Problems solved by technology

[0002] With the progress of society and the acceleration of enterprise production, more and more waste residues are produced. As a kind of waste produced by industrial combustion equipment, the current treatment methods for coal residues are mainly natural cooling or landfill, which will not only cause Resources are wasted, and it will cause secondary pollution, seriously occupying land resources and polluting the ecological environment, and there is a lack of treatment equipment for coal slag in the market, which makes the production cost of enterprises increase day by day, which is not conducive to the development of circular economy

Abstract

The invention belongs to the technical field of waste slag treatment, and provides a high-temperature coal slag classification screening and waste heat recovery device. The device comprises a coal slag classification screening mechanism and a coal slag waste heat recovery mechanism. The coal slag waste heat recovery mechanism wraps the periphery of a coal slag classification screening shell. The coal slag classification screening mechanism automatically carries out classification screening on coal slag through the gravity settling action. Small-particle fine coal slag is screened to slide downto a fine coal slag collection chamber from a fine coal slag recovery ramp, and large-particle coarse coal slag rolls to a coarse coal slag collection chamber from a filter screen ramp and a coarse coal slag recovery ramp. The coal slag classification screening mechanism can screen the coal slag into the coarse coal slag and the fine coal slag; and meanwhile, after the coal slag enters the devicefrom a feeding bin, heat of high-temperature furnace slag is transmitted to a heat exchange pipeline in a radiant heat exchange manner, and the waste heat utilization efficiency can be improved. Thedevice can effectively overcome the technical defect of lacking a device capable of achieving efficient and environment-friendly recovery treatment of the coal slag at present.

Description

technical field [0001] The invention belongs to the technical field of waste slag treatment, in particular to a high-temperature coal slag classification screening and waste heat recovery device. Background technique [0002] With the progress of society and the acceleration of enterprise production, more and more waste residues are produced. As a kind of waste produced by industrial combustion equipment, the current treatment methods for coal residues are mainly natural cooling or landfill, which will not only cause Waste of resources, and will cause secondary pollution, seriously occupying land resources and polluting the ecological environment, and the lack of treatment equipment for coal slag in the market makes the production cost of enterprises increase day by day, which is not conducive to the development of circular economy. [0003] To sum up, there is currently a lack of an efficient and environmentally friendly device for treating coal cinders. Therefore, it is a ...
