Description
Technical field
The utility model is related to a kind of enrichment facility of sulfate process titanium dioxide titanium liquid.
Background technology
The process product titanyl sulfate solution of sulfuric acid method titanium pigment needs to increase by low-temperature evaporation in process of production
Concentration, to meet technological requirement, at present, titanium powder industry in China is substantially or rising diaphragm type vacuum evaporation using traditional single-action sets
For being concentrated, this equipment averagely often produces 1 ton of titanium dioxide product needed and consumes 2.0-3.0 ton 0.3Mpa saturated vapor, produces
Relatively costly.The major defect of prior art is as follows：
1st, steam energy consumes greatly.Due to adopting single effect evaporation, 1 ton of water of evaporation needs to consume 1.25-1.7 ton steam；
2nd, heat dissipation is many.Due to adopting single effect evaporation, the quantity of steam that evaporimeter is discharged is equal to evaporation capacity, and required condensation sets
Standby and cooling device is big；
3rd, traditional handicraft rises film or the easy fouling and clogging of falling film type heater tube side, and use and maintenance maintenance cost is high；
4th, directly heat the diluter titanyl sulfate salting liquid of concentration with high-temperature steam and easily cause saline hydrolysis generation.
Utility model content
The purpose of this utility model is to provide a kind of enrichment facility of sulfate process titanium dioxide titanium liquid, saves steaming effect substantially,
Heat dissipation substantially reduces, and using multiple-effect evaporation, condensing plant and cooling device scale and energy consumption are low.Reduce tube side because of local mistake
The hydrolysate that heat occurs blocks the problem of tube side；Using the relatively low indirect steam lifting titanyl sulfate concentration of salt solution of temperature,
So that the concentration when subsequently giving birth to steam heating for the titanyl sulfate salting liquid is improved, significantly reduce the generation of saline hydrolysis.
A kind of enrichment facility of sulfate process titanium dioxide titanium liquid described in the utility model, including 1st effective evaporator, an effect evaporation
Device connects two effect heat exchangers by pipeline, and two effect heat exchangers pass through the first pipeline and connect material liquid import；1st effective evaporator bottom

The raw steam inlet of setting on one effect heat exchanger.
Form circulation so that titanium liquid fully absorbs steam heat between 2nd effect evaporator of the present utility model and two effect heat exchangers
Amount, greatly improves energy-saving effect.
Two effect heat exchangers of the present utility model, the tube side phase with 2nd effect evaporator and an effect heat exchanger and 1st effective evaporator
Logical；One effect heat exchanger tube pass is communicated with two effect heat exchanger shell pass through 1st effective evaporator, and two effect heat exchanger tube pass are through 2nd effect evaporator
Communicate with three-effect heat exchanger shell side.
The indirect steam that before concentration, titanium liquid produces in an effect evaporating concentration process, vacuum is pulled into 2nd effect evaporator,
Double flash evaporation concentration process, three steam of generation are drawn to triple effect heating system by vacuum again.
Comprise the concrete steps that：After before concentration, titanium liquid is heated by three-effect heat exchanger, enter two effect heat exchangers titanium liquid is entered again
Row heating, is evaporated subsequently into 2nd effect evaporator, using circulation after partly the titanium liquid after evaporation is mixed with titanium liquid before concentration
Effect returns two effect heat exchangers and is circulated heating, and the titanium hydrorrhea after another part evaporation flow to an effect heat exchanger via raw steam
Enter 1st effective evaporator after intensification to be evaporated, the concentration titanium liquid after evaporation delivers to subsequent processing.
The indirect steam that 1st effective evaporator produces, is used as thermal source return two effect heat exchangers by vacuum traction and is heated,
Titanium liquid after heating enters to 2nd effect evaporator and is evaporated, and three evaporating time steam is delivered to three-effect heat exchanger and heated.
The utility model is primarily adapted for use in black titanium liquid.
Compared with prior art, the utility model has the advantages that：
1st, save steaming effect substantially, one ton of water of evaporation about uses 0.7-0.8 ton steam；
2nd, heat dissipation substantially reduces.Due to adopting multiple-effect evaporation, the quantity of steam that evaporimeter is discharged just corresponds to evaporation capacity
45-50%, required condensing plant and cooling device scale and energy consumption reduce；
3rd, increasing flow velocity using tube side circulation technology, to greatly reduce the hydrolysate that tube side occurs because of hot-spot stifled
The problem of plug tube side；
4th, adopt the indirect steam lifting titanyl sulfate concentration of salt solution that temperature is relatively low, be allowed to when subsequently giving birth to steam heating
Concentration improve, significantly reduce the generation of saline hydrolysis.
