1.背景简介中盐安徽红四方股份有限公司合成氨生产气头采用的是水煤浆气化技术,需要制备水煤浆,即将原料煤、水、添加剂等按照一定比例加入棒磨机,制成合适浓度的水煤浆,经加压送到气化炉与纯氧燃烧生产合成气。公司氯碱系列产品之一保险粉,由于工艺条件的限制,在生产过程中产生部分生成水及原辅材料带来的工艺水,因此在合格的保险粉产出之际,整个保险粉生产装置也产生出大量的废液。这部分废液经过蒸发过滤处理,残渣作为固废填埋,蒸发冷凝液作
1. Background brief Salt in Anhui Red Sifang Co., Ltd. Ammonia gas head gasification is the use of coal-water slurry gasification technology, the need for the preparation of coal-water slurry, about to raw coal, water, additives, such as adding a certain percentage according to the rod mill, made of The appropriate concentration of coal-water slurry, pressurized to the gasifier and pure oxygen combustion synthesis gas production. One of the company’s chlor-alkali series of insurance powder, as the process conditions, in the production process to produce part of the water generated by raw and auxiliary materials and process water, so when the output of qualified insurance powder, the entire insurance powder production equipment Produce a lot of waste. This part of the waste after evaporation filtration, the residue as solid waste landfill evaporation condensate for
