ELECTRIC CHIMNEY
2012
World's most effective and dangerous pollution is “Air
Pollution”. To Prevent air and control air pollution, I
invented a chimney.
Construction: It consists of a copper wire suspended with
it and an aluminum foil is made to surround it. An
induction coil is made to connect with it. There are two
terminals connected to the induction coil, one is from
aluminum foil and other is from copper wire. This
induction coil will act as a capacitor. When a potential of
20,000 volts is supplied to this circuit, it will create a
field.
Working : Smoke is a colloid of air and carbon. Colloid is
nothing but a dispersed particle dispersed in air medium.
Since, carbon is weightless, it can casily float in air. To
avoid the floating of carbon, we collect the carbon
Particles together. But carbon particle won't adhere with
each other. Because it contains electric charges. We
should remove these charges, to make the carbon particles
together as mass. When the smoke enters into the field,
the charge in the carbon particles are removed. So, the
carbon particles adhere with each other and it
precipitates. So, the pure air is let out from the chimney.
