Background

A Regenerative Thermal Oxidation (RTO) is a thermal regenerative oxidation furnace (RTO) that oxidizes Organic Substances (VOCs) in exhaust gas into corresponding carbon dioxide and water at high temperature, thereby purifying the exhaust gas and recovering the heat released during the decomposition of the exhaust gas. The RTO main structure comprises a combustion chamber, a regenerative chamber, a switching valve and the like. RTO principle of operation: organic waste gas is preheated by a regenerator, then enters an oxidation chamber, and is heated to about 800 ℃ to oxidize and decompose VOCs in the waste gas into carbon dioxide and water; the oxidized high-heat gas is subjected to heat treatment in another regenerator, and then the flue gas is discharged out of the RTO system. The process is repeated cyclically, each regenerator being switched between modes of feeding exhaust gas and discharging process gas. The switching time can be adjusted according to actual conditions. Because the waste gas contains low-concentration malodorous pollutant organic matters, the waste gas is fully oxidized and decomposed according to the oxidation chamber, the temperature of the smoke gas reaches about 800 ℃, organic components in the waste gas are oxidized and decomposed, then the high-temperature smoke gas enters another group of heat storage chambers to exchange heat with heat storage ceramic fillers, the smoke gas after heat exchange enters a spray washing tower through a draught fan to be washed, and finally the smoke gas reaches the standard and is discharged to the atmosphere through a chimney.
