摘要： A method and apparatus fluidizes solid deposits of coal tar sludge, such as coal tar decanter sludge or coal tar tank sludge to a relatively homogeneous mixture of solids dispersed in liquid. The coal tar decanter sludge received from the coke oven, including approximately 10 to 50% by weight coal and coke solids, is mixed with a suitable coal tar solvent heated to a temperature sufficient to partially solubilize and reduce the viscosity of the coal tar portion of the coal tar decanter sludge to provide a pumpable dispersion of solids dispersed in a diluted coal tar mixture. Agglomerates of coal and coke solids held together with coal tar are reduced in size and can be recirculated to a sludge mixing vessel. The diluted coal tar mixture is pumped to recirculate it to the sludge mixing vessel after impacting and shearing the solid agglomerates to reduce the solids particle size.

摘要： A method and apparatus fluidizes solid deposits of coal tar sludge, such as coal tar decanter sludge or coal tar tank sludge to a relatively homogeneous mixture of solids dispersed in liquid. The coal tar decanter sludge received from the coke oven, including approximately 10 to 50% by weight coal and coke solids, is conveyed into a sludge mixing vessel where it is deposited onto a liquid-permeable support member or screen having a predetermined maximum screen size. A suitable coal tar solvent in the sludge mixing vessel is heated to a temperature sufficient to partially solubilize and reduce the viscosity of the coal tar portion of the coal tar decanter sludge to provide a pumpable dispersion of solids dispersed in a diluted coal tar mixture. Agglomerates of coal and coke solids held together with coal tar fall through the screen when sufficient coal tar has solubilized and the solid agglomerates then are reduced in size for recirculation to the sludge mixing vessel. The diluted coal tar mixture is pumped to recirculate it to the sludge mixing vessel after impacting and shearing the solid agglomerates to reduce the solids particle size.
