TECHNICAL FIELD

The user can effectively deliver the catalyst to the catalytic tank to realize further catalytic treatment of waste gas when delivering the catalyst through the conveying pipe and the fan to the feed pipe. The treated waste gas can be effectively delivered outward to effectively improve the adsorption and catalytic effect of waste gas, realize the integrated adsorption and catalytic effect of waste gas, and further reduce the waste gas delivery process to effectively avoid the situation that the waste gas treatment effect is greatly reduced due to insufficient waste gas treatment and incomplete treatment during the conveying process, thereby effectively overcoming the shortcomings of the prior art.

[0009] Further, the number of the installation frames is two, and the two installation frames are symmetrically and staggeredly rotationally connected in the adsorption channel, and a second driving assembly for driving the two installation frames to synchronously rotate is connected to one side of the adsorption channel.
[0010] Further, the second driving assembly comprises a second rotating shaft connected to the rotating cam, a second bevel gear is connected to the other end of the second rotating shaft, a third bevel gear is meshingly connected between the two second bevel gears, a third rotating shaft is connected to the third bevel gear, and a third servo motor for driving the third rotating shaft to rotate is arranged on one side of the adsorption channel.
[0011] Further, one end of the third rotating shaft extends to the outside of the adsorption channel and is connected with a synchronous wheel, a transmission disc is further arranged on the outside of the adsorption channel, the driving shaft of the third servo motor is connected with the transmission disc through a shaft coupling, a plurality of transmission blocks are circumferentially and equidistantly arranged on the outside of the transmission disc, the plurality of transmission blocks form an annular transmission member, and an elastic synchronous belt is transmissionally connected between the annular transmission member and the synchronous wheel.
[0012] Further, the transmission disc is rotationally connected with a connecting gear ring, a plurality of mounting gears are arranged in a circumferential array on the transmission disc, the mounting gears are in meshing connection with the connecting gear ring, a transmission rack is connected to one side of the mounting gears, one end of the transmission rack extends to the outside of the transmission disc and is connected with a transmission block, and a second servo motor is connected to the transmission disc to drive one of the mounting gears to rotate.

[0014] Further, a screw rod is connected to the mounting frame, the rotating plate is sleeved on the screw rod, and a nut is threadedly connected to the screw rod to limit the rotating plate.
[0015] Further, at least two filter frames are connected in the filter box.
[0016] Compared with the prior art, the present application has the following advantages: 1. By controlling the first servo motor, the first bevel gear and the bevel gear ring are meshed, and the guide rod and the guide groove are matched to drive the active carbon storage frame to rotate. The area of the active carbon which is not fully used or has a lower temperature is turned to the exhaust gas path to increase the contact area and time, and the high-temperature saturated area is allowed to dissipate heat and reduce the temperature to restore the performance. This setting effectively compensates for the decrease in active carbon adsorption efficiency caused by high temperature, improves the adsorption capacity of the device to VOCs under high temperature conditions, and ensures that the exhaust gas treatment effect is not affected by temperature fluctuations.
[0017] 2. The first servo motor drives the active carbon storage frame to rotate at a slow speed. On the one hand, the position of the active carbon is adjusted to allow some areas to first contact the exhaust gas with low humidity to reduce water vapor adsorption; on the other hand, the angle is adjusted during rotation to facilitate the sliding of water vapor. This setting improves the adsorption capacity of high-humidity exhaust gas.
[0018] 3. In the adsorption channel, the rotating cam drives the guide rod to make a circular motion at the mounting frame connected to the mounting frame, intermittently pushes the rotating plate to rotate, and then the mounting frame and the internal active carbon storage frame realize intermittent rotation. When the rotating plate is stationary, the exhaust gas passes through the conventional path; when the rotating plate rotates, the active carbon storage frame forms a new flow guide surface. This setting can break the local airflow dead angle that may exist in the exhaust gas, avoid the exhaust gas from not being able to fully contact the active carbon due to the fixed flow channel. At the same time, intermittent rotation avoids the single area of the active carbon from being in a high-load adsorption state for a long time. Because the active carbon in different areas will be periodically rotated to contact the exhaust gas, the use of the active carbon is more balanced, thereby prolonging the effective service life of the active carbon.
[0019] 4、The two symmetrical staggered mounting frames in the adsorption channel are synchronously driven by the third servo motor, greatly increasing the adsorption area and enabling efficient processing of large-volume waste gas. At the same time, the second servo motor can change the mounting frame rotation speed by adjusting the transmission ratio, accurately adapting to the demand for active carbon storage frame rotation speed under different working conditions.

DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.
[0023] Please refer to Figures 1-10 The present application provides a technical solution: an intelligent adsorption treatment integrated device for VOCs waste gas treatment, comprising a mounting base 1, a filter box 2, an adsorption channel 3 and a conveying air duct 4 connected in sequence along the air inlet direction and arranged on the top of the mounting base 1; The mounting frame 5 is connected in the adsorption channel 3, the connecting column 6 is arranged in the mounting frame 5, a plurality of first rotating shafts 8 are rotationally connected to the connecting column 6 in a circumferential array and are equally spaced around the central axis of the connecting column 6, one end of the first rotating shaft 8 extends to the outside of the mounting frame 5, the activated carbon storage frame 7 is connected to the first rotating shaft 8, the first driving assembly for driving the activated carbon storage frame 7 to rotate is arranged on the outside of the mounting frame 5, the temperature and humidity sensor 39 is connected in the filter box 2, and the temperature and humidity sensor 39 is electrically connected with the driving assembly In specific implementation, the VOCs waste gas to be treated passes through the filter box 2, the adsorption channel 3 and the conveying air duct 4 in sequence along the air inlet direction. The temperature and humidity sensor 39 arranged in the filter box 2 continuously monitors the temperature and humidity data of the waste gas. In the mounting frame 5 of the adsorption channel 3, a plurality of first rotating shafts 8 are rotationally connected to the connecting column 6, and the activated carbon storage frame 7 is arranged on each first rotating shaft 8. When the temperature and humidity sensor 39 detects that the temperature and humidity of the waste gas change, the corresponding electrical signal is transmitted to the first driving assembly, and the first driving assembly drives the first rotating shaft 8 to rotate, thereby driving the activated carbon storage frame 7 to rotate, so as to adjust the contact state and area of the activated carbon and the waste gas.
[0024] Please refer to Figures 1-10 The first driving assembly comprises a connecting piece 11 connected to one end of the first rotating shaft 8, the connecting piece 11 is located outside the mounting frame 5, the first guiding groove 12 is formed in the connecting piece 11, the mounting ring 9 is rotationally connected to the outside of the mounting frame 5, the mounting ring 9 is coaxially arranged with the mounting frame 5, the bevel gear ring 13 is connected to the mounting ring 9, the connecting plate 14 is connected to the outside of the mounting frame 5, the first bevel gear 15 is rotationally connected in the connecting plate 14, the first bevel gear 15 is meshingly connected with the bevel gear ring 13, the first servo motor 16 is connected to one side of the connecting plate 14, the first servo motor 16 is connected with the first bevel gear 15 through the shaft coupling, a plurality of first guiding rods 10 are arranged on the outer surface of the mounting ring 9 in a circumferential array and are equally spaced, and the first guiding rods 10 are slidingly connected in the first guiding groove 12.
[0025] It should be noted that one side of the filter box 2 can be connected with a control device composed of a single piece, which is electrically connected with the first servo motor 16 and the temperature and humidity sensor 39, which is a prior art and will not be described in detail here.
[0026] In specific implementation, when the first servo motor 16 is started, the first bevel gear 15 is driven to rotate through the shaft coupling. Since the first bevel gear 15 is in meshing with the bevel gear ring 13 on the mounting ring 9, the rotation of the first bevel gear 15 will drive the mounting ring 9 to rotate around the mounting frame 5. The mounting ring 9 is distributed with a plurality of first guide rods 10, which are in sliding fit with the first guide grooves 12 opened on the connecting piece 11. The connecting piece 11 is connected to one end of the first rotating shaft 8, so when the mounting ring 9 rotates, the first guide rods 10 slide in the first guide grooves 12, thereby driving the first rotating shaft 8 to rotate, and finally driving the activated carbon storage frame 7 to rotate. In summary, when the temperature and humidity sensor 39 detects that the temperature of the exhaust gas rises, it means that the adsorption performance of the activated carbon will decrease due to high temperature. At this time, the temperature and humidity sensor 39 transmits the signal of temperature rise to the control device. After receiving the signal, the control device controls the first servo motor 16 to start and rotate according to the preset program. The first servo motor 16 drives the first bevel gear 15 to rotate, thereby driving the mounting ring 9 to rotate. Through the cooperation of the first guide rods 10 and the first guide grooves 12, the first rotating shaft 8 is driven to rotate, and the activated carbon storage frame 7 is driven to rotate. The purpose of rotation is to rotate the area of activated carbon that is not fully used or has relatively low temperature to the path of exhaust gas flow, increase the contact area and contact time of activated carbon and exhaust gas, and also allow the area of activated carbon that has been saturated with adsorption under high temperature to temporarily leave the exhaust gas flow path, so as to have time to cool down and restore part of the adsorption performance, so as to make up for the decrease in adsorption efficiency caused by high temperature. When the temperature and humidity sensor 39 detects that the humidity of the exhaust gas rises, it means that water vapor will occupy the adsorption sites of activated carbon, affecting the adsorption effect of VOCs. The temperature and humidity sensor 39 transmits the signal of humidity rise to the control system, and the control system controls the first servo motor 16 to start. The first servo motor 16 drives the activated carbon storage frame 7 to rotate through the transmission structure. The rotation mode can be to rotate the activated carbon storage frame 7 at a slower speed to allow the exhaust gas to have more sufficient contact time with the activated carbon, and also to adjust the position of the activated carbon, so that part of the activated carbon area is exposed to exhaust gas with relatively low humidity, reducing the adsorption of water vapor and improving the adsorption capacity of VOCs. In addition, during the rotation process, the activated carbon storage frame 7 can also form a certain angle, so that water vapor is more easily caused to slide off the surface of the activated carbon under the action of gravity, reducing the occupation of the adsorption sites by water vapor.
[0027] Please refer to Figures 1-10, the mounting frame 5 is connected with a mounting rack 17, the mounting rack 17 is detachably connected with a rotating plate 18, a plurality of second guide grooves 19 are arranged in the circumferential array on the rotating plate 18, the mounting rack 17 is rotatably connected with a rotating cam 20, and the free end of the rotating cam 20 is connected with a second guide rod 21, wherein, When the second guide rod 21 rotates, the second guide rod 21 can intermittently slide in the plurality of second guide grooves 19 to drive the rotating plate 18 to rotate intermittently.
[0028] In specific implementation, when the rotating cam 20 is driven to rotate, the second guide rod 21 at the free end of the rotating cam 20 moves in a circumferential direction. In this process, the second guide rod 21 will intermittently enter different second guide grooves 19. When the second guide rod 21 enters the second guide groove 19, the rotating plate 18 is pushed to rotate by a certain angle; when the second guide rod 21 leaves the second guide groove 19, the rotating plate 18 stops rotating. Such a cycle realizes the intermittent rotation of the rotating plate 18. Since the rotating plate 18 has a certain connection relationship with the mounting frame 5, the intermittent rotation of the rotating plate 18 further drives the mounting frame 5 and the activated carbon storage frame 7 in the mounting frame 5 to rotate intermittently; The arrangement makes the exhaust gas pass through the conventional path when the rotating plate 18 is stationary, and when the rotating plate 18 suddenly rotates by an angle, the activated carbon storage frame 7 forms a new flow guide surface, so that the flow direction of the exhaust gas changes, which helps to break the local airflow dead angle, and the intermittent rotation can avoid the rapid saturation of activated carbon in a single area due to long-term high-load adsorption, thereby prolonging the effective service life of the activated carbon.
[0029] Please refer to Figures 1-10 The number of the mounting frame 5 is two, and the two mounting frames 5 are symmetrically and staggeredly connected in the adsorption channel 3. One side of the adsorption channel 3 is connected with a second driving assembly for driving the two mounting frames 5 to rotate synchronously.
[0030] In specific implementation, the two mounting frames 5 rotate synchronously, which greatly increases the adsorption area and improves the adsorption efficiency compared with a single mounting frame 5, thereby facilitating the treatment of large-volume exhaust gas.
[0031] Please refer to Figures 1-10 The second driving assembly includes a second rotating shaft 22 connected to the rotating cam 20, a second bevel gear 23 connected to the other end of the second rotating shaft 22, a third bevel gear 24 meshingly connected between the two second bevel gears 23, and a third rotating shaft 25 connected to the third bevel gear 24.

[0032] In specific implementation, the third servo motor 34 is started to drive the third rotating shaft 25 to rotate, the third bevel gear 24 on the third rotating shaft 25 meshes with the two second bevel gears 23, thereby driving the two rotating cams 20 to rotate synchronously, and the synchronous driving of the two mounting frames 5 is realized.
[0033] Please refer to Figures 1-10 , one end of the third rotating shaft 25 extends to the outside of the adsorption channel 3 and is connected with a synchronous wheel 26, the outside of the adsorption channel 3 is also provided with a transmission disc 27, the drive shaft of the third servo motor 34 is connected with the transmission disc 27 through a shaft coupling, the outside of the transmission disc 27 is slidably provided with a plurality of transmission blocks 31 arranged in a circumferential array, the plurality of transmission blocks 31 constitute an annular transmission member, and the annular transmission member is in transmission connection with the synchronous wheel 26 through an elastic synchronous belt 32.
[0034] In specific implementation, the drive shaft of the third servo motor 34 drives the transmission disc 27 to rotate, the plurality of transmission blocks 31 on the transmission disc 27 constitute an annular transmission member, and the annular transmission member is in transmission connection with the synchronous wheel 26 through the elastic synchronous belt 32, the synchronous wheel 26 is connected at one end of the third rotating shaft 25, so as to realize the transmission of power from the third servo motor 34 to the third rotating shaft 25.
[0035] Please refer to Figures 1-10 , the transmission disc 27 is rotatably connected with a connecting gear ring 28, a plurality of mounting gears 29 arranged in a circumferential array are rotatably connected in the transmission disc 27, the mounting gears 29 are in meshing with each other with the connecting gear ring 28, a transmission rack 30 is connected at one side of the mounting gears 29, one end of the transmission rack 30 extends to the outside of the transmission disc 27 and is connected with the transmission blocks 31, and the transmission disc 27 is connected with a second servo motor 33 for driving one of the mounting gears 29 to rotate.
[0036] In specific implementation, the second servo motor 33 drives one of the mounting gears 29 to rotate, the mounting gears 29 are in meshing with the connecting gear ring 28, and simultaneously drive other mounting gears 29 to rotate, the mounting gears 29 are in meshing with the transmission rack 30, so that the transmission rack 30 drives the transmission blocks 31 to slide on the outside of the transmission disc 27, so as to change the transmission radius of the annular transmission member, and the transmission ratio between the transmission disc 27 and the synchronous wheel 26 can be flexibly adjusted. When the flow, temperature or humidity of the exhaust gas changes greatly, the transmission ratio can be adjusted, the rotating speed of the third rotating shaft 25 is changed, and then the rotating speed of the two mounting frames 5 is adjusted, so that the device can more accurately adapt to the demand for the rotating speed of the activated carbon storage frame 7 under different working conditions, and the adsorption treatment effect of the exhaust gas with different temperature and humidity and flow is further improved.
[0037] Please refer to Figures 1-10 , the outside of the mounting frame 5 is connected with a support block 35, and the mounting ring 9 is slidably connected on the support block 35.
[0038] In specific implementation, the support block 35 on the outside of the mounting frame 5 supports and guides the mounting ring 9, and the mounting ring 9 can stably slide on the support block 35.
[0039] Please refer to Figures 1-10The mounting frame 17 is connected with a screw rod 36, the rotating plate 18 is sleeved on the screw rod 36, and the screw rod 36 is threadedly connected with a nut 37 for limiting the rotating plate 18.
[0040] In specific implementation, the rotating plate 18 is sleeved on the screw rod 36 of the mounting frame 17, and the rotating plate 18 is limited and fixed through the threaded connection of the nut 37 on the screw rod 36. This arrangement facilitates the disassembly and replacement of the rotating plate 18 and the adjustment of the rotating frequency of the mounting frame 5.
[0041] Please refer to Figures 1-10 The filter box 2 is connected with at least two filter frames 38.
[0042] In specific implementation, the filter box 2 is connected with at least two filter frames 38. The exhaust gas is filtered by the filter frames 38 before entering the adsorption channel 3. The multiple filter frames 38 can perform multi-stage filtration on the particulate matters, impurities and the like in the exhaust gas, effectively purifying the exhaust gas. These impurities are prevented from entering the adsorption channel 3, preventing the clogging of the activated carbon storage frame 7 or affecting the adsorption effect of the activated carbon.
[0043] Working principle: The VOCs exhaust gas to be treated enters from above the mounting base 1 at the bottom of the device, first enters the filter box 2. The filter box 2 is connected with at least two filter frames 38, and the exhaust gas passes through these filter frames 38 in sequence. The filter frames 38 perform multi-stage filtration on the particulate matters, impurities and the like in the exhaust gas, effectively purifying the exhaust gas, avoiding the impurities from entering the subsequent adsorption channel 3, preventing the clogging of the activated carbon storage frame 7 or affecting the adsorption effect of the activated carbon. At the same time, in the filter box 2, a temperature and humidity sensor 39 continuously monitors the temperature and humidity data of the exhaust gas and transmits these data to a control device composed of a single chip in real time.
[0044] The pre-processed exhaust gas enters the adsorption channel 3. In the mounting frame 5 in the adsorption channel 3, a plurality of first rotating shafts 8 are rotatably connected on the connecting column 6, and the activated carbon storage frame 7 is connected on the first rotating shaft 8. When the temperature and humidity sensor 39 detects that the temperature and humidity of the exhaust gas changes and transmits a signal to the control device, the control device controls according to the preset program. If the temperature of the exhaust gas is detected to be increased, the control device controls the first servo motor 16 to start and rotate according to the program. The first servo motor 16 drives the first bevel gear 15 to rotate through the shaft coupling, and the first bevel gear 15 is engaged with the bevel gear ring 13 on the mounting ring 9 to drive the mounting ring 9 to rotate around the mounting frame 5. The first guide rod 10 on the mounting ring 9 slides in the first guide groove 12 of the connecting piece 11, drives the first rotating shaft 8 to rotate, and drives the activated carbon storage frame 7 to rotate, so that the area of the activated carbon which is not fully used or has relatively low temperature is rotated to the exhaust gas flow path, the contact area and time are increased, and at the same time, the area of the activated carbon which is saturated after adsorption at high temperature is away from the flow channel to dissipate heat and reduce temperature. If the humidity of the exhaust gas is detected to be increased, the control device also controls the first servo motor 16 to start, and drives the activated carbon storage frame 7 to rotate at a slow speed through the transmission structure, adjusts the position of the activated carbon, so that part of the area contacts the exhaust gas with relatively low humidity first, reduces the water vapor adsorption, improves the adsorption capacity of VOCs, and the angle adjustment during rotation is beneficial to the sliding of water vapor; In the adsorption channel 3, the rotating cam 20 rotates on the mounting frame 17 connected on the mounting frame 5 under the action of power. The second guide rod 21 at the free end of the rotating cam 20 moves in a circular motion, intermittently enters the second guide groove 19 on the rotating plate 18, drives the rotating plate 18 to rotate intermittently, and further drives the mounting frame 5 and the activated carbon storage frame 7 inside to rotate intermittently. When the rotating plate 18 is stationary, the exhaust gas passes through the conventional path; when the rotating plate 18 rotates, the activated carbon storage frame 7 forms a new flow surface to change the flow direction of the exhaust gas, breaks the local airflow dead angle, avoids long-term high-load adsorption of the activated carbon in a single area, and prolongs the service life of the activated carbon; The two mounting frames 5 are symmetrically and alternately connected in the adsorption channel 3. When the third servo motor 34 is started, the third rotating shaft 25 is rotated, the third bevel gear 24 on the third rotating shaft 25 meshes with the two second bevel gears 23, and the two rotating cams 20 are synchronously rotated to realize the synchronous driving of the two mounting frames 5. The synchronous rotation of the two mounting frames 5 greatly increases the adsorption area and improves the adsorption efficiency, and facilitates the treatment of large air volume waste gas. At the same time, when the flow, temperature or humidity of the waste gas changes greatly, the second servo motor 33 drives the mounting gear 29 to rotate, changes the transmission radius of the ring-shaped transmission member through cooperation with the connecting gear ring 28 and the transmission rack 30, flexibly adjusts the transmission ratio between the transmission disc 27 and the synchronous wheel 26, changes the rotating speed of the third rotating shaft 25, adjusts the rotating speed of the two mounting frames 5, and makes the device more accurately adapt to the demand of the rotating speed of the activated carbon storage frame 7 in different working conditions, further improves the adsorption treatment effect. The supporting block 35 outside the mounting frame 5 supports and guides the mounting ring 9, ensures the stable sliding of the mounting ring 9, the screw rod 36 and the nut 37 on the mounting frame 17 can limit and fix the rotating plate 18, facilitate disassembly and replacement of the rotating plate 18 to adjust the rotating frequency of the mounting frame 5, After the waste gas is fully treated in the adsorption channel 3, it is discharged from the device through the conveying air duct 4, and the intelligent adsorption treatment process of the VOCs waste gas is completed.
