Abstract

The present invention relates to a tunnel air-exchange device, and more specifically to one in which: the air inside normal tunnels including tunnels through which vehicles run is cleaned and polluted internal tunnel air is expelled to the outside, to which end cold air, supplied to water tanks of different sizes provided in line at set intervals in the floor inside the tunnel, is used to ensure that the heavy soot and gases in the polluted hot air generated by vehicles, are sucked into the water tanks while the lighter foul air is discharged through chimneys by convection, thereby creating a pleasant tunnel environment by always maintaining clean air inside the tunnel; and which also extinguishes fires by spraying fire-extinguishing water during tunnel fires. Accordingly, the present invention combines a chimney effect with natural convection provided by the water tanks to exchange the air inside the tunnel and naturally expel polluted air, which is in contrast to exhaust fans of the prior art because there is no generation of noise or heat, and expenses can be reduced since there is no electrical consumption.

Description

자연 환기방식을 이용한 터널 환기장치Tunnel ventilation using natural ventilation
본 발명은 터널 환기장치에 관한 것으로서, 더욱 상세히 설명하면 차량이 통행하는 터널을 포함한 일반 터널 내부의 공기를 깨끗하게 함과 아울러 터널 내부의 오염된 공기를 외부로 배출하기 위한 터널환기장치는 터널 내부 바닥에 크기를 달리하여 일정간격으로 설치된 물탱크에서 공급되는 찬 공기가 터널 내부로 공급되어 차량에서 발생하는 오염된 더운 공기와 만나는 찬 공기에 의해 대류현상이 발생하여 하중이 무거운 매연, 가스는 물탱크로 흡입되고, 하중이 가벼운 나쁜 공기는 굴뚝을 통해 배출함으로 인해 터널 내부에는 항상 맑은 공기를 유지하여 쾌적한 환경을 제공함은 물론 터널 화재시에는 화재진압용 물을 분사하여 화재를 진압할 수 있는 자연 환기방식을 이용한 터널 환기장치에 관한 것이다.The present invention relates to a tunnel ventilator, and more specifically, a tunnel ventilator for cleaning the air inside a general tunnel including a tunnel through which a vehicle passes and discharging the polluted air inside the tunnel to the outside is a tunnel inner bottom. Cold air from water tanks installed at regular intervals of different sizes are supplied into the tunnel, and convection is caused by cold air that meets the polluted hot air generated from the vehicle. Air is sucked into the air, and the light air is discharged through the chimney to keep the fresh air inside the tunnel at all times to provide a pleasant environment. It relates to a tunnel ventilation apparatus using the method.
일반적으로, 차량이 통과하는 터널은 산을 뚫어서 콘크리트로 반원형 통로를 만든 것으로서, 상기한 터널은 양측만이 개방되어 있고 비교적 작은 공간으로 밀폐된 상태가 되기 때문에 터널 내부의 환기가 매우 중요하게 된다.In general, a tunnel through which a vehicle passes is made of concrete through a mountain to create a semi-circular passage. Since the tunnel is open on both sides and is sealed in a relatively small space, ventilation inside the tunnel becomes very important.
따라서, 터널 내부의 환기는 강제 배기를 해야 하는 바, 이를 위해 터널 내에는 다수의 대형 배기팬이 설치되어 있게 된다.Therefore, the ventilation inside the tunnel must be forced exhaust, for this purpose, a large number of large exhaust fans are installed in the tunnel.
즉, 터널의 천장에 비교적 큰 용량의 배기팬이 일정 거리마다 설치되어 터널 내부의 공기 및 먼지 등을 단계적으로 송풍시켜 외부로 배기시키도록 한다.In other words, a relatively large exhaust fan is installed at a predetermined distance in the ceiling of the tunnel to blow air and dust in the tunnel step by step to exhaust the air to the outside.
물론, 상기한 배기팬은 터널의 중앙부 천장에 터널의 방향에 맞춰서 수평으로 설치되어 배기팬의 송풍 방향이 일치되도록 배치되어 있게 된다.Of course, the exhaust fan is horizontally installed in the ceiling of the central portion of the tunnel in accordance with the direction of the tunnel is arranged so as to match the blowing direction of the exhaust fan.
그러나 상기한 바와 같이 터널 내부의 공기 및 먼지를 외부로 배기하기 위하여 터널 천정에 대형 배기팬을 다수 설치하게 되면, 상기한 배기팬이 동시에 작동하여도 터널 내부 공기를 외부로 배출하지 못하는 문제점이 있다.However, when a large number of large exhaust fans are installed on the ceiling of the tunnel to exhaust the air and dust inside the tunnel to the outside as described above, there is a problem that the air inside the tunnel cannot be discharged to the outside even when the exhaust fans are operated at the same time. .
즉, 터널의 길이가 길면 배기팬이 터널 내부 공기를 송풍하여도 일정 거리 이상 내부 공기가 이동하지 못하게 되고, 실질적으로 다음 배기팬까지 도달하지도 못한 상태에서 터널 전체로 확산되고, 따라서 다음 배기팬이 앞의 배기팬에서 송풍된 내부 공기를 전달받아 외부로 밀어내지 못하게 되는 바, 배기팬은 실질적으로 배기팬의 설치 영역 주위에서만 터널 내부 공기가 순환하게 하는 것에 불과하다.That is, if the tunnel length is long, the internal air does not move more than a certain distance even if the exhaust fan blows the air in the tunnel, and it diffuses through the tunnel in a state where the exhaust fan does not reach the next exhaust fan substantially. Since the internal air blown by the front exhaust fan cannot be pushed out to the outside, the exhaust fan substantially only allows the air in the tunnel to circulate only around the installation area of the exhaust fan.
또한, 터널 내부에는 차량이 고속으로 질주하기 때문에, 차량에 의해 생기는 공기 유동에 의해 터널 내부에 심한 와류가 발생하기 때문에 상기한 배기팬이 터널 내부 공기를 작은 공간에서만 순환시키고 외부로 배출하지 못한 게 된다.In addition, since the vehicle runs at high speed inside the tunnel, the air flow generated by the vehicle causes severe vortex inside the tunnel, so that the exhaust fan circulates the air in the tunnel only in a small space and does not discharge to the outside. do.
또한, 현재 시설된 기존의 터널은 배기팬에서 발생하는 소음, 열과 전력소모는 터널의 환경을 쾌적하게 유지하지 못하고 많은 전력소비로 인한 경제손실이 막대하다.In addition, existing tunnels that are currently installed, noise, heat and power consumption from the exhaust fan does not maintain the environment of the tunnel comfortably, the economic loss due to a lot of power consumption is enormous.
특히, 터널 내부에 설치된 배기팬은 매연 배출과 외부공기의 유입작용이 원활 하지못하여 터널 내부의 대류 역학적 친환경 보조장치가 요구되었다. In particular, the exhaust fan installed inside the tunnel, soot exhaust and inflow of the outside air was not smooth, the convective eco-friendly auxiliary device inside the tunnel was required.
따라서 상기와 같은 문제점을 해결하기 위한 본 발명은 터널 내부 환경을 자연 친화적인 방식에 의해 맑은 공기가 지속적으로 순환공급될 수 있도록 터널 바닥을 따라 일정한 간격으로 크기를 달리한 물탱크를 내설하여 터널 벽면을 통해 찬 공기를 공급함과 동시에 매연 및 가스를 흡입하는 물탱크 흡입 장치부와, 상기 물탱크 흡입장치부에 의해 매연과 가스가 분리된 더운 공기는 터널 벽면에 형성된 공기배출구를 통해 공기배출통로관을 거쳐 굴뚝으로 배출하는 자연 환기방식을 이용한 터널 환기장치를 제공한다. Therefore, the present invention for solving the above problems by installing a water tank of different sizes at regular intervals along the tunnel floor so that the clean air is continuously circulated supplying the environment inside the tunnel in a natural way to the tunnel wall surface A water tank suction device unit for supplying cold air and at the same time to suck the smoke and gas through the air, and the hot air separated from the smoke and gas by the water tank suction device unit is an air discharge passage pipe through the air outlet formed on the tunnel wall It provides a tunnel ventilation device using a natural ventilation method to discharge to the chimney through.
따라서, 본 발명은 종래의 터널 환기장치처럼 터널 내부의 공기를 터널 입구로 밀어내서 배출하는 게 아니라 터널 천장을 통해 흡입하여 굴뚝으로 배출하기 때문에 배출팬이 필요하지 않다. Therefore, the present invention does not push the air inside the tunnel to the tunnel entrance as in the conventional tunnel ventilation device, but discharges through the ceiling of the tunnel and discharges it into the chimney so that a discharge fan is not required.
이상에서 설명한 바와 같이 본 발명 자연 환기방식을 이용한 터널 환기장치는 터널 내부에 맑은 공기를 항시 공급하여 순환함으로써 쾌적한 상태를 유지할 수 있도록 대류현상과 굴뚝효과를 결합한 것으로서 터널 내부 바닥에 설치된 물탱크 시설에서 공급되는 지하수의 찬 공기와 차량에서 배출되는 더운 공기가 결합되어 대류현상이 발생하여 굴뚝으로 오염된 공기를 배출하고, 화재시 터널 내의 화재진압용 물을 일시에 대량 공급하여 화재를 진압하는 효과가 있다.As described above, the tunnel ventilation device using the natural ventilation method of the present invention combines the convection phenomenon and the chimney effect to maintain a pleasant state by circulating and supplying clean air at all times in the tunnel, and in the water tank facility installed at the bottom of the tunnel. Cold air from the ground water supplied and hot air from the vehicle are combined to generate convection and to release the polluted air through the chimney. have.
따라서 본 발명은 터널 내부의 공기를 자연 순환시키기 위해 물탱크 시설에 의한 대류현상과 굴뚝효과가 결합되어 오염된 공기를 자연 배출함으로써 기존의 배출팬 방식과 달리 소음, 열이 발생하지않고, 전력소비가 없기때문에 경제적 손실을 줄일 수 있는 효과가 있다.Therefore, the present invention is combined with the convection phenomenon and the chimney effect by the water tank facility to naturally circulate the air in the tunnel to discharge the polluted air naturally, unlike the conventional exhaust fan method does not generate noise, heat, power consumption There is no effect of reducing economic losses.
또한, 본 발명은 물탱크에 저장된 물을 터널 화재시 화재진압에 자동분사하여 사용할 수 있는 효과가 있다. In addition, the present invention has the effect that can be used to automatically spray the water stored in the water tank in the fire extinguishing fire in the tunnel.

본 발명 터널 환기장치는 대류현상과 굴뚝효과를 결합하여 터널(1) 내부의 공기를 지속적으로 순환 공급하여 쾌적한 환경을 제공할 수 있는 구조이다.The tunnel ventilation apparatus of the present invention is a structure that can provide a pleasant environment by continuously supplying the air in the tunnel (1) by combining the convection phenomenon and the chimney effect.
터널 환기장치는 터널(1) 바닥을 분할하여 터널(1) 벽면 양쪽에는 지속적으로 물탱크(2)에 공급된 물의 찬 공기를 공급하는 물탱크 흡입장치부(100)와, 터널(1) 벽면에는 물탱크 흡입장치부(100)에서 공급되는 찬 공기와 외부 공기에 의해 차량에서 배출되는 오염된 더운 공기가 대류현상에 의해 매연, 가스는 물탱크(2)로 흡입하고, 오염된 더운 공기는 상승하여 공기배출구(15)를 통해 굴뚝(13)으로 배출한다.The tunnel ventilator divides the bottom of the tunnel (1) and the water tank suction device (100) for supplying cold air of water continuously supplied to the water tank (2) on both sides of the tunnel (1) wall, and the tunnel (1) wall surface. Contaminated hot air discharged from the vehicle by the cold air supplied from the water tank suction device 100 and the outside air is soot by convection, gas is sucked into the water tank (2), and the contaminated hot air is Ascending and discharged to the chimney 13 through the air outlet (15).
상기 물탱크 흡입장치부(100)는 터널(1) 내부 바닥에 일정한 간격으로 크기를 달리한 다수개의 물탱크(2)를 매설한다.The water tank suction device 100 embeds a plurality of water tanks 2 having different sizes at regular intervals on the inner bottom of the tunnel 1.
상기와 같이 물탱크(2)의 크기를 달리하는 이유는 압력 차이를 달리하여 터널(1) 내부로 공급되는 찬 공기와 흡입되는 매연 및 가스를 원활하게 흡입할 수 있도록 하기 위함이다. The reason for varying the size of the water tank 2 as described above is to allow the cold air supplied into the tunnel 1 and the soot and the gas to be sucked to be smoothly sucked by varying the pressure.
또한, 매설된 물탱크(2) 사이 하부에는 물탱크(2)로 공급되는 물을 순환시키도록 물공급순환관(5)이 설치되며, 상기 다수개의 물탱크(2) 중 일측 단부에 위치하는 물탱크(2)는 물을 공급하는 물공급관(12)과 타측 단부에 위치하는 물탱크(2)에는 일렬로 배열된 물탱크(2)의 수위를 조절하기 위해 공급된 물을 배출하는 수위조절관(3)이 형성된다.In addition, a water supply circulation pipe 5 is installed at a lower portion between the buried water tanks 2 to circulate the water supplied to the water tank 2, and is located at one end of the plurality of water tanks 2. The water tank 2 is a water level control for discharging the water supplied to adjust the water level of the water tank (2) arranged in a line in the water supply pipe 12 for supplying water and the water tank (2) located at the other end The tube 3 is formed.
한편, 다수개의 물탱크(2) 중 중앙에 위치한 물탱크(2)의 크기가 제일 크고, 나머지 물탱크(2)는 크기를 상호 교차되게 배열하며, 상기 일렬로 배열된 물탱크(2)중 일측 단부에 위치한 물탱크(2)에는 물을 공급하는 물공급관(12)이 형성되고, 타측 단부에 위치한 물탱크(2)에는 수위조절관(3)이 형성되어 수위를 조절한다.Meanwhile, the largest size of the water tank (2) located in the center of the plurality of water tank (2), the remaining water tank (2) is arranged to cross the size of each other, among the water tank (2) arranged in a line The water tank 2 located at one end is formed with a water supply pipe 12 for supplying water, and the water tank 2 located at the other end is provided with a water level control tube 3 to adjust the water level.
또한, 물탱크(2)에 지속적으로 공급되는 물(17)은 터널(1)을 건설할 때 지하수가 흘러나오는 경우가 대부분이라 별도의 설비를 하지 않아도 지하수를 이용하여 물탱크(2) 내부로 물(17)을 쉽게 공급할 수 있다. In addition, the water (17) continuously supplied to the water tank (2) is the groundwater flows in most cases when the tunnel (1) is built, so it does not need to install a separate facility using the groundwater into the water tank (2) Water 17 can be easily supplied.
따라서 상기 물탱크(2)는 물공급관(12)을 통해 순환 공급되는 물(17)을 모든 물탱크(2)에 균일하게 1/3만 채우고, 초과 공급되는 물(17)은 외부로 배출하여 물탱크(2) 내부에 수위를 조절하며, 물탱크(2) 내부의 나머지 공간에는 외부 공기가 유입되어 찬 공기와 함께 터널(1) 내부로 순환 공급한다. Accordingly, the water tank 2 fills only 1/3 of the water 17 circulated and supplied through the water supply pipe 12 to all the water tanks 2, and discharges the excess water 17 to the outside. The water level is adjusted in the water tank (2), the outside space is introduced into the remaining space inside the water tank (2) and circulated supply with the cold air into the tunnel (1).
또한, 각각의 물탱크(2)에서 터널(1) 벽면으로는 찬 공기 배출 및 오염물질 흡입관(11)이 각각 설치되고, 상기 찬 공기 배출 및 오염물질 흡입관(11)의 끝단에는 찬 공기 배출 및 오염물질을 흡입할 수 있는 찬 공기 배출 및 매연, 가스 흡입구(4)가 설치된 구조로 이루어져 터널(1) 내부 바닥을 분할하여 터널(1) 벽면의 전ㆍ면 양측으로 각각 대향지게 형성된다.In addition, in each of the water tanks 2, the cold air discharge and the pollutant suction pipes 11 are respectively installed on the wall of the tunnel 1, and the cold air discharge and the end of the cold air discharge and the pollutant suction pipes 11 are respectively provided. Cold air discharge and soot that can inhale pollutants, and gas inlet (4) is provided in the structure is divided into the inner bottom of the tunnel (1) is formed facing both sides of the front and face of the tunnel (1).
따라서 상기 물탱크 흡입장치부(100)는 상ㆍ하행선을 기준으로 터널(1) 바닥 양측으로 일렬로 형성되는 게 바람직하나, 다른 실시 예로는 터널(1) 바닥 중앙에 물탱크(2)를 설치하고, 물탱크(2)의 양쪽으로 찬 공기 배출 및 오염물질 흡입관(11)을 설치하여 찬 공기를 배출할 수 있다.Therefore, the water tank suction device 100 is preferably formed in a row on both sides of the bottom of the tunnel 1 on the basis of the up and down lines, but in another embodiment, the water tank 2 is installed at the center of the bottom of the tunnel 1. In addition, cold air discharge and contaminant suction pipes 11 may be installed at both sides of the water tank 2 to discharge cold air.
한편, 물탱크 흡입장치부(200)를 구성하는 물탱크(2)의 내부로 외부 공기를 공급하기 위해 터널(1) 입구에는 외부공기 유입구(10)와, 상기 외부공기 유입구(10)와 연결되는 공기유입통로관(9)이 설치된다.On the other hand, in order to supply the outside air into the water tank (2) constituting the water tank suction device 200, the inlet of the tunnel (1) is connected to the external air inlet 10 and the external air inlet (10) The air inflow passage 9 is installed.
상기, 공기유입통로관(9)의 단부에 연결된 분기관(8)은 터널(1)의 전면과 배면 중앙에 위치한 물탱크(2)에 공기를 각각 공급하도록 분기되어 연결되고, 상기 분기관(8)이 연결된 물탱크(2)는 일렬로 배열된 다른 물탱크(2)에 공기를 공급할 수 있도록 물탱크(2)의 상부에 공기 유입관(20)이 연결되어 외부에서 공급되는 공기를 공급하면 찬 공기 배출 및 오염물질 흡입관(11)을 통해 찬 공기배출 및 매연, 가스 흡입구(4)로 배출하여 터널(1) 내부에 공급한다. The branch pipe 8 connected to the end of the air inflow passage 9 is branched to supply air to the water tank 2 located at the front and rear centers of the tunnel 1, respectively. 8) is connected to the water tank (2) is connected to the air inlet pipe 20 is connected to the top of the water tank (2) to supply air to the other water tank (2) arranged in a line to supply air supplied from the outside Cold air discharge and exhaust through the cold air discharge and contaminant intake pipe (11), discharge to the gas inlet (4) is supplied to the tunnel (1).
이때 물탱크(2)의 내부에는 1/3정도로 물이 채워진 상태에서 상부 빈공간으로 공급된 외부 공기와 물의 냉기가 결합되어 찬 공기배출 및 매연, 가스 흡입구(4)를 통해 공급한다.At this time, the inside of the water tank 2 is combined with the cold air of the outside air and water supplied to the upper empty space in a state filled with water about 1/3 to supply the cold air discharge and smoke, gas inlet (4).
한편, 터널(1) 내부 공기를 빠른 속도로 순환시키기 위해서는 터널(1) 벽면 양측에 공기 입구(21)를 더 형성한다. On the other hand, in order to circulate the air in the tunnel 1 at a high speed, the air inlet 21 is further formed on both sides of the wall of the tunnel 1.
따라서, 터널(1) 내부에 외부 공기를 직접 공급하기 위해서는 외부 공기 유입구(10)와 연결된 공기유입 통로관(9)을 통해서 물탱크(2) 내부로 외부 공기를 공급하는 분기관(8)에서 분기하여 도 2에서 도시한 바와 같이 터널(1)의 중앙 양측 벽면에 형성된 공기 입구(21)와 연결한다.Therefore, in order to supply external air directly into the tunnel 1, the branch pipe 8 supplying the external air into the water tank 2 through the air inlet passage pipe 9 connected to the external air inlet 10. Branching is connected to the air inlet 21 formed on the central both side walls of the tunnel (1) as shown in FIG.
그러면, 외부에서 유입되는 공기가 일부는 물탱크(2)로 공급되고 나머지 일부는 터널(1) 내부에 직접 공급할 수 있도록 다수개의 공기 입구(21)를 각각 형성한다. Then, a plurality of air inlets 21 are respectively formed so that some of the air introduced from the outside may be supplied to the water tank 2 and some of the air may be directly supplied into the tunnel 1.
즉, 터널(1) 한쪽 벽면에서 터널(1) 바닥 중앙에 매설된 메인 물탱크(2)를 기준으로 양측에 형성된 터널(1) 입구를 향해 다수개의 공기 입구(21)를 형성하고, 이중 다수개의 공기 입구(21) 중 하나는 중앙에 위치한 메인 물탱크(2)에 연결되고 다른 하나는 다른 물탱크(2)에 연결하면 외부에서 공급되는 공기중 일부는 공기 입구(21)를 통해 공급하고 일부는 물탱크(2) 내부로 공급하면 터널(1) 중앙에서 부터 외부공기를 공급하게된다.That is, a plurality of air inlets 21 are formed from one wall of the tunnel 1 toward the inlet of the tunnel 1 formed at both sides with respect to the main water tank 2 buried in the center of the bottom of the tunnel 1, and a plurality of One of the two air inlets 21 is connected to the central main water tank (2) and the other is connected to the other water tank (2) and some of the externally supplied air is supplied through the air inlet (21) Part of the water tank (2) to supply the outside air from the center of the tunnel (1).
그러면 내부에 있는 오염된 공기는 외부에서 공급되는 공기와 온도차가 발생하여 터널(1) 상부로 상승한다.Then, the contaminated air inside the temperature difference with the air supplied from the outside rises to the top of the tunnel (1).
한편, 공기 입구(21)에 공기를 공급하기 위해서는 터널 입구(1)에 별도의 공기 유입 통로관(9)을 설치하여 직접 연결할 수 있다. Meanwhile, in order to supply air to the air inlet 21, a separate air inlet passage 9 may be installed at the tunnel inlet 1 to directly connect the air inlet 21.
또한, 상승되는 오염된 공기를 외부로 배출하기 위해서는 찬 공기 배출 및 매연, 가스 흡입구(4)에 각각 연결되도록 일측은 분기 되고, 타측은 하나로 모인 공기배출연결관(7)이 터널(1) 벽면에 형성된 공기배출구(15)와 연결되고, 상기 공기배출구(15)는 공기배출통로관(14)이 설치되어 터널 (1)좌ㆍ우에 위치한 산악지대(18)로 돌출되게 형성된 굴뚝(13)으로 나쁜 공기를 배출한다.In addition, in order to discharge the contaminated air to the outside, one side is branched to be connected to the cold air discharge and the soot, and the gas inlet 4, respectively, and the other side of the air exhaust connection pipe 7 is gathered as one wall surface of the tunnel 1 Is connected to the air outlet 15 formed in the, the air outlet 15 is a chimney 13 formed to protrude into the mountain zone 18 located in the left and right of the tunnel (1) air discharge passage pipe 14 is installed Eject bad air.
또한, 상기 굴뚝(13)의 위치는 터널(1) 입구 양쪽에 설치하거나 지지형상이 낮은 쪽에 설치하는 게 바람직하다. In addition, the position of the chimney 13 is preferably installed at both sides of the inlet of the tunnel 1 or at a lower support shape.
한편, 굴뚝효과란 건물 내부와 외부공기 사이의 온도차에 따른 밀도차 즉 부력 차로 인하여 (대류현상) 건물의 수직공간을 통한 연기-공기의 유동을 말한다. On the other hand, the chimney effect refers to the flow of smoke-air through the vertical space of the building (convection) due to the difference in density, that is, the buoyancy difference between the temperature inside the building and the outside air.
정상상태에서 건물 내의 자연적인 공기 유동은 대부분 굴뚝효과이며 고층건물 화재시에는 이 굴뚝효과가 엘리베이터 슈트 (elevator chute), 린넨슈트, 배관슈트, 계단 등을 통해서 연기와 유독 가스를 폭 넓게 확산하게 된다.Under normal conditions, the natural air flow in a building is mostly the chimney effect, and in the event of a high-rise building, the chimney effect spreads smoke and toxic gases widely through elevator chute, linen chute, plumbing chute, and stairs. .
즉, 낮은 곳에 산업용 배기가스를 분출시 확산범위가 좁기 때문에 환경오염이 심각하지만 높은 곳에 분출시키면 확산범위가 넓어지게 되어 자연정화가 가능하게 되는 것을 말한다.In other words, since the diffusion range is narrow when the industrial exhaust gas is jetted in a low place, the environmental pollution is serious, but when the jet is discharged in a high place, the diffusion range is widened and natural purification is possible.
