Industrial waste heat steam recycling low-temperature calcining equipment
The invention provides industrial waste heat steam recycling low-temperature calcining equipment which comprises multiple stages of calcining cylinders and multiple stages of heat exchange cylinders, the calcining cylinders are contained in the heat exchange cylinders, the multiple stages of calcining cylinders are connected in series end to end, every two adjacent stages of heat exchange cylinders are connected end to end through a heat conduction pipe, and each stage of calcining cylinder is further connected with one end of a heat return pipe. The other end of the heat return pipe is connected with the cyclone separator and then connected with the first-stage calcining cylinder, and the head end of the last-stage heat exchange cylinder is further connected with steam source equipment through a steam supply pipe. By the adoption of the technical scheme, waste heat discharged by various industrial enterprises is used for conducting low-temperature calcination on the gypsum residues, in the calcination process, water vapor separated from the gypsum residues is mixed into steam in the heat exchange cylinder and then exchanges heat with the gypsum residues, the gypsum residues are calcined more sufficiently, the dehydration efficiency is improved, and the gypsum residues are recycled. The three phases of the gypsum powder tend to be stable through aging treatment, and the quality of the gypsum powder is improved.
本发明提供一种工业余热蒸汽循环利用低温煅烧设备，包括多级煅烧筒和多级换热筒，所述煅烧筒容纳于换热筒内，多级煅烧筒首尾串联在一起，相邻两级换热筒之间通过导热管首尾相连，每级煅烧筒还与回热管的一端连接，所述回热管的另一端接入旋风分离器后，再与第一级煅烧筒相连，最后一级换热筒首端还通过供汽管接入汽源设备。采用本发明的技术方案，利用各种工业企业排放的余热对石膏渣进行低温煅烧，煅烧过程中，使石膏渣中脱出的水蒸汽掺入换热筒的蒸汽中，再与石膏渣进行热交换，使石膏渣煅烧更充分，提升了脱水效率，还通过陈化处理使石膏粉三相趋于稳定，提高石膏粉品质。
