Double-hearth kiln reconstructed from shaft kiln
The invention relates to a double-hearth kiln reconstructed from a shaft kiln. The double-hearth kiln comprises two kiln bodies, a feeding system, a waste gas exhaust system, a fuel feeding system, adischarging system and a control system. The upper part of each kiln body is provided with a feed port, and the lower part is provided with a discharge port. A kiln body calcining zone is provided with at least one fuel spray gun, the upper part of a preheating zone is provided with a smoke/combustion-supporting air port, and the lower part of a cooling zone is provided with a cooling air inlet. An external annular channel, an internal annular channel or a smoke channel opening is formed between the calcining zone and the cooling zone of each kiln body, the external annular channels, the internal annular channels or the smoke channel openings of the two kiln bodies are connected together through an external connecting channel, and smoke openings are formed between the external annular channels or the internal annular channels and the kiln chambers. By arranging the annular channels and the connecting channel, the kiln bodies of two beam type lime kilns or common shaft kilns are connected and transformed into the double-hearth kiln, energy conservation and environmental protection are achieved, the product quality is good, the double-hearth kiln is suitable for being rebuilt on thebasis of an existing lime kiln, and the economic benefits of enterprises are increased.
本发明涉及一种由竖窑改建的双膛窑，包括两个窑体、供料系统、废气排放系统、燃料供给系统、出料系统和控制系统。每个窑体的上部设有加料口，下部设有出料口。窑体煅烧带设有至少一根燃料喷枪，预热带上部设有烟气/助燃风口，冷却带下部设有冷却风入口。窑体的煅烧带与冷却带之间设有外置环形通道、内置环形通道或烟气道口，两个窑体的外置环形通道、内置环形通道或烟气道口通过外置连接通道连接在一起，外置环形通道或内置环形通道与窑膛之间设有烟气口。本发明通过设置环形通道和连接通道将两座梁式石灰窑或普通竖窑的窑体连接起来改造为双膛窑，节能环保、产品质量好，适于在现有石灰窑基础上改建，增加企业经济效益。

An external annular channel, an internal annular channel or a smoke channel opening is formed between the calcining zone and the cooling zone of each kiln body, the external annular channels, the internal annular channels or the smoke channel openings of the two kiln bodies are connected together through an external connecting channel, and smoke openings are formed between the external annular channels or the internal annular channels and the kiln chambers. By arranging the annular channels and the connecting channel, the kiln bodies of two beam type lime kilns or common shaft kilns are connected and transformed into the double-hearth kiln, energy conservation and environmental protection are achieved, the product quality is good, the double-hearth kiln is suitable for being rebuilt on thebasis of an existing lime kiln, and the economic benefits of enterprises are increased.
