Description

Technical Field

[0001] This utility model relates to the technical field of gas purification equipment, specifically an industrial oxygen gas purification and carbon removal adsorption tower. Background Technology

[0002] In the industrial oxygen gas production process, the main purification techniques for oxygen gas include: 1. Cryogenic air separation: This method utilizes the differences in boiling points of various air components to separate oxygen through multi-stage compression, cooling, and liquefaction. However, this technology requires large equipment investment and consumes a lot of energy. 2. Pressure-Switching Adsorption (PSA): This method utilizes the selective adsorption properties of zeolite molecular sieves for nitrogen and oxygen. However, the oxygen purity is typically only 90%-95%, making it suitable for small to medium-scale applications. 3. Membrane separation method: This method utilizes the selective permeability of polymer membranes to gas molecules. The oxygen produced by this technology has a lower purity (30%-50%), making it suitable for flexible oxygen supply applications.

[0003] Existing adsorption towers typically contain molecular sieves to achieve continuous oxygen production. However, the molecular sieves are usually fixed by bolting a pressure sieve plate directly onto them. Although the support plate is low, the molecular sieves are only manually compacted during the initial filling. Once the system is running, the settling of the molecular sieves will inevitably create space, requiring entry into the tower for inspection and adjustment of the compaction. The molecular sieves will then vibrate and wear down within this space, leading to pulverization and a significant reduction in the lifespan of the device. To address these issues, we propose an industrial oxygen gas purification and carbon removal adsorption tower. Utility Model Content

[0004] The purpose of this invention is to provide an industrial oxygen gas purification and carbon removal adsorption tower to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an industrial oxygen gas purification and carbon removal adsorption tower, comprising a tower body, a top cover fixedly installed at the top of the tower body, a bottom cover fixedly installed at the bottom of the tower body, a support ring fixedly sleeved in the middle of the tower body, the bottom end of the support ring abutting against the top edge of an activated carbon plate, the bottom edge of the activated carbon plate abutting against a lower fixing ring, and the lower fixing ring being snapped into the bottom of the tower body; The top of the support ring abuts against the bottom edge of the frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting multiple pressing components, downward pressure is applied to the pressing screen plate to achieve automatic pressing of the molecular sieve, which helps to reduce production costs. At the same time, when the molecular sieve settles during operation, the elastic downward pressure of the pressing components extends downward to compensate for the space generated by the settlement, preventing the molecular sieve from jumping and pulverizing, and ensuring reliable pressing. 2. When the molecular sieve exhibits jumping behavior, the resistance of the damping rod reduces the amplitude of the jumping. At the same time, the downward pressure of the pressing assembly can be adjusted, allowing for timely adjustment of the downward pressure according to the operating conditions. 3. The lower fixing ring is fixed by a threaded structure, which facilitates the disassembly and replacement of the lower fixing ring. Attached Figure Description

[0017] Reference Figure 1-4This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, one end of a plurality of support legs 4 is fixedly connected to the bottom periphery of the tower body 1, and the support legs 4 support the entire tower body 1.

[0018] Specifically, an air outlet pipe 6 is fixedly connected to one side of the top cover 2, and an air inlet pipe 5 is fixedly connected to the center of the bottom cover 3. The top cover 2 and the bottom cover 3 are fixedly installed at the top and bottom ends of the tower body 1 through a flange structure.

[0019] Specifically, the bottom end of the tower body 1 is provided with multiple mounting slots 101. The mounting slots 101 are T-shaped structures.

Each mounting block 91 has a through hole, and the hole is slidably sleeved with the threaded rod 102.

[0020] When disassembling the activated carbon plate 8, open the bottom cover 3 to expose the bottom of the tower body 1. Use a socket tool to remove the fixing nut 103, and then remove the lower fixing ring 9. At this time, the activated carbon plate 8 falls off. Then, the new activated carbon plate 8 is re-inserted into the tower body 1. The support ring 10 positions the new activated carbon plate 8. Then, the lower fixing ring 9 is re-inserted. The mounting blocks 91 are inserted into the mounting grooves 101 and the threaded rods 102. The mounting blocks 91 are installed and fixed by the threaded engagement of the fixing nut 103 and the threaded rods 102, thereby limiting and fixing the activated carbon plate 8.

Finally, the oxygen gas is discharged and collected from the outlet pipe 6. When disassembling the activated carbon plate 8, the bottom cover 3 is opened to expose the bottom of the tower body 1. The fixing nut 103 is removed using a socket tool, and then the lower fixing ring 9 can be removed. At this time, the activated carbon plate 8 falls off.
