Description

Technical Field

[0001] The utility model relates to the technical field of methane removal mechanisms for distillation towers, in particular to a methane removal mechanism for a krypton-xenon distillation tower. Background Art

[0002] A krypton-xenon distillation tower is a device specifically designed for separating and purifying krypton and xenon gases. It utilizes the difference in boiling points between krypton and xenon to separate the two gases through multiple partial condensation and evaporation processes within the distillation tower. Methane treatment is a crucial step in the extraction and refining of krypton and xenon. To ensure production safety, the concentration of methane in the krypton-xenon mixture needs to be reduced.

[0003] A common method for removing methane is to use a palladium catalyst. At temperatures of 480-500°C, oxygen and methane react chemically to remove the methane. The reaction products, carbon dioxide and water, are then removed by adsorption using a molecular sieve. However, since molecular sieves require replacement after prolonged use and are typically integral, making them difficult to remove during disassembly, a methane removal mechanism using a krypton-xenon distillation tower has been proposed to address these issues. Utility Model Content

[0004] The utility model aims to provide a methane removal mechanism for a krypton-xenon distillation tower, so as to solve the problem that the molecular sieve is inconvenient to disassemble, remove and replace after use.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A methane removal mechanism for a krypton-xenon distillation tower comprises a distillation tower body for separating and purifying krypton and xenon, a cover plate being rotatably connected to the front side of the distillation tower body, a through hole being provided on one side of the distillation tower body, a slide groove being provided on the inner wall of the distillation tower body, a roller being fitted in the slide groove provided on the inner wall of the distillation tower body, a rotating plate being provided on the outer side of the roller, a limit plate being fixedly connected to one side of the rotating plate, a support plate being fixedly connected to one side of the limit plate, a fiber bag being fitted on the surface of the support plate, and a molecular sieve body being provided in the fiber bag.

[0007] Preferably, Velcro is embedded in the bottom of the fiber bag and the top of the rotating plate, and the fiber bag and the rotating plate are tightly fitted together by the Velcro.

[0008] Preferably, a rubber layer is fixedly connected to the inner side of the cover plate, and the rubber layer is in close contact with the outer surface of the distillation tower body.

[0009] Preferably, grooves are provided on one side of the cover plate and the rubber layer, a pull rod is provided in the grooves provided on one side of the cover plate and the rubber layer, a spring is provided on the outside of the pull rod, and a clamping block is fixedly connected to one side of the pull rod.

[0010] Preferably, magnetic blocks are provided in both the distillation tower body and the clamping block, and one end of the clamping block is provided in the distillation tower body.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] In the utility model, the distillation tower body, rotating plate, limiting plate, supporting plate, molecular sieve body and fiber bag are provided. The molecular sieve absorbs the remaining carbon dioxide and water after the methane is removed through the fiber bag. The supporting plate and the rotating plate support the fiber bag with the molecular sieve body. The limiting plate simply limits the position of the fiber bag. The position of the fiber bag is fixed by the provided Velcro. Through the provided cover plate, through hole, rotating plate, roller and slide groove, the user can open the cover plate, put his hand into the through hole, move the fiber bag up and take it out, and then Rotate the rotating plate and the roller slides in the slide groove, which makes it easy to take out the remaining fiber bags in sequence. The rubber layer is provided to increase the sealing effect between the cover plate and the distillation tower body. Compared with the overall removal of the molecular sieve in the prior art, the cover plate area becomes smaller, which increases the sealing effect of the distillation tower body and facilitates the removal of the fiber bag containing the molecular sieve body. Through the provided rubber layer, pull rod, card block, magnetic block, spring and groove, the user holds the pull rod and pulls it outward before opening the cover, driving the card block away from the distillation tower body, which is convenient for fixing the cover plate.

The fiber bag 10 and the rotating plate 4 fit tightly together through the Velcro 11, which facilitates the disassembly and assembly of the fiber bag 10; a rubber layer 12 is fixedly connected to the inner side of the cover plate 2, and the rubber layer 12 fits tightly against the outer surface of the distillation tower body 1, thereby increasing the sealing effect between the cover plate 2 and the distillation tower body 1; a groove 17 is provided on one side of the cover plate 2 and the rubber layer 12, and a pull rod 13 is provided in the groove 17 provided on one side of the cover plate 2 and the rubber layer 12, and a spring 16 is provided on the outside of the pull rod 13, and a card block 14 is fixedly connected to one side of the pull rod 13 to facilitate the fixation of the cover plate 2 after it is closed; a magnetic block 15 is provided in the distillation tower body 1 and in the card block 14, and one end of the card block 14 is provided in the distillation tower body 1 to facilitate the fixation of the card block 14.

[0025] Working process: During the operation of the krypton-xenon distillation tower, krypton and xenon are separated. In the process of methane being removed, carbon dioxide and water are adsorbed and removed by the molecular sieve body 9. After long-term use, the effect of the molecular sieve body 9 gradually decreases. At this time, it needs to be replaced. The user holds the pull rod 13 and pulls it outward, driving the card block 14 to slide in the groove 17. The spring 16 is compressed until one end of the card block 14 completely leaves the distillation tower body 1. At this time, the cover plate 2 is held and rotated outward to expose the through hole 3. The user reaches into the through hole 3 and then moves one of the fiber bags 10 containing the molecular sieve body 9 upward so that the Velcro 11 at the bottom of the fiber bag 10 is away from the Velcro 11 embedded in the top of the rotating plate 4. Then, the fiber bag 10 is taken out. The user rotates the rotating plate 4 to one side through the through hole 3. The roller 5 slides in the slide groove 6, driving the limit plate 7, the support plate 8, and the remaining fiber bags 10 to rotate in the same direction until another After the replacement is completed, the user holds the pull rod 13 to control the card block 14 to move into the groove 17, and then rotates the cover plate 2 in the opposite direction until the rubber layer 12 is tightly fitted with the outer side of the distillation tower body 1. At this time, the pull rod 13 is released, and under the action of the elastic force of the spring 16 and the magnetic attraction between the magnetic blocks 15, the card block 14 is inserted into the distillation tower body 1 to fix the position of the cover plate 2. By setting up several fiber bags 10 with molecular sieve bodies 9 and using them in conjunction with the rotating plate 4, it is convenient to remove and replace the failed molecular sieve body 9.
