Waste heat utilization equipment and process for phosphogypsum calcining system
The invention relates to waste heat utilization equipment and technology for an ardealite calcining system, and belongs to the field of ardealite processing. The waste heat utilization equipment comprises a calcining furnace used for calcining ardealite and a drying furnace arranged on one side of the calcining furnace and used for drying sludge, and the drying furnace is communicated with a smoke exhaust pipe of the calcining furnace. The flue gas in the calcining furnace is guided into the drying furnace after being filtered, sludge is dewatered by utilizing heat of the flue gas, the sludge treatment time is shortened, the sludge treatment cost is reduced, production and development of enterprises are facilitated, heat in the flue gas is recycled, energy is saved, environment friendliness is achieved, and the energy-saving and environment-friendly sludge drying device conforms to the concept of sustainable development.
本申请涉及一种磷石膏煅烧系统余热利用设备及工艺，属于磷石膏加工领域，包括：用于煅烧磷石膏的煅烧炉以及设于煅烧炉一侧的用于干燥污泥的干燥炉，所述干燥炉与煅烧炉的排烟管相连通，本申请在使用时，将煅烧炉内的烟气过滤后导入干燥炉内，利用烟气的热量对污泥进行脱水处理，降低了污泥处理的时间与成本，有利于企业的生产与发展，对烟气中的热量进行了回收利用，节能环保，与可持续发展的理念相契合。
