Technological line for processing slag waste - incineration of coal fuel

摘要

The invention relates to the field of disposal and processing the combustion products and can be used in thermal power plants and boiler operating on coal fuels. The production line is characterized in that the receiving bin is provided with a first active chopper placed in its cavity to the outlet, wherein, its output via the first conveyor is associated with metallokamnevydelitelem configured to additional grinding ash waste, thus, zoloshlakovyh output metallokamnevydelitelya by the second conveyor is connected a feeder-doser ash waste, in addition, the labeling agent ash particles formed as a hydrocyclone in, thus, peskovy input of the first of them connected to the pulp outlet of the mixer through a first conduit equipped with first sand pump, the output of light and the fine fraction of the first hydrocyclone via a second conduit connected to the inlet of the flotation installation, and peskovy output of the first hydrocyclone is open into the storage tank, whose output is connected to the inlet of disintegrator, the output of which is connected with the input of the second hydrocyclone Peskov, output light and the fine fraction of which communicates with the second conduit, and its Eskov output by the second sand pump in communication with the storage tank, moreover, yield floated material is the flotation installation communicates with a collection of unburned carbon, and a chamber outlet flotation unit communicates with the inlet of the hydrocyclone of the first clarification step, a fluid outlet which is connected to the inlet of the hydrocyclone second stage clarification, the , sand hydrocyclones outputs of the first and second stages of clarification communicated with a collection of ash fraction, wherein the fluid outlet of the second stage hydrocyclone clarified Ia communicated with a tank collecting the clarified water outlet through which the clarified water pump connected to the mixer and the water supply pipe to the upper portion of the first conduit, moreover, the first conduit is further communicated with the mixer by recycle conduit. In addition, metal-tile metallokamnevydelitelya output connected to drive the stone and metal inclusions. Additionally, flotation unit communicates with the source of the floating agent, preferably kerosene. In addition, a first active chopper is made in the form of parallel shafts mounted for counter-rotation in the hopper cavity before its outlet opening provided with a disintegrating knives. The technical result is expressed in enabling effective utilization of waste ash, unburned carbon by the removal and return of a corresponding part of the fuel in the process of combustion.
