Abstract
The invention relates to waterbaffle-carrying multi-chamber cross-flow moving bed equipment. The equipment comprises an inlet header (1), an outlet header (2), four chambers (3), feed inlets (4), discharge ports (5), porous plates (6) and waterbaffles (7). A material enters a feeder through a hopper, a feed valve is arranged below the hopper corresponding to each chamber, and the material enters different chambers through the feed valves. Inside the moving bed body, multiple chambers are separated through the porous plates and the waterbaffles; the porous plates are arranged to be vertical to the flow direction of flue gas and are used for allowing flue gas to pass through; and the waterbaffles are arranged to be parallel to the flow direction of flue gas and are used for cooling the material in the moving bed. Under the condition of high sulphur content of flue gas, sectional purification of flue gas can be realized. When flue gas enters different chambers, the feed valves are controlled to control descent velocity of the material. Through different velocity combinations, overall descent velocity of the material is reduced, so as to decrease consumption of the material. The equipment of the invention has strong expandability. Four to eight chambers can be arranged according to needs.

Background technology
Utilize and material loaded the technology such as sulfur dioxide, nitrogen oxide that cross-flow moving bed device removes in coal steam-electric plant smoke and applied to some extent, but cross-flow moving bed device itself and design thereof also exist a lot of not enough, as: (1), when smoke inlet is higher containing sulphur concentration, in bed, material flow is too fast increases material wearing and tearing; (2) the cross-flow moving bed closed environment that normally a space size is limited, due to exotherm, in bed, temperature is too high, the easy ignition of material.
Summary of the invention
For overcoming the above problems, the present invention is divided into multiple bin at design aspect cross-flow moving bed, and each bin is all designed to square passageway, facilitates material cloth.Meanwhile, when inlet flue gas sulfur-bearing excessive concentration, can control to allow (bin 3-1, bin 3-2) material decrease speed in the bin in smoke inlet direction accelerate, effectively can reduce material wearing and tearing; Material decrease speed can be allowed to slow down when flue gas enters bin (bin 3-3, bin 3-4) near Way out, flue gas fully be contacted with material, completes flue gas desulfurization course.Under the increase of maintenance adsorption tower overall material decrease speed faster situation, realize removing of high-concentration sulfur dioxide.
The present invention relates to the cross-flow moving bed device of a kind of band waterbaffle many points of bins,
This device comprises influent header (1), outlet header (2), four bin (3), porous plate (6), waterbaffles (7) being arranged in two row two and arranging;
In smoke inlet direction, described influent header (1) is welded on the outside of two bins (3-1,3-2) side by side; In exhanst gas outlet direction, outlet header (2) is welded on the outside of another two bins (3-3,3-4) side by side;
Each described bin (3) has charging aperture (4) and discharge port (5);
Described four bins (3) are separated out by porous plate (6) and waterbaffle (7) in the body of described device; Described porous plate (6) is arranged perpendicular to flue gas flow direction, and waterbaffle (7) is parallel to flue gas flow direction and arranges.
The invention still further relates to a kind of method using the cross-flow moving bed device of above-mentioned many points of bins to control Flow of Goods and Materials speed, material enters different bins respectively through feed valve, according to flue gas sulphur concentration characteristic distributions, each bin material decrease speed can be controlled respectively, effectively improve the desulfurization performance of material further.The invention solves single bin material uneven distribution and material to wear and tear large drawback.
Bin involved in the present invention is square passageway.
The quantity of bin involved in the present invention can adjust.
The waterbaffle being parallel to flow of flue gas direction is set in bin involved in the present invention, for the cooling of material in moving bed.
When smoke inlet changes containing sulphur concentration, feed valve can be controlled the inventory entering bin is changed thereupon, reach higher desulfuration efficiency.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 1, the cross-flow moving bed device of one band waterbaffle many points of bins provided by the present invention, this device comprises influent header (1), outlet header (2), bin (3), charging aperture (4), discharge port (5), porous plate (6), waterbaffle (7).Material enters batcher (not shown) through hopper (not shown), and under hopper, corresponding each bin arranges feed valve, and material enters different bin through feed valve by charging aperture (4).Discharge valve is installed in discharge port (5) below.Multiple bin is separated out by porous plate and waterbaffle in moving bed body, porous plate arranges perpendicular to flue gas flow direction, passes through for flue gas, waterbaffle has water cooled pipeline, and described waterbaffle is parallel to flue gas flow direction and arranges, and can be used for material cooling in moving bed.Flue gas enters cross-flow moving bed by influent header import department, and this moving bed is divided into multiple bin, is finally exported by outlet header exit.
When amount of sulfur contenting in smoke is higher, flue gas is introduced into described two bins (3-1,3-2) side by side, by control described feed valve make material enter described two side by side bin (3-1,3-2) speed accelerate, make flue gas described two side by side bin (3-1,3-2) first carry out desulfurization, after flue gas sulphur concentration tentatively reduces, enter again described another two side by side bin (3-3,3-4) continue desulfurization, at described another two, bin material flow is slack-off side by side, material fully contacts with flue gas, reaches the effect of high efficiency desulfurization.
Apparatus of the present invention can realize point bin purification of flue gas under the condition that amount of sulfur contenting in smoke is higher.When flue gas enters different bin, control feed valve and control material decrease speed, reduce throughout its mass decrease speed by friction speed combination, thus reduce supplies consumption.Extensibility of the present invention is strong, can arrange four to eight points of storehouses as required.
Obviously, those skilled in the art can carry out various change and modification to the present invention and not depart from the spirit and scope of the present invention.Like this, if belong within the scope of the claims in the present invention and equivalent technology thereof to these amendments of the present invention and modification, then the present invention is also intended to comprise these change and modification.
