AI Technical Summary
In coal preparation plants, the sedimentation and flotation processes of coal slurry water often cannot achieve optimal efficiency at the same time due to water hardness issues. Traditional methods cannot effectively resolve the contradiction between sedimentation and flotation, resulting in low sedimentation efficiency or poor quality of flotation clean coal.
A resin hardness ion circulation system is adopted, which uses resin to adsorb and desorb hardness ions to achieve graded control of water quality entering the sedimentation and flotation units, allowing each unit to operate in its own favorable environment, including the flotation unit operating at low hardness and the sedimentation unit operating at high hardness.
It significantly improves the efficiency and quality of the entire coal preparation process, reduces operating costs, realizes closed-loop water resource recycling and reagent consumption, and ensures stable and reliable system operation, adapting to continuous production needs.
