Application of Coagulant and Flocculant Combined System in Coal Preparation Plant
In the normal production process of a coal preparation plant,the slime water does not settle,so it has to stop and wait,and the truck can only be started again after the clarified water reaches a certain amount.Moreover,after a period of normal production,the coal slurry water will not settle again,and there will be no clear water in the concentration tank,forcing the plant to stop again to wait for the coal slurry water to settle,seriously affecting the continuous production of the plant.Based on this,an experimental plan was established through analysis to combine coagulants and coagulants for use in the system.The coagulants were pre added before the coagulants were added,and the fine particles were pre aggregated into larger particles.Later,the coagulants were resettled to reduce the consumption of coagulants,accelerate the settling rate,and improve the treatment effect of coal slurry water.
