Ozone Generation From corona

Abstract


The phenomenon of violet glow, hissing noise and the production of
ozone gas in the overhead transmission line known as corona is used in our project
for the production of ozone gas. The gas produce out of the device can be used for
the treatments of drinking water disinfections and air purification.
The device has a discharge tube in which high electric field is applied so
as to breakdown the ozone present in the air. This phenomenon occurs at field
strength of about 25 KV at normal room temperature. This unit employs a high
voltage of 30 KV peak at a frequency of 15 KHZ to 20 KHZ. Such a high Voltage is
developed by means of Line output transformer or Fly-Back Transformer.
The amount of Ozone output can also be controlled indirectly by varying
the A.C input voltage by using a tap-changing transformer.
Ozonation is 3125 times more powerful than chlorination. The unit can treat 5 liters
of impure water in about 2 minutes. The nascent oxygen makes ozone a very
powerful disinfecting agent. Ozone destroys all bacteria by cell lycing.
This project is also provided with simple protection circuit, which
prevents the MOSFET from being damaged, by High voltage spikes and low voltage
surges. The unit can be continuously operated for four to six without much heating
of the power electronic devices.
