These subways have the advantage of eliminating traffic congestion in the city center, but as they are built and operated in the depth of the underground, they are not easily ventilated with the outside, so they are composed of fine dust and harmful substances generated by the maintenance process of the subway and the operation of the train. As a result, users are not only uncomfortable, but also adversely affect their health.

Accordingly, in the subway, the ventilation system is applied to the outside of the subway by forcibly introducing outside air into the subway, but in this case, it is expensive to install between all the subway lines. In addition, energy savings are being used to reduce the operating time and frequency of the ventilation system installed in some parts.

However, due to the nature of the subway, trains move along rail tracks, and contaminants and contaminated air are spread throughout the subway due to the running wind of trains and trains. Of course, as the number and time of operation of the ventilation system is reduced, there is a problem that it is not practical.

In order to solve this problem, as shown in Figs. 1 to 3, a high pressure sprinkler or a dust collector is installed in a train moving along a rail track. The high pressure sprinkler is to spray the water into the subway space at a high pressure to adsorb dust to the injected water to purify the air, but the treated water mixed with dust and contaminants immediately goes to the sewer without going through a separate water purification process. As it flows into nearby rivers, it causes secondary pollution. In addition, water that has not been discharged into sewers accumulates in various places inside the subway, and builds up over time. There is a problem that the material is scattered again, and in the case of the train equipped with the dust collector, the dust collector, the hood train and the power supply train are large, and the equipment is enlarged and its price and operating cost are enormous. There was a problem that there is no.

The rail track air purifying apparatus of the present invention has a movement means 10 largely moving along the rail track 16 as shown in FIGS. 4 and 5, and is mounted on the movement means 10 to prevent fine dust and dirt. After removing the fine dust and pollutants contained in the external air by inhaling the external air containing the material, etc., the dust collector 20 for discharging the purified air to the outside again, and the inside of the dust collector 20 and the subway Compressed air supply device 40 for supplying compressed air to the space.

The moving means 10 is to operate the compressed air supply device 40, including the fixed type dust collector 20 that can not move by itself between the roads of the ground and the subway, the wheels 17 to drive the road of the ground ) Is formed and the wheels 11 are formed to be operable in all sections of the subway.

The wheel 11 is to allow the rail track air purifier of the present invention to be operated in all the subway, when the rail track air purifier is operated in the subway is extended from the moving means 10 by a hydraulic device The moving means 11 is moved along the rail track 16, and when the rail track air purifying device is operated on a general road, it is contracted so as not to interfere with the movement of the moving means 10.

The moving means 10 may be made of a train, but in this case, it is more preferable that a general freight vehicle in which the wheels 11 are formed is used as the volume of the device increases and constrains the movement.

The wheels 11 formed on the moving means 10 are axles 15 connecting the wheels 11 and the wheels 11 even in a standard track as well as a wide track between the rail tracks and a narrow gap between the rail tracks. Axle variable means for extending or contracting the axle 15 in accordance with the width of the rail track 16 is formed in the axle 15 connecting the wheel 11 so as to be able to operate without replacement. As referred to, the tread 14 of the wheel 11 abutting the upper portion of the rail track 16 is formed larger than the width of the rail track 16, and the inner and outer sides of the tread 14 A wide wheel 11 having an inner flange 12 and an outer flange 13 may be applied to surround a portion of an upper portion of the rail track 16.

As the general cargo vehicle in which the wheels 11 are formed as the moving means 10 to which the stationary dust collector 20 and the compressed air supply device 40 are mounted, it is easier to manufacture the moving means 10.

There is an advantage that the wheel 11 and the axle 15 do not need to be replaced.

6 and 7, the dust collector 20 mounted on the moving means 10 may suck the air inside the subway including fine dust and pollutants through the filter 27 provided therein. After removing the fine dust and contaminants from the air to discharge the purified air again to the outside to purify the air in the subway space, the air inlet 21 is formed to have a predetermined internal space to suck the outside air at the top And a plurality of cylindrical filters 27 for separating fine dust and contaminants from the air introduced from the air inlet 21 are stacked and provided therein, and the lower part is contaminated with fine dust by the filter 27. An air outlet 23 through which the clean air from which the material is removed is discharged, and a pollutant outlet 25 through which the fine dust separated from the air and the pollutant are discharged by the filter 27 is formed. The air outlet 23 is formed with a fan fan 24 for air blowing.

The dust collector 20 formed as described above generates negative pressure therein by the operation of the turbine fan 24 formed in the air outlet 23, whereby the air inside the subway is discharged through the air suction port 21. 20 is naturally introduced into the inside of the dust collector 20, and thus the air introduced into the dust collector 20 is, from the outside of the filter 27 to the inside of the filter 27, as shown by the arrow shown in bold solid line in FIG. The air is discharged through the air outlet 23 through the filter 27 and communicating with the internal space of the filter 27.

In the process in which the air introduced into the dust collector 20 is discharged to the outside through the filter 27, the fine dust and contaminants mixed in the air are blocked by the filter 27 and fall down, or the filter Only clean air stuck to the outer surface of the 27 and the fine dust and contaminants are removed is introduced into the inner space of the filter 27 and discharged through the air outlet 23.

The filter 27 is made of a synthetic resin material having a pore of 0.2 μm to 2 μm, and as shown in FIG. 8, the filter 27 has a cylindrical shape having wrinkles on its outer surface.

As the air gap of the filter 27 is made of 0.2 μm to 2 μm smaller than general dust, the filter 27 filters all fine dust as well as general dust, and the filtration area is formed as the outer surface is corrugated. Sudden increase in the dust collector 20, even if fine dust and contaminants are introduced can be expected sufficient filtration efficiency.

The filter 27 is any one of polyethylene (PE, Polyethylene), polypropylene (PP Polypropylene), glass fiber (Glass Piber), Nomax (Nomex), acrylic (Tcrylon), Teflon (Ryton) It is made of one or a mixture of them, as shown in Figure 8, the outer surface of the filter 27, the filter 27 during the movement of the filter 27 and insertion and withdrawal of the filter 27 ), And the metal mesh 27a may be formed to maintain the external shape of the filter 27.

By forming a negative pressure in the dust collector 20 to the outside air is discharged to the outside through the filter 27, the fan 24 receives power from the generator or battery of the moving means 10, or It is driven by the power of the engine.

As described above, the dust collector 20 collects fine dust and pollutants contained in the air inside the subway by using the filter 27 provided therein, and discharges only clean air into the subway. In order to purify the air inside, it is preferable that at least one or more air purification filters 27 are stacked and provided therein, and the filter 27 is inserted and inserted in the horizontal direction in consideration of ease of replacement and management. It is preferable to be provided in the horizontal direction inside the dust collector 20 to be drawn out.

An air inlet 21 through which air enters the dust collector 20 is formed on the dust collector 20, and an air outlet 23 through which air is discharged from the dust collector 20, and fine dust and pollutants are discharged. As the pollutant outlet 25 is formed in the lower part of the dust collector 20, the dust collector 20 has a downflow, that is, air flows from the top to the bottom in the process as air flows from the top to the bottom. Since the fine dust and contaminants contained free fall freely separated from the air and vortices do not occur inside the dust collector 20, the fine dust and contaminants separated from the air are scattered again, so the performance of the filter 27 is reduced. There is an advantage that does not degrade.

In addition, as the filter 27 is provided in the dust collector 20 in the horizontal direction, the filter 27 is taken out to the upper part of the dust collector 20, and the filter 27 is removed from the upper part of the dust collector 20. Compared to the inserting method, since no additional equipment or equipment is required, the filter 27 is easily replaced, thereby facilitating maintenance.

The dust collector 20 is formed with an air suction port 21 through which the outside air is sucked, and filters fine dust and contaminants from the air sucked into the dust collector 20 through the air suction port 21 therein. The filter 27 is provided, the air outlet 23 through which the air from which fine dust and pollutants have been removed by the filter 27 is discharged, and the fine dust and pollutants filtered by the filter 27 The external air introduced into the air suction port 21 by the suction force of the tub fan 24 provided in the air discharge port 23 of the dust collector 20 is formed of a pollutant discharge port 25 that is accumulated and discharged to the outside. Fine dust and contaminants are removed through the filter 27 and discharged through the air outlet 23.

In this process, high pressure compressed air is supplied from the compressed air supply device 40 to prevent deterioration of the performance of the filter 27 by adsorbing a large amount of fine dust and contaminants on the outside of the filter 27. It is supplied to the inside of).

The compressed air supplied from the compressed air supply device 40 is discharged into the internal space of the filter 27 through the compressed air injection nozzle 30 provided at one side of the internal space of the filter 27. Positive pressure is instantaneously generated in the internal space of the filter 27, and thus the compressed air inside the filter 27 is filtered from the internal space of the filter 27, as shown by the arrow shown by a small dotted line in FIG. Is discharged to the outside.

Accordingly, the fine dust and contaminants stuck to the outside of the filter 27 are separated from the filter 27 by the flow of compressed air discharged from the inside of the filter 27 to the outside of the dust collector 20. It will fall to the side.

Fine dust and pollutants that are separated from the filter 27 are accumulated on the pollutant outlet 25 formed at the lower part of the dust collector 20 due to the action of gravity and discharged to the outside.

The pollutant outlet 25 may be in direct communication with the outside, but in the process of removing the fine dust and pollutants by opening the pollutant outlet 25, the fine dust and pollutants are scattered to contaminate the surrounding air. It is preferable that the dust collecting container 26 is formed below the pollutant discharge port 25 to prevent the dust.

An air inlet 21 through which the outside air is sucked into the dust collector 20 is formed on the dust collector 20, and an air outlet 23 through which the external air is purified and discharged is formed below the dust collector 20. As a result, the life of the filter 27 is extended as the fine dust and contaminants fall freely downward in the course of air circulation.

The compressed air supply device 40 mounted to the moving means 10 together with the dust collector 20 supplies compressed air of high pressure to the filter 27 in which fine dust and contaminants are adsorbed to the outside. By removing the fine dust and contaminants adsorbed on the outside of the filter 27, the compressed air supply device 40 does not reduce the life and purification performance of the filter 27.

The compressed air supply device 40 is when the flow rate of the air circulated in the filter 27 or the dust collector 20 is a predetermined amount or less, that is, a large amount of fine dust and contaminants adsorbed outside the filter 27. Only when the air is supplied, the compressed air is supplied into the filter 27.

The compressed air supply device 40 is further provided with injection means 41 for injecting compressed air into the subway.

The injection means 41 injects high pressure compressed air from the compressed air supply device 40, and dust and pollutants accumulated in the subway are scattered by the compressed air injected by the injection means 41. As the fine dust and contaminants scattered are introduced into the dust collector 20 and collected, the air purification performance of the dust collector 20 is improved.

The injection means 41 may be formed to face a certain direction and a certain point, such as the top or bottom, it may be formed at the end of the conduit free deformation to face a specific direction and a specific point.
