Description

Technical Field

[0001] This invention belongs to the field of wind power generation and smog control technology, and particularly relates to an outdoor self-circulating micro-wind power generation and smog removal system. Background Technology

[0002] CN104107592B discloses a "high-flow-rate, concentrated air purification system for haze removal," comprising a tower and a concentrated air hood. The tower contains a primary filtration layer and a secondary adsorption layer in its central section. A haze air inlet is located on the side wall of the tower below the filtration layer, and a clean air outlet is located at the top of the tower, connected to the central section of the concentrated air hood. A water storage chamber is located at the bottom of the tower, housing a submersible pump. The nozzle connected to the submersible pump is positioned between the primary filtration layer and the secondary adsorption layer. Haze-laden air enters the tower through the haze air inlet and is purified by the filtration layers. The concentrated air hood increases the airflow velocity, and the filtered clean air is extracted from the tower using a self-priming method, allowing operation even in light winds and increasing the daily air processing capacity. The haze-laden air, after passing through two stages of filtration and water filtration, exhibits significant haze purification effects. Power is supplied to the submersible pump and axial flow exhaust fan by a wind turbine and solar panels, achieving self-powered operation. Because the head of the wind collector also draws in unfiltered air, the final exhaust from the tail of the wind collector is a mixture of gases, including a small amount of unfiltered air. Moreover, the smog air is only filtered through two stages of filtration and water filtration, so the smog removal efficiency is not high. Summary of the Invention

The power generation chamber 4 includes a cylinder 34, which is a straight cylindrical structure made of transparent material. Four fan-blade generators 13 are installed inside the cylinder 34. The fan-blade generators 13 are staggered to maximize the wind power generation effect.

[0039] like Figure 3 , 10As shown, the smog removal module unit includes a filter chamber 5, the air inlet of which is connected to the air outlet of the cylinder 34 of the power generation chamber 4; the filter chamber 5 includes a first filter screen 14 disposed at the air inlet, the first filter screen 14 being circular in shape and having a mesh size of 30; a second filter screen 25 and a third filter screen 17 are respectively disposed inside the filter chamber 5 and at the air outlet, the second filter screen 25 being square in shape, the second filter screen 25 having a mesh size of 1600 mesh, and the third filter screen 17 having a mesh size of 6000 mesh; a fixed surface is provided on the bottom inside the filter chamber 5. The device includes a storage battery 16 and a voltage regulator 15. The power input terminal of the storage battery 16 is connected to the power output terminal of the fan-shaped generator 13, and the power output terminal of the storage battery 16 is connected to the power input terminal of the voltage regulator 15.

[0041] like Figure 4 As shown, the artificial magnetic field generating device 7 includes an artificial magnetic field box 32, the air inlet of which is connected to the air outlet of the negative ion field box 31; the interior of the artificial magnetic field box 32 is provided with a curved back plate 37 parallel to the direction of the airflow of the haze-laden breeze, and the two ends of the curved back plate 37 are fixedly connected to the N-plate 19 and the S-plate 20 respectively; the air outlet of the artificial magnetic field box 32 is provided with an artificial magnetic field sensor 29, and the power input terminal of the artificial magnetic field sensor 29 is connected to the power output terminal of the voltage regulator 15; the magnetic field is generated by the N-plate 19 and the S-plate 20. When the combination of haze particles and negative ions flows through the magnetic field with the wind, the magnetic force causes them to change their trajectory, thereby achieving a dust reduction effect.

[0042] like Figure 5As shown, the electrostatic field generating device 8 includes an electrostatic field box 33, the air inlet of which is connected to the air outlet of the artificial magnetic field box 32; six cathode plates 22 and five anode plates 21 are fixedly installed on the top surface inside the electrostatic field box 33, and the cathode plates 22 and anode plates 21 are parallel to the direction of the airflow carrying haze and arranged vertically; after the power is turned on, the cathode plates 21 and anode plates 22 generate 10 high-voltage electric fields. Under the action of the electric field force, the haze particles that are completely separated from the air move to the anode plates 22 and are deposited on the dust collection plate 26 under the action of gravity. Finally, the haze is removed by cleaning the dust collection plate 26; the filter chamber 5, the negative ion field box 31, the artificial magnetic field box 32 and the electrostatic field box 33 are all provided with openable switches for easy cleaning and maintenance.

[0043] like Figure 6 , 7 As shown in Figure 10, the monitoring room 9 includes a monitoring enclosure 40, the air inlet of which is connected to the air outlet of the electrostatic field enclosure 33; after the haze-laden breeze is filtered and cleaned through multiple layers, the clean air is discharged from the air outlet of the monitoring enclosure 40; a monitoring room sensor 11 is installed at the air inlet of the monitoring enclosure 40, and the power input terminal of the monitoring room sensor 11 is connected to the power output terminal of the voltage regulator 15; all pollution concentration sensors are product model M701, which detect the haze concentration in the breeze; a main control system 23 is installed inside the monitoring enclosure 40, and the power input terminal of the main control system 23 is connected to the power output terminal of the voltage regulator 15; the filter chamber sensor 27, negative The ion field sensor 28, the artificial magnetic field sensor 29, and the monitoring room sensor 11 are all pollutant concentration sensors. The electrical signal input terminal of the main control system 23 is connected to the electrical signal output terminal of each pollutant concentration sensor, and the electrical signal output terminal of the main control system 23 is connected to the electrical signal input terminal of the digital display module screen 10.

The main control system 23 can also transmit the monitored haze concentration data to the remote monitoring system 12 through the 2.4G wireless transmission module 24 to realize remote and on-site dual monitoring. The main control system 23 is an STM32F103C8T6 microcontroller.

[0044] This indicates that the output power P of the fan-blade generator 13 is related to the air density ρ, the fan blade area A3 of the fan-blade generator 13, the cube of the wind speed, and the efficiency η of the fan-blade generator 13. The relationship between the fan blade area A3 of the fan-blade generator 13, the air velocity V1 at the inlet of the micro-wind capture device 1, and the air velocity V2 at the outlet of the power generation chamber 4, and the output power P of the wind power generation is shown in the following formula:

[0045]

[0046] Wherein, V1 is the air velocity at the inlet of the wind-catching device 1, in meters per second (m / s); V2 is the air velocity at the outlet of the power generation chamber 4, in meters per second (m / s); and A2 is the area of ​​the air inlet of the power generation chamber 4, in square meters (m²). 2 A1 represents the air inlet area of ​​the micro-wind capture device 1, in square meters (m²). 2 );

[0047] The output power P of the fan-blade generator 13 is shown in the following formula:

[0048]

[0049] Where P is the output power of the fan-blade generator 13, in watts (W); ρ is the air density, in kilograms per cubic meter (kg / m³). 3 A3 represents the blade area of ​​the fan-bladed generator 13, in square meters (m²). 2 V2 is the air velocity at the outlet of generator chamber 4, in meters per second (m / s); η is the efficiency of fan-blade generator 13, usually between 0.3 and 0.5, without unit.

[0050] The area of ​​the fan blade generator 13, the air inlet of the wind capture device 1, and the air outlet of the power generation chamber 4 are appropriately designed according to the local geographical location, wind speed, and haze conditions, so as to ensure the power supply for the normal operation of each haze removal module unit, pollutant concentration sensor, and main control system.

[0051] The working principle of this invention is:

[0052] During operation, after the 360° omnidirectional wind-catching device 1 collects air, the haze-laden air enters the wind-accelerating device 2. Utilizing the Venturi effect, the wind speed inside the wind-accelerating device 2 increases due to the gradually decreasing cross-section of the airflow, creating a pressure difference between the inlet and outlet of the device. This results in adsorption, meaning the haze-laden air rapidly increases in speed as it is continuously adsorbed. The wind-guiding device 3 then accelerates the airflow to a second-order speed. A large volume of high-speed haze-laden air enters the power generation chamber, driving the fan-blade generator 13 to rotate, converting wind energy into electrical energy to power the subsequent haze removal module, pollutant concentration sensor, and main control system. Next, the haze-laden air passes through the first filter 14 at the inlet of the filter chamber 5 for preliminary filtration, and continues through the second filter 25 and the third filter 17. The gaps in these filters allow for the absorption of haze-laden air. The airflow gradually decreases in direction, filtering out large haze particles before entering the negative ion field generating device 6. Negative ions are generated by the cluster negative ion generator 1, combining with tiny haze particles to cause them to clump together. When passing through the artificial magnetic field 7, the tiny haze particles, having absorbed negative ions, are further filtered and settled under the influence of the magnetic field. Finally, the haze-laden airflow continues into the electrostatic field generating device 8. Under the influence of the high-voltage electric field, the cathode plate 21 undergoes corona discharge, filling the electrostatic field with negative ions. These negative ions combine with the tiny haze particles and are adsorbed onto the anode plate 22. Under gravity, the tiny haze particles settle onto the dust collection plate 26 and are ultimately discharged into the atmosphere through the control room 9. Throughout the haze removal process, the haze concentration in the airflow is detected by a pollutant concentration sensor, and the haze concentration data is displayed on the digital display module screen 10 or the remote monitoring system 12, achieving both remote and on-site monitoring.

[0053] The above are preferred embodiments of the present invention. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on the invention are within the scope of protection of the present invention.
