The present invention relates to a system for reducing environmental pollution, and more particularly, to a sound barrier system capable of reducing various environmental pollution on a road.

With the progress of industrialization and urbanization, the problem of air pollution in the living environment becomes more and more serious. Such air pollution can cause various social damages including respiratory diseases, and the cost of social damages is increasing.

1 is a table showing the social damage costs due to air pollution. The table presented was provided by the Korea Institute for Environmental Policy and Evaluation (KEI) in 1999. According to the table, the social damage costs due to air pollution were 6.6% to 12.5% of Gross National Income in 1999 (average 9.6%). This is an amount corresponding to about 670,000 to 1,270,000 won (average 970,000 won) per person per year.

Representative examples of such air pollutants include exhaust gas or fine dust of vehicles on roads, and a method of cleaning roads using vehicles is currently used to remove them.

As a method for cleaning roads using vehicles, vacuum vehicles and sprinkler vehicles are mainly used.

First, the method of using a vacuum vehicle is a method of sweeping the road surface by using an electric brush mounted on the car, and vacuum suction of the generated dust. The method of using a spray vehicle is to spray water on the road surface using a car to remove dust on the road surface. How to wash.

However, since these methods clean the road using a vehicle, air pollution may occur again to operate the equipment and there may be a traffic accident.

In addition, there is a problem in that the equipment available professional personnel must be permanently resident, not only takes a lot of maintenance costs, but also can not be continuously cleaned due to the limitation of the capacity of the fuel tank or water tank of the vehicle.

In addition, the vacuum vehicle using method requires expensive equipment, and the spraying vehicle using method may cause complaints due to water splashing on pedestrians or vehicles.

In addition, although most of the fugitive dust and exhaust gas and the like floating in the air according to the actual vehicle driving, both methods have a limitation that only the fine dust on the road floor can be removed.

The present invention has been made to solve the above-mentioned conventional problems, can be carried out continuously with a low maintenance cost without causing any pollution or traffic problems due to the equipment operation, fine dust on the road surface as well as air It is an object of the present invention to provide an air pollution reduction system that can effectively remove fugitive dust in the air.

In order to achieve the above object, an environmentally soundproof wall system according to the present invention includes a soundproof wall part, a pollution degree detecting part, and a water spraying part. The noise barrier blocks the noise generated on the road, the pollution detector detects the degree of environmental pollution around the preset sound barrier, and the water spray unit sprays water into the atmosphere when the detected degree of environmental pollution is outside the preset standard.

As such, by detecting the degree of environmental pollution around the sound barrier and spraying water into the air according to the detected degree of environmental pollution, the equipment can be continuously operated with low maintenance costs without causing any pollution or traffic problems. It can be carried out, it is possible to effectively remove not only fine dust on the road surface but also scattering dust in the atmosphere.

The preset environmental pollution may be air pollution or may be above the temperature. In this way, it is possible to detect the degree of air pollution or temperature and to take measures to mitigate the problem of air pollution and temperature or higher depending on the degree of air pollution and temperature or higher.

The water spray unit may spray water to form a water film outside the soundproof wall, or may spray water to reach a position on a predetermined road surface. Due to this configuration, it is possible to apply the most suitable type of water spraying method according to various types of contamination.

The eco-friendly soundproof wall system may further include a power supply unit for supplying self-generated power to at least one of a pollution degree detection unit and a water spray unit, and the power supply unit may include at least one of a solar power generation unit, a wind power generation unit, and a piezoelectric generation unit. have. As such, by employing an eco-friendly power generation device in the soundproof wall system, it is possible to solve the problem of inconvenience or environmental pollution that may occur when receiving power from the outside.

The eco-friendly soundproof wall system may further include a regeneration water supply unit for supplying water to the water spray unit, and the regeneration water supply unit may supply heavy water or stored rainwater of the heavy water. This configuration eliminates the need for a separate water supply from the water supply for system operation, resulting in cost savings and environmental protection.

According to the present invention, by applying the IT technology to the sound barrier can be continuously carried out with low maintenance costs without causing any pollution or traffic problems due to the equipment operation, even fine dust on the road surface as well as scattering dust in the air It can be removed effectively.

In addition, it is possible to solve not only air pollution generated on the road, but also environmental pollution such as noise and heat islands generated on the road.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

Figure 2 is a schematic block diagram of one embodiment of an environmentally soundproof wall system according to the present invention.

In FIG. 2, the eco-friendly soundproof wall system 100 includes a soundproof wall unit 110, a pollution degree detecting unit 120, a water spraying unit 130, a power supply unit 140, and a renewable water supply unit 150, and the power supply unit 140 again. It includes a solar power generation unit 142, a wind power generation unit 144, and a piezoelectric power generation unit 146.

The soundproof wall unit 110 refers to a general soundproof wall body that performs a function of blocking a noise generated in a road from the outside.

As interest in the environment increases, the application of design and construction methods considering the natural environment in urban planning is increasing, and as a result, the installation of environmental facilities for maintaining a pleasant environment is also increasing.

Representative examples of such environmental facilities include soundproof walls. Soundproof wall is a wall installed to block the incoming sound or the sound emitted from the room to other places. It is mainly installed around the road to block the noise generated on the road from reaching the area around the road. .

Such road noise barriers are mainly installed to block noise, so they are installed between the place where the noise is generated and the place where the person who hears the noise is located. At this time, since sound is transmitted in the form of waves, soundproof walls are manufactured in consideration of the law of motion of waves, and it is common to make the height high or the thickness thick.

In addition, the sound barrier is manufactured by using a special material and structure that can absorb sound waves, and in Korea, the sound barrier is manufactured and installed according to the standards announced by the Ministry of Environment, which includes not only functional aspects but also aesthetics and safety aspects. To consider.

Accordingly, sound barriers are applied in various facilities and spaces to block noise such as residential, office, school, etc. adjacent to urban roads. Recently, vegetation is considered in consideration of ecological functions, and transparent sound barriers are considered in consideration of landscape. It is becoming.

However, such a conventional sound barrier mainly performs the function of blocking the noise generated on the road, but it does not provide any solution to environmental problems such as air pollution or heat island phenomenon, which is recently gaining attention. Therefore, there is a problem that increases the environmental pollution even more.

In the present invention, by detecting the degree of environmental pollution around the soundproof wall, and spraying water in the air in accordance with the detected degree of environmental pollution, as well as the noise generated on the road as well as the environmental pollution such as air pollution or heat island phenomenon occurring on the road Problems can also be solved.

In addition, since a device for water spraying is installed on the soundproof wall, a separate structure for installing the water spraying device is unnecessary, and since the soundproof wall itself has a considerable height, it can be varied depending on the installation position or the water spraying direction of the water spraying device. Mode water spraying is possible.

The pollution degree detecting unit 120 detects the degree of environmental pollution around the soundproof wall set in advance.

The preset environmental pollution may be air pollution or may be above the temperature. In this regard, the pollution degree detecting unit 120 may be an air pollution detecting sensor and a temperature abnormality detecting sensor, respectively, and a fine dust detecting sensor, a COx sensor, a SOx sensor, and the like may be employed as a sensor for detecting air pollution. As a sensor for detecting an abnormality, a temperature sensor, a humidity sensor, or the like may be employed. In addition, the pollution detector 120 may be implemented by employing various sensors of various types capable of detecting various types of environmental pollution.

 In this way, it is possible to detect the degree of air pollution or temperature and to take measures to alleviate the problem of air pollution and temperature or higher depending on the degree of air pollution and temperature or higher.

The water spray unit 130 sprays water into the atmosphere when the detected degree of environmental pollution is out of a predetermined standard. The preset criterion is a criterion set in advance by the manufacturer or the user of the soundproof wall system, and the set value may be changed according to the position where the soundproof wall system 100 is installed.

In addition, the water spraying unit 130 may spray water to form a water film outside the soundproof wall unit 110, or may spray water to reach a predetermined road surface position. This selection may be automatically performed by the user's input of the sound barrier wall system 100 or by a criterion set in advance in the sound barrier wall system 100.

Since the water spraying unit 130 is installed at various locations on the soundproof wall and can perform water spraying in various modes, the mode is selected according to a preset criterion to perform water spraying in various forms.

This selection is performed according to the detection result of the pollution degree detecting unit 120, and is performed as necessary, such as adsorption removal of air pollutants, reduction of heat island phenomenon around the soundproof wall through evaporation of evaporation heat, water supply for surrounding vegetation, and road surface cleaning. Can be.

FIG. 3 is a view schematically illustrating an example of water spraying of the environment-friendly sound barrier system of FIG. 2.

As shown in FIG. 3, water is sprayed from the upper side of the soundproof wall to remove fine dust through mist spray for improving air quality, or road surface temperature reduction and fine dust removal may be performed by forming a water film around the soundproof wall. In addition, water spraying from the lower side of the soundproof wall to the road surface can reduce the road surface temperature and supply water to surrounding plants.

In this case, the water used may be rainwater, heavy water discharged from surrounding buildings, or water stored in a storage tank, and in this case, since water is not separately supplied for water spraying, it may reduce inconvenience or cost for a separate water supply. Will be.

Due to this configuration, it is possible to apply the most suitable type of water spraying method according to various types of contamination.

The power supply unit 140 supplies power to various devices of the sound insulation wall system 100 including the pollution degree detecting unit 120 and the water spraying unit 130. In this case, the power supply unit 140 may supply power generated by itself for power supply, instead of receiving power from the outside. As such, when the eco-friendly power generation device is adopted as the soundproof wall system, it is possible to solve the problem of inconvenience or environmental pollution that may occur when the power is supplied from the outside.

In addition, it is possible to use environmentally friendly power generation such as solar power, wind power generation, or piezoelectric power generation for its own power generation. Accordingly, in FIG. 2, the power supply unit 140 includes a solar power generation unit 142, a wind power generation unit 144, and a piezoelectric power generation unit 146.

However, in FIG. 2, although the power supply unit 140 includes three power generation units, in other embodiments, only some of the three power generation units may be employed, and other eco-friendly power generation devices capable of self-power generation may be partially implemented. It can be used in place of or in addition to the three developments.

As such, by detecting the degree of environmental pollution around the sound barrier and spraying water into the air according to the detected degree of environmental pollution, the equipment can be continuously operated with low maintenance costs without causing any pollution or traffic problems. It can be carried out, it is possible to effectively remove not only fine dust on the road surface but also scattering dust in the atmosphere.

4 is a schematic flowchart of a process of operating the eco-friendly sound barrier system of FIG.

In FIG. 4, when the vehicle first enters the installation area of the environmentally soundproof wall system 100, fine dust and vibration occur on the road surface as the vehicle passes. At this time, the power source 140 of the eco-friendly soundproof wall system 100 accumulates vibration energy as electrical energy and performs self-generation using the generated vibration.

In this case, the self-generation is described as being performed by the piezoelectric element installed under the road surface, as mentioned previously, various types of eco-friendly self-powering means may be employed.

In addition, the pollution degree dust detection unit 120 detects the scattering fine dust generated by the vehicle entered. At this time, the pollution degree detection unit 120 may employ a non-power sensor for the detection of scattering dust, and in consideration of the convenience of installation, such a non-power sensor is preferable, but an external power supply type sensor may be used. A sensor driven using power generated by the power supply unit 140 may be employed.

Finally, the water spraying unit 130 removes the scattering dust through the water spray according to the pollution degree detected by the pollution degree detecting unit 120. In this case, although the water spray unit 130 is used to adsorb fine dust, it may be used for the purpose of supplying water to the surrounding vegetation or prevention of heat island phenomenon. As described above, it may be performed in various forms such as spraying to a road surface, water film formation, and the like.

In addition, at this time, the power produced and stored in the power supply unit 140 may be used for driving the water spraying unit 130, and this type of power supply may be preferable, but when the stored power is insufficient, externally produced power may be additionally supplied. will be.

The regeneration water supply unit 150 supplies the heavy water or the stored rainwater of the heavy water to the water injection unit 130. This configuration eliminates the need for a separate water supply from the water supply for system operation, resulting in cost savings and environmental protection.

Water is the water used to purify rainwater, cooked water, or bath water and send it to a separate pipe for reuse in flushing toilets, which can reduce the cost of system operation.
