Abstract
Description
The present invention relates to an apparatus and method for removing harmful substances in a tunnel that rapidly removes harmful substances such as noxious gas and dust generated due to fire when a fire occurs in a tunnel.
Generally, a tunnel is a structure that penetrates a mountain, constructs a road and a railroad track, and allows a predetermined moving object including a vehicle and a train to pass through.
Such a tunnel is usually formed by inserting a mountain, installing a waterproof mat on the inner wall surface, and forming a semicircular or semi-circular shape by pouring concrete or the like. In the tunnel, A railroad track, and the like.
The tunnel has a short section of only a few tens of meters, but also a long section of several hundred meters or several kilometers.
If a fire occurs in a tunnel when a predetermined moving object passes through the tunnel, there is a risk that it may lead to a large personal injury.
That is, various kinds of accidents such as a collision or a collision accident may occur within the tunnel while the moving object moves, and a fire may occur due to collision or collision. When a fire occurs in a tunnel, harmful substances such as noxious gas and dust are rapidly generated. Due to the nature of the internal structure of the tunnel, the harmful substances generated by the fire are easily trapped inside the tunnel It can not be discharged and remains in the inside of the tunnel.
When a fire occurs in a tunnel, other moving objects, which normally travel in the tunnel, may no longer be able to travel. Therefore, in order to evacuate the fire, the passengers of the moving object usually depart from the moving object I walk out of the tunnel.
However, in the case of a fire occurring inside a long tunnel having a length of several hundred meters or several kilometers, it takes a considerable time until the occupants of the moving object walk out of the tunnel, It is very likely to be damaged. Especially, there is a high possibility of serious damage to passengers when there are elderly or young children.
Therefore, when a fire occurs inside a tunnel, it is necessary to suppress the fire quickly, to quickly remove harmful substances such as harmful gas and dust generated by the fire, and to prevent the spread of harmful substances. have.
As a disaster prevention system for suppressing a fire when a fire occurs inside a tunnel, Korean Registered Utility Model No. 20-0334297 (prior art 1) is known.
According to the
However, in the
In Korean Patent No. 10-1565596 (Prior Art 2), there is provided an evacuation outlet provided adjacent to a sidewall provided at one side of a tunnel, and an evacuation outlet disposed adjacent to the evacuation exit to blow noxious gas to the other side of the tunnel. An exhaust duct installed in a ceiling of the other side of the tunnel and extending in the longitudinal direction of the tunnel and extending outside the tunnel; and an exhaust duct installed in the exhaust duct and generated inside the tunnel An evacuation frame disposed between the air blowing fan and the air blowing fan and configured to protrude / retreat along a main body frame installed on an inner wall of the tunnel and installed with an acceleration fan, And an acceleration motor connected to the acceleration fan, A power supply part for supplying power to the acceleration motor when the protruding and retracting frame protrudes into the tunnel and a diffusion preventing part including a protruding and retracting frame for protruding and retracting the protruding and retracting frame from the body frame, In the event of a fire, the identification of harmful substances and the spread of flames are prevented.
However, in the
SUMMARY OF THE INVENTION The present invention provides an apparatus and method for removing harmful substances in a tunnel that rapidly removes harmful substances such as noxious gas and dust due to the occurrence of a fire when a fire occurs in a tunnel .
A problem to be solved by the present invention is that harmful substances such as dust caused by fire generated in a tunnel are quickly pushed to the road surface of the tunnel and harmful substances such as harmful gas are discharged to the entrance and exit of the tunnel at a high speed An apparatus and method for removing harmful substances in a tunnel are provided.
Further, the present invention is not limited to the above-mentioned problems, and other problems not mentioned can be clearly understood from the following description by those skilled in the art to which the present invention belongs .
An apparatus for removing harmful substances in a tunnel according to the present invention includes a plurality of water supply pipes installed in a tunnel in a transverse direction with respect to a running direction of a moving body and having a plurality of water injection nozzles for spraying water to remove toxic substances A water supply pump for supplying water to the plurality of water supply pipes; a plurality of water supply valves provided between the plurality of water supply pipes and the water supply pump for supplying or blocking the water; A plurality of water supply valves other than the water supply valve at a position corresponding to a fire occurrence position are determined as water supply valves for removing harmful substances and the harmful substances are removed based on the fire occurrence position The water supply valves are sequentially opened from the fire occurrence position to the entrance and exit direction of the tunnel at unit time intervals And a control unit for repeatedly closing the room and controlling the removal of harmful substances in the tunnel.
The control unit divides a plurality of water supply valves for removing the harmful substances into a plurality of groups and sets a plurality of water supply valves of each group at a unit time interval from the fire generation position to the entrance and exit direction of the tunnel It is possible to control the removal of harmful substances in the tunnel by repeating the sequential opening and closing.
The apparatus for removing harmful substances in a tunnel according to the present invention may further include a plurality of water injection nozzle angle adjusting units capable of adjusting the injection angles of the plurality of water injection nozzles, The control unit controls the injection angle of the water supply valve for removing the harmful substances from the fire occurrence position to the entrance and exit direction of the tunnel and then controls the water supply valves from the fire occurrence position to the entrance and exit of the tunnel, It is possible to control the removal of the harmful substances in the tunnel by repeating the opening and closing sequentially at the unit time intervals in the exit direction.
The method for removing harmful substances in a tunnel according to the present invention includes the steps of: a control unit determining a fire occurrence position by an output signal of a fire detection unit; The method comprising the steps of: determining a plurality of water injection nozzles for spraying water for removing harmful substances from the spray nozzles; and controlling a plurality of water supply valves corresponding to a plurality of water injection nozzles for spraying the water, And sequentially repeating opening and closing at a time interval from the fire occurrence position toward the entrance and exit direction of the tunnel.
The control unit drives the water supply pump and sequentially opens and closes a plurality of water supply valves corresponding to a plurality of water injection nozzles for spraying the water at unit time intervals from the fire occurrence position toward the entrance and exit direction of the tunnel Wherein the step of repeating the steps of forming the plurality of water injection nozzles includes the steps of forming a plurality of groups by sequentially arranging a plurality of water supply valves corresponding to the plurality of water injection nozzles to spray the water, And repeating opening and closing of the plurality of water supply valves sequentially from the fire occurrence position to the entrance and exit direction of the tunnel at a unit time interval.
