摘要：NOVELTY - The utility model relates to denitration technology field, specifically relates to a kind of lance boom device. A spray gun device for SNCR denitration process, comprising a spraying tube located in the centre of the reducing agent, the reducing agent injection pipe outer layer of the annular spraying pipe, reducing agent injection pipe comprises a first channel, passage, the mixing passage, the tapered surface of the cone channel is provided with a tapered air inlet of the mixed channel. an annular spraying pipe is provided with a second passage, the second passage through air inlet communicated with the mixing channel. Because of adopting said technical scheme, this utility model through the secondary atomizing to obtain more fine uniform mist drops and improves the denitration efficiency.
