Method for the Selection of Combustion Ash on Coal Ash in the Ash Pond

摘要

The subject innovation is to install the hopper (Hoper) (one) and the chute (Shute) (2) the vibratory screening apparatus for use in order to collect the aggregates, etc. The primary separator is usually quarries as ash screening method of the thermal power plant fly ash landfill controlling the emission and concentrations, and a special coating to prevent corrosion and, using two polyurethane networks are selected gravel. Secondary screening device is the free fall velocity in the storage tank 8, a plurality of screening tank (9a, 9b, 9c) and adjustment of the forced convection rate of water by installing the sedimentation tank (10) to use the water free fall gravity selection method a method for screening and control. Can prevent serious social problems are enough to make the landfill depletion difficult the existence of a thermal power plant, can prevent the destruction of the natural environment, prevent the excessive aggregate extraction.
