Abstract
The utility model relates to a dry flue gas desulfurization device for circulating fluidized beds, which comprises a lime slaker, a slaked lime bin, a desulfurization tower, a dust collector, a chimney, a fan and a lime-ash bin; and the dry flue gas desulfurization device is characterized in that the lime slaker is connected with the slaked lime bin, the slaked lime bin is connected with the desulfurization tower, one side of the downside of the desulfurizing tower is provided with a flue gas inlet, the other side of the desulfurization tower is connected with the dust collector, the fan is arranged between the dust collector and the chimney, one end of the dust collector is connected with the desulfurizing tower, the other end of the dust collector is connected with the fan, the fan is connected with the chimney, the lower end of the dust collector is connected with the lime-ash bin, and the dust collector is also connected with the desulfurization tower so as to carry out recovered ash recirculation. The dry flue gas desulfurization device disclosed by the utility model has the beneficial effects that flue gas treated by the dry flue gas desulfurization device is high in desulfurization efficiency, good in reliability and low in operation and maintenance costs; and the feed solid circulation and by-products are all dry, therefore, no wastewater is drained.
Description
Technical field
The utility model relates to a kind of circulation fluidized bed dry method flue gas desulfur device, is applied to the urban life boiler, the flue dust desulfurization of papermaking, chemical industry boiler, industrial blast furnace, foundry cupola etc.
Background technology
Sulfur removal technology of the prior art is from the boiler SO that contains dust out
2Flue gas directly enter in the tower from the bottom of desulfurizing tower, inhomogeneous with mixing of quick lime, desulfurized effect is poor.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of circulation fluidized bed dry method flue gas desulfur device is provided, the technical scheme that its technical problem that solves the utility model adopts is: structure of the present utility model comprises limeslaker, the niter ash silo, desulfurizing tower, deduster, chimney, blower fan, cinder tank, it is characterized in that limeslaker is connected with the niter ash silo, the niter ash silo is connected with desulfurizing tower, a following side of desulfurizing tower is provided with gas approach, the opposite side of desulfurizing tower is connected with deduster, be provided with blower fan between deduster and the chimney, deduster one end is connected with desulfurizing tower, the other end of deduster is connected with blower fan, blower fan is connected with chimney, the lower end of deduster is connected with cinder tank, and deduster also is connected with desulfurizing tower receives ash recirculation.
Operation principle: from the boiler SO that contains dust out
2Flue gas rise through Venturi tube from the bottom of desulfurizing tower and enter in the tower.Quick lime stores in the niter ash silo add water digestion in digester after.A certain amount of niter buck is added in Venturi throat mouth upper end, in desulfurizing tower with the flue gas mixed flow and with flue gas in SO
2Generate calcium sulfite and calcium sulfate, SO
2Deviate from effective sufficient reacting.
The beneficial effects of the utility model are, the utility model is high through the smoke desulfurization efficiency that deals, good reliability, and the operation maintenance expense is low, and reinforced solid circulation and byproduct all be dry state, non-wastewater discharge.
