Description

Technical Field

[0001] This invention relates to the field of tower cleaning tools, specifically a novel tower cleaning tool for a complexed iron desulfurization device. Background Technology

[0002] Unblocking the complexed iron desulfurization unit without stopping production involves using a tower-clearing tool to push against the bottom of the tower during operation to eventually break up the blockage. If this unblocking work is not carried out, the sulfur paste in the tower reagent will not be able to enter the next stage of equipment for further separation. At the same time, as the blockage continues to increase, the tower will eventually become completely ineffective, thus affecting its normal operation. Therefore, it is necessary to use some unblocking tools.

[0003] For example, Chinese patent CN201910696086.9 discloses a cleaning tool for unclogging containers. This tool includes a sleeve that can engage with the clogged container, and a long rod that passes through the sleeve and extends outwards from the sleeve at both ends. The front end of the long rod can extend into the clogged container. A deformation mechanism is connected between the front end of the long rod and the sleeve, allowing it to deform radially with axial displacement. This deformation mechanism is used to clear the blockage inside the container. This solution can effectively unclog containers without emptying them. Of course, this unclogging operation is also applicable to empty containers, offering advantages such as convenience, efficiency, labor-saving, and cost-effectiveness.

[0004] The aforementioned patent provides a cleaning tool for unclogging containers, which can perform cleaning operations without emptying the container. However, existing cleaning tools cause a large amount of chemicals and sulfur paste to fall off the bottom of the tower after unclogging, causing environmental pollution on the ground. At the same time, the fallen chemicals cannot be reused due to contamination, resulting in waste of chemicals and increased chemical usage costs.

[0005] In summary, existing tower clearing technology cannot eliminate the environmental risks and waste caused by chemicals and sulfur paste falling to the ground after the tower bottom is blocked during operation. Therefore, the market urgently needs a tower clearing tool that can eliminate the environmental risks and waste caused by chemicals and sulfur paste falling to the ground after blockage. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0027] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0028] Example 1

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, a novel desulfurization tower clearing tool for a complexed iron desulfurization device includes a sealing mechanism 1. One end of the sealing mechanism 1 has a flange 14 for connecting to the flange at the bottom of the tower. The sealing mechanism 1 also facilitates the installation of all components of the tool. A movable rod 2 is connected to the middle of the sealing mechanism 1, and the movable rod 2 can move up and down along the axis of the sealing mechanism 1. This up-and-down movement of the movable rod 2 can treat blockages at the bottom of the tower. One end of the movable rod 2, inserted into the tower, is equipped with a four-corner drill bit 21, used to break through harder blockages. After the four-corner drill bit 21 is sealed within the sealing mechanism 1, it rotates upwards to break through the sulfur paste blockage. If the blockage is deep, it can be continuously rotated upwards with the movable rod 2 to clear the blockage, depending on the site conditions, until all sulfur paste blockage layers are broken. A locking sleeve joint 3 is provided on the movable rod 2, and the locking sleeve joint 3 is sealed to the bottom end of the sealing mechanism 1.

[0030] like Figure 2 and Figure 3 As shown, the sealing mechanism 1 has an open end and an inner cavity 10 for collecting the liquid medicine during the tower passage process. A drain pipe 11 is located on the side of the sealing mechanism 1, and a drain valve 12 is installed on the drain pipe 11 to discharge the liquid medicine collected inside the cavity 10, enabling the recycling and reuse of the medicine. A handle 13 is located on the side of the drain valve 12 for controlling its opening and closing. The closed end of the sealing mechanism 1 has a threaded hole 17, which facilitates the installation of the locking sleeve 3, making it easy to assemble, disassemble, and use. A sealing groove 18 is located on the outer side of the threaded hole 17 on the outer side of the sealing mechanism 1. The sealing groove 18 facilitates the mating with the locking sleeve 3, allowing for a seal between the locking sleeve 3 and the sealing mechanism 1. Multiple first connecting holes 15 and second connecting holes 16 are evenly distributed on the flange 14, with the first connecting holes 15 and second connecting holes 16 staggered. This structure facilitates the connection of the flange 14 to the tower bottom using bolts.

[0031] like Figure 4 As shown, the end of the moving rod 2 without the four-corner drill bit 21 is provided with a stud 23. The stud 23 facilitates the connection of the moving rod 2 to other components. Furthermore, two first disassembly and assembly platforms 22 are symmetrically provided on the side of the moving rod 2 near the stud 23. The first disassembly and assembly platforms 22 facilitate the use of a wrench to easily disassemble and assemble the moving rod 2.

[0032] like Figure 5As shown, the locking sleeve joint 3 has an adapter ring 33 at one end facing the sealing mechanism 1. The adapter ring 33 is threadedly connected to the threaded hole 17, which facilitates the assembly and disassembly of the locking sleeve joint 3. The sealing sleeve joint has a sealing gasket 32 ​​on the side facing the sealing mechanism 1, and the sealing gasket 32 ​​is aligned with the sealing groove 18. This structure facilitates the sealing gasket 32 ​​to be pressed into the sealing groove to achieve a seal.

[0033] Working Principle: The entire tower clearing tool is installed at the bottom of the tower, and one end of the moving rod 2 with the four-corner drill bit 21 is inserted into the tower. During the operation of the complexed iron desulfurization unit, due to sudden changes in hydrogen sulfide concentration leading to untimely adjustment of the reagents, insufficient air volume and circulation volume, the sulfur slurry content in the reagents continuously increases. Because the diameter of the oxidation tower bottom is much larger than its pipe diameter, the flow rate of the complexed iron solution decreases, and the sulfur slurry deposits at the bottom of the oxidation tower, causing blockage at the tower outlet. At this time, the operator continuously pushes the moving rod 2 upward to break up the sulfur slurry blockage. If the blockage is deep, the moving rod 2 can be continuously rotated upward to clear the blockage according to the site conditions until all the sulfur slurry blockage layers are broken. Compared with the prior art, this invention can carry out tower bottom clearing operations without stopping production, ensuring reduced environmental risks and reagent consumption during the clearing process. With its simple structure and convenient installation, this tool enables tower unblocking operations to be completed without stopping the equipment. Using this tool to unblock towers eliminates the need for external force, making the operation simple and efficient. The tool is easy to install, safe to use, and reduces the environmental risks and waste of chemicals and sulfur paste falling to the ground after unblocking. It has broad application prospects and extremely high promotional value.

The closed end of the sealing mechanism 1 has a threaded hole 17, which facilitates the installation of the locking sleeve 3, making it easy to assemble, disassemble, and use. A sealing groove 18 is located on the outer side of the threaded hole 17 on the outer side of the sealing mechanism 1; the sealing groove 18 facilitates the mating with the locking sleeve 3, allowing for a seal between the locking sleeve 3 and the sealing mechanism 1. Multiple first connecting holes 15 and second connecting holes 16 are evenly distributed on the flange 14, with the first connecting holes 15 and second connecting holes 16 staggered; this structure facilitates the connection of the flange 14 to the tower bottom using bolts.

[0037] like Figure 4 As shown, the end of the moving rod 2 without the four-corner drill bit 21 is provided with a stud 23. The stud 23 facilitates the connection of the moving rod 2 to other components. Furthermore, two first disassembly and assembly platforms 22 are symmetrically provided on the side of the moving rod 2 near the stud 23. The first disassembly and assembly platforms 22 facilitate the use of a wrench to easily disassemble and assemble the moving rod 2.

[0038] like Figure 5 As shown, the locking sleeve connector 3 has two symmetrical second disassembly and assembly platforms 31 on its side, which are used to disassemble and assemble the locking sleeve connector 3 with the help of a wrench; the end of the locking sleeve connector 3 facing the sealing mechanism 1 has an adapter ring 33, which is threadedly connected to the threaded hole 17, facilitating the disassembly and assembly of the locking sleeve connector 3. Furthermore, the sealing sleeve connector has a sealing gasket 32 ​​on its side facing the sealing mechanism 1, which is aligned with the sealing groove 18; this structure facilitates the pressing of the sealing gasket 32 ​​into the sealing groove to achieve a seal.

[0039] like Figure 6 As shown, it also includes connecting rods 4, of which multiple connecting rods 4 are provided. These connecting rods 4 can be spliced ​​together, and the end of the connecting rod 4 near the moving rod 2 is detachably connected to the moving rod 2. This structure facilitates extension of the moving rod 2 when the blockage is too deep or the moving rod 2 is insufficient. One end of the connecting rod 4 has a threaded groove 41, which facilitates connection between the connecting rod 4 and the moving rod 2 or adjacent connecting rods 4. The other end has a stud 23, used to connect with the threaded groove 41 of the adjacent connecting rod 4. Two first disassembly / assembly platforms 22 are symmetrically provided on the side of the connecting rod 4 near the threaded groove 41 and the stud 23. The first disassembly / assembly platforms 22 facilitate the disassembly / assembly of the connecting rod 4 by engaging the handle 13.
