The invention relates to a double-chamber lime kiln denitration system. The double-chamber lime kiln denitration system comprises a double-chamber kiln and a denitration system, the double-chamber kiln is provided with two kiln bodies, and a preheating zone, a calcining zone and a cooling zone are arranged in each kiln body. Annular channels are arranged on the lower portions of the two kiln bodies, and a smoke channel is arranged between the annular channels of the kiln bodies on the two sides. The denitration system is provided with denitration spray guns. The denitration spray guns are installed on the upper portions or the side walls of the annular channels, and 2-10 denitration spray guns are arranged on the kiln body on each side. Each annular channel is provided with fire poking holes, and the denitration spray guns are installed at the fire poking holes. The denitration nozzles are additionally arranged in the annular channels of the double-chamber lime kiln, and the denitration agent is sprayed into the annular channels for denitration, so that the denitration effect is improved, nitrogen oxides in flue gas in the limestone calcining process are effectively removed, and the nitrogen oxide content of the flue gas discharged by the double-chamber lime kiln is reduced.
本发明涉及一种双膛石灰窑脱硝系统，包括双膛窑和脱硝系统，双膛窑设有两个窑体，窑体内设有预热带、煅烧带和冷却带。两个窑体的下部设有环形通道，两侧窑体环形通道之间设有烟气通道。脱硝系统设有脱硝喷枪。脱硝喷枪安装在环形通道的上部或侧壁，每侧窑体设有2‑10个脱硝喷枪。环形通道设有拨火孔，脱硝喷枪安装在拨火孔处。本发明通过在双膛石灰窑的环形通道加设脱硝喷嘴，利用脱硝剂喷入环形通道脱硝，提高了脱硝效果，有效脱除了石灰石煅烧过程中烟气的氮氧化合物，降低了双膛石灰窑排放烟气的氮氧化物含量。
