In addition, the body part 3 is equipped with a pollution level meter (not shown) on one side of the inner surface or the outer surface of the outer body 11, and measures the concentration of foreign substances in the receiving space 17 to visually or audibly By displaying the concentration, both the user inside the receiving space 17 or a non-user outside the receiving space 17 can easily check the degree of contamination of the receiving space 17.

The intake part 5 is an air supply means for inhaling outside air into the receiving space 17 of the trunk part 3, and as shown in FIG. 2, one or more of them penetrate the body part 11 of the body 3 It is installed in such a way that clean outside air can be supplied to the receiving space 17 by filtering foreign substances in the outside air at the same time as suction.

To this end, the intake part 5 is preferably composed of an assembly of a fan 21 and a filter 23 known as a fan filter unit (FFU), as shown in FIG. 4, but a separate fan 21 and The filter 23 can also be assembled and configured. At this time, various types of fans such as a centrifugal fan or an axial fan may be employed as the fan 21, and a HEPA or ULPA filter may be employed as the filter 23. However, in the fan filter unit used as the intake part 5, the axial fan 21 and the filter 23 are sequentially installed in the case 25 along the airflow, and the intake hole 27 is located in the center of the upper surface of the case 25. Formed, and the base is wide open. In addition, in this embodiment, as shown in FIG. 2, the intake part 5 is installed on the upper surface of the body part 3, and when the system 1 is installed outdoors, the air intake hole 27 As shown in FIG. 4, it is preferable to mount a protective cover 29 over the intake hole 27 to prevent snow from entering and allow the flow of outside air.

In addition, the intake part 5 may be provided with a warning device such as an alarm so that the administrator can easily identify the replacement timing of the filter 23.

The exhaust part 7 is an exhaust means for discharging the inner air of the receiving space 17 of the body part 3 to the outside, and as shown in FIG. 2, as shown in FIG. 3) As a bar installed through the outer body 11, the inside air is discharged to the outside and at the same time, foreign substances in the inside air are filtered so that the inside air in a clean state is discharged to the outside.

To this end, it is preferable to employ a fan filter unit as shown in FIG. 4 as for the exhaust part 7 as well as the intake part 5, but it may be configured by assembling a separate fan 21 and a filter 23. have. However, the exhaust part 7 is arranged such that the fan 21 is located inside and the filter 23 is located outside along the airflow of the exhaust, and is installed on the outer body 11 located on the side in consideration of the flow of the inside air. . In this way, the exhaust part 7 is installed on the outer body 11 on the side, and further discharges the inner air to the outside, so the protective cover 29 can be omitted, but the filter 23 is outside the body part 3 It is desirable to install a protective cover or cover on the exit side to reduce or eliminate the influence of rain, snow or wind.

In this way, the intake part 5 and the exhaust part 7 can be installed at any position of the outer body 11 as long as it is possible to inhale outside air into the accommodation space 17 or discharge the inner air of the accommodation space 17 to the outside. Do. However, as mentioned above, as shown in FIG. 2, the intake part 5 is installed on the upper outer body 11 so that the freshly introduced clean intake air first directs toward the user's head, and conversely, separated from the user. The exhaust part 7 is preferably installed under the side outer body 11 so that the bet containing foreign matter can be discharged downward. In addition, as shown in Fig. 2, the intake part 5 and the exhaust part 7 are provided in more than one bar, and in general, both of them perform the intake and exhaust operation continuously for 24 hours, but some of them correspond to each other. You can also work in pairs. At this time, it is preferable that the intake part 5 and the exhaust part 7 forming the same pair are located at opposite points so that the bet can convectively convectively the entire receiving space 17. That is, for example, as shown in FIG. 3, the intake part 5-1 disposed in the rear left corner of the upper surface of the outer body 11 is paired with the exhaust part 7-1 disposed in the front right corner. When built, only the intake part 5-1 and the exhaust part 7-1 are movable, thereby making it possible to create an airflow that largely flows in the diagonal direction in the accommodation space 17.

Furthermore, the intake part 5 and the exhaust part 7 are made into a group as described above, and the group is sequentially operated, thereby continuously generating an airflow in the same direction in the receiving space 17 to amplify the flow of bet. have. That is, for example, 1 set of the intake part 5-1 and the exhaust part 7-1 of FIG. 3, 2 sets of the intake part 5-2 and the exhaust part 7-2, and the intake part 5- If 3) and the exhaust part (7-3) are paired into 3 pairs, then the 1, 2, 3 groups are sequentially turned on and off, and the flow of the bet continues in one direction in the counterclockwise direction on the drawing, accelerating and amplifying. As a result, internal cleaning efficiency is increased.

In addition, the intake part 5 and the exhaust part 7 recognize the user's position by a separate user sensor (not shown) and operate only a pair that forms airflow to the corresponding position or operate first, that is, the user is detected. By forming an airflow only in a specific area within the receiving space 17, it is possible to increase the efficiency of consumption of energy required for operation.

On the other hand, as another embodiment of the present invention, the fine dust evacuation and reduction system 1 may further include an air shower room 31 installed at one side of the entrance 13, as shown in FIG. 5.

The air shower room 31 forms an independently sealed air shower space 30 between the outside and the accommodation space 17 as well as the outside so as to be blocked from the accommodation space 17, the entrance 13 When the door (15) is opened, outside air is not easily introduced into the accommodation space (17). In addition, the air shower room 31 is a strong shower air intensively to the user before the user entering the narrow space called the air shower space 30 enters the accommodation space 17 immediately after or immediately before passing through the entrance 13 By spraying, foreign matters on the user are effectively separated within a short time. As a result, the amount of foreign matter flowing into the receiving space 17 is reduced, making the bet more comfortable. However, the air shower room 31 has a shield 33 surrounding the air shower space 30, like the body 3, so as to remove foreign matters separated from the air showered user or introduced from the outside through the entrance 13 ) Or an air shower exhaust unit 39 similar to the exhaust unit 7 on one side of the outer body 11 may be penetrated and installed as shown in FIG. 5. At this time, the air shower exhaust unit 39 is also composed of a fan filter unit like the exhaust unit 7, and thus, the inside of the air shower space 30 is discharged to the outside or to the receiving space 17 while simultaneously betting. By filtering foreign substances in, clean air is discharged to the outside or to the receiving space 17.

As such, the air shower room 31 includes a plurality of shields 33 and an air shower injection port 37 as shown in FIG. 5.

Here, the shielding body 33 is coupled to the outer body 11 of the adjacent body 3 so as to communicate with the entrance 13 in the form of a booth to form a sour space 30, which is made of the same material as the outer body 11 It is okay to be. In addition, the shielding body 33 is integrally installed in the interior adjacent to the entrance 13 of the accommodation space 17 surrounded by the outer body 11, or adjacent to the entrance 13, as shown in FIG. It may be installed integrally at a location outside the outer body 11. In addition, an air shower door 35 connected to the entrance 13 is installed on one side of the shield 33, and the user moves from the air shower space 30 to the accommodation space 17 through the air shower door 35 You will be able to.

In addition, the air shower injection port 37 is a device that injects high-pressure shower air into the air shower space 30, and is mounted on one side of the air shower space 30 such as the ceiling of the air shower room 31. A strong shower air is injected to the user waiting in the space 30 to separate various foreign substances from the user. To this end, the air shower injection port 37 may provide a high-pressure shower air to the air shower injection port 37 by installing a separate high-pressure gas cylinder, but the passage is connected to one side of the outlet of the exhaust part 7 on one side. Filtered air discharged from the exhaust part 7 may be recycled as shower air. At this time, if necessary, a compression device may be placed on the passage to compress and use the exhaust air of the exhaust unit 7.

In addition, as another embodiment of the present invention, as shown in FIG. 6, an air curtain 41 may be installed around the entrance 13.

The air curtain 41 is a device for preventing the outside air from flowing into the receiving space 17 through the door 13 when the door 15 of the door 13 is opened, and is provided on one side of the receiving space 17, for example. , As shown in FIG. 6, it is composed of a curtain ejection opening 43 in the form of a duct mounted along the edge of the entrance (13). Therefore, the curtain injection port 43 forms a single conduit connected in a rectangular shape, and a high-pressure blocking air is injected from a plurality of injection ports arranged toward the center of the door 13 toward the center of the door 13. Accordingly, the air curtain 41 blocks the entrance 13 by the high-pressure blocking air when the entrance 13 and the door 15 is opened, so that outside air is easily transferred to the accommodation space 17 through the entrance 13. Prevent entry.

At this time, the air curtain 41 can receive high-pressure cut-off air by installing a separate high-pressure gas cylinder, like the air shower room 31, but by connecting a passage to one of the outlets of one exhaust part 7 Filtered air discharged from the exhaust part 7 can be recycled as cut-off air. Even at this time, a compression device may be placed on the passage to compress the air discharged from the exhaust part 7 and use it as blocking air.

Now, the operation of the fine dust evacuation/reduction system 1 of the present invention according to a preferred embodiment of the present invention will be described as follows.

The system (1) of the present invention may be used indoors in the form of a clean room, or may be used outdoors as a shelter for pollutants in the air. In either case, the body ( 3) When the outside air is introduced into the interior, all foreign substances in the outside air are removed by the intake part 5 and the filter 23, so that the user who enters the space inside the body part 3, that is, the receiving space 17, is contaminated. It is protected by being blocked from outside air, and it is possible to breathe the air in the receiving space 17, that is, clean air in the inside air.

In addition, as the user's access is accumulated, various types of foreign matters originated from the user increase during the bet in the accommodation space 17, but since the bet containing foreign matters is discharged to the outside by the exhaust part 7, the accommodation space (17) can be kept in a clean state.

Moreover, since foreign matter in the internal air discharged to the outside through the exhaust part 7 is removed by the filter 23 of the exhaust part 7 in the process of being discharged, the exhaust part 7 furthermore, a fine dust evacuation and reduction system Around (1), the degree of cleanliness is increased by the clean air discharged from the exhaust part 7. That is, the degree of contamination is reduced. Therefore, the system 1 also serves to reduce the concentration of contaminants such as fine dust around. In addition, when the number of systems (1) installed for shelters at roadside bus stations in urban areas with high pollution levels due to smoke or fine dust increases and becomes larger, the system 1 basically inhales the polluted air around it, Since the internal air from which pollutants have been removed is discharged to the outside, an additional effect of improving the air cleanliness around the installation location can be expected.

In addition, the system 1 can operate or stop the entire intake part 5 and the exhaust part 7 at the same time, but it is possible to increase energy efficiency by partially squeezing a tank and operating each group. At this time, if the intake part 5 and the exhaust part 7 of the same group are set as far apart as possible, the flow of air in the accommodation space 17 increases, thereby reducing the cleaning time of the accommodation space 17 and improving the cleaning efficiency. You can increase it. In addition, if the intake part 5 and the exhaust part 7 are controlled to be sequentially operated and stopped for each group, the airflow in the same direction is continuously generated in the accommodation space 17, so that the air flow inside the accommodation space 17 is controlled. It can be amplified, and thus internal cleaning efficiency can be increased.

In addition, the user can use the system 1 safely, comfortably, and conveniently as mentioned above by various additional devices or facilities installed on the body part 3, as shown in FIG. 3 when used as a shelter. As it has been, it is possible to achieve excellent outdoor advertising effects through advertisement means 19 such as advertisement boards installed inside and outside the body 3.

In addition, in the case of the system 1 shown in FIG. 5, the user once enters the air shower room 31, closes the door 15, and removes foreign substances from the body with the shower air sprayed from the air shower injection port 37. After removing the first, since the air shower door 35 is opened to enter the receiving space 17, external air can be prevented from entering the receiving space 17 directly through the entrance 13. In addition, since foreign matter is firstly removed from the user before entering the accommodation space 17, it is possible to suppress an increase in the degree of contamination of the accommodation space 17.

In addition, in the case of the system 1 shown in FIG. 6, as in the embodiment of FIG. 5, when the user opens the door 15, the air curtain 41 operates and the blocking air is injected from the curtain injection port 43. As a result, since the entrance 13 is blocked from the outside, it is possible to prevent the outside air from easily flowing into the accommodation space 17 through the entrance 13. In addition, it is possible to expect an effect of removing some foreign substances from the user passing through the blocking air. This is the same when the user opens the door 15 in the accommodation space 17 and comes out.
