Fly ash is the fine ash collected from the flue gas after coal combustion. It is the main solid waste discharged by coal-fired power plants. If a large amount of fly ash is not treated, it will produce dust and pollute the atmosphere. If it is discharged into the water system, it will cause river siltation, and the toxic chemicals in it will also cause harm to humans and organisms. Fly ash dryer provides a good development prospect for the comprehensive utilization of fly ash.

  The fly ash dryer consists of three parts: heating system, heat exchange system and ventilation and dust removal system.

  Heating system: This part adopts hot air furnace technology, which has sufficient heat, good heat transfer effect and simple structure.

  Heat exchange system: This part is the drying drum, which is equipped with lifting plates and the lifting plates are staggered in a spiral shape. During the working process, the lifting plates repeatedly scatter materials, making the heat exchange rate extremely high.

  Dust removal system: This part is equipped with a dust collector. Because the fly ash particles are fine, the density is small, and the weight is light, after drying, it is easy to be carried away by the air flow under negative pressure, resulting in changes in the fluid medium. At the same time, the dust-containing gas has a large amount of moisture. If it is sucked out by the induced draft system and discharged into the atmosphere, it is easy to cause resource waste and environmental pollution, so the dust is collected uniformly by the dust collector.
