The utility model discloses a novel SCR denitration device, including SCR denitration reactor, set up at the deNOx systems entry flue at SCR denitration reactor top and set up the deNOx systems exhaust pass of SCR denitration reactor bottom, from the top down sets gradually guide vanes, flow straightening grid and SCR denitration catalyst layer in the SCR denitration reactor, SCR denitration catalyst layer below sets up ammonia desorption catalyst layer, deNOx systems entry flue includes horizontal gas pass and vertical gas pass, set up the pre -dusting device in the deNOx systems entry flue, the pre -dusting device is including fixing at the slope dust removal board on horizontal gas pass upper portion, fixing at the level dust removal board of vertical gas pass side and set up the dust arrester in the vertical gas pass bottom. This denitrification facility simple structure, the deamination is effectual, and most coarse grain smoke and dust in the flue gas can be eliminated to the pre -dusting device moreover, and the soot blower deashing is effectual, catalyst long service life. |
