Reference numeral 1 denotes a display tower with an air purification device, and the display tower 1 with an air purification device is one in which an air purification device 5 is incorporated in a rectangular column-shaped display tower 3 that stands on a sidewalk and indicates a bus stop. . The air purification device 5 has an opening 7 formed in the side surface 301 of the display tower 3, a soil storage part 9 provided at the upper part of the display tower 3, and a plant 11 planted in the soil storage part 9. Soil 13
Air flow means 15 for passing the contaminated air from the surface of the soil 13 toward the bottom of the soil 13 and blowing the air out of the display tower 3 from the opening 7.
Are formed in two vertically adjacent slits on two adjacent side surfaces 301 of the display tower 3.

[0006] The soil container 9 is provided with a side surface 30 of the display tower 3.
The upper part is formed in an open shape by four side plates 17 forming one and a bottom plate 19 provided at a position near the upper part inside the display tower 3. The soil 13 is a soil in which microorganisms can propagate, for example, black soil. The soil 13 is formed by mixing pearlite or the like based on the above-mentioned black soil or the like to increase the porosity. Further, in this embodiment, a crushed stone layer 21 made of crushed stone is formed at the bottom of the soil 13, and a perforated pipe 23 is buried in the crushed stone layer 21, and the perforated pipe 23 and the crushed stone layer 21 uniformly spread from the bottom of the soil 13. It is configured so that air can be sucked in.

The air flow means 15 is a pump (or blower) 3 disposed below the bottom plate 19 inside the display tower 3.
1, an intake pipe 33 connected to the pump 31 and hermetically penetrating the bottom plate 19 and connected to the perforated pipe 23; an exhaust pipe 35 connected to the pump 31; and an open pipe connected to the exhaust pipe 35. The exhaust pipe 35 has a vertically elongated outlet pipe 37 attached to the exhaust pipe 35. The downstream portion of the exhaust pipe 35 is branched into two branches, and the outlet pipe 37 is connected to each end.

Further, in this embodiment, a water supply device 41 for supplying water to the plant 11 is attached to the display tower 3. The water supply device 41 includes a water tank 43 disposed on a sidewalk inside the display tower 3, and a water tank 43, which is erected upward from inside the water tank 43 and is provided with a bottom plate 1.
9 comprises a water supply pipe 45 which penetrates airtightly and projects above the soil 13, and a pump 47 interposed in the water supply pipe 45. Water supply to the plant 11 by the water supply device 41 may be performed by operating a switch of the pump 47 when an operator patrols, or a humidity sensor may be provided in the soil 13 and the humidity sensor may be used. It may be performed automatically, for example, by operating the pump 47 for a certain time when the detected humidity value falls below a predetermined value.

In the drawing, reference numeral 51 denotes a drainage pipe, which prevents rainwater from staying in the soil storage portion 9. Water discharged from the drainage pipe 51 is the same as the drainage pipe. When the water flows into the tank 43 and overflows from the water tank 43, the water is discharged from the lower end of the display tower 3 toward the roadway. Furthermore,
Although not shown, a check port that can be opened and closed is provided on the side surface of the display tower 3 so that maintenance inside the display tower 3 and water supply to the water tank 43 can be performed.

Next, the operation will be described. The power supply is connected and the pump 31 is rotated. By the rotation of the pump 31, the air in the rock layer 21 is sucked from the perforated pipe 23, and is blown out from the opening 7 through the suction pipe 33, the exhaust pipe 35, and the blowing pipe 37. Due to the suction of the air in the rock layer 21, the contaminated air is sucked from the surface of the soil 13 and flows toward the rock layer 21.

[0011] When the contaminated air passes through the soil 13, dust is trapped and impurities such as hydrocarbon gas such as methane are adsorbed by the physical action of the soil 13 as a filter. In addition, microorganisms decompose pollutants such as impurity components. Aerobic microorganisms proliferate on the surface of the soil 13 or on the portion where the air flows inside the soil 13, and anaerobic microorganisms proliferate on the portion where the air does not flow inside the soil 13, and these microorganisms grow. For example, carbon monoxide is mainly converted into carbon dioxide, nitric oxide is mainly converted into nitrate ions, and methane gas is mainly converted into carbon dioxide by being consumed in the cells of the bacteria and used for respiration. Decomposes into water and thus removes contaminants. That is, clean air from which contaminants have been removed is blown out from the opening 7 on the side surface 301 of the display tower 3.

As described above, according to the present embodiment, the air purification device 5 is incorporated in the display tower 3 installed at the bus stop so that clean air is blown from the display tower 3.
People waiting for buses under heavy traffic and polluted air can inhale clean air. That is, clean air drifts in the vicinity of the display tower 3, and the plant 1
Since 1 is planted, it is possible to use a bus stop that gives a sense of comfort to the surroundings, instead of a bus stop that was cut down as in the past.

In the embodiment, the case where the air purification device 5 is assembled to the display tower 3 installed at the bus stop has been described. However, the display tower 3 to which the air purification device 5 is assembled is optional. The present invention can be applied to various display towers 3 installed in a venue, a park, a roof of a department store, or the like.

Further, in the embodiment, the contaminated air is sucked in from the upper part of the display tower 3 and the clean air is blown out from the side face 301 of the display tower 3. 13 may be allowed to pass upward from the bottom, and clean air may be blown out from the upper part of the display tower 3.

[0015]

As is apparent from the above description, according to the present invention, various display towers such as those installed at bus stops are used to purify the air in the soil where plants are planted. So let the clean air drift near these display towers,
It is possible to give a sense of comfort near the display tower.
