Concentric annular double-chamber lime kiln
The invention relates to the technical field of limestone calcining equipment, in particular to a concentric annular double-hearth lime kiln which comprises an outer barrel, a middle barrel, an inner barrel, an outer calcining hearth, an inner calcining hearth, a connecting channel, a combustor, a smoke outlet, a limestone feeding port and a lime discharging port. The outer calcining hearth is an annular cavity formed by the outer barrel and the middle barrel, the inner barrel is located on the inner side of the middle barrel, the inner calcining hearth is an annular cavity formed by the middle barrel and the inner barrel, and the connecting channel penetrates through the middle barrel to communicate the outer calcining hearth with the inner calcining hearth. Through cooperative use of the external calcining hearth, the internal calcining hearth and the connecting channel, the smoke flowing smoothness and the uniformity of the temperature in the kiln can be improved, and the heat dissipating capacity of the surface of the lime kiln is reduced, so that the lime quality and the heat efficiency of the lime kiln are improved.
本发明涉及石灰石煅烧设备技术领域，尤其为一种同心环形双膛石灰窑，包括外筒体、中间筒体、内筒体、外煅烧炉膛、内煅烧炉膛、连接通道、燃烧器、烟气出口、石灰石进料口、石灰出料口，所述外筒体位于中间筒体的外侧，所述外煅烧炉膛为外筒体与中间筒体形成的环形腔体，所述内筒体位于中间筒体的内侧，所述内煅烧炉膛为中间筒体与内筒体形成的环形腔体，所述连接通道贯穿中间筒体，将外煅烧炉膛与内煅烧炉膛连通。本发明通过对外煅烧炉膛、内煅烧炉膛和连接通道的配合使用，能够提高烟气流动的畅通性与窑内温度的均匀性，并减小石灰窑表面的散热量，从而提高石灰品质与石灰窑热效率。
