RTO是把有机废气加热到760摄氏度以上,使废气中的VOCs在氧化分解成二氧化碳和水。氧化产生的高温气体流经特制的陶瓷蓄热体,使陶瓷体升温而“蓄热”,此“蓄热”用于预热后续进入的有机废气,从而节省废气升温的燃料消耗。陶瓷蓄热体应分成三个(含三个)以上的区或室,每个蓄热室依次经历蓄热-放热-清扫等程序,周而复始,连续工作。
RTO is to heat the organic waste gas to 760 ℃ and decompose VOCs into carbon dioxide and water. The high-temperature gas produced by oxidation flows through a special ceramic regenerator to make the ceramic body warm up and "heat storage". This "heat storage" is used to preheat the organic waste gas which is subsequently entered, so as to save the fuel consumption of waste gas heating. The ceramic regenerator should be divided into more than three (including three) zones or chambers. Each regenerator undergoes the procedures of heat storage, heat release and cleaning in turn, and works continuously.
蓄热室“放热”后应立即引入部分已处理合格的洁净排气对该蓄热室进行清扫(以保证VOC去除率在99%以上),只有待清扫完成后才能进入“蓄热”程序。RTO蓄热式废气处理设备,它的特点是:运行费用省,有机废气的处理效率高的优点,适应废气浓度1000~10000mg/m3 ,分解效率:99%--99.5%。是目前更为经济可靠的达到50mg/m3严格的排放标准的VOCs治理技术,得到了广泛的应用。
After the "heat release" of the regenerator, part of the qualified clean exhaust gas should be introduced to clean the regenerator immediately (to ensure that the VOC removal rate is above 99%). Only after the cleaning is completed can the "heat storage" procedure be started. The characteristics of RTO regenerative waste gas treatment equipment are: low operation cost, high treatment efficiency of organic waste gas, suitable for waste gas concentration of 1000 ~ 10000mg / m3, decomposition efficiency: 99% - 99.5%. At present, it is the most economical and reliable VOCs treatment technology which reaches the strict emission standard of 50mg / m3, and has been widely used.
RTO有机废气处理设备又可分为阀门切换式和旋转式。阀门切换式RTO是更常见的一种RTO有机废气处理设备,包括典型的代技术2室式RTO和第二代技术3室式RTO。其由2个或多个陶瓷填充蓄热室, 通过阀门的切换, 改变气流的方向, 从而达到预热VOC废气的目的。
催化燃烧设备
RTO organic waste gas treatment equipment can be divided into valve switching type and rotary type. Valve switching RTO is the most common RTO organic waste gas treatment equipment, including the typical first generation technology 2-chamber RTO and the second-generation technology 3-chamber RTO. The regenerator is filled with two or more ceramics, and the direction of air flow is changed by switching valves, so as to preheat VOC waste gas.
一般来讲,蓄热室越多净化效率越高、热效率越高,常用的还有5室RTO和12室RTO,5室RTO造价成本高已经很少使用,12室RTO变形为圆柱形旋转式的,成为第三代技术的产品。2室式RTO没有清扫过程,在阀门切换时有废气和处理后的洁净气体短路现象,平均净化率只能达到90%,不能满足当前50mg/m3 的环保排放要求;
Generally speaking, the more regenerators, the higher the purification efficiency and the higher the thermal efficiency. Commonly used are 5-chamber RTO and 12 chamber RTO. The cost of 5-cell RTO is high and has been rarely used. The 12 chamber RTO is deformed into a cylindrical rotary type, becoming the product of the third generation technology. There is no cleaning process for 2-chamber RTO, and there is short-circuit phenomenon of waste gas and clean gas after treatment during valve switching. The average purification rate can only reach 90%, which can not meet the current environmental protection emission requirements of 50mg / m3;
RTO处理有机废气具有如下优点:
RTO has the following advantages in treating organic waste gas
(1)几乎可以处理所有种类有机物的废气;
(1) It can treat almost all kinds of organic waste gas;
(2)处理有机废气流量的弹性很大(名义流量20%~120%);
(2) The flow rate of organic waste gas is very elastic (nominal flow rate is 20% ~ 120%);
(3)可以适应有机废气中VOCs的组成和浓度变化、波动;
(3) It can adapt to the change and fluctuation of VOCs composition and concentration in organic waste gas;
(4)对废气中夹带少量灰尘、固体颗粒不敏感;
(4) It is not sensitive to a small amount of dust and solid particles in the exhaust gas;
(5)在所有热力燃烧净化法中的热效率;
(5) Among all the thermal combustion purification methods, the thermal efficiency is the highest;
(6)在合适的废气浓度条件下无需添加辅助燃料而实现自供热操作;
(6) Under the condition of appropriate exhaust gas concentration, self heating operation can be realized without adding auxiliary fuel;
(7)净化效率高达99.5%;
(7) The purification efficiency is as high as 99.5%;
(8)维护工作量少,操作安全可靠,有机沉淀物可周期性的清除,蓄热体可更换,整个装置的压力损失较少,压力波动小,装置使用寿命长。
(8) It has the advantages of less maintenance, safe and reliable operation, periodic removal of organic sediment, replacement of heat storage body, less pressure loss and pressure fluctuation of the whole device, and long service life of the device.
但RTO设备直接处理风量大、浓度低的有机废气能耗高;RTO设备要求尽可能连续操作;RTO一次性投资费用相对较高,不能适合处理含硫、含氯、含卤素的有机物。
However, RTO equipment directly processes organic waste gas with large air volume and low concentration, and its energy consumption is high; RTO equipment requires continuous operation as far as possible; the one-time investment cost of RTO is relatively high, so it is not suitable for the treatment of organic matters containing sulfur, chlorine and halogen.
