Lithium hydroxide single-effect evaporation crystallization system
Introduction
Single-effect evaporation is a kind of evaporation operation. It is
characteriazd in that the generated secondary steam is not used for
future evaporation of materials, but evaporation of a single
device. For single-effect evaporation, it is usually necessary to
calculate water evaporation, heating steaming consumption and heat
transfer area of evaporator after given prodution tasks and
determined operating conditions.
Lithium hydroxide is an inorganic substance, thechemical formul is
LiOH. It is white monoclinic fine crystal, spicy, strongly alkaline
and corrosive. The Ph of 1mol/L solution is about 14, and the PKB
is -0.04, It can absorb carbon dioxide and water in the air
,soluble in water, slightly soluble in ethanol and insoluble in
ether, The relative density is 1.45, the melting point is 471℃, and
it decomposes at 925℃.
Performance Comparison for Different Evaporator
| Item | Single effect evaporator | multi-effect evaporator | TVR evaporator | MVR evaporator |
| Energy consumption | energy consumption is much higher than others, 1ton water will
consume 1Ton steam in theory | comparatively energy conservation | Base on traditional multi-effect evaporator, one more effect added,
but higher pressure steam driven needed | The most energy saving technology for evaporator, but 10-40kwh
power consumption |
| Floor space | Small | large | large | small |
| Energy sources | steam & power, need steam pipe network and boiler | steam & power, need steam pipe network and boiler | steam & power, need steam pipe network and boiler, need high
pressure steam. | electricity, don't need pipe network, all the close-loop
circulation system |
| Automaticity | Semi automatic | Full automatic operation, continuous evaporation | Full automatic operation, continuous evaporation | Full automatic operation, continuous evaporation

Evaporator:
The liquid material inside the evaporator heated by steam for
evaporation. Choose different type evaporator according to
different liquid material features.
Separator(crystallizer):
use to separate vapor and liquid, according to different liquid
features choose different type separator(crystallizer), such as
normal separator, gravity separator, special design separator
(crystallizer ).
Vacuum system:
Use to keep the whole system vacuum degree, pump some air, fixed
gas, liquid entrainment of gas from the evaporator, so as to obtain
the whole system stable evaporation process.
Pump:
Use to transfer liquid and concentrated liquid. According to
different liquid features choose different pumps, such as
centrifugal pump, displacement pump,screw pump.
Control system:
MVR Evaporation system control center, by regular motor speed,
control valve,flow meter, temperature and pressure, to realize
automatic evaporation, cleaning, stop operations and so on.
Automatic alarm, automatic protection system is not damaged, keep
dynamic balance.
Cleaning system:
Different liquid after period of evaporator, there maybe scaling
phenomenon, general speaking, 99% of the scale can be removed by
adding chemical solvent, and can use CIP clean in situ or
disassemble to clean.
Scope of application:
Mechanical vapor compression(MVR) evaporator, suitable for milk,
glucose, organic acid, VC, xylose, pharmaceutical, chemical and
biological engineering, environmental engineering, waste recycling,
paper making, salt industry for low temperature concentration.
