Making Ozone Use safer In India – We value life

Designing a Safe vent ozone distructor

Ozone distructors have compromised design if they

1) are not designed for the flow of water flow and capacity of the contact tank

2) If catalysts are used and they are not sized appropriately. They need sufficient surface area , sufficient particle size and sufficient air velocity to work efficiently. A manufacturer of these catalyst will tell you all about this

3) they do not incorporate a moisture separator if required by design of contact tank

4) They do not take care of temperature control

Vent ozone distructors for SS tanks: These are for smaller applications where the capacity of the ozone contact tanks vary from 3 KL to 30 KL total capacity. It is normal to incorporate in the design of these contact tanks off gas vent that facilitates tank breathing during filling and emptying. The size of these vents is in accordance to the capacity of the contact tank.   the contact tanks vents have to be correctly designed , else there could be an implosion of the contact tank .

Vent ozone distructors are of 2 types .The thermal ozone distructors utilize heat to destroy ozone.  The temperature that has to be reached for 100% ozone destruction within a few seconds would be as high as above 250-350 Deg cel . This is very challenging as the surface of the distructor gets extremely hot and effective control of the temperature rise assumes importance. The power requirement will be sometimes more than the power required for the ozone production.  Thermal type vent distructors are not very common for small applications and are very difficult to source. Few reputed companies manufacture larger thermal type but they are very expensive and high on operation costs

The catalytic ozone distructors are most common and very reliable if designed well

They are easy to install, operate and maintain. operate and maintain. They contain specialized catalyst that have proven record of destroying ozone . These catalyst lasts a long time  ( 3-4 years) if the ozone distructors  are designed well.

Catalysts used in vent ozone distructors have to be used carefully. They are poisonous and so the design and the installation of the vent ozone distructor should prevent this catalyst of falling into the tank when they crumble. Moisture from the ozone tank can clog these catalysts, and prevent tank breathing, causing implosion of ozone contact tanks. The ozone distructor design must prevent crumbling and clogging of the catalyst, enable free tank breathing.

These are small steps we at OTSIL take to make ozone use safer in India . Contact us for well designed ozone distructors . Be safe .
