Low-heating-value fuel gas double-chamber lime shaft kiln calcining system
The invention discloses a low-calorific-value fuel gas double-chamber lime shaft kiln calcining system which comprises a double-chamber lime shaft kiln, a main fuel gas spray gun, an auxiliary fuel gas spray gun, a flue gas dust remover, a rear induced draft fan and a dust remover chimney, and a gas inlet of a first-section calcining chamber in the double-chamber lime shaft kiln is connected with a pressurized air source; an air inlet of a lime cooling fan at the bottom of the double-chamber lime shaft kiln is connected with a lime cooling air pipeline, and an air outlet of the lime cooling fan is opposite to a second-section calcining chamber in the double-chamber lime shaft kiln; gas inlets of the main gas spray gun and the auxiliary gas spray gun are connected with a gas source, and gas nozzles are respectively opposite to the first-section calcining chamber and the second-section calcining chamber; and a shaft kiln chimney at the top of the double-chamber lime shaft kiln is connected with a dust remover chimney through a flue gas dust remover and a rear induced draft fan in sequence. According to the double-chamber lime shaft kiln, the calcining time is prolonged through segmented calcining, lime cooling air participates in combustion, the lime yield is increased, the problem that a traditional double-chamber lime shaft kiln cannot combust low-heating-value fuel gas is solved, and the operation cost of the double-chamber lime shaft kiln is greatly reduced.
本发明公开了一种低热值燃气双膛石灰竖窑煅烧系统，包括双膛石灰竖窑、主燃气喷枪、附燃气喷枪、烟气除尘器、后引风机和除尘器烟囱，所述双膛石灰竖窑内的一段煅烧室进气口与加压空气源连接；双膛石灰竖窑底部的石灰冷却风机的进气口与石灰冷却空气管道连接，出气口与双膛石灰竖窑内的二段煅烧室相对；所述主燃气喷枪和附燃气喷枪的进气口与燃气源连接，喷气口分别与一段煅烧室和二段煅烧室相对；双膛石灰竖窑顶部的竖窑烟囱依次经烟气除尘器、后引风机与除尘器烟囱连接。本发明通过分段煅烧延长煅烧时间和石灰冷却风参与燃烧的方式来提高石灰产量，解决了传统双膛石灰竖窑不能燃烧低热值燃气的问题，大大降低了双膛石灰竖窑的运行成本。
