Description

1. Field of the Invention The present invention relates to a fanless dust collection device-integrated solar-powered soundproof wall, and more specifically, to a fanless dust collection device-integrated solar-powered soundproof wall which can improve the efficiency of fine dust collection and soundproofing using a fanless dust collection device, and at the same time convert solar energy into electrical energy to be used as a power source for the fanless dust collection device. 2. Discussion of Related Art As is known, a soundproof wall is a wall installed to prevent sound from leaking out or leaking in from one side to the other side. A representative example is a large soundproof wall installed along an edge of a road or railway. A soundproof wall is manufactured in consideration of a ‘sound reception point,’ which is the location that receives the most noise. During manufacture, factors, such as a sound absorption rate (how much sound the wall absorbs), a transmission loss (how much noise is reduced when passing through the wall), and an insertion loss (how much the decibel level is reduced after the wall is installed), are considered. Currently, in South Korea, soundproof walls are manufactured and installed according to standards set by the Ministry of Environment, which include not only functional aspects mentioned above, but also aesthetic and safety aspects. As the related art related to soundproof walls, ‘Information and Communication Technology (ICT) Convergence Fine Dust Reduction Soundproof Wall’ is disclosed in Korean Registered Patent No. 10-2305654, which was registered on September 17,2021. The ICT convergence fine dust reduction soundproof wall includes an sound absorption filter module which includes a guide part through which noise and hazardous air pollutants flow in, a filter reducing the noise and harmful substances flowing in from the guide part, and a sensor provided in the guide part and sensing the noise and hazardous air pollutants, a soundproof module which extends upward from the sound absorption filter module and guides the hazardous air pollutants rising upward while reflecting and refracting the noise, and an upper filter module which includes a guide wall which extends upward from the soundproof module, a guide member that is spaced apart from the guide wall to form a dust collection filter space between the guide wall and the guide member and guides the rising hazardous air pollutants, and an upper filter module provided between the guide wall and the guide member and including an upper filter for filtering the hazardous air pollutants. Here, the guide member is curved so that the dust collection filter space has an area that narrows toward the upper filter, thereby increasing the inflow speed of the hazardous air pollutants flowing into the dust collection filter space. To reduce both noise and air pollution generated from the road or railway, a dust collection device has been installed in the soundproof wall. As the related art related to a dust collection device, Korean Registered Patent No. 10-2284828, titled ‘Dust Collection Device,’ is disclosed (Registration Date: July 27, 2021). However, to operate the dust collection device installed in the soundproof wall, additional wiring work, such as pulling wires for installation or connecting various electrical devices with wires, should be performed. Moreover, when the dust collection device is installed in the soundproof wall, one surface of the dust collection device protrudes from an outer surface of the soundproof wall, which not only fails to present a clean and aesthetic appearance, but also causes the center of gravity of the soundproof wall to be biased, leading to a problem of structural stability. In particular, the dust collection device needs regular maintenance to remove dust collected on collecting electrodes. However, considering the locations where the soundproof walls are installed, such as roads or railways, realistically, maintaining the dust collection device and ensuring the safety of workers are very difficult. [Patent Documents] Korean Registered Patent No. 10-2305654 (Registration Date: September 17, 2021) Korean Registered Patent No. 10-2284828 (Registration Date: July 27, 2021) SUMMARY OF THE INVENTION The present invention is directed to providing a fanless dust collection deviceintegrated solar-powered soundproof wall which can improve the efficiency of fine dust collection and soundproofing using a fanless dust collection device and can conveniently and safely maintain the fanless dust collection device by washing dust collecting electrodes with rainwater.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings to ensure a thorough understanding of the invention. The embodiments of the present invention may be modified into various forms, and the scope of the invention should not be interpreted as limited to the embodiments described in detail below. These embodiments are provided to more fully explain the invention to those skilled in the art. Accordingly, the shapes of the components depicted in the drawings may be exaggerated to emphasize a clearer explanation, and identical elements may be denoted by the same reference numerals in the drawings. Additionally, a detailed description of well-known functions and structures may be omitted if it is determined that such a description may unnecessarily obscure the gist of the present invention. A fanless dust collection device-integrated solar-powered soundproof wall according to an exemplary embodiment of the present invention includes vertical frames 200, a solar panel 400, a soundproof panel 600, a fanless dust collection device 100, a space frame 300, and a water supply channel 500. The vertical frames 200 form a main structure of an embodiment of the present invention. The vertical frames 200 are installed at predetermined intervals along edges of a road or railway. The vertical frame 200 may be made of vertical shaped steel beams with various cross-sectional shapes. The fanless dust collection device 100 is installed in a front center of the vertical frame 200, and sound insulation panels 210 absorbing and blocking noise may be installed on upper and lower portions of the front surface of the vertical frame 200 excluding a portion at which the fanless dust collection device 100 is installed. The sound insulation panels 210 along with the soundproof panel 600 doubly absorb and block noise generated from the road or railway to improve sound absorption performance. Space frames 300 are connected to the vertical frame 200 such that the solar panel 400 and the soundproof panel 600 are spaced apart from the front surface of the vertical frame 200. In this case, the space frame 300 supports the solar panel 400 and the soundproof panel 600 so that front surfaces of the solar panel 400 and the soundproof panel 600 are aligned Optionally, the space frame 300 may be implemented as a combination of a transom as a horizontal member, and a mullion as a vertical member. The solar panel 400 is installed at an upper portion between the two adjacent vertical frames 200 to convert solar energy into electrical energy. The solar panel 400 may further include a battery (not shown) which stores the converted electrical energy and supplies the electrical energy as a power source for the fanless dust collection device 100. Since the fanless dust collection device 100 may be operated by power supplied from the solar panel 400, there is no need for additional wiring work to connect wires from a utility pole or the like located outside the soundproof wall to the fanless dust collection device 100 to use electric power. The water supply channel 500 is formed between the solar panel 400 and the vertical frame 200 to guide rainwater to an inlet 111 of the fanless dust collection device 100. In short, rainwater is guided through the water supply channel 500 to the inlet 111 of the fanless dust collection device 100 and flows down to a dust collection part to be described below, so that the dust collected on the dust collecting electrodes can be washed. The soundproof panel 600 is installed at the lower part of the vertical frame 200 between the two adjacent vertical frames 200 to absorb the noise generated from the road or railway. The soundproof panel 600 may be formed in a flat shape with a porous soundabsorbing material which may absorb noise to reduce sound energy. A drainage channel 510 is formed between the soundproof panel 600 and the vertical frame 200 to drain the rainwater, which washes the dust collected in the fanless dust collection device 100, to the ground E. In short, rainwater is supplied through the inlet 111 into the fanless dust collection device 100, washes the dust collected on the dust collecting electrodes, and then is discharged to the outside of the fanless dust collection device 100 through an outlet 112, and flows through the drainage channel 510 to be drained to the ground E. In the present invention, the drainage channel 510 is not essential, and when the drainage channel 510 is not formed, rainwater discharged to the outside of the fanless dust collection device 100 through the outlet 112 may flow along a front surface of the soundproof panel 600 through a discharge channel 710 to be described below and may be drained to the ground E. The fanless dust collection device 100 functions to receive, purify, and discharge external air without the use of a powered device such as a blower unit. The fanless dust collection device 100 is installed on the vertical frame 200 between the soundproof panel 600 and the solar panel 400, purifies the external air entering through the inlet 111 on the upper portion of the vertical frame 200, and discharges the external air through the outlet 112 on the lower portion thereof. The fanless dust collection device 100 may include a main body 110, a sound absorption part 120, and a dust collection part 130. The main body 110 is installed in the front center of the vertical frame 200 and provides a frame for installing the sound absorption part 120 and the dust collection part 130. The main body 110 may include a front surface to which a front soundabsorbing panel 121 is fixed, lateral surfaces connected to both sides of the front sound-absorbing panel 121, and a rear surface connected to the lateral surfaces, and the top and bottom of the main body 110 may be open. The inlet 111 is formed in the open top of the main body 110 to allow external air to flow in, and the outlet 112 is formed in the open bottom of the main body 110 to discharge purified air from which dust included in the external air is removed by the dust collection part 130. The dust collection part 130 fixed to the lateral surfaces and the rear surface of the main body 110 is installed in the main body 110. An inner sound-absorbing panel 123 fixed to the inner rear surface of the main body 110 is installed under the dust collection pail 130. The outlet 112 of the main body 110 may have an open structure without a component such as a cover, and an air guide part (not shown) is further installed to facilitate the discharge of purified air. An inflow channel 700 may be formed between an upper end of the main body 110 and a lower end of the solar panel 400 to guide the inflow of external air to the inlet 111. The discharge channel 710 may be formed between the bottom of the main body 110 and the top of the soundproof panel 600 to guide the discharge of purified air discharged from the outlet 112. The sound absorption part 120 includes the front sound-absorbing panel 121 forming a front surface of the main body 110 and the inner sound-absorbing panel 123 fixed to the rear surface of the main body 110 to be positioned under the dust collection pail 130 in the main body 110 and prevents noise from spreading by reflecting and absorbing the noise. The front sound-absorbing panel 121 and the inner sound-absorbing panel 123 may be manufactured in a flat shape with a sound-absorbing material which absorbs noise. The front sound-absorbing panel 121 may include an inflow surface 121a which has a plurality of holes 122 through which purified air is discharged and a noninflow surface 121b which does not have the holes 122. The inner sound-absorbing panel 123 functions to absorb sound waves entering the main body 110 through the holes 122 of the front sound-absorbing panel 121 by a rear air layer in a resonance frequency range and then attenuate the sound waves by hitting the sound-absorbing material, thereby further enhancing the noise attenuation performance of the fanless dust collection device 100. The inner sound-absorbing panel 123 is formed with a hole-free flat structure with a thickness which does not obstruct the outlet 112 of the main body 110. In the present invention, the front sound-absorbing panel 121 and the inner sound-absorbing panel 123 which constitute the sound absorption part 120 may be manufactured of an aggregate-based sound-absorbing material having a noise reduction coefficient (NRC) of 0.7 or higher, non-combustibility suitable for semi-non-combustible standards, and freeze-thaw resistance with a compressive strength ratio of 70% or higher. The dust collection part 130 may be installed on one side of the non-inflow surface 121b of the front sound-absorbing panel 121. The dust collection part 130 purifies external air flowing into the inlet 111 of the main body 110 without power and discharges the purified air through the outlet 112 of the main body 110. The dust collection part 130 may include a housing 131, discharge plates 132, collecting electrodes 133, and non-collecting electrodes 134. The housing 131 provides a framework in which the discharge plates 132, the collecting electrodes 133, and the non-collecting electrodes 134 are installed. The discharge plates 132 are formed with metal plates to generate a corona discharge by applying a positive or negative voltage, thereby generating ions and functioning as an emitter. The discharge plates 132 arc formed as long strip-shaped plates. Isosceles triangular shaped discharge parts 132a, at which the negative or positive voltage applied to the discharge plate 132 is collected, are formed at regular intervals. Discharge pins 132b are formed at tip ends of the discharge parts 132a, positioned toward the collecting electrodes 133 and the non-collecting electrodes 134, at regular intervals and generate a corona discharge. The discharge plates 132 have water-repellent structures 132c formed at lower surfaces of the discharge plates 132 between the discharge parts 132a to minimize the tension with water drops during washing, thereby minimizing water accumulation on the discharge plates 132. The discharge plates 132 may be joined and installed to a first support 1311 by welding and the like. The discharge parts 132a and the discharge pins 132b may be integrally formed with the discharge plates 132 or separately manufactured and then joined to the discharge plates 132. The discharge plates 132 including the discharge parts 132a and the discharge pins 132b may be made of metal, such as stainless steel, tungsten, plated steel, or plated tungsten, with a predetermined thickness. The collecting electrodes 133 are installed to be spaced apart from the discharge pins 132b toward the outlet 112, include a plurality of first metal plates with a polarity opposite to that of the discharge pins 132b to induce ions generated at the discharge pins 132b, and generate an ion wind along with the discharge pins 132b. In this case, the collecting electrode 133 may act as a collector. The plurality of first metal plates constituting the collecting electrodes 133 are provided in parallel at regular intervals and alternately disposed at a first distance from the discharge pins 132b toward the outlet 112. The non-collecting electrodes 134 may include a plurality of second metal plates with the same polarity. The plurality of second metal plates constituting the non-collecting electrodes 134 may be provided in parallel with the plurality of first metal plates constituting the collecting electrodes 133 in an alternating manner, and may be disposed in parallel with the discharge pins 132b at a second distance greater than the first distance from the discharge pins 132b toward the outlet 112. The dust collection part 130 may remove dust included in the external air without power and without using a blower unit by applying a voltage to the discharge plates 132, the collecting electrodes 133, and the non-collecting electrodes 134. Specifically, when the discharge pins 132b generate ions, the generated ions are induced to the collecting electrodes 133 and generate an ion wind flowing toward the outlet 112. That is, the ions generated at the discharge pins 132b move to the collecting electrodes 133 formed of the first metal plates with the polarity opposite to that of the discharge pins 132b, and momentum is transferred to neutral air molecules due to collisions with the neutral air molecules, thereby generating an ion wind. The external air may be moved by the ion wind between the collecting electrodes 133 to the outlet 112 without power and without using a blower unit. In this case, fine dust particles included in the external air moved by the ion wind collide with the ions to cause a charging phenomenon of the particles, the charged particles also move and are attached to the first metal plates, which are the collecting electrodes 133. That is, the dust included in the external air collides with the ions generated at the discharge pins 132b and is charged with the same polarity as that of the discharge pins 132b. The charged dust is collected on the collecting electrodes 133 by an attractive force with the collecting electrodes 133 with the opposite polarity. In addition, the flow of the charged dust to the outlet 112 is prevented by a repulsive force with the non-collecting electrodes 134 with the same polarity, and the dust is collected on the collecting electrodes 133. Further, the discharge plates 132 are disposed above the collecting electrodes 133 and the non-collecting electrodes 134, which allows water drops formed on each component during washing to be removed by falling downward toward the outlet 112 due to gravity. The ion wind generated during the operation of the discharge plates 132, the collecting electrodes 133, and the non-collecting electrodes 134 allows a force, which removes water drops, to increase to minimize the water drops remaining on the discharge plates 132, the collecting electrodes 133, and the non-collecting electrodes 134, thereby increasing a dewatering effect and preventing the generation of sparks. Since the fanless dust collection device 100 described above, which is a dust collector without a blower unit, includes a sound absorption part 120 formed of a high strength sound-absorbing material and the like as one component, the durability of the device can be secured and air flow can be induced in various directions depending on the structure of the sound absorption part 120. An air layer in the main body 110 due to the dust collection part 130 being installed in the main body 110 provides an advantage of increased acoustic performance compared to a conventional soundproof wall, such as enhancing low-frequency noise reduction performance. The sound absorption part 120 prevents a high voltage applied to the dust collection part 130 from being transmitted to a user or affecting the outside. The operation of the exemplary embodiment of the present invention configured as described above will be described in detailed with reference to the accompanying drawings. Solid line arrows shown in FIG. 4 show the flow of air, and dashed line arrows show the flow of rainwater. First, the external air may flow into the inlet 111 of the fanless dust collection device 100 through the inflow channel 700 and the water supply channel 500. Next, the external air flowing into the fanless dust collection device 100 is purified by the dust collection part 130, then exits through the outlet 112, and is discharged to the outside of the soundproof wall through the discharge channel 710. Meanwhile, rainwater falling during rainfall is guided into the inlet 111 of the fanless dust collection device 100 through the water supply channel 500 and flows into the dust collection part 130. Then, the rainwater flowing into the dust collection part 130 of the fanless dust collection device 100 washes the dust collected on the collecting electrodes 133 and is drained to the ground E through the outlet 112. Therefore, according to the embodiment of the present invention, the fanless dust collection device 100 can not only improve the efficiency of fine dust collection and soundproofing, but also can be safely and conveniently maintained by automatically washing the collecting electrodes using rainwater. Also, according to the embodiment of the present invention, the fanless dust collection device 100 can prevent air pollution by purifying the polluted external air flowing into the inflow channel 700 and discharging the purified air through the discharge channel 710. According to the embodiment of the present invention, the sound insulation panel 210 is installed on the front surface of the vertical frame 200, excluding a part at which the fanless dust collection device 100 is installed, to absorb noise and prevent the noise from leaking through gaps of the inflow channel 700 and the discharge channel 710, thereby enhancing the sound absorption performance of the soundproof wall. In addition, according to the embodiment of the present invention, electrical energy converted in the solar panel 400 is stored and directly supplied as a power source for the fanless dust collection device 100, thus wiring work, such as pulling wires for installation or connecting various electrical devices with wires, is not needed. Meanwhile, FIG. 5 is a side cross-sectional view according to another embodiment of the present invention. Referring to FIG. 5, a porous member 800 is combined in the water supply channel 500 to collect a certain amount of rainwater and supply the rainwater at one time while reducing the inflow of external air. The porous member 800 is made of a porous material with numerous pores with a diameter of 3 to 5 mm to smoothly guide rainwater to be supplied and also provide a sound absorption function while reducing or blocking the inflow of external air and foreign materials. Optionally, the porous member 800 may be implemented in a form in which granules are put in a wire mesh casing to form pores with a diameter of 3 to 5 mm. Alternatively, the porous member 800 may be molded in a panel shape by foaming synthetic resin to form pores with a diameter of 3 to 5 mm. For example, it is more efficient to purify the external air flowing in from the ground level of a road or railway where many pollutants are present to enhance the dust collection efficiency of the fanless dust collection device 100. However, when the water supply channel 500 is open, more external air may flow into the fanless dust collection device 100 from the upper side of the soundproof wall than from the ground level of the road or railway. To prevent this, when the porous member 800 is combined to fill an open space of the water supply channel 500, since the cross-sectional area of the water supply channel 500 is reduced by numerous pores, the amount of external air flowing in through the water supply channel 500 decreases while the amount of external air flowing in through the inflow channel 700 increases. Therefore, the dust collection efficiency of the fanless dust collection device 100 can be improved. Also, the porous member 800 does not interfere with the supply of rainwater to the inlet 111 of the fanless dust collection device 100 due to pores with a diameter of 3 to 5 mm. Additionally, since the porous member 800 stores the rainwater in the pores and discharges a large amount of rainwater at one time when a certain amount of rainwater accumulates, the cleaning efficiency of the dust collected on the collecting electrodes 133 is maximized. Further, the porous member 800 provides a sound-absorbing function due to the pores and also functions as a filter to prevent foreign materials, such as leaves, from entering the inlet 111 of the fanless dust collection device 100. According to the present invention, the fanless dust collection device can enhance the efficiency of fine dust collection and soundproofing, can be conveniently and safely maintained by automatically washing the collecting electrodes with rainwater, can prevent air pollution by purifying the polluted external air flowing into an inflow channel in the fanless dust collection device and discharging the purified air through the outlet channel, and can improve the sound-absorbing performance of the soundproof wall by allowing the soundproof panel installed on the front surface of the vertical frame excluding a portion of the fanless dust collection device to absorb noise and block the noise from leaking through gaps of the inflow channel and the outlet channel. The above-described embodiments should be considered only as examples and not for purposes of limitation, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments may be made. Therefore, it should be understood that the present invention is not limited only to the forms mentioned in the detailed description. Accordingly, the technical scope of the present invention is determined by the technical idea of the appended claims, and various equivalents and modifications may include the technical idea of the present invention defined by the appended claims and all such modifications, equivalents, and substitutions that fall within the scope of the present invention.
