The device for improving the oxidation characteristic can improve the reliability of system operation, improve the oxidation speed of a serous fluid, enhance the oxidation effect of the serous fluid, lower the oxidation fan flow and pressure energy and increase the pH value of the upper-grade serous fluid, and has a great promoting action on the stable and high-efficiency operation of a desulphurization system.
Description
Technical field
The present invention relates to a kind of wet method fume desulfurizing system (WFGD) or a kind of agitating device that can improve oxidation characteristic of similar field of being used for.
Background technology
The device of accelerating oxidation is a single-stage side-feeding type blade agitators in known this field at present, generally be installed in the desulfurizing tower sidepiece, rotate with certain speed by driven by motor metal shaft and metal blade, stir slurries by blade again, oxidation air blasts in blade the place ahead, and the blade that is rotated stirs diffusing, makes it mix more evenly with slurries, enlarge response area, increase reaction speed.
The another one effect of single-stage side-feeding type agitating device is to stir slurries, prevents that the solid particle deposition hardens in the slurries.
For single-stage side-feeding type agitating device, oxidation air pipe position is darker, and the pressure head of oxidation air blower fan is bigger, and the consumption of the energy of oxidation air blower fan is bigger.In addition because desulfurizing tower is generally all huger, if having a mixer to hinder for some reason in the single-stage side-feeding type agitating device or other reasons when deactivating, the effect of oxidation and stirring all can be subjected to tangible influence.
Summary of the invention
Technical problem: technical problem to be solved by this invention is at above-mentioned the deficiencies in the prior art, and a kind of agitating device that improves oxidation characteristic is provided.
Technical scheme: the utility model solves the technical scheme that its technical problem adopts and is:
A kind of agitating device that improves oxidation characteristic, comprise the slurries pond, agitator and oxidation air pipe is characterized in that: described agitator has the 2-5 level, and be successively set on the short transverse in slurries pond, described oxidation air pipe is near agitator setting topmost.
Described each grade agitator comprises 2-6 side-feeding mixer.
Have difference in height between at different levels, difference in height is 0.5-1m.
Beneficial effect: agitating device of the present invention comprises multistage agitator, and a main effect of higher level's agitator is that the oxidation air that will blast disperses downwards, and oxidation air is stirred diffusing on the way once more by subordinate's agitator, and then escapes via buoyancy and mobile effect ascension.In this process, oxidation air and slurries mix more even, and the utilization rate of oxidation air increases greatly, therefore can reduce the oxidation air consumption.In addition and because improve oxidation air pipe position, the pressure head of oxidation fan reduces, and has reduced the energy resource consumption of oxidation fan.
Desulphurization system in running, HSO in the slurries of top, slurries pond
3 -Ion concentration is more, and pH value is lower, and higher level's stirring system can push these slurries the below in the multistage agitating device, improves pH value, more helps desulfurization and absorbs.
In the multistage agitator, deactivate if there is a side-feeding type agitating device to break down, can not produce very big influence to the oxidation and the mixing effect of integral body, system can continue stable operation.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is the vertical view 1 that the present invention improves the oxidation characteristic agitating device.
Fig. 2 is the Front view 2 that improves the oxidation characteristic device.
Higher level's agitator 1 is arranged, subordinate's agitator 2, oxidation air pipe 3 among the figure.
The specific embodiment
Improve the oxidation characteristic agitating device and comprise higher level's agitator 1 and subordinate's agitator 2,, in the middle of this two-stage agitator, can also increase the agitator of some according to the height difference in slurries pond.
Top newly absorbs SO
2Slurries and oxidation air under the promotion of higher level's stirring system, move downward, stirred diffusingly immediately again by subordinate's stirring system, make oxidation reaction more fully rapidly.Reduced oxidation fan flow and pressure head simultaneously, improved the pH value of higher level's slurries, and increased desulphurization system reliability of operation and stability.
Agitating device of the present invention is made up of N (2≤N≤5) level agitator, determines according to slurries pond height.
Difference in height between the agitators at different levels is H (0.5≤H≤1), determines according to slurry viscosity.
Every grade of agitator is made up of the individual agitator of n (2≤N≤6), determines according to slurries pond diameter.
Agitator axis that each is independent and slurries pond be angle α (10 °≤α≤10 °) radially, so that slurries produce eddy flow in the horizontal direction, promotes slurries to stir.Wherein negative angle be axis at slurries pond left radially, positive-angle be axis in the slurries pond radially right-hand.
In the present embodiment, agitating device comprises the two-stage agitator, be positioned at higher level's agitator 1 and the subordinate's agitator 2 that is positioned at lower end, slurries pond of upper end, slurries pond, the axial angle β of higher level's agitator 1 agitator axis and slurries pond (30≤β＜90), so that higher level's slurries and oxidation air move downward, subordinate's agitator 2 agitator axis and the axial angle theta in slurries pond (30 °≤θ≤120 °).
