Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an air purification facility and a purified air supply system using an air purification action of a plant or soil.
[0002]
[Prior art]
Conventionally, it is known that bacteria in plants and soil have a function of purifying air by their carbon dioxide assimilation effect and organic substance decomposition effect. There is an example of using in a sealed narrow space like.
[0003]
That is, as shown in FIG. 6, a water reservoir 53 for storing excess water is provided inside a cylindrical container 52 that is open at the top and has a large number of through holes 51 in the side wall. A mortar-shaped storage device 54 is placed on the part, a small suction fan 55 is disposed on the lower outside of the bottom of the storage device 54, and a suction pipe 56 connected to the fan 55 is disposed upward from the center of the bottom of the storage device 54. The activated carbon and the soil (hereinafter simply referred to as soil etc. 57) are put into the container so as to cover the suction pipe 56, and a plant 58 is planted in the soil etc. 57. .
[0004]
Then, by driving the suction fan 55 of this apparatus, air outside the system is sucked into the suction pipe 56 via the plant 58, soil, etc. 57, and the purified air is discharged from the through hole 51 of the container 52. It is what is done.
[0005]
In this case, when the air outside the system passes through the soil etc. 57, the water in the soil etc. 57 is evaporated. Therefore, it is necessary to water the plant frequently so that the roots of the plant are not dried.
These soils 57 are required to allow air to pass through easily (excellent air permeability).
[0006]
[Problems to be solved by the invention]
However, when water is supplied to the soil or the like, fine particles having a particle size such as soil flow into the gaps having a coarse particle size together with the water, and the gaps are gradually filled to deteriorate air permeability.
[0007]
In addition, if the frequency of watering is too high, nutrients and bacteria in the soil, together with excess water, fall from the container 54 and flow out to the water reservoir 53 built in the container 52, so fertilizer is supplied frequently. It had to be troublesome.
[0008]
Activated carbon, on the other hand, has a high adsorptive power at the beginning of use, but the adsorptive power tends to decrease due to frequent supply of water and fertilizer, and its purification action continues only for a short period of time. Compared to expensive.
[0009]
As described above, the soil or the like has to be replaced in a short period of time, and this replacement operation often damages the roots of the plants and causes the plants to wither.
Furthermore, since it is necessary to exchange soil, it is difficult to use a very large plant, it is difficult to secure a large amount of air purification capability, and it is unsuitable for a wide open space.
[0010]
Therefore, in view of the above prior art, the air purification equipment and the purified air supply system of the present invention do not require the labor of water supply and drainage, can be used for a long time without exchanging the soil, and can be used in large spaces at a low price. The purpose is to supply purified air.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of an air purification facility and a purified air supply system according to the present invention will be described with reference to the drawings.
[0023]
As shown in FIG. 1, the air purification equipment A according to the present invention is configured such that the first layer 1 is coarse, the second layer 2 is fine, the third layer 3 is medium, and at least the second layer. 2 and the third layer 3, a soil layer 5 provided with an anti-mixing layer 4, a base 10 provided with a ventilation part 14 below a storage part 13 for storing the soil layer 5, and the ventilation part 14 The supply pipe 20 is connected to the filter 21 and the blower 22 interposed in the middle of the supply pipe 20, the drainage device 23 for discharging the water accumulated in the ventilation portion 14, and the drainage from the drainage device 23. A water supply device 30 is provided for storing water in the water storage tank 27 and supplying water from the water storage tank 27 to the plant 35. The plant is planted in the soil layer 5 through a plant support 36, and the plant 35, the soil layer 5, and the ventilation. The air purified by passing through the unit 14 is supplied by the blower 22.
[0024]
As shown in FIG. 2, the soil layer 5 is formed by laminating a first layer 1 made of coarse particles, a second layer 2 made of fine particles, and a third layer 3 made of medium particles from the top. It is.
This is because the layers of the different particle sizes are used in a stacked manner, so that the entire soil layer 5 maintains air permeability and water retention for a long time, maintains and promotes plant growth, and promotes bacterial growth in the soil. This is because the ability to ensure and purify a large amount of air can be secured for a long period of time.
[0025]
The thickness of each layer of the soil layer 5 is preferably 80 to 120 mm for the first layer 1, 180 to 250 mm for the second layer 2, and 150 to 200 mm for the third layer 3.
The thickness of each layer is as described above. The first layer 1 functions to secure the water retention of the entire soil layer 5 and suppress the evaporation of moisture from the surface layer as much as possible. It functions to help absorb nutrients and moisture from the roots of the plant, and the third layer 3 functions to support the soil of the upper two layers 1 and 2 and to ensure air permeability and water retention. This is so that the work of can be fully demonstrated. Furthermore, the first layer 1 and the second layer 2 have a function of helping the plant to root and help the plant itself to become independent, so that a sufficient layer thickness is required.
[0026]
The particle size of each layer is 1.5 to 4 mm for fine particles, 5 to 10 mm for medium particles, and 10 to 15 mm for coarse particles. It is more preferable that the size is 2 to 3 mm, the middle size is 7 to 8 mm, and the coarse size is 10 to 12 mm.
[0027]
This is because if the fine particles are finer than 1.5 mm, sufficient air permeability cannot be ensured. If the fine particles are coarser than 4 mm, the water retention is lacking even if the air permeability is ensured, and the plant roots are dried. It is because it becomes easy to do. This is because if the medium particle is finer than 5 mm and coarser than 10 mm, the particle size is the same as that of the fine particles or coarse particles, and the significance of lamination is lost. If the coarse particles are finer than 11 mm, the water retention of the entire laminated soil is improved, but the air permeability is reduced, and not only is the load applied to the blower 11, but a large amount of air is efficiently contained in the soil layer 5. This is because it is inconvenient that the first layer 1 is likely to be dried if the thickness is less than 15 mm.
[0028]
The material of the soil layer 5 is particularly good as long as it has good air permeability, excellent water retention, uniform particle size, hardly breaks the particle size, develops a soil aggregation phenomenon, and maintains these characteristics for a long time. Although it does not limit, the soil improvement material made from the ceramics which satisfy | fills these characteristics is preferable, and especially the agri stone made from Daiichi Electric Works Co., Ltd. is preferable.
[0029]
As shown in FIG. 2, the admixing prevention layer 4 is made of a nonwoven fabric mixed with ceramics having a particle size of about 10 μm. And it arrange | positions between each layer of the said soil layer 5, and the soil of the particle size of each layer is poured and mixed with the replenished water, and it prevents that the clearance gap between each particle | grain is filled and air permeability is impaired. Moreover, since the ceramic grains are mixed, the mixing prevention layer 4 is prevented from being crushed by the weight of the upper layer soil and impairing the air permeability.
[0030]
An anti-drying layer 6 may be provided on the upper surface of the first layer 1 as shown in FIG. The anti-drying layer 6 is preferably made of a ceramic that is inferior to the first layer in terms of air permeability and water retention, and hydroballs manufactured by Daiichi Denko Co., Ltd. are particularly preferable. The particle size is 10 to 12 mm, and the layer thickness is about 100 to 120 mm. Thereby, evaporation of moisture from the first layer can be suppressed, and evaporation of moisture from the entire soil layer 5 can be further suppressed.
[0031]
As shown in FIG. 3, the base 10 is surrounded by a side wall 11, and a partition wall 12 is formed by arranging a plurality of water-permeable hard resin pipes in the lower intermediate portion, and the storage portion 13 is upward and the lower portion is ventilated.

Anything is acceptable. As the type, herb, Aglaonema, Golden Post, Gold Crest and Silver Star are preferable. These plants 35 are preferably used in combination such as tall, medium and low. By planting plants with different elevations in this way, the air that passes through these plants 35 and is sucked into the soil layer 5 can be efficiently brought into contact with many plants 35, and air purification is further promoted. Is done. In particular, the combination of gold crest and golden post is basically used, and by combining silver star, agraonema and the like, the action of plants such as calming of aroma and stress can be effectively utilized.
[0039]
As shown in FIG. 4, the plant support 36 has an unglazed mortar shape having a large number of through holes 37 formed around it. This is made of unglazed, improves moisture absorption, secures water retention, prevents root drying, and allows roots to grow outside through the through-holes 37. The inside is filled with soil having a particle size of medium or larger so that the can be held upright. And this plant support body 36 is arrange | positioned by the hole opened in the 1st layer 1 and the 2nd layer 2 on the mixing | blending prevention layer 4 on the 3rd layer 3, as shown in FIG.
