Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hydrogen peroxide decomposition, in particular to a vaporized hydrogen peroxide catalytic decomposition device. Background Art
[0002] Currently, the decomposition process of hydrogen peroxide in a transfer window widely relies on filters with special structures that integrate the decomposition function. The core materials are mostly high-efficiency metal oxides or noble metal catalysts, etc. Such materials significantly accelerate the conversion process of hydrogen peroxide into harmless water and oxygen, although their manufacturing process is complex and the cost is relatively high.
[0003] These advanced filters not only undertake the basic task of filtering impurities, but also play a key role after the hydrogen peroxide sterilization process - effectively decomposing the remaining hydrogen peroxide into pure water and oxygen, fundamentally reducing the risk of harmful residues and ensuring the safety and cleanliness of the environment.
[0004] In actual operation, vaporized hydrogen peroxide enters the system through a specific inlet. However, due to the high humidity carried by the gas during the sterilization process, some water vapor may preferentially occupy the effective catalytic sites of the catalyst layer, thereby weakening the overall catalytic efficiency. Once hydrogen peroxide comes into contact with the catalyst, it will quickly and efficiently decompose into oxygen and water, and then be discharged from the system. It should be noted that water vapor residues are likely to form on the surface of the catalyst during the catalytic reaction process, which to a certain extent affects the effect of subsequent catalytic reactions.
[0005] In addition, for the drying requirement of the catalyst after long-term operation, the fixed installation angle of the catalyst in the traditional design limits the improvement of the drying efficiency, resulting in a relatively time-consuming process and low energy utilization rate.

[0030] In an embodiment of the present invention, as Figure 2 shown, the water vapor adsorption component 20 includes a movable shaft rod 201, a top plate 202, and an adsorption member 203.
[0031] Among them, the movable shaft rod 201 is movably arranged in the catalytic decomposition box body 101.

[0032] It should be noted that the movable shaft rod 201 is lifted and adjusted in the catalytic decomposition box body 101. When the movable shaft rod 201 moves up and down, it abuts against the bottom of the adsorption member 203 through the top plate 202, thereby driving the adsorption member 203 to adjust the inclination angle.
[0033] In an embodiment of the present invention, as Figure 2 shown, the adjusting component 40 includes an adjusting member 401, a fastening plate 402, an adjusting screw 403, and a fastening collar 404.
[0034] Among them, the adjusting member 401 is movably arranged in the catalytic decomposition box body 101, and the adjusting member 401 is connected to the movable shaft rod 201. The fastening plate 402 is arranged on the adjusting member 401. The adjusting screw rod 403 is movably arranged on the fastening plate 402. The fastening collar 404 is arranged in the catalytic decomposition box body 101, and the adjusting member 401 is movably arranged in the fastening collar 404.
[0035] It should be noted that the adjusting member 401 is connected to the movable shaft rod 201, so as to drive the lifting adjustment of the movable shaft rod 201 from the outside of the catalytic decomposition box body 101. The adjusting screw rod 403 is thread-adjusted in the fastening plate 402, and the adjusting screw rod 403 abuts against the top wall of the catalytic decomposition box body 101, so as to adjust the height of the adjusting member 401 and support and fix it. A sealing rubber ring is provided at the connection between the fastening collar 404 and the movable shaft rod 201 to effectively prevent the internal hydrogen peroxide gas from leaking out.
[0036] In an embodiment of the present invention, as Figure 3 shown, the adjusting member 401 includes a pull rod 4011 and a threaded connecting rod 4012.
[0037] Among them, the pull rod 4011 is movably arranged in the fastening collar 404, and the threaded connecting rod 4012 is arranged on the bottom wall of the pull rod 4011.
[0038] It should be noted that the threaded connecting rod 4012 is provided on the bottom wall of the pull rod 4011, so that the pull rod 4011 is convenient to connect with the catalytic decomposition box body 101 and the movable shaft rod 201 inside the catalytic decomposition box body 101.
[0039] In an embodiment of the present invention, as Figure 3 shown, the movable shaft rod 201 includes a movable shaft 2011 and an internal threaded hole 2012.
[0040] Among them, the movable shaft 2011 is movably arranged in the catalytic decomposition box body 101, the internal threaded hole 2012 is arranged on the top wall of the movable shaft 2011, and the internal threaded hole 2012 is threadedly connected to the threaded connecting rod 4012.
[0041] It should be noted that through the threaded connection between the internal threaded hole 2012 and the threaded connecting rod 4012, the movable shaft 2011 is threadedly connected to the pull rod 4011, and then the lifting adjustment of the movable shaft 2011 is driven.
[0042] In an embodiment of the present invention, as Figure 2 shown, the adsorbing member 203 is an outer shell body, both ends of the outer shell body are respectively provided with arc-shaped chamfers, and the inner cavity of the outer shell body is filled with an adsorbent.
[0043] It should be noted that the adsorbent is an activated alumina adsorbent, while the hydrogen peroxide catalytic component 30 is an activated manganese dioxide catalyst. The outer diameter of one end of the arc chamfer on the adsorbing member 203 is larger than that of the other end. The adsorbing member 203 is rotatably arranged in the catalytic decomposition box body 101 through a shaft. When rotating, the end with the larger outer diameter of the adsorbing member 203 faces downward.
[0044] Specifically, the steps for catalytically decomposing vaporized hydrogen peroxide are as follows: The hydrogen peroxide gas is transported into the catalytic decomposition box body 101 through the ventilation pipe 102. The hydrogen peroxide gas first passes through the water vapor adsorption member 20 to adsorb the water vapor in the hydrogen peroxide gas. After installing the water vapor adsorption member 20 in the catalytic decomposition box body 101, the movable shaft 2011 and the pull rod 4011 are connected through the threaded connection of the threaded connecting rod 4012 and the internal threaded hole 2012. The upward movement of the pull rod 4011 drives the top plate 202 to move upward. At this time, the top plate 202 pushes the adsorbing member 203 to rotate, so that the adsorbing members 203 come into contact with each other, thereby adsorbing the water vapor in the flowing hydrogen peroxide gas. And the hydrogen peroxide is decomposed into oxygen and water by the activated manganese dioxide catalyst in the hydrogen peroxide catalytic component 30. After repeatedly adsorbing multiple times, hot air is introduced into the catalytic decomposition box body 101 through the drying pipe 103. The hot air heats and dries the adsorbing member 203 to achieve the purpose of restoring the activity of the catalyst.
[0045] In summary, an apparatus for catalytically decomposing vaporized hydrogen peroxide according to an embodiment of the present invention adopts a method of first adsorbing water vapor and then catalytically decomposing it. At the same time, it is convenient to adjust the angle of the adsorbing member, and adjust its different angles when adsorbing water vapor and drying water vapor to ensure the adsorption efficiency and drying efficiency.
[0046] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and deformations to the above embodiments within the scope of the present invention.
