The present invention relates to a mobile air purifier for underground living spaces capable of efficiently removing dust and contaminants to provide clean air as well as cleaning floors.

       Full-scale development and use of underground spaces began to develop as the economy developed after the 1970s, and the economic and environmental necessity of cities and their availability as industrial facilities.

       In the 1970s, underground development was expanded to expand urban transportation facilities such as subway line 1 and Namsan 1, 2, and 3 tunnels, and underground streets and underpasses in subway stations were actively developed. In the 1980s, the development of subway lines 2, 3 and 4, the underground linkage project between the historic connecting sections of subway lines 2 and 3, and the systemization of joint districts following the development of new cities were carried out. Since the 1990s, underground transit stations and underground shopping centers have been established and operated by the construction of subway lines 5, 6, 7, 8, and 9 and the construction of urban subways.

       In recent years, ground development has been developed and operated more concretely and extensively to use underground space as an alternative to saturation and urban traffic problems.

        The use of these underground living spaces has the advantage of solving urban problems due to its excellent accessibility such as diversification of urban structure and transportation when making underground facilities with buildings on the ground in urban areas with high population density and high land prices. In order to utilize the space, there are not many tasks to solve, but one of the biggest problems is air. In general, when the space is below 3 stories, the outside air is purely attracted by the air pressure. It was difficult to reach the space.

Therefore, in the case of underground shopping malls and subways that are constructed and operated in the depth of the underground, workers and users may be uncomfortable as well as long-term if they are not well ventilated due to fine dust, carbon dioxide, formaldehyde, radon and harmful substances. Exposure to the environment can adversely affect health.

Accordingly, in order to improve the indoor air quality of the underground space by introducing fresh air into the closed underground space, most of the underground facilities in the underground living space are provided with external air inlets. It shows the adverse effect that the compressed air acts as a contaminant passage into the underground space.

       In particular, in the case of subway history, an air circulation system is introduced to forcibly introduce and ventilate the outside air into the basement, but in this case, installation, operation, and exchange in all sections takes enormous costs, and thus not only the operator, but also the user, It is placing a heavy burden on consumers, and furthermore, in order to save energy by increasing oil prices, air pollution is serious in underground living spaces due to reducing the operating time and frequency of the ventilation system.

1 and 2, the mobile air purifier for underground living spaces of the present invention has wheels 11 formed to freely move passageways and platforms of subway stations where people concentrate, and thus, power from the battery 12. The electric vehicle 10 is supplied with the brush, the brush 50 provided in the electric vehicle 10 for cleaning the floor, and is mounted on the electric vehicle 10 to remove fine dust and contaminants contained in the air It consists of a dust collector 20 for supplying clean air.

Since the electric vehicle 10 needs to move freely through the passages, platforms and underground shopping centers of subway stations, it is preferable that the electric vehicle 10 uses electric energy, which is clean fuel, as a power source, rather than fossil fuel emitting exhaust gas.

The electric vehicle 10 is provided with a battery 12 is charged with electrical energy, it is moved by the electrical energy supplied from the battery 12, it is limited to a certain speed for safety when driving and is free to move The urethane wheel 11 is formed so that a noise may fall.

The electric vehicle 10 is equipped with a compressed air supply device 40 for supplying compressed air into the dust collector 20 and the filter 27 provided in the dust collector 20.

3 and 4 is a view showing a dust collector, as shown in the dust collector 20 is a suction of the outside air containing a large amount of fine dust and pollutants to remove the fine dust and contaminants from the air clean air As it is discharged to the outside, the air inlet 21 is formed to have a predetermined space therein to suck air from the outside, and fine dust and pollutants from the air introduced from the air inlet 21 therein. A plurality of cylindrical filters 27 are separated and stacked, and an air outlet 23 through which the clean air from which fine dust and contaminants have been removed by the filter 27 is formed on a rear surface or a side surface or an upper surface thereof. The lower part is formed with a pollutant outlet 25 through which the fine dust separated from the air by the filter 27 and the pollutant is discharged, and the air outlet 23 is provided with air blowing. A turbine fan 24 is formed.

The dust collector 20 formed as described above generates a negative pressure inside the dust collector 20 by the operation of the turbo fan 24, and thus air such as a passage in a subway station, a platform, and an underground mall is the air suction port ( 21 is naturally introduced into the dust collector 20, and the air introduced into the dust collector 20 is filtered from the outside of the filter 27, as shown by the arrow shown in a large solid line in FIG. 27, that is, through the filter 27 and is discharged through the air outlet 23 communicating with the internal space of the filter 27.

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

The filter 27 is made of a synthetic resin material having pores of 0.2 μm to 2 μm, and as shown in FIG. 5, the filter 27 has a cylindrical shape having wrinkles formed on an outer surface thereof.

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

The filter 27 is any one of polyethylene (PE, Polyethylene), polypropylene (PP Polypropylene), glass fiber (Glass Piber), Nomax (Nomex), acrylic (Tcrylon), Teflon (Ryton) It is made of one or a mixture of them, as shown in Figure 5, the outer surface of the filter 27, the filter 27 in the process of moving the filter 27 and insertion and withdrawal of the filter 27 ), And the metal mesh 27a may be formed to maintain the external shape of the filter 27.

The dust collector 20 is to purify the air by removing the fine dust and contaminants from the air containing a large amount of fine dust and contaminants as described above, at least one or more air purification filters 27 therein It is preferable that the filter 27 is stacked in view of the filtration and replacement and management of dust falling freely by the flow of air without vortex phenomena and re-scattering in the dust collector 20. Preferably, the dust collector 20 is provided in the horizontal direction so as to be inserted and withdrawn in the horizontal direction.

An air inlet 21 through which air from the upper atmosphere is introduced into the dust collector 20 is formed on the dust collector 20, and the air outlet 23 and the fine dust and the air are discharged from the dust collector 20. As the pollutant outlet 25 through which the material is discharged is formed at the side and the bottom of the dust collector 20, the upper polluted air sucked by the air suction port 21 flows down inside the dust collector 20. (down-flow) In other words, as air flows from the top to the bottom, fine dust and contaminants contained in the air freely fall in this process to naturally separate from the air, and vortex is generated inside the dust collector 20. In other words, the fine dust and contaminants separated from the air are scattered again, which does not deteriorate the performance of the filter 27.

In addition, the air inlet 21 of the dust collector 20 is formed to extend to the lower side of the electric vehicle 10 through the air suction pipe 55, the air in the lower air flows into the dust collector 20.

Thus, as a lot of crowds or equipment moves, dust scattered from the floor is sucked through the air inlet 21 through the air inlet pipe 55, and the fine dust and contaminants thus sucked are up-flowed. After being moved from the bottom to the top in a manner, the dust collector 20 is introduced into the dust collector 20 and is processed in a downflow manner, thereby providing more efficient purification.

At this time, the air inlet 21 is formed with a hood 22 to limit the intake of foreign matter large particles.

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

As air purification progresses through the dust collector 20, fine dust and contaminants adhere to the outside of the air purification filter 27 provided in the dust collector 20, thereby degrading the performance of the filter.

In order to prevent this, high-pressure air is supplied into the filter 27 from the compressed air supply device 40 mounted to the electric vehicle 10 together with the dust collector 20.

The compressed air supplied from the compressed air supply device 40 is discharged into the internal space of the filter 27 through the compressed air injection nozzle 30 provided at one side of the internal space of the filter 27. Positive pressure is instantaneously generated in the internal space of the 27, so that the compressed air inside the filter 27 is discharged from the inside of the filter 27 as shown by the arrow shown by a small dotted line in FIG. 4. Is discharged to the outside.

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

The fine dust and pollutants that are separated from the filter 27 by the high pressure compressed air injected by the compressed air supply device 40 are pollutant outlets formed in the lower part of the dust collector 20 due to the action of gravity. Stacked on 25) side, it is discharged to the outside.

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

The dust collector 20 is preferably formed with a guide rail 28 for guiding the insertion and discharge of the filter 27, the inner side and the outer side of the dust collector 20 in the side in which the filter 27 is inserted and discharged Preferably, the door 29 for opening is provided.

On the other hand, the electric vehicle 10 is provided with a brush 50 that rotates in contact with the bottom surface for cleaning the floor as well as the air purification function, the washing water injection device 60 for spraying the washing water on the bottom surface. .

Due to the rotation of the washing water and the brush 50 sprayed from the washing water spraying device 60, various contaminants stuck to the bottom surface are removed to keep the floor clean.

At this time, the washing water spraying device 60 is preferably further provided with a waste water recovery means 65 which is sprayed to the floor through the washing water spraying device 60 to recover the waste water mixed with contaminants, the washing water spraying device ( A washing water storage tank 61 for supplying the washing water to 60 and a wastewater storage tank 66 for temporarily storing the wastewater recovered by the wastewater recovery means 65 are formed.

In addition, the air inlet 21 of the dust collector 20 has an air suction pipe 55 is formed to extend directly to suck the contaminants separated from the floor by the brush 50 into the dust collector 20, the air suction pipe 55 is further provided with a hood 22 for filtering large contaminants.

As the air suction pipe 55 extends from the air suction port 21 through which air is sucked into the dust collector 20 toward the brush 50, contaminants and scattered from the bottom surface due to the brush 50 are scattered. As the fine dust is directly sucked into the dust collector 20 through the air suction pipe 55, secondary pollution is prevented from occurring due to the operation of the brush 50.

As described above, the air suction port 21 may be formed to communicate with the brush 50 through the air suction pipe 55 having the hood 22 formed at one end thereof, and the hood formed on the dust collector of the present invention. It may be formed to be in direct communication with the outside through 22).
