RTO是指蓄熱式熱氧化技(jì)術(shù)，其原理是把有機(jī)廢氣加熱到(dào)760攝氏度以上(shàng)，使VOCs氧化分解成二氧化碳和水(shuǐ)。氧化産生(shēng)的高(gāo)溫氣體流經特制的陶瓷蓄熱體，使陶瓷體升溫而蓄熱，此“蓄熱”用于預熱後續進入的有機(jī)廢氣，從(cóng)而節省廢氣升溫的燃料消耗。陶瓷蓄熱體分成兩個(gè)及以上(shàng)的區或室，每個(gè)蓄熱室依次經曆蓄熱-放(fàng)熱-清掃等程序，周而複始，連續工(gōng)作。蓄熱室“放(fàng)熱”後立即引入部分已處理合格的潔淨排氣對蓄熱室進行清掃（以保證VOCs去除率在95%以上(shàng)），“清掃”完成後才能(néng)進入蓄熱程序。

(1) Process Introduction
RTO refers to regenerative thermal oxidation technology, which heats organic waste gas above 760 degrees Celsius to oxidize and decompose VOCs 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. This "heat storage" is used to preheat the subsequent organic waste gas, thereby saving fuel consumption for exhaust gas heating. The ceramic heat storage body is divided into two or more zones or chambers, and each chamber undergoes the procedures of heat storage, heat release, and cleaning in sequence, repeating the cycle and working continuously. After the heat storage chamber releases heat, a portion of the treated and qualified clean exhaust gas is immediately introduced to clean the chamber (to ensure a VOCs removal rate of over 95%). Only after the "cleaning" is completed can the heat storage program be entered. Widely used domestically and internationally for the treatment of oven exhaust gas in painting processes, as well as for similar exhaust gas treatment in chemical and electronic industries. Applicable waste gas: medium to low concentration 100-3500mg/m3, with a decomposition efficiency of 95%~99%.

(2) Technological advantages
① Almost all waste gases containing organic compounds can be treated;
② The elasticity of handling organic waste gas flow is high (20-120% of nominal flow);
③ Can adapt to changes and fluctuations in the composition and concentration of VOC in organic waste gas;
④ Not sensitive to small amounts of dust and solid particles carried in the exhaust gas;
⑤ High thermal efficiency (>95%) among all thermal combustion purification methods;
⑥ Under appropriate exhaust gas concentration conditions, self heating operation can be achieved without the need to add auxiliary fuel;
⑦ Low maintenance workload, safe and reliable operation;
⑧ Organic sediment can be periodically removed, and the heat storage body can be replaced;
⑨ The pressure loss of the entire device is small and the service life is long.
