Description

Technical Field

[0001] This invention relates to the field of gas filtration equipment technology, specifically a catalytic adsorption integrated decarbonization filter. Background Technology

[0002] The integrated catalytic adsorption decarbonization filter is a composite purification device that integrates physical adsorption and chemical catalysis. Through a dual-functional catalytic-adsorption material, it achieves efficient capture and in-situ conversion of carbon-based pollutants in gases or liquids, while simultaneously regenerating the adsorbent. VOCs filtration is one of the core application scenarios of this equipment, specifically targeting volatile organic compounds emitted in industrial production. It achieves integrated treatment of efficient capture, in-situ degradation, and material regeneration. In the specific treatment process, after VOCs gas enters the adsorption catalytic bed, carbon pollutants are captured by adsorption sites on the surface of the dual-functional material, allowing the purified gas to initially meet emission standards. When the adsorption catalytic bed approaches saturation, an auxiliary gas is introduced into the system. Under the action of the catalyst, VOCs undergo an oxidation reaction to produce carbon dioxide and water, releasing heat. The catalytic products are then discharged from the equipment, and the adsorption sites simultaneously regain activity. No additional desorption energy consumption is required throughout the entire process.

[0003] Existing integrated catalytic adsorption decarbonization filters can only support single-mode operation of adsorption filtration or desorption regeneration during use, and cannot achieve continuous treatment of VOCs waste gas. Faced with the continuous emission of VOCs waste gas in industrial production, the equipment needs to frequently switch operating modes. During the switching, the waste gas must be temporarily bypassed or directly shut down. This not only poses the environmental risk of direct discharge of waste gas exceeding the standard, but also seriously reduces the overall treatment efficiency of the equipment. At the same time, during the switching of operating modes, key parameters such as bed temperature and auxiliary gas flux need to be repeatedly adjusted. This not only increases the energy consumption of the system, but also increases the control complexity of the equipment, making it difficult for existing equipment to adapt to the routine treatment needs of low-concentration, high-volume VOCs waste gas. Summary of the Invention

[0004] The purpose of this invention is to address the problem that existing integrated catalytic adsorption decarbonization filters can only support single-mode operation of adsorption filtration or desorption regeneration during use, failing to achieve continuous treatment of VOCs waste gas. Faced with the continuous emission of VOCs waste gas during industrial production, the equipment needs to frequently switch operating modes, requiring temporary bypassing or direct shutdown of the waste gas during switching. This not only poses the environmental risk of excessive direct emissions but also severely reduces the overall treatment efficiency of the equipment. Furthermore, the switching process requires repeated adjustments to key parameters such as bed temperature and auxiliary gas flux, which increases the system's energy consumption and enhances the control complexity of the equipment. This makes it difficult for existing equipment to adapt to the routine treatment needs of low-concentration, high-volume VOCs waste gas. Therefore, this invention provides an integrated catalytic adsorption decarbonization filter.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated catalytic adsorption decarbonization filter, comprising: a mounting frame, wherein reaction chambers are fixedly connected to the mounting frame, wherein the reaction chambers are composed of a desorption chamber and an adsorption chamber, and the adjacent surfaces of the desorption chamber and the adsorption chamber are fixedly connected.

[0006] The reaction chamber is provided with a rectangular moving trough, and an adsorption catalyst bed is slidably connected in the moving trough. The moving trough allows the adsorption catalyst bed to freely enter and exit the desorption chamber and the adsorption chamber.

[0007] A positioning element is provided at the corner of the rectangular moving trough, and a switching element that pushes the adsorption catalytic bed to move is provided on the outside of the reaction chamber;

[0008] The switching component includes a straight-line push groove that penetrates the side of the reaction chamber. The push groove is located in the middle of the inner side of the moving groove and is situated between the desorption chamber and the adsorption chamber, communicating with the moving groove. An O-shaped mounting block is fixedly connected to the outside of the reaction chamber. A cavity is formed on the side of the mounting block that is in contact with the reaction chamber. A ball bearing assembly is slidably connected within the cavity. The ball bearing assembly consists of multiple sets of balls that abut against each other. A slot is formed on the side of the mounting block away from the reaction chamber, and the slot communicates with the cavity. The adsorption catalyst bed extends through the push groove and is fixedly connected to the ball bearing assembly. A push plate is fixedly connected to one end of the ball bearing assembly and extends through the slot. A linear actuator is fixedly connected to one side of the reaction chamber and is located inside the O-shaped mounting block. The push plate is fixedly connected to the movable end of the linear actuator.

[0009] As a further embodiment of the present invention: the moving trough penetrates the adjacent surfaces of the desorption chamber and the adsorption chamber, and the portions of the moving trough located in the desorption chamber and the adsorption chamber are symmetrically distributed in a C-shape. There are two sets of moving troughs, arranged vertically, and each set of moving troughs is slidably connected to an adsorption catalyst bed. One set of adsorption catalyst beds is located in the desorption chamber, and the other set of adsorption catalyst beds is located in the adsorption chamber.

[0010] As a further embodiment of the present invention: a drain pipe is connected to the bottom of the desorption chamber, an exhaust pipe is connected to the top of the desorption chamber, and an air inlet is connected to the side of the desorption chamber with a conical cross-section to increase the gas flow rate into the desorption chamber. The desorption chamber is uniformly and fixedly connected with multiple flow-generating fins in a straight line, and the fins are inclined. The bottom of the fins is located at half the position of the connection between the desorption chamber and the air inlet, so that after the gas enters the desorption chamber and comes into contact with the fins, a portion of the gas is intercepted by the fins and moves up along the inclined surface of the fins. The uninterrupted portion then comes into contact with the next set of fins, allowing the gas to diffuse rapidly in the desorption chamber and fully contact the adsorption catalyst bed.

[0011] As a further embodiment of the present invention: a VOCs inlet pipe is connected to the bottom of the adsorption chamber, and an exhaust pipe is connected to the top of the adsorption chamber. Multiple sets of flow fins are uniformly fixed in a fan shape inside the adsorption chamber. The multiple sets of fins are arranged directly above the inlet pipe. Through the multiple sets of fins distributed in a fan shape, the VOCs gas can diffuse rapidly in the adsorption chamber and fully contact the adsorption catalyst bed.

[0012] As a further embodiment of the present invention: the adsorption catalytic bed includes a rectangular outer frame disposed within a moving trough. The thickness and height of the outer frame are consistent with those of the moving trough. When the adsorption catalytic bed is fully inserted into the desorption chamber or adsorption chamber, the outer frame isolates the portion of the moving trough located at the connection point between the desorption chamber and the adsorption chamber. An adsorption material with a catalyst is fixedly connected inside the outer frame. A set of push blocks is symmetrically fixedly connected to the outer side of each set of outer frames. One end of the push block passes through the pushing groove and is fixedly connected to a set of ball bearings. One end of this set of ball bearings is fixedly connected to a push plate. A positioning hole is provided at the bottom corner of the outer frame, and the positioning hole is hemispherical.

[0013] As a further embodiment of the present invention: the positioning component includes a mounting hole at the bottom corner of the inner side of the moving groove, a positioning post is slidably inserted into the mounting hole, the top of the positioning post is hemispherical, and a spring is fixedly connected to the bottom of the positioning post. One end of the spring is fixedly connected to the bottom of the inner side of the mounting hole. In the initial state, the spring lifts the positioning post so that the hemispherical part at the top of the positioning post is higher than the mounting hole, and the size of the hemispherical part at the top of the positioning post is the same as that of the positioning hole.

[0014] As a further embodiment of the present invention: an O-shaped sealing groove is provided on the outside of the reaction chamber, the sealing groove is connected to the pushing groove, a sealing ring is rotatably connected in the sealing groove, and the sealing ring blocks and seals the pushing groove. The pushing block passes through the pushing groove and the sealing ring in sequence and is fixedly connected to the sealing ring, so that when the adsorption catalyst bed moves in the moving groove, the sealing ring moves synchronously in the sealing groove.

[0015] As a further embodiment of the present invention: four sets of the pushing grooves are provided, symmetrically distributed on both sides of the reaction chamber, and two sets of the sealing grooves are provided, with each set of sealing grooves communicating with the two sets of symmetrically distributed pushing grooves.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In this invention, the adsorption filtration and desorption regeneration are operated in parallel by alternating and synchronously switching two sets of adsorption catalytic beds in a moving tank. This eliminates the need for frequent switching of operating conditions and shutdown bypass, completely eliminating the environmental risk of direct discharge of waste gas exceeding standards, and significantly improving the overall treatment efficiency of the equipment. At the same time, it avoids the problems of increased energy consumption and increased control complexity caused by repeated adjustment of temperature and gas flow, and perfectly adapts to the routine treatment needs of low-concentration, high-volume VOCs waste gas.

[0018] 2. In this invention, the special arrangement design of the first and second diversion fins significantly increases the contact area and reaction time between the gas and the adsorption catalyst bed, enhancing the effect of pollutant capture, desorption and regeneration. Through the coordinated cooperation of the positioning and switching components, the positioning of the adsorption catalyst bed is ensured to be accurate and the switching is smooth, reducing the probability of equipment failure. The integrated design of the desorption chamber and the adsorption chamber reduces the overall footprint of the equipment and reduces the cost of on-site installation and subsequent maintenance.

[0028] 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.

[0029] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this invention, it should be noted that unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," and "set up" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. 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.

[0030] Reference Figures 1 to 2 In this embodiment of the invention, a catalytic adsorption integrated decarbonization filter includes: a mounting frame 7, on which reaction chambers are fixedly connected respectively, wherein the reaction chambers are composed of a desorption chamber 1 and an adsorption chamber 2, and the adjacent surfaces of the desorption chamber 1 and the adsorption chamber 2 are fixedly connected.

[0031] A rectangular moving trough 3 is provided inside the reaction chamber. An adsorption catalyst bed 4 is slidably connected inside the moving trough 3. The adsorption catalyst bed 4 can freely enter the desorption chamber 1 and the adsorption chamber 2 through the moving trough 3. The moving trough 3 penetrates the adjacent surfaces of the desorption chamber 1 and the adsorption chamber 2. The portions of the moving trough 3 located in the desorption chamber 1 and the adsorption chamber 2 are symmetrically distributed in a C-shape. There are two sets of moving trough 3, which are arranged vertically. Each set of moving trough 3 is slidably connected to a set of adsorption catalyst beds 4. One set of adsorption catalyst beds 4 is located in the desorption chamber 1, and the other set of adsorption catalyst beds 4 is located in the adsorption chamber 2.

[0032] A positioning element 5 is provided at the corner of the rectangular moving trough 3, and a switching element 6 is provided on the outside of the reaction chamber to move the adsorption catalytic bed 4.

[0033] Reference Figure 2 The bottom of the desorption chamber 1 is connected to a drain pipe 11, the top of the desorption chamber 1 is connected to an exhaust pipe 12, and the side of the desorption chamber 1 is connected to an air inlet hopper 13 with a conical cross-section, which increases the gas flow rate into the desorption chamber 1. The desorption chamber 1 is uniformly and fixedly connected to multiple flow-generating fins 14 in a straight line, and the fins 14 are in an inclined state. The bottom of the fins 14 is located at half of the connection between the desorption chamber 1 and the air inlet hopper 13, so that after the gas entering the desorption chamber 1 comes into contact with the fins 14, a portion of it is intercepted by the fins 14 and moves up along the inclined surface of the fins 14. The uninterrupted portion comes into contact with the next set of fins 14, so that the gas diffuses rapidly in the desorption chamber 1 and fully contacts the adsorption catalyst bed 4.

[0034] The above scheme is adopted: the conical cross-section design of the air inlet hopper 13 increases the gas flow rate entering the desorption chamber 1; the position setting of the inclined diversion fins 14 guides the gas to form a stepped diffusion path in the desorption chamber 1, increasing the contact area and contact time between the gas and the adsorption catalyst bed 4; and the precise layout of the drain pipe 11 and the exhaust pipe 12 enables the rapid separation and orderly discharge of desorption products, avoiding the accumulation of products in the desorption chamber 1 and affecting the reaction efficiency.

[0035] Reference Figure 2 The bottom of the adsorption chamber 2 is connected to a VOCs inlet pipe 21, and the top of the adsorption chamber 2 is connected to an exhaust pipe 22. Multiple sets of flow fins 23 are uniformly fixed in a fan shape inside the adsorption chamber 2. The multiple sets of fins 23 are located directly above the inlet pipe 21. Through the multiple sets of fins 23 distributed in a fan shape, the VOCs gas can diffuse rapidly in the adsorption chamber 2 and fully contact the adsorption catalyst bed 4.

[0036] The above scheme is adopted: the gas discharged from the VOCs inlet pipe 21 is diverted and guided by the fan-shaped diversion fins 23, eliminating the dead air zone in the adsorption chamber 2, so that the VOCs gas is evenly diffused to the surface of the adsorption catalyst bed 4, improving the capture efficiency of VOCs pollutants. The corresponding layout of the VOCs inlet pipe 21 and the exhaust pipe 22 ensures smooth gas flow and reduces the system operating resistance.

[0037] Reference Figure 4 The adsorption catalytic bed 4 includes a rectangular outer frame 41 disposed in the moving tank 3. The thickness and height of the outer frame 41 are the same as those of the moving tank 3. When the adsorption catalytic bed 4 is completely inserted into the desorption chamber 1 or the adsorption chamber 2, the outer frame 41 isolates the part of the moving tank 3 located at the connection between the desorption chamber 1 and the adsorption chamber 2. An adsorption material 42 with a catalyst is fixedly connected inside the outer frame 41. A set of push blocks 43 is symmetrically fixedly connected to the outside of each set of outer frames 41. One end of the push block 43 passes through the pushing groove 61 and is fixedly connected to a set of ball bearings. One end of this set of ball bearings is fixedly connected to the push plate 68. A positioning hole is provided at the bottom corner of the outer frame 41, and the positioning hole is hemispherical.

[0038] The above scheme is adopted as follows: by matching the size of the rectangular outer frame 41 with the moving groove 3, the desorption chamber 1 and the adsorption chamber 2 are separated after the adsorption catalytic bed 4 is moved into place, so as to avoid gas crossflow between the two chambers. The adsorption material 42 with catalyst is used to realize the integration of pollutant adsorption and catalytic degradation. The rigid connection between the push block 43 and the ball bearing assembly 66 ensures the uniformity of force during the movement of the adsorption catalytic bed 4. The structural design of the hemispherical positioning hole provides a structural basis for the precise positioning of the adsorption catalytic bed 4.

[0039] Reference Figures 2 to 3 The positioning component 5 includes a mounting hole 51 located at the bottom corner of the inner side of the moving groove 3. A positioning post 52 is slidably inserted into the mounting hole 51. The top of the positioning post 52 is hemispherical. A spring 53 is fixedly connected to the bottom of the positioning post 52. One end of the spring 53 is fixedly connected to the bottom of the inner side of the mounting hole 51. In the initial state, the spring 53 lifts the positioning post 52, so that the hemispherical part at the top of the positioning post 52 is higher than the mounting hole 51. The size of the hemispherical part at the top of the positioning post 52 is the same as that of the positioning hole.

[0040] The above solution is adopted: the elastic support of the spring 53 keeps the positioning column 52 in a raised state. The precise matching between the top hemisphere of the positioning column 52 and the positioning hole at the bottom of the adsorption catalytic bed 4 achieves stable positioning of the adsorption catalytic bed 4 at the corner of the moving tank 3, avoiding displacement of the adsorption catalytic bed 4 due to airflow impact during operation and ensuring the stability of equipment operation.

[0041] Reference Figures 5 to 8The switching component 6 includes a straight-line push groove 61 that penetrates the side of the reaction chamber. The push groove 61 is located in the middle of the inner side of the moving groove 3, and is situated between the desorption chamber 1 and the adsorption chamber 2, and is connected to the moving groove 3. An O-shaped mounting block 64 is fixedly connected to the outside of the reaction chamber. A cavity 65 is opened on the side of the mounting block 64 that is in contact with the reaction chamber. A ball bearing assembly 66 is slidably connected in the cavity 65. The ball bearing assembly 66 consists of multiple sets of balls that abut against each other. A slot 67 is opened on the side of the mounting block 64 away from the reaction chamber, and the slot 67 is connected to the cavity 65. Part of the adsorption catalyst bed 4 penetrates the push groove 61 and is fixedly connected to the ball bearing assembly 66. A push plate 68 is fixedly connected to one end of the ball bearing assembly 66, and the push plate 68 penetrates the slot 67. The side of the reaction chamber is fixedly connected to the push groove 61. A linear actuator 69 is fixedly connected to the reaction chamber and is located inside the O-shaped mounting block 64. The push plate 68 is fixedly connected to the movable end of the linear actuator 69. An O-shaped sealing groove 62 is opened on the outside of the reaction chamber. The sealing groove 62 is connected to the push groove 61. A sealing ring 63 is rotatably connected inside the sealing groove 62 and the sealing ring 63 blocks and seals the push groove 61. The push block 43 passes through the push groove 61 and the sealing ring 63 in sequence and is fixedly connected to the sealing ring 63. When the adsorption catalyst bed 4 moves in the moving groove 3, the sealing ring 63 moves synchronously in the sealing groove 62. There are four sets of push grooves 61, symmetrically distributed on both sides of the reaction chamber. There are two sets of sealing grooves 62. Each set of sealing grooves 62 is connected to the two sets of push grooves 61 symmetrically distributed on both sides.

[0042] The above scheme is adopted: the linear actuator 69 drives the push plate 68 to move the ball bearing assembly 66 and the push block 43, realizing the automatic switching of the adsorption catalyst bed 4 in the moving tank 3, reducing the intensity of manual operation. The sealing ring 63 is fixedly connected to the push block 43, so that the sealing ring 63 moves synchronously with the adsorption catalyst bed 4, and the I-shaped push tank 61 is dynamically sealed throughout the process to avoid gas leakage in the reaction chamber. The symmetrical layout of four sets of I-shaped push tanks 61 and two sets of O-shaped sealing tanks 62 ensures the stability and sealing of the adsorption catalyst bed 4 during the movement process.

[0043] The working principle of this invention is as follows: In the initial state, the two sets of adsorption catalytic beds 4 are positioned by positioning elements 5, one set is located in the desorption chamber 1, and the other set is located in the adsorption chamber 2. After the equipment is started, VOCs waste gas enters the adsorption chamber 2 through the VOCs inlet pipe 21, and rapidly diffuses under the guidance of the fan-shaped distribution of the diversion fins 23, uniformly contacting the adsorption catalytic beds 4 in the adsorption chamber 2. The VOCs pollutants are captured by the adsorption material 42 with catalyst, and the purified gas is discharged through the exhaust pipe 22. At the same time, the auxiliary gas required for desorption enters the desorption chamber 1 through the inlet hopper 13. The conical cross-section increases the gas flow rate, and then it is guided in a stepped manner by the inclined diversion fins 14 to fully contact the desorption chamber. Inside the adsorption catalytic bed 4, under the action of the catalyst, pollutants on the adsorption material 42 undergo an oxidation reaction to generate carbon dioxide and water. The liquid product is discharged through the drain pipe 11, and the gaseous product is discharged through the exhaust pipe 12. The adsorption catalytic bed 4 is regenerated simultaneously. When it is necessary to switch the operating conditions, the entry of VOCs waste gas into the adsorption chamber 2 is first stopped. Then, the linear actuator 69 is started, driving the push plate 68 to move in the slot 67, which drives the ball assembly 66 and the push block 43 to move along the straight push groove 61. The push block 43 pushes the adsorption catalytic bed 4 to slide along the C-shaped symmetrically distributed moving groove 3. During this process, the sealing ring 63 moves synchronously with the push block 43 in the O-shaped sealing groove 62, continuously sealing the push groove 61. When the adsorption catalyst bed 4 moves to the corner of the moving tank 3, the positioning column 52 is embedded in the positioning hole under the action of the spring 53, realizing the precise positioning of the adsorption catalyst bed 4. After the switching is completed, VOCs waste gas continues to enter the adsorption chamber 2. The adsorption catalyst bed 4 in the original adsorption chamber 2 enters the desorption chamber 1 for desorption and regeneration, and the adsorption catalyst bed 4 in the original desorption chamber 1 enters the adsorption chamber 2 for VOCs capture. This cycle repeats, realizing continuous operation of adsorption and desorption. Through the alternating switching and synchronous operation of the two sets of adsorption catalyst beds 4 in the moving tank 3, the parallel operation of adsorption filtration and desorption regeneration is realized, eliminating the need for frequent switching of operating conditions and shutdown bypass, completely eliminating the environmental risk of direct discharge of waste gas exceeding standards, and significantly improving efficiency. To improve the overall processing efficiency of the equipment, while avoiding the problems of increased energy consumption and control complexity caused by repeated adjustments to temperature and gas flow, it is perfectly adapted to the routine treatment needs of low-concentration, high-volume VOCs waste gas. Through the special arrangement design of the first diversion fin 14 and the second diversion fin 23, the contact area and reaction time between the gas and the adsorption catalyst bed 4 are greatly increased, enhancing the effect of pollutant capture, desorption and regeneration. Through the coordinated cooperation of the positioning component 5 and the switching component 6, the positioning of the adsorption catalyst bed 4 is accurate and the switching is smooth, reducing the probability of equipment failure. Through the integrated design of the desorption chamber 1 and the adsorption chamber 2, the overall footprint of the equipment is reduced, reducing the cost of on-site installation and subsequent maintenance.
