Description
Technical field
The present invention relates to a kind of evaporation separation equipment, be specifically related to a kind of evaporative crystallization integration apparatus.
Background technology
In existing evaporation crystallization equipment, evaporation equipment and crystallizer are separate, carry out respectively evaporation and concentration and crystal and separate out, and first material are concentrated into the maximum concentration of setting in evaporation equipment, generally namely material are concentrated to saturation state; Then the mass transport after concentrated to the crystallizer of setting up is separately carried out to crystallization.The reason that above-mentioned evaporative crystallization separates is mainly to worry the too large and crystallize out of material cycles of concentration in evaporation process, makes the fouling of heater heat exchanger tube, obstruction and causes evaporation equipment cannot continue operation.But, for solubility along with the little material of variations in temperature, after reaching capacity under state from evaporimeter discharging, the crystal that crystallisation by cooling is separated out still less, and can produce a large amount of separated mother liquors when centrifuge Separation of Solid and Liquid, this part mother liquor again to can outside distribute heat in the longer circulation route of mother liquor tank, need to, again to its heating, make whole system more to the waste of heat energy when returning vapo(u)rization system and evaporating after cooling, separation.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides the evaporative crystallization integration apparatus that a kind of circulation route is short, heat-energy losses is few, crystalline rate is high.
Technical scheme: for solving the problems of the technologies described above, evaporative crystallization integration apparatus provided by the invention comprises vapour liquid separator and crystallizer, vapour liquid separator has top steam drain and middle part charging aperture, crystallizer has middle part liquid outlet and bottom discharge mouth, vapour liquid separator is connected to the top of crystallizer, the bottom of vapour liquid separator has the central circulating tube stretching in crystallizer, is communicated with vapour phase pipe between crystallizer and vapour liquid separator.
As preferably, for the ease of manufacturing, the external diameter of vapour liquid separator is less than the external diameter of crystallizer, and crystallizer has the shoulder being connected with vapour liquid separator bottom, and one end of vapour phase pipe is installed on shoulder.
As preferably, in input crystallizer, input the interference of material to middle part liquid outlet, the outlet of central circulating tube is positioned at the below of middle part liquid outlet.
As preferably, for the ease of the discharge of crystallizer bottom crystal, the bottom of described crystallizer is tapered, and described bottom discharge mouth is positioned at the end of described taper.
As preferably, the interference for fear of vapour phase pipe to input material, the other end of vapour phase pipe is installed in the opposing sidewalls of vapour liquid separator middle part charging aperture.
As preferably, for the ease of exterior line is installed, the middle part charging aperture of vapour liquid separator and the middle part liquid outlet of crystallizer are in the same side.
Beneficial effect: the structure that evaporative crystallization integration apparatus of the present invention adopts central circulating tube and vapour phase pipe that vapour liquid separator and crystallizer are connected, compared to existing technology, the circulation route of material in equipment is shorter, in crystallizer, utilize the layering that in central circulating tube, liquid stream, heat exchange and Action of Gravity Field produce supernatant and crystal downwards, avoid the fouling in circulation to stop up, made evaporative crystallization be continued to carry out.And final crystal water content of discharging is few, reduced the heat-energy losses that separated mother liquor heating is caused, there is higher crystalline rate.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention;
In figure: 1 vapour liquid separator, 2 crystallizers, 3 top steam drains, 4 middle part charging apertures, 5 central circulating tubes, 6 vapour phase pipes, 7 middle part liquid outlets, 8 bottom discharge mouths.
The specific embodiment
Embodiment: the structure of evaporative crystallization integration apparatus provided by the invention as shown in Figure 1, comprise vapour liquid separator 1 and crystallizer 2, vapour liquid separator 1 is connected to the top of crystallizer 2, vapour liquid separator 1 has top steam drain 3 and middle part charging aperture 4, crystallizer 2 has middle part liquid outlet 7 and bottom discharge mouth 8, and bottom discharge mouth 8 is positioned at the place, tip of crystallizer conical lower portion.The middle part charging aperture 4 of vapour liquid separator 1 and the middle part liquid outlet 7 of crystallizer 2 are in the same side.The bottom of vapour liquid separator 1 has the central circulating tube 5 stretching in crystallizer 2, the outlet of central circulating tube 5 is positioned at the below of middle part liquid outlet 7, between crystallizer 2 and vapour liquid separator 1, be communicated with vapour phase pipe 6, the external diameter of vapour liquid separator 1 is less than the external diameter of crystallizer 2, crystallizer 2 has the shoulder 2-1 being connected with vapour liquid separator 1 bottom, one end of vapour phase pipe 6 is installed on shoulder, and the other end of vapour phase pipe 6 is installed in the opposing sidewalls of vapour liquid separator 1 middle part charging aperture 4.
During use, material enters vapour liquid separator 1 after evaporation and concentration, and after flash distillation, indirect steam is discharged to next effect body from top steam drain 3, and material enters the bottom of crystallizer 2 by central circulating tube 5, large crystal sinks to the bottom of taper, and trickle crystal slowly rises, and constantly grows up.The crystal of growing up sinks to the bottom of crystallizer 2 again, the top of crystallizer 2 is supernatants, supernatant is recycled to and in vapour liquid separator 1, is realized continuous evaporative crystallization by middle part charging aperture 4 again after middle part liquid outlet 7 is transported to firing equipment heating, because supernatant contains very fine particle, in heating process, non flouling behaviour and obstruction heating tube pipeline, can carry out evaporation process continuously.The crystal that is deposited to crystallizer 2 bottoms is discharged from crystallizer 2 by bottom discharge mouth 8, due to the crystal water content little (concentration reaches more than 70%) of discharging, the problem that need reheat with regard to a large amount of low temperature mother liquors of having avoided external crystallisation by cooling to produce, reduced the consumption of heat energy, made system more energy-conservation.
