Description

Technical Field

[0001] This utility model relates to the field of air purifier technology, and in particular to a nano-carbon fiber purification module. Background Technology

[0002] A circulating toxic gas purifier is a device used to treat toxic gases and can be widely used in industrial production, environmental protection, medical treatment, scientific research, and other fields. Existing circulating toxic gas purifiers typically include multiple functional modules such as air intake, purification, filtration, and exhaust. Specifically, the purification module adsorbs harmful gases and intercepts and adsorbs particulate matter in the air. For example, Chinese patent document CN208448836U discloses a first purification module and a second purification module using activated carbon as the adsorption and purification material. However, activated carbon has problems such as low adsorption capacity and its adsorption and purification effect is greatly affected by humidity. Therefore, existing purification modules using activated carbon as the adsorption and purification material suffer from low purification efficiency.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0004] The present invention provides a nano-carbon fiber purification module, which aims to solve the problem of low purification efficiency in purification modules that use activated carbon as an adsorption and purification material.

[0005] To achieve the above objectives, the solution provided by this utility model is as follows:

[0006] A nanofiber purification module includes a box with openings at the bottom and top; it also includes a support component and a modified nanofiber layer disposed within the box; the modified nanofiber layer is disposed on the support component and contacts the inner wall of the box, and the modified nanofiber layer is used to purify the air.

[0007] Optionally, the modified carbon nanofiber layer includes a nonwoven fabric wrapping layer and modified carbon nanofibers filled within the nonwoven fabric wrapping layer.

[0008] Optionally, the support component is a wave-shaped support mesh plate, and the modified carbon nanofiber layer is disposed on the support component in a wave-like form.

[0009] Optionally, the two sides of the support mesh plate are respectively provided with a plug-in part and a plug-in block. The plug-in block is provided with a plug-in groove that cooperates with the plug-in part. Two adjacent support mesh plates are spliced ​​together through the plug-in part and the plug-in block.

[0010] Optionally, a hook is formed between the plug-in portion and the support mesh plate; a support portion is provided below the plug-in block, the support portion is formed on one side of the support mesh plate, and the support portion is at the same height as the bottom of the support mesh plate.

[0011] Optionally, the inner wall of the box is provided with a support side plate for supporting the support mesh plate.

[0012] Optionally, the modified carbon nanofiber layer is disposed in the box in an inverted S-shape, and the modified carbon nanofiber layer has spaced-apart lower recesses and spaced-apart upper recesses, the upper recesses and lower recesses being arranged adjacent to each other; the support member is placed in the lower recesses and is used to support the modified carbon nanofiber layer, and a first airflow channel is formed between the support member and the modified carbon nanofiber layer.

[0013] Optionally, the supporting component is a vertically arranged first corrugated plate, and the cross-section of the first corrugated plate in the horizontal direction is wave-shaped.

[0014] Optionally, a second corrugated plate is vertically placed inside the upper recess; the cross-section of the second corrugated plate in the horizontal direction is wavy, and the crest of the second corrugation corresponds to the crest of the first corrugated plate to jointly clamp the modified carbon nanofiber layer.

[0015] Beneficial effects:

[0016] This invention provides a nanofiber purification module suitable for purifying one or more gases, such as radioactive gases, acidic gases, alkaline gases, hydrogen sulfide, and mercury vapor. The module features a support component within a box with openings at both the bottom and top, upon which a modified nanofiber layer is placed.

Furthermore, when used for extended periods in high humidity environments, the purification module maintains a more stable purification effect compared to activated carbon purification modules.

[0035] Please see Figure 1 , Figure 2 , Figure 8 as well as Figure 9 This utility model provides a nano-carbon fiber purification module, which can be used in a circulating toxic gas purifier, and includes a housing 1, a supporting component 2, and a modified nano-carbon fiber layer 3.

[0036] Specifically, the bottom and top of the housing 1 are provided with openings 101 to allow gas to enter the purification module for purification, and the purified gas can be discharged from the housing 1. The support component 2 is located inside the housing 1, and the modified carbon nanofiber layer 3 is placed on the support component 2. When the modified carbon nanofiber layer 3 is placed on the support component 2, it should be in contact with all the inner walls of the housing 1. This ensures that when the gas flows upward through the carbon nanofiber purification module, the gas can have maximum contact with the modified carbon nanofibers 32 in the modified carbon nanofiber layer 3. The modified carbon nanofibers 32 in the modified carbon nanofiber layer 3 have a large number of oxygen-containing functional groups that adsorb and purify gaseous pollutants, and can be used for the purification of toxic gas molecules, viruses, bacteria, and other gaseous pollutants. Compared to ordinary activated carbon, carbon nanofibers have an extremely well-developed microporous structure, with a specific surface area reaching 1000-2000 m². 2 / g, after modification of carbon nanofibers, the purification efficiency is high, at least an order of magnitude higher than that of ordinary granular activated carbon. Furthermore, during the activation process, different oxygen-containing groups are generated on the surface of the carbon nanofibers. Under the action of water, some groups can be oxidized to hydroxyl groups, increasing the surface redox capacity and making the carbon nanofibers suitable for high humidity environments, exhibiting excellent high humidity resistance. Moreover, the number of 2nm micropores suitable for adsorbing gaseous pollutants in carbon nanofibers of the same weight is more than 1000 times that of granular activated carbon, and its adsorption capacity is more than 10 times that of granular activated carbon. Therefore, when modified carbon nanofiber 32 is used as a purification adsorption material in a purification module, the purification module has high purification efficiency and can stably perform its purification function during long-term use in high humidity environments.

[0037] like Figure 2 As shown, optionally, the modified carbon nanofiber layer 3 includes a nonwoven fabric wrapping layer 31 and modified carbon nanofibers 32 filled within the nonwoven fabric wrapping layer 31. Since the modified carbon nanofibers 32 are brittle and easily break apart, in order to ensure that the modified carbon nanofibers 32 in the modified carbon nanofiber layer 3 can be stacked together in a concentrated manner and that the modified carbon nanofibers 32 can be used for gas purification, this embodiment utilizes nonwoven fabric to wrap the modified carbon nanofibers 32, allowing them to be stacked together to form the modified carbon nanofiber layer 3.

[0038] Moreover, because the nonwoven fabric has a porous structure, when the gas enters the purification module, the gas can flow into the modified carbon nanofiber layer 3 and come into contact with the modified carbon nanofiber 32.

[0039] like Figure 1 and Figure 3 As shown, optionally, the support component 2 is a corrugated support mesh plate, and the modified carbon nanofiber layer 3 is folded into a corrugated shape and placed on the support component 2 in a corrugated form. Specifically, the support mesh plate has vent holes (not shown in the attached figure) to ensure that gas can flow into the modified carbon nanofiber layer 3 through the vent holes. Compared with the modified carbon nanofiber layer 3 being laid flat on the housing 1, the modified carbon nanofiber layer 3 being placed on the support component 2 in a corrugated form allows for a larger area to be covered. Under the same air volume, the increased area of ​​the modified carbon nanofiber layer 3 reduces the air velocity flowing through the housing 1. With the reduced air velocity, the time it takes to pass through the modified carbon nanofiber layer 3 of the same thickness will be longer (more than 10 seconds), giving the gas more opportunities to come into contact with the modified carbon nanofiber 32 in the modified carbon nanofiber layer 3, thereby improving the adsorption and purification effect of the purification module on toxic gases, viruses, bacteria, etc.

[0040] like Figure 7As shown, it should be noted that the waveform shape of the supporting mesh can be, but is not limited to, triangular waveform, sine waveform, square waveform, etc.

[0041] like Figures 3 to 6 As shown, optionally, the two sides of the support mesh plate are respectively provided with a horizontal insertion part 4 and an insertion block 5. The insertion block 5 is provided with an insertion groove 51 that cooperates with the insertion part 4. Two adjacent support mesh plates are spliced ​​together through the insertion part 4 and the insertion block 5, thereby realizing the arrangement of modified carbon nanofiber layers 3 of different lengths to meet the needs of gas purification in different places.

[0042] like Figures 3 to 6 As shown, optionally, when the waveform of the supporting mesh plate is a triangular waveform, a hook is formed between the plug-in part 4 and the supporting mesh plate; a supporting part 6 is provided below the plug-in block 5, the supporting part 6 is formed on one side of the supporting mesh plate, and the supporting part 6 is at the same height as the bottom of the supporting mesh plate, such as... Figure 5 and Figure 6 As shown, when the insertion part 4 on one side of one support mesh plate is inserted into the insertion block 5 on another support mesh plate, the splicing and assembly of two adjacent support mesh plates can be achieved.

[0043] like Figure 1 As shown, optionally, the inner wall of the housing 1 is provided with a support side plate 7 for supporting the support mesh plate, and the support mesh plate can be fixed to the support side plate 7 by threaded connectors (such as screws). In order to fix the modified nano-carbon fiber layer 3 to the support mesh plate, the non-woven fabric wrapping layer 31 on the modified nano-carbon fiber layer 3 can be fixed to the support mesh plate by needle and thread sewing.

[0044] like Figures 8 to 12 As shown, optionally, this utility model also provides another implementation of the nanofiber purification module. Specifically, the modified nanofiber layer 3 is arranged in an inverted S-shape inside the housing 1, and the modified nanofiber layer 3 has spaced-apart lower recesses 3b and spaced-apart upper recesses 3a, the upper recesses 3a and lower recesses 3b being arranged adjacent to each other; the support member 2 is placed inside the lower recesses 3b and is used to support the modified nanofiber layer 3, and a first airflow channel 3c is formed between the support member 2 and the modified nanofiber layer 3, thereby allowing gas to pass through. The gas can flow into the modified carbon nanofiber layer 3 through the first airflow channel 3c, or it can flow directly into the modified carbon nanofiber layer 3. Moreover, compared to the modified carbon nanofiber layer 3 being laid flat in the box 1, the modified carbon nanofiber layer 3 is arranged in an inverted S-shape in the box 1, which increases the laying area of ​​the modified carbon nanofiber layer 3 by several times. This reduces the gas velocity passing through the modified carbon nanofiber layer 3 and increases the reaction time between the gas and the modified carbon nanofiber 32, thereby improving the adsorption and purification effect of the purification module on toxic gases, viruses, bacteria, etc.

[0045] Furthermore, when the support component 2 is placed inside the recess 3b and forms a first airflow channel 3c between it and the modified carbon nanofiber layer 3, the gas will be evenly distributed in different channels during the flow process, avoiding the problem of insufficient gas purification caused by the airflow being concentrated in certain areas.

[0046] like Figures 10 to 12 As shown, optionally, the support component 2 is a vertically arranged first corrugated plate, the cross-section of the first corrugated plate in the horizontal direction being wave-shaped. Using a corrugated plate as the support component 2 not only supports the modified carbon nanofiber layer 3, but also allows for the formation of complex first airflow channels 3c between the corrugated plate and the modified carbon nanofiber layer 3.

[0047] like Figure 8 , Figure 11 as well as Figure 12 As shown, optionally, a second corrugated plate 8 is vertically placed in the upper recess 3a (both the first corrugated plate and the second corrugated plate 8 can be connected to the inner wall of the housing 1 through threaded connectors); the second corrugated plate 8 has a wave-shaped cross section in the horizontal direction, and a second airflow channel 3d is formed between the second corrugated plate 8 and the modified carbon nanofiber layer 3. The crest of the second corrugated plate 8 corresponds to the crest of the first corrugated plate to jointly clamp the modified carbon nanofiber layer 3, so that the modified carbon nanofiber layer 3 can maintain an inverted S-shaped form and will not deform or wrinkle. Thus, after the gas is purified, the gas can flow out of the modified carbon nanofiber layer 3 smoothly.

[0048] The design of the second airflow channel 3d makes the airflow path more complex and tortuous, allowing for a longer contact time between the air and the modified carbon nanofiber 32.

[0049] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
