Abstract
The invention provides a sodium sulfate TVR single-effect evaporation and crystallization system which comprises a mother liquor tank, a centrifuge, a preheater, a TVR compressor, a cooling crystallizer and a condenser, wherein the mother liquor tank, the preheater, the cooling crystallizer and the centrifuge are sequentially connected. The system has a simple structure and a small floor area, and mother liquor can be cyclically evaporated and crystallized, so that the utilization ratio is high.
Description
Technical field
The present invention relates to evaporative crystallization field, particularly relate to a kind of sodium sulfate TVR single effect evaporation crystal system.
Background technology
Thermodynamic steam recompression TVR, according to heat pump principle, steam from boiling-house is pressurized to elevated pressures, now, saturated vapor corresponding to it is higher relative to the vapor (steam) temperature of heating chamber, and steam then can be used again, and uses steam jet ejector i.e. to can reach requirement, being used the evaporative crystallization field in chemical products by relatively broad the most at present, the evaporative crystallization of sodium sulfate is exactly one of them.
Do not filter in there is problems in that centrifuge at present in sodium sulfate TVR single effect evaporation crystal system, mother solution is directly expelled directly out with crystallization product, mother solution is not taked recovery measure, and the mother solution through centrifuge can not be evaporated crystallization again, causes the waste of raw material.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is provided that a kind of simple in construction, floor space is little, and mother solution can circulating and evaporating crystallize, the sodium sulfate TVR single effect evaporation crystal system that utilization rate is high.The technical scheme following for realizing purpose of the present invention employing: a kind of sodium sulfate TVR single effect evaporation crystal system, including mother liquor tank, centrifuge, preheater, TVR compressor, cooler crystallizer and condenser, described mother liquor tank mother liquor outlet is connected with preheater import, preheater outlet is connected with cooler crystallizer mother solution entrance, described TVR compressor steam inlet connects raw jet chimney, TVR compressor steam (vapor) outlet connects cooler crystallizer steam inlet, described cooler crystallizer material outlet connects centrifuge, cooler crystallizer coolant outlet connects condenser, described centrifuge is connected with mother liquor tank.
As preferably, described centrifuge is perforated wall centrifuge.
As preferably, below described centrifuge, it is provided with filter cake.
As preferably, in described mother liquor tank, scribble corrosion-inhibiting coating.
Beneficial effects of the present invention: be provided with filter cake below centrifuge of the present invention, it is possible to efficiently separate crystalline solid and liquid, the liquid after separation enters mother liquor tank, is again evaporated crystallization, improves the utilization rate of raw material；Scribble corrosion-inhibiting coating in mother liquor tank, can prevent mother liquor tank from being corroded by raw material；Whole system simple in construction, floor space is little, and practical value is big.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
In figure: 1 be mother liquor tank, 2 be centrifuge, 3 be preheater, 4 be TVR compressor, 5 be cooler crystallizer, 6 be condenser, 7 be filter cake, 8 be raw jet chimney.
Detailed description of the invention
A kind of sodium sulfate TVR single effect evaporation crystal system, including mother liquor tank 1, centrifuge 2, preheater 3, TVR compressor 4, cooler crystallizer 5 and condenser 6, described mother liquor tank 1 mother liquor outlet is connected with preheater 3 import, preheater 3 outlet is connected with cooler crystallizer 5 mother solution entrance, described TVR compressor 4 steam inlet connects raw jet chimney 8, TVR compressor 4 steam (vapor) outlet connects cooler crystallizer 5 steam inlet, described cooler crystallizer 5 material outlet connects centrifuge 2, cooler crystallizer 5 coolant outlet connects condenser 6, and described centrifuge 2 is connected with mother liquor tank 1；Described centrifuge 2 is perforated wall centrifuge；, below described centrifuge 2, it is provided with filter cake 7；Corrosion-inhibiting coating is scribbled in described mother liquor tank 1.
The invention is not limited in the sodium sulfate TVR single effect evaporation crystal system involved by above-mentioned detailed description of the invention, those skilled in the art also can make multiple change accordingly, but any is equal to the present invention or similar change all should be contained within the scope of the claims.
