Low-nitrogen calcination ultralow-emission type environment-friendly lime kiln
The invention discloses a low-nitrogen calcination ultralow-emission environment-friendly lime kiln which is structurally characterized in that a flue gas outlet is connected with a flue gas mixer through a pipeline, the upper part of the flue gas mixer is connected with a humidifying and digesting feeder, and the lower part of the flue gas mixer is connected with a desulfurization flue; a bag-type dust collector is provided with three ends, the desulfurization flue is connected with the first end of the bag-type dust collector, the second end of the bag-type dust collector is connected with achimney through a smoke exhaust channel, and the third end of the bag-type dust collector is connected with an ash conveying bucket elevator through a pipeline; the ash conveying bucket elevator is connected with a lime powder bin; and the lower portion of the lime powder bin is connected with the humidifying and digesting feeder through a pipeline. The method has the advantages that the desulfurization flue is used for desulfurization, the desulfurization ash is separated through the bag-type dust collector, conveyed to the furnace top lime powder bin through theash conveying bucket elevatorand then fed into the desulfurization flue through the humidifying and digesting feeder, and thus high-rate cyclic utilization of the desulfurization ash is achieved. The desulfurization efficiency is improved, and the cost for independently arranging desulfurization tower equipment is saved.
本发明公开了一种低氮煅烧超低排放型环保石灰窑炉，其结构特征是：烟气出口通过管道和烟气混合器连接，烟气混合器上部连接加湿消化给料器，烟气混合器下部连接脱硫烟道；其中布袋除尘器设有三端，脱硫烟道和布袋除尘器第一端连接，布袋除尘器第二端通过排烟通道和烟囱连接；布袋除尘器第三端通过管道和输灰斗提机连接，输灰斗提机连接石灰粉料仓，石灰粉料仓下方通过管道连接加湿消化给料器。本发明的优点是：本发明通过利用脱硫烟道进行脱硫，脱硫灰通过布袋除尘器分离，经过斗提输灰机输送至炉顶石灰粉料仓再经过加湿消化给料器将脱硫灰加湿送入脱硫烟道，实现脱硫灰高倍率循环利用。提高了脱硫效率，节省了单独设置脱硫塔设备费用。
