SCR LOW-TEMPERATURE DENITRATION DEVICE

The present disclosure provides a selective catalytic reduction (SCR) low-temperature denitration device, including a reactor shell which has a flue gas inlet and a flue gas outlet; an ammonia spraying grille for mounting a spraying head; a flue gas overflow channel is reserved between a catalyst storage tank and an inner side wall of the reactor shell; the flue gas overflow channel is communicated to the flue gas outlet; the catalyst storage tank includes an outer catalyst tank and an inner catalyst tank located in the outer catalyst tank; a material turning member is mounted in the inner catalyst tank; the material turning member has a fork sheet capable of rotating in a reciprocating manner; the fork sheet toggles catalyst particles in the inner catalyst tank; a reactor inner pipe is in the middle of the outer catalyst tank; the inner catalyst tank is clung to the reactor inner pipe.
