Abstract
Provided are a separation tower and method for treating condensed water. In order to overcome the defects that an apparatus has high investment and energy consumption and requires high safety due to the need to use an organic phase as an extractant, the present disclosure provides a separation tower for treating condensed water. The water separation tower includes a tower body. Evaporation units for purifying the condensed water are disposed in the tower body. A final-effect condensation unit is disposed below the evaporation units and connected with a vacuum pump. The present disclosure has the following beneficial effects: 1) the gravity is used, thereby omitting an intermediate pump and saving the power cost and a matching control system; 2) a pressure difference between every two effect evaporation units is designed, and heat energy provided by a first-effect evaporation unit is continuously evaporated to achieve separation, so that subsequent effect evaporation units do not require external heat sources; and 3) the degree of integration is high, the sealing property is good, a vacuum is easy to realize, a subsequent vacuum system is small, the energy consumption is low, a devi…
