Detailed description of the invention
Below in conjunction with accompanying drawing, describe exemplary embodiment of the present invention in more detail, above and other aspect of the present invention and advantage will become and more be readily clear of.
embodiment one:
As shown in Figure 1, Figure 2, Figure 3 shows, the cross-flow moving bed device of many points of bins of band waterbaffle of the present invention, comprises influent header 1, outlet header 2, moving bed 3, charging aperture 4, discharge port 5, porous plate 6, waterbaffle 7.Moving bed is divided into four bins by waterbaffle 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.Waterbaffle 7 is parallel to flue gas flow direction and arranges, for the separation of bin.First and second bin adjacent is waterbaffle, and the 3rd and the 4th bin adjacent is waterbaffle, and waterbaffle is used for material cooling.Waterbaffle is provided with cooling tube row, and is provided with the import and outlet that are connected with cooling system, and in this example, waterbaffle can adopt membrane wall form.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.
