Description

Technical Field

[0001] This utility model relates to the field of polyphenylsulfone resin production technology, and in particular to an activated carbon adsorption device for the tail gas of polyphenylsulfone resin production. Background Technology

[0002] In the field of polyphenylene sulfone (PPS) resin production technology, tail gas treatment is a crucial step in ensuring the environmental friendliness and safety of production. Currently, traditional activated carbon adsorption devices for PPS resin production tail gas have many shortcomings in practical applications.

[0003] Regarding activated carbon replacement, existing devices typically require replacing all the activated carbon in the adsorption box at once. This not only wastes a large amount of unsaturated activated carbon, increasing production costs, but also involves a cumbersome replacement process that consumes significant time and manpower, leading to reduced production efficiency. The uneven distribution of exhaust gas within the adsorption box prevents the activated carbon from fully contacting the exhaust gas, resulting in low utilization rates in some areas and premature adsorption saturation in others, thus affecting the overall adsorption effect and exhaust gas treatment efficiency. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides an activated carbon adsorption device for the tail gas of polyphenylsulfone resin production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An activated carbon adsorption device for the tail gas of polyphenylsulfone resin production includes an activated carbon adsorption box, which is rotatably mounted on a support. One end of the activated carbon adsorption box is provided with a tail gas inlet pipe, and the other end is provided with a tail gas outlet pipe. The top and bottom ends of the activated carbon adsorption box are respectively provided with an activated carbon addition port and an activated carbon discharge port. The activated carbon discharge port is located on the side of the activated carbon adsorption box near the tail gas inlet pipe. Inside the activated carbon adsorption box, multiple baffles are rotatably mounted via a rotating shaft. The baffles are provided with mesh holes, and the multiple baffles are spliced ​​together to form a flat whole.

[0007] Preferably, a rotary motor is fixed on the support, the output shaft of the rotary motor is fixed to the activated carbon adsorption box, and a sleeve is also fixed on the support.

[0008] Preferably, a first spur gear is fixed on the sleeve, and the output shaft of the rotary motor passes through the sleeve and the first spur gear.

[0009] Preferably, the bottom end of the rotating shaft extends to the outside of the activated carbon adsorption box and is fixed with a first bevel gear, and a synchronous shaft is rotatably installed below the activated carbon adsorption box, with multiple second bevel gears fixed on the synchronous shaft.

[0010] Preferably, a plurality of second bevel gears mesh with the first bevel gear in a one-to-one correspondence, and a second spur gear is fixed at one end of the synchronous shaft. The first spur gear and the second spur gear mesh with each other, and the two have the same diameter.

[0011] Preferably, a gas distribution plate is installed inside the activated carbon adsorption box at the corresponding positions of the exhaust gas inlet pipe and the exhaust gas outlet pipe. The gas distribution plate is provided with multiple gas inlets and outlets. A vibration motor is fixedly installed on one side of the outer wall of the activated carbon adsorption box. Airtight baffles can be detachably installed on the activated carbon adding port and the activated carbon discharging port of the activated carbon adsorption box.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model's activated carbon adsorption device for polyphenylsulfone resin production tail gas achieves partial activated carbon replacement through a unique structural design. During the activated carbon replacement process, only the portion of activated carbon with higher saturation near the tail gas inlet pipe is discharged, avoiding the need to replace all activated carbon at once, significantly saving activated carbon usage and reducing production costs. Simultaneously, since frequent large-scale activated carbon replacement operations are unnecessary, labor intensity and replacement time are reduced, improving production efficiency and enabling the equipment to operate more efficiently.

[0014] 2. The gas distribution plate inside the device ensures that the exhaust gas is evenly distributed within the activated carbon adsorption box, guaranteeing sufficient contact between the exhaust gas and the activated carbon, improving the utilization rate of the activated carbon, and effectively enhancing the adsorption and purification effect of the exhaust gas. Furthermore, during the discharge and addition of activated carbon, the vibration motor drives the activated carbon adsorption box to vibrate, accelerating the discharge of activated carbon and simultaneously increasing its compactness within the adsorption box, further enhancing the filtration and adsorption capacity, and ensuring the quality and stability of the exhaust gas treatment.

[0015] 3. Employing a clever gear transmission and linkage design, when the rotary motor drives the activated carbon adsorption box to switch between vertical and horizontal positions, the meshing of the first and second spur gears, and the engagement of the second and first bevel gears, automatically drives the rotating shaft to rotate, allowing the baffles to adjust their state at the appropriate time. This linkage method, which requires no additional controller, not only simplifies the equipment structure and reduces the probability of failure, but also ensures the stability and reliability of the equipment operation, enabling the device to work in a coordinated and orderly manner under different operating conditions.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Example 1

[0026] Reference Figure 1-6An activated carbon adsorption device for the tail gas of polyphenylsulfone resin production includes an activated carbon adsorption box 2, which is rotatably mounted on a support 1. One end of the activated carbon adsorption box 2 is provided with a tail gas inlet pipe 4, and the other end of the activated carbon adsorption box 2 is provided with a tail gas outlet pipe 401. The top and bottom ends of the activated carbon adsorption box 2 are respectively provided with an activated carbon addition port 201 and an activated carbon discharge port 202. The activated carbon discharge port 202 is located on the side of the activated carbon adsorption box 2 near the tail gas inlet pipe 4. Inside the activated carbon adsorption box 2, multiple baffles 301 are rotatably mounted via a rotating shaft 3. The baffles 301 are provided with mesh holes, and the multiple baffles 301 are spliced ​​into a flat whole.

[0027] Activated carbon is added to the interior of the activated carbon adsorption box 2 through the activated carbon addition port 201. Both sides of the baffle 301 have activated carbon addition ports 201, allowing the ports to be filled with activated carbon. After filling, exhaust gas is introduced into the activated carbon adsorption box 2 through the exhaust gas inlet pipe 4. After adsorption by the activated carbon, the gas is discharged through the exhaust gas outlet pipe 401. At this time, the activated carbon adsorption box 2 is in a horizontal state. When it is necessary to replace the activated carbon, the activated carbon discharge port 202 is opened. Since the activated carbon discharge port 202 is located on the side of the activated carbon adsorption box 2 closest to the exhaust gas inlet pipe 4, only the activated carbon on one side of the baffle 301 will be discharged. Because this side is close to the exhaust gas inlet pipe 4, the exhaust gas first passes through the activated carbon on this side, resulting in a higher saturation level. After discharging, the activated carbon addition port 201 and the activated carbon outlet 202 are closed. The activated carbon discharge port 202 is used to rotate the activated carbon adsorption box 2 to a vertical position, so that the side of the activated carbon adsorption box 2 closest to the exhaust gas inlet pipe 4 faces downwards. The rotating shaft 3 is then driven to rotate 90 degrees, making the baffles 301 parallel to each other. The remaining activated carbon moves to the side closest to the exhaust gas inlet pipe 4 due to gravity. Then the rotating shaft 3 is driven to rotate back to its original position, and the activated carbon adsorption box 2 is driven to rotate to a horizontal position to reset. The activated carbon addition port 201 on the side of the activated carbon adsorption box 2 away from the exhaust gas inlet pipe 4 is opened, and new activated carbon is added, thus completing the replacement of the activated carbon. After replacement, the activated carbon on the side closest to the exhaust gas inlet pipe 4 is still in a state of high saturation. Therefore, each replacement only replaces the part that needs to be replaced urgently, without having to replace all the activated carbon at once, which saves activated carbon and improves replacement efficiency.

[0028] Example 2

[0029] Reference Figure 1-6The difference between this embodiment and embodiment 1 is that a rotary motor 101 is fixed on the bracket 1, the output shaft of the rotary motor 101 is fixed to the activated carbon adsorption box 2, a sleeve 102 is also fixed on the bracket 1, a first spur gear 1021 is fixed on the sleeve 102, the output shaft of the rotary motor 101 passes through the sleeve 102 and the first spur gear 1021, the bottom end of the rotating shaft 3 extends to the outside of the activated carbon adsorption box 2 and a first bevel gear 302 is fixed thereon, a synchronous shaft 303 is rotatably installed below the activated carbon adsorption box 2, a plurality of second bevel gears 304 are fixed on the synchronous shaft 303, the plurality of second bevel gears 304 mesh with the first bevel gear 302 one by one, and a second spur gear 305 is fixed at one end of the synchronous shaft 303, the first spur gear 1021 and the second spur gear 305 mesh with each other and have the same diameter;

[0030] The activated carbon adsorption box 2 can be rotated by the rotary motor 101, thus switching between vertical and horizontal states. When the activated carbon adsorption box 2 is in the horizontal state, multiple baffles 301 are spliced ​​into a flat whole, acting as partitions. When the activated carbon adsorption box 2 rotates to the vertical state, since the first spur gear 1021 and the second spur gear 305 mesh with each other and have the same diameter, the synchronous shaft 303 can also rotate 90 degrees. Then, through the meshing of the second bevel gear 304 and the first bevel gear 302, the rotating shaft 3 can be rotated 90 degrees. Thus, through the linkage, it is ensured that when the activated carbon adsorption box 2 rotates to the vertical state, the multiple baffles 301 automatically rotate to a parallel state, allowing activated carbon to pass through the gap between adjacent baffles 301. No additional controller is required, and the operation is stable.

[0031] Among them, gas distribution plates 402 are installed inside the activated carbon adsorption box 2 at positions corresponding to the tail gas inlet pipe 4 and the tail gas outlet pipe 401. The gas distribution plates 402 are provided with multiple gas inlets and outlets 403. A vibration motor 204 is fixedly installed on one side of the outer wall of the activated carbon adsorption box 2. Airtight baffles 203 can be detachably installed on the activated carbon addition port 201 and the activated carbon discharge port 202 of the activated carbon adsorption box 2.

[0032] When discharging and adding activated carbon, the vibration motor 204 can be turned on to drive the activated carbon adsorption box 2 to rotate. By driving the activated carbon to vibrate, the discharge is accelerated and the compactness of the activated carbon is improved, thereby enhancing the filtration and adsorption effect.
