Therefore, the first activated carbon adsorption plate and the second activated carbon adsorption plate need to be replaced frequently. However, the above patent cannot replace them in time, which seriously affects the performance of the activated carbon and leads to the inability to purify sulfur dioxide. Therefore, a sulfur dioxide filtering device is proposed. Summary of the Utility Model

It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0023] In the following description, numerous specific details are set forth to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] Embodiment 1

[0025] As Figure 1 -4 shows, the present utility model provides a sulfur dioxide filtering device, which includes a filtering box 1. A replacement mechanism 2 is arranged inside the filtering box 1. Conversion mechanisms 3 are arranged at both ends of the replacement mechanism 2. The replacement mechanism 2 includes two groups of telescopic rods 21 and four groups of connecting blocks 29. Four vertical holes 22 are penetrated and opened at the upper end of the filtering box 1. Guide frames 23 are slidably installed inside the four vertical holes 22. Activated carbon adsorption plates 24 are arranged inside the four guide frames 23. Concave seats 25 are arranged at the upper ends of the four activated carbon adsorption plates 24. Elliptical plates 27 are arranged at the upper ends of the four guide frames 23. Connecting rods 210 are fixedly installed at the upper ends of the four concave seats 25 and near the positions of both side edges. The eight connecting rods 210 respectively pass through the upper ends of the four guide frames 23 and are fixed to the lower ends of the four elliptical plates 27. An air outlet box 11 is penetrated and installed at one end of the filtering box 1. An air inlet box 12 is penetrated and installed at the other end of the filtering box 1. The lower ends of the four connecting blocks 29 are respectively fixed to the upper ends of the four guide frames 23. Sealing plates 28 are fixedly installed at the lower ends of the four guide frames 23. The lower ends of the four sealing plates 28 are in contact with the inner bottom end of the filtering box 1. Baffles 26 are welded at the upper ends of the four concave seats 25 and at the positions of both side edges. The upper ends of the eight baffles 26 slide up and down inside the four concave seats 25 respectively. A spraying mechanism 13 is penetrated and installed at the upper end of the air inlet box 12. One ends of the two groups of telescopic rods 21 are respectively fixed to the front and rear ends of the filtering box 1.

[0026] The specific settings and functions of this embodiment will be described in detail below. By providing a replacement mechanism 2, two sets of telescopic rods 21 are activated to operate. The extended ends of the two sets of telescopic rods 21 drive two of the connecting blocks 29 to move upward through the conversion mechanism 3. The two connecting blocks 29 drive the two guiding frames 23 to move upward inside the two vertical holes 22, causing most of the two guiding frames 23 to move out of the inside of the filtration tank 1. Then, the elliptical plate 27 is lifted upward one by one. The elliptical plate 27 drives the concave seat 25 fixed thereto to move upward through the two connecting rods 210, so that the concave seat 25 is removed from the upper end of one of the activated carbon adsorption plates 24. Thus, the activated carbon adsorption plate 24 can be taken out from the inside of the corresponding guiding frame 23. Then, the pre-prepared activated carbon adsorption plate 24 is picked up and placed inside the guiding frame 23. The elliptical plate 27 is pushed downward. The elliptical plate 27 pushes the concave seat 25 to move toward the upper end of the activated carbon adsorption plate 24 through the two connecting rods 210, facilitating the limitation of the activated carbon adsorption plate 24 by the concave seat 25. Therefore, the replacement of the activated carbon adsorption plate 24 can be conveniently carried out, ensuring that the activated carbon in the activated carbon adsorption plate 24 can continue to filter sulfur dioxide and facilitating the continuous purification of sulfur dioxide.

[0027] By providing four sets of activated carbon adsorption plates 24, with two sets as a group, when one group is being replaced, the other group can still continue to purify the sulfur dioxide entering the inside of the filtration tank 1, improving the purification efficiency of sulfur dioxide. And by installing a sealing plate 28 at the lower ends of the four guiding frames 23, when the guiding frames 23 are moved upward, the sealing plate 28 will block the vertical holes 22, preventing the sulfur dioxide inside the filtration tank 1 from flowing out and preventing impact on the environment or the staff. The setting of several baffles 26 can block the gaps between the guiding frames 23 and the activated carbon adsorption plates 24, preventing sulfur dioxide from discharging through the gaps.

[0028] The setting of the spraying mechanism 13. The spraying mechanism 13 is operated to spray the sulfur dioxide entering the air inlet tank 12. Part of the sulfur dioxide gas dissolves in water to produce sulfur dioxide aqueous solution, which flows into the inside of the filtration tank 1. The sulfur dioxide gas that does not dissolve in water directly enters the inside of the filtration tank 1. The aqueous solution of sulfur dioxide and part of the sulfur dioxide gas react with the alkaline solution to produce crystals that accumulate at the bottom of the filtration tank 1.

[0029] Embodiment Two

[0030] Such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown in the figure, the conversion mechanism 3 includes two groups of push seats 31 and four groups of fixed seats 32. One end of each of the four groups of fixed seats 32 is slidably installed with a limit plate 33. One end of each of the two groups of push seats 31 is penetrated and provided with a limit hole 35. The upper ends of the four groups of fixed seats 32 are penetrated and provided with long holes 34. Sliders 36 are slidably installed inside the four long holes 34. The lower ends of the four sliders 36 are respectively fixed to the upper ends of the four limit plates 33. One end of each of the four groups of fixed seats 32 is respectively fixed to one end of the four connecting blocks 29. The lower ends of the two groups of push seats 31 are respectively fixed to the extended ends of the telescopic rods 21.

[0031] The effect achieved by the entire embodiment is that when it is necessary to replace the four activated carbon adsorption plates 24, the conversion mechanism 3 is adjusted according to the activated carbon adsorption plates 24 to be replaced. By moving two of the sliders 36, the two sliders 36 drive the limit plates 33 fixed thereto. The two sliders 36 slide inside the two long holes 34 that cooperate with them respectively, and the two limit plates 33 slide inside the two fixed seats 32 that cooperate with them respectively, so that one end of the two limit plates 33 moves from the inside of the two fixed seats 32 into the two limit holes 35 respectively, thereby completing the cooperation between two of the fixed seats 32 and the two push seats 31, facilitating the removal of two of the activated carbon adsorption plates 24 from the inside of the filter box 1, while the other two activated carbon adsorption plates 24 can continue to purify sulfur dioxide inside the filter box 1.

[0032] Usage method and working principle of this device: First, assemble the air inlet box 12 with the external pipeline for discharging sulfur dioxide. By operating the spraying mechanism 13, sulfur dioxide entering the interior of the air inlet box 12 is sprayed. Part of the sulfur dioxide gas dissolves in water to produce an aqueous sulfur dioxide solution that flows into the interior of the filtration box 1, and the sulfur dioxide gas that does not dissolve in water directly enters the interior of the filtration box 1. The aqueous sulfur dioxide solution and part of the sulfur dioxide gas react with the alkaline solution to produce crystals that accumulate at the bottom of the filtration box 1. The remaining sulfur dioxide is purified by the four groups of activated carbon adsorption plates 24 and discharged through the air outlet box 11. The liquid inside the filtration box 1 is discharged from the reserved water outlet pipe. Then, when it is necessary to replace the activated carbon adsorption plates 24, according to the required activated carbon adsorption plates 24, among the four groups of activated carbon adsorption plates 24, two groups are taken as a set. By moving two of the sliders 36, the two sliders 36 drive the limiting plates 33 fixed thereto. The two sliders 36 slide respectively inside the two elongated holes 34 that cooperate with them, and the two limiting plates 33 slide respectively inside the two fixed seats 32 that cooperate with them, so that one end of the two limiting plates 33 moves from the inside of the two fixed seats 32 into the two limiting holes 35 respectively, thereby completing the cooperation between the two fixed seats 32 and the two pushing seats 31, facilitating the removal of the two activated carbon adsorption plates 24 in one set from the interior of the filtration box 1. Finally, start the operation of the two telescopic rods 21. The extending ends of the two telescopic rods 21 drive two of the connecting blocks 29 to move upward through the conversion mechanism 3. The two connecting blocks 29 drive the two guiding frames 23 to move upward inside the two vertical holes 22, so that most of the two guiding frames 23 are removed from the interior of the filtration box 1. Then, lift the elliptical plate 27 one by one. The elliptical plate 27 drives the concave seat 25 fixed thereto to move upward through the two connecting rods 210, so that the concave seat 25 is removed from the upper end of one of the activated carbon adsorption plates 24, and thus the activated carbon adsorption plate 24 can be taken away from the interior of the guiding frame 23 that cooperates with it. Then, pick up the pre-prepared activated carbon adsorption plate 24 and place it inside the guiding frame 23, and push the elliptical plate 27 downward. The elliptical plate 27 pushes the concave seat 25 to move toward the upper end of the activated carbon adsorption plate 24 through the two connecting rods 210, facilitating the limitation of the activated carbon adsorption plate 24 by the concave seat 25 and enabling the convenient replacement of the activated carbon adsorption plate 24. Repeat the above steps. Insert the other two limiting plates 33 into the limiting holes 35 respectively, and the two activated carbon adsorption plates 24 in the other set can be removed from the interior of the filtration box 1, facilitating their replacement.

[0033] The above are only the preferred embodiments of the present utility model and do not limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as they do not depart from the technical solution content of the present utility model, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
