Definitions
- This invention is related to the subject of the environmental protection. More specifically, it is related to an air treatment apparatus and method.
- Air purification system is one of the most important systems to be installed in building.
- the modern building always included air purification system in the air handling unit of the building during their design, built and construction.
- the air purification system may not powerful enough to handle some special occasions when the pollutants are suddenly increased. For examples, where there is a shop conducting renovation in a shopping centre, high levels of respirable suspended particulates and volatile organic compounds will be generated in that specific shop. If these high level pollutants could not be removed or diminished in a short period of time, the pollutants will be spread to other shops within the shopping centre quickly, through natural ventilation or through the air handling unit of the building, and this will affect the operation of other shops.
- the levels and the type of pollutants are usually specific and heavy and could not be handled by conventional air purifier.
- modification of the conventional air purifier take times to fine tune and it is not feasible to be applied in such a sudden occasion change.
- modifying the internal structure of an air purifier but without having well-fit or tailor-made casing usually lead to a result that the performance of the air purifier cannot be optimized to handle such different environmental condition.
- Air purification system with high flexibility for treating pollutants at different environmental condition is therefore needed.
- the present invention provides a universal system for air purification, which can be applied in different environmental condition.
- the air purification has the characteristics of high mobility, high flexibility and high feasibility in application.
- the internal structure is feasible to be modified in a short period of time by just a few simple procedures (for example, unfasten or un-mount, re-location and re-fasten or re-mount the internal components; addition, subtraction and swapping of the casings within the system Aetc), while at the same time, the filter efficiency and performance can be maintained to be optimum for different air flow rate and/or air flow path after modification for the application in different environmental conditions. It can also be operate in co-ordinate with the blower(s) of different torque within the system to obtain the best performance; even the internal structure is being modified.
- the present invention provides an air purification system comprising: at least one casing;
- the casing of the apparatus are assembled from sheets of board; at least one edge of the sheet of board is joined to another sheet of board with at least a connector;
- At least one casing containing at least one air inlet opening (hereafter named as casing-air-inlet) and at least one air outlet opening (hereafter named as casing-air-outlet); at least one blower with air inlet opening (hereafter named as blower-air-inlet) and at least one air outlet opening (hereafter named as blower-air-outlet); the blower shall be functioned to draw the air to flow from the casing-air-inlet to the casing-air-outlet and to flow within the system; at least one air purifying component; at least one compartment for separating the air from the blower-air-inlet and the air from the blower-air-outlet; the compartment functions purposely to prevent the air from the blower-air-inlet and the air from the blower-air-outlet from being mixed up;

- the opening which serving for air inlet (casing-air-inlet) in one occasion might become an opening serving for air outlet (casing-air-outlet) in another occasion, depending on the positions of the blower and air purifying components within the system in the different occasions when different casing arrangement and sequence is made;
- the blower is flexible for selecting for different speeds and motor torques to overcome the overall static pressure of the air purification system in different occasions. This is because in different occasions due to the different casing arrangement and the positions of the blower and air purifying components within the system, in the different static pressure will be created within the whole air purification system;
- the compartment for separating the air from the blower-air-inlet and the air from the blower-air-outlet prevent the air from the blower-air-inlet and the air from the blower-air-outlet from being mixed up.
- the mixing up of the air from the blower-air-inlet and the air from the blower-air-outlet would decrease the overall efficiency of the air purification system. This is because the overall air volume to be drawn through or to be blown through from the environment to the air purifying component become decreased or diminished, if the air which flow-into and the air which blow-out from the blower and are being mixed up; the sealing of the compartment can be further be enhanced and be improved by using gasket or materials of the similar type and or function.

- At least one edge of the casing is connected to a fitting frame;
- the fitting frame is in form of a narrow strip of metallic extrusion and having a protruded part and a recessed part; the protruded part of the fitting frame of one casing can be easily fastened and unfastened to the recessed part of the fitting frame of another casing.
- mechanical or electronic lock in can further be employed.
- Detachable bottom plate and/or detachable top plate which is/are of the same materials of the casing can be used to cover the most upstream and downstream casing(s) in the air purification systems.
- At least one rack rail is being mounted on the casing, in any direction, but preferabbly parallel to the flow of the air, in comparing to the air flow into the casing-air-inlet, or air flow out from the casing-air-outlet or in comparing to the airflow within the system; in such case, the components such as air purifying components and/or blower is feasible to be adjusted upstream or downstream of each other in a direction parallel to the flow of the air easily to fit for the application in different occasions, without the needed of making a new casing for each different occasions.
- At least one rack rail is being mounted on the casing in a direction that is perpendicular to the flow of the air, in comparing to the air flow into the casing-air-inlet, or air flow out from the casing-air-outlet or in comparing to the airflow within the system.
- the components such as air purifying components (e.g., dust removal filter, HEPA filter, activated carbon filter, zeolite filter, UV germicidal UV lamp, etc) and/or blower is feasible to be adjusted a direction perpendicular or parallel to the flow of the air easily in different occasions according to the environmental condition and indoor air quality.
- the indoor air quality make be obtained by using different types of environmental sensors (for examples, temperature, relative humidity, dust or particulates sensor, carbon dioxide sensor, carbon monoxide sensor, volatile organic compounds sensor, ozone sensor, air flow sensor, radon sensor, bacteria counter sensor, nitrogen oxide sensor , formaldehyde sensor etc).
- Changing the thickness of the air purifying components in a particular section for the air to pass through becomes possible the present invention.

- the performance of the air purification systems can be optimized for different environmental conditions. Such optimization is accompanied by optimizing the flow rate of blower for adapting a particular static pressure and the pressure drop, optimizing the residence time for pollutants to be adsorbed or interacted with the filtering section through this simple air purifying components and internal component rearrangement.
- the rack rail contains multiple mounting holes in any shape, the distance of the mounting holes are with standardized rack unit length for mounting or fastening the blower and/or the air purifying components within the system.
- mounted or fastened blower and/or the air purifying components can also be easily un-mounted or unfastened from the rack(s) and re-mounted or re-fastened to another mounting holes on the rack(s).
- the internal structure and components of the air purification system (for example, the position of the blower and the air purifying components) are therefore easily to be fine-tuned and to be modified within the casing for fitting the needs of different environments.
- Further and additional air purifying components and devices which play the unique role in air filtration and air purification can be added into the casing any time by mounting or fastening them onto the rack(s).
- the neighbor devices can be relocated easily by being un-mounted or unfastened from the rack(s) and being re-mounted or re-fastened to other mounting holes on the rack(s), spacing out more room for the additional items.
- the air purifying components and devices can also be removed anytime from the air purification system without further modifying the casing.
- certain specific and particular air filtration and air purifying components or device can be replaced by another one easily, for the purpose to suit the need of some specific and particular environment. For examples, in a location where particle phase pollutants were in a higher level, a thicker and more powerful particle filter can be used to replace the original thinner and less powerful particle filter.
- the mounting or the fastening of the blower and/or the air purifying components within the apparatus is done by employing of any of the screw, bolt, cage nut, boltless mounting, and hook.
- the blower and/or the air purifying components are mounted onto the rack(s); the mounted or the fastened the blower and/or the air purifying components are easily to be detached, relocated, re-mount or refastening to any position within the apparatus.
- Caster wheel is attached to the bottom of the casing to facilitate the ease of transit between different locations.
- Gasket can be added to the system at appropriate location to prevent the air leakage in the unwanted air flow path.
- the air purification system can be connected to the air duct of the central air handling unit by connecting the casing-air-inlet and/or casing-air-outlet to the air duct of the central air handling unit.
- noise may be produced due to the different internal arrangement of the air purifying components in the whole system, in such case, sponge for absorbing noise can be adhered or put in particular locations within the air purification system, especially near to the where the location of the turbulent flow being created within the system (due to the re-adjustment and/or relocation, addition and or substraction of the internal components of the air purification system), for reducing the noise level.
- the air purification system is universal for different environmental conditions, the outlook of the casing can still be modified simply by putting on different graphic design for fitting the purpose of different environment. For examples, if the system is being used in a shopping mall, advertisement media can be displayed on the casing, and making the air purification system having a broadcasting function in addition to her original air purification functions.
- the power supply can be connected together into one single power supply when the casings are piled up and stacked together.
- the connecting method might by connecting the casing-air-outlet from one air purification system to the casing-air-inlet of another air purification system in a series manner, or in parallel manner, or in the combination of the two manners.
- the connection can be done by employing further casings, or flexible ducting.

SYSTEM AND METHOD OF AIR PURIFICATION
Technical Field
This invention is related to the subject of the environmental protection. More specifically, it is related to an air treatment apparatus and method.
Background
Air purification system is one of the most important systems to be installed in building. The modern building always included air purification system in the air handling unit of the building during their design, built and construction. However, the air purification system may not powerful enough to handle some special occasions when the pollutants are suddenly increased. For examples, where there is a shop conducting renovation in a shopping centre, high levels of respirable suspended particulates and volatile organic compounds will be generated in that specific shop. If these high level pollutants could not be removed or diminished in a short period of time, the pollutants will be spread to other shops within the shopping centre quickly, through natural ventilation or through the air handling unit of the building, and this will affect the operation of other shops.
The levels and the type of pollutants are usually specific and heavy and could not be handled by conventional air purifier. However, modification of the conventional air purifier take times to fine tune and it is not feasible to be applied in such a sudden occasion change. In addition, modifying the internal structure of an air purifier but without having well-fit or tailor-made casing usually lead to a result that the performance of the air purifier cannot be optimized to handle such different environmental condition.
Air purification system with high flexibility for treating pollutants at different environmental condition is therefore needed.
Summary of the Invention
The present invention provides a universal system for air purification, which can be applied in different environmental condition. The air purification has the characteristics of high mobility, high flexibility and high feasibility in application. The internal structure is feasible to be modified in a short period of time by just a few simple procedures (for example, unfasten or un-mount, re-location and re-fasten or re-mount the internal components; addition, subtraction and swapping of the casings within the system Aetc), while at the same time, the filter efficiency and performance can be maintained to be optimum for different air flow rate and/or air flow path after modification for the application in different environmental conditions. It can also be operate in co-ordinate with the blower(s) of different torque within the system to obtain the best performance; even the internal structure is being modified.
To summarize, the present invention provides an air purification system comprising:
at least one casing;
wherein, the casing of the apparatus are assembled from sheets of board; at least one edge of the sheet of board is joined to another sheet of board with at least a connector;
wherein at least one casing containing at least one air inlet opening (hereafter named as casing-air-inlet) and at least one air outlet opening (hereafter named as casing-air-outlet); at least one blower with air inlet opening (hereafter named as blower-air-inlet) and at least one air outlet opening (hereafter named as blower-air-outlet); the blower shall be functioned to draw the air to flow from the casing-air-inlet to the casing-air-outlet and to flow within the system; at least one air purifying component; at least one compartment for separating the air from the blower-air-inlet and the air from the blower-air-outlet; the compartment functions purposely to prevent the air from the blower-air-inlet and the air from the blower-air-outlet from being mixed up;
Further casing(s) is(are) flexible to be added to the air purification system; when more than one casings are employed in the air purification system, the casing(s) within the air purification system is/are flexible to be swapped, to be rearranged, to be subtracted;
The opening which serving for air inlet (casing-air-inlet) in one occasion might become an opening serving for air outlet (casing-air-outlet) in another occasion, depending on the positions of the blower and air purifying components within the system in the different occasions when different casing arrangement and sequence is made;
Preferably, the blower is flexible for selecting for different speeds and motor torques to overcome the overall static pressure of the air purification system in different occasions. This is because in different occasions due to the different casing arrangement and the positions of the blower and air purifying components within the system, in the different static pressure will be created within the whole air purification system;
The compartment for separating the air from the blower-air-inlet and the air from the blower-air-outlet prevent the air from the blower-air-inlet and the air from the blower-air-outlet from being mixed up. The mixing up of the air from the blower-air-inlet and the air from the blower-air-outlet would decrease the overall efficiency of the air purification system. This is because the overall air volume to be drawn through or to be blown through from the environment to the air purifying component become decreased or diminished, if the air which flow-into and the air which blow-out from the blower and are being mixed up; the sealing of the compartment can be further be enhanced and be improved by using gasket or materials of the similar type and or function.
When a blower is installed at the downstream position of the air purification system, where it is in a downstream position of the air purifying components, (in other words, the air from casing-air-inlet is flown to the air purifying component, and then through the blower-air-inlet to the blower-air-outlet), the compartment preferably be, but not limited to, any one of the follow of arrangement:
(1 ) A compartment is an air duct which is being connected directly to the blower-air-outlet and the casing-air-outlet;
(2) A compartment is a panel which is being installed between blower-air-inlet and last the air purifying component in the air purification system, which is upstream of the blower, directing all the air out from the last air purifying component toward the blower-air-inlet;
When a blower is installed at the upstream position of the air purification system, where it is in a upstream position of the air purifying components, (in other words, the air is flown from casing-air-inlet to the blower-air-outlet, and then through the air purifying component), the compartment preferably be, but not limited to, any one of the follow arrangement:
(1 ) A compartment is an air duct which is being connected directly to the blower-air-inlet and the casing-air-inlet;
(2) A compartment is a panel which is being installed between blower-air-outlet and first the air purifying component, in the air purification system, which is downstream of the blower, directing all the air out from the blower-air-outlet toward the first air purifying component;
In any arrangement, it is preferable to have a grid or a frame ware with lattice structure and of appropriate grid size, to be being installed onto the blower-air-inlet and the casing-air-inlet, to prevent any unwanted substance being suck into or get into the blower and damages it.
The air purifying component is any component that is capable to remove and reduce the pollutants from the environment and improve the overall air quality; the said component including, but not limited to the device or component for particle phase and gaseous phase filtration, electrostatic precipitation for particle of any particulates sizes, materials or device for gaseous phase pollutants adsorption, materials or device gaseous phase pollutants absorption, materials or device for catalytic oxidation and/or reduction of volatile organic compounds; bactericide or germicide devices such as UV irradiation at any suitable wavelength.
The said sheets of board preferably to be panel boards, which are made from any single or multiple layers of materials; or plywood sheets of phenolic or with plastic layer; or a metallic layer; or aluminum layer, or galvanized steel, or any plastic layers of different materials, fire-rated materials. Composite of different materials or materials with air gap in between can be applied in order to increase strength and reduce the overall weight of the casing.
The said connector preferably to be metallic extrusion such as zinc, aluminum or similar materials profiles. When assembling together the connector, an overall frame of the casing is made. The sheets of boards are fixed and be reinforced to the connector with the further help of rivets which are being pinned through the connector and the sheets of boards. Special-shape connector such as special L-shape corner connector and form-fitting metal case corners can be used to reinforce the corner edges of the casing.
The connector is in the form narrow strip of metallic extrusion that contains at least two pits along the connector for holding and fixing at least two sheets of board together into a rigid position, wherein the thickness of the pit fit the thicknesses of the board, so that the sheet of board can be firmly hold by the connector. The two pits are preferably perpendicular to each other so that two sheets become right angle to each other after being fixed together with the connector.
At least one casing is assembled by sheets of boards (for example five sheets of boards) to a tub structure with an upper part that is open or can be opened; or the casing is assembling by four
sheets of boards to have both that upper and bottom part that are open or can be opened.
The opening of the tub structure or the opening of the casing being functioned as the casing-air-inlet and/or casing-air-outlet, where the air is being drawn into or blown out from the air purification system through the said opening(s).
At least one sheet of board contains at least one opening on its panel surface, the opening is functioning as the casing-air-inlet and/or the casing-air-outlet, where the air is being drawn into or blown out from the air purification system through the said opening(s).
The casings are allowed to be stacked, and/or to be wholly or partially piled up one on top of the other casing by the fitting frame of the two casings.
At least one edge of the casing is connected to a fitting frame; the fitting frame is in form of a narrow strip of metallic extrusion and having a protruded part and a recessed part; the protruded part of the fitting frame of one casing can be easily fastened and unfastened to the recessed part of the fitting frame of another casing.
To further reinforce and hold the casings into position after being stacked, and/or being partial piled up, and prevent from the casings from being separate by un-authorized user, mechanical or electronic lock in can further be employed.
Detachable bottom plate and/or detachable top plate, which is/are of the same materials of the casing can be used to cover the most upstream and downstream casing(s) in the air purification systems.
At least one rack rail is being mounted on the casing, in any direction, but preferabbly parallel to the flow of the air, in comparing to the air flow into the casing-air-inlet, or air flow out from the casing-air-outlet or in comparing to the airflow within the system; in such case, the components such as air purifying components and/or blower is feasible to be adjusted upstream or downstream of each other in a direction parallel to the flow of the air easily to fit for the application in different occasions, without the needed of making a new casing for each different occasions.
Preferably, at least one rack rail is being mounted on the casing in a direction that is perpendicular to the flow of the air, in comparing to the air flow into the casing-air-inlet, or air flow out from the casing-air-outlet or in comparing to the airflow within the system.
In such case, the components such as air purifying components (e.g., dust removal filter, HEPA filter, activated carbon filter, zeolite filter, UV germicidal UV lamp, etc) and/or blower is feasible to be adjusted a direction perpendicular or parallel to the flow of the air easily in different occasions according to the environmental condition and indoor air quality. The indoor air quality make be obtained by using different types of environmental sensors (for examples, temperature, relative humidity, dust or particulates sensor, carbon dioxide sensor, carbon monoxide sensor, volatile organic compounds sensor, ozone sensor, air flow sensor, radon sensor, bacteria counter sensor, nitrogen oxide sensor , formaldehyde sensor etc).
Changing the thickness of the air purifying components in a particular section for the air to pass
through (and hence modifying the static pressure) becomes possible the present invention. This can be done by adjusting the position of the filters parallel or perpendicular to the flow of air by unfastening or fastening the filter or air purifying components, which are being mounted or fixed-in-position bye the rack rail. By having this feasibility on internal component rearrangement without requiring making a completely new casing, the performance of the air purification systems can be optimized for different environmental conditions. Such optimization is accompanied by optimizing the flow rate of blower for adapting a particular static pressure and the pressure drop, optimizing the residence time for pollutants to be adsorbed or interacted with the filtering section through this simple air purifying components and internal component rearrangement.
More importantly, when making such changes, there is no need to make a new casing or even tailor made another air purification system when being applied to different environment. In another words, all the devices and components in the air purification system are feasibility to be re-employed and without any replacement when being applied in a completely different conditions.
The rack rail contains multiple mounting holes in any shape, the distance of the mounting holes are with standardized rack unit length for mounting or fastening the blower and/or the air purifying components within the system.
Subjected to the indoor air quality of the environment where the air purification system being applied, mounted or fastened blower and/or the air purifying components can also be easily un-mounted or unfastened from the rack(s) and re-mounted or re-fastened to another mounting holes on the rack(s). The internal structure and components of the air purification system, (for example, the position of the blower and the air purifying components) are therefore easily to be fine-tuned and to be modified within the casing for fitting the needs of different environments. Further and additional air purifying components and devices which play the unique role in air filtration and air purification can be added into the casing any time by mounting or fastening them onto the rack(s). If there is not enough space for placing these additional items (the additional air purifying components and devices), the neighbor devices (the original the blower and the air purifying components) can be relocated easily by being un-mounted or unfastened from the rack(s) and being re-mounted or re-fastened to other mounting holes on the rack(s), spacing out more room for the additional items. The air purifying components and devices can also be removed anytime from the air purification system without further modifying the casing. In some occasion, certain specific and particular air filtration and air purifying components or device can be replaced by another one easily, for the purpose to suit the need of some specific and particular environment. For examples, in a location where particle phase pollutants were in a higher level, a thicker and more powerful particle filter can be used to replace the original thinner and less powerful particle filter.
The mounting or the fastening of the blower and/or the air purifying components within the apparatus is done by employing of any of the screw, bolt, cage nut, boltless mounting, and hook. The blower and/or the air purifying components are mounted onto the rack(s); the mounted or the fastened the blower and/or the air purifying components are easily to be detached, relocated, re-mount or refastening to any position within the apparatus.
Caster wheel is attached to the bottom of the casing to facilitate the ease of transit between different locations.
Gasket can be added to the system at appropriate location to prevent the air leakage in the unwanted air flow path.
The air purification system can be connected to the air duct of the central air handling unit by connecting the casing-air-inlet and/or casing-air-outlet to the air duct of the central air handling unit.
In some case, noise may be produced due to the different internal arrangement of the air purifying components in the whole system, in such case, sponge for absorbing noise can be adhered or put in particular locations within the air purification system, especially near to the where the location of the turbulent flow being created within the system (due to the re-adjustment and/or relocation, addition and or substraction of the internal components of the air purification system), for reducing the noise level.
Though the air purification system is universal for different environmental conditions, the outlook of the casing can still be modified simply by putting on different graphic design for fitting the purpose of different environment. For examples, if the system is being used in a shopping mall, advertisement media can be displayed on the casing, and making the air purification system having a broadcasting function in addition to her original air purification functions.
There is individual power supply for each casing in the air purification system. The power supply can be connected together into one single power supply when the casings are piled up and stacked together.
Eventually, a huge air purification system can also be made, by connecting the individual air purification system together. The connecting method might by connecting the casing-air-outlet from one air purification system to the casing-air-inlet of another air purification system in a series manner, or in parallel manner, or in the combination of the two manners. The connection can be done by employing further casings, or flexible ducting.

Detailed Description of the Drawings
Figure 1 indicates one embodiment of the air purification system of the present invention. A detachable bottom plate 108 and a detachable top plate 107 is attached to the most upstream 104 and downstream casing 101 in the system. The air purification system has four casings being piled up in a sequence of 101 , 102, 103 and 104. The bottom plate can be attached to four caster wheel for the ease of mobility.
In another version, the detachable bottom plate 108 can be fixed to the bottom casing, (the upstream casing) 104 into a tub structure. Same to this, the detachable top plate 107 can be fixed to the top casing ( the downstream casing)101 into a tub structure. The two tub structures having their opening being connect to the casings 102 and 103. Casings 102 and 103 are being assembled by four sheets of boards to have both that upper and bottom part that are open or can be opened. The openings 600 serves as the either the casing-air-outlet or casing-air-inlet, which allows the air to be blown out from or blown into the system, depends on the positions of the air purifying components and the blower within the system.
Figure 2 indicates another embodiment of the air purification system of the present invention. It is similar to the embodiment shown in the Figure 1 , but having one more casing 106 being added, in between the casings 103 and 102.
The air purifying components in the casing 106 might be different from or same as the air purifying components in the other casings. With this further casing 106 being added ( and thus the air purifying component), the overall static pressures of the air purifying system become changed. The blower in the air purification system is flexible for selecting for different speeds and motor torques to overcome this enhanced overall static pressure. The blower within the casing where it is residing can be adjusted slightly to operate in coordination with such changed.
Figure 3 indicates another embodiment of the air purification system of the present invention. It is
similar to the embodiment shown in the Figure 1 , but having one casing 103 being removed from the whole system. The overall static pressure of the air purification system becomes lowered. The blower within the casing where it is residing can be adjusted slightly to operate in coordination with such changed.
Figure 4 indicates another embodiment of the air purification system of the present invention. It is similar to the embodiment shown in the Figure 1 , but having the most upstream and downstream casings 104 & 101 being swapped. The original casing-air-inlet becomes the casing-air-outlet 600 (and as so as the original casing-air-outlet becomes the casing-air-inlet).
Figure 5 indicates one embodiment of the present invention. Each of the four sheets of panel board 100 was made to join together by connector 200 and two individual casings 101 and 102 are made. The two casings 101 and 102 have both that upper 500 and bottom part that are open or can be opened, and can be functioned as the casing-air-inlet and/or casing-air-outlet when being applied alone. When connected together by fitting frame 400, the two casings 101 and 102 can be work together and operate in coordination as an air purification system. The fitting frame 400 is in form of a narrow strip of metallic extrusion and having a protruded part and a recessed part; the protruded part of the fitting frame of one casing 101 can be easily fastened and unfastened to the recessed part of the fitting frame of another casing 102. In the casing 102, at least one sheet of board 100 contains at least one opening 600 on its surface; the opening 600 can be functioned as the casing-air-inlet and/or the casing-air-outlet for the air purification system. Special form-fitting metal case corners 300 are used to reinforce the corner edges of each casing. Within the casings 101 and 102, different or same air purifying components and/or blower were attached inside the casings by mounting onto the racks.
Figure 6 indicates a blower 8001 is installed in one of the casings of an air purification system in one embodiment. The casing is assembled from sheets of board 100. A blower 8001 is equipped within the casing. Compartment is assembled purposely to separate the air which flow-into 20 and the air which blow-out from 10 the blower 8001 and prevent them from mixing up. The compartment is assembled from a duct 4001 and a panel board 800 with an opening 900 that fit the duct. The air is drawn from the opening of the casing-air-inlet 900 through the duct 4001 to the blower-air-inlet 8002. It is then blown out from the blower-air-outlet 8003. The air being blown out then filled up the space within the casing, however, it will not be mixed up with the air from the casing-air-inlet. This air is getting out of the casing from the casing-air-outlet 600 in a gentle manner, as a diffuser is installed in the casing-air-outlet 600.
Figure 7 indicates a blower 8001 is installed in one of the casings of an air purification system in one embodiment. The casing is assembled from sheets of board 100. A blower 8001 is equipped within the casing. Compartment is assembled purposely to separate the air which flow-into 20 and the air which blow-out from 10 the blower 8001 and prevent them from mixing up. The compartment is assembled from a duct 8003 which connecting the blower-air-outlet 8003 and the casing-air-outlet 600. The air is drawn into the space within the casing through the bottom opening 500. It is then drawn into the blower-air-inlet 8002. The air being blown out from the blower then exit through the blower-air-outlet 8003, followed by the duct 4002 and then through casing-air-outlet 600 to the environment.
Figure 8 indicates the mounting of the blower onto the racks 700 and 710 within one casing of the air purification system. As indicates, the racks are installed perpendicular 710 to the direction of the air flow (in comparing to the air flow in), or are installed parallel 700 to the direction of the air flow (in comparing to the air flow in). There are multiple mounting holes 705 on the rack, the distance of the mounting holes 705 are with standardized rack unit length for mounting or fastening the blower 8001 and/or the air purifying components within the system.

Compare to that in Figure 8, the blower 8001 is shift lightly upper and more near to the casing-air-outlet by unfasten the blower and re-fasten it on the racks 700 and 710. The position of the blower 8001 is changed without completely making a casing, as conventional air purifier.
Referring to Figure 10 and Figure 11 indicates the front views of the air purification system. The air purification system is built by connecting the several casings 100A, 100B and 100C together. The connecting method is being described and illustrated in the Figure 5. A blower is installed in the casing 100C and drawn the air from to flow through from the upstream to the downstream through the casings in the sequence of 100A, 100B, 100C. The air purifying components illustrated in this embodiment are the filter panels 900 of adsorbent materials which are being arranged in a zigzag manner. The filter panel contains activated carbon and/or zeolite materials in pellet of 3-5 mm diameter and are being hold together and being housed in a rectangular solid container (made by plastic or metal materials), which is permeable to air and allowing the air to pass through its surface (Figure 12 shown the outlook of the filter panel). When the air is passing through the rectangular solid container, it will travel across the adsorbent materials. The pollutants in the air containing volatile organic compounds will be purified and cleaned by the adsorbent materials. The adsorbent materials contain pores to adsorb and absorb the volatile organic compounds and remove them from the air. In term of macro view, the thickness A (in the Figure 10) is thinner in compare to the thickness B (in the Figure 11 ). This is because there are five filter panels 900, (which are being assembled, fixed and mounted onto the rack 710 in the casing for Figure 10), and there are 10 filter panels 900 in the Figure 11. The more compact the filter panel arrangement in the Figure 11 make the whole filtering section becomes thicker, which is more capable to handle harsher and more polluted area. In term of micro view, the distance for air to travel the across the filter panels 900 in Figure 10 is shorter 6001 in compare to that 6002 in Figure 11. The longer traveling distance 6002 mean for a longer residence time for the adsorbing of the volatile organic compound. As a result, the filter panel 900 arrangement in Figure 11 can be employed in heavier polluted area. When moving the air purification system to less polluted area, the filter panels 900 can simply rearranged (by employing less filter and unfasten the original panel filter from the rack 710; re-fasten them and rearranging the inclining angle of the filter panels 900 as illustrated in Figure 10) without re-constructing the whole air purification system. Thus, the present invention illustrated a universal air purification system fitting for different environmental conditions.
Figure 13 and Figure 14A and Figure 14B illustrates the front views an air purification of the same
casings sequence being used in different occasions. The air purification system is built by connecting the several casings 100A, 100B, 100C and 100D together. The connecting method is being described and illustrated in the Figure 5. A blower is installed in the casing 100D and drawn the air from to flow through from the upstream to the downstream through the casings in the sequence of 100A, 100B, 100C and 100D. 100C house the particulate filtering air purifying component for particle removal. Casing 100C house the filter panels 900 of adsorbent materials which are being arranged in a zigzag manner. The filter panel contains activated carbon and/or zeolite materials in pellet of 3-5 mm diameter and are being hold together and being housed in a rectangular solid container (made by plastic or metal materials), which is permeable to air and allowing the air to pass through its surface (Figure 12 shown the outlook of the filter panel). When the air is passing through the rectangular solid container, it will travel across the adsorbent materials. The pollutants in the air containing volatile organic compounds will be purified and cleaned by the adsorbent materials. The adsorbent materials contain pores to adsorb and absorb the volatile organic compounds and remove them from the air. The blower is installed in the middle of the air purification system. However, when being use in another occasion (Figure 14A and Figure 14B) where there is some modification on the air purifying component (a valve 950) is being installed. The blower is shift lightly to the left so that to make the air distribution more even when it is traveling within the air purification (during the open and close of the valve). Air quality sensor is installed in the system. When the particulate level of the environment is too high, the valve 600 will be turn to the open position (as illustrated in Figure 14A) to allow all air to by-pass the filter panels 900. All the air draw into the system will have the particulate removal at the first priority, and protest the filter panel 900 from contaminated by the unfiltered particulates (as the particulate filter in casing 100D might not be 100% effective on particulate removal) . When the concentration of the particulate of the environment reached to a satisfactory level, the valve 6003 will be closed (as illustrated in Figure 14B). All air will be force to pass through the filter panels 900. The filter panels then carry out their function for VOC removal.
Figure 15 indicates an example of the outlook design of one embodiment. The air go into the system through the opening 901 and exist at the opening 902
Figure 16 indicates an example of the outlook design of one embodiment, this embodiment is the same as the one as shown in the Figure 15. However, the casing is re-orientated so that it is 90 degree turned. The upper and lower casings are changed as well. The air flow direction is is modified so that the air go into the system through the opening 901 , and exist at the opening 902.
Figure 17 indicates an example of the outlook design of one embodiment. The stack up of an extra unit lead to the embodiment shown in Figure 18.
The present invention is illustrated above through the examples and said embodiment. It will be appreciated by persons skilled in the art that numerous variations and/or modifications may be made to the invention as shown in the specific embodiments without departing from the scope or spirit of the invention as broadly described. The present embodiments are, therefore, to be considered in all respects illustrative and not restrictive.
