How to Design an Ozone Destructor
Ozone is a gas with strong oxidizing properties. It is widely used in water treatment, air disinfection and sterilization, medical fields, and food industries. Ozone can be obtained through ozone generators, corona treatment and plasma discharge can also produce ozone. However, high concentrations of ozone can corrode equipments and harm human health, so it is very necessary to deal with residual ozone.
How to design an ozone destruction system? An ozone destructor usually consists of a tank, a catalyst bed, a fan, and a heater (if necessary). When designing, we should follow the following principles:
1) All ozone gas must pass through the ozone decomposition catalyst bed.
2) The gas should flow from top to bottom.
3) The tank should be made of stainless steel to prevent ozone corrosion.
4) At room temperature, the humidity of the gas should not exceed 80%. If exceeds 80%, the gas temperature needs to be moderately increased according to the ozone concentration, usually above 70℃. During the decomposition process of ozone, heat is released. The concentration of ozone is closely related to the extent of temperature increase, so it is necessary to measure the temperature after the temperature increase.
5) The catalyst is supported by a filter screen to facilitate the passage of gas.
6) The amount of ozone decomposition catalyst used is related to the gas flow and ozone concentration. After confirming the reasonable GHSV(h-1), the required amount can be calculated.
