The invention discloses a method and equipment for eliminating white
smoke of desulfurized
flue gas, and the method comprises desulfurization treatment, specifically, atomization desulfurization and dust removal treatment are conducted by adopting a desulfurization
tower; and a
solid spray washing chamber, a condensation atomization washing chamber, a circulating
fluidization filtering chamber, a
mass transfer washing chamber and a
dehydration demisting chamber are arranged in the desulfurization
tower. The desulfurization
tower performs atomization desulfurization dust removal treatment and white
smoke elimination treatment, so that the desulfurization, white
smoke elimination and purification work on
flue gas is completed. Meanwhile, a boiler
flue gas
waste heat recovery technology, a
flue gas heat exchange and cooling technology and a
big data intelligent control technology are combined and adopted,
large white smoke of desulfurized
flue gas is deeply treated, white smoke
elimination of the desulfurized
flue gas is achieved, meanwhile, flue gas
waste heat is recovered and used for heating demineralized water and supplying the demineralized water to a boiler
deaerator, energy saving and consumption reduction are achieved, and large benefits are obtained; and a large amount of smoke exhaust
waste heat is recycled and used for boiler smoke waste heat recycling circulating water on the front portion, closed circulation of waste heat recycling is achieved, and heated demineralized water is used for a boiler
deaerator to be utilized.
