Description

{System for reducing road pollutant emission}

The present invention relates to a system for reducing road pollutant emissions. More specifically, the present invention relates to a system for reducing road pollutant emissions, and more specifically, to solve the problem of the roadway being flooded or causing bad odors due to blockage of drains in the roadway by cigarette butts, etc., and at the same time, the problem of vehicle wind naturally occurring when the vehicle is driven. The fugitive dust that moves to the border of the roadway is guided and collected inside the reduction device, and then discharged into the sewer pipe along with rainwater through the drainage channel provided inside the device, thereby dramatically reducing harmful fugitive dust on the roadway and protecting pedestrians. It is about a road pollutant emission reduction system that can improve the health of people and prevent air pollution caused by fugitive dust.

Dust emitted from roadways into the air is one of the main causes of air pollution.

There is fugitive dust emitted when tires or brakes wear out from vehicles driving on the roadway, and re-fusing dust where dust accumulated on the surface of the roadway is scattered into the air by the driving of a car or wind.

Figure 1 shows the concentration distribution of dust flying in a typical roadway situation.

After a car (C) passes on the roadway (10), the concentration distribution of fine dust (D) at the location of the general roadway boundary stone (30) is 76.4% up to 0.5m from the ground, 88.1% up to 1.0m, and the highest below 1.0m. It occurs and is known to increase as the height decreases, so it appears highest at the roadway boundary stone (30).

Generally, the roadway boundary stone 30 is installed higher than the roadway 10 along the edge of the roadway to mark the boundary of the roadway 10, and because the roadway 10 and the roadway boundary stone 30 form a protruding structure. Flying dust (D) and re-flying dust moved by the vehicle wind generated when the vehicle (C) is driven are likely to be deposited.

A large amount of roadway dust (D) deposited in this way is continuously re-dispersed due to vehicle wind and natural wind, not only causing direct damage to people passing on the adjacent sidewalk (20), but also seriously affecting the atmospheric environment around the roadway.

Conventionally, in order to solve this problem, efforts have been made to periodically remove accumulated dust using driveway sweepers, dust suction trucks, etc., but there was a problem in which fine dust deposited before cleaning was continuously re-dispersed.

In addition, water and manpower are consumed, and water containing air pollutants is always stagnant around the roadway, damaging the aesthetics of the roadway. Normally, the water accumulated around the roadway evaporates quickly due to sunlight, and air pollutants still remain near the roadway, so there is a risk that it may be re-dispersed into the air due to vehicle and natural wind.

Figure 2 is a longitudinal cross-sectional view of the main part showing the drain of a conventional driveway. Referring to the figure, the conventional drain is usually installed at the boundary between the driveway 10 and the sidewalk 20, and a water collection well 40 is buried in the ground. A grating (50) is installed at the top of the water collection basin (40) parallel to the ground, so that pollutants such as dust drifting on the roadway during rainy weather are channeled into the water collection basin (40) at the bottom through the grating (50) along with rainwater. It is configured to drain.

However, since the grating 50 in the drain of the conventional driveway is installed upward, cigarette butts often get caught in the grating, and when the grating is blocked by cigarette butts or various pollutants, dust cannot flow in. In addition, due to poor drainage during rainy weather, the roadway was flooded.

In addition, as various pollutants such as cigarette butts accumulated inside the drain decay, a foul odor rises through the grating 50, causing discomfort, and when the various pollutants flow into the river, they have a negative impact on the environment, such as the death of fish. Problems arising repeatedly occurred.

Therefore, the development and development of a road pollutant emission reduction system that effectively removes flying dust on the roadway using vehicle wind without harming the health of pedestrians using the sidewalk and the surrounding environment such as rivers, is easy to install and maintain, and is low cost. Supply is urgently needed.

This is a diagram of the installation state of the road pollutant emission reduction system, (a) a first embodiment in which the sump is buried in the roadway, and (b) a second embodiment in which the sump is buried in the sidewalk.

Referring to FIGS. 3 to 7, the road pollution source emission reduction system of the present invention includes a road pollution source emission reduction device 100, a water collection well 200, and a second drain pipe 300.

First, looking at the configuration of the road pollutant emission reduction device 100, the body part ( 110) is installed. The body portion 110 has a space open downwardly formed therein and has a side opening 110a (see FIG. 5) on one side of the space open toward the roadway.

In addition, a filtering unit 120 in the form of a mesh or slit is installed in the side port 110a of the body 110 in an upright state at a certain height from the ground. Accordingly, the filtering unit 120 passes small pollutants, such as dust below a certain particle size, among the pollutants scattered from the roadway 10, and filters out large pollutants, including cigarette butts, exceeding a certain particle size.

In addition, a drainage guide part 130 is provided at the lower part of the body part 110 in a buried state. According to one embodiment, a drain passage 130a (see FIG. 5) that is open upward is formed inside the drainage guide portion 130, and the open upper end of the drain passage 130a is of the body portion 110. By communicating with the space, dust flowing into the side port 110a through the filter 120 due to vehicle wind is collected at the bottom of the drain passage 130a.

In addition, the drain passage 130a of the drain guide 130 is formed in a slit shape to communicate with the open space inside the body 110, and the drain guide 130 has a side opening of the body 110. (110a) A circular outlet hole 130b is formed on one side of the same or opposite side.

Also, referring to FIG. 6, the drain passage 130a has an open top and the open top communicates with the space inside the body portion 110, and the drain passage 130a is located at the bottom of the drain passage 130a. ) An inclined surface 131 is formed to guide the flow of rainwater from the open top of the drain guide unit 130 to the outlet hole 130b. That is, small particle size contaminants such as dust that pass through the filter 120 of the present invention accumulate on the inclined surface 131 formed at the bottom of the drain passage 130a.

According to one embodiment, the inclined surface 131 may have an angular shape (see FIG. 6A), or according to another embodiment, the inclined surface 131 may have a round shape (see FIG. 6B).

In addition, a damper unit 140 is installed at the outlet hole 130b of the drainage guide unit 130. Referring to FIG. 3, the damper unit 140 is closed in normal times and receives dust introduced through the filter unit 120 and the drain passage 130a.

In this state, as shown in FIG. 4, when rainwater flows in through the filter unit 120 and the drainage passage 130a, the damper unit 140 is opened by the load of the rainwater and dust is discharged together with the rainwater. . In addition, the damper unit 140 maintains a closed state in normal times to prevent bad odors inside the water sump 200 from leaking out of the water sump 200.

Also, referring to FIG. 7, a water collection well 200 is buried underground at the bottom of the roadway 10 or sidewalk 20. The water collection well 200 receives rainwater and dust discharged from the outlet hole 130b of the drainage guide unit 130 when the damper unit 140 is opened due to the load of rainwater during rainy weather.

Specifically, according to the first embodiment of FIG. 7A, the water collection well 200 may be buried underground at the bottom of the roadway 10. At this time, the outlet hole 130b of the water collection well 200 and the drainage guide part 130 is in contact with or spaced apart from each other (shown as spaced apart in Figure 7a), and one end of the first drain pipe 150 is connected to the drain guide part. It is inserted into the outlet hole (130b) of (130) and the other end penetrates the water collection well (200) and is connected to the inside of the water collection well (200). Therefore, even if the outlet hole 130b of the water collection well 200 and the drainage induction part 130 are spaced apart from each other, the length of the first drain pipe 150 is adjusted to determine the outlet hole 130b of the water collection well 200 and the drainage induction part 130. ) can be extended.

Meanwhile, according to the second embodiment of FIG. 7B, the water collection well 200 may be buried underground at the bottom of the sidewalk 20 on the opposite side of FIG. 7A. At this time, the outlet hole 130b of the water collection well 200 and the drainage inducing part 130 is in contact with or spaced apart from each other (shown in a contact state in FIG. 7b), and one end of the first drain pipe 150 is in the drainage inducing part. It is inserted into the outlet hole (130b) of (130) and the other end penetrates the water collection well (200) and is connected to the inside of the water collection well (200).

In addition, a first drain pipe 150 is provided between the outlet hole 130b of the drain guide part 130 and the damper part 140. Here, the first drain pipe 150 performs the function of connecting the spaced water sump 200 and the drainage guide part 130 to each other when there is a gap between the water sump 200 and the drainage guide part 130. That is, after preparing the first drain pipe 150 having a length that matches the gap between the water collection well 200 and the drainage guide part 130, it is inserted between the spaced water collection well 200 and the drainage guide part 130. Put them together and connect them together.

Additionally, at least one second drain pipe 300 is provided on one side of the water collection well 200. The second drain pipe 300 connects the water collection well 200 and a surrounding sewer pipe (not shown). Accordingly, as the damper unit 140 is opened during rainy weather, rainwater and dust flowing into the water collection well 200 are finally discharged into the surrounding sewer pipe (not shown) through the second drain pipe 300.

In addition, an opening (not shown) communicating with the roadway 10 is formed on the upper surface of the water sump 200, and a cover 210 is provided at the opening. The cover 210 is preferably formed in a closed form rather than the grating form seen in the related art. As shown in FIGS. 3, 4, and 7, in the state where the cover 210 blocks the opening of the water sump 200, It is understandable that rainwater cannot flow into the catch basin through the opening. Meanwhile, in the field, workers can perform tasks such as cleaning the inside of the water sump 200 after opening the cover 210 when necessary.

In addition, the filter 120 is formed of expanded metal, and is in contact with or close to one side of the sump 200 or the roadway 10. ) protrudes upward from the upper surface by a certain height.

Accordingly, large pollutants such as cigarette butts or larger than a certain particle size are caught in the filter unit 120 or do not pass through, so they are removed during cleaning, and small pollutants such as dust less than a certain particle size pass through the filter unit 120. It is accumulated at the bottom of the drainage passage (130a) of the drainage inducing part (130).

At this time, as seen above, in the case of a conventional drain, cigarette butts are caught between the gratings (50, see FIG. 2) or pass through the gratings (50) and accumulate inside the sump 40, and then inside the sump 40. There was a problem that cigarette butts accumulated in the water collection well 40 rotted inside or flowed into the river, damaging the environment. However, the filter unit 120 according to the present invention is attachable to the side port 110a of the body unit 110. Based on the pollutant to be blocked from inflow, such as a cigarette butt, an expanded metal having a mesh or slit-shaped hole with a particle diameter smaller than the cigarette butt is adopted to allow dust from vehicle wind to pass through, but the cigarette is Pollutants with large particle sizes, such as butts, are blocked from flowing into the water collection well (200).

For example, the size of the mesh or slit-shaped through holes is preferably small, at a few millimeters in size, to prevent contaminants such as cigarette butts from flowing into the river through the drain 231 and contaminating the river.

In addition, the size of the hole is sufficient so that contaminants such as cigarette butts do not pass through, but air, water or dust can pass through, and the shape of the hole may be circular, oval, square or rectangular, especially The shape of the through hole is not limited.

In addition, a separator (not shown) separating the roadway 10 and the sidewalk 20 or the roadway 10 and the roadway 10 may be further installed on the upper surface of the body portion 110. According to one embodiment, the separator (not shown) may be a separator for separating the roadway 10 and the sidewalk 20 or a central separator in the center of the roadway 10.

Therefore, the system of the present invention filters dust accumulated on the slope 131 at the bottom of the drainage passage 130a by passing through the filtration unit 120 due to vehicle wind (air + dust) on the road, and flows into the drainage passage 130a of the drainage induction unit during rainy weather. ), the damper unit 140 is opened by rainwater flowing into the water collection well 200 and can be discharged cleanly into the surrounding sewer pipe (not shown).

In addition, at least one part of the body portion 110, the drainage guide portion 130, and the water collection well 200 may be formed of stone, concrete, ceramic, plastic, or metal. For example, the upper part of the body 110 may be made of plastic or metal, and the lower part of the body 110 may be made of stone, concrete, or ceramic.

Additionally, the height of the body portion 110 may be installed higher than the height of the roadway 10. In this case, the body portion 110 can also serve as the boundary stone 30 by replacing the boundary stone 30 (see FIGS. 1 and 2) of the existing roadway 10 and sidewalk 20.

Meanwhile, the body portion 110 may replace a separator (not shown) installed on the roadway 10 or sidewalk 20 or may also serve as the separator (not shown). In this case, the body portion 110 may be designed in various shapes such as a square or a pentagon, and the height of the body portion 110 may be formed to be 1 m or more from the upper surface of the roadway 10.

Accordingly, as previously seen in FIG. 1, the system of the present invention can collect fine dust (D) corresponding to a concentration of 88.1% from the position of the general roadway boundary stone 30 to a height of 1.0 m. For example, when the height of the side opening 110a of the body 110 is 1 m or more, all fine dust at a concentration of 88.1% or more and close to 100% can be collected.

In addition, the filtering part 120 and the body part 110 are fastened by a separate fixing clip (not shown) or the body part 110 has a corresponding groove part (not shown) formed on at least one side of the filtering part 120. ) can be fastened to and fixed to a protrusion (not shown) formed on the side port 110a.

Additionally, the road to which the system of the present invention is applied may be an automobile roadway 10 or a train track. Accordingly, pollutants including dust are moved from the roadway 10 toward the body by the vehicle wind generated as the car or train runs, so pollutants such as cigarette butts, leaves, and plastic bags are filtered out by the filtering unit 120. Only pollutants with small particle sizes, such as dust, are filtered out and flow into the side port 110a through the filter 120.

Meanwhile, the flying dust on the road mentioned in the present invention consists of nitrate (NO3-), ammonium (NH4+), sulfate (SO42-), ozone, carbon compounds, metal compounds, volatile organic compounds, dioxins and odor-causing substances. It may include one or two or more selected from the group.

Hereinafter, the process of installing the road pollutant emission reduction system of the above-described configuration will be briefly reviewed as follows.

First, remove all of the curbstones (30) of the existing driveway (10) and the sidewalk (20), or the curbstone (30) of the driveway installed between the driveway (10) and the driveway (10), and then remove the soil around the existing curbstone (30) to a certain width and depth. Excavate with

Next, after installing the drainage guide portion 130 and the body portion 110 in order on the excavated ground surface, the side port 110a of the body portion 110 is protruded at a certain height from the roadway surface. Install the filter unit 120 in .

Next, the drainage guide part 130 and the water collection well 200 are connected to the first drain pipe 150, and then the damper part 140 is installed at the end of the first drain pipe 150, and the water collection well 200 and By connecting the surrounding sewer pipe (not shown) to the second drain pipe 300 and organizing the surrounding area, construction of the road pollutant emission reduction system of the present invention, which replaces the existing roadway curb 30, is completed.
