Flue gas ash removal and devulcanizer use are:
When boiler used, the flue gas that boiler is discharged entered the gas approach of flue gas ash removal and devulcanizer, simultaneously the alkali lye atomizer begin in flue dust atomization alkali lye, with the SO in the flue gas
2Reaction is by the suction of air-introduced machine, flue dust, alkali and SO
2The product of reaction and alkali lye enter the helical duct in the spiral separator together, and along the helical duct precession, and separated, last dust, alkali lye, alkali and SO
2Product enters in the water in the disposal box, and the air that has purified enters the space on mounting plate top in the housing through the blast pipe at spiral separator center, and outlet discharges through pure air.Dust is deposited at the bottom of the disposal box, and when being stacked into the dust discharge height of setting, pressure sensor starts the chain scraper machine, and dust is discharged outside the disposal box.When dust dropped to certain altitude, pressure sensor can cut out the chain scraper machine automatically.Use the utility model dedusting,, the phenomenon of reentrainment of dust can not occur, particularly can remove the SO in the flue gas owing to be wet dedusting
2Reduced pollution to environment.Promote the use of the utility model and help the comprehensive regulation of environment.
