Description

Technical Field

[0001] This invention belongs to the field of air purification, and in particular relates to a modular flying net device for atmospheric haze removal. Background Technology

[0002] With the continuous advancement of industrialization, atmospheric particulate matter pollution, especially high-concentration particulate matter emitted from industrial areas, not only damages the ecological environment but also poses a threat to human health. Therefore, the control of atmospheric particulate matter has become an important issue in the field of environmental protection. Currently, the industry's methods for controlling atmospheric particulate matter are relatively traditional, mainly relying on three approaches: ground-based source emission reduction, fixed electrostatic precipitators, and artificial rain enhancement. While these methods have been promoted to some extent in practical applications, long-term practical experience has shown that they all have inherent defects that are difficult to overcome. As a result, the control effects are insufficient to meet the requirements of industrial production and environmental compliance, and large-scale commercial applications are also difficult to achieve.

[0003] Ground-based emission reduction methods mainly control particulate matter by controlling the emission intensity of pollution sources. However, they have significant shortcomings when dealing with high-concentration, fugitive particulate matter emissions from industrial areas. On the one hand, the sources of fugitive particulate matter emissions in the atmosphere are dispersed and the emission paths are not fixed, requiring a large amount of manpower and resources for comprehensive management, resulting in high treatment costs. On the other hand, due to limitations in the scope and precision of management, even with high costs, it is difficult to achieve efficient removal of particulate matter, and the treatment effect is very limited, failing to meet the stringent environmental emission requirements of industrial areas.

[0004] Fixed electrostatic precipitators are currently the most widely used dust removal equipment in the industrial field. Their core principle is to capture particulate matter through electrostatic adsorption. However, their application scenarios are strictly limited; they are only suitable for particulate matter control in enclosed spaces and cannot cover open spaces such as open work areas and open storage yards. Since a large amount of particulate matter emissions originate from the unorganized diffusion in open spaces, the application scope of fixed electrostatic precipitators is greatly limited, making it difficult to achieve comprehensive particulate matter control in industrial areas.

[0005] Artificial rain enhancement involves human intervention in meteorological conditions to remove particulate matter through precipitation. However, its effectiveness depends entirely on natural meteorological conditions and is subject to various meteorological factors such as cloud thickness, water vapor content, and temperature, resulting in significant uncertainty. Under unfavorable meteorological conditions such as drought or low cloud cover, artificial rain enhancement cannot be implemented, leading to a standstill in particulate matter control efforts and preventing the achievement of stable, all-weather control results.

[0006] In summary, existing methods for controlling particulate matter in the atmosphere all have inherent limitations. Neither alone nor in combination can effectively address the challenge of controlling high concentrations of fugitive particulate matter emissions in the atmosphere. Furthermore, issues such as high costs, narrow applicability, and unstable effectiveness hinder the commercialization of these technologies and prevent them from meeting the demands for large-scale, efficient, and low-cost particulate matter control. Therefore, developing a novel air pollution control method that overcomes these limitations, is adaptable to complex control scenarios, and possesses commercial application potential has become a pressing technical problem for those skilled in the art. Summary of the Invention

[0007] In view of this, the present invention provides a modular aerial net device for atmospheric haze removal. This device uses an aircraft to suspend and fully deploy the haze removal net in the air, ensuring the net surface is stably facing the oncoming wind direction. This allows for efficient interception and capture of various pollutant particles carried in the airflow. Simultaneously, a discharge module can create a directional electric field on the haze removal net, causing pollutant particles to gather in a designated direction, preventing large accumulations of pollutant particles in the central area of ​​the net, which could lead to net blockage and reduced ventilation.

[0008] The technical solution adopted in this invention is as follows:

[0009] A modular aerial net device for atmospheric haze removal includes:

[0010] A smog-removing net is used to adsorb suspended pollutant particles in the air and has electrical conductivity.

[0011] The aircraft is equipped with multiple units, each connected to the top corner and center of the smog removal net, for the deployment and attitude control of the smog removal net in the air;

[0012] At least one discharge module is installed on the aircraft, and the discharge module is electrically connected to the smog removal network.

[0013] When the discharge module is working, it can form a directional electric field on the smog removal network to directionally migrate the pollutant particles captured by the network.

[0014] Furthermore, the smog removal net is composed of several conductive adsorption net units spliced ​​together.

[0015] Furthermore, the adsorption mesh unit is made of graphene-based materials.

[0016] Furthermore, the smog removal net is also equipped with a fixing frame for connecting each adsorption net unit. The fixing frame has several installation ports distributed in an array. Each adsorption net unit corresponds to one installation port and is assembled in the corresponding installation port.

[0017] Furthermore, the fixing frame is conductive, and electrical contacts for connecting the discharge module are respectively provided in the middle area and at the edge of the fixing frame. The surface of the electrical contacts is coated with an anti-oxidation layer.

[0018] Furthermore, the fixed frame and the adsorption net unit are detachably connected by mechanical snap-fit.

[0019] Furthermore, when only a single discharge module is installed, the discharge module is electrically connected to the center of the smog removal net and can release high-voltage negative charges to the central area of ​​the smog removal net. The edges of the smog removal net are grounded, thereby forming a directional electric field radiating from the center to the surrounding areas on the surface of the smog removal net.

[0020] Furthermore, when multiple discharge modules are configured, each aircraft carries one discharge module. One discharge module is electrically connected to the center of the smog removal net and can release high-voltage negative charges to the central area of ​​the smog removal net. The remaining discharge modules are connected to the edge of the smog removal net and can release low-voltage positive charges to the edge of the smog removal net, thereby forming a directional electric field radiating from the center to the surrounding areas on the surface of the smog removal net.

[0021] Furthermore, the aircraft is a tethered airship.

[0022] Furthermore, each aircraft is equipped with a wind power generation module and an energy storage battery. The wind power generation module is electrically connected to the energy storage battery, and the energy storage battery is electrically connected to the discharge module.

[0023] The beneficial effects of this invention compared to the prior art are:

[0024] 1. The smog removal net of the present invention can be suspended in the air by an aircraft and fully deployed under the coordinated pulling action of multiple aircraft, so that the net surface is stably facing the direction of the oncoming wind, and can efficiently intercept and capture various pollutant particles carried in the airflow.

[0025] Meanwhile, the discharge module creates a directional electric field on the smog removal net, causing particulate matter to concentrate in a designated direction. This prevents large accumulations of pollutants in the central area of ​​the net, which could lead to blockage and poor ventilation. This design maintains the net's permeability and airflow over the long term, ensuring continuous and stable large-scale smog removal operations and improving the actual purification effect of the aerial net device. Furthermore, when a large amount of pollutants accumulates at the edge of the net, the aircraft can be brought to the ground. After disconnecting the power and voltage, the adsorbed pollutants will detach from the net, allowing for centralized collection and easier subsequent processing.

[0026] 2. The smog removal net of the present invention is designed with a fixed frame, and the electrical contacts are designed on the fixed frame instead of the adsorption net unit itself. This eliminates the trouble of setting electrical contacts on each adsorption net unit, reduces design and manufacturing costs, avoids damage to electrical contacts during the cleaning process of the adsorption net unit, extends the service life of the adsorption net unit, and ensures the stability and reliability of the electrical connection between the discharge module and the smog removal net, ensuring the long-term stable operation of the smog removal net.

[0027] 3. The fixed frame and the adsorption net unit of the present invention are detachably connected, which facilitates the quick assembly and disassembly of the two.

[0028] 4. The aircraft of the present invention is equipped with a wind power generation module and an energy storage battery. The wind power generation module can capture wind energy resources at high altitudes and convert them into electrical energy, which is stored in the energy storage battery in real time. The electrical energy stored in the energy storage battery is used to power the discharge module, eliminating the need for an additional battery to power the discharge module. This maximizes the utilization rate of high-altitude wind energy and achieves the rational allocation and recovery of energy. Attached Figure Description

[0036] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] This embodiment provides a modular flying net device for atmospheric haze removal, which mainly targets the efficient interception and enrichment of pollutant particles such as haze and dust suspended in the air, thereby achieving the purpose of large-scale air purification and long-term haze removal.

[0038] Combination Figure 1 and Figure 2 As shown, the modular aerial net device mainly consists of a smog removal net 1, aircraft 2, and a discharge module. The smog removal net 1 adopts a modular design and is conductive. It is composed of several adsorption net units 12, which can be replaced according to usage requirements. The adsorption net units 12 are used to physically adsorb fine pollutant particles suspended in the air, completing basic smog interception operations. Multiple aircraft 2 are configured. To ensure the stable deployment and controllable attitude of the smog removal net 1 in the air, the aircraft 2 and the smog removal net 1 are connected by a zoned pulling method. That is, one aircraft 2 is fixedly connected to the center of the smog removal net 1, while the other aircraft 2 are respectively connected to the various corners of the smog removal net 1. Through multi-point synchronous pulling, the smog removal net 1 is fully stretched and flattened in the air, maintaining a stable operational coverage area. At least one discharge module is configured. When only a single discharge module is configured, it is mounted on the aircraft 2 connected to the center of the smog removal net 1. The discharge module is electrically connected to the central area of ​​the smog removal net 1 via a wire, and the edge area of ​​the smog removal net 1 is grounded. When the discharge module is working, it can continuously release high-voltage negative charges to the central area of ​​the smog removal net 1, thereby forming a directional electric field on the smog removal net 1. The high-voltage negative charge breaks down the surrounding air, forming a corona discharge, ionizing the surrounding air, and forcing pollutant particles passing through the smog removal net 1 to carry a negative charge. Under the action of this electric field, the pollutant particles initially captured and fixed by the adsorption net will undergo directional migration, continuously and orderly accumulating from the central area of ​​the smog removal net 1 to the surrounding edges, ensuring the permeability of the central area of ​​the smog removal net 1. When multiple discharge modules are configured, each aircraft 2 is equipped with one discharge module. The discharge module on the central aircraft 2 is electrically connected to the central position of the smog removal net 1 through a wire. During operation, it can continuously release high-voltage negative charges to the central area of ​​the smog removal net 1. The discharge modules on each corner aircraft 2 are electrically connected to the edge area of ​​the smog removal net 1 through wires, and can continuously release low-voltage positive charges to the edge of the smog removal net 1. Through the differentiated charge arrangement of negative charges in the central area and positive charges in the edge area, a continuous and stable directional electric field can be formed within the coverage area of ​​the entire smog removal net 1.

[0039] In this embodiment, the smog removal net 1 can be suspended in the air and deployed by an aircraft 2. With the coordinated pulling action of multiple aircraft 2, it fully unfolds, ensuring the net surface is stably facing the oncoming wind direction, effectively intercepting and capturing various pollutant particles carried in the airflow. Simultaneously, through the installation of a discharge module, a directional electric field is formed on the smog removal net 1, causing pollutant particles to gather in a designated direction, preventing a large accumulation of pollutant particles in the central area of ​​the net 1, which would lead to net blockage and reduced ventilation. This design maintains the permeability and airflow of the smog removal net 1 over a long period, ensuring its continuous and stable large-scale atmospheric smog removal operations and improving the actual purification effect of the aerial net device. At the same time, it reduces the accumulation of particles in the center of the smog removal net 1, extending the single cleaning cycle. In practical use, multiple aerial net devices can be set up to remove smog from a specific area in rotation. When a large number of pollutant particles accumulate on the edge of the net 1 of one aerial net device, the aircraft 2 of that device can be controlled to land on the ground, while another backup aerial net device is activated to ascend into the air for smog removal. The number of backup aerial net devices can be determined according to usage requirements. After the aircraft 2 controls the aerial net 1 to land, the power supply to the discharge module is disconnected, and the voltage is released. The pollutant particles adsorbed on the aerial net 1 will then fall off automatically, thus achieving centralized collection of pollutant particles for convenient subsequent processing. The aerial net 1 can be washed and reused repeatedly, saving costs.

[0040] In this embodiment, the adsorption mesh unit 12 has a porous structure, specifically a regularly arranged array of pores. These pores can be square, triangular, hexagonal, or honeycomb-like, with a pore size of 1-5 cm and a porosity of 50%-90%. The adsorption mesh unit 12 can be made of various graphene-based materials. Graphene has excellent electrical conductivity and can be used in conjunction with a discharge module to achieve electro-adsorption, capturing airborne particulate matter. Simultaneously, the adsorption mesh unit 12 can utilize graphene foam, graphene aerogel, or graphene composite fibers. These materials, leveraging graphene's excellent specific surface area and adsorption performance, can enhance the adsorption mesh unit 12's efficiency in capturing airborne particulate matter, meeting the operational requirements of the smog removal mesh 1. The graphene composite fiber material can be obtained through a substrate material and graphene modification. The substrate material includes, but is not limited to, carbon fiber, glass fiber, and various polymer fibers. In actual production, suitable substrate materials can be flexibly selected according to the application scenario and mechanical performance requirements of the adsorption mesh unit 12. The substrate materials are then modified by surface coating or doping with graphene. Surface coating allows graphene to be uniformly attached to the surface of the substrate fibers, giving full play to the adsorption characteristics of graphene. Doping integrates graphene into the interior of the substrate material, further enhancing the overall adsorption capacity and structural stability of the fibers. This ensures that the adsorption mesh unit 12 made of graphene composite fibers possesses both the mechanical strength of the substrate material and the excellent adsorption performance of graphene, meeting the requirements for long-term stable operation of the smog removal mesh 1.

[0041] Combination Figure 3 As shown, to extend the service life of the smog removal net 1, the smog removal net 1 in this embodiment is also provided with a fixing frame 11 for connecting each adsorption net unit 12. The fixing frame 11 is conductive and serves as the installation carrier and structural support for the entire smog removal net 1. Its surface has several mounting ports evenly distributed in an array. Each adsorption net unit 12 corresponds precisely to one mounting port and is assembled in the corresponding mounting port using a detachable structure. This detachable design greatly facilitates the individual maintenance and replacement of the adsorption net unit 12. At the same time, electrical contacts are provided in the middle area and at the edge of the fixing frame 11. These electrical contacts are used to connect to the discharge module, providing power support for the adsorption function of the entire smog removal net 1.

[0042] Because the discharge module and the smog removal net 1 need to be connected by wires to form a directional electric field on the surface of the net 1, directly connecting the discharge module to each adsorption net unit 12 would require setting electrical contacts on each adsorption net unit 12 individually. This would not only increase the design complexity of the adsorption net unit 12 itself, but also increase the difficulty of the manufacturing process and increase manufacturing costs. More importantly, during the long-term use of the smog removal net 1, the adsorption net unit 12 will continuously adsorb pollutant particles in the air. Even after the equipment is powered off, most particles will fall off due to gravity, but some particles will still adhere to the surface of the adsorption net unit 12 and must be cleaned to remove them completely. After repeated cleaning, the electrical contacts on the surface of the adsorption net unit 12 are prone to oxidation, poor contact, or even complete damage, which will prevent the adsorption net unit 12 from working properly and significantly shorten its service life. Therefore, in this embodiment, the electrical contacts are designed on the fixed frame 11, rather than on the adsorption net unit 12 itself. This not only eliminates the trouble of setting electrical contacts on each adsorption net unit 12, reducing design and manufacturing costs, but also avoids damage to the electrical contacts during the cleaning process of the adsorption net unit 12, extending the service life of the adsorption net unit 12. At the same time, it can also ensure the stability and reliability of the electrical connection between the discharge module and the smog removal net 1, ensuring the long-term stable operation of the smog removal net 1.

[0043] The fixed frame 11 and the adsorption net unit 12 can be detachably connected by a mechanical buckle 13. The mechanical buckle 13 can be made of a high-strength, corrosion-resistant and conductive material, including but not limited to stainless steel, aluminum alloy, carbon fiber composite material, etc.

[0044] Furthermore, combined Figure 4The structure shown in this embodiment uses a mechanical snap-fit ​​13, specifically a snap-fit ​​structure. This snap-fit ​​consists of a male snap-fit ​​131 and a female snap-fit ​​132 that cooperate with each other to achieve a detachable connection between the fixing frame 11 and the adsorption net unit 12, providing convenient operation and a stable connection. In the specific assembly design, several male snap-fits 131 are arranged and fixed along the edge of the mounting opening of the fixing frame 11; each male snap-fit ​​131 corresponds to one female snap-fit ​​132, and the corresponding female snap-fit ​​132 is installed at the edge of the adsorption net unit 12. The installation positions of the two are one-to-one, ensuring precise alignment during assembly. When the adsorption net unit 12 needs to be installed on the fixed frame 11, simply align the adsorption net unit 12 with the installation port, gently press the edge of the adsorption net unit 12, and make the female buckle 132 precisely engage with the male buckle 131 on the fixed frame 11 to complete the quick assembly of the two. When the adsorption net unit 12 needs to be disassembled for cleaning, maintenance or replacement, simply pry the edge of the adsorption net unit 12 gently to separate the male buckle 131 from the female buckle 132, and the adsorption net unit 12 can be easily taken out from the installation port of the fixed frame 11. The entire disassembly and assembly process does not require any tools, taking into account the stability of the connection and the convenience of operation, and adapting to the usage needs of the adsorption net unit 12 which requires frequent disassembly and maintenance.

[0045] To ensure stable conductivity of the electrical contacts on the fixed frame 11 and reliable electrical connection between the discharge module and the smog removal network 1, the electrical contacts in this embodiment are all made of highly conductive materials. The selected materials include, but are not limited to, copper, silver, copper-silver alloys, copper-tin alloys, and other alloy materials. These materials possess extremely low resistance and excellent conductivity, enabling efficient power transmission, reducing energy loss during current transmission, and meeting the operational requirements of the smog removal network 1.

[0046] Furthermore, considering that electrical contacts are exposed to air for extended periods and are susceptible to oxidation from moisture, dust, and other impurities, leading to poor contact, decreased conductivity, or even damage, thus affecting the normal operation of the entire smog removal network 1, an anti-oxidation layer can be plated onto the surface of the electrical contacts. This anti-oxidation layer effectively isolates the contact material from air and moisture, inhibiting oxidation without affecting conductivity, thus extending the contact's lifespan and ensuring long-term stable conductivity, thereby guaranteeing the continuous and reliable operation of the smog removal network 1.

[0047] Furthermore, after the smog removal net is launched, if an emergency response scenario occurs, such as damage to a certain adsorption net unit, a drone can be released to carry a new adsorption net unit to the damaged adsorption net unit. This design can shorten the replacement time of the adsorption net unit.

[0048] Combination Figure 1 andFigure 2 As shown, the aircraft 2 used in this embodiment is specifically a tethered airship. This tethered airship serves as a carrier for high-altitude wind energy utilization. Each airship is equipped with a wind power generation module and an energy storage battery. The wind power generation module is electrically connected to the energy storage battery, and the energy storage battery is electrically connected to the discharge module. The overall operating altitude of the tethered airship can cover 200–2000m, allowing the wind power generation module to capture wind energy resources at altitudes of 200–2000 meters and convert them into electrical energy, which is then stored in the energy storage battery in real time. The power generation capacity of a single tethered airship ranges from 10–100kW, enabling stable power generation based on changes in high-altitude wind speed. The energy storage battery has a capacity of 5–20kWh, allowing it to store surplus power generation in real time and supply power to the discharge module. Excess electricity generated by the wind power generation module can also be transmitted to the ground via a tethered cable. The tethered cable integrates a high-voltage direct current transmission unit, which can stably boost the voltage of the excess power and safely and efficiently transmit it to the ground power supply network, realizing grid-connected utilization of electricity, maximizing the utilization rate of high-altitude wind energy, and achieving rational energy allocation and recycling.

[0049] Example 1:

[0050] A tethered airship system was deployed under prevailing wind conditions. The airship itself was a square structure, 150m x 150m in size, composed of several 10m x 10m adsorption net units with 3cm pores. The system consisted of five tethered airships and one discharge module. One tethered airship was connected to the center of the airship and carried the discharge module, which was electrically connected to the center of the airship via wires. The remaining four tethered airships were fixed at the four corners of the airship.

[0051] Each tethered airship is equipped with a wind power generation module and an energy storage battery. The wind power generation module is electrically connected to both the discharge module and the energy storage battery, and the energy storage battery is electrically connected to the discharge module. The wind power generation module has a power output of 50kW, and the energy storage battery has a capacity of 10kWh. The tethered airship ascends to an altitude of 800 meters, utilizing stable high-altitude wind energy. The wind power generation module continuously generates electricity to power the discharge module and the energy storage battery. When there is surplus power, the excess energy is transmitted to the ground power grid through a tethered cable containing a 10kV DC transmission unit for use by ground users. When wind power is insufficient, the energy storage battery automatically powers the discharge module to ensure its continuous operation.

[0052] During operation, the discharge module at the center of the dust removal net releases a negative high voltage of 30-50kV, while the corners are grounded. According to electrostatic field theory, under the conditions of applying a negative high voltage at the center and grounding at the four corners, a divergent electric field will be formed inside the dust removal net, radiating outwards from the center. The electric field strength near the center is relatively high, reaching 2-3kV / cm, sufficient to generate corona discharge and charge the flowing pollutant particles. The electric field strength near the corners is relatively low, about 0.5-1kV / cm, which meets the adsorption requirements. This electric field distribution can effectively drive charged particles to the surrounding areas, preventing premature blockage in the central area and extending the single cleaning cycle.

[0053] In this embodiment, the flying net device operates for 10 to 20 days as one work cycle. After the cycle ends, the entire device is lowered down, the adsorption net unit is replaced, and after cleaning and maintenance, it is taken up again to carry out air removal and haze removal operations in a cyclical manner.

[0054] Example 2:

[0055] Three sets of aerial netting devices were deployed under prevailing wind conditions. Each set of aerial netting devices features a rectangular net structure, with an overall size of 200m × 100m, composed of several 10m × 10m adsorption net units, each with a pore size of 5cm. The aerial netting device is equipped with seven tethered airships and seven sets of discharge modules. One tethered airship is connected to the center of the aerial netting, and its discharge module is electrically connected to the center of the netting via a power line. The remaining six tethered airships are connected to the four corners and the center of the two long sides of the aerial netting, respectively. The discharge modules on these six tethered airships are electrically connected to the corners and the center of the two long sides of the netting via wires.

[0056] Each tethered airship is equipped with a wind power generation module and an energy storage battery. The wind power generation module is electrically connected to both the discharge module and the energy storage battery, and the energy storage battery is electrically connected to the discharge module. The wind power generation module has a power output of 100kW, and the energy storage battery has a capacity of 20kWh. The tethered airship ascends to an altitude of 1200 meters, utilizing stable high-altitude wind energy. The wind power generation module continuously generates electricity to power the discharge module and the energy storage battery. When there is surplus power, the excess energy is transmitted to the ground power grid via a tethered cable containing a 10kV DC transmission unit for use by ground users. When wind power is insufficient, the energy storage battery automatically powers the discharge module to ensure its continuous operation.

[0057] During operation, the discharge module at the center of the dust removal net releases a negative high voltage of 30-50kV, while the discharge modules at the top corners and the centers of the two long sides release low-voltage positive charges. According to electrostatic field theory, under the conditions of applying a negative high voltage at the center and low-voltage positive charges at the four corners, a divergent electric field will be formed inside the dust removal net, radiating outwards from the center. The electric field strength near the center is relatively high, reaching 2-3kV / cm, sufficient to generate corona discharge and charge the flowing pollutant particles. The electric field strength near the top corners is relatively low, about 0.5-1kV / cm, which meets the adsorption requirements. This electric field distribution can effectively drive charged particles to the surrounding areas, preventing premature blockage in the central area and extending the single cleaning cycle.

[0058] In this embodiment, each set of aerial netting devices operates for 15 days as one work cycle. After the cycle ends, the entire device lands, and simultaneously, another set of aerial netting devices is activated to remove haze. One set of aerial netting devices remains as a backup. After landing, the haze removal net 1 is powered off, and the adsorption net unit is disassembled, cleaned, and dried for backup. It can be used repeatedly for air haze removal operations.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions created by the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions created by the present invention without departing from the essence and scope of the technical solutions created by the present invention.
