Description

Subway two-way ultrafine dust removal module

The present invention relates to a subway two-way ultra-fine dust removal module, and more particularly, to a subway two-way ultra-fine dust removal module that can remove ultra-fine dust in an underground environment using the train wind generated when a train moves on a subway line. it's about

Fine dust is generated from the combustion process of fossil fuels, dust from roads, railways, etc., and has a particle diameter of 0.1 to 10 μm while floating in the air. Recently, interest in health risks is increasing to the extent that particulate matter smaller than 0.1 μm is classified as ultra-fine dust and managed separately. Fine dust causes an inflammatory reaction in the bronchi, causing or exacerbating asthma, chronic bronchitis, and airway obstruction. In addition, fine dust is recognized as an important risk factor for cardiovascular diseases such as myocardial infarction, stroke, heart rate abnormality, and sudden death. The risk of fine dust is closely related to the components of fine dust, and when it is caused by the combustion of fossil fuels, an important emission source of fine dust, the carbon component is surrounded by organic hydrocarbons, nitrates, metals, and sulfates. and these components play an important role in the toxicity of fine dust.

As described above, the emission source of fine dust is likely to be the combustion of fossil fuels and scattering from roads and railroads. As for dust scattering from railways, etc., there is no effective countermeasure technology so far. In addition, even in the case of a mobile emission source such as a vehicle, fine dust is primarily removed below the prescribed concentration by the fine dust reduction device attached to the vehicle when discharging, but the discharge occurs after some sealings such as subways and tunnels have been made. It was difficult to achieve proper ventilation in the city, and it was found to be more than 100 μg/m3, and this high concentration of fine dust is a big problem during the commuting hours from 7 to 9 and 18:00 to 20:00, which are used by tens of thousands of people.

The management of fine dust in the underground environment such as existing subway lines, subway stations and underground shopping malls has been focused on indoor environments such as subway stations, and the management of subway routes that directly generate fine dust such as subway movement is relatively insufficient. . In the case of the prior art for removing fine dust, various devices and technologies such as filter media, electrostatic precipitators, and cyclones have been developed to remove fine dust, but they have several problems when applied to subway lines and tunnels. For example, Korean Patent No. 1638065 uses a HEPA filter to remove fine dust from the air, but in this case, a pressure loss of at least 25 mmAq occurs, and the amount of air that can be processed per hour is low, so subway and tunnel trains are used. It is difficult to remove fine dust in the short time it passes. In addition, Korean Patent Application Laid-Open No. 2016-0054137 and Korean Patent Publication No. 2010-0107344 suggest a technology for removing fine dust using an electric dust collector or a cyclone, but both the electric dust collector and the cyclone are compared to filter-based dust collection facilities. Although the treatment flow rate is relatively fast, it has a problem of showing low treatment efficiency for fine dust of 2.5 μm or less. In the case of using the prior art described above, the speed of the subway moving train equipped with the dust collector must move at a slow speed of 30 km/h or less, and above all, a separate pump is installed to introduce external air into the inside of the moving train. It had to be done, and the configuration had the disadvantage of being complicated. In particular, when using a pump to introduce external air, as described above, it must be operated at a speed of 30 km/h or less to efficiently remove fine dust from the environment by subway, so that the concentration of fine dust is the highest. There is a problem in that it is difficult to use because it is connected to a moving carriage during commuting time, which has environmental and health implications.

Korean Patent No. 1638065 Korean Patent Publication No. 2016-0054137 Korean Patent Publication No. 2010-0107344 Korean Patent Publication No. 2012-0017995

<Example 1>

As shown in FIG. 1, the subway two-way ultrafine dust removal module according to the first embodiment of the present invention is provided inside the dust collecting train 1 connected to the subway, and the suction unit 10, the dust collecting unit 20 , the discharge unit 30 , the washing unit 40 , the power supply unit 50 and the control unit 60 are configured.

The suction unit 10 can be opened and closed while sucking air through the suction port 11 as a flow of air generated by the operation of the dust collecting train 1 . Here, the suction port 11 may be installed at two or more of the left and right sides, the lower part, and the upper part of the dust collecting train 1 to introduce the outside air by the train wind into the inside.

In this way, as the suction port 11 is installed at two or more places among the left and right sides, the lower part, and the upper part of the dust collecting train 1, the dust collecting train 1 can remove ultrafine dust from both directions of the connected subway.

Furthermore, the suction port 11 may be installed at two or more locations of the upper, lower, left, and right surfaces of the dust collecting train 1, and preferably installed on all four surfaces of the dust collecting train 1, so that the outside air caused by the train wind It is advantageous for influx of

And the suction port 11 is configured to be opened and closed by a damper or an opening on the surface of the suction port 11, and the opening and closing of the opening can be configured with a commercialized general technology, and detailed description thereof will be omitted in the present invention. .

In addition, the shape of the inlet 11 may be a circular or oval, or a prismatic with a predetermined angle, and in order to prevent the deposition of fine particles due to the configuration of the conduit having an angled edge, it is preferable to configure the pipe in a circular or oval shape. desirable.

And the suction port 11 may be configured to be installed at the rear of the train to which the dust collection train 1 is connected, 20 m or more, and specifically, it is preferably installed within the range of 20 m to 100 m or less.

As described above, limiting the installation position of the inlet 11 is that the dust collecting train 1 removes ultrafine dust contained in the subway environment by using the train wind as described above, and is located at the position where the train wind is the strongest. When measuring the location where the strongest train wind reflected from the upper ceiling, floor, and left and right walls of the subway line is generated, when 10 trains of 20 m in length are connected, vehicles No. 1 and No. 2 This is because the strongest train wind is generated at

In addition, the suction port 11 is configured to be able to open and close through the opening as described above, and protrude to the outside so that it can be opened facing the running direction of the dust collecting train 1 to maximize the inflow of external air. can At this time, the suction port 11 may be configured to extend to the outside by an electric motor (not shown).

As described above, the reason that the inlet 11 protrudes to the outside is to rapidly reduce the concentration of ultrafine dust in the subway environment.

Conversely, the suction port 11 may be parallel to the surface of the dust collecting train 1 or may be recessed inward from the surface of the dust collecting train 1 .

In this way, the suction port 11 and the depression into the inside are not to protrude to the outside during normal operation of the dust collection train 1, so that they do not interfere with the operation of the dust collection train 1, and the external protruding part is omitted. Accordingly, it is possible to minimize the running resistance of the dust collecting train 1 .

The suction unit 10 of the present invention is provided with a suction port conveying pipe 110 for conveying the air introduced from the suction port 11 to the dust collector 21 of the dust collecting unit 20 located at the rear end.

Here, the suction port conveying pipe 110 is preferably such that the air introduced from the suction port 11 is conveyed to the dust collector 21 of the dust collector 20 located at the rear end by the shortest distance, In order to minimize energy loss, it may be configured as an oblique line to have an inclination angle, and may be configured to gradually decrease in diameter. In this regard, the reduction in the diameter of the inlet transfer pipe 110 from the inlet 11 to the dust collector 21 is preferably in the range of 10% to 30%, and when it is 10% or less, the effect of increasing the flow rate of the introduced air is low and , if it is more than 30%, clogging of the pipeline may occur.

The dust collector 20 is located at the rear end of the inlet 11 , and is provided with a dust collector 21 for removing ultrafine dust contained in the air introduced through the inlet transfer pipe 110 .

As shown in FIG. 2 , the dust collector 21 includes a pre-filter 211 , an electric dust collection module 212 , and an ozone removal filter 213 to remove ultrafine dust contained in the air.

The pre-filter 211 pre-treats contaminants (eg, animal hair, lint, fine dust of 2.5 μm or more, etc.) having a larger particle size than ultra-fine dust contained in the air moving along the inlet transfer pipe 110. .

The electric dust collecting module 212 is located at the rear end of the pre-filter 211 , and discharge is generated by voltage application by the power supply unit 50 to collect ultra-fine dust contained in the air passing through the pre-filter 211 . At least one electrostatic precipitator is provided.

The electric dust collecting module 212 is, for example, to be provided with a first electric dust collector 212a, a second electric dust collector 212b and a third electric dust collector 212c in order to efficiently collect ultrafine dust contained in the air. can These first, second, and third electric dust collectors (212a, 212b, 212c) are installed to have a space apart from each other.

As such, the reason that the first, second, and third electric dust collectors 212a, 212b, and 212c have a separation space is to extend the movement distance of the air passing through the pre-filter 211 to efficiently remove ultrafine dust, This is to wash the first, second, and third electric dust collectors 212a, 212b, and 212c in a state in which the nozzle 42 of the cleaning unit 40 is positioned between the spaced spaces.

The ozone removal filter 213 is located at the rear end of the electric dust collection module 212, and is discharged together with the air from which ultrafine dust that has passed through the electric dust collection module 212 is removed due to the discharge of the electric dust collection module 212. Removes ozone moving toward the outlet 31 of the portion 30 .

Meanwhile, the dust collector 20 of the present invention may include not only the dust collector 21 but also a bag filter. In addition, the dust collector 21 can be replaced with a bag filter, but, as described above, the dust collector train 1 of the present invention operates at a speed of 60 km per hour or more, which is the speed of a commuter train, and uses ultra-fine dust in the subway environment. It was developed with an emphasis on removing , and it is preferable to apply the dust collector 21 , which is an electric dust collector, rather than a bag filter, in order to increase the amount of air purified per hour.

In addition, the dust collector 20 focuses on being used in a subway environment, and a magnetic filter may be additionally installed in the dust collector 21 to remove iron particles contained in a high concentration in the air.

The discharge unit 30 is located at the rear end of the dust collector 21 , and an outlet 31 is installed so that the air from which ultrafine dust has been removed by the dust collector 21 is discharged to the outside. And a fan 311 is installed inside the outlet 31 .

The fan 311 is installed inside the outlet 31 to induce the air (purified air) from which the ultrafine dust has been removed to be discharged to the outside while increasing the flow rate and flow rate of the air from which the ultrafine dust has been removed. Through this, the air from which ultrafine dust has been removed may be discharged to the outside with increased flow rate and flow rate.

The washing unit 40 is installed on one side of the dust collector 21, and a reservoir 41 and a nozzle 42 are provided to wash the dust collector 21 with a washing solution after collecting ultrafine dust contained in the air.

The storage tank 41 receives and stores the cleaning liquid required for cleaning the dust collector 21 from the outside. Here, the cleaning liquid is not limited as long as it is a fluid capable of removing (departing) the ultrafine dust adhered to the dust collector 21 from the dust collector 21 by discharge.

The nozzle 42 sprays the washing liquid stored in the storage tank 41 in the vertical and horizontal directions toward the dust collector 21 . To this end, the nozzle 42 includes a vertical nozzle 42a, a horizontal nozzle 42b, and an opening and closing port 42c, as shown in FIGS. 2 to 3 .

One end of the vertical nozzle 42a is directly connected to the storage tank 41 so that the washing liquid stored in the storage tank 41 flows, and the washing liquid that flows in and moves is vertically sprayed from the other end. And the vertical nozzle (42a) is located in the spaced space of the first, second, and third electrostatic precipitators (212a, 212b, 212c) to wash the first, second, and third electrostatic precipitators (212a, 212b, 212c) The cleaning solution can be sprayed radially.

The horizontal nozzle 42b is formed to extend from the vertical nozzle 42a in the horizontal direction with the vertical nozzle 42a as an axis, and sprays the washing liquid moving along the vertical nozzle 42a in the horizontal direction.

The opening/closing port 42c is provided at a portion connected to the vertical nozzle 42a and the horizontal nozzle 42b, and is opened and closed by the controller 60 to control the cleaning method of the dust collector 21 . And although not shown in the drawing, the opening and closing ports 42c are connected to the vertical nozzles 42a and the horizontal nozzles 42b as well as the reservoir 41 and the vertical nozzles 42a to control the inflow of the washing liquid. It would be desirable to be provided also in the part to be connected.

In addition, when the nozzle 42 divides the dust collector 21 into a lower portion and an upper portion in the horizontal direction (“air flow direction” in FIG. 2 ), the lower and upper portions of the dust collector 21 are washed in different ways.

Specifically, the vertical nozzle 42a sprays the washing liquid in the vertical direction so that the lower part of the dust collector 21 is washed, and the horizontal nozzle 42b sprays the washing liquid in the horizontal direction so that the upper part of the dust collector 21 is washed make it possible To this end, the vertical nozzle 42a is formed to extend in the vertical direction to a position where the lower part of the dust collector 21 can be washed, and the horizontal nozzle 42b includes the vertical nozzle 42a to wash the upper part. It would be preferable to extend in the horizontal direction with respect to the axis.

The power supply unit 50 supplies power to the first, second, and third electric dust collectors 212a, 212b, 212c so that voltage is applied to the first, second, and third electric dust collectors 212a, 212b, 212c of the electric dust collector module 212 . supply

As shown in FIG. 4 , the control unit 60 controls opening and closing of the suction port 11 , the operation of the dust collector 21 , the operation of the fan 311 , and washing of the dust collector 21 .

Among the control methods, for the operation of the dust collector 21, the control unit 60 controls the power supply unit 50 to supply power to the first, second, and third electric dust collectors 212a, 212b, and 212c, through which the first, 2, 3 A voltage is applied to the electrostatic precipitators 212a, 212b, and 212c. Through this, the ultrafine dust in the air that has passed through the pre-filter 211 may be collected by the discharge of the first, second, and third electric dust collectors 212a, 212b, and 212c.

In order to control the cleaning of the dust collector 21 , which is another control method, the control unit 60 adjusts the opening and closing of the opening/closing port 42c.

Specifically, the control unit 60 opens the opening and closing port 42c provided in the portion connected to the reservoir 41 and the vertical nozzle 42a, and to the portion connected to the vertical nozzle 42a and the horizontal nozzle 42b. The dust collector 21 is washed by opening the provided opening 42c so that the cleaning solution is sprayed in the vertical and horizontal directions. At this time, in the dust collector 21, both the lower part and the upper part divided in the horizontal direction are washed.

On the other hand, the control unit 60 opens the opening/closing port 42c provided in the portion connected to the reservoir 41 and the vertical nozzle 42a, but to the portion connected to the vertical nozzle 42a and the horizontal nozzle 42b. The dust collector 21 is washed by closing the provided opening and closing port 42c so that the cleaning solution is sprayed only in the vertical direction. At this time, in the dust collector 21, only the lower part divided in the horizontal direction is washed, and the washing process of the upper part is omitted.

In the first embodiment of the present invention, as described above, the dust collecting train 1 is included in the air using the train wind reflected from the upper, lower, left, and right wall surfaces and floors provided in the subway environment without using a separate pump, as described above. The configuration of the suction unit 10 is important because the purpose is to collect the ultrafine dust. In addition, in order to complete the dust collection process so that the ultrafine dust contained in the air can be removed only by the train wind flowing in the direction of the dust collecting train 1, without forcibly introducing external air with a pump, the dust collector ( 21) must flow only with the energy of the train wind, and above all, it is necessary to withstand the generation of differential pressure above a certain level due to the nature of the fine dust removal process, and secure enough air flow force to pass through the dust collector 21 .

To this end, in the first embodiment of the present invention, two or more suction ports 11 are installed in order to maximally absorb the train wind reflected from the left and right wall surfaces, the floor, and the upper surface of the underground passage, and the air introduced from the suction port 11 is removed. The suction port 11 and the dust collector 21 are connected in an oblique line through the suction port conveying pipe 110 that is transferred to the dust collector 21 so that the distance between the suction port 11 and the dust collector 21 is the shortest distance, and the suction port ( 11) to the dust collector 21 is gradually reduced in diameter, and is configured to compensate for the loss of the air flow rate step by step.

Here, each of the suction ports 11 installed in two or more places is combined into one through the air integration part 70 and is connected to the dust collector 21 .

As the flow rate and flow velocity of air are increased through the air integration unit 70, the dust collecting train 1 of the second embodiment of the present invention can remove fine dust from the air without operating a pump.

And the air integration unit 70 combines the air introduced through each inlet 11 to increase the flow rate and flow rate.

In addition, the air integration part 70 is an inlet of the air flowing into the air integration part 70 from the inlet 11 in order to prevent the incoming air from colliding with each other to reduce the flow rate, the air integration port 71 is mutually It is constructed so as not to face each other.
