低浓度可燃废气处理系统流动特性研究
, PP. 32-39
Keywords: 低浓度可燃废气,催化燃烧,流动特性,阻力损失
Abstract:
在自建的低浓度可燃废气处理系统上进行了装填方式、循环周期、气体流速和浓度对系统冷、热态气体流动特性影响的研究。结果表明，系统冷、热态气体流动时的阻力损失均表现出明显的周期性；混合装填蓄热体与催化剂更有利于系统的稳定燃烧；随着气体流速的增加，气体流动阻力和流速的关系逐渐从线性关系过渡为近抛物线关系；热态时系统的气体流动阻力大于冷态，并且受循环周期、浓度对系统温度的影响，在1/2周期内呈单调上升趋势。根据试验结果对仅装填蓄热体时系统的冷态流动阻力损失按照ergun方程的形式进行回归，其结果与试验结果吻合，为后续的数值模拟奠定了基础。
