Description:
FIELD OF THE DISCLOSURE
[0001] This invention generally relates to a field of air purification devices and systems, and more specifically relates to an ambient air purification device configured to improving outdoor air quality in an efficient and effective manner, by purifying outdoor polluted ambient air at an overall lower operational cost.

BACKGROUND
[0002] The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.
[0003] “Air Pollution” is a major issue in India and globally. Many of the Indian cities consistently rank as some of the most polluted in the world. According to the World Air Quality Report 2020, 22 out of 30 most polluted cities in the world are in India. Apart from affecting investment climate, crop yield, the rising levels of air pollution also affects life expectancy of the people to a great extent. In Delhi, for example, a city infamous for its severe air pollution, this reduction could be as high as 11.9 years. Therefore, controlling ambient air pollution in cities is important and must be done. The constantly increasing levels of air pollution have been a global challenge for decades. With ongoing population growth, urbanization and industrialization increasing, this trend seems to be irreversible. According to World Health Organization (WHO), 91 percent of the world’s population live in places where air pollution levels exceed WHO guidelines. Sources like traffic and industry cause high concentrations of particulate matter and nitrogen oxide (NO2). In high traffic areas or places with large emissions and low air exchange, the exposure is especially high and the effect on human health is harmful. This applies, for example, to busy streets and traffic hubs. The danger is even greater in underground rail stations, where rail abrasion generates metal-bearing particulate matter. People with respiratory illness, the elderly or children should not be exposed to high concentrations of particulate matter or NO2.
[0004] There have been many outdoor air purification systems and devices developed in recent past to refresh the stale air, by eliminating several types of air pollutants. One of the outdoor air purification system is a “High-Efficiency Particulate Air (HEPA) Filter” installed by governments at ambient locations in few cities, to control ambient air pollution at destination by way of air filtration. The HEPA Filter is most important component of any air purifier and it is effective. However, a major drawback of using the HEPA filter is that the HEPA filter is non-effective in long run, as the HEPA filter becomes clogged within 3-6 months. Further, the HEPA filter needs to be replaced regularly with new filters which is not cost-effective as most of the HEPA filters are imported. Furthermore, the HEPA filter is non-biodegradable and causes downstream pollution at waste fills, which clearly implies that the HEPA filter is not environment friendly. Furthermore, the HEPA filter is not able to treat PM2.5 and PM 10.0 and other harmful elements in an effective and sustainable way, and that too at lower cost. Another method of the air purification system is by using an “Electrostatic Air Cleaner” which is able to remove dusts, soot, and ash particles from normal air. The electrostatic air cleaner uses electrostatic forces to pull these particles from the air. Each dust, soot, or ash particle has mass. The air exerts two types of forces on the particles, the buoyant force and the viscous drag force. Since the particles are denser than air, the buoyant force alone cannot support the particles. The viscous drag force keeps the particles from descending quickly. For small particles the terminal velocity can be lower than 1 mm/s. The drag force opposes relative motion between the particles and the air, and moving air tends to carry the particles along with it. The slightest upward breeze can keep the dust, soot, and ash particles aloft. However, a major drawback of using the electrostatic air cleaners is that these air cleaners are not sustainable as the pollution can come back (specially in an ambient environment) as soon as the charge goes off or dust is again kicked due to footfall. The dust comes back to the atmosphere again proving “Electrostatic or ION based Air Cleaner” non effective for ambient atmosphere.
[0005] Hence, in view of the above, there is a need for an environment friendly, sustainable, cost effective, thoroughly designed, and effective ambient air purification system or device which solves the aforementioned drawbacks by handling PM2.5, PM10.0, and other harmful gaseous elements like CO, NOx and others in order to provide clean air and healthy environment, thereby minimizing a lot of health-related issues and provide clean air outdoors, or at least provide a suitable alternative.
