[0037] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0038] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.
[0039] Hereinafter, with reference to the accompanying drawings, a purification component 100 according to a first aspect embodiment of the present invention will be described.
[0040] like Figures 1-3As shown, the purification component 100 may include: a housing 1 and a breathable membrane tube 2. The housing 1 has a first chamber 101 inside. The housing 1 has multiple sets of air holes corresponding to the first chamber 101. Each set of air holes includes an air inlet 111 and an air outlet 121. There are multiple breathable membrane tubes 2 and they are located in the first chamber 101. Each breathable membrane tube 2 is respectively set with a set of air holes. The two ends of each breathable membrane tube 2 are respectively connected to the air inlet 111 and the air outlet 121 of the corresponding set. The airflow outside the housing 1 is suitable to enter the corresponding breathable membrane tube 2 through each air inlet 111 and exit the housing 1 through the corresponding air outlet 121.
[0041] In other words, the multiple sets of air holes on the box body 1 are set one-to-one with the multiple breathable membrane tubes 2 inside the box body 1. One end of each breathable membrane tube 2 is connected to the corresponding set of air inlet 111, and the other end is connected to the corresponding set of air outlet 121. Thus, the air outside the box body 1 can enter the multiple breathable membrane tubes 2 through the multiple air inlet 111, and be discharged to the outside of the box body 1 through the multiple air outlets 121 along the multiple breathable membrane tubes 2.
[0042] like Figures 1-3 As shown, the purification component 100 also includes a liquid supply device, which is adapted to supply odor-absorbing liquid 7 to the first chamber 101. Specifically, the breathable membrane tube 2 defines a liquid space located outside the breathable membrane tube 2 within the first chamber 101. The liquid supply device is adapted to supply odor-absorbing liquid 7 to the first chamber 101 so that the odor-absorbing liquid 7 fills the liquid space. Thus, the liquid space can be filled with odor-absorbing liquid 7 through the liquid supply device. The odor-absorbing liquid 7 surrounds each breathable membrane tube 2. In this way, the airflow flowing through the breathable membrane tube 2 can be purified by membrane absorption, achieving the purification effect.
[0043] Understandably, "membrane absorption method" refers to a process where the gas and odor-absorbing liquid 7 are blocked from direct contact by a breathable membrane, and the two flow on opposite sides of the membrane. The breathable membrane has micropores, which are not selective in themselves but only serve to isolate the gas from the odor-absorbing liquid 7. The micropores on the breathable membrane are large enough that, theoretically, gas molecules separated on one side of the membrane can pass through the micropores to the other side of the membrane without very high pressure. This process mainly relies on the selective absorption of the odor-absorbing liquid 7 on the other side of the membrane to achieve the purpose of separating certain components in the mixed gas.
[0044] Specifically, the purification component 100 according to an embodiment of the present invention is used in an air handling device. The specific type of air handling device is not limited, such as air purifiers, air conditioners, humidifiers, etc. During the operation of these air handling devices, airflow will circulate, thereby performing related processing on the airflow, such as heating, cooling, purification, humidification, etc.
[0045] When the air handling equipment is equipped with the purification component 100 according to the embodiment of the present invention, the purification component 100 is located on the airflow path of the air handling equipment. When the air handling equipment is working, the airflow will flow through the purification component 100. Specifically, the airflow can enter the multiple breathable membrane tubes 2 in the first chamber 101 through the multiple air inlets 111 openly provided on the housing 1. The airflow entering the multiple breathable membrane tubes 2 can be separated by the odor absorption liquid 7 located outside the breathable membrane tubes 2 in the first chamber 101, thereby achieving the effect of purifying the airflow. The purified airflow can flow out through the multiple air outlets 121 openly provided on the housing 1 and be returned to the environment.
[0046] Therefore, the purification component 100 according to this embodiment of the invention employs membrane absorption. Air flows through the inside of the breathable membrane tube 2, while the odor-absorbing liquid 7 flows through the outside of the breathable membrane tube 2. Odors in the air can be removed by the absorbent liquid, and the absorbent liquid will not be carried away by the airflow, thus avoiding the risk of cross-contamination. Furthermore, it has relatively low environmental requirements during application and can effectively achieve the effect of air odor removal. Because there are multiple breathable membrane tubes 2, the effective area of the absorbent liquid is increased, thereby improving the purification effect.
[0047] Compared to related technologies, purification methods using adsorbents such as activated carbon are less prone to saturation, reducing replacement costs and the risk of secondary release. Compared to related technologies, degradation methods such as photocatalysis and DBD low-temperature plasma catalysis can achieve broad-spectrum removal of various odors by adjusting the composition of the odor absorption liquid 7, with low energy consumption and high removal efficiency. Compared to related technologies, purification methods using spray technology avoid the risk of cross-contamination caused by the wash liquid being easily carried out by the airflow, resulting in relatively high removal efficiency.
[0048] It should be noted that the composition of the odor-absorbing liquid 7 according to embodiments of the present invention is not limited, and can be specifically designed according to the air purification target. The applicant has found that air handling equipment is generally used for purifying indoor air, and the presence of odors in indoor air is one of the main purposes of purification. Based on this, the applicant has found that by designing the components of the odor-absorbing liquid 7, the odor-absorbing liquid 7 can be formed into an odor-removing liquid 7, thereby achieving a more effective odor removal effect.
[0049] For example, in some embodiments of the present invention, the odor-absorbing liquid 7 includes an acid-base buffer. This allows for the purification of odors in the airflow passing through the breathable membrane tube 2, effectively removing odors. Thus, the air handling equipment possesses odor-removing capabilities.
[0050] It should be noted that acid-base buffers are used to help capture odor molecules in the air that exhibit certain acidity or alkalinity, thereby achieving an effective odor purification effect. For example, in some embodiments, the acid-base buffer may include one or more of citric acid-sodium citrate, tartaric acid-sodium tartrate, NaOH-citric acid, NaOH-amino acids, etc., at a concentration of 0.5%-5% (i.e., the mass content of the acid-base buffer in the odor absorption liquid 7), thereby achieving a relatively effective and comprehensive odor removal effect.
[0051] Furthermore, the odor-absorbing liquid 7 may also include at least one of organic supramolecular components, metal ions, nanocatalysts, and hydrogen peroxide. This further optimizes the odor-removing function.
[0052] It should be noted that the organic supramolecular molecules used can effectively encapsulate the absorbed odor molecules, effectively preventing odor escape. For example, in some embodiments, the organic supramolecular molecules may include one or more of the following: cyclodextrin, cyclodextrin derivatives, dendritic macromolecules, stable microemulsion micelles, small molecule peptides, etc., at a concentration of 0.05%-2% (i.e., the mass content of organic supramolecular molecules in odor absorption liquid 7), thereby effectively encapsulating the absorbed odor molecules and effectively preventing odor escape.
[0053] It should be noted that the metal ions used can be used to form bonds and capture odors rich in N, S, carbonyl, carboxyl, aldehyde, etc., and can synergize with hydrogen peroxide to oxidize and degrade odors. For example, in some embodiments, the metal ions may include Ag. + Cu 2+ Fe 3+ Zn 2+ Mn 2+ One or more of these, at a concentration of 0.01%-0.5% (i.e., the mass content of metal ions in odor absorption liquid 7), can effectively capture odors rich in N, S, carbonyl, carboxyl, aldehyde and other elements by forming bonds, and can work synergistically with hydrogen peroxide to oxidize and degrade them, thereby improving the odor removal effect.
[0054] It should be noted that the nanocatalyst used can effectively adsorb and catalytically degrade odors in the odor absorption liquid 7, thereby improving the odor removal effect. For example, in some embodiments, the nanocatalyst may include one or more of nano titanium dioxide, nano zinc oxide, and their supported microparticles, with a solid content of 0%-1% (i.e., the mass content of the nanocatalyst in the odor absorption liquid 7), thereby effectively adsorbing and catalytically degrading odors in the odor absorption liquid 7 and improving the odor removal effect.
[0055] It should be noted that the hydrogen peroxide used can be used to effectively oxidize and degrade reducing odors, thereby improving the odor removal effect. For example, a concentration of 0%-5% (i.e., the mass content of hydrogen peroxide in odor absorption liquid 7) can effectively oxidize and degrade reducing odors.
[0056] For example, in some embodiments of the present invention, the odor-absorbing liquid 7 may be based on water and surfactants. It should be noted that the surfactants used can assist in capturing non-polar or weakly polar odor molecules in the air, thereby improving the odor removal effect. For example, in some embodiments, the surfactants may include: green surfactants such as polymeric amino acids, polymeric alkyl glycosides, and polyethers, at a concentration of 0.01%-0.5% (i.e., the mass content of the surfactant in the odor-absorbing liquid 7), thereby assisting in capturing non-polar or weakly polar odor molecules in the air and improving the odor removal effect.
[0057] In summary, in some embodiments of the present invention, the odor-absorbing liquid 7 can be based on water and surfactants, mixed with acid-base buffers, and at least one of metal ions, organic supramolecular molecules, nanocatalysts, hydrogen peroxide, etc., thereby achieving a more effective odor removal effect. Therefore, the purification component 100 according to embodiments of the present invention can be widely used in air handling equipment such as air conditioners and air purifiers, achieving a removal rate of over 99% for common indoor odor pollutants such as formaldehyde, trimethylamine, ammonia, and toluene, demonstrating excellent odor removal performance.
[0058] In some embodiments of the present invention, such as Figures 1-3 As shown, the housing 1 includes a first wall 11 and a second wall 12. The first wall 11 and the second wall 12 are arranged opposite to each other and spaced apart. For example, the first wall 11 and the second wall 12 are arranged opposite to each other and spaced apart in the vertical direction. In this case, the first wall 11 can be located above or below the second wall 12. For another example, the first wall 11 and the second wall 12 are arranged opposite to each other and spaced apart in the front-back direction. In this case, the first wall 11 can be located on the rear side or the front side of the second wall 12. For yet another example, the first wall 11 and the second wall 12 are arranged opposite to each other and spaced apart in the left-right direction. In this case, the first wall 11 can be located on the left side or the right side of the second wall 12.
[0059] like Figures 1-3As shown, the first chamber 101 is located between the first wall surface 11 and the second wall surface 12. All air inlets 111 are located on the first wall surface 11, and all air outlets 121 are located on the second wall surface 12. Therefore, airflow from outside the housing 1 can enter the housing 1 through the air inlets 111 on the first wall surface 11 and then flow out through the air outlets 121 on the second wall surface 12. This simplifies the airflow path, reduces wind resistance, and improves the efficiency of airflow through the purification component 100, thereby increasing purification efficiency. Furthermore, it simplifies the extension direction of the breathable membrane tube 2, simplifies the processing of the breathable membrane tube 2, and reduces problems such as mutual interference caused by different extension directions of the breathable membrane tube 2.
[0060] Of course, the present invention is not limited to this. For example, in other embodiments of the present invention, air inlets 111 can be provided on both walls of the housing 1. For example, air inlets 111 can be provided on both the rear wall and the upper wall of the housing 1, and air outlets 121 can be provided on the front wall of the housing 1. The sum of the number of air inlets 111 on the rear wall and the upper wall is equal to the number of air outlets 121 on the front wall. In this case, some breathable membrane tubes 2 can extend from the air inlets 111 on the rear wall to the air outlets 121 on the front wall, and some other breathable membrane tubes 2 can extend from the air inlets 111 on the upper wall to the air outlets 121 on the front wall. This will not be elaborated here.
[0061] Optionally, such as Figures 1-3 As shown, the first wall 11 and the second wall 12 can be arranged in parallel. This minimizes the size of the housing 1 and reduces the space it occupies. However, the invention is not limited to this; in other embodiments, the first wall 11 and the second wall 12 can be arranged non-parallel, for example, they can intersect at an acute angle.
[0062] In some embodiments, such as Figures 1-3As shown, when the housing 1 includes a first wall 11 and a second wall 12 that are opposite to and spaced apart, with all air inlets 111 located on the first wall 11 and all air outlets 121 located on the second wall 12, the centerline of the breathable membrane tube 2 can extend in a straight line, and the centerline of the breathable membrane tube 2 can be perpendicular to the first wall 11, or the centerline of the breathable membrane tube 2 can be perpendicular to the second wall 12. Alternatively, when the first wall 11 and the second wall 12 are arranged in parallel, the centerline of the breathable membrane tube 2 is perpendicular to both the first wall 11 and the second wall 12. This simplifies the extension direction of the breathable membrane tube 2, simplifies its processing, and avoids interference caused by different extension directions. It also simplifies the airflow path, allowing the airflow to flow in a straight line through the breathable membrane tube 2, effectively reducing wind resistance and further improving the efficiency of airflow through the purification component 100, thereby improving purification efficiency. Of course, the present invention is not limited to this. In other embodiments of the present invention, the center line of the breathable membrane tube 2 may also extend along curves, broken lines, etc., which will not be elaborated here.
[0063] Optionally, such as Figures 1-3 As shown, all the air inlets 111 are arranged in multiple rows and columns on the first wall surface 11. This arrangement of the air inlets 111 improves the space utilization of the first wall surface 11, thereby increasing the opening ratio of the air inlets 111 on the first wall surface 11, improving air intake efficiency, and ultimately improving purification efficiency. Optionally, all the air outlets 121 are arranged in multiple rows and columns on the second wall surface 12. This arrangement of the air outlets 121 improves the space utilization of the second wall surface 12, thereby increasing the opening ratio of the air outlets 121 on the second wall surface 12, improving air exhaust efficiency, and ultimately improving purification efficiency. Of course, the invention is not limited to this; all the air inlets 111 can also be arranged radially or in a pattern on the first wall surface 11, and all the air outlets 121 can also be arranged radially or in a pattern on the second wall surface 12, which will not be elaborated here.
[0064] Furthermore, it is worth noting that the number of breathable membrane tubes 2 is not limited, for example, it can be 1000 to 10000 tubes, etc. In addition, in order to improve the installation stability of the breathable membrane tubes 2 and prevent the odor absorption liquid 7 from leaking from the connection between the breathable membrane tubes 2 and the box body 1, a sealing structure can be set at the connection between the breathable membrane tubes 2 and the box body 1. For example, in some embodiments, the seal can be achieved by glue sealing, that is, after the breathable membrane tubes 2 are installed, glue is poured into the connection between the box body 1 and the breathable membrane tubes 2 to obtain a cured glue seal structure 5.
[0065] Optionally, all breathable membrane tubes 2 can have the same specifications, thus facilitating processing and production. Optionally, all air inlets 111 can have the same shape and size, thus facilitating processing. Optionally, all air outlets 121 can have the same shape and size, thus facilitating processing. Optionally, all air inlets 111 and air outlets 121 can have the same shape and size, and the shape and size of air inlets 111 and air outlets 121 can be the same, thus facilitating processing. Of course, the present invention is not limited to this. In other embodiments of the present invention, at least two air inlets 111 can also have different shapes and sizes, at least two air outlets 121 can also have different shapes and sizes, at least two breathable membrane tubes 2 can also have different shapes and sizes, etc., which will not be elaborated here.
[0066] It is worth noting that the specific parameters of the breathable membrane tube 2 can be designed according to the specific goal of air purification. For example, when the purification component 100 is used in an air handling device to purify odors in indoor air, the breathable membrane tube 2 can be set to meet at least one of the following conditions, so as to effectively ensure the smooth flow of air, reduce the ventilation resistance caused by the purification component 100, and achieve a more effective purification effect.
[0067] Condition 1: The wall thickness of the breathable membrane tube 2 is 8μm-1000μm, for example, 8μm, 80μm, 180μm, 280μm, 380μm, 480μm, 580μm, 680μm, 780μm, 880μm, 980μm, 1000μm, etc.
[0068] Condition 2: The outer diameter of the breathable membrane tube 2 is 0.5mm-10mm, for example, 0.5mm, 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, etc.
[0069] Condition 3: The air permeability of the breathable membrane tube 2 is 0.1 L / min / cm. 2 -5L / min / cm 2 For example, 0.1 L / min / cm 2 1L / min / cm 2 2L / min / cm 2 3L / min / cm 2 4L / min / cm 2 5L / min / cm 2 Wait a minute. It should be noted that the air permeability of the breathable membrane tube 2 is the result of the test at 7 kPa.
[0070] Condition 4: The water permeability resistance of the breathable membrane tube 2 is 40kPa-400kPa, for example, 40kPa, 100kPa, 200kPa, 300kPa, 400kPa, etc.
[0071] Condition 5: The sum of the outer surfaces of all breathable membrane tubes 2 is 0.1m. 2 -3m 2 Thus, the contact area between the entire breathable membrane tube 2 and the odor-absorbing liquid 7 can be approximately 0.1m². 2 -3m 2 For example, 0.1m 2 0.5m 2 1m 2 1.5m 2 2m 2 2.5m 2 3m 2 etc.
[0072] Condition 6: The axial length of the breathable membrane tube 2 is 30mm-50mm, so that when the breathable membrane tube 2 extends along the thickness direction of the box body 1, the wall thickness of the box body 1 is approximately 30mm-50mm. For example, 30mm, 35mm, 40mm, 45mm, 50mm, etc.
[0073] Furthermore, in the purification component 100 according to the present invention, the material of the breathable membrane tube 2 is not limited. For example, it can be one or a combination of inorganic porous ceramics, foam metal, organic polymers PTFE (polytetrafluoroethylene), TPU (thermoplastic polyurethane elastomer), PAN polyacrylonitrile, PVC polyvinyl chloride, PES polyethersulfone, PP polypropylene, PS polysulfone, and PVDF polyvinylidene fluoride, thereby achieving a more effective membrane absorption purification effect for indoor air.
[0074] In some embodiments of the present invention, such as Figures 1-3As shown, the housing 1 also has a second chamber 102, and the housing 1 also has a corresponding liquid injection port 1021 for the second chamber 102. That is, the liquid injection port 1021 is connected to the second chamber 102, so that odor-absorbing liquid 7 can be injected into the second chamber 102 through the liquid injection port 1021. The liquid supply device is adapted to draw odor-absorbing liquid 7 from the second chamber 102, so that the liquid supply device can draw odor-absorbing liquid 7 from the second chamber 102 and supply it to the first chamber 101. Thus, by simultaneously setting the first chamber 101 and the second chamber 102 in the housing 1, the housing 1 has a high degree of integration. It has both the second chamber 102, which provides a liquid storage environment, and the first chamber 101, which provides a purification environment. Therefore, the purification component 100 has a compact, small, simple, and highly modular structure, can be installed as a whole, and is convenient to use. Of course, the present invention is not limited to this. In other embodiments of the present invention, a second chamber 102 may be provided outside the box 1 to store odor-absorbing liquid 7, etc., which will not be elaborated here.
[0075] Furthermore, such as Figures 1-3 As shown, the first chamber 101 has a liquid inlet 1011. The liquid supply device is located outside the first chamber 101 and supplies odor-absorbing liquid 7 to the first chamber 101 through the liquid inlet 1011. The first chamber 101 also has a liquid outlet 1012. The liquid outlet 1012 is set higher than the liquid inlet 1011 and is connected to the second chamber 102. Therefore, during the operation of the liquid supply device, the odor absorption liquid 7 can be circulated. Specifically, during the operation of the liquid supply device, the odor absorption liquid 7 can be drawn from the second chamber 102 and then supplied to the first chamber 101 through the liquid inlet 1011. When the odor absorption liquid 7 in the first chamber 101 rises to the height of the liquid outlet 1012, it can overflow from the liquid outlet 1012 and flow back to the second chamber 102. In this cycle, the odor absorption liquid 7 in the first chamber 101 can be circulated, thereby disturbing the odor absorption liquid 7 in the first chamber 101 and avoiding problems such as saturation of the odor absorption liquid 7. As a result, the odor absorption liquid 7 can play a more thorough and effective purification role in the airflow flowing in the breathable membrane tube 2.
[0076] Furthermore, since the odor-absorbing liquid 7 discharged from the first chamber 101 returns to the second chamber 102, energy can be saved, the odor-absorbing liquid 7 can be fully utilized, and the liquid supply device can be simplified, thus simplifying the overall structure of the purification component 100. Of course, the present invention is not limited to this. In other embodiments of the present invention, the odor-absorbing liquid 7 overflowing from the drain port 1012 can also flow to other chambers, and then, through an additional liquid guiding structure, the liquid from the other chambers can be injected into the second chamber 102, etc., which will not be elaborated here.
[0077] Optionally, such as Figures 1-3As shown, the height direction of the first chamber 101 is vertical, and the length and width directions of the first chamber 101 are perpendicular to the height direction. When the second chamber 102 is located on one side of the length of the first chamber 101, the inlet 1011 and outlet 1012 can be located on the same side of the length of the first chamber 101, i.e., closer to the second chamber 102, thereby simplifying the configuration of the liquid supply device.
[0078] In addition, besides being positioned higher than the inlet 1011, the drain port 1012 also has other features such as... Figures 1-3 As shown, when both the inlet 1011 and the outlet 1012 are pipe openings, the outlet 1012 and the inlet 1011 can also be positioned close to both sides of the width of the first chamber 101, thereby improving the circulation disturbance effect. Of course, the invention is not limited to this; the outlet 1012 may not be a pipe opening, for example, in… Figures 4-5 In the illustrated embodiment, the drain outlet 1012 can also be an elongated overflow outlet extending along the width direction of the first chamber 101, which is not limited here. In addition, in some embodiments, when the drain outlet 1012 is in the form of a pipe, a drain pipe 6 can be inserted through the drain outlet 1012.
[0079] Furthermore, depending on the application scenario of the purification component 100, the positions of the air inlet 111 and air outlet 121 relative to the first chamber 101 can be set as needed. For example, in... Figures 1-3 In the first embodiment shown, the first wall surface 11 and the second wall surface 12 can be the two side walls of the first chamber 101, i.e., the upper wall surface and the lower wall surface. The air inlet 111 is located on the upper wall surface of the first chamber 101, and the air outlet 121 is located on the lower wall surface of the first chamber 101. The odor-absorbing liquid 7 is injected into the first chamber 101 from bottom to top, and the airflow passes from top to bottom through the breathable membrane tube 2 inside the first chamber 101. For example, in... Figures 4-5 In the second embodiment shown, the first wall surface 11 and the second wall surface 12 can be the two side walls of the width of the first chamber 101, namely the rear wall surface and the front wall surface. The air inlet 111 is located on the rear wall surface of the first chamber 101, and the air outlet 121 is located on the front wall surface of the first chamber 101. The odor-absorbing liquid 7 is injected into the first chamber 101 from bottom to top, and the airflow passes through the breathable membrane tube 2 inside the first chamber 101 from front to back. Etc., will not be elaborated here.
[0080] like Figures 1-3As shown, in some embodiments, the housing 1 also has a third chamber 103, which is located on the same side as the second chamber 102, such as on the same side of the length of the first chamber 101. This reduces the distance between the liquid supply device and the first chamber 101 and the second chamber 102, thereby simplifying the liquid supply device and shortening the extraction or supply path of the odor absorption liquid 7, thus reducing energy consumption. The liquid supply device may include a micro liquid pump 31 located in the third chamber 103. The micro liquid pump 31 is connected to the second chamber 102 via a liquid extraction pipe 32 and to the first chamber 101 via a liquid supply pipe 33. In other words, the liquid supply device may include a micro liquid pump 31, a liquid extraction pipe 32, and a liquid supply pipe 33. The first chamber 101 has a liquid inlet 1011, and the second chamber 102 has a liquid extraction port 1022. The liquid extraction pipe 32 is connected to the inlet of the micro liquid pump 31 and passes through or is connected to the liquid extraction port 1022. The liquid supply pipe 33 is connected to the outlet of the micro liquid pump 31 and passes through or is connected to the liquid inlet 1011, thereby achieving a simple and effective connection. For example, when the micro liquid pump 31 is working, the odor absorption liquid 7 in the second chamber 102 is drawn into the micro liquid pump 31 through the liquid extraction pipe 32 and flows through the liquid supply pipe 33 into the first chamber 101. After the injected amount exceeds a certain amount, the excess odor absorption liquid 7 flows back to the second chamber 102 through the liquid outlet 1012.
[0081] Therefore, by installing the micro-liquid pump 31 in a third chamber 103, independent of the first chamber 101 and the second chamber 102, within the housing 1, the micro-liquid pump 31 can be protected, facilitating its installation and maintenance. Furthermore, the housing 1 has a high degree of integration, making overall installation convenient. Of course, the invention is not limited to this. In other embodiments, the micro-liquid pump 31 can be located outside the housing 1, or within one of the first chamber 101 and the second chamber 102, for example, 4 and... Figure 5 As shown, the micro liquid pump 31 can be directly installed in the second chamber 102, thus eliminating the need for the liquid extraction tube 32, which will not be described in detail here.
[0082] It is worth noting that the purification component 100 according to the embodiments of the present invention is used in an air handling device, which is generally used for treating indoor air. Therefore, a miniature liquid pump 31 can be selected. For example, in some optional examples, the miniature liquid pump 31 can be a corrosion-resistant pump with a flow rate of 0.01L / min-1L / min, thereby meeting the circulation of a small flow rate of odor absorption liquid 7, reducing energy consumption, and achieving a more effective purification effect.
[0083] In some embodiments of the present invention, a switch cover 4 may be provided at the injection port 1021, which is used to open and close the injection port 1021. Thus, when it is not necessary to inject the odor-absorbing liquid 7, the switch cover 4 can be used to seal the injection port 1021, thereby preventing the odor-absorbing liquid 7 from leaking out of the injection port 1021. When it is necessary to inject the odor-absorbing liquid 7, or when it is necessary to pour out the odor-absorbing liquid 7, the switch cover 4 can be used to open the injection port 1021, thereby facilitating the injection of the odor-absorbing liquid 7 outside the box 1 into the injection port 1021, or the pouring out of the odor-absorbing liquid 7 inside the box 1 from the injection port 1021.
[0084] The purification component 100 according to embodiments of the present invention can also be cleaned. For example, in some embodiments, when the purification component 100 needs to be cleaned, the micro liquid pump 31 can be de-energized. For example, when the micro liquid pump 31 is connected to an external control board via control line 34, the connection between control line 34 and the external control board can be disconnected, and the purification component 100 can be rotated so that the drain port 1012 of the first chamber 101 faces downward, so that the liquid in the first chamber 101 can flow out completely from the drain port 1012 into the second chamber 102. At the same time, the switch cover 4 is opened to allow the liquid to flow back into the second chamber 102. Odor-absorbing liquid 7 is poured out from the injection port 1021, for example, into a collection bucket or tank, so that the odor-absorbing liquid 7 that has been used in the first chamber 101 for a period of time can be poured out. Then, the breathable membrane tube 2 is cleaned with cleaning liquid. After cleaning, the purification component 100 can be reused. For example, fresh odor-absorbing liquid 7 can be injected into the second chamber 102 through the injection port 1021, and then the micro liquid pump 31 is turned on to pump the odor-absorbing liquid 7 in the second chamber 102 into the first chamber 101, etc.
[0085] It is worth noting that the above cleaning can employ at least one of forward cleaning and reverse cleaning. Forward cleaning involves using a cleaning liquid instead of the odor-absorbing liquid 7. The cleaning liquid is injected into the second chamber 102 through the injection port 1021, and then the micro-liquid pump 31 is turned on to pump the cleaning liquid from the second chamber 102 into the first chamber 101, allowing the cleaning liquid to circulate in the first chamber 101 and achieve forward cleaning of the breathable membrane tube 2. After cleaning, the cleaning liquid is poured out. Reverse cleaning involves using a cleaning liquid instead of airflow, allowing the cleaning liquid to flow in from the air inlet 111 and out from the air outlet 121, achieving reverse cleaning from the inside of the breathable membrane tube 2. Furthermore, it is worth noting that the specific choice of cleaning liquid is not limited; for example, it can be clean water.
[0086] In some embodiments of the present invention, the material of the housing 1 is not limited. For example, some corrosion-resistant plastics, glass, and metals, such as stainless steel, can be selected to improve the service life and reliability of the housing 1, and to provide more reliable protection for internal components, such as the breathable membrane tube 2 and the micro liquid pump 31, thereby improving the overall working reliability of the purification component 100.
[0087] It is worth noting that the first chamber 101 and the second chamber 102 can be separated by a first partition 13, on which a drain port 1012 connecting the first chamber 101 and the second chamber 102 can be provided. The second chamber 102 and the third chamber 103 can be separated by a second partition 14, on which a suction port 1022 can be provided. The third chamber 103 and the first chamber 101 can be separated by a third partition 15, on which a liquid inlet 1011 can be provided. Optionally, the first partition 13 and the third partition 15 can be different parts of the same partition.
[0088] An air handling apparatus according to a second aspect of the present invention will now be described.
[0089] In embodiments of the present invention, the air handling equipment may include: an equipment body and a purification component 100. The equipment body includes an air inlet, an air outlet, and an air duct connecting the air inlet and the air outlet. The purification component 100 is a purification component 100 for an air handling equipment according to a first aspect embodiment of the present invention, and the purification component 100 is provided at least at one of the air inlet, the air outlet, and the air duct. Thus, the air is purified by the membrane absorption method of the purification component 100, so that the odor absorption liquid 7 is not carried away by the airflow, eliminating the risk of cross-contamination. Furthermore, because there are multiple breathable membrane tubes 2, the effective area of the gas and liquid is increased, thereby improving the purification effect.
[0090] In some embodiments of the present invention, combined with Figures 1-3 The air handling unit has an air inlet at the top, a purification component 100 is located at the air inlet, an air intake 111 is located on the upper surface of the housing 1, and an air outlet 121 is located on the lower surface of the housing 1. Therefore, when airflow flows from top to bottom towards the air inlet (e.g., Figure 1 (The direction indicated by the middle arrow A) allows air to flow from top to bottom through the housing 1, thus conforming to the airflow direction and enabling the purification component 100 to effectively perform its purification function. Furthermore, in this embodiment, the top and bottom direction can be the thickness direction of the housing 1, thereby minimizing the path of airflow through the housing 1, reducing wind resistance, and improving purification efficiency.
[0091] In some embodiments of the present invention, combined with Figures 4-5 An air inlet is located at the rear of the air handling unit, and the purification component 100 is positioned at the air inlet. An air intake vent 111 is located on the rear surface of the housing 1, and an air outlet 121 is located on the front surface of the housing 1. Therefore, when airflow moves from rear to front towards the air inlet (e.g., ...), ... Figure 5(As indicated by the middle arrow B), the airflow can pass from back to front through the housing 1, thus conforming to the airflow direction and enabling the purification component 100 to effectively perform its purification function. Furthermore, in this embodiment, the front-to-back direction can be the thickness direction of the housing 1, thereby minimizing the path of the airflow through the housing 1, reducing wind resistance, and improving purification efficiency.
[0092] Of course, the present invention is not limited to this. For example, in other embodiments of the present invention, the purification component 100 may be disposed at the air outlet or in the air duct, which will not be elaborated here.
[0093] Optionally, in some embodiments, the purification component 100 is detachable from the air conditioner. For example, the purification component 100 is detachably located at the air inlet or air outlet, thereby facilitating the maintenance, cleaning, replacement, etc. of the purification component 100. When the purification component 100 is not required, it can also be removed.
[0094] Specifically, the type of air handling equipment according to embodiments of the present invention is not limited, and may include, for example, air purifiers, air conditioners, humidifiers, etc. During operation, these air handling devices all involve airflow, thereby performing related processing on the airflow, such as heating, cooling, purification, humidification, etc. Once the type of air handling equipment is determined, other components and operations of the air handling equipment according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
[0095] In some optional embodiments of the present invention, the air handling device is an air conditioner, and the air conditioner includes a heat exchanger disposed in an air duct, with the purification component 100 disposed at the air inlet. Thus, the air conditioner not only has the function of regulating air temperature, but also purifies the air using the purification component 100. Distributing the purification component 100 at the air inlet ensures that the air entering the air conditioner is relatively clean, thereby improving the air cleanliness of the air conditioner.
[0096] In some optional examples of the present invention, the air handling device is an air purifier, which may only have the purification component 100 according to the embodiments of the present invention; or, the air purifier may have other types of purification modules in addition to the purification component 100 according to the embodiments of the present invention, thereby meeting different design and usage requirements.
[0097] With economic and technological development, social progress, and rising living standards, interior decoration has become increasingly popular, with countless and diverse building materials and a wide range of additives being used. Newly renovated rooms often have a pungent odor; prolonged exposure can cause adverse reactions such as dizziness, eye irritation, sore throat, and chest tightness, primarily caused by formaldehyde and VOCs (volatile organic compounds). Furthermore, odors from cooking, smoking, and bathrooms also affect residents' quality of life, making indoor air purification a necessity for families in the post-pandemic era.
[0098] For odor removal, traditional methods often employ adsorbents such as activated carbon. However, due to the diverse nature of odors in the home environment and their extremely low odor threshold, traditional adsorption methods are insufficient to effectively address odor pollution. Furthermore, adsorbents like activated carbon are easily saturated, leading to high replacement costs and the risk of secondary release. Many current room-temperature catalytic methods, such as photocatalysis and DBD plasma catalysis, are more targeted and cannot achieve broad-spectrum removal of many odors. They also suffer from high energy consumption, and their odor removal efficiency needs improvement. In addition, while thermocatalytic oxidation has a strong broad-spectrum effect on VOCs, its application is limited by heating methods and ambient temperature requirements, hindering its widespread use in home environments. Furthermore, some technologies employ water washing and spraying to remove air pollutants. However, the washing solution is easily carried away by airflow, posing a risk of cross-contamination, and its removal efficiency is relatively low.
[0099] To address at least one of the aforementioned technical problems, the purification component 100 according to an embodiment of the present invention employs membrane absorption, combined with odor-absorbing liquid 7, which boasts high odor removal capacity, is easy and efficient to replace, and possesses multiple mechanisms of action such as absorption, capture, complexation, coating, and degradation, eliminating the risk of secondary release. Membrane absorption enables broad-spectrum absorption and removal of polar, non-polar, and weakly polar odors, removing inorganic hydrogen sulfide, ammonia, and other odors, as well as formaldehyde and VOCs. It consumes little energy, requiring only the continuous or intermittent circulation of the odor-absorbing liquid 7, resulting in significant removal efficiency. In membrane absorption, air flows through the breathable membrane tube 2, while the odor-absorbing liquid 7 flows through the outside. Gas and liquid can be absorbed through contact via the breathable membrane, preventing the odor-absorbing liquid 7 from being carried away by the airflow and eliminating the risk of cross-contamination. Furthermore, the array arrangement of the breathable membrane tube 2 greatly increases the contact area, significantly enhancing odor removal efficiency.
[0100] The purification component 100 according to a specific embodiment of the present invention will now be described.
[0101] Figures 1-3As shown, the purification component 100 may include: a housing 1, a breathable membrane tube 2, and a liquid supply device. The housing 1 includes a first wall 11 and a second wall 12 that are arranged opposite to each other and spaced apart. The first wall 11 is provided with a plurality of air inlets 111, and the second wall 12 is provided with a plurality of air outlets 121. A first chamber 101, a second chamber 102, and a third chamber 103 are formed between the first wall 11 and the second wall 12. All air inlets 111 and all air outlets 121 are arranged directly opposite the first chamber 101. The breathable membrane tube 2 is located in the first chamber 101 and extends along the direction from the first wall 11 to the second wall 12. The two ends of the breathable membrane tube 2 are respectively connected to the air inlets 111 and the air outlets 121.
[0102] like Figures 1-3 As shown, the second chamber 102 and the third chamber 103 are both located on the same side of the length of the first chamber 101, and the second chamber 102 is located above the third chamber 103. The first chamber 101 has an inlet 1011 communicating with the third chamber 103 and an outlet 1012 communicating with the second chamber 102. The outlet 1012 is located above the inlet 1011. The second chamber 102 has an injection port 1021 and a suction port 1022 communicating with the third chamber 103. The liquid supply device includes a micro liquid pump 31, a suction pipe 32, a supply pipe 33, and a control line 34. The control line 34 connects the micro liquid pump 31 to an external control board. The suction pipe 32 connects the micro liquid pump 31 to the suction port 1022. The supply pipe 33 connects the micro liquid pump 31 to the inlet 1011. The injection port 1021 is equipped with a switch cover 4.
[0103] After assembling the purification component 100, open the switch cover 4 and inject the odor-absorbing liquid 7 into the second chamber 102, then close the switch cover 4. Install the purification component 100 at the air inlet or outlet of an air handling device, such as an air conditioner or air purifier. Connect the control line 34 to the external control board to automatically adjust the pump speed of the micro liquid pump 31. The odor-absorbing liquid 7 circulates in the first chamber 101. The odor-absorbing liquid 7 in the first chamber 101 flows back to the second chamber 102 through the drain port 1012. Alternatively, the odor-absorbing liquid 7 in the second chamber 102 is drawn into the micro liquid pump 31 through the suction pipe 32 and flows into the first chamber 101 through the supply pipe 33. When the injected amount in the first chamber 101 exceeds a certain amount, the excess odor-absorbing liquid 7 flows back to the second chamber 102 through the drain port 1012. Odor pollutants in the air flow through the breathable membrane tube 2 and are absorbed, captured, complexed, coated, and degraded by the odor absorption liquid 7 in the first chamber 101, thus achieving efficient removal of odors from the air.
[0104] To further verify the performance of the purification component 100 in the above embodiment, the following experimental tests were conducted.
[0105] Experiment 1
[0106] Odor-absorbing liquid 7 is mainly composed of water, surfactants, acid-base buffers, metal ions, organic supramolecular molecules, nano-catalysts, and hydrogen peroxide. Specifically, it can consist of water, 0.2% polymerized amino acids, 1% citric acid-sodium citrate, and 0.1% Cu. 2+ It is composed of 0.5% hydroxypropyl cyclodextrin, 0.1% nano titanium dioxide, 5% hydrogen peroxide, etc.
[0107] The breathable membrane tube 2 is made of high-molecular polymer PTFE. The wall thickness of the breathable membrane tube 2 is 180μm, the outer diameter is 3mm, and the air permeability is 2.3L / min / cm. 2 (7kPa), water permeability resistance is 40kPa, and an array of approximately 5000 breathable membrane tubes 2 arranged in multiple rows and columns has a contact area of 1.4m² with the odor-absorbing liquid 7. 2 The axial length of the breathable membrane tube 2 is 30mm-50mm.
[0108] The flow rate of the miniature liquid pump 31 is 0.01 L / min - 1 L / min. The purification component 100 is installed at the air inlet of the air conditioner; the fan speed after the air conditioner is turned on is 350 m / s. 3 / h, at 30m 3 In the standard environmental chamber test, air flows through multiple breathable membrane tubes 2 from the air inlet 111 to the air outlet 121. Odor pollutants in the air are absorbed, captured, complexed, coated, and degraded by the odor absorption liquid 7 in the first chamber 101 through the breathable membrane tubes 2, which can achieve efficient removal of odors in the air. The experimental results show that the removal rate of common indoor odor pollutants such as formaldehyde, trimethylamine, ammonia, and toluene is greater than 90% in 0.5 hours and greater than 99% in 1 hour.
[0109] Experiment 2
[0110] Odor-absorbing liquid 7 is mainly composed of water, surfactants, acid-base buffers, metal ions, and organic supramolecular components. Specifically, it can consist of water, 0.4% polyalkyl glycoside (APG), 1% citric acid-sodium hydroxide, and 0.02% Ag. + It is composed of 0.5% hydroxypropyl cyclodextrin, 0.1% nano zinc oxide / activated carbon composite particles, 1% hydrogen peroxide, etc.
[0111] The breathable membrane tube 2 is made of high molecular weight polymer PVDF. The wall thickness of the breathable membrane tube 2 is 100μm, the outer diameter is 2mm, and the air permeability is 2.5L / min / cm. 2 (7kPa), water permeability resistance 36kPa, an array of approximately 6000 breathable membrane tubes arranged in multiple rows and columns, with a contact area of 1.13m² with the odor-absorbing liquid 7. 2 The axial length of the breathable membrane tube 2 is 30mm-50mm.
[0112] The flow rate of the miniature liquid pump 31 is 0.01L / min-1L / min. The purification component 100 is installed at the air inlet of the air conditioner; the fan speed after the air conditioner is turned on is 420m. 3 / h, at 30m 3 In the standard environmental chamber test, air flows through multiple breathable membrane tubes 2 from the air inlet 111 to the air outlet 121. Odor pollutants in the air are absorbed, captured, complexed, coated, and degraded by the odor absorption liquid 7 in the first chamber 101 through the breathable membrane tubes 2, which can achieve efficient removal of odors in the air. The experimental results show that the removal rate of common indoor odor pollutants such as formaldehyde, trimethylamine, ammonia, and toluene is greater than 90% in 0.5 hours and greater than 99% in 1 hour.
[0113] In addition, the applicant also conducted a comparative experiment.
[0114] Comparative Experiment 1
[0115] The experimental conditions for Comparative Experiment 1 and Experiment 2 were basically the same, the main differences being the composition of the odor-absorbing liquid 7 and the test wind speed. In Comparative Experiment 1, the odor-absorbing liquid 7 was mainly composed of water and 5% hydrogen peroxide, and the wind speed after the air conditioner was turned on was 350 m³ / h. The results of Comparative Experiment 1 showed that the removal rates of common indoor odor pollutants such as formaldehyde, trimethylamine, ammonia, and toluene within 1 hour were 87%, 82%, 85%, and 15%, respectively. Therefore, the selection of the components of the odor-absorbing liquid 7 is crucial.
[0116] Comparative Experiment 2
[0117] The deodorization module uses activated carbon adsorption, filled with activated carbon granules in a honeycomb panel. The panel measures 900*450*30mm, with 10mm honeycomb pores and an activated carbon filling of 65%. The air conditioner fan speed is 350 m / s. 3 / h, place the adsorption and deodorization module at the air inlet of the air conditioner, at 30m 3 In a standard environmental chamber test, the removal rates of common indoor odor pollutants such as formaldehyde, trimethylamine, ammonia, and toluene within 1 hour were 85%, 73%, 75%, and 98%, respectively. This demonstrates that the odor removal effect of the activated carbon adsorption module is inferior to that of the purification component 100 in this application, and it also takes longer.
[0118] In summary, the purification component 100 according to the embodiments of the present invention can be widely used in air handling equipment such as air conditioners and air purifiers. It is washable, the odor absorption liquid 7 is easy to replace, has low energy consumption, no cross-contamination, and the removal rate of common indoor odor pollutants such as formaldehyde, trimethylamine, ammonia, and toluene is greater than 99%.
