Regenerative Technology of Oxidization (RTO) Overview
Regenerative Technology of Oxidization mainly adopts the new ceramic heat-storage material, and by being combined with an advanced heat exchange design and technology, it reduces heat loss by a large amount. It can be used to treat organic exhaust gases with a concentration between 500～4000 mg/Nm3 of any substance, and the pollutant concentration which it can handle can be as high as 10000mg/Nm3; when the pollutant concentration reaches about 2000mg/Nm3, the equipment can maintain combustion by relying on its own hear at a rate higher than 5000Nm3/h. It is especially suitable to process organic exhaust gases with corrosive substances or substances toxic to the catalyst, as well as circumstances that require high-temperature oxidation or have stench.
Processing Principle
The regenerative oxidization equipment includes the following major parts: regenerative heat-storage towers, combustion chamber equipped with a combustor system and ventilation system equipped with a valve and fan. Its principle is to use the ceramic heat-storage body to store the heat generated by the decomposition of the organic gases, and then use the heat stored by the ceramic heat-storage body to decompose the organic gases that have not decomposed; in this way, VOC in the exhaust gas will be oxidized into CO2 and H2O in the oxidizing chamber, which will achieve great heat efficiency. The oxidization temperature is usually around 810~980 ℃, the chosen residence time is generally around 0.3～0.5S, and the oxidation conversion rates of ester, ether and aldehyde are all above 90%.
