摘要: 静电除尘技术由于其风阻小、PM2.5净化效率高等特点，在空气污染治理中的应用备受关注。针对民用静电式空气净化装置的高压静电模块产生臭氧的问题，对比了在不同尺寸密封舱中高压静电模块与催化模块耦合前后臭氧浓度水平。依据单空间充分混合假设下的臭氧质量守恒方程和室内臭氧浓度衰减特性，针对有静电式空气净化装置的室内环境建立了可工程实用的臭氧浓度预测模型，并结合密封舱实验对预测模型进行了验证。研究表明高压静电耦合催化模块后能使舱内臭氧浓度维持在安全限值以内。该预测模型能有效预测室内臭氧浓度，对静电式空气净化器设计有指导意义。

Abstract: Electrostatic precipitators have attracted tremendous attention for air purification due to their high PM 2.5 removal efficiency and low pressure drop. However, drawbacks such as the generation of hazardous ozone in high voltage modules in air purification facilities cannot be ignored. Therefore, in this study, methods for ozone concentration control and prediction were studied. In the experiment, the ozone concentration was analyzed before and after coupling of a high-voltage electrostatic module and catalyst module in airtight cabins with different dimensions. A practical prediction model of ozone concentration for indoor environments with electrostatic air cleaners was established and further experiments were carried out for validation. The mass balance equations and attenuation characteristics of ozone applied in the model establishment were based on an assumption of a well-mixed air volume. Results showed that the coupled high-voltage electrostatic module and catalyst module could effectively control the ozone concentration, keeping it below the safety limits for eight hours. It was concluded that indoor ozone concentration could be effectively predicted using the prediction model. This should provide potential guidance for air cleaner design.
