Advanced Scrubbing/Filtration Devices for Pollution Control in Medical Laboratory Waste Incineration System

This research investigated the release of pollutants from a medical laboratory waste incineration system and assessed the effectiveness of advanced scrubbing and filtration devices. Samples of flue gas, fly ash, bottom ash, scrubbing wastewater, and sludge were collected for analysis. By introducing liquid waste solvent into the primary combustion chamber, it is possible to achieve an average incineration temperature of over 950°C, ensuring a combustion efficiency of 99.93%. The study findings indicate that the use of advanced scrubbing/filtration devices effectively removed pollutants, resulting in pollutant concentrations in the stack flue gas that met emission standards. The system effectively protects the fabric filter against acid gas corrosion, as demonstrated by the removal of HCl at a rate exceeding 99.99%. Additionally, the two-stage scrubbing process involves converting condensable particulate matter (CPM) into filterable particulate matter (FPM) by reducing the temperature of the flue gas to 70°C. The fabric filter effectively removed FPM in a sequential manner. Therefore, the advanced scrubbing/filtration devices demonstrated exceptional efficacy in removing FPM and CPM, with removal efficiencies surpassing 99.8%.
