Description

Fine dust removal device {APPARATUS FOR COLLECTING FINE DUST}

The present invention relates to a device for removing fine dust in the atmosphere, and more particularly, by allowing the fine dust in the air to be trapped in the process of contacting the water film formed on the inclined plate for adsorption installed on the ground to collect fine dust in the atmosphere It relates to an outdoor fine dust removal device that can lower the concentration of.

It is a serious social concern that the amount of fine dust is rapidly increasing due to the rapid increase in industries that generate various types of exhaust gas, including vehicles. While some fine dust discharged to the atmosphere is carried in the wind by the air pressure difference on the surface, it is removed in the course of passing through the forest, or it is removed to some extent through natural removal ability, such as washing with rainwater and removing it to some extent. In accordance with the trend of industrialization, the amount of fine dust has already exceeded the natural removal ability described above, so the gradual increase in the concentration of fine dust in the atmosphere is inevitable.

Countries around the world have been controlling emissions of fine dust since the'Paris Climate Agreement in Paris' in 2016 to improve the pollution problem of the increasingly deteriorating air environment, but due to their industrial competitiveness, the standards are not strictly applied. As there are no people, the pollution of the air environment is becoming increasingly serious.

On the other hand, fine dust already discharged into the atmosphere floats up to several tens of kilometers above the surface and water surface through the circulation process of air such as wind and air convection caused by air pressure differences, and acts as a major cause of global warming. On the other hand, since it acts as a source of various respiratory diseases, it is no longer able to rely on the natural extinction of fine dust in the atmosphere.

As a countermeasure against the current fine particulate matter, it is known that an air cleaner is installed indoors to prevent the damage from the fine particulate matter. The air cleaner removes fine dust in the indoor air or lowers its concentration by allowing adsorption and removal of fine dust in the process of passing through a filter mounted inside the device using forced air inhalation or blowing using electricity. have.

However, there is no known device or facility for removing fine dust already present in the outdoor atmosphere, and it is open to remove fine dust floating in the air by installing an air cleaner installed indoors outdoors. It is in a practically impossible state due to the wide range of waiting spaces and economic problems due to the mass installation of devices.

Thus, at least the effective concentration of fine dust in the air can be reduced even if the concentration of fine dust in dense living and residential spaces, including areas with high concentrations of fine dust in the atmosphere or areas with frequent fog or smog containing fine dust. There is an urgent need for device development.

The present invention was devised in consideration of the conventional problems and practical necessities related to the above-mentioned atmospheric fine dust, and is installed in an area or a dense living and residential space where the concentration of atmospheric fine dust is relatively high, thereby providing separate power for air supply or ventilation. The purpose is to provide an atmospheric fine dust removal device that can remove fine dust at all times by using the convection phenomenon of air and the phenomenon of air movement (circulation) due to the adsorption characteristics of water and the air pressure difference without the need. I have it.

Another object of the present invention is to install a water guide between the pair of side frames fixed to the ground spaced apart from each other, and install a slant guide plate in multiple stages up and down while allowing water to flow down, and a water pedestal between each inclined guide plate. It is to provide an apparatus for removing atmospheric fine dust in such a way that the water film area of water continuously supplied is continuously maximized within a limited area so that fine dust in the air contacting the guide plate during movement is adsorbed into the water film on the guide plate.

Another object of the present invention is to ensure that the water film is formed on the entire surface of the inclined guide plate regardless of the direction or intensity of the wind, and allows the original state of the formed water film to remain intact even with strong lateral wind. And it is to provide an atmospheric fine dust removal device installed on the ground in a compact size so that the installation area and scale are minimized without dropping the urban aesthetic.

It is desirable to induce even distribution and flow.

In addition, the vertical guide ribs extending from the vertices where both inclined surfaces meet are formed integrally with the lower guide plates except for the uppermost inclined guide plate, thereby extending through the upper portion of the through hole formed in the center of the upper water pedestal. The water supplied to the inclined guide plate is prevented from being supplied to one side of the front or rear inclined surface or the lower surface of the inclined surface due to the influence of the wind, so that it is evenly distributed from the upper ends of both inclined surfaces and serves to drop. do.

The water that flows from the front guide plate to the water support through the half-divided through holes on both sides of the vertical ribs is formed so that the width of the through holes is larger than the cross-sectional thickness of the vertical ribs. With the plate, water flowing from the rear guide plate is supplied to the rear guide plate again.

Among the water pedestals, the bottom of the water pedestal maintains a closed state in which a separate long hole is not formed on the bottom surface, and water collected in the bottom of the water pedestal of this type is directed to the water tank through a pipe connected to the water tank. .

Then, the water collected in the water tank is supplied to the inclined guide plate along the water supply pipe leading upwards to the upper inclined guide plate. At this time, the discharge side of the water supply pipe is combined with a distribution pipe extending in parallel with the upper smooth surface of the uppermost inclined guide plate so that water can be uniformly supplied over the entire length of the upper end of the inclined guide plate.

The above technical object, configuration and effect of the present invention will be more clearly understood through the following detailed description with reference to the drawings of embodiments of the present invention.

First, FIG. 1 is a perspective view of a fine dust removing device according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of the device of FIG. 1.

As illustrated, the apparatus for removing fine dust according to an embodiment of the present invention is inclined guide plates 2a, 2b, 2c between a pair of side frames 1 vertically fixed to the ground at intervals from each other ) Is installed in three stages up and down, and a water pedestal (3a) that forms a water film on the surface of the inclined guide plates (2a, 2b, 2c) and supplies flowing water to the inclined guide plates at the bottom. , 3b, 3c), and the water flowing into the lowermost water support 3c is collected in the water tank 4 through the pipe 4a and the uppermost inclined guide plate 2a along the water supply pipe 5 ).

The material of the pair of side frames (1), the inclined guide plates (2a, 2b, 2c) and the water support (3a, 3b, 3c) is preferably composed of a high-strength, durable plastic or metal material. Depending on, it may be made of other materials.

Next, the inclined guide plates 2a, 2b, and 2c are bent at an angle of approximately 90° to form an elongated plate body having front and rear inclined surfaces, forming a front and rear downward inclined surface at an angle of approximately 45° relative to the vertical axis from the ground. It is preferable to be fixed on the furnace side frame (1). When the inclination angle θ of the inclined guide plate is too small to form an almost inclined angle, the water flowing down the inclined guide plate spreads evenly on the surface of the inclined surface, making it impossible to form a water film over the entire area. When the inclination angle is too large to be close to the horizontal, the reduction of the contact area between the guide plate and the atmosphere including fine dust is inevitable, and the efficiency of removing fine dust decreases.

Among the inclined guide plates fixed on the side frame 1 in multiple stages up and down, the upper inclined guide plate 2a is formed such that the upper vertex portion forms a smooth surface ps of a narrow width along the longitudinal direction. The water supplied from 5) is evenly distributed to the front and rear slopes of the slope guide 2a to flow down.

On the other hand, except for the uppermost inclined guide plate 2a, the lower inclined guide plates 2b and 2c are integrally formed with a vertical rib vr extending upward from a vertex where both inclined surfaces meet, thereby forming an upper water support 3a. , 3b) by being extended through the upper portion of the through hole (o) formed in the center, it is evenly dropped from the water support (3a, 3b) to the upper portion of the front and rear slopes where water is supplied to the inclined guide plates (2b, 2c) below it. As much as possible.

Next, the water pedestals 3a, 3b, and 3c have both ends of the bottom surface 3aa, 3ba, and 3ca bent upward, so that the upper ends of the bent portions 3ab, 3bb are inclined guide plates 2a, 2b, 2c. It is configured to be positioned slightly above the lower part, so that water flowing down the inclined guide plates 2a, 2b, 2c is collected into the water pedestals 3a, 3b, 3c without splashing out of the device.

At this time, the width of the water support (3a, 3b, 3c) is slightly smaller than the width of the side frame (1), the water film formed on the inclined guide plates (2a, 2b, 2c) due to the wind from the side is inclined It is preferable to prevent it from flying off the surface.

Among the water pedestals, the lowermost water pedestal 3c is a bottom face 3ca in which no separate through holes are formed in the bottom face, and is preferably formed to have a cross section that is downwardly downward toward the center. The water collected in 3c) is directed to the water tank 4 through a pipe 4a connected to the water tank 4.

The water collected in the water tank is moved along the water supply pipe 5 extending upwardly from the uppermost inclined guide plate 2a and discharged toward the inclined guide plate 2a. At this time, the discharge side of the water supply pipe (5) is coupled to the distribution pipe (5a) is formed extending in parallel with the upper smooth surface (ps) of the uppermost inclined guide plate (2a) is evenly distributed over the entire section of the inclined guide plate top It is configured to supply. Unexplained reference numeral 5ab is a water discharge hole finely drilled at equal intervals on the bottom surface of the distribution pipe 5a.

On the other hand, Figure 3 is a longitudinal cross-sectional view of the apparatus in accordance with the embodiment of Figure 1 installed on the ground, as shown, the water tank 4 is installed in a buried state under the ground. At this time, a filter (not shown) may be mounted inside the water tank 4 to filter out fine dust contained in the water flowing into the water tank. In addition, although not shown in the drawings, a pump is installed on the water tank and the water supply pipe path to continuously supply water through the water supply pipe 5, and a water supply line (or water supply) for replenishing water or discharging contaminated water Old) and drain may be provided in the water tank.

Hereinafter, a process for removing fine dust through an apparatus according to an exemplary embodiment of the present invention will be described with reference to FIGS. 4 to 6 as follows.

First, as shown in Figure 4, the water supplied from the water tank 4 along the water supply pipe 5 is through the water discharge hole 5ab of the distribution pipe 5a located on the uppermost inclined guide plate 2a. It is discharged to the top smooth surface ps of the guide plate 2a and is evenly supplied to the front and rear slopes of the inclined guide plate 2a. The water supplied as described above spreads evenly over all of these inclined surfaces and forms a thin water film wm, descends and flows into the water pedestal 3a below it.

As described above, the water flowing into the upper water pedestal 3a is discharged downward through a through hole o formed in the center of the bottom 3aa of the water pedestal 3a, as shown in FIG. (o) The water flowing down passes through the center of the through hole (o) and rides the front and rear sides of the vertical ribs (vr) of the inclined guide plate (2b) extending upwards to the bottom of the inclined guide plate (3b). It forms a water film on the front and rear slopes and rides down.

Subsequently, the water flowing from the inclined guide plate 2b to the water pedestal 3b below it passes through the same process as in the previous case and passes through the inclined guide plate 2c at the bottom, as shown in FIG. 6, to the water pedestal 3c. ).

The water flowing into the lower water support 3c is collected back into the water tank 5 through the pipe 4a to repeat the water circulation process as shown in FIG. 4.

As described above, in the apparatus of the present invention, the water film flowing on the inclined guide plates 2a, 2b, and 2c installed vertically and in multiple stages is continuously formed in the process of continuously circulating water, and the air through the water film on the inclined guide plate is continuously formed. The removal of fine dust in the middle is performed.

In other words, the atmosphere moves in the transverse direction due to the difference in air pressure between regions, and as a result of the convection of the longitudinal convection phenomenon due to the temperature difference between the surface and the upper layer, the fine dust contained in the atmosphere moves with the movement of the atmosphere. In the course of passing through the device of the present invention installed on the movement path between these movements, it comes into contact with the water film formed on the surface of the inclined guide plate, and through such contact, fine dust or moisture particles contained in the atmosphere Alternatively, the fine dust contained in the smog is adsorbed into the water film of the inclined guide plate through the adsorption properties of water.

On the other hand, in the apparatus of the present invention, as shown in Figures 4 to 6, the air passage wd is formed between the inclined guide plates vertically adjacent to the water pedestal, and is included in the air passing through the air passage wd. The fine dust is absorbed by contact with water during the passage. At this time, the air passage (wd) has an inclined surface on one side of the lower inclined guide plate centered on the water pedestal, and an upward flow of the upwards flows into the space inside the water pedestal through the gap between the vertical rib of the inclined guide plate and the through hole of the water pedestal. After inflow, a path exiting through the gap between the opposite end of the upper inclined guide plate and the outer bend of the water pedestal is taken.

The air passage wd has a role of increasing the removal efficiency of fine dust and also exhibits an effect of lowering the risk of damage or damage to the device by external force when the wind strength is strong.

7 is a perspective view of a device according to another embodiment of the present invention, and is made of the same structure as the device of FIGS. 2a, 2b, 2c) in order to prevent damage to the water film according to a limit in blocking the lateral wind through the side frame 1 in the case of being long, the same as the side frame in many places between the side frames 1 The difference is shown in that the intermediate barrier rib 6 having a width is formed.

In addition to this, the water tank 4 and the water supply pipe 5 are also installed compared to the device of FIG. 1.

On the other hand, the embodiment device according to the present invention has been described as an example in which the inclined guide plate installed between both side frames is installed in three stages up and down, but the inclined guide plate varies depending on the installation site conditions of the apparatus of the present invention. It can be changed and installed.
