Air Pollution & the consequent Global Warming
MOST URGENT ISSUES TODAY…

Our Idea…Our
Approach…
PURIFYING CHIMNEY EXHAUST SO AS TO
REDUCE AIR POLLUTION AND CONSEQUENT GLOBAL WARMING
OUR IDEA…OUR APPROACH…
• POLLUTION AND GLOBAL WARMING
EXHAUST FROM CHIMNEYS
•REDUCTION IN AIR POLLUTION & RELATED CONCERNS
REDUCTION IN THE QUANTITY OF EXHAUST
COMPONENTS OF CHIMNEY EXHAUST :
PERCENTAGE OF SPECIFIC TOXINS IN AN AVERAGE CHIMNEY EXHAUST
CO & CO2SO2NO & NO2WATER VAPOURDUST PARTICLESOTHERS
THE APPARATUS :
Filtering Chamber 1
Filtering chamber 2
Filtering chamber 3
FILTERING CHAMBER 1(FC1)
FILTERING CHAMBER 2(FC2)
Layout : FC2 comprises of chemical solutions and reagents aligned in
a proper manner. It has 3 sections so as to absorb much of the harmful gases.
DESCRIPTION :
SO2 + NaOH ---- Na2SO4 + H20
SECTION 1 :
CO2 + Ca(OH)2 ---- CaCO3 + H2O
SECTION 2 :
2NO2 + 3H2 ----2NH3 + H2O
SECTION 3:
FILTERING CHAMBER 3(FC3)
Exhaust’s temperature is reduced.
Dust and soot is filtered
Toxic gases treated.
OVERALL IMPACT :
EFFECTIVENESS AND PRECISION
Is economical, efficient and stable.
Works silently without interrupting the normal running of the chimney.
Easily installed adjacent to an existing chimney with few structural changes.
