[0002] In modern industrial fields such as petroleum, chemical industry, power generation, etc., air coolers (referred to as "air coolers" for short) are widely used as important cooling equipment for cooling various process media such as oil and gas, methanol, etc. The air cooler cools the medium through its tube bundle structure, and the tube bundle is usually connected by a plurality of tubes and plugs (such as flanges, joints, etc.).

[0003] Under long-period operation conditions, the air cooler tube bundle plug is prone to leakage due to equipment vibration and oxidation corrosion of the operating medium. Once leakage occurs, the traditional treatment method is usually to stop and overhaul, and to use manual or mechanical tools for fastening. However, in actual operation, fastening often cannot completely solve the problem, and frequent stoppage for repair not only increases production costs, but also may cause safety risks.

[0004] Existing plugging methods such as manual stuffing and temporary repair welding are complex and unstable in effect. These methods not only require professional technicians to operate, but also have certain dangers during operation in high-temperature and high-pressure environments. In addition, the existing plugging methods often cannot monitor the leakage in real time, and it is difficult to meet the high requirements of modern industry for safety and reliability.

[0034] To make the objectives, solutions, and advantages of the technical solutions of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

[0035] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] As described above, during the use of traditional air coolers, leaks may occur in the tube bundle plugs due to equipment vibration and oxidation corrosion of the operating medium, requiring the leaking tube bundle plugs to be plugged.

[0037] To at least partially address one or more of the aforementioned problems and other potential issues, an example embodiment of this application provides an online safety leak-proof device for leaking plugs in a crude methanol synthesis condenser. This sealing device includes: a cup 1, with its open end covering the plug 6 at the end of the air cooler tube bundle 5; a glue injection valve 2, one end connected to the interior of the cup 1 and the other end connected to a glue injection gun; and a U-shaped clamp 3, its opening clamped onto the outside of the air cooler 4. The U-shaped clamp 3 includes: two sets of L-shaped plates 31, spaced apart on both sides of the outer wall of the air cooler 4, with the space between the two sets of L-shaped plates 31 being the side of the air cooler 4 closest to the plug 6; a mounting plate 32, with the two sets of L-shaped plates 31 spaced apart at both ends of the mounting plate 32's surface; and a threaded telescopic assembly 33, disposed between the mounting plate 32 and the two sets of L-shaped plates 31.

[0038] In use, the cup 1 is placed over the leaking tube plug 6, and then the U-shaped clamp 3 is clamped around the air cooler 4. During clamping, two L-shaped plates 31 are placed on the upper and lower outer walls of the air cooler 4 respectively, and the corners of the L-shaped plates 31 are engaged with the outer wall of the air cooler 4. The threaded telescopic assembly 33 is screwed on so that the mounting plate 32 moves toward the outer wall of the air cooler 4 with the tube plug 6 until the mounting plate 32 abuts against the bottom of the cup 1, sealing the gap between the cup 1 and the surface of the air cooler 4. Then, the glue gun is connected to the glue injection valve 2, and high-pressure graphite glue, PTFE glue, or silicone rubber is injected into the cup 1 through the glue gun so that the glue fills and seals the leak in the tube plug 6. Then, the glue injection valve 2 is closed, and the glue gun is removed. The installation is convenient and efficient, and the leaking tube plug 6 can be repaired without stopping the machine.

[0039] Please see Figures 1-9 In some embodiments, the cup 1 includes: a cup-shaped body 11, which covers the outside of the tubular plug 6; a recess 12, which is disposed on the outer wall of the bottom of the cup-shaped body 11; a magnetic block 13, which is disposed in the recess 12 and magnetically connected to the mounting plate 32; and a perforation 14 through which the glue injection valve 2 communicates with the interior of the cup-shaped body 11.

[0040] In use, since the outer wall of the air cooler 4's chassis is sometimes made of non-magnetic metal, when installing the U-shaped clamp 3 after the cup 1 is placed outside the tube bundle plug 6, it is necessary to manually hold the cup 1 and install the U-shaped clamp 3, which makes the operation difficult. Therefore, a magnetic block 13 is set at the bottom of the cup-shaped body 11, so that the cup-shaped body 11 can be attracted to the mounting plate 32 by the magnetic block 13. Then, the distance between the mounting plate 32 and the tube bundle plug 6 is adjusted by the threaded telescopic assembly 33. When the cup-shaped body 11 is close to the tube bundle plug 6, the cup-shaped body 11 is moved so that the cup-shaped body 11 is aligned with the tube bundle plug 6. Then, the threaded telescopic assembly 33 is continued to be screwed, and finally the cup-shaped body 11 is placed on the outside of the tube bundle plug 6. Thus, during the screwing of the threaded telescopic assembly 33, it is not necessary to manually hold the cup-shaped body 11, reducing the installation difficulty and improving the installation efficiency.

[0041] Please see Figures 1-9 In some embodiments, the surface of the mounting plate 32 is provided with a plurality of strip-shaped sliding holes 34, and each strip-shaped sliding hole 34 is evenly distributed at both ends of the mounting plate 32; wherein the length direction of each strip-shaped sliding hole 34 is parallel to the length direction of the mounting plate 32; the threaded telescopic component 33 is provided in the strip-shaped sliding hole 34, and the threaded telescopic component 33 passes through the strip-shaped sliding hole 34 and is connected to one end of the L-shaped plate 31.

[0042] The threaded telescopic assembly 33 includes: a bolt 331, which is disposed in each of the strip-shaped sliding holes 34, with one end having a bolt head disposed on the side of the mounting plate 32 away from the air cooler 4, and the other end connected to one end of the L-shaped plate 31; and an adjusting nut 332, which is disposed on the side of the mounting plate 32 away from the air cooler 4 and is threadedly connected to the bolt 331.

[0043] When in use, turn the adjusting nut 332 so that the adjusting nut 332 moves closer to the mounting plate 32 and eventually pushes the mounting plate 32 closer to the air cooler 4, thereby achieving the purpose of adjusting the distance between the mounting plate 32 and the air cooler 4.

[0044] Please see Figures 1-9 In some embodiments, the mounting plate 32 is further provided with an auxiliary baffle 35 on the side near the air cooler 4, and the auxiliary baffle 35 is disposed between the plurality of cups 1 and the mounting plate 32.

[0045] The mounting plate 32 has a plurality of insertion holes 36 evenly distributed on the side near the air cooler 4; the auxiliary baffle 35 has an insertion rod 37 at the center on the side away from the cover cup 1; wherein the insertion rod 37 is located in the insertion hole 36.

[0046] In use, under certain circumstances, the adjacent tube plugs 6 of the air cooler 4 may leak simultaneously. When plugging the tube plugs 6, multiple cup-shaped bodies 11 are magnetically attached to one side of the auxiliary baffle 35, and the insertion rod 37 on the other side of the auxiliary baffle 35 is inserted into the insertion hole 36 on the mounting plate 32. The insertion rod 37 can rotate within the insertion hole 36. Then, the U-shaped clamp 3 is installed to cover all the leaking tube plugs 6 located on the same straight line with the cup-shaped body 11. This allows multiple leaking tube plugs 6 located on the same straight line to be plugged simultaneously.

[0047] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.

[0048] The terminology used herein is chosen to best explain the principles, practical applications, or technological improvements to the various embodiments, or to enable those skilled in the art to understand the embodiments disclosed herein.

[0049] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
