According to the present invention there is provided a system for purifying air by drawing air through planter's comprising: a) at least one planter, each planter having a side wall with one or more outlet apertures through which air can pass, and two or more planters being adapted to be connected in row's and/or column/s, b) at least one plenum chamber, each plenum chamber having one or more chamber inlet apertures through which air can pass, each chamber inlet aperture being adapted to connect with a planter outlet aperture, and each plenum chamber having one or more chamber outlet apertures, c) extractor means to draw air through the planter/s, out of the planter's outlet aperture/s into the plenum chamber inlet's and out through a chamber outlet's, in use each planter can be filled with a growing medium and one or more plants, and ambient air is drawn in through the growing medium and the plant roots with the growing medium and plant roots extracting unwanted pollutants or particulate matter in the air, and cleaner air passing through the or each plenum chamber being returned to ambient air from the plenum chamber outlet's.
Preferably two or more plenum chamber are adapted to be connected in rows and/or columns, with one or more chamber outlets of one plenum chamber being connectable to one or more chamber outlets of another plenum chamber to create an air pathway through two or more plenum chambers for cleaner air to be returned to ambient air.
Preferably the planter aperture is in the form of a mesh or sieve to prevent growing medium exiting the planter.
Preferably the means to draw in air through the planter outlet aperture/s into the plenum chamber inlet's and to expel air out of one or more chamber outlets of each plenum chamber is one or more fans and associated diffusers.
Preferably each planter is generally rectangular, with a rectangular base, four side walls, and an open top face, the or each outlet aperture being provided on one side wall. Preferably each planter is of a type described in patent application No GB1901771.4, the contents of which is incorporated by way of this reference. Preferably the planter aperture is provided in the rear side wall described in our co-pending patent application.
Preferably each plenum chamber s generally rectangular with a front face, a rear face and side walls. Preferably the front face supports said chamber inlet/s and is adapted to lie adjacent the side wall of at least one plant box with its inlet's aligning with the planter/s outlet/s. Preferably one or more side walls of the plenum chamber support said chamber outlet/s. Preferably the rear wall supports one or more chamber outlets, in addition to or instead of one or more side walls of the plenum chamber supporting said chamber outlet's.
Preferably any outlet of each chamber can be sealed off by a sealing means or any outlet can be connected by a joining means to the outlet of an adjacent plenum chamber.
Preferably one or more seals are provided to seal any planter outlet to a plenum chamber inlet, or the outlet of one plenum chamber to the outlet of an adjacent plenum chamber.
Preferably a microorganism nhibitor means s provided to remove microorganisms from cleaner air being returned to ambient air. The inhibitor means may be a UV filter or the like.
An embodiment of the invention will now be described with reference to the accompanying drawings in which: Figure 1 shows a perspective view from the rear of a planter Figure 2A shows a perspective view from the front of three plenum chamber n a column, Figure 2B shows a perspective view from the rear of three plenum chamber n a column Figure 3 shows a perspective of three planters in a column connected to three plenum chambers, Figure 4A shows a cross section view of Figure 3 with an air extraction device connected to a side wall of a plenum chamber, and Figure 4B shown a cross section view of Figure 3 with an air extraction device connected to a rear wall of a plenum chamber.
Referring to Figure 1 there is shown a planter 1.
Planter 1 has an open top plant box 10 having a base 11 and two opposing side walls 12,13 and a front and rear side wall I 4, 15. The top face 16 of box 10 is open. Plant box 10 is adapted to receive a growing medium and plants. Front side wall 14 is tapered inwards from the top face of the box to an irrigation box 20. Irrigation box 20 is provided below the open top box 10. Irrigation box 20 is adapted to be filled with irrigation fluid.
A pair of frames 20A,20B are provided either side of the planter 1, said frames providing means to allow one planter to stack above another planter. The frames include projections 21 to engage in recesses 22 of an adjacent frame on another planter. Two or more planters can also be arranged in rows. Thus two or more planters adapted to be connected in row's and/or column/s.
Planter I may be generally identical to that described in patent application No. GBI901771.4 mentioned above. In addition however rear wall 15 includes one or more outlet apertures 15A,15B,15C,15D in the form of a mesh or sieve to allow air to pass whilst at the same time to prevent growing medium exiting the planter.
Referring now to Figure 2, there is shown three plenum chamber 30 arranged as a single column. Plenum chambers 30 are adapted to support three planters 1 arranged in a column. Each plenum chamber 30 is generally rectangular with a front face 31, a rear face 32 and side walls 33,34,35,36. Front face 31 supports a chamber inlet 37, and front face 31 is adapted to lie adjacent the side wall of at least one plant box with its inlet 37 aligning with the planter outlets 15A,15B,15C,15D (see Figure 4). Side walls 33,34,34,36 each support plenum chamber outlets in the form of slots 38.
Seals such as in the form of foam strips 39 surround the chamber inlet 37 to create an airtight seal between a planter outlet and a plenum chamber inlets (see Figure 4).
Two or more plenum chambers 30 are adapted to be connected in rows and/or columns, with one or more chamber outlets of one plenum chamber being connectable to one or more chamber outlets of another plenum chamber to create an air pathway through two or more plenum chambers for cleaner air to be returned to ambient air. The air pathway may pass through and out of each plenum chamber in any direction, e.g. through the top, bottom and/or side of a plenum chamber B. Joining means such as insert 40 can be used for such a purpose. Insert 40 has a rectangular hollow tube 41 with a radially extending central flange 42 supporting foam seals 43. One end of the hollow tube 41 can be inserted into a chamber outlet 38 of one plenum chamber and the other end of the hollow tube 41 can be inserted into the a chamber outlet 38 of another plenum chamber. Flange 42 is sandwiched between two plenum chamber side walls with seals 43 creating an airtight seal between the two plenum chambers.
In addition, sealing means in the form of plugs 45 may be used to seal off any plenum chamber outlet 38. Plug 45 has a projection 46 to enter a chamber outlet 38 and a flange 47 to abut against a plenum chamber side wall and be sealed against it with a seal 48. Alternatively each plenum chamber outlet could be formed when produced with a weakened wall "blank" which can be removed or punched out if it is desired to use any particular chamber outlet. This would obviate the need for plugs 45.
The use of inserts 40 and plugs 45 can create flow paths of air through plenum chambers as required in any array of plenum chambers arranged interconnected in rows and/or columns.
As mentioned above one or more outlet apertures 50 may be provided in each plenum chamber rear wall (in addition to or nstead of one or more side walls of the plenum chamber supporting said chamber outlets) such as shown in Figure 2B, and such outlets could be interconnected using ducting or pipes (see Figure 4B) to deliver clean air to spaces, e.g. through building ventilation systems. In such an arrangement the chamber outlet apertures 38 in the side walls may be sealed off. Apertures 50 may be formed as a blank when each plenum chamber is made and each blank could be punched out when an aperture is required.
Figure 3 shows a perspective view of three planters 1 in a column mounted on three plenum chambers 30 in a column. In practice it is envisaged that an array or wall of numerous numbers of planters and plenum chambers could be arranged in rows and columns with an air patfils created between them using the inserts 40 and plugs 45. Such an array or wall might take complex shapes, e.g. to go around door and window frames on a wall.
Referring now to Figure 4A there is shown a cross section view of three planters 1 each arranged in a column and connected to a plenum chamber 30. Each planter is filled with a growing medium X for plants Y. The outlets 15A of planters 1 are shown abutting against the seals 39 around plenum chamber inlets 37.
Extractor means in the form of a fan 60 is provided to draw air through the planters 1, out of the planters' outlet apertures 15A into the plenum chamber' inlets 37 and out through interconnected chamber outlets 38. Fan 60 is housed above the planters 1 in a housing 61, and clean air s expelled by a diffuser 62 into ambient air which directs the expelled air away from the planters I so that air is circulated around a space.
In use, ambient air is drawn in through the growing medium and the plant roots of each planter 1, with the growing medium and plant roots extracting unwanted pollutants or particulate matter in the air, and cleaner air passing through the plenum chamber being returned to ambient air from the plenum chamber outlets 38.
As shown in Figure 4B, there is shown an alternative arrangement to that shown in Figure 4A. In Figure 4B, instead of air passing into housing 61 from the plenum outlet 38 of the top plenum chamber 30, air is extracted from the outlet 50 in a rear wall of on the middle plenum chamber 30, through a pipe 63, into the housing 61. Pipe 63 may be part of a building ventilation system.
It is envisaged, as mentioned above, that a plurality of plenum chambers and planters can be arranged in row and columns to create a living wall in or outside a building, with the planters and plenum chambers providing a modular construction system.
Although as described in the drawings each planter 1 is connected to a single plenum chamber, it is also envisaged that a plenum chamber could be formed to take more than one planter, e.g. three planters in a row or column.
Instead of the air extraction device such as fan 50 being provided in a separate housing as shown in Figure 4A or 4B, an air extraction device could be provided in a plenum chamber to expel air through an outlet 38 or 50.
The invention may take a form different to that specifically described above.
