Description

technical field [0001] The invention relates to a technology for preparing coal-water slurry from wastewater, in particular to a prediction and optimization system and method for intelligently determining the preparation scheme of wastewater-coal-water slurry. Background technique [0002] China has large reserves of coal resources, and coal occupies a high position in my country's energy structure. However, the average utilization efficiency of direct coal combustion is low, resulting in a waste of energy resources. The application and development of coal conversion technology has improved the utilization efficiency of coal and reduced the dependence of the energy market on oil and gas resources, and has been valued by countries all over the world. [0003] However, with the development and popularization and application of coal conversion technology, the treatment of wastewater generated in the process of coal conversion presents a situation of "two high dilemmas", that i...

Problems solved by technology

Moreover, in practical industrial applications, in most cases, various wastewaters are mixed and treated with large changes in properties, which makes the components of the mixed wastewater more complex and increases the difficulty of preparing stable coal-water slurry.

At present, there have been some achievements in the research on the slurrying characteristics of a single wastewater, but there is no report on the mixing and pulping of multiple wastewaters in the coal conversion industry
