FIELD OF INVENTION
[001] The present invention relates to air pollution control tower for controlling air pollution in a predetermined space such as vehicles, kitchens, rooms and polluted industrial areas etc. The invention, in particular, relates to a system and a method to reduce the air pollution at various traffic junctions where the pollution is at maximum level particulate matter such as PM2.5, PM10, Co, sox, and Nox emissions. Also, this invention treat the air pollution in effective manner by sucking and treating the air pollutants.
BACKGROUND OF THE INVENTION
[002] Considering the day to day pollution in traffic junction due to congestion and subsequent polluted gas exhaust ( i.e. Idle engine pollutes 2-3 times more as compared to normal running engine), the below project model is helpful. In India around 70-80% people are exposed to open air during the travel time directly (scooter, vehicle, cycle, foot path etc.) and the excessive inhalation creates Lung and Bronchitis diseases such as cancer. Also the offices, Buildings, schools available nearer to the traffic junction faces unhealthier situations. When the traffic Jam, the engine starts to eject more pollutants along with unburnt particles. Also the city /road construction develops a lot of dust particles and particulate matter (PM2.5 and PM10) which directly floats in atmosphere and inhaled by the human body.
[003] For example undesirable levels of nitrogen oxides are also sometimes encountered inside buildings and outside buildings. Thus, it is desirable to reduce or control these and other forms of pollution from the air. Further, such humidity control has generally not provided optimum humidity levels for extended periods of time over varying temperatures. Medical experience indicates, for example, that a majority of

the persons suffering from arthritis have less discomfort if they are able to remain for extended periods of time in an atmosphere with a humidity level in the range of from about 35% to about 55%.
[004] Presently there is no effective tower type pollution control system exist in India to clean all the threat measured for air pollutions in single multi operated and controlled manner with respect to the various pollution situations as per requirements. Existing prior arts such as “IN201941009550A” describes about hybrid pollution control system for foundry shops. This shows the exhausted flue gas treatment of foundry shops. In this the particulate matter decomposition method, sucking method, best operating process to suit the particular condition based environmental threats is not disclosed. Also, the process of dealing the various open floating gases is not described. Another prior art “IN201921000779A” describes about an automatic pollution sensor with multimedia system. This system comprises means for detection of pollutants data and treatments of air pollution is not disclosed. Another prior art “IN201821045610A” describes about detection and indication with alarm about the pollution. Also, another prior art “IN201811021516A” describes about clean air through distilled water and by magnetic region. However this air purification system doesn’t suit the efficiency in large scale requirement with smog-Fog and humidity. Even though operation is continuous, but does not suit the requirement.
[005] Existing prior art “US589269A1” discloses an environment monitoring system and method works systematically and continuously monitoring an environment and it is programmed to systematically collect environment data for a site. In “US3870781” air pollution control system treats the SO2 releases from Kiln as flue gas by scrubbing method with help of Limestone. In “US4676299” describes about method to prevent air pollution from the particulate and gaseous pollutants. Using the process, in the thermal power plant exhausted SO2 is treated by pebbled bed. However the above

mentioned process and method are either restrictive to specific environment and air pollutants.
[006] US3699750A titled “Air pollution control apparatus” discusses about large upright casing, with a plurality of elongated air-pervious bags extending vertically within the casing, each air bag having its lower end fixed to a partition plate in line with an opening in the latter and its upper end closed and fixed to a grid frame. Dust-laden air is caused to flow upwardly through the air bags, the dust being filtered from the air and remaining within the bags and the dust-free air passing into the casing for exhaust through a casing outlet. The grid frame is spring-supported and means are provided to vibrate the grid frame and consequently the air bags suspended from the grid frame. This vibration is performed at a time when dust-laden air is not being admitted to the casing inlet, and is for the purpose of shaking the dust particles from the interior of the air bags. The air bags are disposed in two groups with a space therebetween large enough to accommodate a person for the purpose of inspecting the condition of the air bags.
[007] US3670477A titled “Sludge retrieval apparatus for air pollution control systems” discusses about apparatus for removing pollutants from pollutant-laden water discharged from a water type dust collector device, such polluted water being pumped from a collecting tank, where the pollutants are held in solution in the water by a mixer, to a water-using device, such as a foundry sand muller, which does not require pollution-free water and which, by its nature of operation, that is, when the pollutant-laden water is passed through the sand, effects removal of pollutants from the water thus discharging the water in a cleaner state than when it entered the muller.
[008] US5606495A titled “Device for controlling air pollution” relates to Process and device are provided for controlling air pollution. The apparatus includes electrochemical, electro thermal and humidity sensors which sense the presence of

selected polluting gases and activate an electronic circuitry which controls the release of oxygen, fresh air, or perfumed air and thereby dilutes the concentration of polluting gases within a selected space.
OBJECTS OF THE INVENTION
[009] It is therefore a principal object of the present invention to reduce the air pollution at traffic junctions where the maximum pollution appears due to vehicle idle with CO, SOX, NOx emission and PM2.5 /PM10.
[0010] It is another object of the present invention to propose a system/ method to treat air pollution in most effective way to reduce the pollution impact on human beings.
[0011] These and other objects and advantages of the present subject matter will be apparent to a person skilled in the art after consideration of the following detailed description taken into consideration with accompanying drawings in which preferred embodiments of the present subject matter are illustrated.

In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system

having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
