Description

Technical Field

[0001] This utility model belongs to the technical field of flue gas desulfurization exhaust pipe installation, and particularly relates to an easy-to-install flue gas desulfurization exhaust pipe. Background Technology

[0002] Flue gas desulfurization refers to the process of removing sulfur oxides from flue gas or other industrial waste gas. A desulfurization tower is a device used to remove sulfides and particulate matter from waste gas. A desulfurization exhaust pipe is a pipe used to discharge the desulfurized flue gas. In summary, the existing technology has the following problems: The desulfurization tower purifies the flue gas by contacting it with a scrubbing liquid, which absorbs harmful substances such as sulfides from the flue gas. The purified flue gas is then discharged through an exhaust pipe, which is usually bolted to the desulfurization tower. The exhaust pipe is typically in a harsh working environment, such as high temperature, high humidity, and highly corrosive gases. The bolts are prone to corrosion and rust, leading to reduced bolt strength or even breakage. Moreover, the tightening force of the bolts is difficult to control, easily resulting in either too loose or too tight bolts. Therefore, a flue gas desulfurization exhaust pipe that is easy to install is proposed to solve the above problems. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides an easy-to-install flue gas desulfurization exhaust pipe, which has the advantage of making the exhaust pipe used in the desulfurization tower easy to install. It solves the problem that existing desulfurization towers purify flue gas by contacting the flue gas with a scrubbing liquid, which absorbs harmful substances such as sulfides in the flue gas. The purified flue gas is then discharged through the exhaust pipe. The exhaust pipe is usually installed in the desulfurization tower with bolts. The desulfurization tower exhaust pipe is usually in a harsh working environment, such as high temperature, high humidity, and strong corrosive gases. The bolts are prone to corrosion and rust, which leads to reduced bolt strength or even breakage. Moreover, the tightening force of the bolts is difficult to control, and it is easy to produce problems of being too loose or too tight.

[0004] This utility model is implemented as follows: a flue gas desulfurization exhaust pipe that is easy to install includes a desulfurization tower and an installation pipe. The top of the desulfurization tower and the bottom of the installation pipe are fixedly connected. The top of the installation pipe is movably connected to the exhaust pipe. An installation groove is opened inside the installation pipe. An installation shell that mates with the installation groove is fixedly connected to the surface of the exhaust pipe. The surface of the installation shell is movably connected to the inner cavity of the installation groove. A control ring frame is movably connected to the inner cavity of the installation shell. The top of the control ring frame penetrates through the installation shell and extends to the outside of the inner cavity of the installation shell. An installation assembly is provided in the inner cavity of the installation shell.

[0005] In a preferred embodiment of this invention, the mounting assembly includes four mounting plates. The mounting plates, on the side furthest from the flue pipe, penetrate the mounting shell and extend to the outer side of the inner cavity of the mounting shell. Two limiting sliders are fixedly connected to the surface of each mounting plate. Eight limiting slide frames, which cooperate with the limiting sliders, are fixedly connected to the inner cavity of the mounting shell. The surfaces of the limiting sliders are movably connected to the inner cavities of the limiting slide frames. A spring is fixedly connected to the surface of each mounting plate, and the surface of the spring is fixedly connected to the inner cavity of the mounting shell. By providing the mounting assembly, when the flue pipe needs to be installed in the desulfurization tower, the mounting assembly restricts the position of the flue pipe.

[0006] In a preferred embodiment of this utility model, a mating frame is fixedly connected to the top of the mounting plate, and four mating rotating frames that mate with the mating frame are movably connected to the inner cavity of the mounting shell via a rotating shaft. The inner cavity of the mating rotating frame is movably connected to the surface of the mating frame, and the bottom of the control ring frame is in contact with the surface of the mating rotating frame. By setting the mating frame and the mating rotating frame, when the mating rotating frame rotates, it can generate a squeezing force on the mating frame, and the mating frame subjected to the squeezing force can drive the mounting plate to move.

[0007] As a preferred embodiment of this utility model, the top of the mounting shell is fixedly connected to two positioning folding plates, and the surface of the control ring frame is provided with two folding plate holes that cooperate with the positioning folding plates. The surface of the positioning folding plate is movably connected to the inner cavity of the folding plate hole. By setting the positioning folding plate and the folding plate hole, when the control ring frame moves, it will drive the folding plate hole to move along the surface of the positioning folding plate. The cooperation between the folding plate hole and the positioning folding plate has a limiting effect on the movement position of the control ring frame.

[0008] As a preferred embodiment of this utility model, four positioning plates are fixedly connected to the surface of the mounting shell, and four positioning shells that cooperate with the positioning plates are fixedly connected to the top of the mounting tube. The surface of the positioning plate is in contact with the inner cavity of the positioning shell. By setting the positioning plate and the positioning shell, when the positioning plate moves to the inner cavity of the positioning shell, the mounting shell will move to a fixed position in the inner cavity of the mounting groove, thereby ensuring that the mounting plate can be accurately inserted into the inner cavity of the plate groove.

[0009] As a preferred embodiment of this utility model, the inner cavity of the mounting groove on the surface of the mounting shell is provided with four plate slots that cooperate with the mounting fixing plate. The surface of the mounting fixing plate contacts the inner cavity of the plate slot. By setting the plate slots, when the mounting shell moves into the inner cavity of the mounting groove, the control ring frame is released, and the restoring force generated by the spring returning to its shape will drive the mounting fixing plate to be inserted into the inner cavity of the plate slot. The cooperation between the mounting fixing plate and the plate slot has a limiting effect on the position of the mounting shell.

[0010] As a preferred embodiment of this utility model, a sealing ring is fixedly connected to the surface of the mounting shell, and a sealing ring groove is formed on the surface of the mounting tube to cooperate with the sealing ring. The surface of the sealing ring is in close contact with the inner cavity of the sealing ring groove. By setting the sealing ring and the sealing ring groove, when the mounting shell moves to the inner cavity of the mounting groove, the sealing ring will move into the inner cavity of the sealing ring groove. The cooperation between the sealing ring and the sealing ring groove increases the sealing performance of the connection between the exhaust pipe and the mounting tube.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model solves the problem of existing desulfurization towers purifying flue gas by using a combination of installation components, installation fixing plates, limit sliders, limit sliding frames, and springs. These components work by bringing flue gas into contact with scrubbing liquid, which absorbs harmful substances such as sulfides from the flue gas. The purified flue gas is then discharged through an exhaust pipe, which is typically bolted to the desulfurization tower. The exhaust pipe is usually in a harsh working environment, such as high temperature, high humidity, and highly corrosive gases. The bolts are prone to corrosion and rust, leading to reduced bolt strength or even breakage. Furthermore, the tightening force of the bolts is difficult to control, easily resulting in either excessive looseness or excessive tightness.

[0013] 2. By setting up an installation component, when the mounting frame moves, it will drive the mounting fixing plate to move into the inner cavity of the mounting shell. At the same time, the mounting fixing plate will drive the limiting slider to move along the inner cavity of the limiting slide frame. The force generated when the mounting fixing plate moves will cause the spring to undergo elastic deformation. The restoring force generated by the spring returning to its shape will drive the mounting fixing plate to be locked into the inner cavity of the plate groove. The installation component has a limiting effect on the position of the exhaust pipe. Attached Figure Description

[0019] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown in the figure, an easy-to-install flue gas desulfurization exhaust pipe provided by this utility model embodiment includes a desulfurization tower 1 and an installation pipe 2. The top of the desulfurization tower 1 and the bottom of the installation pipe 2 are fixedly connected. An exhaust pipe 3 is movably connected to the top of the installation pipe 2. An installation groove 4 is opened inside the installation pipe 2. An installation shell 5 that cooperates with the installation groove 4 is fixedly connected to the surface of the exhaust pipe 3. The surface of the installation shell 5 is movably connected to the inner cavity of the installation groove 4. A control ring frame 6 is movably connected to the inner cavity of the installation shell 5. The top of the control ring frame 6 passes through the installation shell 5 and extends to the outside of the inner cavity of the installation shell 5. An installation component 7 is provided in the inner cavity of the installation shell 5.

[0022] refer to Figure 4 The mounting assembly 7 includes four mounting plates 701. The side of the mounting plate 701 away from the exhaust pipe 3 passes through the mounting shell 5 and extends to the outer side of the inner cavity of the mounting shell 5. Two limiting sliders 702 are fixedly connected to the surface of the mounting plate 701. Eight limiting slide frames 703 that cooperate with the limiting sliders 702 are fixedly connected to the inner cavity of the mounting shell 5. The surface of the limiting sliders 702 is movably connected to the inner cavity of the limiting slide frames 703. A spring 704 is fixedly connected to the surface of the mounting plate 701. The surface of the spring 704 is fixedly connected to the inner cavity of the mounting shell 5.

[0023] The above solution is adopted: by setting the installation component 7, when the flue pipe 3 needs to be installed on the desulfurization tower 1, the installation component 7 has a restrictive effect on the position of the flue pipe 3.

[0024] refer to Figure 4 The top of the mounting plate 701 is fixedly connected to a mating frame 8. The inner cavity of the mounting shell 5 is movably connected to four mating rotating frames 9 that mate with the mating frame 8 via a rotating shaft. The inner cavity of the mating rotating frame 9 is movably connected to the surface of the mating frame 8. The bottom of the control ring frame 6 is in contact with the surface of the mating rotating frame 9.

[0025] The above scheme is adopted: by setting the mating frame 8 and the mating rotating frame 9, when the mating rotating frame 9 rotates, it can generate a squeezing force on the mating frame 8, and the mating frame 8 subjected to the squeezing force can drive the mounting plate 701 to move.

[0026] refer to Figure 2 Two positioning folding plates 10 are fixedly connected to the top of the mounting shell 5. Two folding plate holes 11 are opened on the surface of the control ring frame 6 to cooperate with the positioning folding plates 10. The surface of the positioning folding plate 10 is movably connected to the inner cavity of the folding plate hole 11.

[0027] The above scheme is adopted: by setting the positioning baffle 10 and the baffle hole 11, when the control ring frame 6 moves, it will drive the baffle hole 11 to move along the surface of the positioning baffle 10. The cooperation between the baffle hole 11 and the positioning baffle 10 has a limiting effect on the movement position of the control ring frame 6.

[0028] refer to Figure 2 Four positioning plates 12 are fixedly connected to the surface of the mounting shell 5, and four positioning shells 13 that cooperate with the positioning plates 12 are fixedly connected to the top of the mounting tube 2. The surface of the positioning plate 12 is in contact with the inner cavity of the positioning shell 13.

[0029] The above solution is adopted: by setting the positioning plate 12 and the positioning shell 13, when the positioning plate 12 moves to the inner cavity of the positioning shell 13, the mounting round shell 5 will move to the fixed position in the inner cavity of the mounting round groove 4, thereby ensuring that the mounting fixing plate 701 can be accurately inserted into the inner cavity of the plate groove 14.

[0030] refer to Figure 2 The inner cavity of the mounting groove 4 on the surface of the mounting shell 5 is provided with four plate grooves 14 that are used in conjunction with the mounting fixing plate 701. The surface of the mounting fixing plate 701 is in contact with the inner cavity of the plate groove 14.

[0031] The above solution is adopted: by setting the plate groove 14, when the mounting shell 5 moves into the inner cavity of the mounting groove 4, the control ring frame 6 is released, and the restoring force generated by the spring 704 returning to its shape will drive the mounting fixing plate 701 to be inserted into the inner cavity of the plate groove 14. The cooperation between the mounting fixing plate 701 and the plate groove 14 has a limiting effect on the position of the mounting shell 5.

[0032] refer to Figure 2 and Figure 3 A sealing ring 15 is fixedly connected to the surface of the mounting shell 5. A sealing ring groove 16 is opened on the surface of the mounting tube 2 to cooperate with the sealing ring 15. The surface of the sealing ring 15 is in close contact with the inner cavity of the sealing ring groove 16.

[0033] The above solution is adopted: by setting the sealing ring 15 and the sealing ring groove 16, when the mounting shell 5 moves into the inner cavity of the mounting groove 4, the sealing ring 15 will move into the inner cavity of the sealing ring groove 16. The cooperation of the sealing ring 15 and the sealing ring groove 16 increases the sealing performance of the connection between the exhaust pipe 3 and the mounting pipe 2.

[0034] The working principle of this utility model:

[0035] When using the desulfurization tower 1, if the exhaust pipe 3 needs to be installed conveniently, the user first presses the control ring frame 6 at the bottom. When the control ring frame 6 moves, it will drive the folding plate hole 11 to move along the surface of the positioning folding plate 10. When the control ring frame 6 moves, it will exert a squeezing force on the mating rotating frame 9. The mating rotating frame 9 under the squeezing force will rotate along the surface of the mating frame 8 through the rotating shaft. The rotational force of the mating rotating frame 9 on the mating frame 8 will drive the mating frame 8 to move closer to the exhaust pipe 3. When the mating frame 8 moves, it will drive the mounting fixing plate 701 to move into the inner cavity of the mounting shell 5. At the same time, the mounting fixing plate 701 will drive the limiting slider 702 to move along the inner cavity of the limiting slider frame 703. Furthermore, the force generated when the mounting plate 701 moves will cause the spring 704 to undergo elastic deformation. When the mounting plate 701 is completely moved into the inner cavity of the mounting shell 5, the positioning plate 12 will be moved into the inner cavity of the positioning shell 13. At the same time, the mounting shell 5 will move into the inner cavity of the mounting groove 4, and the sealing ring 15 will move into the inner cavity of the sealing ring groove 16. After that, the control ring frame 6 is released, and the restoring force generated by the spring 704 returning to its shape will drive the mounting plate 701 to be inserted into the inner cavity of the plate groove 14. The cooperation of the mounting plate 701 and the plate groove 14 has a restrictive effect on the position of the mounting shell 5 and the flue pipe 3. At this time, the flue pipe 3 used by the desulfurization tower 1 needs to be installed conveniently.

[0036] In summary, this easy-to-install flue gas desulfurization exhaust pipe, through the coordinated use of installation components 7, installation fixing plate 701, limit slider 702, limit sliding frame 703, and spring 704, solves the problem of existing desulfurization towers purifying flue gas by contacting it with scrubbing liquid, which absorbs harmful substances such as sulfides from the flue gas. The purified flue gas is then discharged through the exhaust pipe. The exhaust pipe is usually bolted to the desulfurization tower. The desulfurization tower exhaust pipe is usually in a harsh working environment, such as high temperature, high humidity, and strong corrosive gases. The bolts are prone to corrosion and rust, leading to reduced bolt strength or even breakage. Moreover, the bolt tightening force is difficult to control, easily resulting in excessively loose or tight bolts.
