[0002] The airflow distribution guide plate in the calcined black adsorption purification tower is a key component used in the calcined black adsorption purification tower. It is mainly used to optimize the airflow distribution in the tower to improve the adsorption and purification effect of the tower. The guide plate will make the airflow flow along a predetermined path to avoid uneven phenomena such as short circuit, deflection or eddies.

[0003] However, cleaning the deflector is tedious and time-consuming due to its high position. Utility Model Content

[0004] The purpose of this utility model is to provide a uniform airflow guide plate for the adsorption and purification tower of the roasted black method, so as to solve the problem mentioned in the background art that the guide plate is too high, making cleaning cumbersome and time-consuming.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a uniform airflow guide plate for a roasting black adsorption purification tower, comprising a fixed cylinder and multiple guide plate bodies installed inside the fixed cylinder;

[0006] The fixed cylinder is provided with a fixed collar inside. The fixed collar has nozzles on its circular inner wall and on the upper and lower sides of the guide plate body.

[0007] Preferably, a diversion pipe b is fixedly connected between the outer walls of the right ends of the two nozzles to guide water flow into the nozzles, and a diversion pipe a is fixedly connected to the outer walls of the right ends of the plurality of diversion pipes b to guide water flow into the diversion pipe b.

[0008] Preferably, a guide pipe is fixedly connected between the rear outer walls of the plurality of diversion pipes a to guide water flow into the diversion pipe a, and an inlet is provided inside the right outer wall of the guide pipe to connect with an external water source.

[0009] Preferably, a cover plate is provided on one side of each of the plurality of nozzles to cover the nozzles, and a fixed shaft is provided between the plurality of cover plates and the nozzles to limit the flipping angle and the position of the flipping center of the cover plates.

[0010] Preferably, each of the circular inner walls of the plurality of diverter pipes b is fixedly connected with a retaining ring, and each of the plurality of retaining rings and the cover plate is fixedly connected with a spring to limit the maximum flip angle of the cover plate.

[0011] Preferably, the maximum flip angle of the cover plate is 60 degrees, and the two adjacent cover plates are symmetrical.

[0012] Preferably, a fixing frame a is fixedly connected to the front outer wall of the fixing cylinder, and a fixing frame b is fixedly connected to the rear outer wall of the fixing cylinder.

[0013] Preferably, fixing holes are provided inside the four corners of the front outer wall of the fixing frame a and the fixing frame b, and the main bodies of the multiple guide plates are all inclined.

[0014] Compared with the prior art, this utility model provides an airflow uniform distribution guide plate for a roasted black adsorption purification tower, which has the following beneficial effects:

[0015] 1. By installing nozzles, guide pipes, and diversion pipes a and b, when cleaning the main body of the guide plate is required, an external water source can be turned on. The external water source enters the interior of diversion pipe a through the guide pipe, and is then guided into diversion pipe b. It is then sprayed out through two nozzles connected to the end of diversion pipe b. The water flow will spray onto the upper and lower surfaces of the main body of the guide plate, ensuring that both the central area and the edge of the main body of the guide plate are fully covered by the water flow. This avoids situations where some areas are not cleaned properly, ensuring consistent cleaning results. Cleaning personnel can complete the cleaning by operating the water source switch on the ground, greatly simplifying the operation process, saving a lot of time and labor costs, and reducing the safety risks associated with working at height.

[0016] 2. By installing a fixing ring, fixing shaft, cover plate, and spring, when the water flow is guided through the diversion pipe b, it will pass through the fixing ring and push the cover plate. Under the restriction of the fixing shaft, the cover plate will flip over, blocking the nozzle. The cover plate can block larger impurities and prevent them from entering the nozzle and causing blockage. At the same time, when the cover plate flips over, it will drive the spring to stretch, limiting the maximum flip angle of the cover plate. This allows the water flow to be accurately sprayed onto the main body of the guide plate under the guidance of the cover plate, so that the water flow can be more concentrated on the parts of the guide plate that need to be cleaned, effectively improving cleaning efficiency and avoiding water waste.

[0022] 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.

[0023] This utility model provides, for example Figure 1-4 The diagram illustrates an airflow distribution guide plate for a roasting black adsorption purification tower. It includes a fixed cylinder 3 and multiple guide plate bodies 1 installed inside the fixed cylinder 3. Roasting flue gas containing pollutants enters the fixed cylinder 3 through the inlet of the purification tower. Before entering the fixed cylinder 3, the airflow has an uneven velocity distribution and flow direction. The airflow entering the fixed cylinder 3 encounters multiple guide plate bodies 1. The guide plate bodies 1, based on their shape and angle, guide and divert the airflow. After being evenly distributed by the guide plate bodies 1, the airflow enters the next area with a more uniform velocity and flow direction.

[0024] The fixed cylinder 3 is equipped with a fixed collar 7. The fixed collar 7 has nozzles 8 on its circular inner wall and on both the upper and lower sides of the guide plate body 1. When it is detected that the surface of the guide plate body 1 has accumulated pollutants to a certain extent and cleaning is required, the airflow channel of the purification tower is first closed to prevent water and impurities from entering the adsorbent area or affecting the normal operation of the purification tower. The external water source is then turned on, and water is transported to the fixed collar 7 through the pipeline. The fixed collar 7 distributes the water evenly to the nozzles 8 on the upper and lower sides of the guide plate body 1. The nozzles 8 spray water onto the upper and lower surfaces of the guide plate body 1. The water flow impacts the surface of the guide plate body 1 with a certain pressure and angle, washing off the attached pollutants. The washed-off water is discharged through a designated location inside the tower. After cleaning, the guide plate body 1 is allowed to dry.

[0025] like Figure 3 and Figure 4As shown, a diversion pipe b11 is fixedly connected between the outer walls of the right ends of the two nozzles 8 to guide water flow into the nozzles 8. A diversion pipe a10 is fixedly connected to the outer walls of the right ends of multiple diversion pipes b11 to guide water flow into the diversion pipes b11. A guide pipe 9 is fixedly connected between the outer walls of the rear ends of multiple diversion pipes a10 to guide water flow into the diversion pipes a10. An inlet 6 is provided inside the outer wall of the right end of the guide pipe 9 to connect with an external water source.

[0026] Open the external water source valve so that the water flows into the guide pipe 9 through the inlet 6 and flows to multiple branch pipes a10 at a certain flow rate and pressure. The branch pipes a10 evenly distribute the water flow from the guide pipe 9 to each branch pipe b11. The branch pipes b11 further guide the water flow precisely to the two nozzles 8 connected to them.

[0027] like Figure 3 and Figure 4 As shown, a cover plate 14 is provided on one side of each of the multiple nozzles 8 to cover the nozzles 8. A fixed shaft 13 is provided between the multiple cover plates 14 and the nozzles 8 to limit the flipping angle and the position of the flipping center of the cover plate 14. A fixed ring 12 is fixedly connected to the circular inner wall of each of the multiple diversion pipes b11. A spring 15 is fixedly connected between the multiple fixed rings 12 and the cover plate 14 to limit the maximum flipping angle of the cover plate 14. The maximum flipping angle of the cover plate 14 is sixty degrees. The two adjacent cover plates 14 are symmetrical.

[0028] When the water flow reaches the diversion pipe b11 and impacts the cover plate 14, the impact force of the water flow gradually increases and overcomes the resistance of the spring 15. The cover plate 14 begins to rotate around the fixed axis 13. As the cover plate 14 rotates, the water flow is guided by the cover plate 14 and sprayed out from the nozzle 8 at a specific angle, accurately spraying the surface of the guide plate body 1. Due to the symmetrical structure between adjacent cover plates 14, the spray angle and distribution of the water flow at different positions are relatively uniform, thereby cleaning the guide plate body 1 thoroughly and evenly.

[0029] like Figure 1 As shown, a fixed frame a2 is fixedly connected to the front outer wall of the fixed cylinder 3, and a fixed frame b4 is fixedly connected to the rear outer wall of the fixed cylinder 3. Fixed holes 5 are opened inside the four corners of the front outer walls of the fixed frames a2 and b4, and the main bodies 1 of the multiple guide plates are all inclined.

[0030] Using the fixing hole 5, initially position the fixing frame a2 and fixing frame b4 to the support structure of the purification tower, insert bolts through the fixing hole 5, and tighten them with nuts to stably install the fixing cylinder 3.

[0031] The implementation principle of this embodiment is as follows: Roasting flue gas containing pollutants enters the fixed cylinder 3 through the inlet of the purification tower. Before entering the fixed cylinder 3, the airflow has an uneven velocity distribution and flow direction. The airflow entering the fixed cylinder 3 encounters multiple guide plate bodies 1. The guide plate bodies 1 guide and divert the airflow according to their shape and angle. After passing through the evenly distributed airflow of the guide plate bodies 1, the airflow enters the next area with a more uniform velocity and flow direction. When it is detected that pollutants have accumulated to a certain extent on the surface of the guide plate bodies 1 and cleaning is required, the airflow channel of the purification tower is first closed to prevent water and impurities from entering the adsorbent area or affecting the normal operation of the purification tower during the cleaning process. Then, an external water source is turned on, and water is transported through a pipe to the inside of the fixed collar 7. The fixed collar 7 evenly distributes the water to the nozzles 8 located on the upper and lower sides of the guide plate bodies 1. The nozzles 8 spray water onto the upper and lower surfaces of the guide plate bodies 1. The water flow impacts the surface of the guide plate bodies 1 with a certain pressure and angle, washing off the attached pollutants. The washed-off water is discharged through a designated location inside the tower. After cleaning, the guide plate bodies 1 are allowed to dry.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
