Desulfurized gypsum calcination production process
The invention provides a flue gas desulfurization gypsum calcination production process, and relates to the field of flue gas desulfurization gypsum production. The flue gas desulfurization gypsum calcination production process comprises the following specific steps: step 1, homogenizing raw materials to enable the quality of the raw materials to be uniform; 2, adding desulfurized gypsum into a dryer, adding the desulfurized gypsum into a roller through a feeding pipe, and connecting an air inlet with a hot air box to blow in hot air; 3, a motor is started to drive a roller to rotate, the desulfurized gypsum is dried, internal free water is removed, and the temperature is 65-75 DEG C; step 4, discharging the dried desulfurized gypsum through a first discharge port and a second discharge port; 5, conveying the desulfurized gypsum into a calcining rotary kiln, and removing internal crystal water at the temperature of 170-190 DEG C for 3-6 minutes; and 6, calcining to obtain the building gypsum powder. And through the use of the vibrating mechanism and the lifting plate, materials are dried more thoroughly in the roller, dust attached to the roller wall is knocked down, and the drying effect is prevented from being affected.
本发明提供一种脱硫石膏煅烧生产工艺，涉及脱硫石膏生产领域。该脱硫石膏煅烧生产工艺，包括以下具体步骤：步骤一：将原料均化处理，使其质量均匀；步骤二：将脱硫石膏加入烘干机内，通过进料管加入滚筒内，并将进风口与热风箱相连，使热风吹入；步骤三：启动电机带动滚筒旋转，对脱硫石膏进行烘干，去除内部游离水，温度为65‑75℃；步骤四：烘干完成的脱硫石膏通过第一出料口和第二出料口排出；步骤五：将脱硫石膏输送入煅烧回转窑中，去除内部结晶水，温度为170‑190℃，时间为3‑6mi n；步骤六：完成煅烧后即可得到建筑石膏粉。通过振动机构和扬料板的使用，使得物料在滚筒内干燥更加彻底，同时将附着在筒壁上的粉尘敲下，避免影响烘干效果。
