  1. High Temperature and Pressure<\/strong>
    Flue gas typically exits at 800\u00b0C to 1100\u00b0C<\/strong>. This high temperature and pressure pose challenges for dust removal equipment.<\/li>
  2. Complex Gas Composition<\/strong>
    Incinerating waste releases various gases, including sulfur oxides, nitrogen oxides, hydrochloric acid (HCl), hydrofluoric acid (HF), and toxic organic pollutants like dioxins and furans. It also releases heavy metals such as mercury, cadmium, and lead.<\/li>
  3. High Calorific Value<\/strong>
    The flue gas contains significant thermal energy. This energy can be recovered, improving overall efficiency.<\/li>
  4. Strong Acidity<\/strong>
    The process generates many acidic gases, such as sulfur dioxide and hydrochloric acid. These gases can react with water, leading to environmental pollution.<\/li>
  5. High Flow Rate<\/strong>
    Strong airflow in the incinerator results in a high flue gas flow rate, increasing pressure and wear on equipment.<\/li>
  6. Fine Particulate Size and High Viscosity<\/strong>
    The fine particulate size and high viscosity of the dust complicate the dust removal process.<\/li>
  7. High Moisture Content and Dew Point Temperature<\/strong>
    The moisture content in waste is high. During combustion, steam is produced, resulting in a moisture content of 23% to 30%<\/strong> and a dew point temperature of about 140\u00b0C<\/strong>. This requirement raises standards for dust removal equipment.<\/li><\/ol>\t\t\n\t<\/div>\n<\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    1. Pre-treatment<\/strong>
      This stage includes cooling, desulfurization, and denitrification, which prepare for effective dust removal.<\/p><\/li>

    2. Dry Dust Removal<\/strong>
      Equipment like electrostatic precipitators and bag filters remove solid particulate matter from the flue gas.<\/p><\/li>

    3. Semi-dry Dust Removal<\/strong>
      Techniques such as cyclonic and wet electrostatic separation are used to eliminate gaseous particulate matter, further purifying the gas.<\/p><\/li>

    4. Acid Removal<\/strong>
      Alkaline sprays help remove acidic gases, reducing their environmental impact.<\/p><\/li>

    5. Flue Gas Humidity Control<\/strong>
      Adjusting humidity improves the efficiency of subsequent adsorption and denitrification processes.<\/p><\/li>

    6. Post-treatment<\/strong>
      Finally, washing, adsorption, and catalytic processes remove any remaining pollutants, achieving higher purification levels.<\/p><\/li><\/ol>\t\t\n\t<\/div>\n<\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
