A biomass boiler flue gas denitrification equipment

Abstract

The invention discloses a biomass boiler flue gas denitrification device, which belongs to the field of flue gas treatment, comprising a denitrification cylinder, a smoke inlet pipe is fixedly installed on one side of the denitrification cylinder, a filter screen is fixedly installed on the side of the inner cavity of the denitrification cylinder close to the smoke inlet pipe, and also comprises: a mixing component, the mixing component comprises a circular frame rotatably installed in the inner cavity of the denitrification cylinder, a retarder is evenly fixedly installed on the circular frame, each group of the retarder is evenly opened with a circular opening, the outer side of each group of the circular opening is provided with an annular hole, and each group of the annular holes is opened in the adjacent retarder; the contact time between the flue gas and ammonia can be increased, and the mixing effect of the flue gas and ammonia can be improved, and the situation that the flue gas flow rate is too fast to be fully mixed and reacted with ammonia, thereby causing ammonia escape, can be avoided, and the safety of the reaction between the flue gas and ammonia can be effectively improved, and the effect of flue gas denitrification can be improved.
