Description

Technical Field

[0001] This invention relates to the field of waste gas filtration equipment technology, specifically to a VOCs adsorption device for industrial waste gas. Background Technology

[0002] Industrial waste gas refers to the gaseous substances emitted by industrial enterprises during production activities such as production, processing, combustion, and chemical reactions. These substances do not participate in the final product formation and contain various pollutants. As an important component of industrial pollution sources, its generation is directly related to industry type, production process, and raw material characteristics. VOCs waste gas, on the other hand, is a gaseous mixture emitted from industrial production and related activities, with volatile organic compounds as the core pollutants. It belongs to the main type of industrial organic waste gas. VOCs adsorption technology relies on the porous structure or surface chemical forces of the adsorbent to capture and enrich VOCs molecules in the waste gas. It is a recovery-type treatment technology for achieving waste gas purification and VOCs recovery, and it is also one of the core processes for treating low-to-medium concentration VOCs waste gas. It is widely used in end-of-pipe treatment in industries such as coating, printing, and petrochemicals. The core logic of this technology lies in using the interaction between the adsorbent and VOCs molecules to promote the transfer of VOCs from the gas phase to the solid phase of the adsorbent, thereby achieving the goal of gas-solid separation.

[0003] Most existing VOCs adsorption devices employ a static installation design for the adsorption bed. During actual operation, uneven airflow distribution of waste gas within the bed creates adsorption dead zones, preventing some adsorbent from fully contacting the VOCs waste gas. This directly reduces the effective utilization rate of the adsorbent and the overall purification efficiency of the device. Furthermore, the granular adsorbent packed in the adsorption bed gradually forms a bridging structure under the compaction and inter-particle compression during long-term operation, leading to localized pore blockage in the bed. This not only increases the resistance to waste gas flow but also further disrupts the uniformity of airflow distribution, ultimately shortening the stable operating cycle of the adsorption bed and increasing the equipment's maintenance costs. Summary of the Invention

[0004] The purpose of this invention is to address the problem that most existing VOCs adsorption devices employ a static installation design for the adsorption bed. During actual operation, uneven airflow distribution within the bed creates adsorption dead zones, preventing some adsorbent from fully contacting the VOCs, directly reducing the effective utilization rate of the adsorbent and the overall purification efficiency of the device. Furthermore, the granular adsorbent packed in the adsorption bed gradually forms bridging structures under the compaction and long-term inter-particle compression, leading to localized pore blockage in the bed. This not only increases the resistance to gas flow but also further disrupts the uniformity of airflow distribution, ultimately shortening the stable operating cycle of the adsorption bed and increasing the equipment's maintenance costs. The invention provides a VOCs adsorption device for industrial waste gas.

[0005] To achieve the above object, the present invention provides the following technical solution: a VOCs adsorption device in industrial waste gas, comprising: an adsorption barrel, an air inlet pipe is penetrated and arranged at the bottom end of the adsorption barrel, an exhaust pipe is penetrated and arranged at the top end of the adsorption barrel, and the air inlet pipe and the exhaust pipe are symmetrically distributed. An adsorbent is arranged inside the adsorption barrel, and a vibrating member for driving the main body of the adsorbent to shake up and down is arranged inside the adsorption barrel, and the vibrating member is arranged below the adsorbent. An activation member for accumulating the gas entering the adsorption barrel from the air inlet pipe and driving the vibrating member to rotate through gas pressure is arranged inside the adsorption barrel, and the activation member is arranged below the vibrating member; The vibrating member includes an annular rotating groove opened on the inner wall of the adsorption barrel. A cross-shaped mounting frame is rotatably connected in the rotating groove. A top block is fixedly connected to the top end of the mounting frame, and one side of the top block abuts against the inner wall of the adsorption barrel. When the activation member drives the mounting frame to rotate along the rotating groove, the top block at the top end of the mounting frame intermittently jacks up the main body of the adsorbent.

[0006] As a further scheme of the present invention: four groups of the top blocks are provided and symmetrically distributed at the top end of the cross-shaped mounting frame.

[0007] As a further scheme of the present invention: a plug post is fixedly connected to the bottom end of the mounting frame, and a guiding block is spirally wound on the outer circular surface of the plug post.

[0008] As a further scheme of the present invention: the adsorbent includes a moving groove in the shape of "|" opened on the inner wall of the adsorption barrel. An impact block is slidably inserted in the moving groove. A spring is fixedly connected to the bottom end of the impact block, and the bottom end of the spring is fixedly connected to the inner bottom end of the moving groove. An adsorption bed is fixedly connected to the inner side of the impact block.

[0009] As a further scheme of the present invention: the adsorption bed is composed of an outer frame and granular adsorption materials filled in the outer frame. The outer side of the outer frame of the adsorption bed abuts against the inner wall of the adsorption barrel, and the inner side of the impact block is fixedly connected to the outer frame of the adsorption bed.

[0010] As a further scheme of the present invention: a push block is fixedly connected to the bottom end of the outer frame of the adsorption bed. The push block is hemispherical. Multiple groups of the push blocks are provided and evenly distributed at the bottom end of the outer frame of the adsorption bed. The top block is located below the outer frame of the adsorption bed. When the mounting frame drives the top block to rotate, the top block abuts against the arc surface of the hemispherical push block, pushing the adsorption bed to move upward and stretching the spring until the impact block impacts the inner top end of the moving groove and transmits the impact force to the adsorption bed. When the top block is misaligned with the push block, the spring returns to its original length, driving the impact block and the adsorption bed to move downward and reset.

[0011] As a further embodiment of the present invention: the activator includes a gas collecting pipe fixedly connected to the bottom of the adsorption barrel and communicating with the air inlet pipe. A gas storage cylinder is slidably inserted into the top of the air inlet pipe. A rotating cylinder is fixedly connected to the top of the top gas storage cylinder. An insertion hole is opened at the top of the rotating cylinder. A spiral guide groove is opened on the inner wall of the insertion hole. The spiral guide groove on the inner wall of the insertion hole is adapted to the guide block spirally wound on the outer circular surface of the insertion post. The insertion hole is located directly below the insertion post. A limiting groove is opened on the inner wall of the adsorption barrel, which only allows the gas storage cylinder to move up and down but does not allow the gas storage cylinder to rotate. A limiting rod is fixedly connected to the outer side of the gas storage cylinder. The limiting rod is slidably inserted into the limiting groove.

[0012] As a further aspect of the present invention: the outer circular surface of the gas collecting pipe is provided with an exhaust groove one, and the outer circular surface of the gas storage cylinder is provided with an exhaust groove two. In the initial state, the top of the gas collecting pipe abuts against the top of the inside of the gas storage cylinder. At this time, exhaust groove one and exhaust groove two are misaligned, and the gas collecting pipe and the inside of the gas storage cylinder form a sealed space. As gas continues to enter, the air pressure in the sealed space inside the gas collecting pipe and the gas storage cylinder increases, pushing the gas storage cylinder upward, so that the insert is inserted into the insertion hole. When the insert is fully inserted into the insertion hole, exhaust groove one and exhaust groove two are completely aligned, and the gas inside the gas collecting pipe and the gas storage cylinder is quickly discharged through the exhaust grooves. The air pressure in the inner part of the gas collecting pipe and the gas storage cylinder decreases, and the gas storage cylinder resets under the action of gravity. During this process, when exhaust groove one and exhaust groove two are not completely aligned, the air intake of the sealed space inside the gas collecting pipe and the gas storage cylinder is greater than the air exhaust, causing the air pressure inside the gas to continue to rise.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the adsorption element enables the adsorption bed to slide up and down and vibrate due to impact, which effectively avoids the formation of airflow dead zones in the adsorption bed, prevents the granular adsorption material from forming a bridging structure due to compression, ensures full contact between the adsorption material and VOCs waste gas, improves the effective utilization rate of the adsorbent and the purification efficiency of the device, and at the same time, the outer frame of the adsorption bed abuts against the inner wall of the adsorption tank to avoid short circuit of waste gas, further ensuring the purification effect. 2. In this invention, the device can be driven by the air pressure of the exhaust gas itself through the activation element, without the need for additional power components such as motors, which significantly reduces the energy consumption and maintenance costs of the device. At the same time, the air pressure drive method has good stability and continuity, and can automatically adjust the operating frequency according to the exhaust gas intake volume, adapting to the exhaust gas treatment needs under different working conditions and improving the applicability of the device. 3. In this invention, the linear motion of the gas storage cylinder can be converted into the rotational motion of the mounting frame by the vibrating component, so as to realize the uniform intermittent pushing of the top block on the adsorption bed, ensuring the regularity and uniformity of the adsorption bed vibration, avoiding excessive local vibration intensity that could lead to pulverization of the adsorption material, and extending the service life of the adsorption material. At the same time, the rotating pushing method can cover the entire bottom of the adsorption bed, ensuring that the vibration effect is consistent throughout the adsorption bed and optimizing the overall adsorption efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0018] Reference Figure 1 In this embodiment of the invention, the VOCs adsorption device in industrial waste gas includes: an adsorption tank 1, an inlet pipe 2 extending through the bottom of the adsorption tank 1, an exhaust pipe 3 extending through the top of the adsorption tank 1, and the inlet pipe 2 and the exhaust pipe 3 being symmetrically distributed; an adsorption element 4 being disposed inside the adsorption tank 1; a vibrating element 6 being disposed inside the adsorption tank 1 to push the main body of the adsorption element 4 to shake up and down, and the vibrating element 6 being disposed below the adsorption element 4; and an activating element 5 being disposed inside the adsorption tank 1 to accumulate the gas entering the adsorption tank 1 from the inlet pipe 2 and to drive the vibrating element 6 to rotate by the gas pressure, the activating element 5 being disposed below the vibrating element 6.

[0019] Reference Figures 2 to 3The adsorption component 4 includes a U-shaped movable groove 41 formed on the inner wall of the adsorption tank 1. An impact block 42 is slidably inserted into the movable groove 41. A spring 43 is fixedly connected to the bottom end of the impact block 42. The bottom end of the spring 43 is fixedly connected to the bottom end of the movable groove 41. An adsorption bed 44 is fixedly connected to the inner side of the impact block 42. The adsorption bed 44 consists of an outer frame and granular adsorption material filled inside the outer frame. The outer side of the outer frame of the adsorption bed 44 abuts against the inner wall of the adsorption tank 1. The inner side of the impact block 42 is fixedly connected to the outer frame of the adsorption bed 44. A push block 45 is fixedly connected to the bottom end of the outer frame of the adsorption bed 44. The push block 45 is hemispherical, and multiple sets of push blocks 45 are evenly distributed at the bottom of the outer frame of the adsorption bed 44. The top block 63 is located below the outer frame of the adsorption bed 44. When the mounting frame 62 drives the top block 63 to rotate, the top block 63 abuts against the arc surface of the hemispherical push block 45, pushing the adsorption bed 44 to move upward and causing the spring 43 to extend until the impact block 42 collides with the top of the moving groove 41 and transmits the impact force to the adsorption bed 44. When the top block 63 and the push block 45 are misaligned, the spring 43 returns to its original length, causing the impact block 42 and the adsorption bed 44 to move downward and reset.

[0020] The above scheme is adopted: through the coordinated operation of the moving groove 41, the impact block 42, the spring 43, the adsorption bed 44 and the push block 45, the adsorption bed 44 is moved up and down intermittently and vibrated by impact, breaking the dead zone of airflow in the adsorption bed 44, avoiding the formation of bridging structure by particulate adsorption material, and at the same time enhancing the contact efficiency between adsorption material and VOCs waste gas, improving the effective utilization rate of adsorption bed 44 and the overall purification effect of the device.

[0021] Reference Figures 4 to 6The activator 5 includes a gas collecting pipe 51 fixedly connected to the bottom of the adsorption tank 1 and connected to the air inlet pipe 2. A gas storage cylinder 52 is slidably inserted into the top of the air inlet pipe 2. A rotating cylinder 55 is fixedly connected to the top of the top gas storage cylinder 52. An insertion hole 56 is opened at the top of the rotating cylinder 55. A spiral guide groove is opened on the inner wall of the insertion hole 56, and the spiral guide groove on the inner wall of the insertion hole 56 is adapted to the guide block spirally wound on the outer circular surface of the insertion post 64. The insertion hole 56 is located directly below the insertion post 64. A limiting groove 53 is opened on the inner wall of the adsorption tank 1, which only allows the gas storage cylinder 52 to move up and down but does not allow the gas storage cylinder 52 to rotate. A limiting rod 54 is fixedly connected to the outer side of the gas storage cylinder 52. The limiting rod 54 is slidably inserted into the limiting groove 53. An exhaust groove 1 57 is opened through the outer circular surface of the gas collecting pipe 51, and an exhaust groove 2 58 is opened through the outer circular surface of the gas storage cylinder 52. In the initial state... The top of the gas collecting pipe 51 abuts against the top of the inside of the gas storage cylinder 52. At this time, the first exhaust groove 57 and the second exhaust groove 58 are misaligned, and a sealed space is formed inside the gas collecting pipe 51 and the gas storage cylinder 52. As gas continues to enter, the air pressure in the sealed space inside the gas collecting pipe 51 and the gas storage cylinder 52 increases, pushing the gas storage cylinder 52 upward, so that the insert 64 is inserted into the insertion hole 56. When the insert 64 is fully inserted into the insertion hole 56, the first exhaust groove 57 and the second exhaust groove 58 are completely aligned, and the gas inside the gas collecting pipe 51 and the gas storage cylinder 52 is quickly discharged through the exhaust groove. The air pressure in the inner part of the gas collecting pipe 51 and the gas storage cylinder 52 decreases, and the gas storage cylinder 52 returns to its original position under the action of gravity. During this process, when the first exhaust groove 57 and the second exhaust groove 58 are not completely aligned, the air intake of the sealed space inside the gas collecting pipe 51 and the gas storage cylinder 52 is greater than the exhaust volume, causing the air pressure inside the gas to continue to rise.

[0022] The above solution utilizes the linkage design of the gas collection pipe 51, gas storage cylinder 52, limiting groove 53, limiting rod 54, rotating cylinder 55, insertion hole 56, exhaust groove one 57 and exhaust groove two 58 to drive the gas storage cylinder 52 to rise and fall by means of the pressure change of the industrial waste gas itself. This eliminates the need for additional power equipment such as motors, reducing the energy consumption and maintenance costs of the device. At the same time, it enables the periodic automatic drive of the vibrating component 6, improving the stability and continuity of the device's operation.

[0023] Reference Figures 7 to 8 The vibrating element 6 includes an annular rotating groove 61 formed on the inner wall of the adsorption barrel 1. A cross-shaped mounting frame 62 is rotatably connected in the rotating groove 61. A top block 63 is fixedly connected to the top of the mounting frame 62, and one side of the top block 63 abuts against the inner wall of the adsorption barrel 1. When the activating element 5 drives the mounting frame 62 to rotate along the rotating groove 61, the top block 63 at the top of the mounting frame 62 intermittently lifts the main body of the adsorption element 4. There are four sets of top blocks 63, symmetrically distributed at the top of the cross-shaped mounting frame 62. A post 64 is fixedly connected to the bottom of the mounting frame 62, and a guide block is spirally wound on the outer surface of the post 64.

[0024] The above scheme is adopted: through the structural design of the annular rotating groove 61, the cross-shaped mounting frame 62, the four sets of top blocks 63 and the insertion post 64, and by utilizing the cooperation between the insertion post 64 and the spiral guide groove in the insertion hole 56, the linear lifting motion of the gas storage cylinder 52 is converted into the rotational motion of the mounting frame 62, so as to realize the uniform intermittent pushing of the top block 63 on the adsorption bed 44, ensuring the regularity and stability of the vibration of the adsorption bed 44, and further optimizing the utilization efficiency of the adsorption material.

[0025] The working principle of this invention is as follows: Industrial waste gas enters the bottom of the adsorption tank 1 through the inlet pipe 2 and first flows into the gas collecting pipe 51 connected to the inlet pipe 2. In the initial state, the exhaust groove 57 of the gas collecting pipe 51 and the exhaust groove 58 of the gas storage cylinder 52 are misaligned, forming a sealed space inside the gas collecting pipe 51 and the gas storage cylinder 52. As waste gas is continuously injected, the air pressure in the sealed space gradually increases. When the air pressure reaches a preset threshold, the air pressure pushes the gas storage cylinder 52 to slide upward along the limiting groove 53. The limiting rod 54 moves synchronously along the limiting groove 53, ensuring that the gas storage cylinder 52 only performs linear lifting and lowering motion without rotation. During the upward movement of the gas storage cylinder 52, the rotating cylinder 55 at the top moves upward synchronously until the rotating cylinder 55... The insertion hole 56 at the top of the 5-piece vibrating element 6 is inserted into the insertion post 64. The guide block on the outer circular surface of the insertion post 64 is embedded in the spiral guide groove on the inner wall of the insertion hole 56. As the air storage cylinder 52 continues to rise, the spiral guide groove generates a lateral thrust on the guide block, causing the insertion post 64 and the cross-shaped mounting bracket 62 at the top to rotate along the annular rotating groove 61. During the rotation of the mounting bracket 62, the four sets of top blocks 63 at its top move in a circular motion simultaneously. When the top block 63 rotates to directly below the push block 45 at the bottom of the adsorption bed 44, the top block 63 contacts the arc surface of the hemispherical push block 45 and pushes upward, pushing the adsorption bed 44 and the inner impact block 42 to slide upward along the moving groove 41. During this process, the spring 43 extends until the impact block 45... 2. The impact block 63 collides with the top of the moving groove 41. The impact force is transmitted to the adsorption bed 44, causing the granular adsorption material in the adsorption bed 44 to vibrate. When the top block 63 rotates with the mounting frame 62 and is misaligned with the push block 45, the pushing force of the top block 63 on the push block 45 disappears, the spring 43 returns to its original length, and drives the impact block 42 and the adsorption bed 44 to move downward and reset, completing one vibration cycle. When the insertion post 64 is fully inserted into the insertion hole 56, the exhaust groove 57 of the gas collecting pipe 51 and the exhaust groove 58 of the gas storage cylinder 52 are fully aligned. The waste gas in the sealed space is quickly discharged through the exhaust groove to the middle of the adsorption tank 1. At this time, the air pressure in the sealed space drops sharply, and the gas storage cylinder 52 moves along the limiting groove 53 under its own gravity. As the device slides down to reset, the insertion hole 56 and the insertion post 64 gradually disengage, the rotational power of the mounting bracket 62 disappears, and as the exhaust gas is continuously injected into the gas collection pipe 51 again, the air pressure in the sealed space rises again. The above actions of raising and lowering the gas storage cylinder 52, rotating the mounting bracket 62, and pushing the adsorption bed 44 by the top block 63 are repeated to achieve continuous and regular vibration of the adsorption bed 44. After the exhaust gas is discharged from the exhaust trough, it flows upward and passes through the adsorption bed 44 which is in a state of continuous vibration. The granular adsorption material in the adsorption bed 44 breaks the dead zone of the airflow due to the vibration and does not form a bridging structure. It fully contacts the exhaust gas and efficiently captures VOCs molecules in the exhaust gas. The purified gas flows upward and finally meets the emission standards through the exhaust pipe 3 at the top.The adsorption element 4 enables the adsorption bed 44 to slide up and down and vibrate due to impact, effectively avoiding airflow dead zones within the adsorption bed 44 and preventing the granular adsorption material from forming bridging structures due to compression. This ensures full contact between the adsorption material and VOCs waste gas, improving the effective utilization rate of the adsorbent and the purification efficiency of the device. Simultaneously, the outer frame of the adsorption bed 44 abuts against the inner wall of the adsorption tank 1, preventing waste gas short-circuiting and further guaranteeing the purification effect. The activator 5 allows the device to operate using the waste gas's own pneumatic pressure, eliminating the need for additional motors or other power components, significantly reducing the device's energy consumption and maintenance costs. Furthermore, the pneumatic drive method offers good performance... The stability and continuity of the device allow for automatic adjustment of the operating frequency based on the amount of waste gas entering the system, adapting to different waste gas treatment needs under various operating conditions and improving the applicability of the device. The vibrating element 6 converts the linear motion of the gas storage cylinder 52 into the rotational motion of the mounting frame 62, enabling the top block 63 to uniformly and intermittently push the adsorption bed 44. This ensures the regularity and uniformity of the vibration of the adsorption bed 44, preventing excessive local vibration intensity from causing pulverization of the adsorption material and extending its service life. Simultaneously, the rotating pushing method covers the entire bottom of the adsorption bed 44, ensuring consistent vibration throughout the adsorption bed 44 and optimizing the overall adsorption efficiency.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
