Technical field
The utility model relates to field of chemical equipment, particularly relates to a kind of agitating device for gas-liquid mixed reactor.
Background technology
When chemical field carries out material reaction, often relate to mixing of materials, usually by stirring, material is fully mixed, the uniform mixture of height of formation.
In the prior art, for the solution polymerization process preparing rare-earth isoprene rubber, conventional raw material pre-compounding process many employings static mixer carries out.But because static mixer exists fluid stagnation district usually in exit, therefore the velocity flow profile of material is uneven, and disturbance effect is poor, causes mixed effect not ideal enough.
At present, usually also adopt the stirring autoclave blender of structure relative complex as raw material premixed device.Wherein, under the effect of paddle, the turbulent extent of material strengthens, and causes mixed effect to be strengthened.But the characteristic due to paddle causes the Flow Field Distribution in still uneven, and easily there is the larger mixing dead band of volume, cause final mixed effect also not ideal enough.In addition, the structural design of stirred tank is the key factor affecting premixing effect.In pre-compounding process, both required catalyst high uniformity dispersion in material system, required again that the upper and lower mixing in whole stirred tank was even as much as possible.Traditional stirred tank often can not reach this requirement.
Also having is together in series static mixer and stirred tank carries out the premixing process of raw material premix.Publication number is that the Chinese patent literature of CN201415984Y discloses a kind of premixing device for rare-earth isoprene rubber production, comprising the pipeline super mixer be in series and premix still.Before entering polymeric kettle, polymerisation material carries out premix in this pre-mixing apparatus, the microcosmic Homogeneous phase mixing of height can be reached, thus improve the catalytic efficiency of catalyst, decrease the degree of branching of product, make the distribution of molecular weight more even, finally improve the product quality of isoprene rubber.But the shortcoming of this pre-mixing apparatus is, the mean residence time of material in premix still is longer, and then after the polymerization reaction kettle reaction of multiple stage series connection, final conversion ratio can only reach 85-90wt%.
Existing gas-liquid mixed arranges air inlet at reactor bottom usually, and carries out constantly stirring to accelerate gas-liquid mixed to reactant with agitator, but bubble is also unmixed in a large number has just risen to liquid surface, and mixed effect is poor.

Preferably axially the quantity of arm is 4 ~ 6 further.
As preferably, the axis of described agitating fins arm is vertically uniformly distributed.
Described agitating fins is for agitated liquid on the one hand, is smash bubble on the other hand, gas is mixed with liquid evenly.The described agitating fins vertically axis of arm is uniformly distributed and can ensures that the liquid at each position around axial arm all obtains uniform stirring.
As preferably, described agitating fins is projected as ellipse along its thickness direction.
Described venthole matches with agitating fins.
As preferably, the axis of described venthole arm is vertically uniformly distributed.
Described venthole vertically arm axial distribution is more conducive to gas-liquid mixed.
As preferably, described venthole quantity and each venthole corresponding with agitating fins is positioned at below corresponding agitating fins.
As preferably, the radially projecting of described venthole arm is vertically triangle, and this leg-of-mutton summit is towards stiffener.
As preferably, described rest base is fixed with beam.
During machine operation, vibration is comparatively large, and agitator also can produce larger vibration when rotating in addition.Described beam is for reducing the noise produced by vibration.
Agitating device for gas-liquid mixed reactor of the present utility model, while stirring, paddle can be vented outward and produce bubble in liquid around, under the beating of agitating fins, air pocket is ground into minute bubbles, and minute bubbles more easily stop and are mixed into a step react for gas-liquid in a liquid.
