Removal characteristics of PCDD/Fs by an adsorbent injection coupled with a baghouse filter system
In this study, we explore the influence of the baghouse differential pressure, the baghouse running time, and activated carbon addition on dioxin emissions at the baghouse outlet during waste incineration. The experimental results showed that there was a critical value of the baghouse differential pressure. When the baghouse differential pressure was less than the critical value, the dioxin toxic equivalent at the baghouse outlet decreased with an increase in the differential pressure; and when the baghouse differential pressure was greater than the critical value, the dioxin toxic equivalent increased with an increase in the differential pressure. There was also a critical value for the influence of the baghouse running time on the dioxin emissions at the baghouse outlet. Within the range of experimental data, as the baghouse running time increased, the dioxin toxic equivalent at the baghouse outlet first decreased and then maintained a stable fluctuation. The addition of activated carbon effectively reduced the dioxin toxic equivalent at the baghouse outlet, which decreased with an increase in the amount of added activated carbon. This study provides a preliminary reference and data support to control dioxins during waste incineration.
期刊介绍:
Atmospheric Pollution Research (APR) is an international journal designed for the publication of articles on air pollution. Papers should present novel experimental results, theory and modeling of air pollution on local, regional, or global scales. Areas covered are research on inorganic, organic, and persistent organic air pollutants, air quality monitoring, air quality management, atmospheric dispersion and transport, air-surface (soil, water, and vegetation) exchange of pollutants, dry and wet deposition, indoor air quality, exposure assessment, health effects, satellite measurements, natural emissions, atmospheric chemistry, greenhouse gases, and effects on climate change.
