Description

Technical Field

[0001] The utility model relates to the technical field of hopper dust removal, in particular to an environmentally friendly dust removal device special for a hopper. Background Art

[0002] At present, many ports and terminals are still using traditional bulk hoppers, which will generate a lot of dust when in use, thus polluting the surrounding environment. To avoid this phenomenon, spray dust suppression or traditional bag dust removal methods are usually used on the hoppers. However, the spray dust suppression method will increase the moisture content of the goods, which may not only affect the physical properties of the bulk materials, such as fluidity, bulk density, etc., but may also cause bulk materials to agglomerate and stick during transportation and storage, thereby affecting loading and unloading efficiency and use effects. In addition, the water mist particles generated by water spray dust suppression technology are large and often cannot be well combined with dust particles, which leads to low dust suppression efficiency, especially in high wind speed or high dust concentration environments. The dust suppression effect is greatly reduced; traditional bag dust collectors are not specially designed for bulk hoppers, occupy a large area, and in order to achieve a certain effect, the dust collector power has to be increased.

[0003] In order to meet the high standards of environmental protection and efficiency of modern ports, a special environmentally friendly dust removal device for hoppers is proposed. Utility Model Content
