Detailed description of the invention
Below in conjunction with accompanying drawing, describe exemplary embodiment of the present utility model in more detail, above and other aspect of the present utility model and advantage will become and more be readily clear of.
embodiment one:
As shown in Figure 1 and Figure 2, the cross-flow moving bed device of many points of bins of the present utility model, comprises influent header 1, outlet header 2, moving bed 3, charging aperture 4, discharge port 5, porous plate 6, dividing plate 7.Moving bed is divided into four bins by dividing plate 7 and porous plate 6, is respectively the first bin 3-1, the second bin 3-2, the 3rd bin 3-3, the 4th bin 3-4.In smoke inlet direction, influent header 1 is welded on the left side of first, second bin of moving bed; In exhanst gas outlet direction, outlet header 2 is welded on the right side of moving bed (the 3rd, the 4th bin).Porous plate 6 is arranged perpendicular to flue gas flow direction, passing through for flue gas; First and the 3rd bin adjacent be porous plate, second and the 4th bin adjacent be porous plate.Dividing plate 7 is parallel to flue gas flow direction and arranges, for the separation of bin.First and second bin adjacent is dividing plate, and the 3rd and the 4th bin adjacent is dividing plate.Material enters batcher through hopper, and under hopper, corresponding each bin arranges feed valve, and material enters different bin through feed valve.The each bin of corresponding charging aperture is provided with a feed valve, and each bin of corresponding discharge port is provided with a discharge valve.
When amount of sulfur contenting in smoke is higher, flue gas is introduced into the first bin 3-1, the second bin 3-2, by controlling, feed valve makes material enter the first bin 3-1, the speed of the second bin 3-2 is accelerated, flue gas is made first to carry out desulfurization at the first bin 3-1, the second bin 3-2, after flue gas sulphur concentration tentatively reduces, then enter the first bin 3-3, the second bin 3-4 continuation desulfurization, slack-off at this workshop section's material flow, material fully contacts with flue gas, reaches the effect of high efficiency desulfurization.
