Description

Technical Field

[0001] This utility model belongs to the technical field of desulfurization equipment, and specifically relates to a dry flue gas desulfurization equipment. Background Technology

[0002] Dry flue gas desulfurization is a technology that removes sulfur dioxide from flue gas emitted by coal-fired and oil-fired boilers, industrial furnaces, etc., without using liquid absorbent slurry or solution. Its main difference from wet desulfurization and semi-dry desulfurization is that the material remains in a dry or near-dry state throughout the desulfurization process, and the product is also a dry powder.

[0003] In existing technologies, activated carbon is generally used to adsorb sulfides in flue gas. As a result, the activated carbon plates need to be replaced or cleaned frequently during use. However, activated carbon plates are generally installed with bolts, which can easily loosen during frequent disassembly and assembly, thus reducing the stability of the activated carbon plates during use. Utility Model Content

[0004] To address the issue that activated carbon adsorbs sulfides in flue gas, requiring frequent replacement or cleaning of the activated carbon plates during use, and that these plates are typically installed with bolts which can loosen with frequent disassembly and reassembly, thus reducing the stability of the activated carbon plates during use, this invention proposes a dry flue gas desulfurization device to overcome the aforementioned technical problems in existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a dry flue gas desulfurization device, comprising a shell:

[0007] The housing is equipped with an adsorption component, a driving component, a transmission component, a snap-fit ​​component, and a limiting component.

[0008] An adsorption component, the outer surface of which is fixedly connected to the inner wall of the housing, so that the adsorption component can adsorb sulfides in the flue gas inside the housing;

[0009] A drive assembly whose surface is engaged with the top end of a transmission assembly, so that the drive assembly drives the transmission assembly to move.

[0010] The bottom end of the snap-fit ​​component is fixedly connected to the top end of the transmission component, and the outer surface of the snap-fit ​​component is snap-fitted with the inside of the adsorption component, so that when the transmission component moves, it drives the snap-fit ​​component to snap and limit the adsorption component.

[0011] The limiting component has its outer surface slidingly disposed with the interior of the driving component, so that the limiting component restricts the position of the driving component.

[0012] Furthermore, the adsorption component includes a mounting frame, the outer surface of which is fixedly connected to the inner wall of the housing, and an installation groove is provided inside the mounting frame, with an activated carbon plate slidably disposed inside the installation groove.

[0013] Furthermore, the drive assembly includes a mounting bracket, one side of which is fixedly connected to one side of the housing. A drive shaft is rotatably mounted inside the mounting bracket, a drive gear is fixedly mounted on the outer surface of the drive shaft, and a drive rod is fixedly mounted on one end of the drive shaft.

[0014] Furthermore, the transmission assembly includes a limiting strip, one side of which is fixedly connected to one side of the housing. A rack is slidably provided on the outer surface of the limiting strip, the top end of which meshes with the surface of the transmission gear, and a connecting bracket is fixedly installed at the bottom end of the rack.

[0015] Furthermore, the snap-fit ​​assembly includes snap-fit ​​grooves, which are respectively opened inside the mounting frame and the activated carbon plate. A snap-fit ​​rod is slidably arranged inside the snap-fit ​​groove, and the bottom end of the snap-fit ​​rod is fixedly connected to the top end of the connecting frame.

[0016] The snap-fit ​​rod has a sliding limit block inside, and one side of the limit block is fixedly connected to one side of the housing.

[0017] Furthermore, the limiting assembly includes a limiting bolt, one end of which is fixedly connected to one side of the housing, and a connecting cylinder is threadedly connected to the threaded surface of the limiting bolt, with the outer surface of the connecting cylinder slidingly disposed with the interior of the drive rod.

[0018] Furthermore, a support foot is fixedly connected to the bottom of the housing, and a mounting hole is provided at the top of the support foot.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model separates itself by rotating the limiting component, and then rotating the limiting component drives the driving component with rotating outer surface to rotate. This causes the driving component to move the transmission component with surface engagement. Since the top end of the transmission component is fixedly connected to the bottom end of the snap-fit ​​component, and the outer surface of the snap-fit ​​component is snap-fitted with the inside of the adsorption component, when the transmission component moves, it can drive the snap-fit ​​component to release the snap-fit ​​limitation on the adsorption component. This makes it easy to remove the adsorption component from the inside of the housing. Then, the cleaned or replaced adsorption component is reinserted into the housing, and the above steps are reversed to complete the replacement of the adsorption component. The process is convenient and can prevent the adsorption component from loosening during use, thereby improving the stability of the adsorption component during use.

[0021] 2. When the rack and pinion drives the connecting frame to move, it can also move the locking rod fixed at the top. When the locking rod moves, it can move along the direction of the internally sliding limit block. Since the outer surface of the locking rod slides with the inside of the locking groove, and the locking groove is opened inside the mounting frame and the activated carbon plate, when the locking rod moves, it can pass through the inside of the locking groove opened inside the mounting frame and the activated carbon plate in one go. This allows the locking rod to cooperate with the locking groove to lock and limit the activated carbon plate, thereby improving the efficiency of the installation and removal of the activated carbon plate.

[0022] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0033] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0034] Please see Figures 1-6 As shown, this utility model is a dry flue gas desulfurization device, including a shell 1:

[0035] The housing 1 is respectively provided with an adsorption component 2, a driving component 3, a transmission component 4, a snap-fit ​​component 5, and a limiting component 6;

[0036] The adsorption component 2 has its outer surface fixedly connected to the inner wall of the housing 1 so that the adsorption component 2 adsorbs sulfides in the flue gas inside the housing 1.

[0037] The drive assembly 3 has its surface engaged with the top end of the transmission assembly 4, so that the drive assembly 3 drives the transmission assembly 4 to move.

[0038] The bottom end of the snap-fit ​​component 5 is fixedly connected to the top end of the transmission component 4, and the outer surface of the snap-fit ​​component 5 is snap-fitted with the inside of the adsorption component 2, so that when the transmission component 4 moves, it drives the snap-fit ​​component 5 to snap-fit ​​and limit the adsorption component 2.

[0039] The limiting component 6 has its outer surface slidingly disposed with the interior of the driving component 3 so that the limiting component 6 restricts the position of the driving component 3.

[0040] In use, one end of the housing 1 is installed with the flue gas discharge end containing sulfides, allowing the flue gas to enter the interior of the housing 1. As the flue gas passes through the interior of the adsorption component 2, the adsorption component 2 adsorbs the sulfides in the flue gas. When the adsorption component 2 needs to be replaced or cleaned, the limiting component 6 is rotated to separate itself. Then, rotating the limiting component 6 drives the drive component 3, which is rotated on its outer surface, to rotate. This causes the drive component 3 to move the transmission component 4, which is engaged with the surface. Since the top end of the transmission component 4 is fixedly connected to the bottom end of the locking component 5, and the outer surface of the locking component 5 is engaged with the interior of the adsorption component 2, when the transmission component 4 moves, it can cause the locking component 5 to release the locking limit on the adsorption component 2, making it easy to remove the adsorption component 2 from the interior of the housing 1. Then, the cleaned or replaced adsorption component 2 is reinserted into the interior of the housing 1, and the above steps are reversed to complete the replacement of the adsorption component 2, which is quite convenient.

[0041] This invention separates itself by rotating the limiting component 6, and then rotating the limiting component 6 drives the driving component 3, which is rotated on its outer surface, to rotate. This causes the driving component 3 to move the transmission component 4, which is engaged with the surface, during operation. Since the top end of the transmission component 4 is fixedly connected to the bottom end of the locking component 5, and the outer surface of the locking component 5 is engaged with the inside of the adsorption component 2, when the transmission component 4 moves, it can cause the locking component 5 to release the locking limit on the adsorption component 2. This makes it easy to remove the adsorption component 2 from the inside of the housing 1. Then, the cleaned or replaced adsorption component 2 can be reinserted into the inside of the housing 1, and the above steps can be reversed to complete the replacement of the adsorption component 2. The process is convenient and can prevent the adsorption component 2 from loosening during use, thereby improving the stability of the adsorption component 2 during use.

[0042] In one embodiment, the adsorption component 2 includes a mounting frame 201, the outer surface of which is fixedly connected to the inner wall of the housing 1, and a mounting groove 202 is provided inside the mounting frame 201, with an activated carbon plate 203 slidably disposed inside the mounting groove 202.

[0043] Since there are two sets of mounting frames 201 and activated carbon plates 203 arranged symmetrically, the activated carbon plates 203 can perform multi-stage adsorption of sulfides contained in the flue gas entering the housing 1, thereby improving the desulfurization effect during the use of the dry flue gas desulfurization device.

[0044] In one embodiment, the drive assembly 3 includes a mounting bracket 301, one side of which is fixedly connected to one side of the housing 1. A drive shaft 302 is rotatably mounted inside the mounting bracket 301. A drive gear 303 is fixedly mounted on the outer surface of the drive shaft 302. A drive rod 304 is fixedly mounted on one end of the drive shaft 302.

[0045] By rotating one end of the drive rod 304, the drive shaft 302 mounted on the other end is rotated. Since the outer surface of the drive shaft 302 is rotatably connected to the interior of the mounting bracket 301, and the outer surface of the drive shaft 302 is fixedly installed to the interior of the transmission gear 303, when the drive shaft 302 rotates, it can drive the transmission gear 303 to rotate around the interior of the mounting bracket 301, thereby improving the stability of the transmission gear 303 during rotation.

[0046] In one embodiment, the transmission component 4 includes a limiting strip 401, one side of which is fixedly connected to one side of the housing 1. A rack 402 is slidably disposed on the outer surface of the limiting strip 401. The top end of the rack 402 meshes with the surface of the transmission gear 303. A connecting bracket 403 is fixedly installed at the bottom end of the rack 402.

[0047] When the transmission gear 303 rotates along with the transmission shaft 302, it can drive the rack 402, which is meshed with the surface, to move. Since the inside of the rack 402 is slidably disposed with the outer surface of the limiting strip 401, and one side of the limiting strip 401 is fixedly connected to one side of the housing 1, when the rack 402 moves, it can move along the direction of the limiting strip 401, and the rack 402 can drive the connecting frame 403 mounted at the bottom end to move along the direction of the limiting strip 401, thereby improving the stability of the connecting frame 403 during the movement process.

[0048] In one embodiment, the snap-fit ​​assembly 5 includes a snap-fit ​​groove 501, which is respectively opened inside the mounting frame 201 and the activated carbon plate 203. A snap-fit ​​rod 502 is slidably arranged inside the snap-fit ​​groove 501, and the bottom end of the snap-fit ​​rod 502 is fixedly connected to the top end of the connecting frame 403.

[0049] A limiting block 503 is slidably provided inside the snap-fit ​​rod 502, and one side of the limiting block 503 is fixedly connected to one side of the housing 1.

[0050] When the connecting frame 403 moves along with the rack 402, it can drive the locking rod 502 fixed at the top to move. When the locking rod 502 moves, it can move along the direction of the internally sliding limit block 503. Since the outer surface of the locking rod 502 is slidably disposed with the inside of the locking groove 501, and the locking groove 501 is opened inside the mounting frame 201 and the activated carbon plate 203, when the locking rod 502 moves, it can pass through the inside of the locking groove 501 opened inside the mounting frame 201 and the activated carbon plate 203 in one go. This allows the locking rod 502 to cooperate with the locking groove 501 to lock and limit the activated carbon plate 203, thereby improving the efficiency of the installation and removal of the activated carbon plate 203.

[0051] In one embodiment, the limiting component 6 includes a limiting bolt 601, one end of which is fixedly connected to one side of the housing 1. The threaded surface of the limiting bolt 601 is threadedly connected to a connecting cylinder 602, and the outer surface of the connecting cylinder 602 is slidably disposed with the interior of the drive rod 304.

[0052] By rotating the connecting cylinder 602, its internal threads move along the outer surface of the limiting bolt 601, thereby releasing the threaded connection between the connecting cylinder 602 and the limiting bolt 601. This allows the connecting cylinder 602 to drive the drive rod 304, which is rotatably mounted on its outer surface, to rotate. Since the connecting cylinder 602 and the drive rod 304 are perpendicularly positioned, the drive rod 304 can rotate with the pushing force of the connecting cylinder 602. Furthermore, when the connecting cylinder 602 is threadedly mounted with the limiting bolt 601, the connecting cylinder 602 can restrict the position of the drive rod 304, thereby improving the stability of the flue gas dry desulfurization device during operation.

[0053] In one embodiment, for the housing 1, a support foot 7 is fixedly connected to the bottom end of the housing 1, and a mounting hole 8 is provided at the top end of the support foot 7.

[0054] The support feet 7 are provided to support the housing 1, and the mounting holes 8 are provided to install the support feet 7 to the ground, thereby improving the stability of the housing 1 during use.

[0055] Through the above technical solution, 1. By rotating the limiting component 6, it separates itself, and then rotating the limiting component 6 drives the driving component 3, which is rotated on the outer surface, to rotate. This causes the driving component 3 to drive the transmission component 4, which is engaged on the surface, to move. Since the top end of the transmission component 4 is fixedly connected to the bottom end of the snap-fit ​​component 5, and the outer surface of the snap-fit ​​component 5 is snap-fitted with the inside of the adsorption component 2, when the transmission component 4 moves, it can drive the snap-fit ​​component 5 to release the snap-fit ​​limitation on the adsorption component 2, thus making it easy to remove the adsorption component 2 from the inside of the housing 1. Then, the cleaned or replaced adsorption component 2 is reinserted into the inside of the housing 1, and the above steps are reversed to complete the replacement of the adsorption component 2. The process is relatively convenient and can prevent the adsorption component 2 from loosening during use, thereby improving the stability of the adsorption component 2 during use.

[0056] 2. When the rack 402 drives the connecting frame 403 to move, it can drive the locking rod 502 fixed at the top to move. When the locking rod 502 moves, it can move along the direction of the internally sliding limit block 503. Since the outer surface of the locking rod 502 is slidably set with the inside of the locking groove 501, and the locking groove 501 is opened inside the mounting frame 201 and the activated carbon plate 203, when the locking rod 502 moves, it can pass through the inside of the locking groove 501 opened inside the mounting frame 201 and the activated carbon plate 203 in one go. This allows the locking rod 502 to cooperate with the locking groove 501 to lock and limit the activated carbon plate 203, thereby improving the efficiency of the installation and removal of the activated carbon plate 203.
