Description

Technical Field

[0001] This utility model relates to the field of spray mechanism technology, and in particular to a spray assembly for a flue gas desulfurization tower. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] A desulfurization tower is a device used for treating industrial waste gas, containing components such as spraying and mist collection. Flue gas desulfurization often employs the calcium-based desulfurization process. The slurry is pumped into the spray pipes via a circulating pump, atomized into fine droplets from the nozzles, and evenly dispersed in all directions, fully contacting and reacting with the upward-moving flue gas to remove sulfur dioxide. The spray nozzles are prone to clogging after a period of use, requiring maintenance. However, existing spray pipes are typically a single, integrated structure, requiring workers to completely remove the entire pipe from the desulfurization tower for maintenance, a time-consuming and labor-intensive process that limits its usability. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned shortcomings by providing a flue gas desulfurization tower spray assembly that enables efficient and convenient maintenance of the spray assembly.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a flue gas desulfurization tower spray assembly, comprising,

[0006] An installation ring is installed on the inner wall of the desulfurization tower, and a strip-shaped installation plate is provided at the bottom of the installation ring;

[0007] A conveying component, which is disposed on the mounting plate;

[0008] Multiple assembly frames arranged in a ring within an installation ring have conveying cavities inside that communicate with a conveying component. The conveying component is used to receive the spray liquid and divert the spray liquid into the conveying cavities of each assembly frame.

[0009] Multiple spray pipes are detachably mounted on each of the assembly frames. When the spray pipes are installed on the assembly frames, they are interconnected with the corresponding conveying chambers. The spray pipes are used to access the desulfurization liquid in the corresponding conveying chambers and spray it out.

[0010] Furthermore, the conveying component includes a diversion assembly and a liquid inlet assembly. The diversion assembly is rotatably mounted on the mounting plate and located at the center of the mounting ring. The liquid inlet assembly is rotatably mounted on the diversion assembly. The diversion assembly and the liquid inlet assembly are dynamically sealed together. The liquid inlet assembly is connected to an external spray liquid source and is used to receive the spray liquid and inject the spray liquid into the diversion assembly. The diversion assembly is used to divert the spray liquid into each assembly frame. A locking assembly is provided on the diversion assembly to limit the relative position of the diversion assembly and the mounting plate.

[0011] Furthermore, the liquid inlet assembly includes an annular and hollow liquid inlet container, with an injection head communicating with its interior on the liquid inlet container. The injection head is connected to an external spray liquid source. The diversion assembly includes a rotatable liquid inlet platform mounted on a mounting plate. The liquid inlet platform has a conduction cavity inside, and its side wall has an inlet and an outlet communicating with the interior of the conduction cavity. The inlet communicates with the liquid inlet container and is used to guide the spray liquid in the liquid inlet container into the conduction cavity. The outlet communicates with the assembly frame and is used to guide the spray liquid in the conduction cavity into the assembly frame.

[0012] The mounting plate has a polygonal locking groove located at the bottom of the center of the liquid inlet platform. The locking assembly includes a push rod located at the center of the liquid inlet platform with its telescopic end facing downward. The moving end of the push rod is provided with a locking block that matches the locking groove. The corresponding locking block of the liquid inlet platform is offset from the conduction cavity. The push rod drives the locking block to descend and insert into the locking groove to lock the liquid inlet platform so that it cannot rotate.

[0013] Furthermore, the assembly frame includes a frame body horizontally arranged on the liquid inlet platform. The conveying chamber is opened in the frame body. The frame body has a first connector and a second connector, both communicating with the conveying chamber, on its sides near and away from the liquid inlet platform. The first connector is connected to the corresponding liquid outlet via a hose, and the second connector is connected to the corresponding spray pipe via a hose. A limiting frame is also provided on the side of the frame body near the liquid inlet platform. The limiting frame has an inclined surface, which is used to guide the spray pipe to be inserted between the limiting frame and the frame body, and to limit one side of the spray pipe when the spray pipe is parallel to the frame body. A spring pin is slidably provided on the side of the frame body away from the liquid inlet platform. The spring pin is used to limit the spray pipe on the side away from the limiting frame. A bearing strip is provided on the frame body. The length of the bearing strip is not less than the length of the spray pipe. The bearing strip is offset from the spraying end of the spray pipe and can support the spray pipe.

[0014] Furthermore, the spray pipe includes a horizontally arranged pipe body and a plurality of nozzles installed at the bottom of the pipe body along the pipe body's direction. The pipe body is connected to each of the nozzles. A connector is provided on the side wall of the pipe body. The connector and the second connector are detachably connected through a flexible hose, and a sealing layer is provided at the connection between the connector and the flexible hose.

[0015] The beneficial effects of this utility model are reflected in:

[0016] In this invention, the conveying component is connected to an external spray liquid source and pumped to the corresponding conveying chamber of each assembly frame via a pump body. The spray liquid then enters the spray pipe and is sprayed out for spray desulfurization treatment of flue gas. When maintenance of the corresponding spray pipe is required, the operator only needs to remove the corresponding spray pipe from the assembly frame. This method is simple and quick to operate, and does not require all the spray pipes to be removed from the spray tower, which is convenient for practical use. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figure 1-5 This utility model discloses a flue gas desulfurization tower spray assembly, including an installation ring 1, which is installed on the inner wall of the desulfurization tower. A strip-shaped installation plate 2 is installed at the bottom of the installation ring 1. A conveying component is provided on the installation plate 2, which is located at the center of the installation ring 1. Multiple assembly frames 5 are arranged in a ring within the installation ring 1. The assembly frame 5 includes a frame body 51 and a conveying cavity 52 opened inside the frame body 51. The conveying cavity 52 is connected to the conveying component.

[0026] In one embodiment, the conveying component is used to receive the spray liquid and divert the spray liquid into the conveying cavity 52 of each assembly frame 5. Each assembly frame 5 is detachably provided with a spray pipe 6. When the spray pipe 6 is installed on the assembly frame 5, it will communicate with the corresponding conveying cavity 52. ​​The spray pipe 6 is used to receive the desulfurization liquid in the corresponding conveying cavity 52 and spray it out.

[0027] In practice, the conveying components are connected to an external spray liquid source and pumped to the corresponding conveying chamber 52 of each assembly frame 5 via a pump body. The spray liquid then enters the spray pipe 6 and is sprayed out to spray desulfurize the flue gas. When the corresponding spray pipe 6 needs to be maintained, the staff only needs to remove the corresponding spray pipe 6 from the assembly frame 5. This method is simple and quick to operate, and it is not necessary to remove all the spray pipes 6 from the spray tower for practical use.

[0028] In practice, pressure sensors can be installed on each spray pipe 6. The pressure sensors are used to detect pressure changes inside the spray pipe 6. When a spray pipe 6 becomes blocked, its internal pressure changes, which can alert the staff and make it easier for them to accurately identify which spray pipe 6 is blocked. This allows the staff to perform maintenance in a targeted manner and improves maintenance efficiency. Since pressure sensors are common knowledge in this field, their specific structure and working principle will not be described in detail in this article.

[0029] In one embodiment, the conveying component includes a diversion assembly 3 and a liquid inlet assembly 4. The diversion assembly 3 is rotatably mounted on the mounting plate 2 and is located at the center of the mounting ring 1. The liquid inlet assembly 4 is rotatably mounted on the diversion assembly 3. The diversion assembly 3 and the liquid inlet assembly 4 are dynamically sealed together. A locking assembly is provided on the diversion assembly 3 to limit the relative position of the diversion assembly 3 and the mounting plate 2. An annular groove 7 is provided on the inner wall of the mounting ring 1. Rolling balls are rolled on each assembly frame 5 and the rolling balls are in contact with the corresponding annular groove 7 of the mounting ring 1.

[0030] In practice, the liquid inlet component 4 can be connected to the external spray liquid source via a rigid pipe. It is used to inlet the spray liquid and inject it into the diversion component 3. The diversion component 3 is used to divert the spray liquid into each assembly frame 5. When in use, the diversion component 3 can be connected to an external power source, such as a temporary motor or other equipment. This power source is used to drive the diversion component 3 to rotate around the center of the mounting ring 1 when the locking component does not limit the diversion component 3. During this process, since the liquid inlet component 4 and the diversion component 3 are rotatably connected and dynamically sealed, the liquid inlet component 4 can remain stationary and stably deliver liquid into the diversion component 3. Each assembly frame 5 moves synchronously with the diversion component 3, and the rolling balls on each assembly frame 5 also move at the corresponding annular groove 7 of the mounting ring 1. This makes the structure stable during rotation, and the staff can disassemble the spray pipes 6 on different assembly frames 5 from a fixed position, thereby improving the safety and convenience of maintenance.

[0031] In one embodiment, the liquid inlet assembly 4 includes an annular and hollow liquid inlet container 41, on which an injection head 42 communicating with the interior is installed. The injection head 42 is connected to an external spray liquid source. The diversion assembly 3 includes a rotatable liquid inlet platform 31 mounted on the mounting plate 2, and the liquid inlet container 41 is rotatably connected to the liquid inlet platform 31. A conduction cavity is opened inside the liquid inlet platform 31. An inlet port 32 and an outlet port 33 communicating with the interior of the conduction cavity are opened on the side wall of the liquid inlet platform 31. The inlet port 32 is connected to the liquid inlet container 41 and is used to guide the spray liquid in the liquid inlet container 41 into the conduction cavity. The outlet port 33 is connected to the assembly frame 5 and is used to guide the spray liquid in the conduction cavity into the assembly frame 5.

[0032] With this design, the spray liquid inside the liquid inlet container 41 passes through the liquid inlet 32 ​​and enters the conduction chamber. The spray liquid in the conduction chamber then enters the assembly frame 5 through the liquid outlet 33, thereby completing the liquid transport and conduction.

[0033] In one embodiment, the plate 21 of the mounting plate 2 is provided with a polygonal locking groove 22. The locking groove 22 is located at the bottom of the center of the liquid inlet platform 31. The locking assembly includes a push rod 34 located at the center of the liquid inlet platform 31 with its telescopic end facing downward. The moving end of the push rod 34 is equipped with a locking block 35 that is adapted to the locking groove 22. The corresponding locking block 35 of the liquid inlet platform 31 is offset from the conduction cavity. The push rod 34 drives the locking block 35 to descend and insert into the locking groove 22 to lock the liquid inlet platform 31 so that it cannot rotate.

[0034] In practice, when the liquid inlet platform 31 needs to rotate, the locking block 35 is moved up and down by the push rod 34 and is not inserted into the locking groove 22. In this state, the liquid inlet platform 31 can be rotated and adjusted by an external power source. Conversely, when the liquid inlet platform 31 needs to remain stationary, the locking block 35 is pulled down by the push rod 34 and slid into the locking groove 22. At this time, the liquid inlet platform 31 is fixed on the plate 21 and cannot rotate. The push rod 34 can be an electric push rod, and its telescopic end can be controlled to extend and retract after being powered on.

[0035] It should be noted that the assembly frame 5 includes a frame body 51 horizontally mounted on the liquid inlet platform 31, and a delivery chamber 52 is opened inside the frame body 51. A first connector 53 and a second connector 55, both communicating with the delivery chamber 52, are respectively installed on the sides of the frame body 51 near and away from the liquid inlet platform 31. The first connector 53 is connected to the corresponding liquid outlet 33 via a hose, and the second connector 55 is connected to the corresponding spray pipe 6 via a hose. A limit frame 54 is also installed on the side of the frame body 51 near the liquid inlet platform 31. The limit frame 54 has an inclined... The inclined surface is used to guide the spray pipe 6 into the space between the limiting frame 54 and the frame body 51, and to limit one side of the spray pipe 6 when the spray pipe 6 and the frame body 51 are kept parallel. A spring pin 56 is slidably installed on the side of the frame body 51 away from the liquid inlet platform 31. The spring pin 56 is used to limit the side of the spray pipe 6 away from the limiting frame 54. A support bar 57 is installed on the frame body 51. The length of the support bar 57 is not less than the length of the spray pipe 6. The support bar 57 is offset from the spray end of the spray pipe 6 and can support the spray pipe 6.

[0036] In practice, the limiting bracket 54 and the spring pin 56 abut against the top of both sides of the spray pipe 6, while the bearing strip 57 contacts the bottom of the spray pipe 6, thus ensuring the stability of the spray pipe 6 after installation. The spring pin 56 consists of a spring and an L-plate connected to the spring. The L-plate is slidably installed inside the frame 51, and its vertical part extends outside the frame 51 for operator access. The end of the spring away from the L-plate contacts the inner wall of the frame 51. During use, the operator disconnects the hose connecting the spray pipe 6 to the second connector 55, and then pushes the L-plate towards the side closer to the spring. The L-plate releases the restriction on the side of the spray pipe 6 away from the limit frame 54. Then, the spray pipe 6, after being released from the restriction on one side, is rotated in the inclined direction of the inclined surface of the limit frame 54. The spray pipe 6 can then be removed from under the limit frame 54. This method only requires the operator to operate on the side of the spray pipe 6 near the spring pin 56. The operator does not need to move the position. In actual situations, a maintenance hole can be opened at the corresponding position on the spray tower. The operator can easily disassemble and maintain different spray pipes 6 by using the power source to drive the diversion component 3 to rotate at the maintenance hole.

[0037] In one embodiment, the spray pipe 6 includes a horizontally arranged pipe body 61 and a plurality of nozzles 62 installed at the bottom of the pipe body 61 along the direction of the pipe body 61. The pipe body 61 is connected to each nozzle 62. A connector 63 is installed on the side wall of the pipe body 61. The connector 63 is detachably connected to the second connector 55 through a hose, and a sealing layer is installed at the connection between the connector 63 and the hose. The sealing layer can be a silicone layer.

[0038] This design can further improve the sealing ability of the connection through the sealing layer. The connection between the hose and the connector 63 and the second connector 55 can be installed with a threaded sleeve. In use, the hose is rotated to make the threaded sleeve rotate together, and then it can be removed from the connection between the connector 63 and the second connector 55. The threaded sleeve is common knowledge in the field, so its specific structure and working principle will not be described in detail in this article.

If the specific posture changes, the directional indicators will also change accordingly.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.
