摘要
VOCs治理是现阶段我国大气污染控制领域重点关注的问题,催化燃烧技术已广泛应用于工业VOCs的治理;利用数值模拟方法探讨催化燃烧室内流体流动特征,探讨催化氧化温度及催化剂孔径、空隙率等因素对燃烧效率的影响;模拟计算结果表明,当温度高于一定值时,浓度变化对催化燃烧反应速度的影响高于温度变化的影响;为保证设备对甲苯浓度的适应性,要求催化剂孔径小于1.5 mm,空隙率大于0.85.
Abstract
VOCs treatment is a key concern in the field of air pollution control in our country at this stage.Among them,catalytic combustion technology has been widely used in industrial VOCs treatment.The numerical simulation method was used to explore the influence of flow characteristics,pore size,temperature,porosity,and other factors on combustion efficiency in catalytic combustion chambers.The simulation results showed that when the temperature was above a certain value,the effect of concentration change on catalytic combustion reaction rate was higher than that of temperature change.To ensure the adaptability of the equipment to toluene concentration,a pore size smaller than 1.5mm and a void fraction greater than 0.85 were required.
