Description

Micro dust removing device

Technical Field

The present invention relates to a dust removing device, and more particularly to a dust removing device including: the canvas is installed at a predetermined height from the ground by a balloon at a city center, and then water is supplied to the canvas to flow the water, while floating dust particles are adsorbed to the canvas and flow to the lower part together with the water, thereby directly removing the dust particles, or water is supplied to the canvas surface, the structure surface or the building surface provided on the building surface to directly remove the dust particles.

Background

The fact that a lot of ozone is generated on the coast and thus there has been a nursing home for tuberculosis patients on the coast in the past, but the high humidity in the air is not good for the health of the lungs, has proved to be followed by not only higher humidity than inland but also frequent fogging, and thus gradually disappeared from the coast in the nursing home for tuberculosis patients.

The mist is generated in the case where there is a certain temperature difference between moisture particles evaporated from the ground surface and the water surface and the atmosphere, and the more media (such as fine dust) that can be combined with the moisture particles in the atmosphere, the more easily the mist is formed.

As production facilities causing air pollution are gradually increased, the amount of fine dust is also gradually increased, and the concentration of fine dust in the atmosphere is not so high from now on to decades, so that mist is mainly formed in spring, but mist containing a large amount of fine dust is not known from when and often occurs in winter regardless of seasons under the name of smoke (Smog).

In many cities, the concentration of the dust particles is very high at ordinary times, particularly in winter, the precipitation is low, heating equipment is started, and the concentration of the dust particles cannot be measured.

However, even if the concentration of atmospheric pollution is increasing, people are to persist in life in an environment where breathing is difficult, and thus there is an increasing awareness of the situation in which there is a possibility that they are becoming immersed in a deepened disease.

Further, although the concentration of atmospheric pollution in countries around the world is not serious, the concentration of fine dust is becoming higher, and therefore the concentration of fine dust is often so high that it is difficult to breathe.

The pure water in the air is slightly higher, which is not good for lung health, but people now live in smoke containing a large amount of moisture particles and dust harmful to human body, so that measures for directly removing dust floating in the atmosphere are urgently needed for people's health.

The world countries have signed the "paris climate convention" in 2015 because of the serious impact on global environmental perception on rapidly increasing air pollution, but the convention is not completely mandatory and is not completely approved for the purpose of improving the industrial competitiveness of the countries.

Now, the world countries consider the atmospheric pollution of the country not very serious, but are gradually aware that the emission standards of all the equipments causing the atmospheric pollution should be more strengthened, but are not aware of the fact that the atmospheric environment cannot be improved if the large amount of fine dusts moving in the air floating is not actively removed.

The more serious the air pollution, the more the competitive products are produced, and the health of people is threatened greatly.

However, with the immediate start of action, people have to live in heavily polluted environments for decades with the atmospheric environment improved to some extent.

Further, since the concentration of atmospheric pollution in countries around the world is increasing, it is needless to say that the emission standards of atmospheric pollution should be more enhanced than ever, and the fact that the atmospheric environment can be improved by actively removing fine dust floating in the atmosphere should be also taken into account.

In addition, not only various kinds of fine dusts, which are the main causes of global warming, but also water-soluble toxic gases are actively removed to restore the same global environment and ecosystem as before.

Thus, a patent is filed which is capable of removing not only various fine dusts floating and moving in the atmosphere but also water-soluble toxic gases and powders (yellow sand) economically and most effectively.

Further, compared with plant wastewater, if plant wastewater purified according to discharge standards flows into rivers without wastewater treatment plants, the rivers are naturally polluted, so that it is astonishing to see seriously polluted rivers in this industrialized era, and there is no active and practical measure such as planning of construction of wastewater treatment plants for improving river water quality, and if the discharge standards of wastewater are further strengthened, it is only a widely expecting that the problem of river pollution can be automatically solved.

The concentration of airborne dust is increasing due to rapid industrialization, but the ability to be eliminated naturally has exceeded the limit long ago.

In particular, it is considered that fine dust disappears together with rainwater in summer, but fine dust other than that which disappears together with rainwater or that which is naturally removed by forests accumulates on the ground surface, and the fine dust accumulated on the ground surface repeatedly rises and falls by the convection phenomenon of air and re-enters the atmosphere, thereby becoming a source of another fine dust.

It is mistaken that the dust particles can disappear from the field of view by blowing through the wind, but only the concentration of the dust particles moving in each area by the balloon effect is increased, the total concentration of the dust particles in the atmosphere is not changed, and the basic concentration of the dust particles in all the areas is gradually increased.

Although the atmospheric environment can be improved to a certain extent by further strengthening the emission standards of factories and automobiles as air pollution sources, the forest which can naturally remove fine dust is absolutely lacking due to rapid industrialization, and the amount of fine dust generated is larger than the amount of fine dust to be removed, so that the atmospheric environment cannot be improved finally if floating fine dust is not removed at one time

Therefore, for example, in order to improve the river water quality, even if the wastewater discharge standard of the factory is strengthened, there is a possibility that the factory wastewater exceeds the standard, and therefore, a wastewater treatment plant is provided to collect all the factory wastewater exceeding the standard for one-time purification, and similarly, a fine dust treatment facility such as a wastewater treatment plant is provided in the atmosphere to collect all the fine dust floating and moving in the atmosphere for one-time removal, so that the fine dust can be actively and directly removed, and the problem of the air pollution can be fundamentally solved.

Many air cleaners are also provided to directly remove a large amount of fine dusts floating in the atmosphere, but the fine dusts do not have a passage unlike a flowing river but are widely diffused with the wind, and the distribution range of the fine dusts is very wide, so that there are problems of installation costs and environmental pollution derived during the operation, so that it is not a practical measure.

Artificial rainfall is theoretically possible, but the surrounding atmosphere has a limited moisture content and is therefore not continuously available, and a method should be sought that can remove directly and effectively the airborne fine dust at the lowest cost.

Conventionally, flying insects cannot be killed by an insecticide harmful to the human body in a canteen, and therefore, long paper coated with a viscous liquid is hung on the ceiling of the canteen to kill the flying insects.

Accordingly, when a viscous liquid is applied to the surface of a structure, fine dust floating in the air is automatically attached to the surface of the structure and removed, like flying insects, but the adsorption force of the viscous liquid gradually decreases due to evaporation, and thus there is a problem that the adsorption force needs to be continuously maintained.

In order to kill the small flying insects with vitality, a viscous liquid is coated on the surface of the structure, but in order to remove the dead tiny dust, the tiny dust can be fully removed by using water with viscosity lower than that of the viscous liquid.

The fine dust floating and moving in the atmosphere directly passes through the dry surface of the structure along with the flow of the air, and if the surface of the structure flows water all the way, the flowing water acts as an artificial catalyst to promote the fine dust floating and moving in the atmosphere to contact and be adsorbed on the surface of the structure, so that not only various kinds of fine dust can be removed, but also water-soluble harmful gas and powder (such as yellow sand) can be directly removed.

Therefore, if the structure surface is always in a wet state from the time when the minimum predetermined reference wind is blown up to the time when the maximum predetermined reference or more strong wind is blown up, the fine dust floating and moving from the periphery of each area along with the air flow can be adsorbed from the initial stage as if the fish school in the water is automatically trapped in the net while passing through the fixed net, and therefore, the fine dust can be removed directly and positively.

In addition, since the temperature of water flowing down from the surface of the structure is relatively lower than the temperature of the moisture particles floating in the atmosphere and the water and the moisture have a property of being aggregated with each other, the water flowing down from the surface of the structure serves as an artificial catalyst to promote contact and adsorb the water particles floating in the atmosphere.

Therefore, the mist and the smoke pass through the wall surface while leaving a slight wet trace on the dry wall surface, but the wall surface which is always wet by water can easily contact and adsorb the moisture particles contained in the mist and the smoke, so that the mist and the smoke can be gradually cleared.

Now, a large amount of fine dust is already present in the atmosphere, and the amount of fine dust generated as compared with the amount of fine dust removed is gradually increasing, and thus the easy fog and mist generating conditions are gradually increasing.

The mist and fog forming place means a place where a large amount of fine dusts are already concentrated to some extent, and is therefore a good opportunity to be able to clarify the large amount of fine dusts.

Even if the surface of the structure is constantly wetted with the downflowing water, if the flow of air is stopped, the effect of removing mist and mist other than the periphery is very small. However, the mist and the mist always move, and therefore if the surface of the structure is always wetted with water, the mist is adsorbed while contacting with the moisture particles contained in the mist as if the fish school is automatically trapped in the net while passing through the stationary net, so that the mist and the mist gradually disappear, and the fine dust and the moisture particles contained in the mist are automatically removed together.

The temperature rise as the sun rises causes the mist and moisture particles of the smoke in the atmosphere to evaporate, so that even if they disappear from view, if there is no wind, the dust remains in the atmosphere obscuring the view. However, since wind blows at all times and fine dust in the atmosphere moves, if the surface of the structure is constantly wetted with water, a large amount of fine dust can be actively removed before the fine dust is completely diffused.

Accordingly, since the means for wetting the surface of the structure with water at all times is provided in each of the areas having a high concentration of fine dust from the initial stage when the fine dust flows into the atmosphere and floats and moves, and the surface of the structure is always wetted by the strong wind from the wind blowing up to the minimum predetermined reference to the wind blowing up to the maximum predetermined reference or more, not only the fine dust floating and moving in the atmosphere but also the fine dust contained in the mist and the moisture particles are directly removed while traveling with the wind, the atmospheric environment can be actively improved.

In addition, every time the moisture particles in the atmosphere exceed the proper level, the moisture particles are adsorbed and removed, so that the generation of the causes of fog and smog can be prevented to a certain extent.

However, since the safety of the apparatus for removing fine dust is threatened when strong wind of a predetermined standard or more is blown in the atmosphere, the fine dust removing apparatus should be withdrawn when strong wind of a predetermined standard or more is present.

Finally, it may be mistaken that the dust particles can disappear from the field of view by blowing through the wind, but only the concentration of the dust particles moving in the respective areas by the balloon effect is increased, while the total amount of the concentration of the dust particles in the atmosphere is not changed, and the amount generated compared to the amount of dust particle elimination is gradually increasing, so that the basic concentration of the dust particles in the atmosphere is also gradually increasing.

Further, although the concentration of the fine dust is low in summer season with a large amount of precipitation, the fine dust accumulated on the ground surface gradually returns to the atmosphere, and thus the concentration of the fine dust rapidly increases from the season with a small amount of precipitation.

It is possible to consider a method of removing fine dusts from the surface of a structure which is always wetted with water and a method of an air cleaner which sprays water with an electric pump. However, as in the fishing method, there is a difference in the collection method of the fine dust, such as a method of automatically trapping the fish population with a fixed net, and a method of forcibly pumping the fish population together with the seawater by a pump.

There is a fundamental difference in the system in collecting the fine dust as the former catches the gills of the fish with a large mesh, while the latter catches the fish not with a fine mesh but by forcibly pumping the fish population together with the seawater.

In addition, the former method is to actively contact the fine dust, while the latter method is to passively contact the fine dust by spraying water with a powerful pump, and thus there is a fundamental difference in the method of contacting the fine dust.

In addition, as a method of catching fish with a fishing net, in which a fish group in water passes through a fixed net and gills are automatically caught on the fishing net or a method of catching fish with a fine net and a method of catching fish with a fishing net pulled by a ship also exist, there are various methods for removing fine dust, and thus there are fundamental differences.

A first embodiment of a fine dust removing apparatus for directly removing fine dust floating in the atmosphere by suspending canvas on a balloon in the atmosphere, comprising: a balloon 1a on which canvas is hung and fixed to the ground by a rope; canvas 1b for collecting floating fine dust by water flowing on the surface; an automatic water distribution means 1c which is composed of an inlet passage 1c-1, an inner passage 1c-2, an outer passage 1c-3, a swing lever 1c-4, and a packing member 1c-5, and automatically switches the direction of water flow in a direction opposite to the direction in which the canvas is inclined, wherein the inlet passage 1c-1 supplies water to the automatic water distribution means; the inner passage 1c-2 is opened from the inside of the automatic water distributor to the lower end, the outer passage 1c-3 is discharged from the automatic water distributor to the external pipe 1g, the swing link 1c-4 is moved in the direction in which the canvas is inclined, and the packing member 1c-5 is attached to the end of the swing link 1c-4 and blocks one of the two water passages 1c-2 or 1 c-2'; a rope 1d connecting the balloon 1a and the ground 1 j; a line 1e for supplying water from a pump 1i above the ground to the automatic water dispenser 1 c; a water supporting module 1f which is transversely arranged in the surface of the canvas 1b at proper height intervals to delay the downward flow of water and prevent the water from being gathered to the center in order to prevent the water flowing down from the surface of the canvas 1b from being gathered to the center; a pipe 1g supplying water from the uppermost portion of the canvas 1b to both ends; a rope 1h for laterally fixing the ropes 1d, 1 d'; a pump 1i located on the ground and supplying water to the upper end of the canvas 1 b; a hole 1k for discharging water from a pipe 1g provided at the uppermost end of the canvas 1 b; the rope 1m fixes the balloon 1a and the canvas 1b to prevent excessive inclination by wind.

The dust removing apparatus described above has a plurality of

balloons

1a, 1a ' hung on the ground surface with

ropes

1d, 1d ', and a canvas 1b having an appropriate height and width is stretched and hung on the

balloons

1a, 1a ', and the surface of the canvas 1b is constantly wetted with water, thereby directly removing dust floating in the atmosphere.

Water pumped up from a pump 1i provided on the ground surface passes through the pipe 1e and enters the inside of the automatic water distributor 1c through an inlet 1c-1 of the automatic water distributor 1c provided at the uppermost end of the canvas 1 b.

The swing rod 1c-4 arranged in the water automatic distributor 1c inclined in the same direction as the canvas 1b along with the wind direction is inclined to the downwind direction, and the filling member 1c-5 attached to the tail end of the swing rod 1c-4 blocks the downwind side water internal channel 1c-2 or 1c-2' and simultaneously opens the upwind side water internal channel 1c-2 or 1c-2', so that the water is transmitted to the upwind side external channel 1c-3 or 1c-3 '.

The water passing through the upwind-side external passages 1c-3 or 1c-3 'is injected to the uppermost end of the canvas 1b through upwind-

side tubes

1g or 1g' connected to both ends of the uppermost end of the canvas 1b and a plurality of

holes

1k or 1k 'perforated downward in the

tubes

1g or 1g' toward the canvas 1b, thereby continuously flowing downward along the upwind-side surface of the canvas 1b, so that the upwind-side surface of the canvas 1b is constantly wetted by the water, thereby removing fine dusts.

The rope 1d is a rope for fixing the canvas 1b suspended from the balloon 1a to the ground surface and also for fixing the canvas 1b in the longitudinal direction, and the rope 1h is a rope for fixing the canvas 1b and the rope 1d in the lateral direction.

Since the canvas 1b suspended on the balloon has a convex shape in both the longitudinal and lateral directions in the center of the canvas 1b, as in the case of the sailboat being blown by wind, the

water receiving modules

1f and 1f' are provided on the surface of the canvas 1b so that the water flowing down along the surface of the canvas 1b is not collected in the center, and the water is made to flow down as widely spread as possible in the horizontal direction.

The

tubes

1g and 1g ' are tubes provided with the uppermost end of the canvas 1b in the middle thereof and disposed on both sides thereof, and water is delivered to both ends along the uppermost end of the canvas 1b by the water automatic distributor 1c located at the uppermost end, and a plurality of

holes

1k and 1k ' are provided in the

tubes

1g and 1g ' to perforate the canvas downward.

The rope 1m is a rope for preventing the canvas 1b from being inclined excessively downwind and being fixed finely.

Two

small pipes

1g, 1g ' connected to an automatic water distributor 1c located at the uppermost portion of the canvas 1b, and a plurality of

holes

1k, 1k ' perforated downward toward the canvas side in the

pipes

1g, 1g '.

A long water supporting block 1f surrounding the canvas is attached to the surface of the canvas 1b, so that water and fine dust flowing on the surface are collected and flow down slowly and widely spread transversely as much as possible while being collected in another water tank.

When canvas is hung on a balloon in the atmosphere, it may come into contact with not only surrounding flying objects but also buildings and electric wires, and this may cause fatal safety accidents and also cause a beautiful disturbance of the surrounding environment, and thus it is necessary to satisfy extremely limited and severe conditions.

However, since there is an urgent need to solve the problem of air pollution, it is considered that the air environment can be improved and the air conditioner can be installed in a place where a safety accident cannot be caused under less severe conditions.

The range in which fine dusts directly affect the living environment of human beings is about 10m or less from the ground, and the less the fine dusts are blown, the more the weight is increased as the scale of the wet canvas hung on the balloon is increased, and thus the possibility of safety accidents occurring during the management is gradually increased, and thus the scale of the canvas is not made as large as possible.

When a canvas having a dry surface and an appropriate height and width is hung on a plurality of balloons and is deployed in the atmosphere, fine dust floating around the canvas passes directly through the canvas, whereas when the surface of the canvas is constantly wetted with water, water running from the canvas surface acts as an artificial catalyst and adsorbs the fine dust while coming into contact with the fine dust floating, and therefore, not only various kinds of fine dust but also yellow sand such as dust and water-soluble toxic gas can be directly removed.

Therefore, since the fine dust floating and moving in each region having a high fine dust concentration is directly removed by being adsorbed while contacting the surface of the structure, it is possible to actively solve the serious air pollution in each region.

Before a strong wind of a predetermined standard or more, the canvas hung on the balloon should be collected and stored in a safe place.

The fog and the smoke are formed in the state that the air flow is stopped, but wind always rises and thus moves, so that the fog and the moisture particles contained in the smoke are adsorbed and removed while contacting with the canvas surface which is always wetted while the air starts to move, and thus the fog and the smoke disappear, and the fine dust contained in the smoke is automatically removed together with the moisture particles.

The canvas hung on the balloon is inclined downwind, so that water sprayed out from the uppermost end of the canvas can directly fall down towards the downwind side. Therefore, it is preferable to provide an automatic water distributor for automatically switching the water flow direction to the leeward side of the canvas while tilting the canvas so that the water discharged from the uppermost end of the canvas flows down along the leeward side surface of the canvas.

The automatic water distributor is inclined to the downwind side in the same way as the canvas, so that the swing rod arranged in the automatic water distributor blocks the internal water channel of the downwind side and automatically opens the internal water channel of the upwind side, and the water passing through the internal water channel of the automatic water distributor is transmitted to the external pipe of the upwind side.

The tubes are arranged with the uppermost ends of the canvas in between and facing each other along the uppermost ends of the canvas to both ends of the canvas. The water passing through the external passage of the automatic water distributor is transmitted to the two ends of the uppermost end of the canvas through one of the two small pipes connected on the upwind side, and the water transmitted to the small pipe on the upwind side flows down to the upwind side of the canvas through a plurality of holes perforated obliquely downward from the pipe to the surface of the canvas, so that the upwind side surface of the canvas is wetted with the water all the time.

Since the canvas suspended on the balloon is swollen in the longitudinal and lateral directions in the same central portion as the canvas of the sailboat, the water receiving blocks should be provided at every appropriate height interval so as not to gather the water running down the upwind side surface of the canvas to the center, and the flow of the water can be dispersed more widely in the lateral direction.

Suitable places for hanging canvas on a balloon are the periphery of a factory where a large amount of pollutants are generated, rivers crossing the center of a city and the vicinity of rivers, the periphery of a large road where a large amount of soot is generated, and the periphery of an airport runway.

If the device is arranged around an airport runway frequently generating dense fog and smoke or yellow sand, the device can remove excessively increased moisture particles in the atmosphere at ordinary times, thereby preventing the fog and smoke from generating to a certain extent in advance, and not only the fog and the fog but also the yellow sand can be directly removed, so that the visibility can be actively improved, the flight delay can be reduced to the maximum extent, and the safe flight can be greatly improved.

Fog and smoke on the coast move in the direction of a tidal current that reverses direction four times a day. If a canvas hung on a balloon and constantly wetted with water is provided around an airstrip located on the coast, mist and smoke are prevented from moving by the canvas surface constantly wetted with water being adsorbed and removed while moisture particles contained in mist and smoke around the canvas are in contact with the canvas surface constantly wetted with water, and thus the mist and smoke gradually disappear. The fine dust contained in the smoke is automatically removed together with the moisture particles.

In the urgent situation where air pollution needs to be eliminated in a short time although the canvas is hung on a balloon in the air, although it is not beautiful, all methods should be tried as far as possible so long as the air pollution can be improved, and accordingly, if a landscape painting such as a landscape painting is printed on the surface of the canvas, the canvas can be used as a fine art and can be flexibly applied to commercial advertisements.

Since turbid water continues to fall under the canvas suspended on the balloon, people should not pass under the canvas, and the canvas is preferably installed in a limited place where contact with buildings and electric wires is completely impossible.

The water flowing down from the canvas is structurally difficult to recover, but contains a large amount of fine dust, which may be a source of other fine dust generation, and thus it is necessary to remove the fine dust as much as possible in order to maintain a clean environment around.

In a second embodiment, a dust removing apparatus for a method of directly removing floating dust by hanging canvas on a building, comprises: a water tank 2a for supplying water to canvas hung on a wall surface of a building; a pipe 2b for supplying water from a water tank 2a of a building to a surface of the canvas 2 f; a rope 2d connecting the wall surface 2g of the building and the upper end of the canvas 2 f; a tube 2e having a plurality of holes formed at a lower portion thereof for allowing water to flow from an uppermost end of the canvas 2f to a surface of the canvas 2 f; a canvas 2f for collecting floating fine dust by water flowing on the surface; the water supporting module 2h is arranged on the surface of the canvas, so that water flowing down from the canvas is not gathered to the center; and a rope 2i connecting the lower end of the canvas 2f with the ground surface.

The dust removing apparatus described above places the uppermost two ends of the canvas 2f at a high position on the wall of the building, respectively, and fixes the lowermost two ends of the canvas 2f to the ground surface at a predetermined distance from the building, whereby the side surfaces of the canvas 2f lean against the wall surface of the building.

The surface of the canvas 2f is constantly soaked with water flowing down along the surface of the canvas 2f inclined against the wall, and the dust floating and moving in the atmosphere is directly adsorbed and removed.

The water tank 2a is a water tank that supplies water to a pipe 2e provided in parallel at the uppermost end of the canvas 2f through a pipe 2b, or the water tank 2a is provided only in a case where a building water pipe cannot be used.

The rope 2d connects the wall surface and the uppermost end of the canvas 2f, and the rope 2i connects the lowermost end of the canvas 2f and the ground surface.

The tubes 2e are tubes through which water received by the other tubes 2b is transferred to the uppermost two ends of the canvas 2f, respectively, so that water injected through a plurality of holes perforated downward in the tubes 2e toward the canvas surface flows down along the surface on the canvas 2 f.

The canvas 2f is almost linearly fixed to the side surfaces of the canvas on the wall surface and the floor surface of the building, respectively, but when water continuously flows along the surface of the canvas 2f, the weight of the water is applied to the canvas 2f, and therefore the canvas 2f' is formed in a shape in which the canvas side surfaces sink downward.

Structurally, the water running down from the surface of the canvas 2f 'is gathered to the center, and therefore, in order to make the water running down from the surface on the canvas 2f' spread horizontally more widely, the water scooping module 2h is preferably provided.

As described above, incomplete combustion of many vehicles running at low speed in the center of the city causes a large amount of soot and fine dust to occur, and a large amount of fine dust also flows in from the outside.

However, since the dust particles are always in a high concentration due to the stagnation of the airflow in a high-rise building, it is very important to remove the dust particles in the centers of cities where many people live and pass for the health of people.

The canvas is hung on the wall at a high position, and the canvas is hung obliquely on the wall by fixing the canvas at its lower end to the ground surface at a certain distance from the building.

If water supplied to the uppermost end of the canvas flows down along the inclined surface of the canvas by being injected through the tubes connected to both ends along the uppermost end of the canvas and the plurality of holes perforated downward to the canvas at the lower ends of the tubes, the flowing water is used as an artificial catalyst to adsorb the fine dusts floating and moving around the canvas while contacting the fine dusts, and thus the fine dusts can be actively and directly removed.

In addition, the water flowing down along the upper surface of the canvas is contacted with excessive moisture particles in the atmosphere and simultaneously adsorbs the water separator, so that the condition that fog and smog are generated around the canvas is prevented to a certain extent in advance.

Therefore, if the minimum wind to move the fine dust is always soaked in the water flowing on the inclined canvas in each area with high fine dust concentration until the maximum wind, the fine dust floating in the atmosphere can be actively and directly removed.

However, before a strong wind of a predetermined or more is generated, the canvas should be collected and stored in a safe place.

The canvas can be used as a banner for commercial advertisement to be attached to a building in case of being reported in a city center while satisfying a predetermined condition.

However, the canvas is always dropped with turbid water, and therefore, the canvas should be installed in a place where no person passes or where safe passage is ensured.

The height from the ground, at which the fine dust directly affects the living environment of people, is about 10m, the fine dust gradually falls down in the wind, and the larger the area of the canvas wetted by water is, the more the canvas is inconvenient to carry, and the crisis coping ability is reduced, so that the possibility of safety accidents is increased, and the size of the canvas does not need to be enlarged.

In addition, in order to prevent water flowing down from the inclined surface of the canvas from being gathered to the center, it is preferable to provide the water scooping modules at appropriate height intervals.

The canvas is preferably installed in a place where people are as little as possible to pass through because turbid water continuously drops under the canvas hung on a building.

It is structurally difficult to recover the water falling under the canvas, but it contains a large amount of fine dust and thus is likely to be a source of generation of other fine dust, and therefore, for the purpose of cleaning the surrounding environment, it is preferable to remove the water falling under the canvas as much as possible,

in a third embodiment, a dust removing apparatus of a method for directly removing dust floating in the atmosphere by installing canvas or plastic plates on both sides of a wall or a fence, comprises: a canvas or plastic plate 3b covering the wall or iron fence; a pipe 3c for distributing water to the upper end of the canvas or plastic plate 3 b; a line 3d for supplying water from the pump to the line 3c for distributing water; a pump 3e for supplying water to the line 3 d; a water receiving frame 3f for collecting water flowing down from the canvas or the plastic plate 3 b; a water tank 3g for supplying water to the pump 3 e; a water tank 3h for recovering water flowing down from the water supporting frame 3f for purification; and a line 3i connected to a water tank 3g that supplies water subjected to a purification process in the recovery water tank 3h to the pump 3 e.

The dust removing apparatus described above removes floating dust directly by allowing the surface of the canvas or the plastic plate 3b to be wetted with water all the time by water continuously running down from the uppermost surface of the canvas or the plastic plate 3b, which completely covers the upper surface and both side surfaces of the wall or the fence 3 b.

When water pumped up from the underground water tank 3g by the pump 3e passes through the pipe 3d and the pipe 3c provided on the wall or the fence and continuously flows from the uppermost portion of the canvas or the plastic plate 3b covering the wall or the fence through a plurality of holes spaced at an appropriate distance below the pipe 3c, the surface of the canvas or the plastic plate 3b is always wetted with water, and therefore, fine dust floating in the atmosphere is removed by adsorbing the fine dust while contacting the surface of the canvas or the plastic plate 3 b.

The water flowing down from the surface of the canvas or plastic plate 3b is collected in the water receiving frame 3f and purified in the recovery tank 3h, and the purified water is moved to the water tank 3g through the pipe 3i and reused.

The less the wind, the more easily the fine dust floating and moving in the atmosphere is accumulated around the wall and the fence, and the fine dust re-accumulated on the ground surface after floating is repeatedly raised and lowered by the convection phenomenon of the air and is also accumulated on the ground surface again, so that the concentration of the fine dust around the wall and the fence where people live is always high, and therefore, the removal of the fine dust floating and moving around the wall and the fence is most important for the health of people.

If the two side faces of the wall and the fence with various heights for distinguishing the boundaries between lanes, lanes and sidewalks, lanes and buildings and between buildings in a city are in a dry state, even if the wind blows the tiny dust in the air, the tiny dust only passes through the fence directly.

However, if the surfaces of the canvas or plastic panels provided on both sides of the wall and the fence are always in a state of being wetted with water, the water flowing down as if the fish school is trapped in the water in the stationary net comes into contact with the fine dust floating on the ground surface as an artificial catalyst and adsorbs the fine dust, so that the fine dust and soot can be directly removed.

In addition, since the adsorption and removal can be performed from the initial stage of the diffusion of the excessively increased moisture particles, the generation cause of mist and smoke can be isolated to some extent in advance in the vicinity.

Therefore, if the surfaces of the canvas or the plastic sheet on both side surfaces of the wall or the fence in each area where the fine dust and the soot are generated are always wetted with water, the fine dust and the soot can be actively and directly removed from the initial stage of the diffusion of the fine dust and the soot in each area, and thus the atmospheric environment can be effectively improved.

In order to prevent the water flowing from the surface of the canvas or the plastic plate attached to both side surfaces of the wall or the fence from being collected in one direction, it is preferable to provide water receiving frames for horizontally dispersing the flow of the water at every appropriate interval height of the canvas or the plastic plate.

In addition, the canvas and the plastic plate are preferably firmly provided so that they can withstand strong wind.

If a central isolation zone of a road on which vehicles often run is installed in a place where a large amount of pollutants are generated, particularly, a boundary line between a city center road and a sidewalk where automobiles and human beings frequently pass, a large amount of fine dust and soot cannot be adsorbed through a boundary line between canvas and a plastic plate which are wetted with water all the time just as if fish flocks are trapped in a fixed net in water, so that a large amount of fine dust and soot can be directly removed at the initial stage of diffusion, and a good effect of removing the fine dust and soot can be obtained.

The turbid water collected by flowing down from the lower side of canvas or plastic arranged on the wall and the fence contains a large amount of micro dust, and the water can also be a source for generating other micro dust, so that a drainage channel is arranged as far as possible to remove the turbid water, and the turbid water is preferably purified and reused in an economical direction.

A fourth embodiment is a fine dust removing apparatus of a method for directly removing fine dust floating in the atmosphere by installing a water receiving rack on a wall surface of a building, including: a water tank 4b for supplying water to a wall surface of a building; a water receiving shelf 4c for allowing water flowing down from the water receiving shelf 4k to directly flow down before being scattered and splashed to the outside; a water holding rack 4d which is positioned at the lower part of the water holding rack 4c and collects the flowing water and conveys the water to a water tank 4 e; a water tank 4e which is located at a lower portion of the water receiving shelf 4d and collects water flowing down; a structure 4g for fixing the water supporting frame 4c to a building wall; a water passage 4h for allowing water collected in the water receiving shelf 4c to directly flow downward; a pipeline 4i for conveying water from the water tank 4b to the water rack 4k at the uppermost end of the building; a pipe 4j provided transversely to both ends inside the water receiving frame 4k at the uppermost part of the building and having a plurality of holes perforated with appropriate intervals; and a water holding frame 4k having the same structure as the water holding frame 4c provided at the lower part of the pipe 4j, and having the pipe 4j provided horizontally inside.

The micro dust removing device can adsorb micro dust floating and moving in the atmosphere, so that the wall surface of a building is always wetted by water, and the micro dust is directly removed.

A water tank 4b is provided to supply water from the uppermost part of a building to a wall surface, a water receiving shelf 4k is provided to form a water film of uniform thickness from the uppermost part of the building, and if water is to be drained, a water receiving shelf 4c is provided to allow water flowing down along the wall surface of the building to flow down directly while being gathered to the wall surface before the water film is scattered at a predetermined height.

Then, a water receiving rack 4d for collecting water flowing down along the wall surface of the building is provided below the building, and the water collected by the water receiving rack 4d is stored in a water tank 4e, and the collected water is reused if necessary.

The areas of most buildings are places where dust removal is prioritized, and the air flow of high-rise buildings is somewhat stagnant, so the dust concentration is relatively higher than that of areas without high-rise buildings, and most people live together, so dust removal in the air is prioritized for people's health.

The fine dust floating and moving around the building directly passes through the dry wall surface, and conversely, if the building wall is always wetted by flowing water, the flowing water is used as an artificial catalyst to promote the fine dust floating and moving in the atmosphere to be contacted and adsorbed, and further, the fine dust can be directly removed.

Therefore, when the wall surface of the building is constantly wetted with flowing water in each area having a high concentration of fine dust, the fine dust floating around the building is adsorbed while contacting the flowing water, and the fine dust can be directly removed.

Further, the air flow is stopped to form mist and smoke, but the mist and smoke move in the end, so that moisture particles contained in the mist and smoke are adsorbed by water flowing down from the wall surface and removed, the mist and smoke disappear, and fine dust contained in the smoke is automatically removed together with the moisture particles.

In addition, moisture particles are removed whenever the moisture concentration in the atmosphere exceeds a predetermined reference, thereby preventing generation of a cause of fog and smoke to some extent.

However, when water continuously flows out from the uppermost end of the building by forming a water film of uniform thickness, the water flowing down comes into contact with the wall surface due to the difference in the thickness of the water and flows down, and further, because of the difference in the falling speed between the water subjected to relatively high friction and the water slightly separated from the wall surface and subjected to relatively small friction, the water film of uniform thickness starts to diverge when the water flows to a predetermined height or less, and the longer the falling distance is, the water gradually splashes to the outside while being concentrated in various directions, thereby affecting the periphery of the building.

Even in this case, if the water supply amount is increased, the area to be wetted with water is not increased, but the amount of water splashed to the outside is increased, which affects the periphery and greatly increases the water consumption.

Therefore, if the water receiving frame is provided and the water flows directly downward while being collected at intervals of an appropriate height along the water film flowing down the wall surface before being diverged, the water flowing down the wall surface having a height of several tens of meters is not splashed to the outside at all, and the water film having the initial thickness is theoretically maintained uniformly, so that the fine dust floating in the air can be directly and effectively removed, and the water consumption can be reduced to the maximum extent.

Although facilities that do not splash water running down a wall surface having a height of about 7m to the outside are seen in a room without the influence of wind, it is preferable to adjust the interval and the operation time of the height of the water racks in consideration of the intensity of wind because the outer wall of the building is always influenced by wind.

Since the wall surface of the windowed apartment house is excessively protruded to cause water to be splashed to the outside, it is preferable to provide the wall surface without a window. Recently constructed glass wall buildings have windows, but there is no protruding structure, and the outer wall is vertical, so that a water supporting frame which does not damage the appearance of the wall surface can be installed, but it is inevitable that the water supporting frame is damaged in the process of cleaning the glass wall, and the height at which fine dust directly affects people's life is about 10m or less from the ground, so that the glass wall building can be effectively operated by installing the glass wall building at a height which can be cleaned by an overhead ladder.

When the dust collecting device is installed on the wall surfaces of apartment communities where dust has to be stopped by high-rise buildings and high-rise buildings in the city center, dust floating around the periphery can be directly and effectively removed. If water flows continuously on the walls of apartments and buildings, the air environment is improved as if there is a small forest around the periphery, and the flowing water produces anions, which is beneficial to health.

The turbid water flowing down and collected under the building can be reused in an economic aspect, a drainage channel needs to be arranged for cleaning the surrounding environment, and the turbid water collected under the wall surface of the building contains a large amount of fine dust, so the turbid water also becomes a source for generating other fine dust, and the turbid water is preferably removed as far as possible.

It is apparent to those skilled in the art that the present invention described above is not limited by the above-described embodiments and drawings, but various substitutions, modifications and changes may be made without departing from the technical spirit of the present invention.
