摘要
为了解决城市周边小企业挥发性有机物空气污染问题,研发了一种新型多蓄热室旋转换向蓄热式热氧化器,对现有蓄热式热氧化器内不合理的流通截面积分配比例进行了改进,并在北京市郊某工厂建设了处理能力3 000 m3/h的应用示范装置。应用情况表明,新型蓄热式热氧化器对VOC的处理效率可达96%,同时比常规热力焚烧炉节能70%以上。通过对蓄热式热氧化器出口残留VOC来源和各种能量消耗数据的分析和计算,揭示了影响蓄热式热氧化器示范装置VOC处理效果和燃料消耗量的因素,并提出了进一步改进示范装置的措施:控制旋转换向阀门的泄漏率至1%以下以提高处理效率;降低外壁温度、提高废气预热温度以减少能量消耗。
A new type of multiple-chamber rotary reversing regenerative thermal oxidizer（RTO） was developed for volatile organic compound（VOC） air pollution problem in suburban factories.Unreasonable flow area distribution of current regenerative chamber was improved.A demonstration RTO device with capacity of 3 000 m3/h was constructed in a suburban factory of Beijing.The destruction and removal efficiency of the new type RTO could reach 96% as while as the energy saving could achieve upwards 70% comparing with convectional thermal oxidizers.Factors which impact VOC abatement efficiency and fuel consumption were discussed through outlet VOC sources analysis and energy consumption calculation methods.In addition,further improving methods for the RTO demonstration project were presented：controlling the rotary valve leakage rate less than 1% to increase the abatement efficiency,decreasing the out wall temperature and raising waste air preheating temperature to reduce the energy consumption.
