Title:
Concentration device
Document Type and Number:
Japanese Patent JP6280170
Kind Code:
B2
Abstract:
To provide a concentrator improved in heat utilization efficiency for concertation. A concentrator comprises: an absorber for heating concentration object fluid flowing through a concentration object fluid channel with the heat of absorption generated when an absorbent Sa absorbs coolant steam Ve; an evaporator for creating the coolant steam Ve by heating coolant liquid Vf with the heat held by coolant heating fluid he flowing through a coolant heating fluid channel; a regenerator for increasing the concentration of absorbent Sw by withdrawing coolant steam Vg after heating the absorbent Sw introduced from the absorber; a condenser for creating the coolant liquid Vf by cooling and condensing the coolant steam Vg introduced from the regenerator; a gas-liquid separator for separating the concentration object fluid Wm heated by the absorber into departure vapor Wv and concentrated liquid Wc; and heating parts 69 and 79 for heating heated fluids Vf and Sw with the heat of the introduced departure vapor Wv, in which the internal pressure of the absorber 10 is higher than that of the regenerator.
