催化燃烧工艺

 

 ① 在工业生产过程中,排放的有机尾气通过引风机进入设备的旋转阀,通过选转阀将进口气体和出口气体完全分开。
 ② 气体首先通过陶瓷材料填充层(底层)预热后发生热量的储备和热交换,其温度几乎达到催化层(中层)进行催化氧化所设定的温度,这时其中部分污染物氧化分解;废气继续通过加热区(上层,可采用电加热方式或天然气加热方式)升温,并维持在设定温度;其再进入催化层完成催化氧化反应,即反应生成CO2和H2O,并释放大量的热量,以达到预期的处理效果。
 ③ 经催化氧化后的气体进入其它的陶瓷填充层,回收热能后通过旋转阀排放到大气中,净化后排气温度仅略高于废气处理前的温度。
 ④ 系统连续运转、自动切换。通过旋转阀工作,所有的陶瓷填充层均完成加热、冷却、净化的循环步骤,热量得以回收。
      RCO蓄热式催化燃烧装置使用旋转阀替代了传统设备中众多的阀门以及复杂的液压设备。有机物去除率可以达到98%以上,热回收率达到95-97%。
 
  适用范围
  RCO处理技术特别适用于热回收率需求高的场合,也适用于同一生产线上,因产品不同,废气成分经常发生变化或废气浓度波动较大的场合。应用行业包括汽车、造船、摩托车、自行车、家用电器、集装箱等生产厂的涂装生产线。石油、化工、橡胶、油漆,涂料、制鞋粘胶、塑胶制品、印铁制罐、印刷油墨、电缆及漆包线等生产线的废气处理,尤其适用于需要热能回收的企业或烘干线废气处理,可将能源回收用于烘干线,从而达到节约能源的目的。可处理的有机物质种类包括苯类、酮类、酯类、酚类、醛类、醇类、醚类和烃类等等。

① in the process of industrial production, the organic exhaust gas discharged through the induced draft fan enters the rotary valve of the equipment, and the inlet gas and the outlet gas are completely separated by the rotary valve. 

( 2 ) the gas is firstly heated by the heat storage and heat exchange through the ceramic material filling layer ( bottom layer ), and the temperature is almost reached the temperature set by catalytic oxidation of the catalytic layer ( middle layer ), where some of the pollutants are decomposed by oxidation; The exhaust gas continues to heat up through the heating area ( upper layer may be heated by electric heating or natural gas heating ) and maintained at the setting temperature; It enters the catalytic layer to complete the catalytic oxidation reaction, that is, the reaction generates CO2 and H2O, and releases a lot of heat to achieve the desired treatment effect. 
③ after catalytic oxidation, the gas enters the other ceramic filling layer. after the heat energy is recovered, the heat energy is discharged into the atmosphere through the rotary valve, and the exhaust gas temperature is only slightly higher than the temperature before the waste gas treatment. 
④ continuous operation and automatic switching of the system. Through the rotary valve work, all the ceramic filling layers complete the cycle steps of heating, cooling, purification, and the heat can be recovered. 
Rco regenerative catalytic combustion device uses rotary valve instead of many valves and complex hydraulic equipment in traditional equipment. The removal rate of organic matter can reach more than 98 % and the thermal recovery rate is 95 - 97 %. 


Scope of application

Rco treatment technology is especially suitable for high heat recovery rate, and it is also suitable for the same production line, because of the different products, the waste gas composition often changes or the concentration fluctuation of the exhaust gas. The application industry includes automobile, shipbuilding, motorcycles, bicycles, household appliances, containers and other production lines of production lines. Waste gas treatment of oil, chemical, rubber, paint, paint, shoe - making viscose, plastic products, printing ink, cable and enameled wire, etc., especially suitable for treatment of enterprises that need heat energy recovery or waste gas treatment of drying line, can use energy recycling for drying line, so as to achieve the purpose of saving energy. The types of organic substances that can be treated include benzene, ketones, esters, phenols, aldehydes, alcohols, ethers and hydrocarbons, and so on
