Embodiment 2
As shown in figure 3, present embodiments provide a kind of wet method fume desulfurizing system, including absorption tower 600 and it is set to
Ceramet composite stirrer in the embodiment 1 of the lower part on absorption tower 600.Absorption tower 600 is for realizing flue gas on absorption tower
Desulfurizing and purifying in 600, purified flue gas enter chimney by absorption tower 600 and are discharged.Blender is located at the lower part of slurry pool, energy
Enough prevent solid particle from being precipitated in slurry pool, it is ensured that slurries can be uniformly delivered to dewatering system, avoid in absorption tower 600
Slurries deposition causes equipment damage, and the diffusion of oxidation air is reinforced, and oxidation and the gypsum for promoting calcium sulfite are brilliant
The growth of body and the dissolving of lime stone.
Arrangement of the blender in 600 bottom of absorption tower can be there are many mode, and blender should arrange conjunction in 600 bottom of absorption tower
Reason avoids in absorption tower 600 slurries heavy to give full play to the function of blender, in a kind of specific embodiment, such as Fig. 4 institutes
Show, circumferential direction of the blender along absorption tower 600 is evenly arranged with multiple so that each blender can stir the stream of same volume
Body avoids generating interference between flow field, also, the angle between the axis and horizontal line of each ceramet composite stirrer is
10 °, i.e. blender is inclined relative to horizontal setting, the axis of each ceramet composite stirrer horizontal plane projection with
Angle between the radial direction on absorption tower 600 is 4-12 °, i.e. projection of the axis of blender in residing 600 plane of absorption tower
Line and the angle at this between diameter line on absorption tower 600, if blender is pacified along 600 orthogonal diameter line of absorption tower
Dress, the slurries between blender and near 600 inner wall of absorption tower are just stirred less than, it may appear that precipitation fouling, if radial angle
It is excessive, it is likely to result in slurries and is rotated around center, generate precipitation in central area, only pass through preferred arrangement in blender
Afterwards, it just can guarantee there is no the deposition of solid particle in container, ensure the function and effect of blender.
In the alternative of the present embodiment, axial direction of the blender along absorption tower 600 be evenly arranged with it is multiple, on adjacent plane
It is uniformly staggered between the multiple ceramet composite stirrers being arranged.It is stirred by the axial setting multilayer along absorption tower 600
Mix device.Preferably, blender is arranged two layers, the effect of lower layer's blender be to prevent in absorption tower 600 slurries deposition, fouling or
Block so that the desulfuration byproduct through peroxidization can uniformly, smoothly enter dewatering system and complete entire technique stream
Oxidation spray gun is arranged in the top of journey, upper mixer, and oxygen is blasted from oxidation spray gun to 600 stock tank of absorption tower when desulphurization system is run
Change air, the effect of upper mixer is to enhance the diffusion of oxidation air, promotes the oxidation of calcium sulfite, it is ensured that at any time
The calcium sulfite generated by neutralization reaction can be substantially oxidized into dihydrate gypsum.The desulphurization system of double-layered stirrer is set,
Since two layers of mixer function is relatively independent, in simple system of the technical aspect compared with setting single layer blender, relatively set in terms of operation
The system for setting single layer blender is relatively reliable.
Since blender is usually installed by the take over 610 being welded on absorption tower 600, the diameter on absorption tower 600
Larger, tower wall is relatively thin, and the weight of blender is larger, in blender high speed rotation, will produce prodigious torsion and bending force,
If 610 rigidity of take over is inadequate, vibration is generated during blender can be made to operate, destroys the performance of mechanically-sealing apparatus 400.This implementation
In the alternative of example, as shown in figure 5, take over 610 is connected with the side wall on absorption tower 600 by stiffener plate 620.Pass through setting
Stiffener plate 620 improves the rigidity of take over 610, ensure that the stable operation of blender.
Since there are foulants for 600 stock tank liquid level of absorption tower to slurries spraying layer, when the foulants such as crystal of calcium sulfate collapse,
Area is big, quality weight, and the impact force of generation is big, often causes the things such as 400 damage of blender mechanically-sealing apparatus, bending shaft
Therefore cause desulphurization system can not normal operation, in a kind of specific embodiment, as shown in fig. 6, being provided in absorption tower 600
Backplate 630, backplate 630 are set to the top of blender, and backplate 630 is cellular grid backplate 630, also, backplate 630 is to close
The direction of agitating paddle 100 is obliquely installed.Cellular grid backplate 630 has fragmentation, crystallization hardness, the higher calcium sulfate of density
Crystallization falls off crash into slurry pool after remain to keep higher kinetic energy, and cellular grid backplate 630 and the side that crystallizes the object that collapses and contact
Mouth face, contact area is small, and when the two bumps against, crystallization crushing effect is good, the most broken fragment of crystal of calcium sulfate
It falls into through cellular grid backplate 630 in the slurry pool of lower section, and is pushed by blender, avoid nearby heaping, influence to stir
Device is run.Backplate 630 is obliquely installed, and the larger crystal of calcium sulfate that can not be crushed can then slide to 600 center of absorption tower with inclined-plane
Slurry pool, protect blender not smashed.
Finally it should be noted that：The above various embodiments is only to illustrate the technical solution of the utility model, rather than limits it
System；Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should
Understand：It still can be with technical scheme described in the above embodiments is modified, either to which part or whole
Technical characteristic carries out equivalent replacement；And these modifications or replacements, this practicality that it does not separate the essence of the corresponding technical solution are new
The range of each embodiment technical solution of type.
