Abstract
Description
Technical Field
[0001] This utility model relates to the field of adsorption equipment technology, specifically to a novel high-efficiency adsorption device for molecular sieve desiccants. Background Technology
[0002] Molecular sieve desiccants are a type of high-efficiency adsorbent with a uniform microporous structure that can selectively adsorb molecules of different sizes. They exhibit excellent performance in adsorbing moisture and impurities and are widely used in petrochemical, natural gas and other fields.
[0003] A search revealed a patent, CN217247866U, which discloses a molecular sieve adsorption device. This device includes a waste gas treatment chamber with an adsorption mechanism movably connected to its inner side. The adsorption mechanism includes a limiting slide, a lifting platform movably connected to the inner side of the limiting slide, a magnetic stake fixedly connected to the top of the limiting slide, an adsorption top cover fixedly connected to the top of the adsorption top cover, and an iron core fixedly connected to the top of the iron core. An energized coil is wound around the outer side of the iron core. This invention, through the design of the limiting slide, movably connects the adsorption mechanism to the inner wall of the waste gas treatment chamber. Simultaneously, through the cooperation of the iron core, the energized coil, and the magnetic stake, the adsorption top cover and the limiting slide are fixed together when energized, facilitating the lifting of the entire adsorption mechanism. When power is off, the adsorption top cover can be easily removed, and the molecular sieve can be replaced via the lifting platform. This ensures sealing and ease of replacement, improving the waste gas treatment effect.
[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:
[0005] In reality, when molecular sieves adsorb moisture, they have a certain saturation threshold. When the molecular sieve reaches the upper limit of the adsorption threshold, its adsorption effect will be greatly reduced, requiring replacement. This involves removing the molecular sieve for replacement or regeneration. However, the aforementioned prior art requires stopping the exhaust gas discharge, removing the molecular sieve, and then reinstalling a new one. During this process, the exhaust gas cannot be dried and adsorbed, thus reducing the overall adsorption efficiency of the adsorption device. Therefore, there is an urgent need in this field to improve the adsorption device to overcome the shortcomings of the existing technology. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel high-efficiency adsorption device for molecular sieve desiccant, comprising two symmetrical through frames, each through frame having a first guide cover fixedly installed on its opposite side, a connecting pipe fixedly installed between the two first guide covers, each connecting pipe having a first electrically controlled valve fixedly installed on both sides for opening and closing the connecting pipe, a connecting main pipe fixedly installed on the side of the connecting pipe away from the through frame, a molecular sieve placed inside the through frame, and several first through holes adapted to the first guide covers being opened on the opposite sides of the through frame.

[0028] 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 some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figures 1-7 A novel high-efficiency adsorption device for molecular sieve desiccant includes two symmetrical through frames 1. A first guide cover 2 is fixedly installed on the opposite sides of each through frame 1. A connecting pipe 3 is fixedly installed between the two first guide covers 2. A first electrically controlled valve 4 for opening and closing the connecting pipe 3 is fixedly installed on both sides of the connecting pipe 3. A connecting main pipe 5 is fixedly installed on the side of the connecting pipe 3 away from the through frame 1. A molecular sieve is placed inside the through frame 1. Several first through holes 6 adapted to the first guide covers 2 are opened on the opposite sides of each through frame 1.
[0030] Specifically, when molecular sieve desiccant is needed to adsorb moisture in the discharged medium, the first electrically controlled valve 4 at the left end of the connecting pipe 3 is opened, and the first electrically controlled valve 4 at the right end is closed. The discharged medium is discharged into the connecting pipe 3 through the main discharge pipe 5 at one end, and is transported to the first guide cover 2 through one end of the connecting pipe 3. It then enters the passing frame 1 through the first through hole 6 on the side of the frame 1. When it passes through the molecular sieve placed in the passing frame 1, the molecular sieve desiccant adsorbs the water vapor contained in the discharged medium and is discharged again through the first guide cover 2, the connecting pipe 3, and the main discharge pipe 5 on the other side. When it is necessary to replace the molecular sieve in the passing frame 1, the first electrically controlled valve 4 at the left end of the connecting pipe 3 is closed, and the first electrically controlled valve 4 at the right end is opened. The discharged medium is discharged into another passing frame 1 through the other end of the connecting pipe 3 for adsorption treatment. This allows the molecular sieve desiccant in the passing frame 1 to be replaced. When replacing the molecular sieve desiccant, it is not necessary to stop the delivery of the discharged medium, thus improving the adsorption efficiency of the adsorption device.
[0031] As a technical optimization of this utility model, the frame 1 is provided with a plurality of plug-in frames 7, and a plurality of first plug-in slots 8 adapted to the plug-in frames 7 are opened on one side of the frame 1. The plug-in frames 7 are provided with second through holes 9 adapted to the first through holes 6 on opposite sides. A heating element 10 for heating is provided at the bottom of the plug-in frame 7. A second plug-in slot 11 adapted to the heating element 10 is opened on one side of the plug-in frame 7. A second guide cover 12 is provided on one side of the frame 1. A steam exhaust pipe 13 is fixedly installed on the side of the second guide cover 12 away from the frame 1. A second electrically controlled valve 14 for opening and closing the steam exhaust pipe 13 is fixedly installed on the side of the steam exhaust pipe 13. An exhaust fan 15 is fixedly installed in the steam exhaust pipe 13. A plurality of third through holes 16 are opened on the side of the plug-in frame 7 near the second guide cover 12.
[0032] Specifically, the molecular sieve is placed inside the insertion frame 7, which is inserted into the through frame 1 via the first insertion slot 8, facilitating the removal of the insertion frame 7 and the handling of the molecular sieve. When the water absorption effect of the molecular sieve in the insertion frame 7 of a certain through frame 1 deteriorates, the corresponding first electrically controlled valve 4 is closed, and the heating element 10 is turned on. The heating element 10 can perform high-temperature heating, heating the molecular sieve inside the insertion frame 7. After the molecular sieve is heated, the water vapor inside it is discharged, and the second electrically controlled valve 14 and the exhaust fan 15 are turned on. The exhaust fan 15 discharges the water vapor inside the through frame 1 through the third through hole 16 and the exhaust pipe 13. After the water vapor is discharged, the molecular sieve can still be reused, allowing for multiple uses of the molecular sieve, reducing the number of times the molecular sieve needs to be replaced, and further improving the adsorption efficiency of the adsorption device.
[0033] As a technical optimization of this utility model, a U-shaped snap-fit bracket 17 is fixedly installed on the side of the frame 1 near the second guide cover 12. Snap-fit strips 18 adapted to the snap-fit bracket 17 are fixedly installed on the opposite sides of the second guide cover 12. Mounting flanges 19 for installation are fixedly installed on the opposite ends of the two main pipes 5. The snap-fit bracket 17 and snap-fit strips 18 have elastic sealing elements on their facing sides. The second guide cover 12 is inserted into the snap-fit bracket 17 via the snap-fit strips 18, thus connecting the second guide cover 12 to the frame 1. The elastic sealing elements seal the connection between the frame 1 and the second guide cover 12. The mounting flanges 19 facilitate the installation of the entire device.
