适用于小风量、高浓度、高温的有机废气处理
Suitable for treatment of organic waste gas with small air volume, high concentration and high temperature

系统简介 System introduction
RTO系统采用天然气助燃,将小风量、高浓度的有机废气直接焚烧,在750~850℃的高温状态下,有机物会分解成无害的CO2和H2O,同时放出大量热量,化学反应方程式如下:
Using natural gas to assist in combustion, RTO system incinerate organic waste gas with low air volume and high concentration directly. At 750~850℃, the organic matter will be decomposed into harmless CO2 and H2O, and a large amount of heat will be released at the same time. The chemical reaction equation is as follows:

At 750~850℃, the organic matter will be decomposed into harmless CO2 and H2O, and a large amount of heat will be released at the same time. The chemical reaction equation is as follows:

经燃烧后的高温烟气(≥800℃)通过蓄热陶瓷后,热量被贮存在蓄热陶瓷中用于预热新进的有机废气,烟气温度被大大降低后达标排放,最终排烟温度只比进口废气温度高40℃;
After combustion, the high temperature flue gas (≥ 800 ℃) passes through the regenerative ceramics. The heat is stored in the regenerative ceramics for preheating the new organic waste gas. The flue gas temperature is greatly reduced and the final exhaust gas temperature is only 40℃ higher than the imported waste gas temperature.

第一次循环(如上图分为三个蓄热室A、B、C):First cycle (see the above chart divided into three regenerative chambers A, B, C):
蓄热室C: 有机废气经引风机进入蓄热室C的陶瓷蓄热体(陶瓷蓄热体“贮存”了上一循环的热量,处于高温状态),此时,陶瓷蓄热体释放热量,温度降低,而有机废气吸收热量,温度升高,废气经过蓄热室C换热后以较高的温度进入氧化室;
Regenerative chamber C: Ceramic regenerator for organic waste gas entering regenerator C through induced draft fan Ceramic regenerator of organic waste Gas entering Regenerator C through induced Fan (Ceramic regenerator "stores" the heat of the previous cycle and is in a high temperature state). At this time, ceramic regenerator releases heat and decreases the temperature. The organic waste gas absorbs the heat, the temperature rises, the exhaust gas enters the oxidation chamber at a higher temperature after heat transfer in the regenerative chamber C;

氧 化 室:经过陶瓷蓄热室C换热后的有机废气以较高的温度进入氧化室反应,使有机物氧化分解成无害的CO2和H2O,如废气的温度未达到氧化温度,则由燃烧器直接加热补偿至氧化温度,由于废气已在蓄热室C预热,进入氧化室只需稍微加热便可达到氧化温度(如果废气浓度足够高,氧化时可以不需要天然气加热,靠有机物氧化分解放出的热量便可以维持自燃),氧化后的高温气体经过陶瓷蓄热体A排出;
Oxidation chamber: The organic exhaust gas after heat transfer in the ceramic regenerator C enters the oxidation chamber at a higher temperature. The organic matter is oxidized and decomposed into harmless CO2 and H2O. If the temperature of the exhaust gas does not reach the oxidation temperature, it is compensated by direct heating of the burner to the oxidation temperature. Since the exhaust gas has been preheated in regenerator C, the oxidation temperature can be reached by heating slightly into the oxidation chamber(If the concentration of exhaust gas is high enough, natural gas heating may not be needed during oxidation, and the heat released by the oxidation decomposition of organic matter can maintain spontaneous combustion.). The high temperature gas after oxidation is discharged through ceramic regenerator A.

蓄热室A: 氧化后的高温气体进入蓄热室A(此时陶瓷处于温度较低状态),高温气体释放大量热量给蓄热陶瓷A,气体降温,而陶瓷蓄热室A吸收大量热量后升温贮存(用于下一个循环预热有机废气),经风机作用气体由烟囱排入大气,排气温度比进气温度高约40℃左右;
Regenerator A: The oxidized high temperature gas enters regenerator A (when the ceramic is in a low temperature state), the high temperature gas releases a large amount of heat to regenerator A to cool the gas, while the ceramic regenerator A absorbs a large amount of heat and then warms up and stores it (for the next cycle of preheating organic waste gas). The gas is discharged into the atmosphere by a fan, and the exhaust temperature is about 40℃ higher than the intake temperature.

第二次循环:废气由蓄热室A进入,则由蓄热室B排出,蓄热室C进行反吹清扫;
The second cycle: exhaust gas enters from regenerator A, then discharges from regenerator B, and regenerator C is blown back and cleaned.

第三次循环:废气由蓄热室B进入,则由蓄热室C排出,蓄热室A进行反吹清扫;
The third cycle: when the exhaust gas enters the regenerator B, it is discharged from the regenerator C, and the regenerator A is cleaned by back blowing.
