Upgrading design of the existing coal slurry water treatment system in decentralized layout

The existing coal slurry water treatment system of the plant used to be low in efficiency because of the scattered layout of a multiple of small-sized thickening equipment. To address this issue, through redesign of process equipment layout and control mode, an innovative high-efficiency tailing water thickening process featuring the use of equipment connected in series for the first stage and in parallel for the second stage is finally developed. The thickeners and filter presses are all working under logic control through informationized integrated management and control platform. Practice shows that through the upgrading design, there can be seen much reduced volume of tailing water in inefficient circulation, Increased utilization rate of equipment working in coordination and slurry settling efficiency. And the thickeners and filter presses are made possible to operate in an unattended manner.
