MVR evaporative crystallization for NaCl and lithium chloride
Principle
MVR forced circulation crystallization system comprises a vapor compressor,a heat exchanger,a crystallizer,and a forced circulation pump.The system makes use of the externally imposed power(circulating pump)to pump the solution and raw materials in the circulation pipe to the heating chamber.In doing so,the circulation rate is then greatly improved.After the circulating fluid passes through the heat exchanger for heating,it relieves pressure appropriately in the separator and becomes partially evaporated,cooling the liquid to the boiling temperature corresponding to the pressure.The secondary vapor separated from the separator and treated by the compressor is then handled to the heat exchanger for shell side heat exchange,maintaining the evaporating temperature of materials.When the system comes to the stable,no supplement of additional fresh steam is required.
Advantage
1, Longer operating cycle:The boiling /evaporating process happens in the separator rather than on the heating surface so that the scaling phenomenon due to crusting and precipitation inside tubes is then minimized.
2, Optimized heat transfer surface:the flow rate inside tubes is determined by the circulating pump.
3, Suitable for easy -to-encrust and high viscosity liquids,acting as a concentrator in the multi-effect evaporation plant.
4, The forced circulation evaporator is operable as a crystallizing evaporator for salt solutions.
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 |
