[0002] In the related art, people are paying more and more attention to the air quality in their living environment, and as a result, the use of air purification devices is increasing. To remove HCHO (formaldehyde) and VOC (volatile organic compounds) from the air, the first filtration method in the existing art uses adsorption materials such as activated carbon and molecular sieves. However, the adsorption capacity of adsorption materials is limited, and they are prone to adsorption saturation, resulting in poor adsorption function and short-term filtration performance.

[0003] The second filtering method in the existing technology is to use high-temperature catalytic technology, which adsorbs VOCs by heating the catalyst to above 200°C. However, the high temperature of around 200°C limits its use in indoor purification. During long-term use, the catalyst will also adsorb aerosols and gases that cannot be decomposed, resulting in a gradual deterioration in purification performance.

DETAILED DESCRIPTION

[0030] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0033] In the present invention, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood broadly. For example, they may refer to fixed or detachable connections, or integration; mechanical or electrical connections, or communication; direct or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0034] The present invention will be described below with reference to specific embodiments in conjunction with the accompanying drawings. Figures 1-4 Each of them is a side view of the plasma regeneration assembly 100 .

[0035] First combine Figures 1-4 The plasma regeneration assembly 100 according to an embodiment of the present invention is described. It should be noted that the plasma regeneration assembly 100 according to the embodiment of the present invention can not only filter gases such as air, but also filter some non-conductive liquids to avoid safety risks caused by liquid electrification.

[0036] like Figures 1-4 As shown, the plasma regeneration assembly 100 of an embodiment of the present invention may include an adsorption filter module 1, a discharge element 2, and a ground electrode 3, with the adsorption filter module 1 being located between the discharge element 2 and the ground electrode 3. The power supply can transmit power to the discharge element 2, and the ground electrode 3 does not necessarily need to be in contact with the ground, as long as the power supply does not directly charge the ground electrode 3. It is understood that when the adsorption filter module 1 performs filtration for a long time, residual substances such as VOCs (volatile organic compounds) (e.g., filter residue) will adhere to the adsorption filter module 1. The residual substances attached to the adsorption filter module 1 will reduce the filtration capacity of the adsorption filter module 1.

[0037] When the power source transmits power to the discharge element 2, a voltage difference is generated between the discharge element 2 and the ground electrode 3, so that the discharge element 2 can discharge to the ground electrode 3. The discharge element 2 can have a sufficiently high voltage (for example, a voltage of 1000V or higher). Under the high voltage, the air between the discharge element 2 and the ground electrode 3 becomes a conductor, so that the discharge element 2 discharges to the ground electrode 3 through the air.

[0038] Therefore, when the discharge element 2 discharges toward the ground electrode 3, the air and other materials in the space between the discharge element 2 and the ground electrode 3 are charged and transformed into a plasma state, thereby forming a plasma. At this point, not only can the charged discharge element 2 and the ground electrode 3, under the action of electromagnetic force, absorb at least some of the residual material attached to the filter module 1, but the plasma can also absorb at least some of the residual material attached to the filter module 1. Simultaneously, the flowing air can carry away the residual material absorbed by the plasma. The plasma can also decompose the absorbed formaldehyde into water and carbon dioxide, which are discharged into the air, thereby protecting the environment.

[0039] According to the plasma regeneration assembly 100 of an embodiment of the present invention, the discharge component 2 can generate plasma substances during the discharge process to decompose and adsorb at least part of the residual substances in the adsorption filter module 1, thereby avoiding excessive residual substances remaining on the adsorption filter module 1 and reducing the filtering performance of the adsorption filter module 1, and ensuring that the adsorption filter module 1 has long-term effective filtering performance.

[0040] In some specific embodiments, the discharge element 2 can discharge while the fluid is being filtered by the adsorption filter module 1, and timely adsorb residual substances attached to the adsorption filter module 1, so as to ensure that the adsorption filter module 1 has good filtering ability at all times when filtering the fluid.

[0041] In other embodiments, the discharge element 2 may also discharge at regular intervals or when the fluid stops passing through the adsorption and filtration module 1 to regularly adsorb residual substances attached to the adsorption and filtration module 1 and save electrical energy.

[0042] In some specific embodiments, the plasma regeneration assembly 100 is provided with multiple layers of insulation protection to prevent personnel from directly touching high-voltage components such as the discharge component 2, thereby ensuring safe use.

[0043] In some specific embodiments, the adsorption filtration module 1 can be a filter mesh, and the discharge component 2 and the ground electrode component 3 can both include electrode plates. Each of the discharge component 2 and the ground electrode component 3 can include only one electrode plate, or can be formed by a plurality of spaced-apart electrode plates electrically connected. A fluid channel can be formed between the two electrode plates to allow the fluid to pass through the discharge component 2, thereby facilitating the fluid to pass smoothly through the plasma regeneration assembly 100.

[0044] Specifically, if Figures 1-4As shown, the electrode plates of the discharge element 2 can be parallel to the electrode plates of the ground electrode 3, so that the electrode plates of the discharge element 2 can directly face the electrode plates of the ground electrode 3, thereby improving the discharge effect. At the same time, the adsorption filter module 1 can be opposite the electrode plates of the discharge element 2 to increase the contact area between the plasma objects generated by the discharge element 2 and the adsorption filter module 1, ensuring the adsorption effect of the plasma objects on the residual substances on the adsorption filter module 1, and simultaneously improving the electromagnetic adsorption effect of the discharge element 2 and the ground electrode 3 on the residual substances on the adsorption filter module 1.

[0045] In some specific embodiments, the adsorption filter element 1 can be a mixed extrusion molding of one or more of activated carbon, molecular sieve, and MOF (metal-organic framework). The adsorption filter element 1 contains a catalyst, and the catalyst can be one or more of precious metals such as Pt and Ba, metal oxides such as Mn2Ox, CuO, and CeO. Activated carbon, molecular sieves, and catalysts all have adsorption effects. In other embodiments, the adsorption filter element 1 can also be loaded on a substrate, and the substrate can be nickel foam, honeycomb aluminum, bromine, etc. The catalyst can be a precious metal such as platinum, palladium, silver, etc., or a metal oxide such as manganese oxide, cerium dioxide, copper oxide, etc. In some other embodiments, the catalyst can also be loaded on activated carbon and molecular sieves, and then molded or loaded.

[0046] In some optional embodiments of the present invention, as Figure 3-Figure 4 As shown, the plasma regeneration assembly 100 includes a first adsorption filter module 11 and a second adsorption filter module 12 arranged opposite each other. The discharge element 2 is located between two adjacent adsorption filter modules 1. The ground electrode 3 includes a first ground electrode 31 and a second ground electrode 32. The first ground electrode 31 is located on the side of the first adsorption filter module 11 facing away from the discharge element 2, and the second ground electrode 32 is located on the side of the second adsorption filter module 12 facing away from the discharge element 2. As a result, the discharge element 2 can simultaneously discharge the first ground electrode 31 and the second ground electrode 32, thereby generating plasma between the discharge element 2 and the first ground electrode 31 and between the discharge element 2 and the second ground electrode 32. This can simultaneously adsorb residual substances in the first adsorption filter module 11 and the second adsorption filter module 12, thereby improving cleaning efficiency.

[0047] More specifically, the plasma regeneration components 100 may be multiple groups arranged side by side and facing each other, and the fluid passes through the multiple groups of plasma regeneration components 100 in sequence to improve the cleaning effect of the adsorption filter.

[0048] In some specific embodiments, the discharge element 2 is a DC discharge element, i.e., a DC power source can pass DC current to the discharge element 2. The discharge element 2 is a conductor or has a conductor layer. The conductor layer can be metal or graphite, and can be cylindrical, threaded, elongated, or in a special shape. Therefore, the structure of the discharge element 2 is simple.

[0049] More specifically, Figure 2 As shown, the discharge member 2 is arranged in close contact with the adsorption filter module 1. Thus, the discharge member 2 is directly electrically connected to the adsorption filter module 1. The discharge member 2 and the adsorption filter module 1 are integrated as the discharge member 2, which not only improves the electromagnetic adsorption force of the discharge member 2 on the adsorption filter module 1, but also saves the layout space of the plasma regeneration assembly 100.

[0050] In other embodiments, the ground electrode 3 is disposed in close contact with the adsorption and filtration module 1. Thus, the ground electrode 3 is directly electrically connected to the adsorption and filtration module 1, and the discharge element 2 and the adsorption and filtration module 1 serve as the ground electrode 3 as a whole. This not only improves the electromagnetic adsorption force of the ground electrode 3 on the adsorption and filtration module 1, but also saves space for the arrangement of the plasma regeneration assembly 100.

[0051] Optionally, for example, in an embodiment in which the discharge member 2 is fitted with the adsorption and filtration module 1 or the ground electrode member 3 is fitted with the adsorption and filtration module 1 (for illustrative purposes only), both the discharge member 2 and the ground electrode member 3 are provided with a fluid flow port adapted to be opposite to the adsorption and filtration module 1, so as to facilitate smooth passage of the fluid through the plasma regeneration assembly 100 and achieve filtration.

[0052] In other embodiments, the discharge element 2 is an AC discharge element or a pulse discharge element. That is, an AC power source can pass AC or pulse current through the discharge element 2. The discharge element 2 comprises a conductive layer and an insulating layer. The conductive layer can be made of metal or graphite and can be cylindrical, threaded, elongated, or a special-shaped structure. The insulating layer can be made of ceramic, quartz, polytetrafluoroethylene, or the like, and is suitable for wrapping around the conductive layer. As a result, the discharge element 2 generates more plasma during discharge than when using DC power, and has a stronger ability to adsorb residual substances from the adsorption and filtration module 1.

[0053] In other embodiments, Figure 1 、 Figure 3 and Figure 4 As shown, the discharge member 2 and the ground electrode member 3 are both spaced apart from the adsorption filter module 1. Thus, the side of the adsorption filter module 1 facing the discharge member 2 and the side of the adsorption filter module 1 facing the ground electrode member 3 both have space to generate more plasma, thereby improving the adsorption effect of residual substances remaining on the adsorption filter module 1. At the same time, space is provided for the flow of plasma, facilitating the plasma to carry the residual substances away from the adsorption filter module 1.

[0054] Specifically, if Figure 3 and Figure 4As shown, the discharge member 2 has a rotating shaft 21. One or both ends of the discharge member 2 may be provided with a driving member 22 connected to the rotating shaft 21. More specifically, the driving member 22 may be a motor, and the output shaft of the motor may be connected to the rotating shaft 21 to drive the discharge member 2 to rotate. The discharge member 2 has an adsorption position parallel to the adsorption and filtration module 1 and a storage position perpendicular to the adsorption and filtration module 1. The discharge member 2 can be rotated by the rotating shaft 21 to switch between the adsorption position and the storage position.

[0055] When the discharge member 2 is in the adsorption position, the discharge member 2 can be parallel to the ground electrode 3 to improve discharge efficiency and increase the amount of plasma objects generated. When the discharge member 2 is in the storage position, the fluid passing through the plasma regeneration assembly 100 has a larger passage space.

[0056] Similarly, the ground electrode 3 may also have a rotational axis similar to the rotational axis 21 to enable rotation, thereby switching between the adsorption position and the storage position. Thus, when the ground electrode 3 is in the adsorption position, it can be aligned parallel to the discharge element 2, thereby improving discharge efficiency and increasing the amount of plasma generated. When the ground electrode 3 is in the storage position, the fluid passing through the plasma regeneration assembly 100 has more space to pass through.
