[0019] like Figures 1-4 As shown, a catalytic tube for a multi-segment mercury analyzer with a long service life includes three filter units connected end to end.

[0020] The filter unit includes a cylindrical body 1, a male connector 2, a female connector 3, and a partition unit disposed inside the cylindrical body 1. The cylindrical body 1 is cylindrical. The male connector 2 and the female connector 3 are respectively disposed at both ends of the cylindrical body 1. The male connector 2 is provided with a threaded post, and the female connector 3 is provided with a threaded groove. The threaded post matches the threaded groove, and the threaded post is located on the side of the male connector 2 away from the cylindrical body 1.

[0021] The partition unit includes an outer partition and an inner partition. The inner partition includes a partition plate 4 and a partition cylinder 6. The inner partition also includes a guide plate 5 and a guide cylinder 7. Both the partition plate 4 and the guide plate 5 are circular and are disposed inside the cylinder 1. The partition plate 4 and the guide plate 5 are parallel and coaxially arranged with the cylinder 1. The partition plate 4 and the guide plate 5 are located at opposite ends within the cylinder 1. The outer edges of the partition plate 4 and the guide plate 5 are sealed to the inner wall of the cylinder 1. The partition cylinder 6 is open at both ends and coaxially arranged with the cylinder 1. One end of the partition cylinder 6 is sealed to the partition plate 4. A circular hole 11 is provided at the center of the flow guide 6, the center of which coincides with the center of the partition plate 4. The diameter of the circular hole 11 is smaller than the diameter of the partition cylinder 6. The flow guide 7 is sleeved on the partition cylinder 6 and is coaxially arranged with the partition cylinder 6. The diameter of the flow guide 7 is larger than the diameter of the partition cylinder 6. One end of the flow guide 7 is sealed to the flow guide plate 5. There is a gap between the end of the partition cylinder 6 away from the partition plate 4 and the flow guide plate 5. There is also a gap between the end of the flow guide 7 away from the flow guide plate 5 and the partition plate 4. The flow guide plate 5 is provided with an annular hole 11, the center of which coincides with the center of the flow guide plate 5. The inner diameter of the annular hole 11 is larger than the outer diameter of the flow guide 7.

[0022] Preferably, a sealing ring 10 is provided at the connection between the male connector 2 and the cylinder 1, and the sealing ring 10 is sleeved on the male connector 2.

[0023] Preferably, the cylinder 1 contains material, which is located between the partition plate 4 and the guide plate 5.

[0024] Preferably, a first filter cotton 8 is provided on one side of the partition plate 4. The first filter cotton 8 is cylindrical and its diameter is slightly larger than the inner diameter of the cylinder 1. The first filter cotton 8 is located inside the cylinder 1 and between the partition plate 4 and the male connector 2.

[0025] Preferably, a second filter cotton 9 is provided on one side of the guide plate 5. The second filter cotton 9 is cylindrical and its diameter is slightly larger than the inner diameter of the cylinder 1. The second filter cotton 9 is located inside the cylinder 1 and between the guide plate 5 and the female connector 3.

[0026] In fact, the number of filter units can be set according to actual needs, and the amount of catalyst material filled in each filter unit can also be adjusted according to actual needs.

[0027] The male connector 2 and female connector 3 of two adjacent filter units are threaded together, and the sealing ring 10 is used to seal the connection to prevent air leakage.

[0028] Gas enters the cylinder 1 from the male connector 2, first passes through the first filter cotton 8, then enters the separator 6 through the round hole 11 on the separator plate 4, then flows back from the gap between the separator 6 and the guide plate 5 to the gap between the separator 6 and the guide tube 7, then enters the gap between the guide tube 7 and the cylinder 1 through the gap between the guide tube 7 and the separator plate 4, and then flows out from the annular hole 12 on the guide plate 5. After passing through the second filter cotton 9, it exits from the female connector 3.

[0029] This actually forms an S-shaped path, which prolongs the catalytic time and improves the catalytic effect.

[0030] During normal operation, the frontmost filter unit experiences the greatest consumption. Even when the frontmost filter unit becomes saturated and unusable, the rearmost filter units still retain adsorption capacity. Therefore, simply removing the frontmost filter unit and replacing it with a new one is sufficient. Alternatively, the rearmost filter unit can be moved forward one position to fully utilize the catalytic material, improve material utilization, and reduce operating costs. Furthermore, the disassembly and assembly of the catalytic unit does not affect the overall structure of other filter units; only simple replacement is required, significantly reducing the probability of structural damage and extending service life.

[0031] Compared with existing technologies, this long-life multi-segment mercury analyzer catalytic tube adopts a multi-segment split structure design, which is convenient for disassembly and maintenance. After the first segment is saturated, it can be directly replaced. Moreover, the usage order of each segment can be changed according to the actual situation, thereby improving the utilization rate of the catalytic material and reducing the operating cost. The internal and external separators extend the catalytic time and improve the catalytic effect. Furthermore, it does not require frequent disassembly and assembly for internal material replacement, ensuring the integrity of the overall structure and extending its service life.

[0032] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
