Abstract
The invention discloses a kind of continuous production vacuum cooling crystallizer.It includes a crystallisation chamber, and guide shell, a forced circulation pump are circulated in one；Top sets indirect steam to export, and is cooled down by vacuumizing mode；Forced circulation pump is arranged on crystalliser feet, and slurry reaches shwoot near liquid level by the way of being circulated in bottom by guide shell.The present invention using the bottom of big flow force in circulation shwoot cooling, reduce in Conventional batch low production efficiency and external circulation process easy fouling, the probability of blocking in circulation pipe, heat exchanger；Crystallisation chamber uses top straight tube, the structure of bottom cone cylinder, it can realize that the crystal salt for completing in crystallisation chamber to separate out and supernatant efficiently separate, cone cylinder sets different discharging openings simultaneously, with continuous production, the equipment cycle of operation extends, and stable operation is easy to control, can meet the characteristics of different grain size discharging demand.
Description
Technical field
The invention belongs to vacuum cooled crystallization technique field, the more particularly, to industry such as nickel sulfate, cobaltous sulfate, ammonium chloride
Highly concentrated brine-cooled crystallizer.
Background technology
In traditional cooling technology in the fields such as nickel sulfate, cobaltous sulfate, ammonium chloride, the method for use has following two：1）
Circulating water is carried out using jacketed band stirred crystallization kettle；2）Cooling is forced using the crystallizer of outer cooling heat exchanger.It is previous
Kind method uses intermittent cooling, and production efficiency is low, and easily being lumpd in kettle wall influences heat transfer, it is necessary to which frequent clean, causes to produce
Cycle is short.Later approach easily causes outer cold heat exchanger and blocks fouling, influences heat transfer efficiency, while grain size number is thinner, Gu
Liquid separation is more difficult.
The content of the invention
It is an object of the invention to provide a kind of continuous production vacuum cooling crystallizer, equipment collection cooling, crystallization, sedimentation
In one, can solve the problems, such as equipment, heat exchanger tube blocking caused by frequently brush tank, cleaning, have equipment continuously run and
The cycle of operation is grown, and process stabilizing is easy to operation, while can meet to produce the features such as varigrained crystal salt requires.
The technical scheme of invention：
A kind of continuous production vacuum cooling crystallizer, it is characterised in that：Including crystallisation chamber, it is interior circulation guide shell, forced circulation pump,
Indirect steam outlet, manhole are provided with the top of crystallisation chamber, cylinder body outer wall sets multiple observation visors, and lower cone section is provided with feed liquid and entered
Mouth, multiple slurry outlets, bottom is provided with evacuation port；Interior circulation guide shell sets the support tube with crystallisation chamber.
Described crystallizer is circulating cooling crystallizer in pressure.
Interior circulation guide shell is installed inside described crystallisation chamber.
Crystalliser feet uses forced circulation pump.
Compared with traditional equipment, the present invention has the advantages that：1）Using vacuum cooled, pass through the strong of big flow
Circulation shwoot desuperheat in system, saliferous feed liquid is avoided in common process in heat exchanger the problem of easy Crystallization Plugging, 2）Crystallization
Room uses the structure type of top straight tube lower cone section, it is possible to achieve completes to separate out crystal grain and supernatant in crystallisation chamber
Efficiently separate, eliminate settler, while different position discharges can be selected according to different Grained Requirements；3）It can realize
Continuous production, the equipment cycle of operation extend, and stable operation is easy to control.
Brief description of the drawings
Fig. 1 is inventive structure schematic diagram.
In figure：1- crystallisation chambers, the interior circulation guide shells of 2-, 3- forced circulation pumps, 4- indirect steams outlet 4,5- people
Hole, 6- observation visors, 7- slurry outlets, 8- liquor inlet, 9- bottoms are provided with evacuation port；Circulation guide shell and crystallization in 10-
The support tube of room.
Embodiment
Below in conjunction with the accompanying drawings, the present invention is further elaborated.
As shown in figure 1, a kind of continuous production vacuum cooling crystallizer, including crystallisation chamber 1, interior circulation guide shell 2, force to follow
Ring pump 3.Wherein, the top of crystallisation chamber 1 is provided with indirect steam outlet 4, manhole 5, and cylinder body outer wall sets 3 observation visors 6, lower cone section
3 slurry outlets, 7,3 liquor inlet 8 are provided with, bottom is provided with evacuation port 9；Interior circulation guide shell 2 is set and crystallisation chamber
Support tube 10.
Crystallizer is circulating cooling crystallizer in pressure.Interior circulation guide shell 2 is installed inside crystallisation chamber.Crystalliser feet
Using forced circulation pump 3.
The present invention is applied in cobalt sulfate cooling and crystallizing process, and specific operation process is as follows：By concentration be 38%~
42% 70~80 DEG C of cobalt sulfate solutions are the liquor inlet mouth that raw material enters the vacuum cooling crystallizer, circulate guide shell inside
It is interior to be contacted with a large amount of low-temperature circulating feed liquids, enter together near crystallisation chamber liquid level under the drive of bottom forced circulation pump, outside
Shwoot cooling separates out crystal under the negative pressure draft of vavuum pump, controls feed temperature in crystallizer to maintain 38~42 DEG C.Pass through knot
The straight tube and lower cone section of brilliant device, variable grain solid falls into lower cone section different parts in infall process, different by opening
Slurry outlet valve, cobalt sulfate crystalline product of the required particle diameter in 0.7~2mm can be obtained.
