During specific works, manganese sulfate stock solution to be evaporated for low concentration is first delivered to one-level preheater 1,
After the steam condensate (SC) heat exchange that manganese sulfate stock solution in one-level preheater 1 and described draining pump 4 are brought, institute
The temperature stating manganese sulfate stock solution raises, and is entering the waste gas heat exchange that described off-gas condenser 2 produces with system,
Stock solution temperature continues to raise, and the water vapor condensation in waste gas so that gas-liquid separation, gas discharging, stock solution is entered
Enter forced circulation pump 7 entrance point pipeline, through the effect of forced circulation pump 7 so that it is from the lower end of heater 6
Import enters, and leaves from upper end outlet, enters back into separator 8, eventually re-enters forced circulation pump 7
Import.
When starting shooting for the first time, need the steam side to heater 6 to be passed through fresh steam, make manganese sulfate stock solution heat up,
After manganese sulfate stock solution is seethed with excitement, stop fresh steam supply, open vapour compression machine 9 so that it is compression boiling is produced
Raw indirect steam, the indirect steam after compression enters the steam side of heater 6, provides thermal source for it, makes
Obtaining the stock solution in vaporizer can be persistently by thermal evaporation, and after pervaporation, original liquid concentration rises to about 54%,
Now the salt receiver 15 bottom separator 8 can accumulate a small amount of manganese sulfate monohydrate Crystal suspensions, these
Suspension is sent to the entrance point pipeline of crystallizer circulating pump 12 by suspension discharging pump 10.
The left and right of suspension crystallized device circulating pump 12 so that it is enter from crystallizer heater 11 bottom feed mouth
Enter, leave from top discharge mouth, enter back into the downspout in the middle of continuous crystalizer 13, directly rush at continuously
Bottom crystallizer 13, then reversely rising；Eventually re-enter the import of crystallizer circulating pump 12, by
In being configured with crystallizer circulating pump 12 so that suspension is imitated through the heat transfer of crystallizer heater 11 heat exchange
Rate is greatly enhanced, and improves production intensity.
When suspension enters crystallizer heater 11, the synthesis of described crystallizer heater 11 needs to be passed through fresh
Steam is its heating, its temperature is promoted to about 115 DEG C, utilizes manganese sulfate monohydrate temperature to raise, and dissolves
The feature that degree declines so that it is separate out a large amount of manganese sulfate monohydrate crystalline solid.
Final substantial amounts of manganese sulfate monohydrate crystalline solid is discharged by crystallizer discharging pump 14, goes to subsequent technique.
Existing for evaporative concentration stage of saline triple effect evaporator is replaced with MVR (mechanical vapor by this device
Recompression) mechanical steam is at Compression Evaporation device；This is a kind of can to reclaim indirect steam completely
Vaporising device, it is rotated by electrical energy drive compressor, compresses indirect steam, improves the temperature of indirect steam
And pressure, the indirect steam after compression provides thermal source for system again, and maintaining evaporation continuously needs
Energy be only to improve the electric energy required for indirect steam heat enthalpy value；For triple effect evaporator,
The energy consumption of MVR evaporator evaporation water per ton is about its 40-50%, and the most energy-conservation effect is the most obvious.
It addition, this device adds fixed gas condenser system, described fixed gas condenser system includes waste gas condensation
Device 2 and corresponding piping facility；The fixed gas that MVR vaporizer and continuous crystalizer produce can be received by it
Collection gets up, and reclaims its heat, saves energy consumption, condenses away steam, drop that fixed gas carries simultaneously, make
Harmful drop separates with the air in fixed gas, it is to avoid existing production technology causes house exhaust arbitrarily to discharge
The injury brought to workman.
Finally, existing crystallization kettle evaporative crystallization is modified to continuous evaporating crystallizer, described continuous steaming by this device
Send out crystallizer and include crystallizer heater 11, crystallizer circulating pump 12, continuous crystalizer 13 and crystallizer
Discharging pump 14；This crystallizer, through particular design, can produce manganese sulfate monohydrate crystal continuously, only needs
Wanting a continuous crystalizer, it is possible to realize the production capacity of existing 5 crystallization kettles of technique, the equipment that reduces takes up an area
Area, it is to avoid existing technique Batch Process efficiency is low, personnel depaly is more, producers' easily occupation is sudden and violent
The popularization of the shortcoming of dew, beneficially market and application.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all at this
Within bright spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in this
Within bright protection domain.
