Description
Technical field
The invention belongs to purification technique field, and in particular to a kind of to heat the combined type knot formed with continuous freezing
Brilliant device.
Background technology
Crystallization process is exactly constantly to form the process that nucleus and nucleus are constantly grown up.The type of crystallizer is a lot, by molten
The method that liquid obtains hypersaturated state can divide crystallizing evaporator and cooler crystallizer；Can decomposition mother solution circulation crystallization device by the type of flow
And magma（That is the mixture of mother liquor and crystal）Circulation crystallization device；It can divide continuous crystalizer and periodic crystallisation device by mode of operation.
Solution degree of supersaturation is the motive force that crystal crystallizes out from solution, and the size of degree of supersaturation directly affects nucleus
Form the speed with rate of crystalline growth.Freezing and crystallizing device is to produce degree of supersaturation, refrigeration crystallization process by reducing temperature
Cryogenic temperature control is extremely important.Traditional freezing and crystallizing device usually uses the single kettle type crystallizer of belt stirrer, and crystallizer is set
Chuck or inner coil pipe cool, and for temperature control near a numerical value, agitating device makes brilliant liquid constantly circulate, low in crystallizer
Caused nucleus is constantly grown up in warm solution, and crystallizer is discharged after reaching the granularity of needs.Also, in continuous crystallization process
In, the speed of growth of crystal is generally unhappy in crystallizer, does not reach desired crystal size, it is necessary to set single aging device,
Crystal is stayed for some time wherein continued growth, aging device is discharged after reaching desired particle diameter.This crystallization apparatus is present
Problems with：
1) in a crystallizer, it is typically only capable to control a crystallization temperature, is not easy effectively control crystallization degree of supersaturation,
So as to can not effectively control the formation of nucleus and the speed of rate of crystalline growth；
2) kettle type crystallization device is cooled by chuck or inner coil pipe, and heat exchange area is small, heat exchange amount is little, is not suitable for big
Rule
Die device；
3) usually cause product grains size uneven because cooling velocity is uneven, the fine grain shadow that crystallization process is formed
Follow-up separation of solid and liquid is rung, or even causes system jams；
4) the usual specification of kettle type crystallization device of belt stirrer is smaller, and disposal ability is limited, large-scale freezing and crystallizing separation
Device is, it is necessary to by the way of the kettle type crystallization device of multiple belt stirrers is in parallel, and number of devices is more, and floor space is big；
5) in continuous crystallization process, the growth residence time of crystal is short in crystallizer, does not reach desired crystal grain
Degree makes brilliant liquid be stayed for some time in aging device, it is necessary to set single aging device, allows crystal continued growth；
6) because aging device is separately provided, make that crystallization apparatus number of devices is more, and floor space is big.Also, low temperature crystallization liquid
The pipeline of aging device is flowed to from crystallizer, in fact it could happen that flow is low, continue crystallization, pipeline turn round situations such as, so as to cause pipeline
Block, influence the continuous operation of device.
7) discharging opening is located at kettle type crystallization device bottom, and the crystal of precipitation easily causes discharging opening blocking after being deposited to bottom.
The content of the invention
The invention provides a kind of combined type barium sulfate crystallization apparatus, can comprehensively utilize heating evaporation and improve solution concentration
Accelerate and improve the advantage of crystallization process and completeness with continuous coo1ing, longtime running is stable, service life length, and operation side
Just safety, technological ability are good.
A kind of combined type barium sulfate crystallization apparatus, servomotor are fixed on ground, and the servomotor is connected with water pump,
And water pump is driven to rotate at a high speed, the input connection main body of water pump, output end then connects heat exchanger, the heat exchanger
Upper end is mounted with feed liquid delivery pipe, and the material flow after supercooling enters in main body, and the upper end of the main body passes through water vapour pipeline
It is connected with condenser, the upper end of condenser installs non-condensable gas export, and lower end is then delivery port.The lower end of aforementioned body and water
Pump is connected, and feed liquid is delivered into crystallisation by cooling tank body by concentrating feed liquid delivery pipe on suitable opportunity and cooled down, institute
State the inside installation crystallisation by cooling component of crystallisation by cooling tank body and be connected with crystallizer.The crystallisation by cooling component includes one-level
Cooling spiral, dividing plate and two level cooling cavities, the one-level cooling spiral are arranged on the upper end of the inside of crystallisation by cooling tank body,
It is filled with cooling water between crystallisation by cooling tank body cavity, and the dividing plate divides one-level cooling spiral and two level cooling cavities
Open.
The pitch of the one-level cooling spiral is equal to its caliber, increases its connecing between cooling liquid as far as possible with this
Contacting surface is accumulated.
The remarkable result of the present invention is：
1st, structure and working principle of the present invention is simple, it is easy to accomplish, personnel's participation depth is low, the crystallization for barium sulfate
Journey, it is easy to implement the automated production of factory.
2nd, the factor of sulfuric acid yield of barium is influenceed in addition to raw mineral materials and the quality of calcining and immersion, is also ceased with crystallization process
Manner of breathing closes, and theoretically the temperature of analysis barium sulfate solution is lower, solution concentration is more big more is advantageous to crystallize, and the present invention is first led to
Cross steam to heat solution, it is reduced the content of moisture after seething with excitement, then cool down acceleration crystallization process again, therefore have more thorough
Bottom and efficient crystallization process.
