Mother liquor is stably held in 0 DEG C or so in saturation mother liquor, pre-cooled entrance freezing and crystallizing system afterwards, freezing and crystallizing system so that
Na2SO4With Na2SO4*10H2O crystalline salt forms are separated out, and can isolate Na2SO4Crystal salt.
At present, jacket heat-exchanger conventional in existing freezing and crystallizing system etc. by continuum micromeehanics due to being influenceed, crystal system
Temperature is difficult to keep stable, so as to influence Na2SO4Can not more it be completely separated；Further, since solution is supersaturated body after freezing
System, heat-transfer surface is very easy to crystallization/fouling in the heat-exchange system of relative quiescent, so as to influence heat exchange efficiency.
Utility model content
Technical problem to be solved in the utility model, which is to provide a kind of big flow simple in construction, stable, forces to follow
Ring good antiscale property freezing and crystallizing device.
To solve the technical scheme that above-mentioned technical problem is used：A kind of big flow forced circulation good antiscale property freezing and crystallizing dress
Put, including be sequentially connected the freezing and crystallizing tank for constituting circulation line, circulating pump and freezing heat exchanger, the freezing and crystallizing tank is with sinking
Drop room is connected, and the solution that freezing and crystallizing tank is included into finite concentration crystal salt is discharged into expansion chamber, in the freezing and crystallizing tank
Mother liquor pipeline is connected with pipeline between circulating pump constantly to provide pre- cold mother liquor, the freezing heat exchanger to circulation line
By carrying out cold and hot exchange with coolant circulating system.
Further, the coolant circulating system includes the refrigerant circulation that circulation loop is connected to form with freezing heat exchanger
Pump, freezing unit.
Further, hot mother liquor pipeline is connected with to circulation on the pipeline between the circulating pump and freezing heat exchanger
Pipeline provides hot mother liquor.
Beneficial effect：In this big flow forced circulation good antiscale property freezing and crystallizing device, carried out using big flow forced circulation
Freezing and crystallizing, the solution temperature difference before and after heat exchange is very small, and inflow temperature, changes in flow rate influence very on freezing and crystallizing system temperature
It is small so that solution temperature can be stablized in control temperature range in freezing and crystallizing tank, overcome traditional crystal system temperature to be difficult to protect
Keep steady fixed defect；It is additionally, since and is circulated using big flow, crystal collision is more in solution, and crystal grain is easy " growing up ", system pipes
Road, heat exchanger tube etc. have the high-velocity flow with crystal grain to wash away self purification, can be effectively prevented from crystal salt in surface attachment fouling.
Brief description of the drawings
The utility model is described further with reference to the accompanying drawings and examples；
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Reference picture 1, a kind of big flow forced circulation good antiscale property freezing and crystallizing device of the utility model, including it is sequentially connected structure
Into the freezing and crystallizing tank 1 of circulation line, circulating pump 2 and freezing heat exchanger 3, freezing and crystallizing tank 1 is connected with expansion chamber 4, will
The solution that freezing and crystallizing tank 1 includes finite concentration crystal salt is discharged into expansion chamber 4, the pipe between freezing and crystallizing tank 1 and circulating pump 2
Mother liquor pipeline 5 is connected with road constantly to provide pre- cold mother liquor to circulation line, freezing heat exchanger 3 passes through a coolant circulating system
Carry out cold and hot exchange.
In the present embodiment, solution and process mother liquor pipeline 5 in freezing and crystallizing tank 1 enter the solution of circulation line by following
Ring pump 2 is continuously pumped into freezing heat exchanger 3, and circulation solution carries out heat exchange, circulation solution temperature drop in freezing heat exchanger 3
Low so that saturation degree is also reduced, solution enters after freezing and crystallizing tank 1 after heat exchange, Na2SO4With Na2SO4*10H2O crystal salt shapes
Formula is separated out, and the solution of the crystal salt containing finite concentration is discharged into expansion chamber 4, and crystal is settled through Action of Gravity Field in expansion chamber 4, and heavy
Due to the influence that collided with each other between degree of supersaturation and crystal in drop, crystal further " growing up ", is deposited in the conical bottom of expansion chamber 4
Portion, crystal can isolate Na by discharge system outside gravity or pump2SO4*10H2O crystal salts, overflow of the supernatant in expansion chamber 4
Mouth is flowed outwardly, wherein, pre- cold mother liquor is constantly provided by mother liquor pipeline, and by circulating pump 2 to being freezed in freezing and crystallizing tank 1
Mother liquor carries out big flow circulation, and the solution temperature difference before and after heat exchange is very small, and inflow temperature, changes in flow rate are to freezing and crystallizing system
