[0027] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. Now, in conjunction with the accompanying drawings, the preferred embodiments of the present invention will be described in detail.

[0028] Reference Figures 1 to 5 The accompanying drawings illustrate an embodiment of the discharge device and purification equipment of the present invention. The discharge device comprises a discharge member 1 and a catalyst assembly 2. The discharge member 1 is provided with a plurality of through-holes 11 extending through both sides thereof. The catalyst assembly 2 is fixed to one side of the discharge member 1 and electrically connected thereto. The catalyst assembly 2 comprises a plurality of catalysts 21, which are arranged corresponding to the through-holes 11 and are used to absorb ozone. Discharge occurs between the inner walls of the through-holes 11 and the surfaces of the catalysts 21 to ionize the gas.

[0029] Specifically, plasma purification technology directly decomposes pollutants through the generation of highly active particles through ionization. It combines chemical oxidation and physical adsorption capabilities, making it suitable for air purification in multiple scenarios. Its core advantage lies in its ability to efficiently degrade complex pollutants without the need for consumables, leading to its application in various fields. However, the use of plasma purification to decompose pollutants produces a variety of byproducts, such as ozone. Exceeding the standard for ozone can easily cause harm to the human body and pose a threat to the environment.

[0030] Therefore, the present invention provides a discharge device and purification equipment, wherein the discharge device is used to generate plasma to purify the air, and the release of by-products is reduced by the discharge device, especially the control of ozone concentration, providing reliable technical support for the widespread application of plasma purification technology, so that ozone can be reduced or eliminated when decomposing and treating polluted gases.

[0031] The discharge device includes a discharge member 1 and a catalytic component 2. The discharge member 1 is used for high-voltage discharge to ionize the air. The discharge member 1 is provided with a plurality of through holes 11, which pass through both sides of the discharge member 1. The through holes 11 are used to pass air into the catalytic component 2 to ionize the air and generate plasma, which is then used to decompose pollutants and purify the air. The plurality of through holes 11 are evenly and spaced apart on the discharge member 1.

[0032] The catalytic component 2 is fixed on one side of the discharge member 1. In this embodiment, the catalytic component 2 is fixed on the bottom end of the discharge member 1. One end of the catalytic component 2 is electrically connected to one end of the discharge member 1, so that an electric field can be formed between the catalytic component 2 and the discharge member 1. The electric field is used to ionize the air to generate plasma, and the plasma is then processed to decompose pollutants to purify the air, thereby playing a purification and cleaning role.

[0033] The catalytic assembly 2 includes a catalyst 21, and a plurality of catalysts 21 are provided, and the plurality of catalysts 21 are respectively arranged in a one-to-one correspondence with the plurality of through holes 11, that is, the catalyst 21 is arranged below the through hole 11, and the upper surface of the catalyst 21 needs to be tightly fixed to the bottom end of the through hole 11 to ensure the catalytic and adsorption decomposition of ozone by the catalyst 21; the catalyst 21 is used to absorb in situ the ozone generated after the discharge device decomposes the pollutants, that is, the catalyst 21 absorbs the ozone for the first time to reduce the ozone concentration generated by the discharge device when treating the polluted gas.

[0034] Among them, the discharge element 1 and the catalytic component 2 constitute a discharge area, which is used to discharge to ionize the air to generate plasma and decompose pollutants to achieve air purification. The discharge occurs at the inner wall of the through hole 11 and the surface of the catalyst 21, so that the air is ionized on the inner wall of the through hole 11 and the surface of the catalyst 21 to generate plasma, thereby improving the ionization efficiency; the area where the catalyst 21 is located is a processing area, which is used to absorb or decompose the ozone generated when ionizing the air and decomposing pollutants, thereby reducing the ozone concentration generated by the discharge device during operation, effectively controlling the production of ozone, avoiding ozone exceeding the standard, improving human health, and avoiding threats to the environment.

[0035] More specifically, in this embodiment, ozone can be controlled and eliminated by the coverage of the through hole 11 by the catalyst 21. Generally, a coverage greater than 50% can control the ozone in a 45L volume cavity to below 50ppb, or even eliminate ozone.

[0036] The present application sets the discharge element 1 and the catalytic component 2, and the discharge element 1 and the catalytic component 2 are electrically connected so that the discharge element 1 and the catalytic component 2 form a discharge zone, discharge at the inner wall of the through hole 11 and the surface of the catalyst 21, so as to ionize and generate plasma and decompose the polluted gas, thereby improving the treatment efficiency of the plasma, ensuring the treatment of the polluted gas, and absorbing or decomposing the generated ozone through the catalyst 21, which can significantly reduce the ozone concentration, avoid ozone exceeding the standard, and improve the purification effect and equipment performance.

[0037] In one embodiment, referring to Figures 1 to 4 As shown, the catalytic assembly 2 further includes a fixed net 22 , which is fixed on one side of the discharge member 1 and electrically connected to the discharge member 1 , and the catalyst 21 is filled in the position of the fixed net 22 corresponding to the through hole 11 .

[0038] Specifically, the catalytic component 2 also includes a fixed mesh 22, which has the function of conducting electricity and fixing the catalyst 21. The fixed mesh 22 is fixed on one side of the discharge member 1. The shape and structure of the fixed mesh 22 are consistent with the shape and structure of the discharge member 1, so that the fixed mesh 22 is completely covered on one side of the discharge member 1. One end of the fixed mesh 22 is electrically connected to one end of the discharge member 1, so that when the power is turned on, the fixed mesh 22 and the discharge member 1 can be conductive to form an electric field between the fixed mesh 22 and the discharge member 1, thereby ionizing the air to generate plasma, so that the plasma can decompose and treat the pollutants and improve the purification effect.

[0039] Since the fixed net 22 has dense pores, the catalyst 21 can be fixed on the fixed net 22. In this embodiment, the catalyst 21 is loaded into the position of the fixed net 22 corresponding to the through hole 11 by filling, thereby improving the fixation of the catalyst 21. At the same time, the method of loading the catalyst 21 into the fixed net 22 is simple, easy to operate, and improves operating efficiency; and the catalyst 21 is in direct contact with the fixed net 22, thereby improving the catalytic efficiency of the catalyst 21, and also enabling the catalyst 21 to absorb or decompose ozone as much as possible, significantly reducing the ozone concentration.

[0040] More specifically, the fixed mesh 22 is electrically connected to the ground, and the discharge between the discharge member 1 and the surface of the catalyst 21 can be achieved by adjusting the surface resistance of the fixed mesh 22 .

[0041] More specifically, the two terminals of the power supply are respectively connected to the discharge element 1 and the fixed net 22, and the driving power supply is an AC high-frequency high-voltage power supply, so that the discharge element 1 and the fixed net 22 form a discharge area, and the discharge position is located on the inner wall of the through hole 11 and the surface of the catalyst 21, thereby realizing the treatment of polluted gas.

[0042] In a specific embodiment, the fixed mesh 22 is made of carbon nanotubes or organic silicon materials (not shown in the figure) with a surface resistance of 107-108Ω. Specifically, the carbon nanotube (CNT) is a carbon nanotube composed of carbon atoms in the form of sp 2 A one-dimensional nanoscale tubular structure material formed by hybridization, whose tube wall is composed of a single or multiple layers of curled graphene sheets. Single-layer graphene curled together is called single-walled carbon nanotubes (SWCNTs), while multi-layer graphene curled together is called multi-walled carbon nanotubes (MWCNTs). These carbon nanotubes typically have diameters ranging from a few nanometers to tens of nanometers and can reach lengths of microns or even millimeters. These carbon nanotubes have extremely high mechanical strength (tensile strength is over 100 times that of steel), excellent electrical and thermal conductivity, and a large specific surface area. They can be used as reinforcements in composite materials, as conductive / thermal fillers, and as materials for electronic devices.

[0043] The organosilicon material is a semi-inorganic and semi-organic polymer material with a silicon-oxygen bond (-Si-O-Si-) as the main molecular chain and organic groups (such as methyl, phenyl, vinyl, etc.) connected to the side chain. It has both the stability of inorganic silicon and the flexibility of organic groups. Its general structural formula can be expressed as: (R2SiO) n , wherein R is an organic group (such as -CH3, -C6H5, etc.). The organosilicon material has excellent high and low temperature resistance (long-term use at -60°C to 200°C), electrical insulation, weather resistance, chemical stability and low surface tension.

[0044] In this embodiment, the material of the fixed mesh 22 is set to carbon nanotubes or silicone materials with a surface resistance of 107~108Ω, so that the fixed mesh 22 has both porous and semi-conductive functions. The semi-conductive function means that the surface resistance of the material of the fixed mesh 22 is between that of a conductor and an insulator, and it has the function of conducting away charges, but the efficiency of conducting charges is lower than that of a conductor. Therefore, the fixed mesh 22 can be used as a structural member for placing and filling the catalyst 21, and can also be used as a grounding electrode to form a discharge structure with the discharge member 1 to achieve discharge between the inner wall of the through hole 11 and the surface of the catalyst 21, thereby increasing the plasma processing efficiency. At the same time, the fixed mesh 22 and the catalyst 21 occupy a small space, and the discharge device is highly integrated to reduce the overall size of the discharge device.

[0045] In one embodiment, the catalyst 21 comprises a nanomaterial noble metal catalyst 21 and a metal oxide composite catalyst 21 (not shown). Specifically, the nanomaterial noble metal catalyst 21 refers to nanoscale (1-100 nm) particles or structures made of noble metals (such as platinum (Pt), palladium (Pd), gold (Au), rhodium (Rh), etc.), having a high specific surface area and abundant surface active sites; the nanomaterial noble metal catalyst 21 has the characteristics of high catalytic activity, high selectivity, and challenging stability.

[0046] The metal oxide composite catalyst 21 refers to a multifunctional catalyst 21 based on metal oxides (such as TiO2, CeO2, Al2O3, Co3O4, etc.) and composited with other materials (such as precious metals, non-precious metals or carbon materials); the metal oxide composite catalyst 21 has a carrier function, a synergistic effect and multifunctionality.

[0047] In this embodiment, the catalyst 21 uses the nanomaterial noble metal catalyst 21 and the metal oxide composite catalyst 21. The nanomaterial noble metal catalyst 21 is known for its high activity and selectivity, while the metal oxide composite catalyst 21 further improves its performance through the carrier effect and synergistic effect. The combination of the two shows great potential in the fields of environmental protection, energy and chemical industry, making the catalyst 21 have better performance, higher catalytic efficiency and better efficiency in absorbing ozone.

[0048] More specifically, the catalyst 21 may be in powder or granular form, so as to be filled in the position of the fixing net 22 corresponding to the through hole 11 , so that the catalyst 21 can better absorb or decompose ozone generated during discharge.

[0049] In a specific embodiment, referring to Figure 1 、 Figure 3 and Figure 5 As shown, the discharge member 1 includes an insulating layer 12 and a metal electrode 13. The metal electrode 13 is arranged inside the insulating layer 12. The metal electrode 13 and the insulating layer 12 are both penetrated by the through hole 11, and the metal electrode 13 is electrically connected to the catalyst component 2.

[0050] Specifically, the discharge member 1 is used to pass high-voltage current and cooperate with the catalytic component 2 to form a discharge area. The discharge member 1 includes an insulating layer 12 and a metal electrode 13. The insulating layer 12 is used for insulation to prevent the outside of the discharge member 1 from being conductive, affecting the normal operation of the discharge member 1 and avoiding safety hazards; the metal electrode 13 is fixed inside the insulating layer 12, and the metal electrode 13 is electrically connected to one end of the power supply, and the other end of the power supply is electrically connected to the catalytic component 2. The metal electrode 13 and the catalytic component 2 have a conductive effect, so that the inner wall of the through hole 11 and the surface of the catalyst 21 form a discharge position to ionize the air to generate plasma.

[0051] At the same time, the insulating layer 12 and the metal electrode 13 are both penetrated by the through hole 11, that is, the through hole 11 penetrates the metal electrode 13 and the insulating layer 12 respectively, so that air can flow from one side of the discharge member 1 through the through hole 11, through the insulating layer 12 and the metal electrode 13 to the surface of the catalyst 21, and after ionization on the inner wall of the through hole 11 and the surface of the catalyst 21, plasma is generated, and pollutants are decomposed and treated, thereby ensuring the plasma treatment efficiency of the discharge device.

[0052] More specifically, the insulating material of the insulating layer 12 may be PCB, PTFE, ceramics, etc., and the material of the metal electrode 13 may be copper foil, aluminum foil, or other conductive metals.

[0053] More specifically, the overall shape of the discharge member 1 is not limited to a circle or a square. The through holes 11 are evenly distributed on the discharge member 1 , and the aperture of the through holes 11 ranges from 1 to 3 mm.

[0054] In a specific embodiment, referring to Figure 1 and Figure 3 As shown, the insulating layer 12 includes a first insulating layer 121 and a second insulating layer 122 that are fixedly connected. The first insulating layer 121 and the second insulating layer 122 are respectively located on both sides of the metal electrode 13 .

[0055] Specifically, the insulating layer 12 includes a first insulating layer 121 and a second insulating layer 122, and the first insulating layer 121 and the second insulating layer 122 are fixedly connected. The first insulating layer 121 and the second insulating layer 122 both have an insulating effect. The first insulating layer 121 and the second insulating layer 122 are respectively located on both sides of the metal electrode 13, that is, the metal electrode 13 is fixed between the first insulating layer 121 and the second insulating layer 122. The first insulating layer 121 and the second insulating layer 122 and the metal electrode 13 have the same shape and structure, thereby ensuring the structural stability of the discharge component 1. The first insulating layer 121 and the second insulating layer 122 perform a comprehensive insulating effect on the metal electrode 13 to ensure the normal operation of the discharge component 1 and reduce safety hazards.

[0056] More specifically, the first insulating layer 121 , the metal electrode 13 , and the second insulating layer 122 are sequentially arranged and integrally pressed to improve the structural stability of the discharge element 1 and increase the service life of the discharge element 1 .

[0057] In a specific embodiment, referring to Figure 5 As shown, the plurality of through holes 11 are spaced apart, and the edge distance between two adjacent through holes 11 is 1-4 mm. Specifically, the plurality of through holes 11 are spaced apart and evenly arranged on the discharge member 1, so that air can efficiently enter the spaced channels from the plurality of through holes 11 and be efficiently ionized.

[0058] In this embodiment, the edge distance between two adjacent through holes 11 is set to 1-4 mm, that is, the distance between the outer edges of two adjacent through holes 11 is 1-4 mm, so as to ensure that as many through holes 11 as possible are set on the discharge component 1, thereby improving the air intake efficiency of the discharge device, thereby improving the bactericidal and antibacterial efficiency, ensuring the structural strength of the discharge component 1, and improving the service life of the discharge component 1.

[0059] In one embodiment, referring to Figure 5As shown, there is a spacing between the edge of the through hole 11 and the metal electrode 13, and the spacing is 1-2.5mm. Specifically, the through hole 11 passes through the insulating layer 12 and the metal electrode 13, and the through hole 11 and the metal electrode 13 are spaced apart, that is, there is a certain distance between the metal electrode 13 and the outer edge of the through hole 11. The metal electrode 13 spacer ring is arranged on the outside of the through hole 11, and there is a spacing between the metal electrode 13 and the edge of the through hole 11. The spacing is set to 1-2.5mm. The specific value can be selected according to the area of the discharge element 1. Therefore, when the discharge element 1 is discharging at high voltage, a safe distance is provided between the insulating layer 12 and the metal electrode 13 to prevent creepage and improve safety.

[0060] In a specific embodiment, referring to Figure 1 and Figure 4 As shown, the discharge device further includes a carbon fiber electrode 3 , which is electrically connected to the catalytic component 2 . The carbon fiber electrode 3 and the catalytic component 2 form a back corona zone to decompose ozone and regenerate the catalyst 21 .

[0061] Specifically, the discharge device also includes a carbon fiber electrode 3, which is an electrochemical electrode made of carbon fiber as the core material. It uses the high conductivity, high specific surface area, chemical stability and mechanical strength of carbon fiber to serve as a medium or active interface for electron transfer in electrochemical reactions. Its structure usually includes a single or multiple bundles of carbon fibers (about 5 to 10 microns in diameter). After surface treatment (such as activation and functionalization), it can be directly used as a working electrode or composited with other materials. The carbon fiber electrode 3 has the characteristics of high conductivity, high specific surface area, chemical inertness, mechanical properties, and lightweight.

[0062] Therefore, the carbon fiber electrode 3 is electrically connected to the catalytic component 2, so that the carbon fiber electrode 3 and the catalytic component 2 form a back corona zone, the carbon fiber electrode 3 has a low corona onset voltage and a large stable discharge range; in the back corona zone, after the carbon fiber electrode 3 and the catalytic component 2 are energized, the catalytic component 2 will produce a back corona phenomenon, thereby generating active substances and increasing the temperature of the catalytic component 2, and then reacting or desorbing the pollutants adsorbed by the catalyst 21, thereby clearing the catalytic sites of the catalyst 21, realizing the regeneration of the catalyst 21, extending the service life of the catalyst 21, and reducing the cost of the discharge device.

[0063] After power is applied, the discharge of the catalytic component 2 will be accompanied by a temperature rise and the generation of active substances. Due to the instability of ozone and its strong oxidizing properties, ozone can be thermally desorbed and decomposed or the ozone can undergo an oxidation-reduction reaction to achieve further decomposition of ozone.

[0064] Therefore, in this embodiment, the carbon fiber electrode 3 and the catalytic component 2 generate a back corona phenomenon after power is applied, thereby completing the desorption and decomposition of ozone, achieving the regeneration of the catalyst 21 and the secondary decomposition of ozone, so as to further reduce the ozone concentration generated by the discharge device when treating polluted gases, thereby achieving the control and elimination of ozone concentration and improving user experience.

[0065] More specifically, the carbon fiber electrodes 3 and the fixed net 22 are electrically connected via a DC high voltage power supply to reduce costs.

[0066] This embodiment also provides a purification device (not shown in the figure), which includes a discharge device. The discharge device can adopt any discharge device provided by the present invention. Since the specific structure and working principle of the discharge device have been introduced in detail in the previous description, they will not be repeated here for the sake of brevity.

[0067] The purification equipment in this embodiment adopts the discharge device provided by the present invention. The discharge device is designed with the discharge member 1 of a porous discharge electrode, and the fixed mesh 22 of a porous carbon-based material with a surface resistance between that of a conductor and an insulator is selected. The fixed mesh 22 can be used as a structural member to place and fill the catalyst 21, and can also be used as a grounding electrode to form a DBD discharge structure with the discharge member 1 to achieve discharge in the electrode pores and on the surface of the catalyst 21, thereby increasing the plasma processing efficiency. It can also be integrated in a small size to make the purification equipment smaller and more integrated, suitable for purification of small spaces, and improve the applicability of the purification equipment.

[0068] At the same time, the discharge device can reduce the generation of ozone while decomposing pollutants in the air, avoiding excessive ozone concentration, thereby making the purification effect of the purification equipment better and improving user experience, while avoiding ozone from affecting equipment performance and increasing the service life of the purification equipment.
