Description
技术领域 technical field
本实用新型涉及铜冶炼厂的废液处理领域, 具体而言，涉及一种铜冶炼厂生产过程中用于酸性废液处理的石灰石乳制备系统。 The utility model relates to the field of waste liquid treatment of copper smelters, in particular to a limestone milk preparation system used for acid waste liquid treatment in the production process of copper smelters.
背景技术 Background technique
铜冶炼厂生产过程中,铜精矿采用火法熔炼，精矿中的硫等有价元素往往采取烟气制酸方法回收，而在制酸和其他辅助生产过程中会有不少酸性废液产生。 这些酸性废液需一定的碱性中和剂进行酸碱中和,使中和后液达标排放，满足环境保护要求。目前生产实践中，一般采用的处理酸性废液的中和用常用材料有石灰，石灰石等。石灰溶于水作为中和碱液虽有简单方便的优点，但石灰不便于贮存运输，现场制作石灰液也较烦琐。相比较而言，石灰石则具有价廉易得，便于贮存运输的优点。石灰石原料一般为较大块状，而直接使用石灰石原料来中和酸性废液，反应效率较低。因此有必要采用一种高效快速的石灰石乳液制备设备来制备出石灰石乳液进行酸碱中和，使酸性废液在与石灰石乳液中和后满足环保排放的要求。 In the production process of copper smelters, copper concentrates are smelted by fire, and valuable elements such as sulfur in the concentrates are often recovered by flue gas acid production, and there will be a lot of acid waste liquid in the acid production and other auxiliary production processes produce. These acidic waste liquids need a certain amount of alkaline neutralizer for acid-base neutralization, so that the neutralized liquid can be discharged up to the standard and meet the requirements of environmental protection. In the current production practice, lime, limestone and the like are commonly used for neutralization of acidic waste liquid. Lime dissolved in water as neutralizing lye has the advantages of simplicity and convenience, but lime is not convenient for storage and transportation, and making lime solution on site is also more cumbersome. In comparison, limestone has the advantages of being cheap, easy to obtain, and convenient for storage and transportation. Limestone raw materials are generally large blocks, and the direct use of limestone raw materials to neutralize acidic waste liquid has low reaction efficiency. Therefore, it is necessary to use an efficient and fast limestone emulsion preparation equipment to prepare limestone emulsion for acid-base neutralization, so that the acid waste liquid can meet the requirements of environmental protection discharge after being neutralized with limestone emulsion.
