Description
Technical field
The utility model belongs to pickler field, relates in particular to a kind of liquid level and regulates crystallization kettle.
[
background technology]
Industrial crystallization equipment mainly divides two kinds of cooled and vaporation-types, and the latter divides atmospheric evaporation formula and vacuum evaporation type according to evaporation operation pressure again.Because vacuum evaporation efficiency is higher, so vaporation-type crystallizer be take vacuum evaporation as main.The crystallization of specific objective product specifically selects the crystallizer of which kind of type mainly according to the solubility curve of target product, to determine.If the solubility with temperature of target product raises and enlarges markedly, can adopt cooling knot product device or evaporation knot product device, otherwise can only select evaporation type knot product device.
The cooling raio surface area of internal-circulation type crystallizer is less, and knot product speed is lower, is unsuitable for extensive crystallization operation.In addition, because the temperature of knot product wall is minimum, so solution degree of supersaturation is maximum. on wall, easily form brilliant dirt, affect heat transfer efficiency.Outer circulation type crystallizer is cooling by external heat exchanger, due to forced circulation, and solution high velocity stream over-heat-exchanger surface, less by the solution temperature difference of heat exchanger, heat-exchanger surface is difficult for formation product dirt, and exchange efficiency is higher, can long period continuous operation; But must select suitable circulating pump, in order to avoid the wearing and tearing of suspension product body are broken.Saturated solution is logical people from crystallizer bottom, crystallization in the mobile process that makes progress, the downward sedimentation of crystal of separating out.Because bottom flow velocity is higher, only have bulky grain crystal can be deposited to bottom and discharge.Employing chuck is cooling, and the volume of knot product device is less, is applicable to produce continuously on a small scale.
Crystallizing evaporator forms by tying product device main body, vaporization chamber and external heater.Solution is sent into vaporization chamber evaporation and concentration after outer loop heating, reaches hypersaturated state, by centre pipe, drops in crystalline growth groove.In knot product growths groove, the fluid crystallization mobile time that makes progress is constantly grown, and large particle crystal generation sedimentation, discharges product magma (mixture of crystal and solution is called magma) from bottom.Vaporization chamber is connected with vavuum pump, can carries out vacuum insulation evaporation.
