The present invention generally relates to a field of cleaning systems. More particularly, the present invention relates to a system and a method for filtering pollutants from the air.
Air streams carry contaminant material therein. In many instances, it is desired to filter some or all of the contaminant material from the air stream. For example, gas flow streams to engines (for example combustion air) for motorized vehicles or for power generation equipment, gas streams to gas turbine systems and air streams to various combustion furnaces, carry particulate contaminant therein that should be filtered. A variety of air filter arrangements have been developed for contaminant rejection.
The suction blower carries dust particles through suction and releases to the atmosphere thereby, creating air pollution. To irradicate the issues of air pollution the filters are designed for checking air pollution.
US9964078B2 discloses about a filter assembly for a motor-vehicle air cleaner may include a main filter, an auxiliary filter set apart from the main filter, and a filter mount fixed to and supporting the main filter and the auxiliary filter. In an example embodiment, the filter mount is fit table in and removable from a housing of the air cleaner, and includes a sealing element passing between the main filter and the auxiliary filter.
US8721756B2 discloses about the filter of the invention is a cartridge filter comprising a structure that can maintain a filter medium in an air stream to filter particulates to protect a gas turbine power system. The filter combines a mechanically adequate filter structure and an effective filter medium for to obtain a useful system.
The above-mentioned prior arts are efficient in removing a particular type of pollutant and exposes other pollutant to the atmosphere.
In order to overcome the above mentioned limitation, there exists a need to develop a system with multiple filters for filtering out a wide variety of pollutant present in the air.
The technical advancements disclosed by the present invention overcomes the limitations and disadvantages of existing and convention systems and methods.
The present invention generally relates to a system for filtration of air.
An object of the present invention is to provide a system for reducing air pollution.
Another object of the present invention is to provide a system using a renewable source of energy.
Another object of the present invention is to provide a system for removing harmful pollutant such as carbon monoxide and nitrogen oxide.
According to an aspect of the present disclosure, the system comprises of a blower, a first filtration layer, a second filtration layer, a third filtration layer, a fourth filtration layer and a solar panel.
The first filtration layer is enclosing at least partially on an outer surface of a blower for removal of at least a first pollutant entering the blower, wherein the first pollutant is a particulate matter of size ranging below 1 micron.
The first filtration layer is a HEPA filter belonging to a category of air filters which employ fiberglass filter mats to mechanically remove airborne particulates, such as pollen, smoke, dust, and bio contaminants, from within the work environment.
When the blower component of the filtration system passes air through the HEPA filter, particulates adhere to or become embedded within the fibers. Additionally, particles passing through the filter collide with the gas contained within, which slows the velocity and increases the chance of becoming adhered to or embedded in the filter.
The second filtration layer is covering at least partially an outer surface of the first filtration layer for filtering out a second pollutant comprising oxide of nitrogen and hydrocarbon present in air.
The second filtration layer is a Catalytic reactor, also referred to as selective catalytic reduction (SCR) module, are air pollution control module widely used to mitigate nitrogen oxide (NOx) emissions produced by the burning of fossil fuels in industrial applications. These modules first inject ammonia into the industrial exhaust and emissions, which reacts with the NOx compounds to produce nitrogen and oxygen.
The three-way catalytic converter in a car's exhaust system is used to reduce the amounts of NOx, CO, and other VOCs in the engine emissions.
The third filtration layer is enclosing at least partially an outer surface of the second filtration layer for filtering out a third pollutant comprising of carbon monoxide from the air penetrating through the second filtration layer.
The third filtration layer is an activated carbon having special properties that allow the layer to remove volatile organic compounds (VOCs)
Each carbon filter is typically given a micron rating that specifies the size of particle which the filter removes from a fluid. Typical particle sizes which can be removed by carbon filters range from 0.5-50 pm. The efficacy of a carbon filter depends not only on the particle size, but also on the rate of flow of fluid through the filter.
The fourth filtration layer is enclosing at least partially an outer surface the third filtration layer forming an outermost layer of the filtration system for filtration of a fourth pollutant comprising of dust and carbon dioxide gas entering the filter.
The fourth filtration layer is a mesh or a scrubber. The industrial air scrubbers employ a physical process of scrubbing which removes particulates and gases from industrial emissions, such as smokestack exhaust, before they are released into the atmosphere. There are two main categories of scrubbers-dry scrubbers and wet scrubbers.
The air filtration is powered by a power source. The power source is a solar energy source comprising of the solar panel for capturing solar energy and a converter for converting the solar energy into electrical signals.
The different layers of the air filter overlap each other in a sequence to form a cylindrical structure with the fourth filtration layer forming the boundary of the air filter.
However, the shape of the structure may vary according to the arrangement of the filter.
According to an embodiment, the method comprises of:
The first step discloses about removing of at least a first pollutant from a blower using a first filtration layer enclosing at least partially on an outer surface of the blower, wherein the first pollutant is a particulate matter of size ranging below 1 micron.
The second step discloses about filtering out a second pollutant comprising oxide of nitrogen and hydrocarbon present in air using a second filtration layer covering at least partially an outer surface of the first filtration layer.
The third step discloses about filtering out a third pollutant comprising of carbon monoxide from the air penetrating through the second filtration layer using a third filtration layer enclosing at least partially an outer surface of the second filtration layer.
The fourth Step discloses about filtering a fourth pollutant comprising of dust and carbon dioxide gas entering the filter using a fourth filtration layer enclosing at least partially an outer surface the third filtration layer forming an outermost layer of the filtration system.
According to an aspect of the present disclosure, a plurality of layers overlapping each other above the blower. The first filtration layer is marked as layer 1 comprising of a HEPA filter for filtering out particulate matter of PM 2.5 and below 1 micron. The first filtration layer surrounds the outer circumference of the blower by the sidewalls.
The second filtration layer comprises of the catalytic reactors for removing oxides of nitrogen/ hydrocarbon. The second filtration layer covers the outer circumference of the first filtration layer either partially or completely.
The third filtration layer comprises of the fine activated carbon for filtering carbon monoxide from the air. The third layer completely or partially surrounds the second filtration layer.
The fourth filtration layer comprises of fine steel mesh or scrubber for scrubbing out dust and carbon dioxide from the air. The fine steel mesh or scrubber forms the outer most layer of the filter.
The filtration layers are arranged such that the blades of the blower are exposed and surrounded partially by the sidewalls. The layers form a pair of semi-circles that are further connected together with the help of clamps.
The air filter is connected to the solar panel for receiving energy. The solar panel receives solar energy from the sunrays and converts the energy into electrical signals for generating power. The power is stored in a batter for future use.
According to an alternate embodiment, other renewable sources of power may be used in the system for supplying power to the system.
