Production process for processing plastering gypsum by using semi-dry desulfurization ash
The invention provides a production process for processing plastering gypsum by using semi-dry desulfurization ash, and belongs to the technical field of solid waste treatment. The method comprises the following steps: feeding semi-dry desulfurization ash into a preheating kiln for preheating after passing through a raw material surge bin, a feeder and a metering screw conveyor, feeding the preheated desulfurization ash into an oxidation kiln through a chute, injecting a proper amount of oxygen, feeding the oxidized and modified desulfurization ash into a cooling kiln, feeding air into an oxidation rotary kiln in a countercurrent manner after absorbing the waste heat of a product, cooling the modified desulfurized fly ash, grinding and crushing by a ball mill and then conveying to a storage tank, metering the modified desulfurized fly ash, auxiliary materials and additives by a metering device according to a set mass ratio and then conveying to a mixing device, stirring the materials and mixing uniformly by a stirrer and then conveying to a finished product bin, and then packaging the finished product bin by a packaging system to produce a plastering gypsum product. The plastering gypsum product which can be directly utilized is produced by utilizing the semi-dry desulfurization ash, the method has relatively high market value and economic value, wastes are turned into wealth, and rich economic benefits are brought to enterprises.
本发明提供一种利用半干法脱硫灰加工抹灰石膏的生产工艺,属于固废治理技术领域。该方法首先将半干法脱硫灰经原料缓冲仓、给料机和计量螺旋输送机后送入预热窑进行预热,预热后的脱硫灰通过溜槽送入氧化窑,并注入适量氧气,氧化改性后的脱硫灰送入冷却窑,空气吸收产品余热后逆流送入氧化回转窑,改性脱硫灰冷却后经球磨机研磨粉碎后输送至储料罐,改性脱硫灰、辅料以及添加剂按照设定的质量比经计量装置计量后送入混料装置,搅拌机搅拌混合均匀后送入成品料仓,然后打包系统打包生产出抹灰石膏产品。本发明利用半干法脱硫灰生产出可直接利用的抹灰石膏产品,具有较高的市场价值和经济价值,变废为宝,为企业带来丰厚的经济收益。
