The full text of RTO is “Regenerative Thermal Oxidizer”, abbreviated as “RTO”, translated into Chinese as “Regenerative Thermal Oxidizer”, also known as “Regenerative Thermal Incinerator” or “Incinerator”. It is mainly used to control air pollution and achieve clean production.
A device that efficiently burns oven exhaust gas mixed with natural gas to remove harmful volatile organic compounds from the exhaust gas.
It has a significant effect on reducing the concentration of formaldehyde and acetanilide produced in the oven using a thermal storage direct combustion incineration system. The working principle is to directly heat organic waste gas to a high temperature of over 800C for oxidation and decomposition. The high-temperature flue gas generated after oxidation passes through the ceramic material heat storage part. Due to the good heat storage properties of ceramics, the furnace chamber is always maintained at a high working temperature, saving fuel consumption for preheating and heating exhaust gas. The ceramic thermal storage part consists of two or more chambers, and the relatively clean gas after pyrolysis needs to be purged in each chamber before entering the exhaust treatment system or being directly discharged to ensure the removal rate of VOCs.
RTO technology principle:
The principle is to heat the organic waste gas to above 760 degrees Celsius (depending on the composition), so that the VOCs in the waste gas are oxidized and decomposed into carbon dioxide and water. The high-temperature gas generated by oxidation flows through a specially designed ceramic heat storage body, causing the ceramic body to heat up and “store heat”, which is used to preheat the organic waste gas that enters later. Thus saving fuel consumption for exhaust gas heating. Ceramic heat storage chambers should be divided into two or more, with each chamber undergoing a sequence of heat storage, release, and cleaning, and working continuously in a loop. After the “heat release” of the heat storage chamber, an appropriate amount of clean air should be immediately introduced to clean the chamber (to ensure a VOC removal rate of over 98%). Only after the cleaning is completed can the “heat storage” program be entered. Otherwise, the residual VOCs will be discharged into the chimney along with the flue gas, thereby reducing the treatment efficiency.
