[0003] The specification of Chinese patent publication No. CN215505957U discloses a multistage industrial waste gas purification tower, which is convenient to clean the filter screen and replace the activated carbon plate through the cooperation between the installation groove, sealing plate, cleaning rod, fixed cylinder, through hole, brush roller and extrusion spring, and is convenient to use, and the utility model uses low cost, and is suitable for small enterprises to use.

[0004] The above-mentioned patent is a vertical tower structure, when the waste gas is adsorbed and purified, the filter screen and the activated carbon plate are installed and placed in parallel plate type, the waste gas enters the inside of the purification tower through the pipeline at the bottom, and is sequentially adsorbed and purified from bottom to top through the filter screen and the activated carbon plate, after the gas enters the inside of the purification tower, the waste gas is easy to discharge along the shortest path, so that the filter screen and the activated carbon plate appear local adsorption saturation, and the adsorption dead angle appears around, thereby leading to poor adsorption effect inside the purification tower. UTILITY MODEL CONTENTS

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that when the existing vertical tower structure purification tower treats waste gas, the waste gas is easy to discharge along the shortest path, so that the filter screen and the activated carbon plate appear local adsorption saturation, and the adsorption dead angle appears around, thereby leading to poor adsorption effect of the filter screen and the activated carbon inside the purification tower.

[0006] To address the aforementioned problems, this utility model provides a multi-stage adsorption purification device for waste gas from fluorocarbon color-coated aluminum coil production. The device includes a purification chamber, which is circular in shape. A partition is fixedly connected to the inner cavity of the purification chamber, and multiple mounting grooves are carved into the annular inner wall of the chamber. Adsorption meshes are inserted into these grooves. Two gas pipes are fixedly connected to the outer surface of the purification chamber, and one-way valves and gas detectors are installed on the gas pipes. A mounting ring is fixedly fitted onto the outer surface of the purification chamber, and a cover plate is provided at the top of the chamber. Two limiting grooves are carved into the upper end of the mounting ring, and sealing rings are installed within these grooves. The upper ends of the sealing rings are fixedly connected to the cover plate. Multiple sealing components are fixedly connected to the inner annular surface of the cover plate. Each sealing component includes a mounting plate fixedly connected to the inner annular surface of the cover plate and a positioning plate fixedly connected to the inner annular surface of the purification chamber. An insert plate is fixedly connected to the lower end of the mounting plate, and the lower end of the insert plate movably penetrates the positioning plate. A receiving groove is carved through the interior of the insert plate, and two rotating plates are rotatably connected within the receiving groove. A spring plate is fixedly connected between the two rotating plates.

[0007] In the aforementioned multi-stage adsorption purification device for waste gas from fluorocarbon coated aluminum coil production, compared to the existing vertical tower-shaped purification tower, the purification box in this invention is ring-shaped. After the waste gas enters the purification box, it can diffuse evenly along the circumference and turn multiple times inside the purification box, extending the travel path of the waste gas and effectively avoiding adsorption dead zones. Multiple adsorption nets are arranged radially, allowing the airflow to pass through all the adsorption nets, thereby carrying out multi-stage adsorption purification and effectively improving the purification effect.

[0008] As a further improvement of this application, the inner bottom wall of the purification box is chiseled with multiple positioning grooves, each corresponding to a multiple adsorption net. Positioning blocks are inserted into the positioning grooves, and the positioning blocks are fixedly connected to the adjacent adsorption nets.

[0010] As a further improvement of this application, the upper end of the rotating plate is rounded, and the upper end of the rotating plate is attached to the lower end of the positioning plate. The two rotating plates are symmetrically distributed in an inverted V-shape around the longitudinal center line of the mounting plate, and the elastic plate is located below the midpoint of the rotating plate.

[0011] As another improvement of this application, multiple adsorption nets are evenly distributed around the central axis of the purification box, with the upper end of the adsorption nets attached to the lower end of the cover plate.

[0013] In summary, in practical applications, waste gas enters the purification chamber through a duct and is separated by a partition, allowing the waste gas to diffuse evenly along the circumference. It then passes through multiple adsorption nets for adsorption and purification before being discharged through another duct. The waste gas undergoes multiple turns within the purification chamber, extending its travel path and effectively avoiding adsorption dead zones. The multiple adsorption nets are arranged radially, allowing the airflow to pass through all the nets, thus achieving multi-stage adsorption and purification and effectively improving the purification effect.

[0026] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0027] First implementation method:

[0028] Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The diagram illustrates a multi-stage adsorption purification device for waste gas from fluorocarbon-coated aluminum coil production. The device includes a purification box 1, which is circular in shape. A partition 2 is fixedly connected to the inner cavity of the purification box 1. Multiple mounting grooves 3 are carved into the annular inner wall of the purification box 1. These grooves facilitate the installation and removal of adsorption nets 4. Adsorption nets 4 are inserted into the mounting grooves 3. The adsorption nets 4 can be made of various materials such as activated carbon, bamboo charcoal, and alumina, which can be selected by technicians according to their needs. The multiple adsorption nets 4 are evenly distributed around the central axis of the purification box 1. The upper end of each adsorption net 4 is attached to the lower end of a cover plate 8, allowing multiple adsorption nets 4 to be evenly distributed around the central axis of the purification box 1. The adsorption nets 4 are installed radially inside the purification box 1, facilitating multi-stage purification of exhaust gas through multiple adsorption nets 4, effectively improving the purification effect. The inner bottom wall of the purification box 1 has multiple positioning grooves corresponding to multiple adsorption nets 4, with positioning blocks 16 inserted into each groove. The positioning blocks 16 are fixedly connected to adjacent adsorption nets 4, limiting and fixing the adsorption nets 4, effectively improving the stability of the adsorption nets 4 during installation. Two air pipes 5 are fixedly connected to the outer surface of the purification box 1, each located between two adjacent adsorption nets 4, and each air pipe 5 is located on a partition 2. On both sides, partitions 2 separate the interior of the purification chamber 1, making it a one-way channel. Exhaust gas enters the purification chamber 1 through a gas pipe 5, and then travels along the circumference of one side of partition 2 to the other side, effectively extending the gas's path. This allows the exhaust gas to pass through multiple adsorption nets 4 sequentially, thereby effectively improving the purification effect. A one-way valve and a gas detector 6 are installed on the gas pipe 5. Those skilled in the art can select a suitable model of one-way valve according to actual needs, such as D341X-10C. The gas detector 6, such as the KQ500, has a one-way valve that makes it difficult for the gas in the gas pipe 5 to reverse. The gas detector 6 can detect the waste gas inside the two gas pipes 5, compare the waste gas content in the two gas pipes 5, and determine whether the adsorption net 4 has reached saturation. The outer surface of the purification box 1 is fixedly fitted with an installation ring 7, and the upper end of the purification box 1 is provided with a cover plate 8. The upper end of the installation ring 7 is chiseled with two limiting grooves, and a sealing ring 9 is provided in the limiting groove. The upper end of the sealing ring 9 is fixedly connected to the cover plate 8. The sealing ring 9 can effectively improve the sealing performance of this utility model and effectively prevent the waste gas from escaping during the purification process.

[0029] Figure 1 , Figure 2 , Figure 3 , Figure 4 ,Figure 6 and Figure 7 The cover plate 8 has multiple sealing components fixedly connected to its inner ring surface. Each sealing component includes a mounting plate 10 fixedly connected to the inner ring surface of the cover plate 8 and a positioning plate 11 fixedly connected to the inner ring surface of the purification chamber 1. A mounting plate 12 is fixedly connected to the lower end of the mounting plate 10, and the lower end of the mounting plate 12 movably passes through the positioning plate 11. A receiving groove 13 is carved through the interior of the mounting plate 12, and two rotating plates 14 are rotatably connected within the receiving groove 13. A spring plate 15 is fixedly connected between the two rotating plates 14. The upper ends of the rotating plates 14 are rounded, and the upper... The end of the plate 14 is attached to the lower end of the positioning plate 11. The two rotating plates 14 are symmetrically distributed in an inverted V shape around the longitudinal center line of the mounting plate 10. The elastic plate 15 is located below the midpoint of the rotating plate 14. When installing the cover plate 8, the cover plate 8 is placed above the purification box 1, so that the insert plate 12 passes downward through the positioning plate 11. The two rotating plates 14 are squeezed and rotate inward, causing the elastic plate 15 to deform inward until the rotating plate 14 is located below the positioning plate 11. The rotating plate 14 is reset, thereby limiting and fixing the insert plate 12, so that the cover plate 8 is attached to the purification box 1.

[0030] During the adsorption and purification of waste gas, the waste gas enters the purification chamber 1 through one of the gas pipes 5. It is then separated by a partition 2, allowing the waste gas to diffuse evenly along the circumference. The waste gas passes through multiple adsorption nets 4 for adsorption and purification, and then exits through another gas pipe 5. The waste gas undergoes multiple turns inside the purification chamber 1, extending its travel path and effectively avoiding adsorption dead zones. The multiple adsorption nets 4 are arranged radially, allowing the airflow to pass through all the adsorption nets 4, thus performing multi-stage adsorption and purification, effectively improving the purification effect. The gas detector 6 on the gas pipe 5 compares the waste gas content in the two gas pipes 5 to determine whether the adsorption nets 4 have reached saturation. If the adsorption nets 4 have reached saturation, the two rotating plates 14 can be pressed inward, causing the elastic plate 15 to deform and rotate inward into the receiving groove 13. Then, the cover plate 8 is pulled upward to expose the interior of the purification chamber 1, making it convenient for staff to replace the adsorption nets 4 and perform maintenance on the interior of the purification chamber 1.

[0031] Second implementation method:

[0032] This embodiment adds a pressure strip 17 and a sealing sleeve 18 to the first embodiment, while the rest remains the same as the first embodiment.

[0033] Figure 8 , Figure 9 and Figure 10As shown: A pressure strip 17 is fixedly connected to the upper end of the adsorption net 4. The upper end of the pressure strip 17 movably passes through the cover plate 8 and is fixedly connected to a handle. The handle makes it easy for the operator to pull the adsorption net 4. A sealing sleeve 18 is fixedly fitted on the outer surface of the pressure strip 17. The sealing sleeve 18 can effectively improve the sealing effect between the pressure strip 17 and the cover plate 8, effectively preventing the exhaust gas from escaping through the gap between the pressure strip 17 and the cover plate 8 during the adsorption process, thereby effectively improving the sealing performance of this utility model.

[0034] When it is necessary to replace the adsorption net 4, the handle can be pulled directly to remove the pressure strip 17 and the adsorption net 4, thereby replacing the adsorption net 4, which effectively improves the replacement efficiency and facilitates the use of staff.

[0035] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
