Abstract
The agitating device of the utility model discloses a kind of suitable for ammonia desulfurizing process ammonium sulfate slurries, absorption tower bottom cavity are equipped with several nozzles, and hydrojet is converged from absorption tower bottom, the circulated sprinkling after slosh pump.For absorption tower prime cement liquid power is provided by disturbance pump, so that serum recycle and spraying from nozzle, provide hydraulic agitation for absorption tower prime cement liquid, solved the problems, such as in tower in saturated crystallization technique desulfurizing tower that ammonium sulfate agglomerates and block.Meanwhile the hydraulic agitation of the utility model, mass transfer problem when ammonium sulfate crystallization is effectively improved, compared with using Gas Stirring mode, ammonium sulfate crystallization is bigger.The utility model has the advantages of simple structure, easy to use, and production, maintenance cost are low, and using effect is good, has very strong practicability and wide applicability.
Description
Technical field
The utility model relates to a kind of agitating devices, and in particular to one kind ammonium sulfate slurries suitable for ammonia desulfurizing process
Agitating device.
Background technique
Ammonia desulfurizing process is used to remove sulfur dioxide in gas, wherein in tower saturated crystallization technique because can be abundant
Using the heat of flue gas, plant investment is few and is widely used.But with the raising of ammonium sulfate concentration, a large amount of sulfuric acid
Crystalline ammonium is precipitated, and is easily formed and is agglomerated in desulfurization tower bottom, and the blocking for causing down cycles to pump influences flue gas cool-down effect.
CN100428979C " crystallization inside tower ammonia desulfurizing process and device " is proposed arranges gas distribution in desulfurizing tower
Pipe is stirred using ammonium sulfate slurries of the oxidation wind tail gas to cooling enriching section.But this agitating mode is used, with analysis
Volume of ammonium sulfate out increases, and the increase of enriching section solid content, mixing effect is gradually deteriorated, and ought especially have portion gas distribution hole
After blocking, inevitably in tower the case where ammonium sulfate agglomeration.
Summary of the invention
To solve the deficiencies in the prior art, the purpose of this utility model is to provide one kind to be suitable for ammonia desulfurizing process
In, effectively solve the agitating device of saturated crystallization ammonium sulfate agglomeration blocking in tower.
In order to achieve the above objectives, the utility model adopts the following technical solutions:
A kind of agitating device of the ammonium sulfate slurries suitable for ammonia desulfurizing process, absorption tower bottom cavity are equipped with several nozzles,
Hydrojet is converged from absorption tower bottom, the circulated sprinkling after slosh pump.
Said nozzle is oriented tower bottom.
Said nozzle is apart from tower bottom≤1.5m.
Flow >=0.5m of said nozzle3/min。
Area coverage≤6m of said nozzle2。
Above-mentioned slosh pump is at least one.
Said nozzle successively mutual staggered floor setting.
The utility model has the beneficial effect that
A kind of agitating device of the ammonium sulfate slurries suitable for ammonia desulfurizing process of the utility model, by disturb pump be
Absorption tower prime cement liquid provide power so that serum recycle and from nozzle spray, provide hydraulic agitation for absorption tower prime cement liquid, solution
In tower in saturated crystallization technique desulfurizing tower the problem of ammonium sulfate agglomeration blocking.Meanwhile the hydraulic agitation of the utility model, effectively
Mass transfer problem when improving ammonium sulfate crystallization, compared with using Gas Stirring mode, ammonium sulfate crystallization is bigger.
The utility model has the advantages of simple structure, easy to use, and production, maintenance cost are low, and using effect is good, has very strong reality
With property and wide applicability.
Detailed description of the invention
Fig. 1 is that a kind of structure of the agitating device of ammonium sulfate slurries suitable for ammonia desulfurizing process of the utility model is shown
It is intended to.
Attached meaning marked in the figure is as follows: 1, absorption tower, 2, disturbance pump, 3, nozzle.
Specific embodiment
Specific introduce is made to the utility model below in conjunction with the drawings and specific embodiments.
A kind of agitating device of the ammonium sulfate slurries suitable for ammonia desulfurizing process, 1 bottom cavity of absorption tower are equipped with several directions
The nozzle 3 of tower bottom, the nozzle 3 converge apart from tower bottom≤1.5m, hydrojet (slurries) from 1 bottom of absorption tower, and spray is recycled after slosh pump
Leaching, area coverage≤6m2, flow >=0.5m3/min。
Preferably, nozzle 3 may be configured as successively mutual staggered floor, and the slurries stacked gradually are provided for slurries and gush power, and is adjacent
Slurries between nozzle 3, which form better fluid power staggered floor and turn over, to be gushed.
Material is antiwear and anticorrosive material, preferably silicon carbide.
Embodiment:
Disturbance pump 2 outside two towers is set for the enriching section of the desulfuration absorbing tower 1 of diameter 8m, pump discharge is 420 m3/h.Pump
Import be connected with desulfurizing tower enriching section bottom, outlet connects 14 nozzles 3 in tower through pipeline, the spraying layer that nozzle 3 forms
Height is 1.5m, 3 material silicon carbide of nozzle, each 3 area coverage 3.6m of nozzle2。
Operation after two months, stops tower inspection, desulfurizing tower enriching section is without buildup.
The basic principles and main features and advantage of the utility model have been shown and described above.The technical staff of the industry
It should be appreciated that above-described embodiment does not limit the utility model in any form, it is all by the way of equivalent substitution or equivalent transformation
Technical solution obtained, all falls in the protection scope of the utility model.
