Ozonators produce Ozone using air, which has 21% of Oxygen as feed gas. Air should be free of dust, oil, moisture for efficient conversion. Generally Drier is used to obtain purified Air. Oxygen gas can be used for higher yields of Ozone.
Corona Discharge Ozonator.
This produces more quantity of Ozone compared to other methods. This Equipment operates on the principle of Corona discharge ( CD) which takes place at high potential between two electrodes separated by dielectric medium and constant Air gap. CD is identified by typical hissing sound. When purified Air passes through CD, part of oxygen is converted to Ozone. Ozone has a characteristic foul smell which does not last more than 20 mins ( after which Ozone gets converted to Oxygen again) . The pressure of feed should be less than 1kg/sq.cm.
UV Bulb Ozonator: This employs a special UV Bulb housed in a chamber through which feed gas ( air/ Oxygen) is passed. The bulb products UV light at a wavelength capable of splitting Oxygen atom to form Ozone.
Operational Details: Typical schematic is as illustrated,. Compressed Air after drying is fed to the Ozonator. Output Ozone is injected through Venturi fitted with NRV. Ozone dissolves in the partial flow through Venturi & Later thoroughly mixed with main stream flow. Ozone can also be bubbled through a porous diffuser. The bubble raises through the column, ensuring thorough mixing of Ozone. A good recirculation in either case ensures complete missing.
