Description

The present invention relates to a green wall air purification equipment having a function of cleaning the features and the atmosphere for greening wall.

  The wall surface greening air purification apparatus has an advantage that greening and air cleaning can be performed efficiently without taking up a large floor area because the wall surface serving as an elevation performs greening and air cleaning. Conventionally, in this type of wall surface greening air purification device, wall surfaces are greened by arranging a plurality of boxes in which plants are planted on the front side so as to be adjacent to each other, and the air to be purified sucked by a fan is passed through a duct. In this way, it is fed to the back of each box. The to-be-purified air sent in is purified by passing through a plant growth base such as a soil layer filling each box.

Japanese Patent No. 5001148

The configuration of the conventional example described above has the following problems.
・ A large number of ducts are required to send the air to be purified to each box to be the greening part.
・ In order to push the air to be purified discharged from the duct evenly into the box, a separate rear panel for dispersion is required on the back side of the box.
・ The duct is exposed from the box and deteriorates over time, and maintenance of the duct becomes necessary.
-The duct space for the duct may be larger than the box that will be the greening part, so it cannot be installed close to the wall.

In addition, there are the following problems regarding the blowing of the air to be purified.
(1) Since the pressure loss when the air to be purified passes through a plant growth base such as soil is large, a large fan is required for blowing air.
(2) Use of a large fan may increase noise.
(3) Since it is necessary to send the air to be purified to the entire plant growth base, a fan with a large air flow rate is required even if the pollutant concentration of the air to be purified is low.
(4) When the soil of the plant growth base is reduced over time and a space is formed in the upper part, the air to be purified escapes from the upper part.
(5) Since wind comes out from the entire front surface, it is necessary to consider the installation location.

The purpose of this invention is to reduce the duct for feeding the purified air, or can be eliminated, without requiring a large fan for blowing, providing a green wall air purification equipment which can suppress the noise That is.

The wall surface greening air purification apparatus of this invention has a plant growth base on which a plant is planted on one side, and a ventilation layer forming member formed with a ventilation layer along the other side of the plant growth base, A highly breathable soil portion having a breathable member interposed between the ventilation layer, penetrating between both surfaces in the plant growth base, and having a ventilation resistance in a penetrating direction smaller than other portions of the plant growth base; The basic structure of the highly breathable soil portion is that the outer periphery is partitioned by a partition material and is filled with a plant growth base material .

  According to this configuration, the ventilation layer forming member that forms the ventilation layer along the plant growth base is provided, and the ventilation layer and the plant growth base are partitioned by the breathable member, so that the number of ducts for sending the air to be purified is reduced. Or can be eliminated. Since the air to be purified diffuses throughout the back surface of the plant growth base in the ventilation layer, it is not necessary to provide a separate panel or the like for dispersion on the back surface side. Since the ventilation layer is provided over the entire back of the plant growth base, it can be sufficiently ventilated even if it is thin. Even if the ventilation layer is provided, the overall thickness of the wall greening air purification device does not become too thick. . Thus, the ventilation layer can be made thin, and it is not necessary to make a large piping space for the duct on the back surface. When the purified air is sent to the ventilation layer from a duct communicating with the end face of the ventilation layer, or directly from the fan installed in this wall greening air purification device to the ventilation layer Can install this wall greening air purification device in close contact with the wall surface, and can further reduce the protruding width from the wall surface.

Moreover, the following points are improved by providing a highly air-permeable soil part penetrating between both surfaces in the plant growth base and having a ventilation resistance in the penetration direction smaller than that of other parts.
(1) Pressure loss of the air to be purified when passing through the plant growth base can be suppressed, and the fan can be downsized.
(2) Noise can be suppressed by using a small fan.
(3) Since the location and number of highly permeable soil sections can be set arbitrarily, the optimal fan should be selected according to the atmospheric pollutant concentration, ventilation volume, etc. You can choose.
(4) Since the location where the wind comes out is determined in advance by the location of the highly breathable soil portion, even if a space is created above the plant growth base, the air to be purified does not escape from there.
(5) Since the place where the wind comes out can be arbitrarily set by appropriately setting the arrangement place of the highly breathable soil part, it is easy to install the wall greening air purification device without the wind coming out affecting people.

In this invention, you may use the plant growth base material with a particle size coarser than the plant growth base material which comprises the said other part of the said plant growth base for the said high air permeability soil part.
Thereby, ventilation resistance can be made smaller than the other part of a plant growth base, using a highly breathable soil part for the growth of a plant, utilizing a highly breathable soil part.

In this invention, the partition material may be a material that has air permeability but cannot pass through the plant growth base material that constitutes the other part of the plant growth base.
By making a partition material into the said material, it can prevent that the plant growth base material around a highly air-permeable soil part enters into a highly airy soil part.

In this invention, you may provide the said high air permeability soil part in the multiple places in the said plant growth base.
According to the installation place of the wall surface greening air purification apparatus, the highly air-permeable soil part can be provided in arbitrary plural places.

In this invention, the highly air permeable soil part is a ventilation unit in which the plant growth base material is filled in a bag-like body made of the tubular partition material and an air permeable end face material that closes both ends of the partition material. It may be.
In this case, a highly breathable soil part can be easily provided in the plant growth base.

(A) is the longitudinal cross-sectional view of the wall surface greening air purification apparatus concerning another proposal example , (B) is the elements on larger scale.

An example of a proposal which is the basis of the present invention will be described with reference to FIGS. As shown in the longitudinal sectional view of FIG. 1, the wall surface greening air purification apparatus 1 includes a plant growth base 2 such as a soil layer in which a plant 30 is planted on one side, and a ventilation layer along the other side of the plant growth base 2. 3 is a wall panel shape having a ventilation layer forming member 4 in which 3 is formed. The one side of the plant growth base 2 is a greening portion. Between the plant growth base 2 and the ventilation layer 3, a mesh material 5 which is a kind of a breathable member is interposed. One side on which the plant 30 of the plant growth base 2 is planted is also covered with another mesh material 15.

  The plant growth base 2 occupies most of the plant growth base 2 and has a plurality of through holes 6 penetrating between both surfaces, and a high air permeability provided in the through holes 6. It consists of soil part 2b. The plant growth soil portion 2a becomes the substantial plant growth base 2 on which the plant 30 is planted. The mesh members 5 and 15 are made of, for example, a wire mesh obtained by knitting plated wires vertically and horizontally, and have a perforated shape that covers only the surface of the plant growth soil portion 2a of the plant growth base 2.

  For example, lightweight soil is used as the plant growth base material A of the plant growth soil portion 2a. Specifically, in addition to natural soil, various commonly distributed materials such as organic soil improvement materials such as bark compost, peat moss and cocoa dust, or inorganic soil improvement materials such as perlite and vermiculite are appropriately combined. It may be used. Further, it may be a sponge-like or felt-like material having air permeability. In addition, ceramic or the like may be used.

  As the plant growth base material B of the highly breathable soil portion 2b, a material having a coarser particle diameter than the plant growth base material A of the plant growth soil portion 2a, for example, a soil base material such as perlite, is used. Therefore, the air permeability resistance in the length direction of the through-hole 6 is smaller in the highly breathable soil portion 2b than in the plant growing soil portion 2a.

  The outer periphery over the plant growth base 2 and the ventilation layer 3 is surrounded by a rectangular outer peripheral frame 7. The ventilation layer forming member 4 has a thin box shape including a portion 7a having a thickness of the ventilation layer 3 in the outer frame 7 and a back plate 8 covering an opening portion of the outer frame 7 opposite to the plant growth base 2. Has been. The ventilation layer 3 is communicated with a fan 9 installed outside the apparatus via a duct 10. In the example shown in the figure, the duct 10 is connected to the back surface of the air-permeable layer 3, but it may be communicated with the side end surface, the upper and lower surfaces, etc. of the air-permeable layer 3.

  An example of the size of the wall surface greening air purification device 1 will be described. FIG. 3 shows a state in which the plant growth base materials A and B are removed. The total thickness (depth) D is 200 mm, the thickness d of the ventilation layer 3 is 50 mm, and the height H is 2250 mm. The width (not shown) is, for example, an integral multiple of 1/2 of a building module, and is 445 mm to 1820 mm. In addition, this dimension example is an example and what is necessary is just to design arbitrarily.

  For example, a ventilation unit 20 shown in FIG. 4 is used for the highly breathable soil portion 2b of the plant growth base 2. The ventilation unit 20 has a plant growth base material B (inside a bag-like body 21 made of a mesh material composed of a tubular partition member 21a and end surface members 21b and 21c on the front side and the back side that close both ends of the partition member 21a. (Not shown). In the example of the figure, the outer shape of the bag-like body 21 is a cylindrical shape, but may be a prismatic shape or other shapes. The size of the ventilation unit 20 is not limited to this, although the diameter E is about 90 mm and the length L is about 150 mm when the outer shape is cylindrical.

  The partition member 21a needs water permeability, but air permeability is not always necessary, and it is preferable. The end face materials 21b and 21c are preferably excellent in air permeability. The material of the partition member 21a and the end face materials 21b and 21c is, for example, made of resin, plant natural material, metal, or the like.

  The partition material 21 a has a coarseness that prevents the surrounding plant growth base material A from entering the bag-like body 21. However, it is not necessary to restrict the root of the plant 30 planted in the plant growing soil portion 2a to extend to the highly air-permeable soil portion 2b. Further, the roughness of the end face materials 21b and 21c is such that the internal plant growth base material B does not leak to the outside and does not prevent the wind from passing through. Specifically, when the particle diameter of the plant growth base material B to be filled is relatively coarse (5 mm or more), the partition material 21a has a coarseness of about 1 to 2 mm, and the end face materials 21b and 21c have a coarseness. The length is about 3 mm.

  If this ventilation unit 20 is used, the highly air-permeable soil part 2b can be easily provided in the plant growth base 2. For example, as shown in FIG. 5, the diameter of the end face material 21b on the front side is made larger than the diameter of the partition member 21a, so that the ventilation unit can be inserted into the hole 15a provided in the mesh material 15 on the front side from the front side. By inserting 20, the outer peripheral edge 21 ba of the end face material 21 b on the front surface side is engaged with the mesh material 15, and the ventilation unit 20 is fixed to the mesh material 15.

  Further, as shown in FIG. 6, a support plate 22 having both ends supported by the outer peripheral frame 7 may be provided inside the plant growth base 2, and the support plate 22 may support the ventilation unit 20. It is desirable that the support plate 22 has a mesh shape that does not hinder root elongation. As shown in FIG. 7, the ventilation unit 20 may be supported by a plurality of support bars 23 instead of the support plate 22.

  The highly breathable soil portion 2b may or may not be planted. When planting, it is desirable to plant plants that prefer dry and drained soil. In order not to make the highly breathable soil part 2b inconspicuous when not planted, a plant in which stems and leaves tend to extend around the highly breathable soil part 2b in the plant growing soil part 2a. 30 should be planted.

  For example, as shown in a longitudinal sectional view in FIG. 2, the wall surface greening air purification device 1 is disposed along the wall surface 31 of the building so that one side where the plant 30 of the plant growth base 2 is planted is the front surface. It is attached to the wall surface 31 via the support member 32. By attaching in this way, greening of the wall surface 31 is achieved by the plant 30 planted on one side of the plant growth base 2. Further, by operating the fan 9 (FIG. 1), the air to be purified outside the apparatus is sucked by the fan 9 and sent into the ventilation layer 3 through the duct 10. The air sent in is purified by passing through the plant growth base 2. By providing the highly permeable soil portion 2b on the plant growth base 2, the amount of air sent in can be increased compared to the case where the highly permeable soil portion 2b is not provided. Can be purified.

  According to the wall surface greening air purification device 1 having this configuration, the ventilation layer formation that forms the plant growth base 2 in which the plant 30 is planted on one side and the ventilation layer 3 along the other side of the plant growth base 2 in this way. Since the mesh material 5 is interposed between the plant growth base 2 and the ventilation layer 3, the ventilation layer 3 is simply communicated with the fan 9 outside the apparatus by a single duct 10. Thus, the air to be purified sucked by the fan 9 can be introduced into the ventilation layer 3 and can be spread over the whole area of the plant growth base 2. Accordingly, since the duct 10 for sending the air to be purified can be minimized, the piping space of the duct 10 can be reduced as much as possible, and the wall surface greening air purification apparatus 1 can be installed substantially in contact with the wall surface 31 of the building. Maintenance is almost unnecessary. When the duct 10 communicates with the ventilation layer 3 at the side end face of the wall surface greening air purification device 1, it is possible to install the duct 10 in close contact with the wall surface 31 of the building.

  Moreover, the air to be purified when passing through the plant growth base 2 is provided by penetrating between both surfaces in the plant growth base 2 and providing a highly breathable soil portion 2b having a smaller ventilation resistance than the plant growth soil portion 2a. The pressure loss can be suppressed. As a result, the fan 9 can be downsized. By using the small fan 9, noise can be suppressed. Since the location and number of the highly breathable soil portions 2b can be set arbitrarily, the optimum fan 9 is selected according to the concentration of air pollutants, the amount of ventilation, etc. at the location where the wall greening air purification device 1 is installed. You can choose.

  Since the location where the wind comes out is determined in advance by the location of the highly breathable soil portion 2b, even if there is a space above the plant growth base 2 due to the loss of the plant growth base material A, the air to be purified can escape from there. Absent. Most of the purified air goes out from the location of the highly breathable soil portion 2b. Therefore, the location where the wind comes out can be arbitrarily set, and the wall greening air purification device 1 can be easily installed without the wind coming out affecting people.

  Furthermore, since the highly breathable soil part 2b has good drainage, it is useful for draining the plant growth base 2. In particular, when the highly air-permeable soil part 2b is arranged at the lower part of the plant growth base 2, the drainage effect is even higher. Since the static pressure is lowered by promoting the drainage of the plant growth base 2, the strength of the outer peripheral frame 7, which is a constituent material of the wall surface greening air purification device 1, can be lowered. Thereby, weight saving and cost saving can be achieved.

FIG. 8 shows a longitudinal sectional view of another proposed example . In this proposed example , a wall surface greening air purification system 11 is configured by arranging a plurality of the wall surface greening air purification devices 1 so as to be in contact with each other at their end faces. Here, the two wall surface greening air purification apparatuses 1 are arranged vertically. Each outer peripheral frame 7 which is an end surface where the upper and lower wall surface greening air purification apparatuses 1 and 1 are in contact with each other is provided with a communication port 12 that allows the ventilation layer 3 to communicate with each other. The fan 9 installed outside the apparatus communicates with the ventilation layer 3 of one wall surface greening air purification device 1 (here, the upper wall surface greening air purification device 1) through one duct 10. As a result, the air to be purified sucked by the fan 9 enters the ventilation layer 3 of the one wall surface greening air purification device 1 from the duct 10 and further through the communication port 12 to the ventilation layer 3 of the other wall surface greening air purification device 1. It is sent in. The effect by each wall surface greening air purification apparatus 1 is the same as that of the proposal example shown in FIG.

  In this way, by constructing the wall surface greening air purification system 11, by arranging a plurality of wall greening air purification devices 1 of the same standard, the greening of the wall surface several times the wall area carried by one wall surface greening air purification device 1 And air purification.

FIG. 9 shows a front view of still another proposed example . In this proposed example , one wall greening air purification device 1 in which the plant-growing soil portion 2a of the plant growth base 2 is divided into nine sections by the vertical and horizontal intra-compartment soil support material 24, and the plant-growing soil section 2a The other wall surface greening air purification apparatus 1 divided into three sections by the support member 24 is installed side by side. One highly breathable soil portion 2b is provided in each section. In each wall surface greening air purification device 1, each section communicates with a back surface air-permeable layer 3 (not shown in FIG. 9). The intra-compartment soil support material 24 is made of, for example, a mesh material. By interposing the intra-compartment soil support material 24, the plant growth base material A of the plant growth soil portion 2a can be evenly dispersed in the occupied space of the plant growth soil portion 2a without any bias.

The two wall surface greening air purification apparatuses 1 and 1 are provided with communication ports 12 (not shown in FIG. 9) similar to the example of FIG. The ventilation layers 3 are blocked from each other by being partitioned by 13. In this case, the ventilation layer 3 for each wall greening air purification device 1 communicates with a fan 9 (not shown in FIG. 9) outside the device via an individual duct 10 (not shown in FIG. 9). It is. In each wall greening air purification device 1, the air to be purified reaches all the sections of the plant growth base 2 through the ventilation layer 3. The effect by each wall surface greening air purification apparatus 1 is the same as that of the proposal example shown in FIG.

Also in this proposal example , one wall surface greening air purification system 11 is made to communicate with the ventilation layer 3 of two adjacent wall surface greening air purification apparatuses 1 and 1 through the communication port 12 as in the embodiment of FIG. It may be configured. In this way, the ventilation layer 3 is made continuous so that it can be ventilated both vertically and horizontally, and can be restricted by the partition plate 13.

FIG. 10 shows a longitudinal sectional view of still another proposed example . In this proposed example , in the wall greening air purification device 1 shown in FIG. 1, among the sections divided by the soil support material 24 in the section of the plant growth base 2, some of the sections are empty sections 14 not filled with soil. It is what. One highly permeable soil portion 2b is provided in each of the sections that are not empty sections 14. A sealing plate 16 is provided in a portion of the mesh material 5 that serves as a partition material with the ventilation layer 3 in the empty compartment 14, whereby the air to be purified introduced into the ventilation layer 3 passes through the empty compartment 14 from the mesh material 5. It is prevented from leaking outside. Thus, by making a part of the section that becomes the plant growth base 2 into the empty section 14, a part of the greening part can be made into a non-greening part, for example, by combining the greening part and the non-greening part, A green wall with a mosaic pattern. In addition, you may provide the water receptacle (not shown) which is located in the vicinity of the upper end in the empty division 14, and opposes the lower surface of the soil support material 24 in an division.

Of these sections, the three lowest sections are the empty sections 14 provided with the fans 9. The fan 9 in each empty section 14 is configured to send the air to be purified into the ventilation layer 3 corresponding to the plant growth base 2 for three sections arranged vertically on the fan 9. That is, the air-permeable layer 3 provided along the plant growth base 2 is divided into three areas by a partition plate (not shown) or the like, with three vertically arranged sections as one area.

If the thickness dimension of the air-permeable layer 3 is 50 mm, the air-permeable layer 3 can bear a greening area (area of the plant growth base 2) of up to about 10 m ^{2 with} respect to one fan 9, so that it is arranged vertically as described above. If the total area of the three sections is about 10 m ^2, it can be adequately handled. In other words, since an arbitrary greening area can be borne according to the scale of the fan 9, it can be handled within the arbitrary greening area. A power supply control panel 17 that controls all three fans 9 is provided in the central empty section 14 among the empty sections 14. Further, a water receiving portion 18 is provided on the upper side of each empty section 14. Other configurations and operational effects are the same as those of the embodiment of FIG.
