Multi-Effect Evaporation Concentration Used Shell and Tube Heat Exchanger
Introduction
A shell and tube heat exchanger is a heat exchange device consists of a shell with a bundle of tubes inside it. According to design, shell and tube heat exchanger can be U-sharp tube heat exchanger and Straight tube heat exchanger.
Working principle
Two fluids of different starting temperatures, flow through the heat exchanger. One flows through the tubes (the tube side) and the other flows outside the tubes but inside the shell (the shell side). Heat is transferred from one fluid to the other through the tube walls.
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 |
