Description

Technical Field

[0001] This utility model belongs to the field of organic waste gas treatment technology, specifically relating to an activated carbon separation tower. Background Technology

[0002] In industrial production and daily life, emissions of waste gases such as formaldehyde, benzene, TVOC (total volatile organic compounds), ammonia, and hydrogen sulfide are widespread, seriously threatening the environment and human health. Activated carbon separation towers, due to the adsorption properties of activated carbon, have become key equipment for treating these waste gases.

[0003] However, the existing activated carbon separation tower has obvious defects in its internal structural design:

[0004] 1. Uneven airflow distribution and unreasonable design of the flow guide and airflow channels inside the tower. After the exhaust gas enters, it is easy to form a high-speed concentrated impact in some areas, which leads to premature adsorption saturation of activated carbon in some areas, while the activated carbon in other areas does not play a full role, resulting in poor overall purification effect and difficulty in meeting environmental protection requirements.

[0005] Second, the structure has poor stability. Under the impact of airflow, the stress in local areas is too concentrated. Long-term operation may lead to problems such as cracks and deformation, resulting in some exhaust gas being emitted without filtration, which poses a potential hazard to the environment and human health. Utility Model Content

[0006] The purpose of this invention is to provide an activated carbon separation tower that solves the technical problems of uneven airflow distribution and poor structural stability in the prior art.

[0007] This utility model discloses an activated carbon separation tower, comprising:

[0008] The tower body has a processing chamber inside, and air outlets and air inlets are provided on the front and rear sides respectively, and a pair of feed inlets and a pair of discharge outlets are provided on the top and bottom sides respectively.

[0009] A partition frame is provided in the processing chamber and forms a partition between the air outlet and the air inlet;

[0010] Two cover plates are respectively installed at the two feed inlets;

[0011] Two gate valves are respectively installed at the two discharge ports;

[0012] The partition skeleton includes:

[0013] A partition is vertically installed within the processing chamber;

[0014] A pair of containment boxes are symmetrically arranged in a figure-eight shape on both sides of the middle partition, with their flared ends facing the air inlet. Each containment box has multiple perforations on its circumferential sidewall. The diameter of the perforations is smaller than the particle size of the activated carbon. The upper and lower sides of the containment box are respectively connected to the feed inlet and the discharge outlet.

[0015] Two side partitions are respectively installed between the outer wall of the accommodating box and the inner wall of the tower.

[0016] This application makes the exhaust gas distribution more uniform, effectively suppresses turbulence generation, eliminates angles, avoids the formation of flow dead zones, allows the airflow to flow along a smoother channel, reduces airflow collisions and turns, and makes the airflow channel wider and smoother, reducing airflow resistance. This allows the exhaust gas to pass through the activated carbon layer with lower pressure loss, improving the equipment's processing capacity and operating efficiency. It also disperses stress, making load transfer more continuous, thereby improving the structure's fatigue resistance and enhancing the stability of the internal structure.

[0017] Based on the above technical solution, the solution of this application can be further improved as follows:

[0018] Preferably, the container is a rectangular column structure that runs vertically through the container, and the middle partition and side partitions are both located on the vertical edges of the container. This design makes the interior of the container more regular, thereby reducing residual blockage, improving the conversion efficiency and distribution uniformity of activated carbon, avoiding the formation of sharp angles, and improving the stability of airflow.

[0019] Preferably, the container includes:

[0020] The grid frame has a rectangular structure.

[0021] Four surrounding panels are arranged around the inside of the grid frame and connected end to end in sequence, with multiple perforations evenly distributed on the surface; this solution ensures overall strength and stability, and the structure is relatively simple, easy to manufacture and process.

[0022] Preferably, the discharge port has a bucket-shaped structure that is wider at the top and narrower at the bottom, and is adapted to the bottom opening of the container. This design guides and gathers the activated carbon, preventing it from accumulating or getting stuck, ensuring that the activated carbon can be discharged smoothly, and also closely follows the flow path of the activated carbon, reducing residue at the connection between the discharge port and the container.

[0023] Preferably, it includes:

[0024] The base is installed on the bottom surface of the tower body;

[0025] A ladder is installed on the side of the tower.

[0026] A guardrail is installed on the top surface of the tower body and surrounds the feed inlet, with an entrance / exit on one side corresponding to the ladder. This solution provides stable support, ensures the stability of the tower body, allows personnel to easily reach the top of the tower body for operation, and provides reliable safety protection for tower top operations.

[0027] Preferably, two maintenance manholes are provided on the outer side of the tower body, located on both sides of the partition frame, and a sealing cover is detachably installed on the outside of the maintenance manhole. This solution provides a convenient passage for daily maintenance and troubleshooting, making it easy for operators to conduct a comprehensive inspection and maintenance of the areas on both sides of the partition frame, greatly improving maintenance efficiency, while taking into account both the convenience of maintenance and the airtightness of the equipment.

[0028] Preferably, the front sidewall of the tower body has a truncated square pyramidal structure, and the air outlet is located at the center of the front sidewall of the tower body. This design allows the gas to converge smoothly along the slope, reducing gas stagnation and eddy currents, improving flow smoothness and gas outlet uniformity, and avoiding uneven pressure distribution inside the tower, which would affect the activated carbon's treatment effect on waste gas.

[0029] Preferably, the gate valve comprises:

[0030] A flange is installed at the discharge port;

[0031] A gate is inserted laterally into the flange from the side of the flange, and the gate can be closed and opened by sliding within the flange.

[0032] A pad is provided at the other end of the gate;

[0033] A sleeve is provided on the side of the pad away from the pad;

[0034] The screw is rotatably mounted on the tower body, with one end threaded into the sleeve.

[0035] A handwheel is installed at the other end of the screw. This design enables precise control of the unloading process. By adjusting the opening degree of the gate, the discharge speed and flow rate of activated carbon can be controlled. It also has good sealing performance, which can prevent gas leakage and ensure the normal operation of the device.

[0036] Through the above technical solution, this utility model achieves the following beneficial effects:

[0037] 1. This application uses the figure-eight symmetrical design of the containment box to concentrate the exhaust gas along the inner surface of the containment box after it enters the treatment chamber, thereby forming a wall adhesion effect, which makes the airflow spread evenly on the surface of the activated carbon bed, making the exhaust gas distribution more uniform and effectively suppressing the generation of turbulence.

[0038] 2. This application eliminates the innermost angle formed when the two containment boxes are arranged in a V-shape by setting a partition, thereby avoiding the formation of flow dead zones, preventing eddies and airflow turbulence, allowing airflow to flow along a smoother channel, reducing airflow collisions and turning, and making the waste gas distribution more uniform; it also makes the airflow channel wider and smoother, thereby reducing airflow resistance, allowing waste gas to pass through the activated carbon layer with lower pressure loss, improving the equipment's processing capacity and operating efficiency;

[0039] 3. This application achieves a smooth transition between the two housing boxes by setting a partition plate, thereby dispersing stress and making load transfer more continuous, thus improving the fatigue resistance of the structure and enhancing the stability of the internal structure.

[0051] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0052] The terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as “first” or “second” may explicitly or implicitly include one or more of the stated features.

[0053] In this application, unless otherwise expressly specified and limited, the terms "installation" and "connection" 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 direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0054] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0055] Example:

[0056] like Figures 1 to 7 As shown in the embodiment of this application, an activated carbon separation tower is disclosed for the adsorption and purification of waste gas through the adsorption characteristics of activated carbon. It has the advantages of uniform airflow distribution and good structural stability. Its structure includes: tower body 1, partition frame 2, two cover plates 3 and two gate valves 4.

[0057] The tower body 1 has a processing chamber 101 inside, which provides a closed space for waste gas treatment; and an outlet 102 and an inlet 103 are respectively provided on the front and rear sides for waste gas to enter and purified gas to be discharged. A pair of feed inlets 104 and a pair of discharge outlets 105 are respectively provided on the upper and lower sides for loading and unloading activated carbon.

[0058] The partition frame 2 is located in the treatment chamber 101 and forms a partition between the air outlet 102 and the air inlet 103 to guide the flow path of the exhaust gas in the tower body 1 and improve the contact efficiency between the exhaust gas and the activated carbon.

[0059] Two cover plates 3 are respectively installed at the two feed inlets 104 to ensure that the feed inlets 104 can be tightly sealed after the activated carbon is filled, thereby ensuring the airtightness of the tower and preventing exhaust gas leakage.

[0060] Two gate valves 4 are respectively installed at two discharge ports 105. When it is necessary to replace the activated carbon, the discharge ports 105 are opened to allow the saturated activated carbon to be discharged smoothly. Under normal working conditions, the discharge ports 105 are closed to maintain the sealing of the tower.

[0061] Specifically, such as Figure 7 and Figure 8 As shown, the partition skeleton 2 includes:

[0062] The partition 21, which is vertically installed in the treatment chamber 101, is used to allow the exhaust gas to flow more evenly to the two side boxes 22 instead of concentrating in the central area. It also disperses stress through a smooth transition, making the load transfer more continuous, thereby improving the fatigue resistance of the structure and enhancing the stability of the internal structure.

[0063] A pair of containment boxes 22 are symmetrically arranged in a figure-eight shape on both sides of the central partition 21, with their flared ends facing the air inlet 103. Each containment box 22 has multiple perforations 2201 on its circumferential sidewall. The diameter of the perforations 2201 is smaller than the particle size of the activated carbon, which can ensure that the exhaust gas can fully contact the activated carbon through the perforations 2201 and prevent the activated carbon particles from leaking. The upper and lower sides of the containment box 22 are respectively connected to the feed inlet 104 and the discharge outlet 105, which facilitates the loading and unloading of activated carbon.

[0064] Two side baffles 23 are respectively installed between the outer wall of the container 22 and the inner wall of the tower body 1 to eliminate the gas short-circuit channel and guide the edge exhaust gas to flow into the container 22, so as to prevent the exhaust gas from bypassing the container 22 and being discharged directly from the outlet 102, thereby improving the adsorption efficiency of activated carbon.

[0065] The above technical solution has the following technical effects:

[0066] First, the figure-eight symmetrical design of the container 22 allows the exhaust gas to be concentrated along the inner surface of the container 22 after entering the treatment chamber 101, thereby forming a wall adhesion effect, which makes the airflow spread evenly on the surface of the activated carbon bed, making the exhaust gas distribution more uniform and effectively suppressing the generation of turbulence.

[0067] Second, by setting the partition plate 21, the innermost angle formed when the two containment boxes 22 are arranged in a V shape is eliminated, thereby avoiding the formation of flow dead zones, preventing eddies and airflow turbulence, allowing the airflow to flow along a smoother channel, reducing airflow collisions and turning, and making the waste gas distribution more uniform; it also makes the airflow channel wider and smoother, thereby reducing airflow resistance, allowing the waste gas to pass through the activated carbon layer with lower pressure loss, improving the equipment's processing capacity and operating efficiency;

[0068] Third, by setting the partition plate 21, a smooth transition is achieved between the two accommodating boxes 22, thereby dispersing the stress and making the load transfer more continuous, thus improving the fatigue resistance of the structure and enhancing the stability of the internal structure.

[0069] In some embodiments, such as Figure 7 As shown, the container 22 has a rectangular column structure that runs vertically through it, and the middle partition 21 and the side partition 23 are both located on the vertical edges of the container 22.

[0070] The shape design of the container 22 makes the interior of the container 22 regular, thereby reducing residual blockage and improving the replacement efficiency and distribution uniformity of activated carbon. Furthermore, by placing the partition on the edge, sharp angles are avoided, thereby improving the stability of airflow.

[0071] Based on the above embodiments, such as Figure 7 and Figure 8 As shown, the container 22 includes:

[0072] The grid frame 221, which has a rectangular structure, is used to provide a supporting skeleton, which can better withstand the weight of the internal activated carbon and the impact force of the external airflow, thus improving the overall strength and structural stability.

[0073] Four enclosure panels 222 are located around the inside of the grid frame 221 and are connected end to end to form a space for the activated carbon. Multiple perforations 2201 are evenly opened on the surface to ensure smooth gas flow.

[0074] The above structural design of the container 22 ensures overall strength and stability, and the structure is relatively simple, making it easy to manufacture and process.

[0075] Based on the above embodiments, such as Figure 5As shown, the discharge port 105 has a bucket-shaped structure that is larger at the top and smaller at the bottom, and it is compatible with the bottom opening of the container 22.

[0076] Preferably, the outer periphery of the discharge port 105 is provided with multiple reinforcing ribs, thereby improving the structural strength, enhancing the load-bearing capacity, and ensuring the structural stability.

[0077] The above design can better receive the activated carbon falling from the bottom of the container 22, and guide and gather the activated carbon to avoid accumulation or jamming, ensuring that the activated carbon can be discharged smoothly. It can also closely fit the flow path of the activated carbon, reducing the residue at the connection between the discharge port 105 and the container 21.

[0078] In some embodiments, such as Figure 1 and Figure 2 As shown, it includes:

[0079] The base 5 is installed on the bottom surface of the tower body 1 to provide a stable support foundation for the entire activated carbon separation tower, ensuring that the tower body 1 remains stable and avoiding accidents such as tilting, shaking or even collapse.

[0080] Ladder 6, installed on the side of tower 1, provides operators with access to the top of tower 1 and has a safety guard to prevent falls during climbing.

[0081] The guardrail 7 is installed on the top surface of the tower body 1 and surrounds the feed inlet 104. It is used to provide safety protection for personnel operating at the top of the tower. It has an entrance 701 on one side corresponding to the ladder 6, which facilitates the operator to enter the guardrail 7 from the ladder 6 and also facilitates safe exit after the operation is completed.

[0082] The above-mentioned setup provides stable support, ensuring the stability of tower 1, and allows personnel to easily reach the top of tower 1 for operations, while also providing reliable safety protection for tower top operations.

[0083] In some embodiments, such as Figures 1-5 As shown, two maintenance manholes 106 are opened on the outside of the tower body 1, located on both sides of the partition frame 2 respectively, and a sealing cover 8 is detachably installed on the outside of the maintenance manhole 106.

[0084] Preferably, one side of the sealing cover 8 is hinged to the tower body 1, which improves the portability of opening and closing the sealing cover 8 and enhances maintenance efficiency.

[0085] The above-mentioned setup provides a convenient channel for daily maintenance and troubleshooting, making it easy for operators to conduct a comprehensive inspection and maintenance of the areas on both sides of the partition frame 2, greatly improving maintenance efficiency. Furthermore, the removable sealing cover 8 balances the convenience of maintenance with the airtightness of the equipment.

[0086] Preferably, the outlet 102, inlet 103, feed inlet 104 and maintenance manhole 106 are all provided with connecting flanges, which improves the sealing performance and can effectively prevent gas leakage from the device.

[0087] In some embodiments, such as Figure 1 As shown, the front sidewall 107 of the tower body 1 has a truncated square pyramidal structure, and the air outlet 102 is located at the center of the front sidewall 107.

[0088] The above design allows the gas to converge smoothly along the slope, thereby reducing gas stagnation and eddy currents at the corners or edges of the tower, improving the smoothness of gas flow, and also improving the uniformity of gas output. This avoids uneven pressure distribution inside the tower, which would affect the treatment effect of activated carbon on waste gas.

[0089] In some embodiments, such as Figure 6 As shown, gate valve 4 includes:

[0090] Flange 41, which is installed at discharge port 105, provides a stable platform for the connection of gate valve 4 and waste collection equipment;

[0091] Gate 42, one end of which is inserted laterally into the flange 41 from the side of the flange 41, and the gate 42 is used to close and open the discharge port 105 by sliding within the flange 41.

[0092] Pad 43, which is located at the other end of the gate 42, serves to provide support and cushioning.

[0093] The sleeve 44 is located on the side of the pad 43 away from the pad 43 and is used to convert the rotational motion of the screw 45 into the linear motion of the gate 42.

[0094] The screw 45 is rotatably mounted on the tower body 1, and one end is threadedly connected to the sleeve 44 to drive the sleeve 44 to move, thereby controlling the action of the gate 42.

[0095] The handwheel 46, which is mounted on the other end of the screw 45, is used to enable the operator to easily and effortlessly control the opening and closing of the gate 42.

[0096] When it is necessary to close the discharge port 105, the operator turns the handwheel 46 clockwise, and the screw 45 rotates accordingly. Since the screw 45 is threadedly connected to the sleeve 44, the sleeve 44 will move along the screw 45 towards the gate 42, pushing the pad 43 and the gate 42 to move together until the gate 42 is fully inserted into the flange 41 and closes the discharge port 105.

[0097] When it is necessary to open the discharge port 105, the operator turns the handwheel 46 counterclockwise, the screw 45 rotates in the opposite direction, the sleeve 44 moves along the screw 45 away from the gate 42, driving the gate 42 to be pulled out, the discharge port 105 is opened, and the activated carbon can be discharged.

[0098] The above-mentioned design of gate valve 4 enables precise control of the unloading process. By adjusting the opening degree of gate 42, the discharge speed and flow rate of activated carbon can be controlled. It also has good sealing performance, which can prevent gas leakage and ensure the normal operation of the device.

[0099] Further details regarding this application are as follows:

[0100] Purification process: The waste gas to be treated enters the treatment chamber 101 inside the tower body 1 through the air inlet 103, and is then guided by the figure-eight flared opening to enter the containment boxes 22 on both sides evenly. Activated carbon adsorbs the harmful substances in the waste gas. The purified gas after adsorption and filtration continues to flow forward and reaches the front side wall 107 area of ​​the tower body. The front side wall 107 has a converging effect on the gas, making the purified gas flow more smoothly to the air outlet 102.

[0101] Activated carbon replacement: When the activated carbon is saturated, the discharge port 105 is opened by operating the gate valve 4, so that all the activated carbon in the container 22 is discharged from the discharge port 105. Then, the gate valve 4 is operated to close the discharge port 105. The operator goes to the top of the tower via the ladder 6, opens the cover plate 3, and loads new activated carbon into the container 22 through the feed port 104. After the filling is completed, the feed port 104 is closed again using the cover plate 3. At this time, the tower body 1 returns to normal working condition.
