Description

Technical Field

[0001] The utility model relates to the technical field of fly ash processing, and more specifically, to a dust suppression device for fly ash processing. Background Art

[0002] 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. However, fly ash can be used as a resource, such as as an admixture for concrete.

[0003] Since fly ash particles are tiny, dust is easily generated during the processing of fly ash, which easily leads to more dust in the air, affecting the air environment, and dust reduction operations are required;

[0004] In the prior art, dust reduction operations are mainly performed by spraying. Although dust reduction can be achieved, secondary dust is easily generated after the water evaporates, resulting in poor dust reduction effects during fly ash processing.

[0005] Some dust suppression devices collect dust through the cooperation of a collection box and a fan. However, the air suction structure is fixedly installed, which is not convenient for suction and cleaning of dust at different heights. Utility Model Content
