Method for producing building blocks by recycling industrial byproduct sulfuric acid and wet calcium slag
The invention discloses a method for resource production of building blocks by utilizing industrial byproduct sulfuric acid and wet calcium slag, and belongs to the technical field of resource production of building blocks by utilizing industrial byproducts, the method comprises the following steps: crushing and stirring wet calcium slag for 10-20 minutes; adding a byproduct sulfuric acid in 3-4 times; adding sieved plant ash residues, and then adding cement in a stirring state; the building block with the strength reaching 30 MPa can be produced by utilizing the byproduct plant ash slag of a biological power plant, the byproduct wet calcium slag of a paper mill, the industrial byproduct sulfuric acid and a small amount of cement, the byproduct sulfuric acid is treated, the plant ash and the wet calcium slag can be comprehensively utilized, and the method is a project for turning waste into wealth.
本发明公开了一种利用工业副产硫酸与湿钙渣资源化生产砌块的方法，属于工业副产资源化生产砌块技术领域，本发明包括以下步骤：湿钙渣破碎搅拌10‑20分钟；分3‑4次加入副产硫酸；加入过筛后草木灰渣，后在搅拌的状态下加入水泥；持续搅拌5‑10分钟后进行入模、压制工段，通过利用生物电厂副产的草木灰渣，造纸厂副产的湿钙渣，工业副产硫酸以及少量水泥，可以生产出强度达到30兆帕的砌块，既处理了副产硫酸又可以综合利用草木灰和湿钙渣，是一项变废为宝的工程。
