Fabrication of Solar Air Purification System

Abstract

Air pollution occurs when harmful or excessive quantities of substances including gases, particles, and biological molecules are introduced into Earth's atmosphere. It may cause diseases, allergies and even death to humans; it may also cause harm to other living organisms such as animals and food crops, and may damage the natural or built environment. Both human activity and natural processes can generate air pollution. Indoor air pollution and poor urban air quality are listed as two of the world’s worst toxic pollution problems in the 2008 Blacksmith Institute World's Worst Polluted Places report. Outdoor air pollution alone causes 2. 1 to 4. 21 million premature deaths annually. According to the 2014 World Health Organization report, air pollution in 2012 caused the deaths of around 7 million people worldwide, an estimate roughly echoed by the International Energy Agency. Though government is taking several measures to control air pollution it is rising rapidly due to urbanization, excessive usage of automobiles, factories, construction works. , etc. , As we cannot deny the fact that development without transport, infrastructure and factories is not possible. We have to search for alternate means of air pollution reduction. However air purification / filtration requires lot of energy to drive induced air fans it is better to use solar energy rather than going for conventional thermal energy. As a part of our project dissertation we are planning to fabricate a solar air purification system for reduction of air pollution.
