A method for purifying flue-gases deriving from a combustion plant involves first drawing flue-gases from the plant and through a liquid volume by suction and then pressing the gases through a liquid, whereafter the purified flue-gases are discharged to the surroundings. During their passage through the liquid, the flue-gases are divided into the smallest possible flow units so as to achieve the best contact with the liquid. The method is carried out with the aid of a flue-gas purifier (5) which includes a liquid container (6), preferably a water container, which is divided into chambers (18-24). One set of chambers (18-21) forms a suction department (A) and another set of chambers (22-24) forms a pressure department (B). Walls (12, 14, 16) which form partitions between the chambers force the flue-gases to pass alternately through liquid and above the surface of the liquid. A pump (26) sucks the flue-gases through the suction department (A) and presses these gases through the pressure department (B). The walls (12, 14, 16) are provided at least partially with slots through which the flue-gases are forced to pass, therewith dividing the flue-gases into several flows, and the pump outlet (28) opens into a nozzle which finely divides the gaz and which is submerged in the liquid. As seen in the direction followed by the flue-gases, the first chamber (18) in the suction department (A) is provided with an inlet (25) for flue-gases arriving from the combustion plant, while the last chamber in the pressure department (B) is provided with an outlet (29) for the purified flue-gases. |
