Ozone Extraction

09/26/2010 6:25 AM

In our site there is corona treatment test for LLDPE. so In that process It generate ozone gas.IT is 2kW corona plant. Our extraction unit is not working properly.then we design a suction inlet and blower which is impeller made out of Aluminium alloys. But with time it corrode..

I am planning to design a ozone precipitation unit. It is rather than filter. I am planning to outlet head sink on the water gallon which circulate the water inside the system. Chemically ozone react with water and air flow is free from ozone.

I am planning to try it.is it work or not? If there is other implementation and improvement greatly appreciated.

With regard

Water immersion does not remove the OZONE efficiently by reaction with water. This will need a long dwelling time in the region of 30 minutes...

In the first place, use S.S. material if the Aluminium is corroding too quickly in your experience. You can dilute the air containing the Ozone by sucking some extra clean air, and reduce the concentration. This will also reduce the corrosion. As long as you are sucking the Ozone generated you are OK to suck from another area surrounding the Ozone area.

Otherwise, get some specialised filters using some catalytic converter technology to destroy the Ozone.

Ozone does not react (much) with pure water. It reacts with the dearth floating in the water. You can use dirty water and clean it up at the same time...

Ammoniac in the water will destroy the ozone. It might cause other problems though.

Dry Ozone Removal – CARULITE® 200 (Hopcalite Type Catalyst) pellets is used on an industrial scale in water treatment plants to destroy the ozone residual from the contact chamber. All you need is a blower to suck the ozone through a bed of catalyst. Here is the link.

Thermal destruction works well. A few seconds at 400C does it. Heat also promote the corrosion of the contact surfaces. Stainless steel last many years but eventually fails.

Giving grate contribution to the person who need it strongly is greatly appreciated by me. Thanks buddies..

Now I design a ozone extraction system as well as distraction unit. I suppose to do it by using fine bubbler diffuser. I diffuse ozone mix air flow to the effluent water in the factory which is stored at the tank. I believe that water mixture mixing because of air bubbles. Then Air mixture passed through the charcoal filter. I think this cause to reduce ozone level by 50%.

I am going to try it in next week. so If there is any suggestions for the system is greatly appriciated...

Thanks again..

With regards,

Asitha
