Rotating RTO
Rotating RTO workflow The core of rotary RTO is the heat storage body, combustion chamber, and rotary valve, and its workflow is based on the cycle of "heat storage oxidation heat release": Waste gas preheating: Organic waste gas enters the heat storage body (usually ceramic material) through a rotary valve, and is heated to near oxidation temperature (about 760-850 ℃) by the previously stored heat. High temperature oxidation: The preheated exhaust gas enters the combustion chamber and is heated to the set oxidation temperature by the combustion of auxiliary fuels (such as natural gas). Organic pollutants (VOCs) are oxidized and decomposed into CO ₂ and H ₂ O, releasing a large amount of heat. Heat recovery: The purified high-temperature gas flows through another part of the heat storage body, transfers heat to the heat storage body, and is discharged at a lower temperature (usually 50-100 ℃ higher than the intake temperature). Rotation switching: By continuously rotating the rotary valve (usually at a speed of 0.5-2 revolutions per minute), the thermal storage body continuously switches between intake, exhaust, and purge states, achieving the recycling of heat and continuous treatment of exhaust gas.
Core strengths Extremely high thermal efficiency The continuous switching of the rotary valve greatly improves the utilization rate of the thermal storage body, with a thermal efficiency of up to 90% -97%, far higher than the traditional two chamber RTO (80% -85%), and significantly reduces auxiliary fuel consumption. Large and stable processing capacity A single device can handle air volumes ranging from thousands of m ³/h to hundreds of thousands of m ³/h, suitable for high concentration and high air volume exhaust gases; The rotation switching method reduces airflow impact and ensures more stable operation. High pollutant removal rate In a high-temperature oxidation environment (≥ 760 ℃) combined with sufficient residence time (≥ 1 second), the removal rate of VOCs can reach over 99%, meeting strict environmental emission standards. compact footprint Adopting a concentric circle or multi sector thermal storage design, the structure is compact, and compared to other RTOs with the same processing capacity (such as three chamber RTOs), the footprint is reduced by 30% -50%. Easy to operate and low maintenance cost The rotary valve is the core moving component, with a relatively simple structure and low failure rate; Automated control
制系统可实现无人值守，运维成本低于传统 RTO。 Rotating RTO has become one of the mainstream equipment for VOCs treatment due to its efficient heat recovery, stable processing capacity, and excellent purification effect, especially suitable for industrial scenarios with high requirements for energy consumption, footprint, and treatment efficiency. Its core advantages lie in "high efficiency and energy saving+high removal rate+compact design", making it an ideal choice for balancing environmental standards and operating costs. Economic analysis of operational cases Anhui XX New Material Manufacturing Factory has the following production data: Waste gas components: ethyl acetate, toluene. Silicon free Exhaust gas temperature: 70 ℃. In summary, our company is currently designing a set of 30000m3/hr RTO equipment.
