Steel mill solid waste treatment method
The invention provides a steel mill solid waste treatment method, and relates to the technical field of waste treatment, and the method comprises the following steps: step 1, solid waste converter mud and ash are recovered in a centralized manner, and are respectively stored in a converter mud warehouse and an ash warehouse; 2, purchasing calcium quicklime powder and storing the calcium quicklime powder in a calcium oxide powder bin; 3, calcium quicklime powder is added into the converter mud according to the proportion, uniform stirring is conducted, primary digestion is conducted, and a primary digestion material is obtained; 4, mixing the converter mud subjected to primary digestion with ash; according to the method, calcium quicklime powder is added into converter mud for primary digestion, the converter mud is mixed with ash for secondary digestion, and then a binder and a heat generating agent are added, so that harmful elements in solid waste are neutralized by using the calcium quicklime powder, water is evaporated by using two-time digestion, water is evaporated by using the heat generating agent, and the strength is improved by using the binder; and the cold pressing block can be provided for a steelmaking converter and an ironmaking blast furnace to be used, and the quality of tapping and molten iron is guaranteed.
本发明提供了一种钢厂固体废料处理方法，涉及废料处理技术领域，包括以下步骤：步骤一：将固体废料转炉泥和灰集中回收，分别存放至转炉泥库以及以及灰仓；步骤二：采购钙质生石灰粉存放至氧化钙粉仓；步骤三：在转炉泥中按照比例添加钙质生石灰粉，搅拌均匀，进行一次消解，得到一次消解料；步骤四：将一次消解后的转炉泥与灰进行混合；本发明在转炉泥中添加钙质生石灰粉进行一次消解，与灰混合进行二次消解，再配入粘结剂和发热剂，以此，利用钙质生石灰粉中和固废中有害的元素，利用两次消解蒸发水份，利用发热剂反应蒸发水份，粘结剂反应提高强度，有利于提高冷压块的质量，可提供给炼钢转炉以及炼铁高炉进行使用，保证出铁和铁水质量。
