Description

Technical Field

[0001] This invention relates to the field of desulfurizing agent storage technology, and in particular to a desulfurizing agent storage device for wastewater treatment. Background Technology

[0002] Currently, in the process of wastewater treatment in power plants, a large amount of sulfur-containing gases are generated due to high temperatures. These gases are mainly hydrogen sulfide and sulfur dioxide. The most common treatment method is dry desulfurization, which uses a desulfurizing agent to catalytically adsorb hydrogen sulfide, converting it into elemental sulfur and storing it within the catalyst. However, existing desulfurizing agents face storage problems. Existing desulfurizing agent storage devices lack corresponding ventilation systems, leading to heat accumulation and decomposition of the desulfurizing agent, rendering it ineffective. However, prolonged exposure to ventilated storage devices can oxidize the desulfurizing agent, resulting in a loss of its effectiveness. Summary of the Invention

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0029] Example 1

[0030] Reference Figures 1-3This is the first embodiment of the present invention. This embodiment provides a desulfurizing agent storage device for wastewater treatment, which includes a rotating assembly 100, including a support pile 101, a first sleeve 102 disposed on the outer wall of the support pile 101, a horn groove 102a disposed on the outer wall of the first sleeve 102, and a second sleeve 103 disposed on the outer wall of the first sleeve 102.

[0031] The flipping assembly 200 includes a storage tank 201 disposed on the outer wall of the second sleeve 103, a piston block 202 disposed inside the storage tank 201, a blocking plate 203 disposed inside the storage tank 201, a feed inlet disposed on the end face of the blocking plate 203, and a rotating component 204 disposed on the outer wall of the storage tank 201. In this design, the support pile 101 is cylindrical, and the first sleeve 102 is fixedly sleeved on the outer wall of the support pile 101. The outer wall of the first sleeve 102 is provided with arrayed horn grooves 102a. The second sleeve 103 is rotatably sleeved on the outer wall of the first sleeve 102, and the second sleeve 103 can rotate along the outer wall of the first sleeve 102 without moving up or down.

[0032] The array of storage tanks 201 is mounted on the outer surface of the second sleeve 103, and the rotating part 204 on the outer wall of the storage tank 201 can pass through the second sleeve 103 and rotate along the inner wall of the horn groove 102a. When the second sleeve 103 rotates, the rotating part 204 slides along the inner wall of the horn groove 102a, thereby enabling the storage tank 201 to rotate when the second sleeve 103 rotates. This allows the desulfurizing agent inside the storage tank 201 to slide, loosen the internal desulfurizing agent, and replace the air inside the desulfurizing agent, thereby removing heat. The heat is then carried away through the heat conduction of the outer wall of the storage tank 201. At the same time, in order to better achieve internal air control and internal sealing, a piston block 202 is installed inside the storage tank 201. The piston block 202 in this solution is made of soft rubber and can adaptively fill gaps when compressed. The blocking plate 203 can... The blocking plate 203 slides along the outer wall of the piston block 202. A feed inlet is fixedly connected to the upper surface of the blocking plate 203. The blocking plate 203 is a circular plate with a channel at its center that has the same radius as the piston block 202. The radius of its feed inlet is larger than the radius of the piston block 202. When the blocking plate 203 moves downward past the bottom of the piston block 202, the desulfurizing agent begins to be added into the storage tank 201 through the channel in the center of the blocking plate 203. When a certain amount is stored, the blocking plate 203 can be moved up and down to compact the desulfurizing agent inside, reducing the air inside the desulfurizing agent. Subsequently, the blocking plate 203 begins to slide along the outer wall of the piston block 202, and the interior begins to seal. As the blocking plate 203 continues to move upward, the total amount of air inside remains unchanged, but the volume of the storage tank 201 increases, and the internal air concentration decreases, reducing the environmental impact on the storage of the desulfurizing agent.

[0033] In summary, when desulfurizing agent needs to be stored, push the blocking plate 203 along the piston block 202 to the bottom of the piston block 202, and then add desulfurizing agent through the feed port. When a certain amount is added, push the blocking plate 203 up and down to compact the internal desulfurizing agent. Then move the blocking plate 203 upward along the outer wall of the piston block 202 to reduce the internal air concentration. If it is necessary to periodically treat the internal temperature of the desulfurizing agent, rotate the second sleeve 103. The rotating part 204 on the outer wall of the storage tank 201 rotates along the inside of the horn groove 102a, causing the storage tank 201 to rotate, thus inverting the storage tank 201. The desulfurizing agent will continuously scatter on the surface of the blocking plate 203. The air originally between the desulfurizing agent and the blocking plate 203 begins to flow from the inside of the desulfurizing agent to the top, thereby causing a temperature change inside the desulfurizing agent and preventing internal heat accumulation. If the desulfurizing agent needs to be used, open the blocking plate 203 to remove the internal desulfurizing agent.

[0034] Example 2

[0035] Reference Figures 1-3 This is the second embodiment of the present invention, which differs from the first embodiment in that: the desulfurizing agent storage device for wastewater treatment in the previous embodiment further includes a first receiving tank 101a inside the support pile 101;

[0036] The horn groove 102a on the outer wall of the first sleeve 102 includes a vertical groove 102a-1 on the outer wall of the first sleeve 102, and a horn mouth 102a-2 connected to the end of the vertical groove 102a-1; the outer wall of the second sleeve 103 is provided with a first movable channel 103a.

[0037] In this embodiment, the horn groove 102a penetrates the first sleeve 102, and the horn groove 102a on the outer wall of the first sleeve is divided into two parts: a vertical groove 102a-1 and a horn opening 102a-2 at the lower end of the vertical groove 102a-1. The horn opening 102a-2 has an "eight" structure. The rotating component 204 will first enter from one side of the horn opening 102a-2, and then enter the vertical groove 102a-1 to change direction. The first movable channel 103a penetrates the second sleeve 103, connecting the inside and outside of the second sleeve 103. The rotating component 204 passes through the first movable channel 103a, and the storage tank 201 is connected to the first sleeve 102 by means of the rotating component 204.

[0038] The inner wall of the first sleeve 102 is provided with a first connecting rod 104, one end of the first connecting rod 104 is provided with a guide block 105, and the outer wall of the guide block 105 is provided with a first inclined surface 105a.

[0039] The first sleeve 102 is fixedly connected to the first connecting rod 104 above the horn groove 102a. The guide block 105 is fixedly installed below the first connecting rod 104. The guide block 105 is below the horn opening 102a-2, and the upper surface of the guide block 105 is provided with a first inclined surface 105a. The first inclined surface 105a is parallel to the horn opening 102a-2, and a through groove is formed between the first inclined surface 105a and the horn opening 102a-2.

[0040] It should be noted that the guide block 105 is located below the horn opening 102a-2, and its left and right ends are longer than the ends of the horn opening 102a-2, so as to better guide the rotating part 204 into the horn groove 102a.

[0041] A motor 106 is installed inside the first receiving groove 101a, and the output shaft of the motor 106 is connected to the second sleeve 103.

[0042] The first receiving groove 101a is located on the upper surface of the support pile 101. A motor 106 is fixedly installed inside the groove. The output shaft of the motor 106 passes through the first sleeve 102 and is fixedly connected to the second sleeve 103. When the motor 106 starts, it drives the second sleeve 103 to rotate. Then the rotating part 204 rotates and begins to slide along the first inclined surface 105a, entering the vertical groove 102a-1. Then it rotates and moves along another first inclined surface 105a, causing the storage tank 201 to flip.

[0043] Furthermore, the rotating component 204 includes a second connecting rod 204a on the outer wall of the storage tank 201, and a crossbar 204b connected to the other end of the second connecting rod 204a. Both ends of the crossbar 204b are provided with sliding columns 204c.

[0044] The rotating component 204 includes a second connecting rod 204a. One end of the second connecting rod 204a is detachably connected to the storage tank 201, and the other end is fixedly connected to a crossbar 204b, forming a "T" structure. Both ends of the crossbar 204b are fixedly connected to sliding columns 204c. When the second sleeve 103 rotates, one of the sliding columns 204c slides along the surface of the first inclined plane 105a and then enters the vertical groove 102a-1. At this time, the storage tank 201 rotates 90 degrees. Then, the other sliding column 204c slides along another first inclined plane 105a, continuing to drive the storage tank 201 to rotate and rotate another 90 degrees, thereby realizing the rotation of the storage tank 201.

[0045] In summary, when the second sleeve 103 rotates, the sliding column 204c on the outer wall of the storage tank 201 slides along the first inclined surface 105a and then enters the vertical groove 102a-1. Another sliding column 204c enters another first inclined surface 105a, causing the storage tank 201 to rotate, realizing the flow of the desulfurizing agent inside, realizing the air exchange inside the desulfurizing agent, and ensuring that the internal heat accumulation will not affect the overall storage.

[0046] Example 3

[0047] Reference Figures 1-6 This is the third embodiment of the present invention, which differs from the previous two embodiments in that: the inner wall of the storage tank 201 is provided with a first sliding groove 201a, and the inner wall of the first sliding groove 201a is provided with a collar 205; the inner wall of the storage tank 201 is provided with a first sliding groove 201b.

[0048] In this embodiment, the inner wall of the storage tank 201 has a first sliding groove 201a with a radius at one end larger than the inner diameter of the storage tank 201. In this embodiment, the collar 205 is fixed to the inner wall of the first sliding groove 201a, and the collar 205 has a notch in the middle suitable for the sliding of the feed inlet.

[0049] The piston block 202 has an arc surface 202a on its end face;

[0050] The blocking plate 203 has a second inclined surface 203a on one surface and a third inclined surface 203b on the other surface.

[0051] The upper surface of the piston block 202 is an arc surface 202a, which mainly serves to facilitate the flow of desulfurizing agent along the arc surface to the third inclined surface 203b, and then along the third inclined surface 203b into the storage tank 201, reducing the accumulation of desulfurizing agent at the feed inlet. Subsequently, the second inclined surface 203a is on the lower surface of the blockage plate 203, which facilitates the pouring out of the desulfurizing agent.

[0052] The piston block 202 has a bearing 206 on the surface away from the arc surface 202a. The storage tank 201 has a support rod 207 inside. Both ends of the support rod 207 have bearings 206, and one bearing 206 is connected to the piston block 202, while the other bearing 206 is connected to the bottom of the storage tank 201. The outer wall of the support rod 207 has a spiral array of stirring rods 207a.

[0053] A bearing 206 is fixedly installed below the piston block 202. A support rod 207 is fixedly connected to the inner wall of the bearing 206. The bearing 206 is sleeved on the outer wall of the other end of the support rod 207. The outer wall of the bearing 206 is fixed to the storage tank 201, which allows the support rod 207 to rotate. Multiple stirring rods 207a are arrayed on the outer wall of the support rod 207. When the desulfurizing agent enters the storage tank 201, it can make the desulfurizing agent accumulate evenly. When it reaches a certain height, it stops rotating and then moves the blocking plate 203 up and down to compact the desulfurizing agent. At the same time, when the air inside the desulfurizing agent is replaced, the desulfurizing agent will fall, and the stirring rods 207a can loosen the compacted desulfurizing agent, making the internal air replacement smoother.

[0054] Furthermore, the surface of the collar 205 is provided with a first elastic element 208, and the other end of the first elastic element 208 is connected to the blocking plate 203.

[0055] The first elastic element 208 is a compression spring. When the blocking plate 203 moves downward, it pulls the first elastic element 208. When the movement ends, the first elastic element 208 pulls the blocking plate 203 back to its original position, thereby increasing the internal space and reducing the internal air concentration.

[0056] The outer wall of the support rod 207 is fitted with a lifting component 209. The lifting component 209 includes a disc 209a on the outer wall of the support rod 207. The outer wall of the disc 209a is provided with a slider 209a-1 that can slide along the inside of the first sliding groove 201b. A second elastic component 209b is provided between the disc 209a and the bottom of the storage tank 201.

[0057] The disc 209a is slidably mounted on the outer wall of the support rod 207. This design uses a keyway sliding connection. When the disc 209a rotates, it drives the support rod 207 to rotate, thus enabling the disc 209a to slide along the outer wall of the support rod 207 and drive the support rod 207 to rotate. Simultaneously, the first groove 201b is an arc-shaped groove with an upward spiral. When the desulfurizing agent falls onto the surface of the disc 209a inside the storage tank 201, as the amount of desulfurizing agent increases, the gravity increases, causing the disc 209a to move downwards, simultaneously driving the support rod 207 to rotate. Rotating rod 207 enables stirring rod 207a to uniformly store the desulfurizing agent. Secondly, a second elastic element 209b, a compression spring, is provided between the disc 209a and the bottom of the storage tank 201. When the storage tank 201 is flipped, the desulfurizing agent is inverted. At this time, there is no gravity acting on the surface of the disc 209a, and the second elastic element 209b begins to push the disc 209a towards the collar 205. Simultaneously, it drives the rotation of support rod 207. At this time, stirring rod 207a will stir and compact the desulfurizing agent, making the internal air exchange more uniform.

[0058] In summary, when the desulfurizing agent has been stored for a certain period of time, the motor 106 is turned on to drive the second sleeve 103 to rotate. Subsequently, the rotating part 204 on the outer wall of the storage tank 201 rotates along the inside of the horn groove 102a, driving the storage tank 201 to rotate, thereby realizing the heat exchange during the storage process. This effectively solves the problem of poor ventilation and lack of ventilation for a long time.
