Embodiment 1
[0062] A hazardous waste incineration production line, the flue gas volume under working conditions is 66832-68661Nm 3 / h, the flue gas outlet temperature of the quench tower is 490-510°C, the inlet flue gas temperature of the deacidification tower is 150-180°C, and the sulfur dioxide concentration is 4500-6600 mg / Nm 3 , hydrogen chloride concentration 2000-3500mg / Nm 3 , the concentration of hydrogen fluoride is less than 100mg / Nm 3 , use the method in the present invention to carry out flue gas deacidification, with figure 1 For the deacidification device, a two-stage deacidification tower is used for absorption.
[0063] like figure 2 As shown, pulping was carried out according to the ratio of magnesium oxide to water as 1:5, and the dosage of magnesium oxide was 200kg / h. The obtained slurry is sent to the primary and secondary deacidification towers by the slurry pump, and the liquid-gas ratio is controlled at about 9. After aeration and solid-liquid separation, the l...
Embodiment 2
[0066] A medical waste incineration production line, the working condition flue gas volume is 8000-12000Nm 3 / h, the flue gas outlet temperature of the quench tower is 500-520°C, the inlet flue gas temperature of the acid absorption tower is 150-180°C, and the hydrogen chloride concentration is 3900-4700 mg / Nm 3 , the sulfur dioxide concentration is less than 50mg / Nm 3 , the concentration of hydrogen fluoride is less than 100mg / Nm 3 , use the method in the present invention to carry out flue gas deacidification, with figure 1 For the deacidification device, a single-stage deacidification tower is used for absorption.
[0067] like figure 2 As shown, pulping was carried out according to the ratio of magnesia to water as 1:6, and the dosage of magnesia was 50kg / h. The obtained slurry is sent to the single-stage deacidification tower respectively by the slurry centrifugal pump, and the liquid-gas ratio is controlled at about 10. After the liquid after absorbing acid gas is ...
