Chlorine-containing flue gas absorption and purification device

Abstract: The utility model discloses a chlorine-containing flue gas absorption and purification device. The chlorine-containing flue gas absorption and purification device comprises five spray towers, namely, a first level spray tower, a second level spray tower, a third level spray tower, a fourth level spray tower and a fifth level spray tower, wherein a raw material circulating groove is correspondingly arranged below each spray tower. Chlorine-containing flue gas sequentially passes through the five spray towers and generates a contact reaction with copper anode slurry in the spray towers, and the flue gas with chlorine removed is exhausted into the atmosphere; and the copper anode slurry enters the raw material circulating grooves corresponding to the spray towers by means of gravity after being sprayed from the spray towers and enters the spray towers through power devices in the raw material circulating grooves so as to circulate the copper anode slurry.
