Description

Technical Field

[0001] The present invention relates to the field of air storage, and in particular to a forest essence gas purification and storage device. Background Art

[0002] With the rapid development of industrialization and urbanization, air pollution has become a global problem, seriously affecting people's health and quality of life. Although air purifiers can improve indoor air quality to a certain extent, their effects are limited by the pollution level of the external air. In contrast, forest areas usually have better air quality due to their rich vegetation and low pollution levels.

[0003] Research shows that forest plants can release volatile organic compounds called phytoncides, which have biological activities such as antibacterial, anti-inflammatory, and anti-allergic effects. The forest essence rich in oxygen and phytoncides in the forest can promote smooth breathing and improve mental state. Therefore, extracting and utilizing forest essence to provide fresh air similar to that of the forest for urban residents has become one of the current research hotspots.

[0004] However, affected by industrial pollution, even the air in forests near cities may contain dust and other pollutants. In addition, the microorganisms and specific odors emitted by plants in the forest environment may also affect the quality of forest essence. Therefore, the air directly extracted from the forest is not suitable for direct human breathing and requires a series of purification treatments. However, some air purification solutions in the prior art are not targeted at forest essence, so they cannot meet the multiple purification requirements of forest essence. Moreover, conventional gas storage generally uses hard metal gas storage tanks, which, although having certain pressure resistance, have problems such as large weight, poor portability, insufficient storage flexibility, and high batch transportation costs. Therefore, there is an urgent need for a device that can meet the multiple purification requirements of forest essence gas and is convenient for storing the purified forest essence gas.

Detailed implementation manners

[0038] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", "vertical", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention.

[0040] In the present invention, unless otherwise clearly defined and limited, terms such as "installation", "connection", "linkage", "fixation", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] In the description of the present invention, "the first feature", "the second feature" may include one or more of such features. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0042] As Figures 1 - 9 shown, a forest essence gas purification and storage device includes: a base 1, a multi-stage purification module and a storage module. Universal wheels 8 are provided at the bottom of the base 1, thereby facilitating the movement of the device and improving the flexibility of the device.

[0043] As Figures 1 - 3 shown, the multi-stage purification module includes a purification tank 2, a filtering unit, an adsorption unit, a sterilization unit and a recovery unit. The purification tank 2 is provided on the base 1. An air inlet pipe 3 is provided on one side of the purification tank 2, and an air outlet pipe 4 is provided on the other side. In this solution, taking Figure 1 a perspective as an example, the left side of the purification tank 2 is the air inlet pipe 3, and the right side is the air outlet pipe 4. The gas can enter the purification tank 2 through the air inlet pipe 3 and then be discharged from the purification tank 2 through the air outlet pipe 4.

[0044] The filtering unit includes a vertically placed filter mesh plate 5, and the filter mesh plate 5 is detachably provided in the purification tank 2; the adsorption unit includes a vertically placed adsorption layer 6, and the adsorption layer 6 is filled with an adsorbent 22. The adsorption layer 6 is detachably provided in the purification tank 2 and is located on the downstream side of the filter mesh plate 5.

[0045] In this solution, as Figure 2 shown, the adsorption layer 6 is located on the right side of the filter mesh. The gas entering the purification tank 2 will first pass through the left filter mesh plate 5 for filtration and then pass through the right adsorption layer 6 for adsorption and purification. The sterilization unit is a plasma sterilization module 28, and the plasma sterilization module 28 is provided on the air outlet pipe 4.

[0046] As Figure 4 , Figure 5 and Figure 6As shown, the recovery unit includes a vibration mechanism, a regeneration mechanism, and an exhaust mechanism. The vibration mechanism is used to vibrate the two vertical edges on one side surface of the filter mesh plate 5 and the other two vertical edges on the opposite side surface respectively.

[0047] That is to say, the vibration mechanism can vibrate the two vertical edges on the left side surface of the filter mesh plate 5 and the two vertical edges on the right side surface, and the two vertical edges on the left and right sides are different. For example, Figure 5 in [the figure], the right edge and the lower edge on the left side surface of the filter mesh plate 5 vibrate. Figure 6 in [the figure], the upper edge and the left edge on the right side surface of the filter mesh plate 5 vibrate. In this way, different edges on different sides of the filter mesh plate 5 can be vibrated, which can effectively improve the vibration efficiency, is conducive to quickly and fully loosening and shedding the particulate impurities on the filter mesh plate 5, quickly restoring the filtering performance of the filter mesh plate 5, thereby extending the service life of the filter mesh plate 5, prolonging the replacement cycle, and reducing the replacement and use cost of the filter mesh plate 5.

[0048] As Figure 7 shown, the regeneration structure is used to heat the adsorbent 22 to restore the adsorbability of the adsorbent 22. By heating the adsorbent 22, the pollutants adsorbed on the adsorbent 22 can be volatilized or decomposed, thereby restoring the adsorption capacity of the adsorbent 22. In this way, it is not necessary to frequently replace the adsorption layer 6, and the replacement and use cost of the adsorption layer 6 can be reduced.

[0049] The exhaust unit is used to exhaust the waste gas in the purification box 2 when the vibration mechanism and the regeneration mechanism are working.

[0050] As Figures 1 - 3 shown, the storage module includes a flexible air storage bag 7. The air storage bag 7 is detachably connected to the air outlet pipe 4. Different from the conventional solution that uses a rigid metal gas storage tank, this solution uses a flexible air storage bag 7 to store gas, which is not only lighter in overall weight, effectively improving the portability, but also can automatically adjust the volume according to the gas pressure, making the storage more flexible and convenient. And in order to ensure that the air storage bag 7 can store gas at a certain pressure, as Figure 8 and Figure 9 shown, a reinforcing member is also provided inside the air storage bag 7. The reinforcing member can make the air storage bag 7 have higher structural strength and pressure resistance, improving the use reliability and safety of the air storage bag 7.

[0051] When this device is in use, the air inlet pipe 3 is connected to a gas supply device such as an air pump. After the gas enters the purification box 2, it first passes through the filter mesh plate 5 for filtering particulate impurities, then passes through the adsorption layer 6 for adsorption and purification, and finally passes through the plasma sterilization module for sterilization and disinfection. The purified gas will flow to the air storage bag 7 for storage.

[0052] After using for a period of time, the recovery unit can be activated to restore the filtering performance of the filter mesh plate 5 and the adsorption performance of the adsorption layer 6. Among them, the vibration mechanism can vibrate different edges on different sides of the filter mesh plate 5 to quickly and fully loosen and shed the particulate impurities on the filter mesh plate 5, quickly restoring the filtering performance of the filter mesh plate 5. The regeneration structure can heat the adsorbent 22 in the adsorption layer 6 to volatilize or decompose the pollutants adsorbed on the purification material, thereby restoring the adsorption capacity of the adsorbent 22. The exhaust unit is used to discharge the waste gas in the purification box 2 when the vibration mechanism and the regeneration mechanism are working. Thus, the restored filter mesh plate 5 and adsorption layer 6 can continue to work for a period of time. When their performance still no longer meets the usage requirements after being restored, the purification box 2 can be opened to disassemble and replace the filter mesh plate 5 and the adsorption layer 6.

[0053] The other structures of the present device will be introduced in detail below with reference to the accompanying drawings.

[0054] As Figure 8 and Figure 9 shown, a wire mesh 9 that wraps the inner space of the air storage bag 7 is provided in the middle interlayer of the air storage bag 7. The provided wire mesh 9 can play a certain role in restricting the deformation of the air storage bag 7. When the internal pressure of the air storage bag 7 increases, the wire mesh 9 can restrain the expansion degree of the airbag, making it maintain a relatively stable shape, thereby improving the stability and reliability of the air storage bag 7 under high-pressure conditions.

[0055] In addition, a cable 10 is provided on the inner wall surface of the air storage bag 7. The cable 10 extends along the radial direction of the air storage bag 7 and is connected to the air storage bag 7 at both ends. There are multiple cables 10, and the multiple cables 10 are divided into cable 10 layers arranged at intervals along the axial direction of the air storage bag 7. Each cable 10 layer includes several cables 10 arranged at intervals along the circumferential direction of the air storage bag 7. The cable 10 can hold the air storage bag 7 when the air storage bag 7 expands, preventing the air storage bag 7 from being damaged due to excessive expansion. After cooperating with the wire mesh 9, the high-pressure resistance and usage reliability of the air storage bag 7 can be effectively improved.

[0056] As Figure 2 shown, an air delivery pipe 11 is provided on the air storage bag 7. The air delivery pipe 11 is detachably connected to the air outlet pipe 4. A first on-off valve 12 is provided on the air delivery pipe 11 to control the opening and closing of the air delivery pipe 11. Flange rings can be provided on both the air delivery pipe 11 and the air outlet pipe 4, and the flange rings of the two can be connected by bolts and nuts to achieve the detachable connection of the two pipelines. This is a conventional connection method and will not be elaborated here.

[0057] As Figure 1 、 Figure 2 and Figure 4As shown in the figure, a lid 13 is provided on the upper side of the purification box 2. The lid 13 is rotatably connected to the purification box 2 to open or close the purification box 2. Vertical first card slots 14 and second card slots 15 are provided on the inner wall of the purification box 2. The filter mesh plate 5 is detachably inserted into the first card slot 14 from top to bottom, and the adsorption layer 6 is detachably inserted into the second card slot 15 from top to bottom. Thus, the detachable connection between the filter mesh plate 5 and the adsorption layer 6 and the purification box 2 can be realized.

[0058] As Figure 2 , Figure 4 , Figure 5 and Figure 6 shown, the vibration mechanism includes a driving mechanism and a set of rotating shafts 16 respectively provided on both side surfaces of the filter mesh plate 5. Each set of rotating shafts 16 includes two vertically distributed rotating shafts 16. The two rotating shafts 16 are arranged parallel to two vertical edges on the corresponding side surface of the filter mesh plate 5. The rotating shafts 16 are rotatably connected to the inner wall of the purification box 2. A number of elastic cams 17 are arranged at intervals along the length direction of the rotating shafts 16. When the elastic cams 17 rotate with the rotating shafts 16, they can touch the edges of the filter mesh plate 5. The driving mechanism is connected to the four rotating shafts 16 to drive the four rotating shafts 16 to rotate.

[0059] That is to say, the vibration mechanism realizes the vibration of the filter mesh plate 5 by the periodic collision of the elastic cams 17 with the edges of the filter mesh plate 5. The elastic cams 17 can be, for example, rubber cams, so as to avoid excessive impact of the elastic cams 17 on the filter mesh plate 5, resulting in damage to the filter mesh plate 5. The used filter mesh plate 5 has a structure with a hard frame around the periphery and a filter mesh in the middle.

[0060] The driving mechanism includes a motor 18, a first transmission component and a second transmission component. The two vertically distributed rotating shafts 16 in each set of rotating shafts 16 are connected by the first transmission component, and the horizontally arranged rotating shafts 16 in the two sets of rotating shafts 16 are connected to the motor 18 through the second transmission component.

[0061] Among them, the first transmission component is a bevel gear transmission component 19, that is, a bevel gear is respectively provided on the two vertically distributed rotating shafts 16, and the two bevel gears are meshed to realize the transmission of the two vertical rotating shafts 16. The second transmission component is a sprocket transmission component 20, that is, the horizontally arranged rotating shafts 16 in the two sets of rotating shafts 16 respectively extend out of the purification box 2 and then are provided with sprockets. The sprockets are connected by a chain. The motor 18 is connected to one of the sprockets to drive the horizontally arranged rotating shafts 16 in the two sets of rotating shafts 16 to rotate. Then, through the transmission of the two bevel gear transmission components 19, the rotation of the four rotating shafts 16 can be finally realized. This transmission form is simple and easy to realize. During the later regular maintenance, the purification box 2 can be opened, and the particulate impurities that may fall on the cams or bevel gears can be removed by using a brush or an air gun for simple maintenance.

[0062] AsFigure 7 As shown in the figure, the adsorption layer 6 includes an insulating outer mesh cover 21 and an adsorbent 22 filled inside the outer mesh cover 21. The regeneration mechanism includes a power supply, a switch, a heating wire 23, a first electrode plate 24, and a second electrode plate. The heating wire 23 is inserted through the adsorbent 22. Two first electrode plates 24 are provided at the bottom of the outer mesh cover 21, and the first electrode plates 24 are connected to the heating wire 23. Two second electrode plates are provided on the inner wall of the purification box 2, and the second electrode plates are connected to the power supply and the switch.

[0063] That is to say, when the adsorption layer 6 is installed in the purification box 2, the two first electrode plates 24 are connected to the two second electrode plates in one-to-one correspondence, and a circuit is formed at this time. When the switch is turned on, the heating wire 23 is powered on and heated, and the adsorbent 22 can be heated and regenerated to recover. The provided power supply supplies power to each electrical component of this device.

[0064] The adsorbent 22 used can be, for example, activated carbon. Activated carbon is a commonly used purification material with a high specific surface area and a rich pore structure, and can effectively adsorb organic pollutants. It can also be a molecular sieve. The molecular sieve has uniform pore sizes and high adsorption selectivity, and is suitable for adsorbing molecules of specific sizes. During the heating process, the adsorbed substances in the activated carbon or molecular sieve will volatilize or decompose at high temperatures, thereby restoring their adsorption capacity.

[0065] As Figures 1 - 4 shown in the figure, the exhaust mechanism includes a waste discharge pipe 25 and a fan 27. The filter mesh plate 5 and the adsorption layer 6 divide the internal space of the purification box 2 into three chambers. The bottom of each chamber is respectively recessed downward to form a funnel 26. The bottoms of the three funnels 26 are connected to the fan 27 through the waste discharge pipe 25. A second switching valve is provided on the waste discharge pipe 25, and the second switching valve is used to control the opening and closing of the waste discharge pipe 25. When normally purifying and storing gas, the second switching valve is in the closed state. When it is necessary to recover the filter mesh and the adsorption layer 6, the first switching valve 12 is closed, the second switching valve is opened, and the fan 27 can discharge the waste gas generated during the recovery.

[0066] As Figure 4 shown in the figure, the sterilization unit is a plasma sterilization module 28. The plasma sterilization module 28 is provided on the air outlet pipe 4, and thus the gas flowing through the air outlet pipe can be finally sterilized and disinfected to remove harmful microorganisms in the gas. Plasma sterilization is a technology that uses gas discharge to generate plasma (ionized gas) for sterilization. The plasma contains various active substances, such as ions, electrons, free radicals, and ultraviolet rays (UV). These active substances can react with the cell walls and cell membranes of bacteria, viruses, and other microorganisms, resulting in oxidative stress of cell components, thereby destroying the cell structure. This plasma sterilization module is currently mostly applied to various air purifiers and belongs to mature existing technologies. Those skilled in the art can select according to actual needs and will not be elaborated here.

[0067] When this device is used to store forest essence gas, the extracted forest essence gas will undergo multiple stages of treatment including filtration purification, adsorption purification, and sterilization purification in sequence, and then be stored under high pressure by the storage airbag 7. This can effectively remove particulate impurities, gas odors, and pathogenic microorganisms that may exist in the forest essence gas, making the forest essence gas purer. In this way, the forest essence gas is not prone to deterioration and can be stored stably for a long time.

[0068] In addition, substances such as desiccants and activated carbon can be further added into the storage airbag 7, which helps to extend the storage time of the forest essence gas in the storage airbag and makes it even less prone to deterioration.

[0069] In summary, this device has the following characteristics:

[0070] 1. This device integrates the functions of multi-stage air purification and storage. It can perform multi-stage treatment of filtration purification, adsorption purification, and sterilization purification on air, especially forest essence gas, and then store it. This can effectively ensure the purity of the stored gas, enabling the gas to be stored stably for a long time.

[0071] 2. The filter mesh plate 5 and the adsorption layer 6 are both detachable, facilitating later replacement. The provided restoration unit can restore the performance of the filter mesh plate 5 and the adsorption layer 6. Among them, the vibration mechanism of the restoration unit can make different edges on different sides of the filter mesh plate 5 vibrate, thereby effectively improving the vibration efficiency, which is beneficial to quickly and fully loosen and shed the particulate impurities on the filter mesh plate 5, and rapidly restore the filtering performance of the filter mesh plate 5. The regeneration mechanism of the restoration unit can heat the adsorbent 22 in the adsorption layer 6 to volatilize or decompose the pollutants adsorbed on the adsorbent 22, thereby restoring the adsorption capacity of the adsorbent 22. Thus, the replacement frequency of the filter mesh plate 5 and the adsorption layer 6 can be significantly reduced, the replacement cycle can be extended, and the usage cost can be reduced.

[0072] 3. The gas storage uses a flexible storage airbag 7, which is not only lighter in overall weight and convenient for batch transportation, but also can automatically adjust its volume according to the gas pressure, making the storage more flexible and convenient.

[0073] 4. The flexible storage airbag 7 is provided with a strengthening member, which can make the storage airbag 7 have higher structural strength and pressure resistance, improving the use reliability and safety of the storage airbag 7.

[0074] Although some embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that: without departing from the principles and purposes of the present invention, various changes, modifications, substitutions, and variations to these embodiments are all within the protection scope of the claims of the present invention.
