Description

Technical Field

[0001] This invention relates to the field of environmental protection equipment technology, specifically to an activated carbon adsorption device for environmental protection. Background Technology

[0002] Activated carbon adsorption is a process that utilizes the physical and chemical properties of activated carbon to adsorb and fix impurities (such as organic matter, inorganic matter, odor molecules, etc.) in the pores of a gas. This method can be used to adsorb and treat harmful gases, thereby achieving the goal of protecting the environment.

[0003] To optimize airflow distribution and improve activated carbon utilization, the industry has implemented numerous improvements. A common approach is to use a multi-layered, segmented activated carbon filling structure, combined with baffles or airflow distributors, attempting to guide exhaust gas more evenly through the adsorption layer. While this method can effectively achieve conventional filtration results, when treating complex industrial exhaust gases (such as those containing oil mist, sticky particles, or easily condensable components), these adhesive substances can clog the pores of the activated carbon itself and are more likely to gradually adhere to and accumulate on the surfaces of key mechanical components in the airflow distribution system (such as baffle shafts and support mesh). This contamination alters the local aerodynamic shape, increases the frictional resistance of moving parts, and in severe cases, can seriously degrade or even completely "freeze" the sensitivity and accuracy of the airflow regulation mechanism, causing the activated carbon filter to fail during long-term operation.

[0004] Therefore, since it does not meet the existing needs, we propose an activated carbon adsorption device for environmental protection. Summary of the Invention

[0005] This invention provides an activated carbon adsorption device for environmental protection. By converting and storing the deflection motion of an adaptive guide plate into mechanical energy via a unidirectional transmission mechanism, the cleaning action can respond to the actual degree of filter clogging, achieving on-demand, energy-saving intelligent maintenance. The compound motion of the cleaning rollers effectively removes deposits from the support mesh, ensuring unobstructed airflow. The rapid reset mechanism driven by the energy-storing coil spring not only automatically returns the mechanism to its original position, but the inertial vibration generated further effectively removes pollutants. This system requires no external power or manual intervention throughout the entire process, significantly improving the long-term operational stability and maintenance-free nature of the adaptive airflow distribution system, and solving the problems mentioned in the background section.

[0006] The present invention provides the following technical solution: an activated carbon adsorption device for environmental protection, comprising an adsorption body, wherein a gas storage chamber is provided inside the adsorption body, and a sealing plate is installed on the side of the gas storage chamber near the gas inlet. The side of the sealing plate facing the gas inlet is an open side, and the side facing away from the gas inlet is a closed structure. Furthermore, a plurality of connecting holes are provided on the top and bottom surfaces of the sealing plate. The top and bottom outer surfaces of the sealing plate are slidably provided with moving parts corresponding to the positions of the connecting holes. The moving parts are used to carry the activated carbon filter element. An energy storage trigger self-cleaning component is integrated inside the moving parts. The energy storage trigger self-cleaning component includes a cleaning roller. The cleaning roller is slidably disposed inside the limiting groove at the beginning of the inner wall of the moving parts. The cleaning roller is connected to the transmission mechanism disposed in the second cavity inside the moving parts through a rotating connecting rod.

[0008] As an optional embodiment of the activated carbon adsorption device for environmental protection described in this invention, the connecting shaft passes through the side wall of the moving part and is rotatably installed in the second cavity, and a sector gear is fixedly installed on the part of the connecting shaft located in the second cavity.

[0009] As an optional embodiment of the activated carbon adsorption device for environmental protection described in this invention, an energy storage rod is provided in parallel within the second cavity. A bevel gear is provided on the energy storage rod corresponding to each sector gear and connected to it via a one-way clutch. Each bevel gear meshes with the corresponding sector gear.

[0010] As an alternative embodiment of the activated carbon adsorption device for environmental protection described in this invention, a rotating lead screw is further provided in the second cavity, and the energy storage rod is connected to the rotating lead screw via a transmission belt.

[0011] As an optional embodiment of the activated carbon adsorption device for environmental protection described in this invention, one end of the rotating connecting rod of the cleaning roller extends into the second cavity and is connected to the rotating lead screw through a connector. The upper part of the connector forms a threaded pair with the rotating lead screw, and its lower part is slidably sleeved with the rotating connecting rod.

[0016] The present invention has the following beneficial effects: 1. This activated carbon adsorption device for environmental protection, through the forced flow guidance of the sealing plate and the single outlet design of the connecting hole, creates an unavoidable path for the exhaust gas to penetrate the activated carbon layer, thus solving the problems of airflow short-circuiting and adsorption dead zones to a certain extent. Combined with the adaptive adjustment mechanism composed of the arc-shaped guide plate and torsion spring, the system can dynamically balance the main and bypass airflows according to the saturation of the filter element, forcing the exhaust gas to deeply utilize the deep adsorption capacity of the activated carbon, thereby improving the overall utilization rate and extending the effective filtration cycle. At the same time, the activated carbon component is integrated into the sliding moving part, making filter element replacement convenient and significantly reducing maintenance costs and time. As a result, the entire system achieves a unity of high-efficiency purification, intelligent self-adaptation, and ease of operation.

[0017] 2. This activated carbon adsorption device for environmental protection converts the deflection motion of the adaptive guide plate into mechanical energy via a unidirectional transmission mechanism and stores it. This allows the cleaning action to respond to the actual degree of clogging of the filter element, achieving on-demand, energy-saving intelligent maintenance. The compound motion of the cleaning rollers effectively removes deposits from the support mesh surface, ensuring unobstructed airflow. The rapid reset mechanism driven by the energy-storing coil spring not only automatically returns the mechanism to its original position, but the inertial vibration generated further effectively removes pollutants. The entire system requires no external power or manual intervention, significantly improving the long-term operational stability and maintenance-free nature of the adaptive airflow distribution system.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1, please refer to Figures 1-10 To effectively improve the adsorption efficiency of activated carbon and solve the technical problems of "airflow short circuit" or "uneven diffusion" in traditional adsorption devices, this solution improves the internal structure of the adsorption unit 1. Specifically, a gas storage chamber 101 is provided inside the adsorption unit 1. A specially designed sealing plate 102 is installed on the side of the gas storage chamber 101 near the air inlet. The side of the sealing plate 102 facing the air inlet is completely open and directly connected to the air inlet of the adsorption unit 1, while the other side facing away from the air inlet is a completely sealed structure. The core purpose of this asymmetrical design is to forcefully guide and rectify the initial airflow: when the waste gas enters the gas storage chamber 101 from the air inlet, it will first be collected and confined in the rectification chamber formed by the open side of the sealing plate 102, thereby effectively preventing the waste gas from spreading and bypassing randomly throughout the chamber without organization, avoiding the problem of insufficient contact with the activated carbon in the future, and laying the structural foundation for high-efficiency filtration.

[0022] To guide the collected airflow through the activated carbon layer in an orderly manner, this design provides several connecting holes 103 on the top and bottom surfaces of the sealing plate 102. More importantly, on the outer surfaces of the top and bottom of the sealing plate 102, corresponding to the positions of these connecting holes 103, there are sliding moving parts 2 specifically designed to support the activated carbon filter element. This creates an unavoidable purification path: the only outlet for the waste gas collected in the rectifier chamber is the connecting holes 103 on the top and bottom of the sealing plate 102. When the waste gas passes through these channels, it is forcibly adsorbed and purified by the activated carbon components tightly attached to the outside of the channels. The purified gas then enters the rear space of the gas storage chamber 101 and finally flows evenly to the exhaust port for discharge.

[0023] To further optimize airflow distribution and adaptively improve the overall utilization efficiency of activated carbon, this solution adds a rotatable arc-shaped guide plate 201 to the outer area of ​​each connecting hole 103 of the sealing plate 102. This arc-shaped guide plate 201 is hinged to the inner wall of the moving part 2 via a connecting shaft 212 and is initially reset by a connecting torsion spring 202. This allows it to maintain a large tilt angle when the activated carbon filter element is clean, thus forming an auxiliary airflow channel between itself and the filter element surface. Its core mechanism lies in utilizing the system's own fluid feedback for adjustment: when the activated carbon filter element is clean and has low resistance, most of the exhaust gas smoothly penetrates the filter element, resulting in lower airflow pressure acting on the arc-shaped guide plate 201. The auxiliary channel remains unobstructed. As the activated carbon filter element gradually becomes saturated due to continuous adsorption, its pore resistance increases, causing more exhaust gas to tend to pass through the auxiliary channel with lower resistance (i.e., the gap between the arc-shaped guide plate 201 and the filter element). The dynamic pressure generated by this increased bypass airflow also increases. When this force is sufficient to overcome the torque of the connecting torsion spring 202, it will push the arc-shaped guide plate 201 to rotate, reducing its inclination angle and thus automatically narrowing the cross-sectional area of ​​the auxiliary channel. This dynamic adjustment process forces some of the airflow that originally attempted to bypass to continue penetrating the deep structure of the activated carbon filter element, achieving adaptive rebalancing of the airflow path throughout the entire service life of the filter element, and significantly improving the overall utilization rate of the activated carbon adsorption capacity.

[0024] The advantages of this design are multifaceted. First, the physical structure of the sealing plate 102 and the connecting hole 103 forcibly defines the core flow trajectory of the exhaust gas, ensuring that all exhaust gas must penetrate the activated carbon layer, thus avoiding adsorption dead zones and airflow short circuits to a certain extent. Second, the combination of the arc-shaped guide plate 201 and the connecting torsion spring 202 gives the device the ability to self-adjust according to the real-time status of the filter element, optimizing airflow distribution and extending the effective filtration cycle. Finally, integrating the activated carbon assembly onto the sliding movable part 2 makes the installation, replacement, or maintenance of the filter element more convenient, eliminating the need for complex disassembly of the machine. While ensuring high-efficiency filtration performance, it also greatly reduces the cost and time of operation and maintenance, making the entire system highly efficient, adaptable, and easy to operate.

[0025] Example 2 addresses the problem of long-term adhesion of oil mist, sticky particles, or condensate in exhaust gas, leading to contamination of critical components of the airflow distribution system and consequently affecting its adjustment sensitivity and accuracy. This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1-10 This solution integrates an energy-storing trigger-type self-cleaning component inside the moving part 2. This component includes a cleaning roller 203, which is slidably set in a limiting groove 211 symmetrically opened on the inner wall of the moving part 2 via a rotating connecting rod 204. The flexible needles arranged in a circumferential array on the outer surface of the cleaning roller 203 are designed in terms of length and hardness to ensure that it can effectively disturb and scrape the bottom support mesh of the filter element during operation, peeling off loose particulate pollutants that were attached early, while not piercing or damaging the structure of the activated carbon filter element body, thereby maintaining the original design air permeability of this key interface.

[0026] Because the connecting shaft 212 at one end of the arc-shaped guide plate 201 penetrates the side wall of the moving part 2 and is rotatably installed in the second cavity 216 inside it, and a sector gear 213 is fixedly installed on the part of the connecting shaft 212 located inside the second cavity 216, and a storage rod 208 is provided parallel to it inside the second cavity 216, on which a bevel gear 214 is provided corresponding to each sector gear 213 and connected to it through a one-way clutch, and each bevel gear 214 meshes with the corresponding sector gear 213, such as The advantage of this setup is that when the activated carbon filter element in a certain area experiences a slight change in local airflow resistance due to the adsorption of impurities, the reciprocating deflection motion of the arc-shaped guide plate 201 in seeking a new balance can be converted into the unidirectional intermittent rotation of the bevel gear 214 through the sector gear 213. Due to the presence of the unidirectional clutch, the angle change of the arc-shaped guide plate 201 can be converted into an incremental force that drives the energy storage rod 208 to rotate in the same direction, thereby collecting and storing the dispersed angle changes of the arc-shaped guide plate 201 as continuous mechanical rotational energy.

[0027] To further convert the accumulated rotational energy into cleaning action, an energy storage rod 208 is connected to a rotating lead screw 209 via a transmission belt 207 inside the second cavity 216. This arrangement allows the slow rotation of the energy storage rod 208 to synchronously drive the rotating lead screw 209 to rotate. One end of the rotating connecting rod 204 of the cleaning roller 203 extends into the second cavity 216 and is connected to the rotating lead screw 209 via a connector 210. The upper part of the connector 210 forms a threaded pair with the rotating lead screw 209, while the lower part is slidably sleeved with the rotating connecting rod 204. Therefore, the rotation of the rotating lead screw 209 is converted into the smooth linear movement of the connector 210 and the connected rotating connecting rod 204 along the limiting groove 211.

[0028] Since a first cavity 215 is also provided inside the limiting slide groove 211, in which a connecting gear 205 and a fixed connecting rack 206 are arranged, the connecting gear 205 is fixedly sleeved on the rotating connecting rod 204. When the rotating connecting rod 204 moves linearly, the connecting gear 205 rolls along the connecting rack 206, thereby forcing the rotating connecting rod 204 to drive the cleaning roller 203 to rotate at the same time. In this way, the cleaning roller 203 superimposes rotational motion in linear movement, and can perform a comprehensive scraping and cleaning of the bottom support surface of the filter element with a gradual and gentle compound action, effectively preventing local accumulation of pollutants.

[0029] Meanwhile, an energy storage coil spring (not shown in the figure) is also connected to the energy storage rod 208. The energy storage coil spring is used to store the mechanical energy generated by the drive of the bevel gear 214. A normally closed one-way rotary electronically controlled clutch is provided between the energy storage rod 208 and the energy storage coil spring. This setting ensures that the energy storage rod 208 can only rotate in one direction to tighten the coil spring when accumulating energy, and cannot freely reverse. When the cleaning roller 203 moves to the end of its stroke under the drive of the screw, it will trigger the preset position sensor. The sensor immediately sends a signal to the normally closed one-way rotary electronically controlled clutch, causing it to instantly release the lock between the energy storage rod 208 and the energy storage coil spring. At this time, the energy stored in the highly tensioned energy storage coil spring is suddenly released, driving the energy storage rod 208 to rotate high. The cleaning roller 203 rotates rapidly in the opposite direction and drives the rotating screw 209 to reverse through the transmission belt 207, thereby pulling the cleaning roller 203 to quickly reset along the limiting slide groove 211. This rapid reset motion has a dual positive effect: firstly, it enables the entire cleaning mechanism to quickly and accurately return to the initial standby position, preparing for the next cleaning cycle; secondly, the instantaneous high-speed motion and inertial vibration generated during the reset process help to completely shake off and dislodge loose contaminants that may have been scraped off during the cleaning process and temporarily stored on the flexible needle or component surface, allowing them to fall into the specially designed dust collection trough at the bottom of the equipment (not shown in the figure) by gravity, effectively preventing secondary adhesion of contaminants and significantly improving the final self-cleaning effect and the maintenance-free nature of the system.

[0030] It should be noted that normally closed one-way rotary electronically controlled clutches, position sensors, and one-way clutches are all technologies commonly used and existing in this field. Users can make adjustments according to their actual situation and their own needs, and will not be elaborated on here.

[0031] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0032] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
