  • The TVR evaporator, or Thermal Vapour Recompression Evaporator, is an efficient evaporation equipment that utilizes the siphon principle of ejector heat pumps to recover part of the secondary steam. According to theoretical calculations and practical experience, an ejector heat pump can entrain 0.3 kg of secondary steam with 1 kg of high-pressure steam. Adding an ejector heat pump to a plate evaporation system is equivalent to adding an additional effect evaporator, but the investment cost is far lower than that of adding an actual effect evaporator. By utilizing the principle of thermal recompression, low-temperature steam is compressed, heated, and reused, thereby achieving energy recycling.

    Tube TVR evaporator Process Description

    Preheating

    Before entering the evaporator, the feed liquid typically passes through a preheater to be preheated using another heat source, thereby improving evaporation efficiency.

    Evaporation

    The preheated feed liquid enters the evaporator and is heated to the boiling point under appropriate pressure, forming water vapor and concentrated liquid.

    Steam Compression

    The generated secondary steam is sent to a steam ejector, where it mixes with high-pressure, high-temperature steam, resulting in an increase in temperature and pressure.

    Heat Reutilization

    The mixed steam enters the heater, providing a heat source for the evaporator and realizing energy recycling.

    Condensation and Discharge

    The heated steam condenses into water in the condenser, part of which can be recycled, while the rest is discharged as wastewater.

    The TVR evaporator demonstrates significant energy-saving effects by recovering and utilizing the waste heat of secondary steam, reducing energy consumption. It is suitable for various industries, features easy operation with an automated control system, is stable and reliable, reduces manual intervention, and is easy to clean.
