TVC-MED HAVING NON-CONDENSIBLE GAS VENTING SYSTEM

摘要

The present invention relates to a non-condensable gas venting structure of TVC-MED and more particularly, to a non-condensable gas venting structure of TVC-MED which can address a phenomenon that a heat transfer efficiency declines as a non-condensable gas is recycled by a thermo-vapor compressor (TVC) and accumulated inside an evaporator. According to one embodiment of the present invention, the non-condensable gas venting structure of TVC-MED comprises: an inlet pipe to which seawater is introduced; a heat exchanger for generating steam by heating the seawater; an effect for having a tube through which the steam flows and for forming freshwater and brine as the seawater is injected to the tube and some of the seawater is evaporated and concentrated; and a multi effect distillation (MED) apparatus having a brine discharge tube for discharging the brine wherein a non-condensable gas bypass pipe is provided for connecting a previous effect of an effect connected to TVC to a following effect of an effect connected to TVC or for being directly connected to a final condenser.
