Description

Technical Field

[0001] The present invention relates to the fields of environmental protection and medical hygiene, and in particular to a self-generated air purifier for removing solid particles, liquid particles, bacteria, viruses, pollen, etc. in the air. Background Art

[0002] In addition to traditional industrial dust removal, air purification technology also involves civilian indoor air purification. Traditional industrial dust removal generally collects polluted air through a dust hood, and then transports it to the purification unit through a pipe. The purified air is then pressurized by a fan and discharged through an exhaust duct (chimney). Although there is no obvious conveying pipeline in the indoor air purifier, there are fixed flow channels for polluted air and purified air, and the fan is still required to pressurize the air to purify the indoor air. Therefore, whether it is industrial dust removal or indoor air purification, no matter which purification form is used (the two most commonly used forms are the use of filter materials to retain particulate matter and the use of electrostatic adsorption to separate particulate matter), in addition to the core components of gas-solid / gas-liquid separation, an auxiliary fan and air duct system are also required, which directly increases the cost and space occupied by air purification.

[0003] Ion wind is a physical phenomenon that accompanies the high-voltage gas discharge process. It can produce side effects in the traditional air purification field, such as adverse disturbances to the flow field, increased system flow resistance, etc.

[0004] Ozone is a strong oxidant produced during high-voltage gas discharges. Industrially, ozone is widely used, such as in flue gas denitrification and sterilization in milk bottling plants. In civilian applications, ozone's strong permeability is primarily utilized for disinfection and sterilization indoors, particularly in damp, dark corners. Summary of the Invention

In addition, the air purifier of the present invention does not have the problem of secondary pollution caused by structures such as filter materials and air ducts, and can produce ozone of appropriate concentrations. Therefore, it has obvious advantages in the fields of indoor air purification, epidemic prevention in public places, and disinfection and sterilization of wards.

[0017] Other features and advantages of the present invention will be described in detail in the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

Together with the following detailed description, they are used to explain the present invention but do not constitute a limitation of the present invention. In the accompanying drawings:

[0023] 5 pairs of dust collecting electrodes DETAILED DESCRIPTION

[0024] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0025] refer to Figure 1 and Figure 2 The present invention provides a self-generated air purifier, which includes a discharge electrode 1, a dust collecting electrode 2 and a negative pressure component. Figure 1 This is a front view of an embodiment of a self-generated air purifier according to the present invention. Figure 2 : is a top view of an embodiment of a self-generated air purifier according to the present invention. For the sake of clarity, Figure 1 A portion of the dust collecting electrode 2 is removed to expose the obscured discharge electrode 1.

[0026] According to an embodiment of the present invention, when voltage is applied between the discharge electrode 1 and the collecting electrode 2, a gas discharge is generated. A high voltage can be applied to the discharge electrode 1 and the collecting electrode 2 via a DC high-voltage power supply. The collecting electrode 2 is electrically connected to the DC high-voltage power supply housing and is grounded. It is located on one side of the discharge electrode 1, spaced apart from the discharge electrode 1, and insulated from the discharge electrode 1. When a high voltage is applied to the discharge electrode 1 and the collecting electrode 2, an electric field is formed between them.

[0027] The electric field established by the discharge electrode 1 and the collecting electrode 2 according to the present invention utilizes the principle of directional migration of particles within a concentration gradient field to achieve effective charging, efficient agglomeration, and surface adsorption of particles with controlled residual charge. More specifically, once the electric field is established between the discharge electrode 1 and the collecting electrode 2, the particle concentration inside the field is very low due to the charging, agglomeration, and adsorption of the particles, while the particle concentration outside the field is higher. Consequently, the unbalanced impact force on external particles in this concentration gradient field causes a combined force inward, causing them to migrate into the interior and be adsorbed and separated.

[0028] Through the above, the present invention utilizes the principle of directional migration of particulate matter in a concentration gradient field, and without a conveying pipeline or a booster fan, the polluted air is moved, and the particulate matter is eventually effectively captured on the dust collecting electrode 2 and the discharge electrode 1. From the perspective of purification efficiency, since there are no conveying pipelines, booster fans and other structures in the embodiment of the present invention, it is more conducive to the coagulation of particulate matter before adsorption. This is crucial for improving the efficiency of adsorption separation. Experiments show that when the air purifier of the present invention has the same floor space (volume) as the air purifier of traditional technology, the purification efficiency is significantly higher.

[0029] Furthermore, the separation of the collecting electrode 2 and the discharge electrode 1 means that there is sufficient spacing between the collecting electrode 2 and the discharge electrode 1 to enable a DC voltage to be applied between the collecting electrode 2 and the discharge electrode 1 without arcing, thereby forming a stable electric field between the collecting electrode 2 and the discharge electrode 1 that charges, aggregates, and adsorbs particles. Furthermore, the collecting electrode 2 and the discharge electrode 1 can be insulated from each other through various structural arrangements, but consideration should be given to minimizing the effective area of ​​the collecting electrode 2 and the discharge electrode 1 occupied by the insulating structure, thereby maximizing the purification efficiency of the electric field.

[0030] In addition, according to an embodiment of the present invention, the self-generating air purifier further includes a negative pressure component, which is arranged on the other side of the discharge electrode 1 and forms a self-generating wind zone with the dust collecting electrode 2. For the convenience of description below, the side of the discharge electrode 1 where the dust collecting electrode 2 is arranged is referred to as the first side of the discharge electrode 1, for example Figure 2 The side below the discharge electrode 1; the side of the discharge electrode 1 provided with the negative pressure component is called the second side of the discharge electrode 1, for example Figure 2 The upper side of the middle discharge electrode 1. It should be noted that such description is only for illustration and not for limitation.

[0031] When the electric field is established, ion wind is generated along with the gas discharge. In the prior art, since ion wind is difficult to control, it has been rarely used so far. The present invention guides the flow of ion wind generated by gas discharge by providing a negative pressure component on the second side of the discharge electrode 1, so that a negative pressure zone is formed on the second side of the discharge electrode 1, and a self-generated wind zone is formed in the area formed by the negative pressure component and the dust collecting electrode 2. In this way, external air is continuously replenished to the negative pressure zone, and then continuously flows from the negative pressure zone to the discharge electrode 1 and the dust collecting electrode 2, and then flows out of the air purifier, thereby forming a continuous air flow similar to that when there is a fan inside the air purifier.

[0032] As described above, the present invention utilizes the self-generated wind generated by a suitably designed electric field structure to promote the faster flow of particulate matter from a high-concentration location outside the air purifier to the inside of the air purifier, thereby increasing the purification speed.

[0033] In summary, the present invention cleverly connects the concentration gradient field and the electromagnetic fluid field to make the air within the control range of the air purifier move without a fan or air duct. When the polluted air passes through the self-generated air purifier, the solid particles and liquid particles therein are separated out by adsorption. According to the above, the self-generated air purifier of the present invention not only improves the purification efficiency, but also greatly simplifies the structural setting of the traditional air purifier. In addition, since the air purifier of the present invention does not have the problem of secondary pollution caused by structures such as filter materials and air ducts, and can produce ozone of appropriate concentration, it can not only separate particulate matter, bacteria and viruses, but also kill bacteria and viruses in spaces or corners. Therefore, it has obvious advantages in the fields of indoor air purification, epidemic prevention in public places, and disinfection and sterilization of wards.

[0034] Continue to refer Figure 1 and Figure 2 According to a preferred embodiment of the present invention, the negative pressure assembly includes an auxiliary dust collecting electrode 5 spaced apart from the discharge electrode 1. Similar to the above, the auxiliary dust collecting electrode 5 and the discharge electrode 1 are spaced apart, which means that there is a sufficient distance between the auxiliary dust collecting electrode 5 and the discharge electrode 1 so that arcing breakdown does not occur between the auxiliary dust collecting electrode 5 and the discharge electrode 1.

[0035] In traditional electrostatic precipitators, the collecting electrode plates on both sides of the discharge electrode line are arranged symmetrically, and the present invention has improved this. According to an embodiment of the present invention, the interval between the auxiliary collecting electrode 5 and the discharge electrode 1 is greater than the interval between the collecting electrode 2 and the discharge electrode 1. That is to say, the present invention arranges the collecting electrodes 2 and the auxiliary collecting electrodes 5 on both sides of the discharge electrode 1 in an asymmetric form. For ease of description, the spacing between the discharge electrode 1 and the collecting electrode 2 will be referred to as a narrow asymmetric distance, and the spacing between the discharge electrode 1 and the auxiliary collecting electrode 5 will be referred to as a wide asymmetric distance. It should be understood that such a description is illustrative, not restrictive. Reference Figure 2 The narrow polarity is labeled h1, and the wide polarity is labeled h2, where h2>h1. According to the present invention, the asymmetrical distribution of polarity on both sides of the discharge electrode 1 generates a continuous air flow from the wide polarity side to the narrow polarity side. During this process, particulate matter in the air is adsorbed and separated, achieving air purification.

[0036] In addition, according to a preferred embodiment of the present invention, the dust collecting electrode 2 and the auxiliary dust collecting electrode 5 are connected and enclosed together to form a self-generated wind zone, and the discharge electrode 1 is fixed in the self-generated wind zone by the insulating bracket 3.

[0037] The dust collecting electrode 2 and the auxiliary dust collecting electrode 5 are connected and enclosed together, and the air continuously flows from the wide differential pole side to the narrow differential pole side, so that a negative pressure zone can be formed on the wide differential pole side. External air can be continuously added to the negative pressure zone, and then flow out of the air purifier from the narrow differential pole side, thereby forming a self-generated wind zone between the dust collecting electrode 2 and the auxiliary dust collecting electrode 5. Due to the direction of air flow, particulate matter is mainly adsorbed on the dust collecting electrode 2, and the auxiliary dust collecting electrode 5 plays an auxiliary purification role. According to an embodiment of the present invention, the dust collecting electrode 2 and the auxiliary dust collecting electrode 5 can be made of the same material or different materials. The dust collecting electrode 2 and the auxiliary dust collecting electrode 5 connected together can form the outer shell of the self-generated wind air purifier, which plays a safety protection role on the first side and the second side of the discharge electrode 1, respectively. According to an embodiment of the present invention, the dust collecting electrode 2 and the auxiliary dust collecting electrode 5 can be grounded as a whole to ensure the safety of the air purifier.

[0038] The discharge electrode 1 is fixed in the self-generated wind zone by an insulating bracket 3. The insulating bracket 3 is an insulating component when the different poles are connected to form an integral device, thereby ensuring that the air purifier will not be broken down inside and the surface will not be creeped under any temperature and humidity conditions.

[0039] In addition, in conventional electrostatic precipitators, the collecting plates on both sides of the discharge electrode are solid plate structures. The solution of the present invention can be applied to scenarios where the collecting plates are solid plate structures. However, the present invention also provides preferred embodiments in which the collecting electrode 2 and the auxiliary collecting electrode 5 are mesh structures and / or louver grille structures to improve the existing structure.

[0040] The through holes on the dust collecting electrode 2 and the auxiliary dust collecting electrode 5 contribute to the directional migration of particulate matter, and a portion of the particulate matter outside the electric field can be directly adsorbed on the dust collecting electrode 2 and / or the auxiliary dust collecting electrode 5 during the directional migration process, rather than having to be adsorbed and separated after entering the electric field. The through holes on the dust collecting electrode 2 and the auxiliary dust collecting electrode 5 also contribute to the continuous flow of ion wind in the self-generated wind zone, and when the ion wind carries particulate matter through the through holes of the dust collecting electrode 2 and flows, the dust collecting electrode 2 can capture more particulate matter, thereby improving the purification efficiency. The through holes on the dust collecting electrode 2 and the auxiliary dust collecting electrode 5 also contribute to its own cleaning, and the particulate matter adsorbed on the surface and inside of the air purifier can be cleaned up by directly flushing and / or vibrating the dust removal device.

[0041] Continue to refer Figure 1 and Figure 2 According to a preferred embodiment of the present invention, the negative pressure assembly includes an insulating sheath (not shown), and the discharge electrode 1 is fixedly connected to the insulating sheath.

[0042] The insulating sheath is provided on the second side of the discharge electrode 1, and it can be understood that it is formed by an insulating material. Based on its insulating properties, the discharge electrode 1 is fixedly connected thereto. In this way, when the electric field between the discharge electrode 1 and the dust collecting electrode 2 is established, due to the gas discharge between the discharge electrode 1 and the dust collecting electrode 2, the ion wind flows from the direction of the insulating sheath to the direction of the dust collecting electrode 2, thereby forming a negative pressure zone between the discharge electrode 1 and the insulating sheath and around the discharge electrode 1. External air is continuously added to the negative pressure zone, and then discharged from the area close to the dust collecting electrode 2 to the outside of the air purifier (when the dust collecting electrode 2 is a solid plate), or directly discharged from the through hole of the dust collecting electrode 2 to the outside of the air purifier, thereby forming a self-generated wind zone between the dust collecting electrode 2 and the insulating sheath.

[0043] Furthermore, according to a preferred embodiment of the present invention, a portion of the discharge electrode 1 is embedded in the insulating sheath, while the other portion is exposed toward the dust collecting electrode 2. This allows the insulating sheath to serve as part of the insulating bracket 3, strengthening the robustness of the discharge electrode 1 and reducing the difficulty of insulating the insulating bracket 3. In this embodiment, the side of the insulating sheath opposite the side to which the discharge electrode 1 is secured may not have the discharge electrode 1 exposed, thereby allowing the discharge electrode 1 to serve as the outer shell of the air purifier and provide safety protection. More preferably, the discharge electrode 1 has a pointed tip, which is exposed toward the dust collecting electrode 2. This creates a tip discharge, resulting in better particle charging and a stronger ion wind. The tip of the discharge electrode 1 can be achieved using a barbed wire or a star-shaped wire.

[0044] In addition, according to a preferred embodiment of the present invention, a plurality of vents are formed on the insulating sheath. When ion wind is formed in the electric field, external air can be supplied to the negative pressure area through the vents on the insulating sheath, thereby promoting air flow in the electric field.

[0045] Still refer to Figure 1 and Figure 2 According to a preferred embodiment of the present invention, the negative pressure assembly includes an insulating sheath (not shown) and an auxiliary dust collecting electrode 5. The discharge electrode 1 is fixedly connected to the insulating sheath, and the auxiliary dust collecting electrode 5 is arranged spaced apart from the insulating sheath. All the embodiments of the insulating sheath and the auxiliary dust collecting electrode 5 described above are applicable to this embodiment and will not be repeated here. The only difference is that, in this embodiment, the interval between the auxiliary dust collecting electrode 5 and the discharge electrode 1 does not necessarily have to be greater than the interval between the dust collecting electrode 2 and the discharge electrode 1. That is to say, in this embodiment, the interval between the auxiliary dust collecting electrode 5 and the discharge electrode 1 may also be equal to or less than the interval between the dust collecting electrode 2 and the discharge electrode 1.

[0046] Furthermore, according to an embodiment of the present invention, the discharge electrode 1 has a linear or mesh structure. The discharge electrode 1 can be a point discharge structure such as a barbed wire, a linear discharge structure such as a star-shaped wire, or a surface discharge structure such as a circular wire. It can also be formed into a grid or mesh structure. The discharge electrode 1 can be made of metal or other conductive materials such as carbon fiber.

[0047] According to the above, the appearance of the self-generated air purifier of the present invention can be designed to be like a thick filter mesh, and its size and thickness can be changed according to the application.

[0048] Taking workshop air purification as an example, its specific dimensions can be determined based on the size of the area to be purified. A self-generating air purifier can be placed between two pillars. When the air purifier is operating, air is drawn in on one side and blown out on the other side. Because the air pressure outside the purifier's controlled area tends to be balanced, the jet flow on the purifier's outlet side and the entrained ambient air eventually flow back from the edge of the controlled area to the purifier's intake side, forming a continuous cycle. In this process, the air within the entire controlled area is purified as it passes through the purifier.

[0049] Taking indoor air purification as an example, a self-generating air purifier is placed on the wall at a certain distance. When the purifier is operating, the appropriate concentration of ozone produced can kill bacteria and viruses in the room, including in corners and crevices. Bacteria and viruses not killed by the ozone are drawn into the electric field and killed there. These killed bacteria and virus particles, along with PM2.5 and other particles in the air, are adsorbed on the purifier and removed when the purifier is cleaned. The clean air flow from the purifier will absorb the polluted air in the room and then return to the purifier from the other side due to the trend of spatial pressure equilibrium, completing the purification cycle.

[0050] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the scope of protection of the present invention.

[0051] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. To avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0052] In addition, the various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
