The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0039] like Figures 1 to 10As shown, the VOCs tail gas treatment device of the present invention comprises a tower body 1, a material frame 2, a flow equalizing frame 3, a water inlet pipe 11 and a water outlet pipe 12, wherein the water inlet pipe 11 and the water outlet pipe 12 are respectively arranged at both ends of the tower body 1, the material frame 2 is arranged in the tower body 1, a filler for treating VOCs tail gas is placed in the material frame 2, the flow equalizing frame 3 is arranged between the material frame 2 and the water inlet pipe 11, and a vent pipe 13 is arranged at the bottom of the tower body 1. When treating the VOCs tail gas, the VOCs tail gas is introduced into the tower body 1 through the vent pipe 13, and at the same time, the water is sprayed from the water inlet pipe 11, and the water passes through the flow equalizing frame 3 and the material frame 2 in sequence, and is finally discharged through the water outlet pipe 12, and at the same time, when the VOCs tail gas passes through the material frame 2, it is treated by the filler in the material frame 2.

[0040] Reference Figures 2 to 4 The material frame 2 is rotatably arranged in the tower body 1. A driving member 4 is arranged on the tower body 1. The driving member 4 is connected to the material frame 2 to drive the material frame 2 to rotate. A partition 5 and an intermediate rod 6 are arranged in the material frame 2. The intermediate rod 6 is coaxially fixedly connected to the material frame 2. Multiple partitions 5 are arranged around the intermediate rod 6. The multiple partitions 5 divide the interior of the material frame 2 into multiple filling cavities for placing fillers. The fillers are placed in the multiple filling cavities respectively. The partition 5 is rotatably arranged around the intermediate rod 6. An elastic member 61 is arranged on the intermediate rod 6. The elastic member 61 can be set as a spring. One end of the spring is connected to the partition 5 and the other end is connected to the intermediate rod 6. The elastic member 61 is used to drive the distance between two adjacent partitions 5 to be the same, that is, the elastic member 61 is used to drive multiple partitions 5 to be distributed at equal distances around the intermediate rod 6. A control member 7 is arranged in the tower body 1. The control member 7 is used to drive the partition 5 to rotate relative to the intermediate rod 6.

[0041] When the filler needs to be cleaned, the driving member 4 drives the material frame 2 to rotate, and the rotation of the material frame 2 drives the partition 5 to rotate to the control member 7, and the control member 7 drives the partition 5 to rotate relative to the middle rod 6, that is, the partition 5 at the control member 7 stops rotating, so as to increase the distance between two adjacent partitions 5, thereby expanding the corresponding filling cavity, and the water inlet pipe 11 corresponds to the expanded filling cavity. After the filling cavity is expanded, the gap between the fillers filled therein increases accordingly or the fillers are made in a loose state, so as to increase the contact area with the fillers during flushing, remove impurities therein, and improve the cleaning effect of the fillers.

[0042] Reference Figures 2 to 4 The driving member 4 includes a power member 41, a gear 42 and a ring gear 43. The ring gear 43 is coaxially sleeved on the outside of the material frame 2. The power member 41 can be set as a motor. The power member 41 is set on the tower body 1. The gear 42 is set at the output end of the power member 41. The gear 42 is meshed with the ring gear 43. The power member 41 drives the ring gear 43 to rotate through the gear 42, thereby driving the material frame 2 to rotate.

[0043] Reference Figures 2 to 4The control member 7 includes a stopper 71, a stopper 72 and an elastic member 73. The stopper 71 is arranged on the inner wall of the tower body 1, and the stopper 71 is arranged in the vertical direction. The stopper 72 is arranged at one end of the partition 5 away from the intermediate rod 6, and the stopper 72 is slidably arranged on the partition 5 in the direction toward the stopper 71. The elastic member 73 can be set as a spring, and the spring is arranged in the partition 5 and connected with the stopper 72, that is, the elastic member 73 is used to drive the stopper 72 to move to the outside of the partition 5. A through groove 21 is provided on the material frame 2, and the stopper 72 extends through the through groove 21 to the outside of the through groove 21. A slope 721 is provided on the side of the stopper 72, and the stopper 72 abuts against the stopper 71 through the slope 721.

[0044] Reference Figures 2 to 4 When the material frame 2 rotates, the block 72 is driven to rotate accordingly. When the block 72 rotates to the stop rod 71, the inclined surface 721 contacts the stop rod 71, and the partition 5 stops rotating and rotates relative to the material frame 2. At the same time, the block 72 slides in the through groove 21 to expand the size of the corresponding filling cavity and clean the filler in the filling cavity. After cleaning, the material frame 2 continues to rotate, and the block 72 gradually moves into the partition 5 under the action of the inclined surface 721 and compresses the elastic part 2 73 until the block 72 is separated from the stop rod 71. The partition 5 rotates to the initial position under the action of the elastic part 1 61 to restore the size of the filling cavity. Repeat the above operation to clean multiple filling cavities in sequence.

[0045] Reference Figure 2 and Figure 3 , multiple groups of partitions 5 are arranged in the vertical direction, and each group is composed of multiple partitions 5 arranged in the same plane. An intermediate plate 22 is arranged in the material frame 2, and multiple intermediate plates 22 are arranged, and the intermediate plates 22 are arranged between each two adjacent groups of partitions 5. Through holes are opened on the intermediate plates 22 so that water can flow through the through holes. The intermediate pipe penetrates the intermediate plate 22 and is connected to multiple groups of partitions 5 at the same time. The blocking rod 71 is arranged along the arrangement direction of the multiple groups of partitions 5. When the material frame 2 rotates, the partitions 5 in the multiple groups of partitions 5 are adjusted at the same time through the blocking rod 71, and then the size of the filling cavity at the same position is adjusted, so that the multiple enlarged filling cavities are in the same vertical direction, so that the fillers in the multiple filling cavities can be cleaned at the same time.

[0046] Reference Figure 4 and Figure 5A push rod 51 is provided through the partition 5, and the push rod 51 is slidably provided in the direction toward the middle rod 6. The end of the push rod 51 also extends to the outside of the material frame 2 through the through slot 21. A guide rod 52 is provided on the inner wall of the tower body 1. The guide rod 52 is spaced apart from the stop rod 71, and the guide rod 52 is arranged in an arc shape around the material frame 2. A second inclined surface 521 is provided at one end of the guide rod 52 close to the stop rod 71. After the filler in the corresponding filling cavity is cleaned and the partition 5 rotates to the initial position, the material frame 2 drives the partition 5 to continue to rotate. When the push rod 51 rotates to the guide rod 52, it gradually abuts against the guide rod 52 under the action of the second inclined surface 521, and drives the push rod 51 to move. After the push rod 51 abuts against the guide rod 52, the end of the push rod 51 abuts against the side of the middle rod 6, fixing the partition 5 relative to the middle rod 6, reducing the phenomenon of rotation deviation when the remaining partitions 5 rotate relative to the middle rod 6, and improving the overall stability.

[0047] In this embodiment, the end of the top rod 51 is arranged to be spaced apart from the inner wall of the tower body 1, and the distance between the top rod 51 and the tower body 1 is greater than the thickness of the blocking rod 71, so as to prevent the top rod 51 from contacting the baffle when rotating with the partition 5, and reduce the phenomenon that the blocking rod 71 interferes with the rotation of the top rod 51. In other embodiments, a ball can be rotatably arranged at one end of the top rod 51 close to the guide rod 52, and the top rod 51 abuts against the guide rod 52 through the ball to reduce the friction between the top rod 51 and the guide rod 52, so that the top rod 51 rotates with the partition 5 and fixes the position of the partition 5 at the same time.

[0048] Reference Figure 4 and Figure 5 A plurality of auxiliary rods 62 are arranged on the middle rod 6, and the plurality of auxiliary rods 62 and the plurality of partitions 5 are arranged in a one-to-one correspondence. The auxiliary rods 62 are arranged in an arc shape around the middle rod 6, and the partition 5 and the auxiliary rods 62 are slidably matched, that is, the partition 5 is connected to the middle rod 6 through the auxiliary rods 62, and a plurality of elastic members 61 are arranged corresponding to the plurality of auxiliary rods 62, that is, the plurality of elastic members 61 and the plurality of partitions 5 are arranged in a one-to-one correspondence, so that each partition 5 is relatively independent when rotating, thereby reducing the phenomenon of interference with other partitions 5 when the partition 5 rotates.

[0049] Reference Figure 1 and Figure 6The flow equalizing frame 3 is arranged between the water inlet pipe 11 and the material frame 2, and the flow equalizing frame 3 includes a flow equalizing plate 31, a collecting frame 32 and a guide frame 33. The collecting frame 32 and the flow equalizing plate 31 are spaced apart on the side away from the ground, and the guide frame 33 is arranged in the vertical direction. An opening is provided at the bottom of the guide frame 33, and the guide frame 33 is arranged in the collecting frame 32, and its open end passes through the collecting frame 32 and cooperates with the flow equalizing plate 31.

The auxiliary frame 331 has the same structure as the guide frame 33, and the auxiliary frame 331 and the guide frame 33 are evenly spaced in the collecting frame 32.

[0050] Reference Figure 6 , water enters the collecting frame 32 through the water inlet pipe 11. As the water level in the collecting frame 32 gradually rises to the inlet 8, the water enters the guide frame 33 through the inlet 8, and then flows out through the equalizing hole 1 311. At the same time, under the action of the equalizing hole 2 337, the water flows to the outside of the guide frame 33 and enters other positions on the equalizing plate 31, and then flows out through the equalizing hole 1 311 at other positions on the equalizing plate 31, so that the water passes through the equalizing plate 31 evenly, so that the water can fully contact the filler in the material frame 2, thereby improving the treatment effect of the exhaust gas.

[0051] Reference Figures 6 to 9 In order to facilitate the cleaning of the filler during cleaning, a guide plate 332 is arranged in the guide frame 33. The guide plate 332 is arranged at the center of the guide frame 33 to divide the interior of the guide frame 33 into two areas. The inlet 8 includes an inlet 1 81 and an inlet 2 82. The inlet 1 81 and the inlet 2 82 are respectively arranged on both sides of the guide plate 332. The distance between the bottom of the inlet 2 82 and the collection frame 32 is smaller than the distance between the inlet 1 81 and the collection frame 32. A slide plate 9 is slidably arranged on the outside of the guide frame 33. The slide plate 9 slides toward the direction of the inlet 2 82. The slide plate 9 can slide to a specified position to cover the inlet 2 82. The inlet 2 82 corresponds to the enlarged filling cavity.

[0052] Reference Figures 6 to 9 In the initial state, the slide plate 9 slides to be flush with the bottom of the first inlet 81, and the water in the collection frame 32 enters the collection frame 32 through the first inlet 81 and the second inlet 82 at the same time. When the filler needs to be cleaned, the slide plate 9 is separated from the second inlet 82. At this time, the water in the collection frame 32 first enters the guide frame 33 through the second inlet 82 with a lower bottom, and then enters the expanded filling cavity through the guide frame 33 and the equalizing hole 1 311, so that the water is concentrated to clean the filler in the filling cavity, thereby improving the cleaning effect of the filler.

[0053] Reference Figures 6 to 9 A driving rod 333 is rotatably arranged in the guide frame 33, and a threaded groove 335 is opened on the driving rod 333.

[0054] Reference Figures 6 to 9 In the initial state, the elastic member four 93 drives the slide plate 9 to be at the entrance two 82, the driving motor 94 drives the driving rod 333 to rotate, the driving rod 333 drives the push rod 91 to move, the push rod 91 moves to abut against the inclined surface three 92, and at the same time drives the slide plate 9 to slide in the direction away from the entrance two 82 until the slide plate 9 is separated from the entrance two 82, so as to adjust the position of the slide plate 9.

[0055] Reference Figures 6 to 9 A cover plate 95 is provided on the slide plate 9. The cover plate 95 is slidably provided outside the guide frame 33 along with the slide plate 9. The cover plate 95 can slide to block the second equalizing hole 337. When cleaning the filler, the slide plate 9 slides to separate from the second inlet 82, and at the same time drives the cover plate 95 to move to the second equalizing hole 337 to block the second equalizing hole 337, so that the water in the guide frame 33 only flows out through the first equalizing hole 311, thereby improving the cleaning effect of the filler.

When the driving member 4 motor drives the driving rod 333 to rotate, the eccentric protrusion 334 drives the pressing plate 96 to move toward the equalizing hole 1 311, and the water in the guide frame 33 is squeezed out through the equalizing hole 1 311, thereby increasing the speed of water entering the material frame 2 and improving the flushing effect of the filler.

[0057] Reference Figures 7 to 10 , the pressure plate 96 moves repeatedly to squeeze the water, and an annular groove 336 is provided on the driving rod 333 and connected to the thread groove 335. The push rod 91 is provided with an elastic member 3 911, which can be set as a spring, one end of which is connected to the push rod 91, and the other end is connected to the inner wall of the guide frame 33. The driving rod 333 rotates to drive the push rod 91 to move, and the movement of the push rod 91 drives the slide plate 9 to move. After the slide plate 9 is separated from the second inlet 82, the push rod 91 moves to the annular groove 336. Under the action of the annular groove 336, the push rod 91 stops moving when the driving rod 333 rotates, and the slide plate 9 is in a separated state from the second inlet 82. At this time, it is convenient for the driving rod 333 to continue to rotate to adjust the position of the pressure plate 96. When the position of the slide plate 9 needs to be adjusted, the driving rod 333 is rotated in the opposite direction, and the elastic member 3 911 pushes the push rod 91 to cooperate with the thread groove 335, so that the push rod 91 returns to the initial position, thereby facilitating the slide plate 9 to move to the initial position.

[0058] The implementation principle of the present invention is: when the filler needs to be cleaned, the power part 41 drives the material frame 2 to rotate, and the stop block 72 cooperates with the stop rod 71 to drive the partition 5 to rotate relative to the middle rod 6, so as to expand the corresponding filling cavity and increase the gap between the materials in the expanded filling cavity. At this time, the position of the slide plate 9 is adjusted to make the water in the collection frame 32 flow out through the second inlet 82, and the water flowing out of the second inlet 82 is concentrated into the expanded filling cavity to flush the material. At the same time, as the gap between the materials increases, the impurities between the materials can be removed, the cleaning cycle of the filler is shortened, and the exhaust gas treatment efficiency is improved.

[0059] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
