Description
Technical field
The utility model relates to a kind of absorption tower current equalizer.
Background technology
Wet FGD technique belongs to the desulfur technology of coal combustion, countercurrent spray tower is the wet desulphurization absorption tower relatively commonly used, and flue gas enters from bottom, absorption tower, and desulfurizing agent sprays into droplet by the nozzle on top, flue gas is reverse to be contacted with droplet, makes most of drop keep suspended state by flue gas in tower.On absorption tower, outlet arranges two-stage demister, and to remove the droplet carried in flue gas, after purification, flue gas is discharged by outlet flue at the bottom of tower.Be divided into uptake zone, zoneofoxidation and neutral zone from top to bottom in this absorption tower, described uptake zone is positioned at below shower 300mm with inner region, and zoneofoxidation is positioned at retort liquid level to uptake zone with lower area.The process that SO2 in flue gas dissolves in absorbing liquid almost all occurs in uptake zone, part HSO3 is only had to be oxidized to H2SO4 by the O2 in flue gas in this region, because tower body central negative pressure is large, cause that current equalizer center flue gas flow rate is fast, surrounding flow velocity is slow, slurries fallen by top and the smoke contacts time is short, contact area is little, react insufficient, make sulfur content in the flue gas of discharging not reach requirement, national standard is not reached to dust treatment effect, harmful effect is caused to environment.
Summary of the invention
The technical problems to be solved in the utility model is to provide that a kind of current-sharing is effective, flue gas evenly enters, alkaline slurry and the smoke contacts time is long, contact area is large, sufficient reacting, desulfurized effect is good, can reduce sulfur content and the absorption tower current equalizer containing fume amount in the flue gas of discharge.
Technical solution of the present utility model is: a kind of absorption tower current equalizer, comprise current equalizer plate body, its special character is: on current equalizer plate body, be provided with the many groups of current-sharings distributed ringwise from the inside to the outside dominate hole, the cross-sectional area that hole is dominated in described current-sharing reduces gradually according to order from outside to inside, described current equalizer plate body is dominated between hole in adjacent current-sharing and is provided with the secondary guide hole of current-sharing.
Described current-sharing is dominated hole and the secondary guide hole Jun Shiyou center current-sharing guide hole of current-sharing and inside and outside annular current-sharing guide hole and is formed, and to increase flue gas and alkaline slurry contact area and to extend contact time, reacts more abundant.
Arrival end and the port of export of described center current-sharing guide hole and inside and outside annular current-sharing guide hole are the conical surface.
Described center current-sharing guide hole and inside and outside annular current-sharing guide hole pass through link of boards from the inside to the outside.
The beneficial effects of the utility model are:
1, the cross-sectional area dominating hole by outer current-sharing of arranging to center reduces gradually, and dominate in adjacent current-sharing and between hole, to be provided with the secondary guide hole of current-sharing, the negative pressure that can solve tower body axle center place crosses the problem that ambassador's flue gas is flowed out fast by the center of tower body, thus make flue gas uniformly across flue gas flow equalizing device, reach flue gas flow equalizing object by computer aided calculation through actual measurement by the distance of exiting flue gas.
2, flow on the inwall of the major and minor guide hole of current-sharing of flue gas flow equalizing device by the alkali lye fallen above current equalizer major part under the pressure effect of flue gas, extend the time of staying of alkali lye, and add the contact area of alkali lye and flue gas flow equalizing device, flue gas and alkaline slurry time of contact is long, contact area is large, sufficient reacting, desulfurized effect is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that in Fig. 1, hole and the secondary guide hole of current-sharing are dominated in current-sharing;
Fig. 3 is the A-A sectional view in Fig. 2.
In figure: 1-current equalizer plate body, hole is dominated in 2-current-sharing, the secondary guide hole of 3-current-sharing, 4-center current-sharing guide hole, annular current-sharing guide hole in 5-, 6-outer ring current-sharing guide hole, 7-gusset.
Detailed description of the invention
As shown in the figure, a kind of absorption tower current equalizer, comprise current equalizer plate body 1, current equalizer plate body 1 is provided with the many groups of current-sharings distributed ringwise from the inside to the outside and dominates hole 2, the cross-sectional area that hole 2 is dominated in described current-sharing reduces gradually according to order from outside to inside, described current equalizer plate body 1 is dominated between hole 2 in adjacent current-sharing and is provided with the secondary guide hole 3 of current-sharing, hole 2 and current-sharing secondary guide hole 3 Jun Shiyou center current-sharing guide hole 4 and interior is dominated in described current-sharing, outer ring current-sharing guide hole 5, 6 are formed, described center current-sharing guide hole 4 and interior, outer ring current-sharing guide hole 5, arrival end and the port of export of 6 are the conical surface, described center current-sharing guide hole 4 and interior, outer ring current-sharing guide hole 5, 6 are connected by gusset 7 from the inside to the outside.
During operation, flue gas is by current equalizer grillage 1 dominates by the outer current-sharing reduced gradually to center cross-sectional area the secondary guide hole 3 of current-sharing that the gap location between hole 2 is dominated in hole 2 and each current-sharing, the negative pressure that can solve tower body axle center place crosses the problem that ambassador's flue gas is flowed out by center, thus make flue gas uniformly across flue gas flow equalizing device, carry out computer aided calculation by the distance of exiting flue gas and reach flue gas flow equalizing object through actual measurement.Center current-sharing guide hole 4 and inner and outer rings current-sharing guide hole 5,6 structure, increase flue gas and alkaline slurry contact area and extend contact time, reacting more abundant.
These are only specific embodiment of the utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
