ENERGY-SAVING ULTRALOW FLUE GAS PURIFICATION SYSTEM FOR WASTE INCINERATION

摘要

An energy-saving ultralow flue gas purification system for waste incineration, comprising a high-speed rotary atomizer (1), a semi-dry reaction tower (2), a baghouse filter (8), an SCR reaction tower (9), a water medium type flue gas cooler (11), an induced draft fan (13), and a chimney (14). An upper portion of the semi-dry reaction tower (2) is provided with the high-speed rotary atomizer (1); a sodium bicarbonate dry powder injection device (6) and an activated carbon injection device (7) are provided on a flue between the semi-dry reaction tower (2) and the baghouse filter (8); and flue gas enters the SCR reaction tower (9) from the baghouse filter (8), and after the catalytic denitrified flue gas passes through the water medium type flue gas cooler (11) and is cooled to 130°C, the flue gas is discharged into the chimney (14) by means of the induced draft fan (13).
