Slurry slag refining technique and mixed products with cement and thereof

Abstract

The invention relates to a slag refining process, which comprises the following steps: the slag is collected; necessary building materials and renewable materials are picked up from the slag; the building materials are picked up in a closed boiler by combustion, and the combustion gas is used for power generation; the combustion products are crushed to form particles or powder; and, the particles or powder formed by crushing are mixed with cement according to a preset blending ratio, and the mixture is made into be necessary products. The invention also provides a mixing product of cement and the slag refined by the process. The slag refining process has the advantages of fully utilizing the waste slag, resolving the problem of the slag ever increasing during the municipal construction, changing the waste slag into useful products, and obtaining the environment friendly type cement product by the reutilization; moreover, because the combustion gas is used for power generation in the slag refining process, the combustion gas is not emitted in the atmosphere, thereby fully utilizing the new energy generated by the slag refining process, saving quantities of state-owned lands, saving a great amount of social management expenditure for governments, providing the higher potential return of investment for enterprises, and greatly pushing the environmental protection construction and the sustainable development of cities forward.

Description

technical field [0001] The present invention relates to waste recycling and refining process, in particular to a process for refining residual mud and slag and its mixed product with cement. Background technique [0002] In recent years, with the development of sound and fast economic construction, the pace of urbanization is accelerating. In the process of updating urban facilities and rebuilding old cities, and people's living standards are improving day by day, there are more and more domestic garbage, resulting in residual mud The debris is also increasing day by day. These residues are usually landfilled in landfills to reduce environmental pollution, but the landfill treatment is difficult to meet the current rapidly increasing demand for residues. In addition, landfilling consumes a lot of land, garbage removal and transportation costs and landfill expenses, and will block the soil biological chain, causing serious pollution to the environment and bringing great harm...
