TVR Evaporator
Working Principle
Energy savings are achieved by using a Thermal Vapor Recompressor (TVR) to recover part of the evaporated steam and supply it as a portion of the heating steam to the evaporator.
The TVR uses the suction force generated by a high-pressure steam flow to draw in water vapor and compress it into high-temperature steam. In other words, the TVR, driven by high-pressure steam, recovers part of the evaporated vapor as heating steam, thereby reducing the steam energy consumption of the concentration and evaporation equipment.
Special Features
The steam-saving effect of a TVR is equivalent to adding one more evaporator to a conventional multi-effect concentration and evaporation system. However, compared to adding an actual evaporator, using a TVR can significantly reduce equipment investment costs.
The design and performance of a TVR require precise engineering and reliable technical assurance.
Generally, as the internal steam nozzle of a TVR wears over time, its performance gradually declines, leading to increased steam consumption. Additionally, noise control technology is necessary for TVR operation.
