Description
Technical field
The utility model relates to a kind of crystallizing tank, specifically a kind of crystallizing tank with pellicle.
Background technology
Crystallization is the process that solute is separated out from solution, more common in Chemical Manufacture, generally appears in the process of product preparation and purification.Crystallization process produces a large amount of solids of sedimentation, is deposited on the bottom of crystallizer, easily blocks or stick with paste discharge gate and the blow-off valve of dead bottom, makes the mother liquor in crystallizer and solid be difficult to discharge, has a strong impact on normally carrying out of production.If the tapping process after lithium hexafluoro phosphate crystallization is the difficult problem that fluorine chemical is produced always, after lithium hexafluoro phosphate crystallization, be deposited on discharge gate and the blow-off valve of device bottom blocking or the dead bottom of paste, need during tapping to pour out mother liquor by after equipment upset, each upset needs artificial unloading and links mother liquor pipe and refrigerant pipe, operates extremely loaded down with trivial details; Meanwhile, whole process is in extreme danger, and the hydrofluoric acid in mother liquor has strong corrosivity and toxicity, will cause catastrophic consequence once reveal to human body, therefore overturns tapping process and there is great potential safety hazard.The too large and crystallize out of material cycles of concentration in evaporation process, makes the fouling of heater heat exchanger tube, blocking and cause evaporation equipment cannot continue to run.But, for solubility along with the little material of variations in temperature, after under the state that reaches capacity after evaporimeter discharging, the crystal that crystallisation by cooling is separated out is less, and a large amount of separation mother liquors can be produced when centrifuge Separation of Solid and Liquid, this part mother liquor understands outside distribute heat again after cooling, separation in the comparatively long circulating route of mother liquor tank, returns when vapo(u)rization system is evaporated and needs, again to its heating, to make the waste of whole system to heat energy more.
Utility model content
The purpose of this utility model is to provide a kind of crystallizing tank with pellicle, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of crystallizing tank with pellicle, comprise vapour liquid separator and crystallizer, vapour liquid separator is connected to the top of crystallizer, and vapour liquid separator is provided with top steam drain and middle part charging aperture, crystallizer is provided with bottom discharge mouth, and bottom discharge mouth is positioned at the tip place of crystallizer conical lower portion; Gas phase pipe is communicated with between described crystallizer and vapour liquid separator, the external diameter of vapour liquid separator is less than the external diameter of crystallizer, crystallizer has and the shoulder be connected bottom vapour liquid separator, and one end of gas phase pipe is installed on shoulder, and the other end of gas phase pipe is installed on the sidewall of vapour liquid separator; The middle part charging aperture of vapour liquid separator and the middle part liquid outlet of crystallizer are in the same side, the bottom of vapour liquid separator has the mesotube stretched in crystallizer, mesotube end is connected with and is provided with water distributor, water distributor is laid with several water-locators, water-locator comprises the first shower nozzle and the second shower nozzle; Be provided with outlet pipe in described crystallizer, outlet pipe passes crystallizer outside, outlet pipe and the airtight setting of crystallizer, and upwards connects several spiral heat exchange tubes; Spiral heat exchange tube upper end connects water inlet pipe, passes crystallizer outside, water inlet pipe and the airtight setting of crystallizer on the left of water inlet pipe; Described crystalliser feet is provided with water treatment plant, is provided with pellicle below water treatment plant.
Further, described bottom discharge mouth is equipped with blow-off valve.
Further, collecting-tank is provided with below described pellicle.
Compared with prior art, during utility model works, the pressure due to mother liquor makes the moisture penetration in mother liquor go out pellicle, falls into collecting-tank, further improves crystallization effect, has saved production cost, has added economic benefit; The utility model is provided with spiral heat exchange tube, increases heat exchange area, and crystallization effect is good, pellicle is provided with in addition above collecting-tank, can moisture in filtrated stock, during utility model works, first shower nozzle and the second shower nozzle combinationally use, and mother liquor is collided mutually, splashes, water distribution is even, spray area is large, do not stay dead angle, thus reach better heat transfer effect, compact conformation, easy to operate, safeguard easily; Be provided with blow-off valve, during discharge, do not need tipping arrangement and dismounting pipeline, simple to operation, greatly improve operating efficiency, save manpower and materials, the leakage of mother liquor during operation, can not be caused, safe and reliable, be applicable to promoting the use of.
