Natural - Windblown dust, wildfires and volcanos.
The Air pollutants has severe impact on human body and the Environment.
To understand the source of Air Pollutants, the cause of fire needs to be understood. Different devices/Machines using fuel to combust produces air pollutions. For combustion, fire is required and the fire comprises of 4 components:
1. Oxygen
2. Fuel
3. Ignition
4. Chemical Reaction
To effectively combust the fuel, one must achieve stoichiometric condition which leads to reduction of Air Pollutants. Assuring each devise/Machine adhering to the norms for effective combustion of fuel is impractical and thus an external system is required to arrest these air pollutants to protect the environment.
Many conventional air pollution filtration systems are available using different methods of arresting the pollutants.
Indian Patent Application 202017033757 discloses a system comprising series of filters enclosed within a chamber having plurality of orifices to allow the smoke to enter and absorb at least one pollutant by one filter. The invention has a limitation of arresting one pollutant at each stage which increases the complexity of the system in order to operate and maintain the system.
Indian Patent Application 202221034063 discloses an embodiment comprising an Inlet to suck the air inside the system with the help of a blower motor, a processing unit to treat the sucked air using lime solution and an outlet to release the purified air in the ambiance.
The disadvantages of above-mentioned prior arts include formation of harmful chemicals, limitation in scaling, higher installation errors leading to smoke leakages and residue causing landfills.
The inventor of present invention has developed a system for eliminating the air pollutants like CO, CO2, SO2, total particulate matter and odour. The invention has varied uses to control air pollution and reduce carbon footprint. It can be installed at various locations and can be connected to machineries emitting smoke. The system acts as a filter to put immediate control on air pollution. The present invention is economical, easy to install, Scalable and easy to maintain.
The making and use of various embodiments of the present invention are discussed in detail below and the present invention provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed herein are merely illustrative of specific ways to make and use the invention and do not delimit the scope of the invention.

In a preferred embodiment, the conductive plate (9) is positively charged by said an electric unit means (12) through a contact member (10) providing terminal connectivity of positive electric charge. Preferably, said electrical unit means (12) is provided with led indicator, earth pin and fuse.
In further preferred embodiment, neutralizer (13) contains of pallets of CaCO3 and activated carbon. Its structure is depicted in Figure 5.

The mechanism is simplified and fool-proof to ensure that any unskilled operator can also be able to operate and fix it.
One electric unit means (12) can be used to connect almost five air pollution filtration assemblies.
In accordance one of important embodiment of the present invention, the method of working of said system (1) is explained below:
The air from the outer environment/ machine exhaust is received in first air processing chamber (2) through one or more air inlet window(s) (1) with the help of exhaust fan(s) (14). The received air is held in said first air processing chamber (2), and heated above the dew point of SO2 using heating element (3) and passed smoothly to the second air processing chamber (15) through one or more air exit window(s) (6). The temperature above the dew point of SO2 reduce H2O content in the air and hot air rises above which pulls the air from external environment and air flow starts. The heater also helps to not to reach the dew point of certain flue gases like SO2. The air processing chamber’s
volume is dependent on the volume of air pulled out of environment. The metal plate (16) negatively charge the components of the air.
The pollutants molecules breaks/ disintegrate. The carbon molecules and tar stick to the inner wall of the air pollution filtration chamber (5) as well as the plate (16) and (9). While Oxygen gets released to the air. The deposited carbon on the air pollution filtration chamber (5) and the plates can be scraped easily. The scraping can be done regularly for effective performance of the unit. As the air is heated at the first air processing chamber (2) the deposit on the inner wall of the filtration chamber has less water vapours and SO2 is released to wards neutralizer (13).
The neutralizer preferably has a combination of 2 components CaCO3 and activated carbon.
The SO2 from the air gets reacted with CaCO3
SO2 + CaCO3 CO2 + CaSO3
And CO2 released from the reaction gets arrested by activated carbon. The activated carbon also helps in arresting volatile organic compounds, Methane and odour.
Thus, releasing clear air in the environment.
Inventive subject matter of the present invention provides a system and method for reducing pollutants, harmful gases and odour.
Getting oxygen released through such activity is itself an advantage. The elimination of the CO, CO2, SO2, tar and total particulate matter is achieved which is the major concern across the globe.
The present invention is further described with the help of the following examples, which are given by way of illustration purpose only and therefore should not be construed to limit the scope of the invention in any manner.
Example 1: Working and performance of system as disclosed in present invention: The air pollution filtration system (100) was constructed as per below mentioned specifications and installed at the pollution generating location and smoke release were analysed by Flue Gas Analysis Method.
The chemical properties of exit gas with respect to the structural and functional arrangement of system. Results are tabulated in table 1 and 2
Table No. 1
Table No. 2
The present invention provide a simple, scalable and low maintenance system for filtering the air pollutants. This system can be fixed at the exhaust of the machineries emitting the smoke in order to reduce the air pollution. It can also be installed in open spaces, rooms or auditoriums.
