Description

COMPLEX TYPE DUST COLLECTOR [0002]

More particularly, the present invention relates to an inertial dust collecting part attached to a running vehicle, and a combined dust collecting device collecting dust with an electric dust collecting part.

Each year the severity and risk of air pollution is emphasized. In recent years, there has been an increase in the awareness of fine dust particles, which are highly susceptible to cancer. This air pollution problem can not be an exception both inside and outside.

Most of the railway lines are underground in order to utilize space efficiently. Tunnels buried underground are closed spaces that are blocked from the outside. As the train travels, a lot of dust is scattered to the tunnel air due to the friction between the rail and the wheel, which causes serious air pollution of the tunnel.

The airborne dust in the tunnel air can penetrate into the inside of the passenger compartment through the openings of the outside air inlet of the air conditioner installed in the train, A filter or the like is installed in the outside air introduction port to remove the floating dust, but the dust collection efficiency is not high and a large amount of dust can be introduced into the inside. In addition, tunnel air flows in order to cool the inverter attached to the lower part of the electric train, dust floating in the air is deposited in the heat exchanger, which is the main cause of the inverter failure.

In order to solve such a problem, conventionally, a sweeper for cleaning the tunnels was periodically operated, or a large dust collector was installed in the tunnel to collect suspended dust. However, it is difficult to clean all the lines of the city railway efficiently because it is expensive because it is expensive, the number of vehicles is small, the dust is floated, and the suction method is slow and the operation speed is very slow and it is possible to work only at night time when the train is not operated. In addition, the dust collecting device installed in the tunnel is fixed in position, and the area of dust collecting effect is not wide. Therefore, in order to solve such a problem, it is necessary to always remove fine dust in the tunnel by attaching a dust collecting device to the moving train.

On the other hand, since the train must stop at each station, the traveling speed of the train is composed of patterns of acceleration, constant speed, deceleration and stop. It is necessary to provide a dust collecting device capable of exhibiting a constant dust collecting performance despite the running pattern of the electric motor vehicle, since the flow velocity of the lower portion of the electric motor vehicle induced by the running of the electric motor vehicle is not constant.

Hereinafter, a combined dust collector according to an embodiment of the present invention will be described with reference to the accompanying drawings.

1, a combined dust collecting apparatus 100 according to an embodiment of the present invention includes a body 110, a suction portion 120, an inertial dust collecting portion 130, an electric dust collecting portion 140, (150).

The body 110 is formed in a hollow shape opened to the front and rear sides. The outside air flows into the body 110 through the air inlet 111 of the body 110 and flows through the inside of the body 110 and out through the opposite air outlet 112.

The body 110 is fixed to the outside of the vehicle (not shown). At this time, the body 110 is arranged so that the direction in which the air inlet 111 and the air outlet 112 are opened is parallel to the running direction of the vehicle so that the outside air can naturally flow into the inside of the body 110 . In addition, considering that a lot of dust is generated from the floor surface when the vehicle is traveling, the body 110 is preferably mounted on the lower portion of the vehicle. However, the position where the body 110 is disposed is not limited thereto, and it may be disposed at various positions of the vehicle depending on the type of dust to be collected.

The air introduced into the body 110 through the air inlet 111 passes through the suction unit 120. The suction portion 120 is formed so as to have a reduced cross-sectional area from the air inlet 111 to the dust collecting portion 130, thereby increasing the speed of the air to be introduced. Accordingly, it is possible to mitigate the decrease in the flow velocity of the air flowing into the body 110 due to the flow resistance inside the body 110, compared to the case of the free flow.

The suction portion 120 may be formed so that the vertical cross-sectional area of the inner space with respect to the air inlet / outlet direction gradually decreases toward the inner side. For example, when the body 110 is attached to the lower portion of the vehicle, the lower portion of the body 110 on the side of the air inlet 111 may be formed to extend downward. Thereby, the flow of the outside air can be collected and sucked and accelerated. Thus, the suction unit 120 increases the flow rate and the flow rate of the air passing through the air inlet 111, thereby improving the dust collecting performance. However, if the dust collecting apparatus 100 is attached to the lower portion of the vehicle, it should not touch the floor. Therefore, the suction unit 120 may be designed in consideration of the increase in the size of the air inlet 111 .

The air having passed through the suction unit 120 moves to the inertial dust collecting unit 130. The inertial dust collecting unit 130 is configured to disturb the flow direction of the air naturally introduced into the body 110 by the running wind. This allows the dust contained in the air to trap the dust by preventing it from following the flow of the air.

Since the inertial dust collecting part 130 uses running wind of the train, it is preferable that the inertial dust collecting part 130 minimizes the flow resistance. The inertial dust collecting method applicable to the inertial dust collecting part 130 may be a louver method, a baffle method, a cyclone method, or the like.

First, the louver type inertial dust collecting unit according to an embodiment of the present invention guides the dust in the air to one side, and closes the flow path to collect dust.

2, the inertial dust collecting part 130 includes a plurality of blades 132 arranged at an angle with respect to an inflow direction of air introduced from the suction part 120, And a dust collecting box 133 through which the dust that has collided with the blade 132 flows along with the air flow.

The blade 132 is disposed so as to be inclined so as to face its upper surface with respect to the air inflow direction. The blades 132 are spaced apart from each other in the direction of the dust collecting container 133 from the suction portion 120. The blades 132 can also be arranged such that the upper surface of the blades 132 against which air collides is not covered by the blades 132 disposed immediately before when viewed from the suction portion 120. That is, each of the blades 132 may be arranged in series and higher than the lower end of the blade 132 located at the back of the blade 132 located at the front. The blade 132 is disposed until it contacts the upper inner wall of the body 110 where the inertial dust collecting part 130 is disposed. As described above, by preventing air from flowing between the blades 132 without colliding with the blades 132, the dust collecting efficiency of the inertial dust collecting unit 130 can be increased.

A portion of the dust contained in the air introduced into the inertial dust collecting part 130 (shown by the dotted line) does not follow the flow of air (shown by the arrow) and collides with the blade 132. Since the angle of the blade 132 is inclined at an acute angle to the inflow direction, the particles hitting the potential blade 132 move toward the rear blade 132 and collide again. This process is repeated until the dust finally enters the dust collecting container 133. On the other hand, the angle and the interval in which the blades 132 are disposed are not limited to those shown in the drawings, but may be appropriately selected in consideration of the size, weight, and flow speed of the dust to be collected.

The dust collecting box 133 is disposed behind the last blade 132 to position the inlet in the air inflow direction. When the air flows into the dust collecting box 133, the dust contained in the air loses its inertial force and accumulates on the inner wall. In order to prevent the collected dust from being re-scattered, it is preferable that the dust collecting container 133 is formed such that its cross-section has a hook shape.

Meanwhile, as shown in the drawing, a plurality of inertial dust collectors 130 may be arranged in parallel in a direction perpendicular to the inflow direction. Thus, dust collecting efficiency can be increased by simultaneously collecting dust in each inertial dust collecting part (130).

The baffle type inertial dust collecting unit according to the second embodiment of the present invention collects dust by forming a flow path so that air moves in a zigzag form.

3, the inertial dust collecting part 230 includes a plurality of subfilters 232 including two partition walls 233 facing each other and a blocking wall 234 connecting one end of the two partition walls 233 with each other ). The plurality of sub-filters 232 are arranged such that the openings facing the blocking walls 234 face each other. One of the two partition walls 233 is inserted into the opening of the other sub filter 232 to form a flow path F. [

The air introduced into the inertial dust collecting part 230 is blocked by the blocking wall 234, which is opposed to the flowing direction. The dust contained in the air collides with the blocking wall 234. At this time, the flow direction of the air is reversely reversed and flows between the partition walls 233 of the two facing sub-filters 232. Then, the air is once again obstructed by the blocking wall 234 of the sub-filter 232 on the suction portion 120 side. Further, the dust contained in the air collides with the blocking wall 234. As a result, the air flows in the same direction as the initial inflow direction and flows out of the inertial dust collecting part 230. [

In this way, while the air is passing through the inertial dust collecting part 230, the flow direction is switched several times in the opposite direction, and in the process, the dust having a relatively large inertia force can not follow the flow and collides with the blocking wall 234, (Not shown). Accordingly, the dust that has collided against the blocking wall 234 while the air is moving through the flow path F is gathered and enlarged to be separated from the blocking wall 234 and fall by gravity.

Dust that has collided against the blocking wall 234 due to inertia is collected by the dust collecting plate 235 and collected so that the dust accumulated in the dust collecting plate 235 is blocked by the scattering jig 236 and is not re-scattered by the flow.

The cross sectional shape, the arrangement direction, and the number of sub-filters 232 of the inertial dust collecting part 230 are not limited to the illustrated ones, but may have an angular cross-sectional shape as well as a round shape, And may be provided with fewer or greater numbers of sub-filters 232.

The cyclonic inertial dust collecting unit according to the third embodiment of the present invention has a cyclone structure and guides dust in the air outwardly.

4, the inertial dust collecting part 330 includes a cyclone body 331, a cyclone blade 332, and a cyclone dust collecting container 333. [

The cyclone body 331 has a streamlined shape in which the width on the side of the suction portion 120 is small and the width gradually increases toward the air outlet 112 side. This allows the air flow to be directed to the wall surface side of the body 110 along the outer wall surface of the cyclone body 331 without greatly increasing the flow resistance. The length, angle, and the like of the cyclone body 331 can be appropriately selected in consideration of the flow resistance caused by the cyclone body 331 and the dust collecting efficiency in accordance with the change in the flow velocity.

The cyclone vane 332 protrudes outward from the outer wall of the cyclone body 331. By means of the cyclone vane 332 formed so as to proceed in a helical manner with respect to the inflow direction, the air flow rotates with respect to the helical axis. The air flow traveling in the inflow direction by the cyclone vane 332 has a rotation component in a direction perpendicular to the inflow direction. Accordingly, as the flow velocity is somewhat slower and vertical component is formed, dust in the air may flow into the cyclone dust collecting container 333, which is recessed in the inner wall of the body 110, to lose inertia and be collected. That is, the dust in the air entering the suction unit 120 rotates along the cyclone vane 332, is guided to the wall surface by inertia, and is collected in the cyclone dust collector 333.

The length of the cyclone vane 332 projecting from the cyclone body 331 and the helix angle of the cyclone vane 332 do not significantly decrease the flow resistance so that the dust in the air can be collected at the cyclone dust collector 333 Can be appropriately selected to reduce the flow rate. Although not shown, it is preferable that a separate scattering prevention jaw is provided to prevent the dust collected in the cyclone dust collecting container 333 from being scattered again by the air flow.

As shown in FIG. 7, the inertial dust collectors 130, 230, and 330 in each of the above-described embodiments have an increased dust collecting efficiency as the inertia of dust increases, which is advantageous for dust collection under high-speed running conditions. Particularly, as the flow rate of the air passing through the air inlet 111 is faster, the inertial dust collecting units 130, 230, and 330 increase the dust collecting efficiency.

The inertial dust collecting part may employ various dust collecting methods not only in the above-described manner, but also other dust collecting methods that can block or induce flow by utilizing inertia of dust. Further, though not shown, the inertial dust collecting parts according to the respective embodiments may be arranged in a combined manner in series, thereby further increasing the dust collecting efficiency.

Referring again to FIG. 1, air passing through the inertial dust collecting unit 130 moves to the electric dust collecting unit 140. The electric dust collecting unit 140 collects dust by preventing the dust contained in the air from following the flow of the air by charging the dust in the air to form an electric field.

5A and 5B, the electric dust collection unit 140 of the present embodiment includes a discharge wire 141 or a discharge plate 144 and an electric dust collection plate 142. The discharge wire 141 or the discharge plate 144 is connected to a negative or positive electrode to generate negative ions or positive ions to charge dust in the air. The electrical dust collection plate 142 is connected to the ground.

A plurality of discharge plates 144 may be interposed between the adjacent electrical holding plates 142. The discharge plate 144 may include a plurality of discharge electrodes (not shown). On the other hand, the discharge wire 141 and the discharge plate 144 can be selectively used. A plurality of discharge electrodes may be provided by forming protrusions or cavities in the form of teeth or galls on the surface of the discharge plate 144.

The electric dust collecting unit 140 may include a plurality of discharge wires 141. The plurality of discharge wires 141 are placed perpendicular to the inflow direction, and each of the wires 141 may be disposed at a predetermined distance in the inflow direction. The number of the plurality of discharge wires 141, the arrangement direction and the interval are not limited to those shown in the drawings, but may be suitably selected in consideration of the dust collection efficiency for the air flow.

The discharge wire 141 or the discharge plate 144 is positioned in the center of two opposing electric dust collecting plates 142. The electric dust collection plate 142 may be disposed so as to face in a direction parallel to the inflow direction. An electric field is formed between the grounded electric dust collection plate 142 and the discharge wire 141. The charged dust moves to the dust collecting plate 142 and is collected.

On the other hand, a plurality of the electric dust collecting plates 142 may be arranged in parallel with respect to the inflow direction. At this time, the discharge wire 141 or the discharge plate 144 is disposed between two adjacent electric dust collecting plates 142.

6A and 6B, the electric dust collection unit 240 according to the second embodiment of the present invention includes a discharge wire 241 or a discharge plate 244, an electric dust collection plate 242, a ground plate 243, Respectively. The discharge wire 241 or the discharge plate 244 is connected to the positive electrode and the ground plate 243 is connected to the ground to generate positive ions to charge the dust in the air. The charged dust moves to the electric dust collecting plate 242. The electric dust collecting plate 242 is alternately connected to a ground or negative electrode and a positive electrode to form an electric field between the electric dust collecting plates 242. As a result, the cation-charged dust is collected in the electric dust collection plate 242 connected to the ground or negative electrode.

The electric dust collecting units 140 and 240 in the respective embodiments described above take time to move the dust charged and charged to the electric dust collecting plates 142 and 242 so that dust stays in the electric dust collecting units 140 and 240 As the time increases, the efficiency of collection increases. Therefore, as the air flow rate is slower as in FIG. 8, the dust collecting efficiency is increased, so that the electric dust collecting units 140 and 240 are advantageous for dust collection under low-speed running conditions.

On the other hand, in each of the above embodiments, dust can be collected in the electric dust collecting plates 142 and 242 where electric dust particles are charged in a single direction through the corona discharges. Particularly, the electric dust collection units 140 and 240 have a dust collection efficiency of 50% or more at a flow rate of 2.5 m / s or less.

As described above, by arranging the inertial dust collectors 130, 230, and 330 and the electric dust collectors 140 and 240 in combination in the respective embodiments in series, the present invention can be applied to all of the vehicles traveling at high speed or low speed The dust collecting efficiency is high. Referring to FIG. 9, the dust collecting efficiency according to the present invention includes inertial dust collectors 130, 230, and 330 having high dust collecting efficiencies in a high speed range and an electric dust collecting unit 140 , 240 are reinforced with each other, thereby exhibiting excellent performance over the entire speed range.

The arrangement of the inertial dust collectors 130, 230 and 330 and the electric dust collectors 140 and 240 is not limited to that described above, and the electric dust collectors 140 and 240 may be arranged in the order of the inertial dust collectors 130, 230 and 330 . The inertial dust collectors 130, 230 and 330 are disposed in front of the electric dust collectors 140 and 240 so that dust particles having relatively large particle diameters are removed by the inertial dust collectors 130, 230 and 330, It is preferable that the cleaning period of the electric dust collecting units 140 and 240 can be made longer by dust collecting by the dust collecting units 140 and 240 having a relatively small particle diameter.

Referring to FIG. 1 again, the air flow passing through the inertial dust collecting part 130 and the electric dust collecting part 140 may be discharged to the outside through the discharging part 150. The discharge unit 150 is configured to forcibly discharge the air inside the body 110 to the outside. For example, the discharge unit 150 may include an air blower (not shown) for blowing air inside the body 110 to the outside. Thus, air can be sucked into the inside of the body 110 even at a relatively low speed traveling condition, and the dust collecting efficiency can be maintained. Particularly, the discharge portion 150 can force air into the inside of the body 110 when the vehicle is stationary or when traveling at a low speed of 0.5 m / s or less.

In one embodiment, the speed pattern of the air flowing into the air inlet 111 with respect to the change in the running speed of the vehicle can be set in accordance with the time as shown in Fig. Since the dust collecting efficiency of the inertial dust collecting unit 130 is higher than the dust collecting efficiency of the electric dust collecting unit 140, the inertial dust collecting unit 130 collects dust mainly in the section A where the speed is relatively high. Since the dust collection efficiency of the electric dust collection unit 140 is higher than that of the inertial dust collection unit 130, the dust collecting unit 130 may be actively dusted in the electric dust collection unit 130 at a relatively low speed. On the other hand, in the overlapped portion of the section A and the section B, the dust collecting efficiency of the inertial dust collecting unit 130 and the electric dust collecting unit 140 is similar, so that the dust collecting by the respective dust collecting units can be reinforced. In the section C in which the vehicle speed is very low and the treatment flow rate is low, by maintaining the constant flow rate through the fan, the collection efficiency can be increased and the collection can be continued smoothly.

Meanwhile, although not shown, the above-described present invention may have a symmetrical structure. For example, when the vehicle travels in a reverse direction opposite to the forward direction, the air outlet 112 side becomes the air inlet, and each component may be arranged to be symmetrical about the fan 150. Thereby, it is possible to collect dust with respect to all running directions of the vehicle.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, have. Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. Therefore, it should be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
