Description

Technical Field

[0001] This utility model relates to the technical field of functional materials for the catalytic oxidation of formaldehyde at room temperature, specifically to an air purification filter of NanoCaptur, a manganese-based catalyst nanofiber membrane for decomposing formaldehyde. Background Technology

[0002] While improving our living standards, it also brings a certain degree of pollution to indoor and outdoor air. Formaldehyde, in particular, is widely used in indoor decoration materials, resulting in high levels of formaldehyde in indoor spaces, which can have a significant impact on people's health.

[0003] However, existing formaldehyde filtration methods mostly rely on activated carbon for adsorption, which requires the internal activated carbon material to be replaced after a long period of use. This usually requires manual disassembly, which is quite troublesome. Furthermore, since the internal activated carbon material is in a static state, the purification effect on formaldehyde in the air is poor, making it difficult to promote its use.

[0004] To address this problem, this application provides an air purification filter using a manganese-based catalyst nanofiber membrane, NanoCaptur, for decomposing formaldehyde. Utility Model Content

[0005] The purpose of this invention is to provide an air purification filter for a manganese-based catalyst nanofiber membrane, NanoCaptur, used for decomposing formaldehyde. This addresses the problems in the prior art where formaldehyde filtration methods rely on activated carbon adsorption, requiring frequent replacement of the activated carbon material after prolonged use, which is inconvenient. Furthermore, the activated carbon is often in a static state, resulting in poor formaldehyde purification and overall performance.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An air purification filter for decomposing formaldehyde using a manganese-based catalyst nanofiber membrane, NanoCaptur, includes an installation assembly and a filter membrane body. The installation assembly includes a mounting frame and a fixing frame, with the fixing frame disposed inside the mounting frame. The filter membrane body is disposed inside the installation assembly and is composed of a nanomembrane and a manganese-based catalyst layer uniformly loaded thereon, with the manganese-based catalyst layer disposed on one side of the nanomembrane.

[0007] A further improvement of this utility model is that: the mounting bracket has screws installed in its internal threads, and one end of the screws is movably connected to one side of the fixed frame.

[0008] A further improvement of this utility model is that: a second sealing gasket is provided inside the mounting bracket, and the second sealing gasket is located on one side of the fixed frame.

[0009] A further improvement of the present invention is that: the filter membrane body is disposed on the other side of the sealing gasket two, and the other side of the filter membrane body is provided with a sealing gasket one, which is disposed inside the mounting frame.

[0010] A further improvement of this utility model is that: an inlet surface is provided on one side of the filter membrane body, and an outlet surface is provided on the other side of the filter membrane body.

[0011] A further improvement of this utility model is that the manganese-based catalyst layer is disposed on the side of the nanofilm near the outlet surface, and an adhesive layer is disposed on both sides of the nanofilm.

[0012] A further improvement of this utility model is that an anti-ultraviolet layer is provided on the side of the nanofilm near the induction surface, and both the anti-ultraviolet layer and the manganese-based catalyst layer are provided on the other side of the adhesive layer.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. This utility model provides an air purification filter for decomposing formaldehyde using a manganese-based catalyst nanofiber membrane, NanoCaptur. Through the combined action of the nanofilm and the manganese-based catalyst layer, wherein the nanofilm is selected from one or more of polyacrylonitrile, polyethylene oxide, polyvinyl alcohol, or polyvinylidene fluoride, and the manganese-based catalyst layer is composed of manganese dioxide, formaldehyde is catalytically decomposed through the manganese-based catalyst layer. Simultaneously, the manganese-based catalyst layer acts as a catalyst and does not participate in the reaction. Even after prolonged use, the manganese-based catalyst layer will not decrease, significantly reducing the replacement frequency of the filter membrane and extending its service life.

[0014] 2. This utility model provides an air purification filter using a manganese-based catalyst nanofiber membrane, NanoCaptur, for decomposing formaldehyde. Through the combined action of the nanofilm and the manganese-based catalyst layer, air passes through the filter membrane body from the inlet surface and exits through the outlet surface. The manganese-based catalyst layer on the nanofilm catalyzes the decomposition of formaldehyde. During this process, the air is constantly moving, which increases the filtration efficiency and effect compared to activated carbon adsorption. Attached Figure Description

[0017] The present invention will be further described in detail below with reference to embodiments: like Figure 1-5 As shown, this utility model provides an air purification filter for a manganese-based catalyst nanofiber membrane NanoCaptur for decomposing formaldehyde, including an installation assembly 1 and a filter membrane body 20. The installation assembly 1 includes an installation frame 10 and a fixing frame 12. The fixing frame 12 is disposed inside the installation frame 10. A screw 11 is threaded inside the installation frame 10. One end of the screw 11 is movably connected to one side of the fixing frame 12. By turning the screw 11, the filter membrane body 20 is fixed inside the installation frame 10.

[0018] like Figure 1 and Figure 2 As shown, a second sealing gasket 13 is provided inside the mounting frame 10. The second sealing gasket 13 is located on one side of the fixed frame 12, and the filter membrane body 20 is located on the other side of the second sealing gasket 13. A first sealing gasket 14 is provided on the other side of the filter membrane body 20. The first sealing gasket 14 is located inside the mounting frame 10. The second sealing gasket 13 and the first sealing gasket 14 are pressed tightly against the fixed frame 12 by screws 11, so that they are in close contact with the filter membrane body 20 to prevent unfiltered air from passing through.

[0019] like Figure 2-5As shown, the filter membrane body 20 is disposed inside the mounting assembly 1. The filter membrane body 20 consists of a nanomembrane 23 and a manganese-based catalyst layer 26 uniformly loaded thereon. The manganese-based catalyst layer 26 is disposed on one side of the nanomembrane 23. An inlet surface 21 is disposed on one side of the filter membrane body 20, and an outlet surface 22 is disposed on the other side of the filter membrane body 20. The manganese-based catalyst layer 26 is disposed on the side of the nanomembrane 23 near the outlet surface 22. Air passes through the filter membrane body 20 through the inlet surface 21 and is discharged through the outlet surface 22. By covering the nanomembrane 23 with the manganese-based catalyst layer 26... 6. Formaldehyde is catalyzed by the manganese-based catalyst layer 26, causing it to decompose. At the same time, the manganese-based catalyst layer 26 does not participate in the reaction as a catalyst, and it will not decrease after long-term use. Through the combined action of the nano-membrane 23 and the manganese-based catalyst layer 26, the replacement frequency of the filter membrane body 20 is greatly reduced, and the service life of the filter membrane body 20 is increased. Meanwhile, during the process of formaldehyde catalysis by the manganese-based catalyst layer 26 on the nano-membrane 23, the air is constantly moving, which increases the filtration efficiency and filtration effect compared to the adsorption of activated carbon materials.

[0020] like Figure 5 As shown, adhesive layers 25 are provided on both sides of the nanomembrane 23. An anti-ultraviolet layer 24 is provided on the side of the nanomembrane 23 near the inlet surface 21. The anti-ultraviolet layer 24 prevents ultraviolet rays from oxidizing the nanomembrane 23 and increases the service life of the filter membrane body 20. The anti-ultraviolet layer 24 and the manganese-based catalyst layer 26 are both provided on the other side of the adhesive layer 25. The adhesive layer 25 fixes the anti-ultraviolet layer 24 and the manganese-based catalyst layer 26 to the nanomembrane 23.

[0021] The working principle of the NanoCaptur air purification filter, which uses a manganese-based catalyst nanofiber membrane to decompose formaldehyde, will be explained in detail below.

[0022] like Figure 1-5As shown, the nanomembrane 23 in the filter membrane body 20 is selected from one or more of polyacrylonitrile, polyethylene oxide, polyvinyl alcohol, or polyvinylidene fluoride. The manganese-based catalyst layer 26 is composed of manganese dioxide. When using the NanoCaptur air purification filter with manganese-based catalyst nanofiber membrane for formaldehyde decomposition, after placing the filter membrane body 20 in the mounting frame 10, the sealing gasket 13 and the fixing frame 12 are placed in, and the sealing gasket 13 is brought into contact with the filter membrane body 20. Then, the fixing frame 12 is tightened by the screws 11, so that both sides of the filter membrane body 20 are tightly fitted with the sealing gasket 14 and the sealing gasket 13, preventing unfiltered air from passing through the gaps. Then, it is placed in the purifier. Air enters through the inlet surface 21, passes through the filter membrane body 20, and exits through the outlet surface 22. A manganese-based catalyst layer 26 is coated on the nanomembrane 23, catalyzing the decomposition of formaldehyde. Simultaneously, the manganese-based catalyst layer 26 acts as a catalyst and does not participate in the reaction, and its density does not decrease over prolonged use. The combined effect of the nanomembrane 23 and the manganese-based catalyst layer 26 significantly reduces the replacement frequency of the filter membrane body 20, extending its lifespan. Furthermore, the continuous air movement during the catalytic process of formaldehyde removal by the manganese-based catalyst layer 26 on the nanomembrane 23 enhances filtration efficiency and effectiveness compared to activated carbon adsorption.

[0023] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
