Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment equipment, in particular to a series-type multi-stage waste gas tower. Background Art

[0002] A tandem multi-stage exhaust tower is a type of exhaust gas purification equipment that uses multiple, different levels of exhaust gas purification units to remove harmful substances from exhaust gas. This equipment is usually composed of multiple exhaust gas purification towers, each equipped with a different exhaust gas purification technology, such as adsorption, catalysis, and photocatalysis. The advantage of a tandem multi-stage exhaust tower is that it can effectively purify a variety of pollutants in exhaust gas and can also process large amounts of exhaust gas.

[0003] For the series-type multi-stage exhaust tower, each tower body has two layers of spherical fillers. Multi-faceted hollow plastic spherical fillers are the most commonly used type of exhaust tower. The spherical fillers are evenly filled on the mesh plate, and the gas and liquid contact and react at the spherical fillers.

[0004] When the exhaust tower has been working for a long time, the spherical fillers need to be replaced. The current replacement method is that workers use a ladder to lean against the exhaust tower, then climb to the maintenance window, open the maintenance window, enter the tower through the maintenance window, and then shovel out the spherical fillers and send them out through the maintenance window. After shoveling out, the spherical fillers are replaced with new ones.

[0005] The above-mentioned packing replacement operation is time-consuming, labor-intensive, and dangerous at height. At the same time, the workload of replacing the series exhaust tower will increase exponentially.

[0041] Example 1

[0042] In order to solve the technical problems in the background technology, the following series multi-stage exhaust tower is provided:

[0043] Combine Figures 1-11 As shown, the serial multi-stage exhaust tower provided by the present invention includes a tower body 1, and multiple tower bodies 1 are sequentially connected in series; the interior of the tower body 1 is sequentially arranged with a first spray rack 12, a support assembly 2, a second spray rack 13 and a second filler support cover 9a from top to bottom; the outer wall of the tower body 1 is sequentially arranged with a first inspection window 11, a second inspection window 14 and a third inspection window 15 from top to bottom; the first inspection window 11 is located between the first spray rack 12 and the support assembly 2, the second inspection window 14 is located between the second spray rack 13 and the second filler support cover 9a, and the third inspection window 15 is located below the second filler support cover 9a; a material guide main 3 is provided at the inner center line of the tower body 1; through the serial tower bodies 1, the tower body 1 can be subjected to multi-stage treatment, so that the discharged exhaust gas can meet the demand; through the multiple vertical inspection windows, it is convenient for workers to inspect the filler and the spray rack;

[0044] The support assembly 2 includes a support plate 21 and a first filler support cover 22. The support plate 21 is fixed to the outer wall of the material guide main pipe 3. The center of the first filler support cover 22 is slidably mounted on the outer wall of the material guide main pipe 3. The surface of the first filler support cover 22 is connected to the traction assembly 5. The first filler support cover 22 is placed above the support plate 21. The center of the second filler support cover 9a is fixed to the outer wall of the material guide main pipe 3. The tops of the first filler support cover 22 and the second filler support cover 9a are filled with spherical fillers 6.

[0045] The top of the material guide main pipe 3 is an open structure, and the opening structure is a first material inlet 31. The first material inlet 31 is located above the first stuffing support cover 22. The top of the first material inlet 31 is cooperatively embedded with a first material inlet blocking component 4. The side wall of the material guide main pipe 3 is provided with a second material inlet 32. The second material inlet 32 ​​is located above the second stuffing support cover 9a. The outside of the second material inlet 32 ​​is blocked by the second material inlet blocking component 8. The bottom end of the material guide main pipe 3 extends downward and outward from the second stuffing support cover 9a. The outlet of the material guide main pipe 3 points to the third inspection window 15.

[0046] like Figure 2 、 Figure 3 、 Figure 7 As shown, in the flue gas treatment stage, the first feed port blocking component 4 blocks the first feed port 31, and the second feed port blocking component 8 blocks the second feed port 32, and the flue gas passes through each tower body 1 connected in series in sequence;

[0047] like Figure 9 and Figure 11 As shown, in the filler cleaning stage, the traction component 5 drives the first filler support cover 22 to move upward, the first filler support cover 22 pushes up to open the first material port sealing component 4, and pulls to open the second material port sealing component 8, the first material port sealing component 4 and the second material port sealing component 8 are opened, the spherical filler 6 in the first filler support cover 22 enters the material guide main pipe 3 through the first feed port 31, the spherical filler 6 in the second filler support cover 9a enters the material guide main pipe 3 through the second feed port 32, and the spherical filler 6 flows out through the material guide main pipe 3 to the third inspection window 15.

[0048] The material guide pipe 3 is designed as a hollow structure. It not only serves as the central fixing structure of the first filler support cover 22 and the second filler support cover 9a, but also serves as a guide structure for the filler, directing the inflowing waste filler to the third inspection window 15. In this way, workers can simply lay the material splicing cloth on the ground during inspection, without having to operate at high altitude.

[0049] When the filler is discharged, the first material port sealing component 4 and the second material port sealing component 8 are driven to open by the traction component 5, so that the spherical filler 6 in the first filler holder 22 and the second filler holder 9a automatically flows out to the material guide main pipe 3, realizing the automatic discharge of the spherical filler 6, without the need to shovel out the filler, and the cleaning efficiency is high.

[0050] The traction assembly 5 rotates forward to drive the first filling support cover 22 to move upward, and the opening and closing power of the first material port blocking assembly 4 and the second material port blocking assembly 8 is controlled by the first filling support cover 22, so that the first material port blocking assembly 4 and the second material port blocking assembly 8 are fully opened, and the spherical filling 6 flows into the material guide main pipe 3; then, the traction assembly 5 rotates forward and reverse slightly, and the first filling support cover 22 can move downward slightly under the action of its own gravity and the gravity of the filling; the traction assembly 5 repeats the forward and reverse rotation, driving the first filling support cover 22 to rise and fall, thereby driving the spherical filling 6 to shake, thereby accelerating the outflow speed of the spherical filling 6 and preventing the spherical filling 6 from being blocked at the first feed port 31;

[0051] In this embodiment, the first filling support cover 22 and the second filling support cover 9a have the same structure. The first filling support cover 22 is a mesh funnel structure. A center circular plate 221 with a planar structure is provided at the center of the first filling support cover 22. The shape of the support plate 21 is the same as the bottom shape of the first filling support cover 22. A center horizontal plate 211 is provided at the center of the support plate 21. The material guide main pipe 3 is fixedly passed through the center horizontal plate 211 and slidably passed through the center circular plate 221.

[0052] The first filler support cover 22 and the second filler support cover 9a are designed as funnel structures, which can make the spherical fillers 6 gather and flow downward, making the discharge of the spherical fillers 6 smoother and simpler;

[0053] The supporting plate 21 can support and position the first filler holder 22 so that the first filler holder 22 is stopped on the supporting plate 21 during the filtering stage.

[0054] In this embodiment, the traction assembly 5 includes a traction motor 51 and a traction rope 52. The traction motor 51 is arranged at the top of the outer wall of the tower body 1. The traction wheel of the traction motor 51 is wrapped with the traction rope 52. The traction rope 52 extends along the first spray rack 12 to the center line of the tower body 1 and bends downward to pass through the first spray rack 12. The bottom end of the traction rope 52 is fixedly connected to the center circular plate 221.

[0055] The traction motor 51 can drive the traction wheel to rotate forward and reverse, and then the traction rope 52 can pull the center circular plate 221. The traction force of the traction rope 52 can act on the center of the first stuffing support cover 22, and the first stuffing support cover 22 can stably lift and lower.

[0056] Example 2

[0057] like Figures 1-11 As shown, based on the above embodiment, this embodiment further provides the following content:

[0058] In order to achieve the shaking of the spherical filler 6 in the first filler support cover 22, the traction force of the traction component 5 is applied to the first filler support cover 22 in the first embodiment. In order to achieve the above function without adding a new power source, the first material port blocking component 4 needs to solve the following problems: 1. The opening and closing action can be linked with the action of the first filler support cover 22; 2. When the first filler support cover 22 moves downward, the first material port blocking component 4 can gradually block the first feed port 31; 3. The space occupied should be as small as possible so as not to affect the flue gas treatment stage and the filler treatment stage of the spherical filler 6. To solve the above problems, the following solutions are given:

[0059] In this embodiment, the first material port blocking assembly 4 includes a receiving square tube 41, a spring 42, a movable square tube 43, and a blocking plate 44. The receiving square tube 41 is vertically fixed at the center of the bottom surface of the first spray rack 12, and the bottom end opening of the receiving square tube 41 is slidably embedded with the movable square tube 43. The bottom end of the movable square tube 43 is provided with a blocking plate 44, and a sealing gasket 441 is provided at the center of the bottom surface of the blocking plate 44. The sealing gasket 441 cooperates to contact and block the first material feed port 31. Two push rods 45 are vertically symmetrically provided at the outer edge of the bottom surface of the blocking plate 44. The two push rods 45 are symmetrically located on both sides of the material guide main pipe 3, and the bottom ends of the push rods 45 contact the center circular plate 221; a spring 42 is provided inside the receiving square tube 41, and the spring 42 is located above the movable square tube 43; when the first filler support cover 22 is in contact with the support plate 21, the blocking plate 44 is in contact with and blocks the first material feed port 31.

[0060] When the first stuffing support cover 22 moves upward, the first stuffing support cover 22 pushes the push rod 45, which in turn pushes the sealing plate 44 and the movable square tube 43 to move upward, and the movable square tube 43 enters the receiving square tube 41 and compresses the spring 42, thereby realizing the automatic opening of the first material port sealing assembly 4; the linkage between the first material port sealing assembly 4 and the first stuffing support cover 22 is realized. At the same time, the receiving square tube 41 and the movable square tube 43 are arranged at the center line, occupying a small area, and are linked by two push rods 45 arranged on both sides of the material guide main pipe 3, which is easy to coordinate.

[0061] In this embodiment, the side wall of the blocking plate 44 is provided with a guide ring 442 for the traction rope 52 to pass through, and a shielding mesh cover 46 is connected to the outer edge of the upper surface of the blocking plate 44, and the top of the shielding mesh cover 46 is fixedly connected to the bottom side of the storage square tube 41.

[0062] The guide ring 442 can restrain the traction rope 52; the shielding mesh 46 can block the spherical filler 6, preventing the spherical filler 6 from entering the top of the movable square tube 43 and hindering the normal income of the movable square tube 43.

[0063] Since the space of the first feed port 31 is relatively small, the spherical fillers 6 are more likely to aggregate there. To further prevent the first feed port 31 from being blocked, the following solution is provided:

[0064] In this embodiment, a stirring assembly 7 is installed at the inner center line of the receiving square tube 41. The stirring assembly 7 includes a rotating rod 71, which is rotatably installed in the receiving square tube 41. The bottom end of the rotating rod 71 passes through the sealing plate 44 and the protruding part is provided with a stirring blade 72. The top of the rotating rod 71 is provided with horizontally distributed transverse conical teeth 711, and the transverse conical teeth 711 are meshed and connected with the vertical conical teeth 73. The interior of the movable square tube 43 is provided with a through groove 431 for the vertical conical teeth 73 to pass through. The inner wall of the receiving square tube 41 is provided with a vertically extending tooth groove 411, and the part of the vertical conical tooth 73 extending outward from the through groove 431 is meshed and embedded in the tooth groove 411; when the movable square tube 43 moves up and down, the vertical conical teeth 73 mesh and rotate along the tooth groove 411, causing the stirring blade 72 to rotate.

[0065] When the first filler support cover 22 moves up and down, the first material port blocking assembly 4 also moves up and down, the movable square tube 43 retracts and extends, and the vertical cone teeth 73 rotate along the tooth grooves 411, causing the stirring blades 72 to rotate, thereby accelerating the discharge of the spherical filler 6.

[0066] Example 3

[0067] like Figures 1-11 As shown, based on the above embodiment, this embodiment further provides the following content:

[0068] In order to enable the second material port blocking component 8 to achieve the above functions, the second material port blocking component 8 also needs to solve the above three problems of linkage with the first filler support cover 22, self-blocking, and automatic opening and closing. To this end, the present application provides the following solutions:

[0069] In this embodiment, the second material port blocking assembly 8 includes an inner blocking tube 81, an outer blocking tube 82 and a pulling rod 83. The inner blocking tube 81 is fixed to the outer wall of the material guide main pipe 3 and is located above the second material feed port 32. The outer wall of the inner blocking tube 81 is slidably sleeved with the outer blocking tube 82. The outer blocking tube 82 moves downward to block the second material feed port 32. A pulling rod 83 is vertically provided on the top surface of the outer blocking tube 82. The pulling rod 83 slides through the second spray rack 13 and the support plate 21 and the top end is fixedly connected to the bottom surface of the center circular plate 221. The pulling rod 83 is located on both sides of the material guide main pipe 3.

[0070] When the first stuffing support cover 22 moves, it can drive the outer sealing tube 82 to move up and down through the hard traction rod 83 . When the outer sealing tube 82 moves downward, it contacts the second stuffing support cover 9 a to seal the second feed port 32 .

[0071] In this embodiment, the outer wall of the outer sealing tube 82 is provided with a plurality of stirring rods 84 distributed in an annular manner, and the stirring rods 84 are arranged to be inclined upward.

[0072] Since the traction force of the traction rope 52 is limited, the traction rope 52 cannot directly pull the first filler holder 22; therefore, by designing the stirring rod 84 on the side wall of the outer sealing tube 82, the outer sealing tube 82 can move up and down while following the lifting and lowering movement of the first filler holder 22, thereby stirring the spherical filler 6, accelerating the outflow speed of the spherical filler 6, and avoiding blockage.

[0073] Example 4

[0074] like Figures 1-11 As shown, based on the above embodiment, this embodiment further provides the following content:

[0075] Through the above solution, the spherical fillers 6 can be guided to the third inspection window 15, so that workers can perform material receiving operations while standing on the ground. However, if the material guide pipe 3 is directly extended to the third inspection window 15, it will occupy too much space in the third inspection window 15, which will affect the workers' observation of the tower body 1 and the workers will not be able to enter the tower through the third inspection window 15 for maintenance. To solve the above problem, the following solution is provided:

[0076] In this embodiment, the bottom end of the material guide main pipe 3 is connected to an inclined discharge pipe 33 , the discharge pipe 33 is flange-connected to the flexible material guide pipe 9 , and a reserved flange ring 91 is provided at the other end of the flexible material guide pipe 9 away from the discharge pipe 33 .

[0077] In this embodiment, a socket 16 is provided on the inner wall of the tower body 1 . The socket 16 is located above the third inspection window 15 , and a flange ring 91 is reserved to be received and plugged into the socket 16 .

[0078] An inclined discharge pipe 33 is arranged at the outlet of the material guide main pipe 3, and then a flexible material guide pipe 9 is arranged. In this way, when there is no need to clean the filler, the reserved flange ring 91 at the end of the flexible material guide pipe 9 is inserted into the socket 16. In this way, the flexible material guide pipe 9 can be bent and retracted. This storage method, on the one hand, can seal the flexible material guide pipe 9 to prevent smoke from entering from the flexible material guide pipe 9. On the other hand, the completely retracted flexible material guide pipe 9 occupies less space and will not block the third inspection window 15, and will not affect the workers' entry from the third inspection window 15; when the filler needs to be discharged, the reserved flange ring 91 is removed from the socket 16 and then passed through the third inspection window 15.

[0079] The working principle and use process of the present invention:

[0080] In the flue gas treatment stage, the first feed port blocking component 4 blocks the first feed port 31, and the second feed port blocking component 8 blocks the second feed port 32, and the flue gas passes through each tower body 1 connected in series in sequence;

[0081] Filler cleaning stage,

[0082] The first step is to open the discharge port: the traction motor 51 reels the traction rope 52, which drives the first filler holder 22 to slide upward along the material guide pipe 3. The first filler holder 22 contacts the push rod 45, which pushes the blocking plate 44 upward until the first filler holder 22 is flush with the first feed port 31. During this lifting process, the first filler holder 22 drives the outer blocking pipe 82 upward via the traction rod 83, thereby opening the second feed port 32. In this way, the spherical fillers 6 can be discharged through the material guide pipe 3.

[0083] The second step is stirring to prevent blocking: traction drives a small range of forward and reverse rotation, drives the first filler holder 22 to shake up and down, the stirring blade 72 to rotate, and the stirring rod 84 to move up and down, thereby accelerating the outflow speed of the spherical filler 6.
