Description

Technical Field

[0001] This utility model relates to the field of atmospheric condensate collection technology, specifically to a zero-carbon atmospheric condensate collection device for open-pit mine spoil heaps in arid and semi-arid regions. Background Technology

[0002] Open-pit mine spoil heaps are centralized sites for the discharge of mining waste, primarily storing waste from surface stripping or underground mining. In arid and semi-arid open-pit mine spoil heaps, evaporation rates are 5-10 times higher than rainfall. Furthermore, water and wind erosion lead to soil erosion, significantly increasing the maintenance costs of ecological restoration and causing vegetation degradation. Therefore, water scarcity in arid and semi-arid open-pit mine spoil heaps is a major factor limiting ecological restoration and sustainable development. Under the dual-carbon development goals, open-pit coal mines are vigorously developing new energy sources, constructing photovoltaic power stations on spoil heaps to achieve "photovoltaic power generation on the roof, ecological restoration underneath." Therefore, utilizing the electricity and wind power generated by the spoil heaps themselves to condense, collect, and utilize atmospheric water vapor can alleviate water scarcity in arid areas and reduce spoil heap maintenance costs.

[0028] The present invention will now be described in further detail in conjunction with the full text.

[0029] Combined with appendix Figures 1-6 A zero-carbon atmospheric condensate collection device for open-pit mine spoil heaps in arid and semi-arid regions includes a shell, a water collection hopper 12 installed under the shell, and an air intake fan 6 installed inside the shell.

[0030] The intake fan 6 is connected to one or a combination of an intake device and a power supply device for driving the intake fan 6 to rotate.

[0031] A condensation device for generating atmospheric condensate is installed inside the housing and below the intake fan 6.

[0032] The rotating shaft of the intake fan 6 is connected to a collection device for collecting atmospheric condensate generated by the condensation device.

[0033] The air intake device includes an air intake shroud 4 and a rotating shaft 2 connected to the housing. An air intake hole 5 is provided on the air intake shroud 4 and the air intake hole 5 communicates with the housing. The rotating shaft 2 is connected to an air intake fan 6 and extends into the housing. An air intake bracket 1 is installed on the outside of the rotating shaft 2 and on the air intake shroud 4. A rotating blade 3 is installed on the outside of the air intake bracket 1.

[0034] The intake bracket 1 can be a circular frame on both the top and bottom. The inside of the circular frame is reinforced by intersecting diagonals to increase stability.

[0035] The rotating shaft 2 is located vertically at the intersection of the diagonals inside the circular frame and runs through the entire air intake device and condenser device. The rotating blades 3 on the side are connected to the outer side of the circular frame above and below the air intake bracket 1. The air intake shroud 4 is located below the entire air intake bracket 1. The air intake fan 6 is located below the air intake shroud 4, and the air intake fan 6 is connected to the air intake bracket 1 by the same rotating shaft 2.

[0036] The rotating shaft 2 is connected to the air intake shroud 4 via a bearing.

[0037] The condensing device includes a condensing ring plate disposed inside the housing and located below the intake fan 6. The condensing ring plate is a coaxial set of multiple sets. The outer side of the condensing ring plate is coated with a radiative cooling material 10 and a hydrophobic material 9 in sequence. Then, an auxiliary ring plate with a hollowed-out side is used to fit the outer side of the condensing ring plate, and a hydrophilic material 8 is coated on the auxiliary ring plate.

[0038] In specific implementations of this invention, the radiative cooling material 10 can be a polymer, such as polyethylene or polydimethylsiloxane, with a porous structure that effectively scatters sunlight. The hydrophobic material 9 can be categorized into natural materials, organic synthetic materials, inorganic materials, composite materials, as well as biomimetic and nanostructured materials. Examples include natural materials like wax and lotus leaves, organic synthetic materials such as polytetrafluoroethylene (PTFE) and polydimethylsiloxane (PDMS), inorganic materials such as silica coatings, composite materials that may include polymers with added nanoparticles, and biomimetic materials such as micro / nano structures mimicking lotus leaves.

[0039] Hydrophilic materials typically refer to materials with a surface contact angle of less than 90 degrees, which readily interact with or are wetted by water. Common examples include metal oxides, certain polymers, and natural materials. Examples include titanium dioxide (TiO2), silicon dioxide (SiO2), polyethylene glycol (PEG), polyvinyl alcohol (PVA), and cellulose.

[0040] In this invention, the hydrophilic material 8, the hydrophobic material 9, and the radiative cooling material 10 can be used as a coating. The outer side of the condensing ring plate is sequentially coated with the radiative cooling material 10 and the hydrophobic material 9 to form a radiative cooling material layer and a hydrophobic material layer. Then, an auxiliary ring plate with a hollowed-out side is used to fit over the outer side of the condensing ring plate, and the hydrophilic material 8 is coated on the auxiliary ring plate to form a hydrophilic material layer.

[0041] The collection device includes a brush rotating bracket 11 connected to the rotating shaft 2. Multiple sets of electrostatic brushes 7 are installed on the brush rotating bracket 11, and the electrostatic brushes 7 are located inside the condensation annular plate.

[0042] The electrostatic brushes 7 are symmetrically distributed on both sides of the brush rotating bracket 11, sharing the same rotating shaft 2 with the air intake device and located inside the condensation ring plate. The water collection hopper 12 is located directly below the entire device and is used to collect atmospheric condensate passing through the device. The water collection hopper 12 is supported by four legs 13.

[0043] The lower end of the water collection hopper 12 is equipped with a support leg 13.

[0044] In specific implementation of this utility model, such as Figure 2 As shown, during use, the device is placed in the phytoremediation field of the mine spoil heap. The four legs 13 of the device are fixed to the ground. Utilizing the energy converted from photovoltaic power generation and wind power in the spoil heap, the device uses turbine-type rotating blades 3 and an intake fan 6 to condense gaseous water in the atmosphere into liquid water through the radiative cooling material 10. The condensed water moves away from the hydrophobic material 9 and collects at the end of the hydrophilic material 8. The condensed water is collected from the end of the hydrophilic material 8 to the water collection hopper 12 by the static electricity generated by the photovoltaic power generation in the spoil heap. The device fully utilizes the water vapor in the atmosphere to condense into liquid water without human intervention, thus reducing the maintenance cost of the spoil heap.

[0045] Specifically, this device is connected in sequence to a power supply device, an air intake device, a condensation device, and a collection device.

[0046] Power supply device: The power supply device includes a photovoltaic power generation panel 14 and a matching battery 16 connected through a photovoltaic panel output line 15, and outputs to the intake fan 6 through a DC load line 17. It adopts a monocrystalline silicon photovoltaic power generation panel 14, which is connected to the matching battery through a photovoltaic panel output line 15. When there is sufficient sunlight, the solar energy is stored in the battery 16, and a built-in controller is provided for overvoltage protection, overcurrent protection, and automatic shutdown when fully charged. The electrical energy is output through the DC load line 17.

[0047] Specifically, the photovoltaic power generation panel 14, DC load conductor 17 and battery 16 in the power supply device are all existing technologies and will not be described in detail here. Furthermore, an inverter for power conversion and other equipment for power exchange are also installed between the photovoltaic power generation panel 14 and the battery 16. The power supply device used is an existing technology.

[0048] Air intake device: When the spoil heap reaches a certain wind speed, the natural wind of the spoil heap enters the rotating blade 3 tangentially, driving the rotating blade 3 and the air intake fan 6 to rotate; when the wind speed of the spoil heap is lower than a certain wind speed, the electrical energy stored in the battery of the photovoltaic power generation panel is activated, directly driving the air intake fan 6 to blow the condenser ring plate of the condenser into the atmosphere.

[0049] Condensation device: The radiative cooling material 10 reduces the temperature of the outer surface of the condensing ring plate. The gaseous water entering through the air intake device condenses on the outer side of the condensing ring plate coated with the radiative cooling material 10. The condensed liquid water forms a water film on the outer side of the ring plate, and under the combined action of the hydrophobic material 9 and the hydrophilic material 8, it gathers more at the end of the hydrophilic material 8. The multi-layer condensing ring plates are stacked and arranged in the outermost ring protection plate to maximize the use of the condensation space.

[0050] Collection device: The electrostatic brush 7, which rotates on the same shaft 2 as the intake fan 6, continuously rotates and rubs the inner side of the condensation ring plate. The charged brush will attract the liquid water at the end of the hydrophilic material 8 and move along the brush trajectory. During the movement, the droplets gather into streams and flow down. The atmospheric condensate is collected into the water collection hopper 12 and can be used for plant irrigation.

[0051] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
