Twin-jet wet-method desulphurization dust collector

The utility model relates to a twin-jet wet-method desulphurization dust collector. The twin-jet wet-method desulphurization dust collector comprises a secondary spraying pipe (13) which is installed on a top plate of a dust collector barrel (14), wherein the secondary spraying pipe (13) and a primary spraying pipe (3) are respectively distributed on two sides of an exhausting opening (1), the upper end of the secondary spraying pipe (13) is connected with a spraying liquid pipe, and the lower end of the secondary spraying pipe (13) is arranged in the dust collector barrel (14). By additionally arranging the secondary spraying pipe and arranging the secondary spraying pipe on a part with a given height, uniformity in distribution of a desulphurization liquid can be favored, the desulphurization liquid can be supplemented, the staying reaction time of SO2 in the dust collector can be prolonged, water content of the flue gas can be prevented from being out of limits, the desulphurization effect is good, and the
