Abstract
The invention discloses a continuous concentration crystallization device. The continuous concentration crystallization device comprises a crystallization tower, a heater and a circulating pump, wherein the crystallization tower comprises a tower body, the tower body is provided with a liquid inlet in the tangential direction of the tower body, the upper portion and the lower portion of the liquid inlet form a vapor-liquid separating section and a crystallization section respectively, the vapor-liquid separating section is a blank pipe section, a demister is arranged at the top of the vapor-liquid separating section, a flow guide pipe used for enabling liquid to be concentrated to flow is arranged in a barrel of the crystallization section, the position, close to the bottom of the crystallization section, of the outlet end of the flow guide pipe is provided with a distributor so that the liquid to be concentrated can flow out from the side edges of the outlet end, a standing area is formed at the bottom of the crystallization section, a floatation area is formed outside the flow guide pipe, and a liquid outlet is further formed in the upper portion of the floatation area; the liquid outlet and the liquid inlet are communicated to form a loop through the circulating pump and a pipeline, and the heater is arranged on the circulating pipeline. The continuous concentration crystallization device is simple in structure, good in effect and capable of achieving continuous crystallization.
Description
Technical field
The invention belongs to chemical production technology and equipment technical field, relate generally to continuous condensing crystallizing device.
Background technology
Existing condensing crystallizing equipment generally by heater, separator, by be made up of stirring.Stir consumption of power on the one hand in process of production, also easily destroy crystal structure.On the other hand decrease flotation effect to crystal in crystal system owing to there is larger disturbance in separator, crystallization effect is bad.Equipment component can only carry out intermittent operation, increases operation easier, and the secondary vapour in concentration process does not have value.
Summary of the invention
Goal of the invention: for above-mentioned Problems existing and defect, the invention provides a kind of continuous condensing crystallizing device, structure simple effects is good, can realize continuous crystallisation.
Technical scheme: for achieving the above object, the present invention is by the following technical solutions: a kind of continuous condensing crystallizing device, comprise crystallizing tower, heater and circulating pump, described crystallizing tower comprises tower body, it is the inlet of tangential direction that described tower body is provided with tower body, the upper and lower of inlet is respectively vapor-liquid separation section and crystallized region, described vapor-liquid separation section is blank pipe section, and top is provided with demister, the mozzle for the liquid to be concentrated that circulates is provided with in the middle of the cylindrical shell of described crystallized region, this mozzle is near the bottom of crystallized region and the port of export is provided with distributor that liquid to be concentrated is flowed out from port of export side, the bottom of described crystallized region is for leaving standstill district, and mozzle outside is flotation area, and the top of flotation area is also provided with liquid outlet, form circulation by circulating pump and pipeline communication between described liquid outlet and inlet, and circulating line is provided with heater.
Preferably, described distributor is circular arc plate, thus when making to flow out from liquid from mozzle, avoids directly impacting the crystalline solid in the standing district bottom crystallized region.
Preferably, the top of described vapor-liquid separation section is also provided with indirect steam outlet, thus the indirect steam after can being separated everywhere is recycled.
Beneficial effect: compared with prior art, the present invention has the following advantages: reduce the energy resource consumption in production process, alleviates producers' labour intensity and reduces operating personnel; Equipment investment and floor space is reduced while improving the rate that comes into force; And quality and the stability of crystalline product can be guaranteed.

Fig. 2 is A-A direction top view in Fig. 1.
Wherein, inlet 1, gas-liquid separation section 2, crystallized region 3, demister 4, mozzle 5, distributor 6, flotation area 7, standing district 8, liquid outlet 9, indirect steam outlet 10.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.
As shown in Figure 1, a kind of continuous condensing crystallizing device, comprise crystallizing tower, heater and circulating pump, described crystallizing tower comprises tower body, it is the inlet of tangential direction that described tower body is provided with tower body, the upper and lower of inlet is respectively vapor-liquid separation section and crystallized region, described vapor-liquid separation section is blank pipe section, and top is provided with demister, the mozzle for the liquid to be concentrated that circulates is provided with in the middle of the cylindrical shell of described crystallized region, this mozzle is near the bottom of crystallized region and the port of export is provided with distributor that liquid to be concentrated is flowed out from port of export side, the bottom of described crystallized region is for leaving standstill district, and mozzle outside is flotation area, and the top of flotation area is also provided with liquid outlet, form circulation by circulating pump and pipeline communication between described liquid outlet and inlet, and circulating line is provided with heater.
During work, the liquid level of the liquid in crystallizing tower flushes with inlet substantially, liquid to be crystallized enters tower body inside from inlet tangential direction, isolate the gas of flash distillation, flash gas is sent as indirect steam can recycle as low grade heat source from the outlet at top, this process at utmost can reduce liquid and fly in circles and enter gas-liquid separation section, adopts tangential direction can reduce the effect of impacting and improving vapor-liquid separation simultaneously.Liquid after separation enters crystallized region with comparatively low velocity by mozzle, and under distributor effect near the port of export, liquid is flowed out from side surrounding, finally enter flotation area, larger crystalline particle is settled down to standing district and extraction under gravity, and less crystallization and solution are to flotation area ionized motion, finally squeeze into the further concentrate of heater through circulating pump together with fresh feed liquid.And so forth, thus realize continuous crystallisation.
