Abstract
(EN)
Provided is a condensation type desulfurization system, comprising: a tower body (100), comprising a liquid inlet installation port (101), a liquid outlet installation port (102), a flue gas inlet (103) and a flue gas outlet (104) communicating with an inner space of the tower body (100); a spray assembly (200), which is installed in the liquid inlet installation port (101), the inner end of which extends into the tower body (100), and the outer end of which is located outside of the tower body (100); a circulation pump (300), which comprises a liquid suction port (301) and a liquid discharge port (302), wherein the liquid suction port (301) is connected to the liquid outlet installation port (102) by means of a first circulation pipe (400), and the liquid discharge port (302) is connected to the outer end of the spray assembly (200) by means of a second circulation pipe (500); a heat exchanger (600), which is arranged facing forward on the middle section of the second circulation pipe (500); and condensation type demisters (700), which are arranged at the inner part of the tower body (100) and are located between the flue gas outlet (104) and the spray assembly (200). The condensation type desulfurization system may improve the desulfurization efficiency while reducing the moisture content of the flue gas.
