 611 of the mounting bracket 61 and has not yet entered the inside of the spray tower 1. The linear actuator 62 is started, and the sampling shaft 63 moves to the inside of the spray tower 1 along the material taking hole 611 of the mounting bracket 61 under the pushing of the linear actuator 62. With the movement of the sampling shaft 63, the front end thereof gradually approaches the insertion connection hole 43 outside the storage frame 4. When the front end of the sampling shaft 63 reaches the insertion connection hole 43, since the insertion connection hole 43 is internally provided with a material blocking piece 44, a plurality of rubber material blocking strips 45 in the material blocking piece 44 will generate a certain resistance to the sampling shaft 63. However, under the continuous pushing of the linear actuator 62, the sampling shaft 63 continues to move forward, the rubber material blocking strips 45 are elastically deformed under the extrusion of the sampling shaft 63, and an avoiding action is generated, so that the sampling shaft 63 can smoothly pass through the insertion connection hole 43 and enter the inside of the storage frame 4.

[0060] After the sampling shaft 63 enters the inside of the storage frame 4, the sampling shaft 63 is in full contact with the activated carbon 7 in the frame. The sampling shaft 63 enters the activated carbon 7 area to obtain the activated carbon 7 sample.

[0061] After the sampling operation is completed, the linear actuator 62 drives the sampling shaft 63 to exit the storage frame 4 along the original path. During the exit of the sampling shaft 63, when the front end thereof reaches the insertion connection hole 43, the rubber material blocking strips 45 which are elastically deformed under the extrusion are automatically elastically reset under the action of the elastic property thereof. The rubber material blocking strips 45 after the reset are tightly fitted to form an effective blocking structure, which prevents the activated carbon 7 in the storage frame 4 from entering the insertion connection hole 43 and avoids the leakage of the activated carbon 7 or the influence on the subsequent sampling operation. The sampling shaft 63 continues to exit and sequentially passes through the insertion connection hole 43 and the material taking hole 611 and finally returns to the initial position.

[0062] After the sampling shaft 63 returns to the initial position, the staff can conveniently obtain the collected activated carbon 7 sample from the sampling shaft 63. Through laboratory detection and analysis of these samples, the adsorption state of the activated carbon 7 is accurately judged according to key indexes such as the adsorption capacity and the residual amount of pollutants, and it is determined whether the activated carbon 7 needs to be replaced.

[0063] Reference should be made to Figure 11As shown, the outer side of the sampling shaft 63 is provided with a sampling port 631, and the inner side of the sampling shaft 63 is slidably provided with a sampling sleeve 632, and the outer side of the sampling sleeve 632 is provided with a pressing protrusion 6321 which extends outward through the outer wall of the sampling shaft 63, and the sampling sleeve 632 and the sampling shaft 63 are provided with a reset spring,

[0064] In the waste gas treatment process, when it is necessary to detect the adsorption state of the activated carbon 7 in the storage frame 4, the quantitative sampling device 6 enters the working preparation state. At this time, the linear driver 62 is in the initial position, the sampling shaft 63 is located at the sampling hole 611 of the mounting bracket 61, and has not yet entered the inside of the spray tower 1. The sampling port 631 on the outer side of the sampling shaft 63 is blocked by the sampling sleeve 632 on the inside, and the sampling sleeve 632 is kept in a stable position under the action of the reset spring, and the pressing protrusion 6321 on the outer side extends outward through the outer wall of the sampling shaft 63.

[0065] The linear driver 62 is started, and the output end of the linear driver 62 pushes the sampling shaft 63 to move along the sampling hole 611 on the mounting bracket 61 to the inside of the spray tower 1. With the movement of the sampling shaft 63, the front end of the sampling shaft 63 gradually approaches the insertion connection hole 43 on the outer side of the storage frame 4. When the front end of the sampling shaft 63 reaches the insertion connection hole 43, the plurality of rubber blocking strips 45 in the blocking member 44 inside the insertion connection hole 43 generate a certain resistance to the sampling shaft 63. However, under the continuous pushing of the linear driver 62, the sampling shaft 63 continues to move forward, the rubber blocking strips 45 are elastically deformed under the extrusion of the sampling shaft 63, and the sampling shaft 63 can smoothly pass through the insertion connection hole 43 and enter the inside of the storage frame 4.

[0066] During the movement of the sampling shaft 63, the pressing protrusion 6321 of the sampling sleeve 632 has not yet contacted the sampling hole 611, and the sampling sleeve 632 keeps the state of blocking the sampling port 631. When the sampling shaft 63 continues to penetrate, the pressing protrusion 6321 contacts the edge of the sampling hole 611. With the further movement of the sampling shaft 63, the sampling sleeve 632 cannot continue to move due to the blockage of the sampling hole 611, at this time the sampling shaft 63 continues to advance relative to the sampling sleeve 632, compresses the reset spring between the sampling sleeve 632 and the sampling shaft 63, and at the same time the sampling sleeve 632 no longer blocks the sampling port 631, so that the sampling port 631 is opened.

[0067] After the sampling port 631 is opened, the activated carbon 7 sample in the central region of the storage frame 4 falls into the sampling port 631 under the action of gravity. Since the sampling port 631 is in an open state when the sampling shaft 63 enters the activated carbon 7 region, the activated carbon 7 sample in this region can be accurately obtained, the activated carbon 7 in the central region of the storage frame 4 can be effectively extracted, and the detection accuracy is improved.

[0068] After the sampling operation is completed, the linear driver 62 drives the sampling shaft 63 to exit the storage frame 4 along the original path. During the exit of the sampling shaft 63, when the front end thereof reaches the insertion connection hole 43, the rubber blocking strip 45 that has been elastically deformed due to extrusion is automatically elastically reset under the action of its own elastic property. The reset rubber blocking strip 45 is tightly fitted to form an effective blocking structure, preventing the activated carbon 7 in the storage frame 4 from entering the insertion connection hole 43, thereby avoiding leakage of the activated carbon 7 or affecting the subsequent sampling operation.

[0069] Meanwhile, with the exit of the sampling shaft 63, the abutting block 6321 is no longer blocked by the sampling perforation 611, the reset spring is released from the elastic potential energy, and the sampling sleeve 632 is pushed to move to the initial position, gradually closing the sampling port 631, so that the activated carbon 7 sample stays at the sampling port 631. The sampling shaft 63 continues to exit, sequentially passes through the insertion connection hole 43 and the sampling perforation 611, and finally returns to the initial position. After the sampling shaft 63 returns to the initial position, the staff can conveniently obtain the collected activated carbon 7 sample from the sampling port 631 of the sampling shaft 63.

[0070] Referring to Figure 4 and Figure 5 As shown, the area flow blocking device 2 includes a fixed frame 21 fixedly installed inside the spray tower 1, the inside of the fixed frame 21 is provided with an airflow channel, the inside of the airflow channel is rotatably installed with a turnover flow blocking plate 22, and the area flow blocking device 2 further includes a second rotary driver 23 driving the turnover flow blocking plate 22 to rotate.

[0071] After the spray tower 1 is started, the waste gas to be treated enters the tower, and the atomizing spray system is opened to perform atomizing spray treatment on the waste gas. At this time, the rotary switching plate 3 cooperates with the activated carbon 7 inside to normally filter the waste gas, and the area flow blocking device 2 is in a non-working state. The fixed frame 21 is fixedly installed inside the spray tower 1, the airflow channel inside the fixed frame 21 remains unblocked, and the turnover flow blocking plate 22 is in a vertical state. The waste gas can smoothly rise through the airflow channel and pass through the storage frame 4 on the rotary switching plate 3 to fully contact the activated carbon 7 therein, the pollutants in the waste gas are adsorbed and filtered by the activated carbon 7, and the purification treatment of the waste gas is realized.

[0072] As the activated carbon 7 is used for a long time, its adsorption effect gradually decreases. When the activated carbon 7 sample is detected and analyzed by the quantitative sampling device 6, it is determined that the activated carbon 7 needs to be replaced, and the system starts the automatic replacement process. At this time, the area blocking device 2 enters the working preparation state, and the second rotary driver 23 starts to operate. The second rotary driver 23 drives the turnover blocking plate 22 to rotate, and gradually changes from the vertical state to the horizontal state. When the turnover blocking plate 22 rotates to the horizontal state, its plate completely blocks the airflow channel inside the fixed frame 21. At this time, the area corresponding to the activated carbon 7 to be replaced is effectively shielded by the turnover blocking plate 22, and the exhaust gas cannot flow upward from this area, thereby preventing the exhaust gas from passing through the area of the activated carbon 7 to be replaced.

[0073] Specific working principle:

[0074] After the spray tower 1 is started, the waste gas to be treated enters the tower, and at the same time the atomizing spray system is opened to treat the waste gas by atomizing spray. The waste gas and the atomizing spray liquid will pass through the rotating switch plate 3 installed on the spray tower 1 in the rising process. The rotating switch plate 3 is internally provided with a plurality of installation spaces, and each installation space is provided with a storage frame 4 for storing activated carbon 7. When the waste gas passes through the rotating switch plate 3, the pollutants in the waste gas will be adsorbed and filtered by the activated carbon 7, thereby achieving the purpose of purifying the waste gas.

[0075] With the long-time use of the activated carbon 7, the adsorption effect will gradually decrease. In order to accurately determine the adsorption state of the activated carbon 7, the staff can use the quantitative sampling device 6 installed on the side of the rotating switch plate 3 to quantitatively extract the activated carbon 7 sample in the storage frame 4. By detecting and analyzing the extracted activated carbon 7 sample, according to the key indicators such as adsorption capacity and pollutant residue, it can be accurately determined whether the activated carbon 7 has reached the saturation state and whether it needs to be replaced. Compared with the traditional fixed period replacement method, this detection method can more accurately reflect the real use of the activated carbon 7, effectively avoid the waste of activated carbon 7 caused by premature replacement, and reduce the cost of waste gas treatment. If the detection result shows that the activated carbon 7 needs to be replaced, the automatic replacement process is started. First, the area blocking device 2 installed below the rotating switch plate 3 is started, which blocks the area where the activated carbon 7 to be replaced, preventing the waste gas from rising from this area, ensuring that the waste gas does not leak during the replacement process, and avoiding interference with the replacement operation. Then, the material replacement device 5 installed on the side of the rotating switch plate 3 starts to work, extracts the storage frame 4 containing the activated carbon 7 to be replaced from the rotating switch plate 3, and moves it to the inside of the material replacement device 5. In the material replacement device 5, the failed activated carbon 7 is discharged, and at the same time, new activated carbon 7 is automatically loaded into the storage frame 4. After the loading is completed, the material replacement device 5 pushes the storage frame 4 containing the replaced activated carbon 7 back to the rotating switch plate 3. Then, the rotating switch plate 3 rotates, driving the un-replaced storage frame 4 to switch positions, so that the next storage frame 4 to be replaced is in the corresponding position of the material replacement device 5. The material replacement device 5 repeats the above replacement steps to replace all the activated carbon 7 in the rotating switch plate 3.

[0076] When all the activated carbon 7 in the rotating switch plate 3 is replaced, the area blocking device 2 is opened, restoring the normal upward channel of the waste gas from all areas, and restoring the normal filtering operation state. The entire activated carbon 7 replacement process does not need to stop the operation of the spray tower 1, realizing automatic replacement without stopping, effectively improving the work efficiency, reducing the adverse effects on the stability and service life of the equipment caused by frequent start and stop of the equipment, and ensuring the normal production of the enterprise.
