The incinerator scrubber, also known as a flue gas scrubber or air pollution control device, is designed to remove pollutants from exhaust gases generated during waste incineration. Incinerators burn municipal solid waste, hazardous waste, medical waste, and industrial waste to reduce volume and generate energy. This process releases harmful emissions, including sulfur dioxide (SO2), nitrogen oxides (NOx), hydrochloric acid (HCl), heavy metals, and particulate matter. An incinerator scrubber captures and neutralizes these pollutants by passing hot flue gases through a scrubbing system, where water or chemical solutions absorb and treat contaminants, ensuring cleaner emissions and environmental compliance.
