[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 The present invention provides the following technical solution:

[0027] A self-cleaning honeycomb structured packing phenol recovery and separation component includes a mounting base 1, a controller 2 is provided on the front side of the top of the mounting base 1, a processing tower 3 is fixedly connected to the left side of the top of the mounting base 1, a honeycomb structured packing body 4 is provided inside the processing tower 3, and a switching component 5 is fixedly connected to the right side of the top of the mounting base 1. The switching component 5 includes a conduit 51, and one end of the conduit 51 located inside the processing tower 3 is fixedly connected to a cleaning component 6.

[0028] The cleaning component 6 includes a rotary joint 61, the fixed end of which is fixedly connected to the conduit 51, the rotating end of which is fixedly connected to a metal pipe 62, the bottom surface of which is fixedly connected to a plurality of connecting pipes 63 in a ring-shaped arrangement, a support ring 64 fixedly connected to the outside of the connecting pipes 63, and a water outlet pipe 65 fixedly connected to the bottom of the surface of the connecting pipes 63, wherein the number of water outlet pipes 65 is set to several and evenly distributed.

[0029] In this embodiment: By setting the cleaning component 6, the rotary joint 61 is a key component connecting the conduit 51 and the metal pipe 62. Its fixed end is fixedly connected to the conduit 51, and its rotating end is fixedly connected to the metal pipe 62, allowing the metal pipe 62 to rotate while the conduit 51 remains fixed. This provides a basis for the subsequent rotational cleaning of the connecting pipe 63 and the outlet pipe 65. The metal pipe 62, as the main transmission channel for the cleaning liquid or absorbent, undertakes the important task of transporting the liquid from the rotary joint 61 to each connecting pipe 63, ensuring that the liquid can be evenly distributed into each connecting pipe 63, thus guaranteeing the subsequent comprehensive cleaning or absorption reaction. The connecting pipes 63 are arranged in a ring at the bottom of the metal pipe 62, acting as a bridge connecting the metal pipe 62 and the outlet pipe 65, further allowing the liquid transmitted from the metal pipe 62 to be further... The support ring 64 provides stable support for the cleaning component 6. When the cleaning component 6 rotates, the support ring 64 ensures the stability of the entire cleaning component 6 and prevents the cleaning component 6 from shaking or shifting due to centrifugal force or other factors generated by rotation. The water outlet pipe 65 is the final spray point for the cleaning liquid or absorbent. Under normal working conditions of phenol recovery and separation, the water outlet pipe 65 sprays the absorbent, allowing it to fully contact and react with the phenol-containing waste gas to achieve phenol recovery and separation. When cleaning is required, the water outlet pipe 65 can spray the cleaning liquid to clean the honeycomb structured packing body 4, removing impurities and polymer blockages in its pores, restoring the specific surface area and mass transfer efficiency of the packing. Its uniform distribution ensures that the cleaning liquid or absorbent covers all parts of the honeycomb structured packing body 4, improving the cleaning and recovery separation effect.

[0030] Specifically, such as Figure 1 , Figure 3As shown, a centrifugal pump 52 is fixedly connected to the end of the conduit 51 away from the rotary joint 61, and the conduit 51 is fixedly connected to the outlet end of the centrifugal pump 52. The centrifugal pump 52 is fixedly connected to the top of the mounting base 1.

[0031] Specifically, such as Figure 1 , Figure 3 As shown, an absorbent storage tank 53 is fixedly connected to the rear side of the top of the mounting base 1, and a first extraction pipe 54 is fixedly connected to the front side of the absorbent storage tank 53. The other end of the first extraction pipe 54 is fixedly connected to the suction end of the centrifugal pump 52.

[0032] Specifically, as shown in Figure 3, a cleaning fluid storage tank 55 is fixedly connected to the right side of the absorbent storage tank 53, and a second extraction pipe 56 is fixedly connected to the front side of the cleaning fluid storage tank 55. The other end of the second extraction pipe 56 is fixedly connected to the first extraction pipe 54, and a reversing valve 57 is provided at the connection between the second extraction pipe 56 and the first extraction pipe 54.

[0033] In this embodiment: Through the above settings, the centrifugal pump 52 can provide power for the delivery of absorbent or cleaning liquid. During the phenol recovery and separation process, the absorbent needs to be delivered from the absorbent storage tank 53 to the cleaning component 6 in the treatment tower 3 so as to fully contact and react with the phenol-containing waste gas. During the cleaning process, the cleaning liquid needs to be delivered from the cleaning liquid storage tank 55 to the cleaning component 6 to clean the honeycomb structured packing body 4. The absorbent storage tank 53 stores the absorbent used for phenol recovery and separation. The absorbent is the key substance for realizing phenol recovery. It can chemically react with phenolic substances in the phenol-containing waste gas to separate the phenol from the waste gas. The function of the first extraction pipe 54 is to deliver the absorbent from the absorbent storage tank 53 to the centrifugal pump 52, so that the centrifugal pump 52 can extract the absorbent and deliver it to the cleaning component 6 in the treatment tower 3 to realize the function of phenol recovery and separation. The cleaning liquid storage tank 55 is used to store the phenol for the honeycomb structured packing. The cleaning fluid used for cleaning the main body 4 is introduced from the cleaning fluid storage tank 55 into the first extraction pipe 54 when the honeycomb structured packing main body 4 needs cleaning. The fluid is then transported to the cleaning component 6 in the treatment tower 3 via the centrifugal pump 52, allowing the cleaning fluid to clean the honeycomb structured packing main body 4. The reversing valve 57 switches between the absorbent and the cleaning fluid. During normal phenol recovery and separation, the reversing valve 57 connects the first extraction pipe 54 to the absorbent storage tank 53, allowing the absorbent to be transported to the treatment tower 3. When cleaning of the honeycomb structured packing main body 4 is required, the reversing valve 57 switches channels, connecting the second extraction pipe 56 to the first extraction pipe 54, allowing the cleaning fluid to be transported to the treatment tower 3. This allows for control according to actual needs, enabling flexible switching between the phenol recovery and separation and cleaning processes, improving the equipment's versatility and efficiency.

[0034] Specifically, such as Figure 4 , Figure 6 As shown, a fixed ring 7 is fixedly connected inside the processing tower 3, and a support ring 64 is rotatably connected inside the fixed ring 7. A mounting plate 8 is fixedly connected to the right side of the top of the support ring 64. A drive motor 9 is fixedly connected inside the mounting plate 8, and a transmission shaft 10 is fixedly connected to the output end of the drive motor 9.

[0035] Specifically, such as Figure 6 As shown, a first bevel gear 11 is fixedly sleeved on the surface of the metal tube 62, and a second bevel gear 12 is meshed with the top of the first bevel gear 11. The left side of the transmission shaft 10 is fixedly connected to the right side of the second bevel gear 12.

[0036] In this embodiment: Through the above settings, the fixing ring 7 can provide stable support and precise positioning for the support ring 64, ensuring that the support ring 64 can rotate smoothly inside, thus guaranteeing the stability of the cleaning component 6 during operation. The mounting plate 8 can provide a fixed mounting platform for the drive motor 9, preventing the drive motor 9 from becoming loose or shifting due to vibration or other reasons during operation, thus ensuring the normal operation of the drive motor 9. The output end of the drive motor 9 is fixedly connected to the transmission shaft 10. When the drive motor 9 starts, it can convert electrical energy into mechanical energy and transmit the power to the second bevel gear through the transmission shaft 10. 12. The second bevel gear 12 rotates with the drive motor 9, thereby driving the first bevel gear 11 and the metal tube 62 to rotate. When the metal tube 62 rotates, it will drive the connecting pipe 63, the support ring 64 and the water outlet pipe 65 to rotate together. During the cleaning process, the rotating water outlet pipe 65 can evenly spray the cleaning liquid onto all parts of the honeycomb structured packing, achieving all-round cleaning, avoiding cleaning dead corners and improving the cleaning effect. During the phenol recovery process, the rotating water outlet pipe 65 can make the absorbent contact with the phenol-containing waste gas more evenly, enhance the mass transfer effect and improve the efficiency of phenol recovery and separation.

[0037] Specifically, such as Figure 4 , Figure 6 As shown, L-shaped rods 13 are fixedly connected to the front and rear sides of the top of the fixed ring 7, and a protective box 14 is fixedly connected to the side of the two L-shaped rods 13 that are close to each other. The first bevel gear 11 and the second bevel gear 12 are located inside the protective box 14, and the metal tube 62 and the transmission shaft 10 are rotatably connected to the protective box 14 through bearings.

[0038] Specifically, such as Figure 2 As shown, a guide cover 15 is fixedly connected to the top of the interior of the processing tower 3, and the inner wall of the guide cover 15 is set in a conical shape. A suction fan 16 is fixedly connected to the top of the guide cover 15, and the suction end of the suction fan 16 is set downward.

[0039] In this embodiment: By setting up an L-shaped rod 13 and a protective box 14, the L-shaped rod 13 serves to connect the fixing ring 7 and the protective box 14, providing a stable support structure for the protective box 14. This ensures that the protective box 14 can be firmly installed above the fixing ring 7 and will not loosen or shift due to vibration or other external forces during equipment operation. The protective box 14 can prevent external impurities, dust, etc. from entering the gear transmission system, extending the service life of the first bevel gear 11 and the second bevel gear 12. By setting up a guide cover 15, the special shape of the guide cover 15 can play a good guiding role for the purified gas. When the suction fan 16 is working, the suction fan 16 can draw in the purified air by generating suction and then smoothly discharge it from the treatment tower 3, thereby ensuring the circulation and renewal of the gas in the treatment tower 3 and maintaining the continuous and stable operation of the entire phenol recovery and separation process.

[0040] Working principle: First, a mixed gas containing phenol is introduced from the left side of the bottom of the treatment tower. When the phenol-containing gas passes through the honeycomb structured packing body 4, the absorbent in the absorbent storage tank 53 is drawn out by the centrifugal pump 52 through the first extraction pipe 54 and evenly sprayed onto the honeycomb structured packing body 4 through the conduit 51, rotary joint 61, metal pipe 62, connecting pipe 63 and water outlet pipe 65 to absorb and separate the phenol in the mixed gas. The purified gas is guided by the guide cover 15 at the top of the treatment tower 3 and discharged from the treatment tower 3 by the suction fan 16. When it is necessary to clean the honeycomb structured packing body 4, the controller 2 controls the reversing valve 57 to extract the absorbent from the absorbent storage tank 53. The switching between drawing cleaning fluid from the cleaning fluid storage tank 55 and the centrifugal pump 52 allows the centrifugal pump 52 to draw cleaning fluid from the cleaning fluid storage tank 55 to clean the honeycomb structured packing body 4. At the same time, the controller 2 starts the drive motor 9, which drives the transmission shaft 10 to rotate. The transmission shaft 10 drives the first bevel gear 11 to rotate through the second bevel gear 12, thereby causing the metal pipe 62 to rotate. The metal pipe 62 drives the connecting pipe 63, the support ring 64, and the water outlet pipe 65 to rotate together, so that the water outlet pipe 65 can evenly spray the absorbent or cleaning fluid onto the honeycomb structured packing body 4, achieving a comprehensive cleaning of the honeycomb structured packing body 4 or ensuring that the absorbent and phenol-containing gas come into full and complete contact.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
