Clean environment-friendly calcining furnace and method for indirectly treating dolomite
The invention provides a clean environment-friendly calcining furnace and method for indirectly treating dolomite. The calcining furnace comprises a gas trapping pipeline and a furnace body, wherein the furnace body comprises a blanking bin, a hearth and a discharging bin; a calcining area is formed in the hearth; the furnace body further comprises a heating device; a sealing plate for sealing a furnace opening of the hearth is arranged at the top of the hearth, and a communicating opening is formed in the sealing plate; a blanking port of the blanking bin communicates with the calcining area through the communicating opening; an exhaust cavity is formed between the outer wall of the blanking bin and the sealing plate through surrounding of a surrounding plate, and the exhaust cavity communicates with the calcining area through the communicating opening; and the gas trapping pipeline communicates with the exhaust cavity. According to the invention, the activity and purity of calcined dolomite can be improved, the impurity content of flue gas is reduced, high-purity CO2 gas is obtained, and the energy consumption required for calcining the dolomite can also be reduced.
本发明提供一种间接处理白云石的清洁环保煅烧炉及方法，所述煅烧炉包括气体捕集管道和炉体，所述炉体包括落料仓、炉膛和出料仓；所述炉膛的内部形成有的煅烧区，所述炉体还包括加热装置；所述炉膛的顶部设置有封闭所述炉膛的炉口的封板，且所述封板上开设有连通口；所述落料仓的落料口通过所述连通口与所述煅烧区连通；所述落料仓的外壁与所述封板之间通过围板围绕形成有排气腔室，所述排气腔室通过所述连通口与所述煅烧区连通；所述气体捕集管道与所述排气腔室连通。本发明可以提高煅白的活性和纯度，并降低烟气中的杂质含量，获得高纯的CO2气体，还能降低白云石煅烧所需的能耗。
