The invention relates to an integrative adsorptive dust collection device. A box body is divided into one or a plurality of branch chambers, a plurality of filter bags and a barrel type adsorber are vertically installed in each branch chamber, the barrel type adsorbers are provided with pipe barrels, and adsorbents are arranged in the pipe barrels. Airflow with dust and gaseous pollutants enters the barrel type adsorbers after the dust collection of the airflow is carried out by the filter bags, and various gaseous pollutants are adsorbed by the adsorbents. According to the integrative adsorptive dust collection device, the collection of the dust and the desorption of the gaseous pollutants are integrated together, only the area of a bag type dust collector is occupied, and the integrative adsorptive dust collection device can be reconstructed on the basis of an original bag type dust collector, so that the original bag type dust collector has the function of removing the gaseous pollutants; and the device has large airflow treating quantity, small influence caused by the change of the fume quantity, no secondary pollution and no water consumption. The adsorbents can be regenerated for many times and are repeatedly utilized. According to the integrative adsorptive dust collection device, gaseous pollutants discharged by the combustion equipment of particulate matters, SO2, NOx, Hg and the like and toxic and harmful gaseous organic pollutants discharged by industries can be simultaneously and effectively removed.
