With the development of industries and advances in technology, pollutants are emitted and the air is seriously polluted. Discharged pollutants are transported and diffused in the air. Among them, polluting fine dust suspended in the air is not filtered through the nose or bronchial tubes, but penetrates deep into the respiratory tract, causing respiratory diseases such as asthma, bronchitis, allergic rhinitis, and lung disease, or It causes eye diseases such as conjunctivitis and dry eye syndrome. In addition, allergic dermatitis may occur when fine dust contains harmful ingredients to the skin.

Since such fine dust is as fine as 1mm to 01㎛ or less, it can be moved even by the flow of air.

Of course, in the past, various devices for removing such fine dust have been developed and sold on the market, but there is a problem in that the manufacturing cost is increased due to the complicated structure, and external air passing through the air inlet formed in front of the inlet is introduced again. There is a high possibility that the dust collection efficiency of fine dust may be lowered due to the phenomenon of backflow from the front to the outside.

1 is an overall configuration diagram of a fine dust dust collecting device according to an embodiment of the present invention.

As shown in FIG. 1 , the fine dust dust collecting device 90 according to the embodiment of the present invention includes cyclone

dust collecting units

100 and 110 , fine

dust collecting units

120 , 130 , 161 , 163 , and power distributor 140 . And it includes a part or all of the solar module unit 150, and may further include a main body that constitutes these components therein, that is, an outer case.

Here, the cyclone

dust collecting units

100 and 110 further include a suction fan 120 or a fine dust suction pipe 130 , and the fine

dust collecting units

161 and 163 can refer to only the conductor parts of the positive and negative electrodes, so such a distinction It is not particularly limited, and “including some or all” means that some components such as the power distributor 140 or the solar module unit 150 are omitted so that the fine dust collector 90 is configured, or the power distributor Some components such as 140 mean that they can be configured by being integrated with other components such as the solar module unit 150, and it will be described as including all of them to help a sufficient understanding of the invention.

The

cyclone dust collectors

100 and 110 collect fine dust in one place so that the replacement is made. The cyclone

dust collecting units

100 and 110 may be provided inside the main body. Of course, a driving unit for driving the fine dust collecting device 90 may be further configured in the main body. For example, the driving unit for driving the

cyclone dust collectors

100 and 110 may include a processor such as a CPU and an MPU and peripheral circuits thereof formed on a PCB substrate, and a control unit such as a processor controls the power distributor 140 . Thus, it is possible to control the solar power supplied to the

conductor parts

161 and 163 . Of course, since a control unit such as a processor is configured in the power distributor 140 and it is also possible to control the cyclone dust collector 110 in the power distributor 140, the embodiment of the present invention will not be particularly limited to any one configuration. In addition, the embodiment of the present invention is not particularly limited to solar power, but by using eco-friendly energy for the dust collector 90, it is eco-friendly, and can be installed anywhere the sun shines without a separate power supply facility, and is semi-permanent. can be used

The

cyclone dust collectors

100 and 110 are provided with a cyclone dust collector 110 performing a main operation, and a replacement dust collector 100 for collecting fine dust on one side of the cyclone dust collector 110 . The cyclone dust collector 110 may generate a cyclone-type wind by driving the suction fan 120 , and generate a suction force to the fine dust suction pipe 130 . And, the cyclone dust collector 110 collects the fine dust sucked through the fine dust suction pipe 130 in the replacement dust collector 100 . That is, the cyclone dust collector 110 separates the particles in the airflow by using the centrifugal force generated on the particles rotating with the gas. The cyclone dust collector 110 generates suction force to the fine dust suction pipe 130 through the suction fan 120 , then blocks the path of the suction fan 120 and opens the path of the replacement dust collector 100 to move fine dust can do it The cyclone dust collector 110 generates a rotating suction force as can be seen from its name. That is, fine dust is moved from the cyclone dust collector 110 to the replacement dust collector 100 by the cyclone action of the cyclone air stream continuously sucked through the cyclone fan. Since this moving process can be made in various ways, the embodiment of the present invention will not be limited to any one form.

The replacement dust collector 100 is provided on one side of the cyclone dust collector 110 and is coupled to facilitate replacement. The replacement dust collector 100 may include a backflow prevention part for preventing the backflow of fine dust in the path of the fine dust from the cyclone dust collector 110 , and the backflow prevention part may be formed of a plastic or rubber film. That is, the backflow prevention part may be formed such that the passage is opened only in the direction of the replacement dust collector 100 from the fine dust suction pipe 130 .

In addition, the fine

dust collecting units

120 , 130 , 161 , and 163 may include a suction fan 120 , a fine dust suction pipe 130 , and conductive parts (or collecting units) 161 and 163 . The suction fan 120 generates suction force to the cyclone dust collector 110 and the fine dust suction pipe 130 by a driving unit or a driving unit configured in the power distributor 140 . The suction fan 120 is provided with a cyclone fan, and by driving it, a vortex can be generated in the cyclone dust collector 110 by the cyclone airflow. The fine dust suction pipe 130 sucks fine dust collected by the non-uniform electric field generated between the

conductor parts

161 and 163 , that is, between the positive conductor part 161 and the negative conductor part 163 . Then, the inhaled fine dust is provided to the cyclone dust collector 110 and rotates, and is collected by the replacement dust collector 100 by the cyclone principle. As shown in FIG. 1 , the fine dust suction pipe 130 is positioned on a side where a strong electric field is formed by maintaining a close distance between the anode conductor part 161 and the cathode conductor part 163 . In other words, since the fine dust on the side with the weak electric field moves gradually toward the side with the strong electric field, the fine dust suction tube 130 is disposed on the side with the strong electric field to facilitate the suction of fine dust, and more fine dust can be inhaled. . This is because fine dust collects on the side where the electric field is strong.

The

conductive parts

161 and 163 of the fine

dust collecting units

120 , 130 , 161 and 163 play a key role for collecting fine dust. For this purpose, it may include an anode conductor part 161 and a cathode conductor part 163 . The

conductor parts

161 and 163 may be formed in various shapes, such as the shape of an electrode plate. However, the anode conductor part 161 and the cathode conductor part 163 are formed in asymmetrical state to generate a non-uniform electric field when they are charged with each other. In order to form an asymmetric state, the asymmetry may be formed in various forms, such as different lengths or different areas to be charged. For example, when forming the electrode plates of the anode and the cathode, respectively, the two electrode plates facing each other may be disposed in a manner that the gap decreases or increases from one side to the other side. That is, the gaps facing each other are formed differently. Through this, the fine

dust collecting units

120, 130, 161, and 163 are positively and negatively charged to trap the fine dust and move it to a dust collector (eg, a cyclone dust collector).

Looking more closely, fine dust that has a negative effect on the human body refers to dust that is so small that it is invisible to the naked eye floating in the atmosphere. It consists of metal compounds, etc. An effective method of collecting such fine dust is to use static electricity. Of course, since it is possible to collect and sterilize viruses using static electricity, the embodiment of the present invention will not specifically limit the collection of fine dust.

In an embodiment of the present invention, fine dust can be collected by charging two separated conductors with an anode and a cathode using solar energy that can be obtained anywhere to form an electric field between both conductors. Dust is more effectively captured. The two conductors charged with the positive and negative poles are configured to bend asymmetrically to each other, so that the strength of the electric field generated is different. Of course, since the strength of the electric field may vary depending on the area in which the electrode is formed, and the electric field may vary depending on the strength of the applied voltage, it may be formed by taking this into consideration comprehensively.

Therefore, in the embodiment of the present invention, if the dielectrophoretic principle can be used, the electrodes may be formed in various shapes, not in the arrangement of the electrodes, in order to maximize the dust collecting effect. For example, even if the distance over the entire area of the two electrode plates, that is, the positive and negative plates, is maintained the same, by forming more electrodes on one side or forming the electrodes so that the amount of electrodes is disposed from one side to the other side, it is difficult to bend. Even if the two electrode plates are not arranged, the strength of the electrode can be increased or decreased from one side to the other. Alternatively, the implementation according to the embodiment of the present invention may be possible by using different materials for the electrode. Furthermore, when a DC voltage is applied to the electrode, the strength of the electric field may be adjusted by dividing the regions and varying or adjusting the strength of the voltage. For example, assuming that the same interval is maintained, a large voltage is applied to one side by dividing the region, and a small voltage is applied to the other side. Alternatively, a voltage is applied to one side to collect fine dust, and then a voltage in a direction to be moved is applied while blocking the voltage in the corresponding area. In this way, the voltage is applied while sequentially moving from the far side to the near side to the fine dust suction pipe 130 . As such, it is possible to realize the dielectrophoretic principle or to adjust the strength of the electric field even through the driving of the control unit. This may be considered together in consideration of the mechanical aspect of the dust collector 90 , and may be utilized in consideration of the manufacturing cost, etc. comprehensively.

According to the principle of dielectrophoresis, in which particles move toward a higher strength in a non-uniform electric field, the collected fine dust moves to the center of each conductor and in the direction of dust intake. The collected fine dust is sucked by the cyclone dust collector 110 and accumulated in a separate dust collector 100 , and the dust collector 100 is periodically emptied.

The power distributor 140 stores power of the solar module unit 150 and distributes the stored power to the cyclone dust collector 110, the suction fan 120, and the

conductor units

161 and 163, respectively. have. As mentioned above, the power distributor 140 may include a main driving unit including a control unit such as a CPU. Of course, this is based on the assumption that the main driving unit is not configured in the cyclone dust collector 110 . Of course, it can also be configured to perform master and slave operations, including the main CPU and sub CPU, respectively. The power distributor 140 generates and distributes DC power together with the solar module unit 150 . The power divider 140 may include a DC-DC converter that drops or pumps a voltage. The photovoltaic module unit 150 includes photovoltaic cells, receives sunlight, converts light energy into electric energy, and provides it to the power distributor 140 .

Accordingly, the power distributor 140 may store the power provided by the solar module unit 150 including the storage battery. The generated DC power charges the two electrodes provided to the

conductive parts

161 and 163 constituting the fine

dust collecting units

120, 130, 161 and 163 through the power distributor 140 as positive and negative electrodes, and the cyclone dust collector 110 ) operates the suction fan 120 .

The above components described so far may be configured to be accommodated inside the main body, that is, the case (or structure, frame) and supported by a specific frame in the process. In particular, the photovoltaic module unit 150 may be provided at an angle on the upper side of the main body to receive sunlight. When installed in a specific device, movement may be automatically generated in the direction the sun shines. To this end, the direction can be controlled by measuring the amount of sunlight using an optical sensor or the like. Of course, you can also adjust the angle through this. In addition, the cathode and anode

conductive parts

161 and 163 constituting the fine

dust collecting parts

120, 130, 161, 163 may be provided in various shapes on one side of the main body, in this case, the anode part as shown in FIG. It is preferable to arrange the two electrodes of the cathode and asymmetrically curved portions. By configuring in this way, it can be used together with an air purifier in the house, or it can be manufactured in a small size and provided inside the vehicle. Of course, it is possible to apply it to industrial sites such as a production line in a factory, and it is possible to install it as a large structure on the roof of a building.

2 is a view for explaining the principle of formation of an electric field and adsorption and charging of dust, FIG. 3 is a view for explaining the movement of dust according to the difference in electric field, and FIG. A view showing the appearance, and FIG. 5 is a view for explaining the resorption in the middle connection pipe of the cyclone dust collector.

Referring to FIGS. 2 to 5 together with FIG. 1 , as shown in FIG. 2 , in the anode conductor part 161 and the cathode conductor part 163 of FIG. It forms and attracts fine dust floating in the air. Ionic fine dust is adsorbed by electrodes of opposite polarity, and neutral fine dust is charged in the opposite direction of the electric field.

In addition, as can be seen in FIG. 3 , the two electrodes (or electrode plates) are asymmetrically curved to form a non-uniform electric field, so that the fine dust increases the strength of the electric field according to the dielectrophoresis principle. It moves by receiving a force in the direction of the center of the large electrode and the fine dust suction pipe 130 of the cyclone dust collector 110 . Dielectrophoresis is a technology that forms a non-uniform electric field at the periphery of an electrode to attract or repel particles around the electric field to the electrode. Therefore, dielectrophoresis has a principle in which ionized particles and charged particles placed in a non-uniform electric field (or electric field) receive a force and move in a direction with a strong electric field. Accordingly, as shown in FIG. 4 , the moved and collected dust is accumulated in the dust collector 100 by the cyclone dust collector 110 .

As shown in (a) of FIG. 5 , fine dust of an ionic component flowing out by the rising internal vortex without falling into the dust collecting bin 100 is adsorbed and filtered by the intermediate connection pipe charged with the positive and negative electrodes. The fine dust of the ionic component adsorbed in this way decreases solar energy in the evening as shown in FIG.

For convenience of explanation, referring to FIG. 6 together with FIG. 1 , the fine dust dust collector 90 according to an embodiment of the present invention forms a non-uniform electric field between the two electrodes of the positive and negative electrodes to collect fine dust floating in the air. do (S600).

Here, the non-uniform electric field can be formed by arranging the two electrodes, the anode and the cathode, by asymmetrically bending them. At this time, according to the dielectrophoretic principle, the fine dust receives a force and moves toward the center of the electrode having a large electric field strength and the fine dust suction pipe 130 of the cyclone dust collector 110 .

In addition, the fine dust collector 90 moves the fine dust collected above to the replacement dust collector 100 by the rotational suction force of the cyclone dust collector 110 (S610).

Here, fine dust of ionic components flowing by the rising internal vortex without falling into the replacement dust collector 100 is adsorbed and filtered by the intermediate connecting pipe charged with the anode and the cathode. As mentioned above, the fine dust of the ionic component adsorbed in this way decreases solar energy in the evening and when the conductor is neutralized, it falls down by gravity and is accumulated in the dust collector 100 . Thereafter, the dust collector 100 may be replaced.

In addition to the above, the fine dust dust collecting device 90 of FIG. 6 may perform various operations, and since other detailed information has been sufficiently described above, it will be replaced with the contents.

On the other hand, even though it has been described that all components constituting the embodiment of the present invention are combined or operated in combination, the present invention is not necessarily limited to this embodiment. That is, within the scope of the object of the present invention, all the components may operate by selectively combining one or more. In addition, all of the components may be implemented as one independent hardware, but a part or all of each component is selectively combined to perform some or all of the combined functions in one or a plurality of hardware program modules It may be implemented as a computer program having Codes and code segments constituting the computer program can be easily inferred by those skilled in the art of the present invention. Such a computer program is stored in a computer-readable non-transitory computer readable media, read and executed by the computer, thereby implementing an embodiment of the present invention.

Here, the non-transitory readable recording medium refers to a medium that stores data semi-permanently and can be read by a device, not a medium that stores data for a short moment, such as a register, cache, memory, etc. . Specifically, the above-described programs may be provided by being stored in a non-transitory readable recording medium such as a CD, DVD, hard disk, Blu-ray disk, USB, memory card, ROM, and the like.

In the above, preferred embodiments of the present invention have been illustrated and described, but the present invention is not limited to the specific embodiments described above, and it is common in the technical field to which the present invention pertains without departing from the gist of the present invention as claimed in the claims. Various modifications may be made by those having the knowledge of, of course, and these modifications should not be individually understood from the technical spirit or perspective of the present invention.
