Description

The salt chemical engineering reactor

The utility model relates to a kind of reactor of chemical reaction, particularly a kind of salt chemical engineering reactor that relates to the salt chemical engineering conversion reaction.

In the prior art, the principle of conversion reaction is in the salt chemical engineering: in polynary mutual system phase diagram, different material is different solubility under different conditions, according to unbecoming solution principle, utilize common ion effect, add and to have homo-ion solid or liquid salt in feed liquid, the component of more difficult dissolving is separated out in the solution, solid that adds or liquid salt dissolve in feed liquid and replace the salt of being separated out mutually, be that each material concentration difference in the reaction feed liquid just is in different phase regions, by drop into homo-ion liquid phase or solid-phase material in feed liquid, the composition and the reaction condition of control feed liquid can make it decompose in feed liquid, crystallization, produce mutual conversion reaction, make the point mutually of required product be transferred to the crystallization phase region, become the solid phase of separating out, again it is separated from feed liquid.In the process of decomposition, reaction and the crystallization of material, prior art does not have specialized apparatus, generally all adopts common tank diameter or stirred vessel.The problem of its existence is: the solid phase product granularity that obtains is tiny, postprocessing working procedures difficulties such as dehydration, drying; Insoluble matters such as the mud that contains in the raw material, sand are difficult to remove, and product quality is difficult to guarantee; The material yield is also low.

The purpose of this utility model is to provide a kind of pot type salt chemical engineering reactor that is provided with the salt chemical engineering conversion reaction special use of reaction, overflow, separation setting at the deficiencies in the prior art.

The purpose of this utility model is to be realized by following technical scheme.The utility model is a kind of salt chemical engineering reactor, be characterized in that it is provided with the tank body of a band bearing, middle part in tank body, be provided with on one, the guide shell of following perforation, agitating device is housed in the guide shell, the guide shell top is provided with the dog-house that leads to the tank body outside, the periphery of the middle and upper part guide shell in tank body, be equipped with, the flow isolating cylinder of following perforation, the difference in height of guide shell and flow isolating cylinder upper edge hole is not less than half of guide shell radius, is provided with the overflow launder of annular on the top of tank body, and the overflow bead of overflow launder is lower than the upper edge of flow isolating cylinder, the bottom of overflow launder is provided with leads to a jar outer overfall, and the bottom of tank body is provided with leads to a jar outer discharging opening.

Like this, form several zones in the salt chemical engineering reactor: the guide shell top is a material charging region; Flow isolating cylinder is reaction zone with in, and reaction zone comprises that guide shell is with interior zone; Zone between flow isolating cylinder and the tank body is the sedimentation overflow area; Guide shell is discharge zone with the lower part.Material and feed liquid enter reaction zone by material charging region continuously equably, and decomposition, crystallization produce mutual conversion reaction and react to each other in reaction zone, mixer carries out the complete mixing flow continuous stirring simultaneously, control feeds intake and mixing speed, makes crystallization rate controlled, helps making crystal to be grown up.Complete mixing flow stirs and can prevent that the local degree of supersaturation of generation is excessive in the crystal region, reduces the generation of a large amount of nucleus, also impels grain growth.The solid phase salt that solid phase salt of separating out or reaction generate is as the crystallization reaction that circulates in the feed liquid of reaction zone under the effect of crystal seed mixer in guide shell, crystal is grown up behind certain particle size, under the gravity effect, overcome fluid to upthrust, be deposited in the slip of reaction zone below discharge zone, and contain the mother liquor of part particle diameter than small crystals and other impurity, upwards overflow reaction vessel from the peripheral sedimentation overflow area of reaction zone.The mother liquor that overflows uses as circulating mother liquor after clarifying.According to Stokes' law, square being directly proportional of the sinking speed of suspended particles and particle proportion and particle diameter in the aqueous solution like this, guarantees that the salt crystallization that reaches certain particle size sinks, and the granule overflow is gone out, and nucleus quantity is controlled simultaneously.The slip that will contain the greater particle size crystal below reaction zone is emitted from the discharging opening of tank body bottom, sloughs mother liquor, and drying obtains required solid phase salt crystal.

The purpose of this utility model can also further reach by following scheme.Aforesaid salt chemical engineering reactor is characterized in that the power motor of agitating device is contained in the tank body outside.Relatively be convenient to maintenance.

The purpose of this utility model can also further reach by following scheme.Aforesaid salt chemical engineering reactor, the top that is characterized in tank body is cylinder, the bottom is up big and down small infundibular body.Guaranteeing that enough reaction compartments are arranged at top, the bottom crystal accumulation together, discharging is more convenient.

Compared with prior art, the utility model utilizes fluid mechanics principle at the characteristics of conversion reaction in the salt chemical engineering, reasonable in design.The solid phase product crystal granularity of producing is big, and postprocessing working procedures such as dehydration, drying are simple; Insoluble matters such as the mud that contains in the raw material, sand are removed substantially, the purity height of product, and quality is guaranteed; The material yield also is greatly improved.
