Description

흡음 및 오염물질제거 기능을 갖는 도로용 분리대{A GUARDRAIL FOR ROAD WITH PREVENTION OF AIR POLLUTION AND NOISE}Road separator with sound absorption and pollutant removal {A GUARDRAIL FOR ROAD WITH PREVENTION OF AIR POLLUTION AND NOISE}

본 발명은 도로상에서 차도와 차도 또는 차도와 인도를 구획하는 도로용 분리대에 관한 것으로서, 더욱 상세하게는 분리대가 차량으로부터 발생되는 소음제거 기능과 더불어 배기가스로 인한 오염물질 제거 기능을 갖도록 하여 도로의 환경이 보다 깨끗하게 유지되도록 하는 흡음 및 오염물질 제거 기능을 갖는 도로용 분리대에 관한 것이다.The present invention relates to a road separator that separates a roadway and a roadway or a roadway and a sidewalk on a road. More specifically, the roadside separator has a noise removal function generated from a vehicle and a pollutant removal function by exhaust gas. It relates to a road separator having sound absorption and pollutant removal functions to keep the environment cleaner.

도로상에 제공되는 분리대는, 도로의 중앙을 구획하는 중앙선 또는 도로와 인도를 구획하는 외측선 구획라인에 제공되어 차량 또는 보행자의 안전을 도모하게 된다.The separator provided on the road is provided on a center line that divides the center of the road or an outer line dividing line that divides the road and sidewalks, thereby promoting safety of the vehicle or pedestrian.

이러한 분리대는, 통상 콘크리트 거푸집 또는 환봉의 포스트 양쪽에 제공되는 철판 등으로 제작되며, 이는 차량 부딪힘시 차량의 외부 이탈 또는 차량의 충격을 일부 흡수하여 안전사고를 미연에 방지하고자 하는 것이다. 즉, 상기 분리대는 전술한 바와같이 안전사고를 방지하는 것이 주된 목적이다.Such a separator is usually made of a steel plate or the like provided on both sides of a concrete formwork or round bar, which is intended to prevent safety accidents by absorbing some of the vehicle's exterior deviation or the impact of the vehicle. That is, the separator is the main purpose of preventing a safety accident as described above.

하지만, 도로상에는 분리대와 더불어 주행하는 차량의 소음이 외부 즉, 도로 주변의 주택 또는 건물 등으로 전달되지 않도록 요구하게 되며, 이를 해결하기 위해 도로상에는 분리대 외에 방음벽이 추가로 설치되게 된다.However, it is required that the noise of the vehicle traveling with the separator on the road is not transmitted to the outside, that is, the house or building around the road, and to solve this problem, a noise barrier is installed on the road in addition to the separator.

종래의 방음벽은, 도로 변의 지면이나 교량의 가장자리 외측에 제공되는 것이며, 일정 간격으로 세워진 지주(H-Post)와 지주 사이에 방음판을 끼워 설치하고, 그 내측에는 흡음재를 채움시켜 소음을 차단 및 흡수하게 된다.Conventional soundproof walls are provided outside the edges of the roadside or bridges, and are fitted with soundproof boards sandwiched between H-posts and struts that are erected at regular intervals, and filled with sound-absorbing material inside to block and absorb noise.

이렇게 도로상에는 차량의 안전 그리고 소음 해소 등을 해결하기 위해 분리대와 방음벽이 필수적으로 제공되고 있으나, 좁은 도로상에서의 분리대와 방음벽 설치는 오히려 도로의 미관을 크게 해치는 문제점을 갖게 된다.In order to solve the safety of the vehicle and the noise on the road as described above, the separator and the soundproof wall is essentially provided, but the installation of the separator and the soundproof wall on the narrow road has a problem that greatly hurts the aesthetics of the road.

이에 본 발명은 상기한 문제점을 해결하기 위해 창안된 것으로, 본 발명의 목적은 도로상에서 차도와 차도 또는 차도와 인도를 구획하는 분리대가 차선의 분리 또는 차량 소음의 제거 기능과 더불어 배출가스에 의한 오염물질의 제거 기능을 동시에 갖도록 하는데 있는 것이다.Therefore, the present invention was devised to solve the above problems, and an object of the present invention is to separate the lanes and the roads or the roads and the sidewalks on the road, and to separate the lanes or remove vehicle noises, and pollution by the exhaust gas. It is to have the function of removing material at the same time.

본 발명의 다른 목적은, 분리대가 구간별로 분리 및 해체 작업이 용이하도록 하여 부분 파손시 부품 교체가 용이하도록 하는데 있는 것이다.Another object of the present invention, the separator is to facilitate the separation and disassembly operation for each section to facilitate the replacement of parts in case of partial breakage.

When the cover 130 and 220 are coupled to the upper end of the frame member 200 and the upper end of the post 100, the assembly is completed.

도 5는 본 발명에 따른 전후면판의 광촉매가 유기오염물을 분해시키는 과정을 도시한 것이다.5 illustrates a process in which the photocatalyst of the front and rear plates according to the present invention decomposes organic contaminants.

본 발명에 따른 광촉매는, 산화티탄(TiO2)을 주성분으로 하며 산화티탄에 마그네슘, 백금, 팔라듐, 니켈, 몰리브덴, 지르코늄, 크롬 중 하나를 첨가하여 얻어진다.The photocatalyst according to the present invention is obtained by adding titanium oxide (TiO 2 ) as a main component and adding one of magnesium, platinum, palladium, nickel, molybdenum, zirconium and chromium to titanium oxide.

광촉매는, 광(Phonon)이 Carrier(촉매 담체)에 쐬어졌을 때 Carrier(촉매 담체)의 내부에 있는 촉매가 여기 되어 주변의 오염물질을 분해하게 된다.In photocatalyst, when Phonon is picked up by Carrier (catalyst carrier), the catalyst inside Carrier (catalyst carrier) is excited to decompose surrounding pollutants.

즉, 촉매에 빛을 조사하면 촉매가 빛 에너지를 받아 촉매 내부에서 전자들의이동이 일어나고, 이동된 전자들이 강력한 화학작용(산화,환원)을 일으킨다. 이때 전자들의 강력한 화학작용은 오염된 물질을 산화시켜 무해한 물질로 변화를 주는 과정을 말한다.That is, when light is irradiated to the catalyst, the catalyst receives light energy, causing the movement of electrons in the catalyst, and the moved electrons cause a strong chemical reaction (oxidation, reduction). At this time, the strong chemical reaction of electrons refers to the process of oxidizing contaminated material and transforming it into harmless material.

다시말해, 광촉매 표면에 광이 조사되면 입자에 전자가 여기되어 e-와 h+를 형성하고 형성된 e-와 h+는 대기중의 H2O 와 O2와 반응하여 OH 와 O2 -를 형성한다. 연속해서 OH 와 O2 -는 표면에 부착된 유기 오염물과 산화 환원 반응을 진행하며 이 산화 환원 반응의 결과로 유기 오염물은 CO2와 H2O 로 완전 분해된다.In other words, when light is irradiated electrons are excited to the particles e to the photocatalyst surface, and h + is OH and O 2 reacts with H 2 O and O 2 in the air-and h + e is formed and formed to form a do. Subsequently, OH and O 2 undergo a redox reaction with organic contaminants attached to the surface. As a result of the redox reaction, organic contaminants are completely decomposed into CO 2 and H 2 O.

도 6은 광촉매의 초친수성 과정을 도시한 것이다.Figure 6 illustrates the superhydrophilic process of the photocatalyst.

즉, 자외선에 의해 광촉매 유기물 분해 과정에 의해 오염물이 분해되면 깨끗한 산화티탄(TiO2)이 광촉매 표면에 노출되고 이때 대기중의 H2O와 반응하여 친수성 -OH 그룹이 표면에 생성되며 동시에 대기중의 H2O와 결합하여 초친수성을 발현하게 된다.That is, when contaminants are decomposed by photocatalytic organic matter decomposition by ultraviolet light, clean titanium oxide (TiO 2 ) is exposed to the surface of the photocatalyst and reacts with H 2 O in the atmosphere to form hydrophilic -OH groups on the surface and at the same time In combination with H 2 O will express the superhydrophilicity.

상기한 광촉매의 원리로 광촉매에 빛이 조사되면 대기중의 유해한 물질을 분해하여 무해한 물질로 변화시켜주게 된다. 즉 광촉매는 산화력이 크기 때문에 오염물을 분해하는데 충분한 에너지를 갖고 있다.When light is irradiated to the photocatalyst on the principle of the photocatalyst, it decomposes harmful substances in the atmosphere and converts them into harmless substances. That is, the photocatalyst has a high oxidizing power and has enough energy to decompose contaminants.

예를 들면, OH는 하이드록시 라디칼이라고 불려지는 분자로서 산소나 오존(O3) 보다도 강한 산화력을 가지는데 광촉매는 H2O를 분해하여 H와 OH로 분해시켜 높은 산화력을 가지게 해준다.For example, OH is a molecule called hydroxy radical, which has a stronger oxidizing power than oxygen or ozone (O3). The photocatalyst decomposes H 2 O into H and OH to have high oxidizing power.

이렇게 분해된 오염물질은 빗물 등에 의해 씻겨져 전후면판은 별도의 청소작업 없이도 분리대의 청결상태를 유지할 수 있게 된다.The contaminants decomposed in this way are washed by rainwater, and the front and rear plates can maintain the cleanliness of the separator without a separate cleaning operation.

따라서, 본 발명에 따른 흡음 및 오염물질제거 기능을 갖는 도로용 분리대는, 도로상에서 차도와 차도 또는 차도와 인도를 구획하는 분리대가 내부에 차량으로부터 발생되는 소음을 흡수하도록 흡음재가 구비되고, 또한 분리대를 이루는 전후면판에 광촉매가 코팅되어 차량으로부터 발생되는 소음 및 배출가스에 의한 오염물질의 제거 기능을 동시에 이룰 수 있는 효과가 있다.Accordingly, the road separator having sound absorption and pollutant removal functions according to the present invention is provided with a sound absorbing material so as to absorb the noise generated from the vehicle in the separator partitioning the driveway and the driveway or the roadway and the sidewalk on the road. The photocatalyst is coated on the front and rear plates to form a function of removing pollutants by noise and exhaust gas generated from the vehicle at the same time.

또한, 분리대가 구간별로 분리 및 해체 작업이 용이하게 되어 부분 파손시 부품 교체 및 청소작업이 용이하게 이루어지는 효과가 있다.In addition, the separator is easy to separate and dismantle each section, there is an effect that makes it easy to replace and clean the parts when part breakage.

또한, 광촉매에 의해 분해된 이물질은 빗물 등에 의해 쉽게 씻겨져 별도의 청소작업 없이도 분리대의 청결상태를 유지할 수 있는 효과가 있다.In addition, the foreign matter decomposed by the photocatalyst is easily washed by rain water, etc., there is an effect that can maintain the clean state of the separator even without a separate cleaning operation.
