The invention relates to a beam kiln for producing lime. The beam kiln comprises a kiln body, an air supply system, a waste gas emission system and a control system. A feeding port is formed in the upper portion of the kiln body, and a discharging port is formed in the lower portion of the kiln body. A preheating zone in the kiln body is provided with an upper suction and denitration beam, a cooling zone is provided with a lower suction beam, a calcining zone is provided with a combustion beam, an upper auxiliary beam, a middle auxiliary beam and a lower auxiliary beam, and the combustion beam, the upper auxiliary beam, the middle auxiliary beam and the lower auxiliary beam are sequentially installed from top to bottom. An injection air gun is arranged at one end of the combustion beam andinserted into the box body of the combustion beam. One ends of the upper auxiliary beam and the middle auxiliary beam are provided with high-pressure air inlets, the other ends are provided with high-pressure air outlets, the high-pressure air inlets are connected with the air supply system, and the high-pressure air outlets are connected to inlets of the injection air gun. According to the beamtype kiln for producing lime, the combustion beam and the auxiliary beam are arranged in the kiln body, the upper air suction beam and the lower air suction beam are arranged in a matched mode, the air inlet amount of the beam type lime shaft kiln can be reduced, and waste gas emission is reduced.
本发明涉及一种生产石灰的梁式窑，包括窑体、供风系统、废气排放系统和控制系统。窑体的上部设有进料口,窑体的下部设有出料口。窑体内的预热带设有上抽吸和脱硝梁，冷却带设有下抽吸梁，煅烧带设有燃烧梁、上辅助梁、中辅助梁和下辅助梁，燃烧梁、上辅助梁、中辅助梁和下辅助梁由上至下依次安装。燃烧梁的一端设有引射风枪，引射风枪插入燃烧梁的箱体。上辅助梁和中辅助梁的一端设有高压风入口，另一端设有高压风出口，高压风入口与供风系统连接，高压风出口连接到引射风枪入口。本发明提供的生产石灰的梁式窑通过在窑体内设置燃烧梁和辅助梁结构，配合设置上下吸气梁，能够减少梁式石灰竖窑的进风量，减少废气的排放。
