In view of this, the purpose of this utility model is to provide a kind of absorption tower of tape entry cascade, forms one the slurries cascade in the adsorption tower smoke porch, and former flue gas is tentatively removed to SO
2, improved the desulfuration efficiency on absorption tower.
The utility model discloses a kind of absorption tower of tape entry cascade, comprise absorption tower body and circulation slurry pump, described loop slurry pump discharge is connected with the slurries circulation pipe, described absorption tower body is provided with smoke inlet, be provided with the slurries shower in the body of described absorption tower, described slurries shower is connected with the slurries circulation pipe, body tower body smoke inlet top, described absorption tower is provided with slurries cascade case, between described slurries cascade case and absorption tower body, by overfall, be connected, described slurries cascade case is provided with the slurries input pipe that slurries are provided for slurries cascade case.
Further, described slurries circulation pipe end is provided with slurries circulation discharge pipe and is connected with the slurries input pipe.
Further, described slurries shower end is provided with slurries sprays discharge pipe and is connected with the slurries input pipe.
Further, described slurries cascade chamber interior wall is provided with the corrosion-inhibiting coating I.
Further, described overfall cross section lateral dimension is more than or equal to smoke inlet cross section lateral dimension.
Further, in the body of described absorption tower, overfall is provided with the overflow deflector.
Further, described overflow baffle surface is provided with the corrosion-inhibiting coating II.
The beneficial effects of the utility model are: the absorption tower of the utility model tape entry cascade, utilization is arranged on the slurries cascade case of body tower body smoke inlet top, absorption tower, make the adsorption tower smoke porch form the slurries cascade one, the former flue gas that enters absorption tower is tentatively removed to SO
2, then by the spray-absorption district on absorption tower to SO
2Carry out absorbing and removing.The utility model slurries circulation discharge pipe and slurries spray discharge pipe can keep flowing of slurries circulation pipe and the interior slurries of slurries shower, solved the problem that the slurries pipeline easily stops up, and for providing slurries, slurries cascade case make the adsorption tower smoke porch form the slurries cascade, former flue gas is carried out to pretreatment, improve the desulfuration efficiency on absorption tower, reduced use cost.
