Abstract | The invention discloses a treatment system for high-concentration pollution tail gas generated after sludge incineration, and relates to the technical field of sludge incineration tail gas treatment. A dust removal unit in the treatment system comprises an electrostatic dust remover and a bag-type dust remover which are connected in sequence. The desulfurization unit comprises a first-stage absorption tower, a second-stage absorption tower and a heater which are connected in sequence, and a smoke outlet in the top of the first-stage absorption tower is connected to a smoke inlet of the second-stage absorption tower through a flue. The denitration unit comprises a flue gas-flue gas heat exchanger, an SCR heater and an SCR reactor which are connected in sequence, and flue gas at an outlet of the SCR reactor is subjected to heat exchange through the flue gas-flue gas heat exchanger and then is pumped to a chimney through an induced draft fan to be discharged. After the raw flue gas in the system passes through t |
