FIELD: recycling.SUBSTANCE: invention relates to processing of combustion products and can be used at thermal power plants and in boiler houses operating on coal fuels. Process line for processing of ash-slag wastes comprises ash-slag wastes batcher, connected to the mixer volume, connected to a source of a diluting medium by the supply line, classifier of ash-slag particles, means of classified particles fractions dewatered arrays discharge . Line is equipped with the first recirculating tank, which is connected to the output of the mixer by means of the pipeline equipped with the first pump. Drain nozzle of the first recirculation tank is arranged at its top edge and communicated with the mixer by the first drain pipeline. Outlet nozzle of the first recirculation tank is arranged at its bottom and communicated with the rotary disperser inlet nozzle, configured with a possibility of impact-abrasive pulp grinding, while its outlet nozzle is connected to the input of the first classification unit hydraulic cyclone, containing also the second hydraulic cyclone, second recirculation tank and a damping tank. Sand output of the first hydraulic cyclone is communicated with the damping tank, while its clay output is connected with the storage tank of clay fraction. Input of the second hydraulic cyclone and input of the second recirculation tank are linked by a connecting pipeline equipped with the second pump with the damping tank. Sand output of the second hydraulic cyclone is interconnected with the storage tank of heavy fraction, while its clay output is connected with slimes storage tank. Each of the storage tanks and the damping tank are equipped with the drain nozzle, arranged at its top edge and connected to the input of the settling tank, output of which is connected to the input of recycling water tank by means of the third pump with the first water line, output of which is communicated with the mixer by means of the fourth pump with the second water line. Drain nozzle of the second recirculation tank is arranged at its bottom and communicated with the damper tank by means of the second drain pipeline equipped with a valve. Line is equipped with a water source configured with a possibility of its supply to the first recirculating tank and the damping tank.EFFECT: technical result is expansion of range of fractionation of ash-slag wastes by the particle size, as well as reduced pollution of the environment.8 cl, 2 dwg |
