Secondary dust source

Dust on the floor, walls, building components, as well as on the boiler itself and its equipment, along with the dust that accumulates after minor repairs to the equipment, is not cleaned regularly and promptly, thus creating secondary sources of dust. Why clean it? It’s just like doing housework at home. As for how to clean it, that naturally depends on the nature of the dust and the design of the equipment; methods for removing dust include using a vacuum cleaner or manual cleaning, among others.

According to available information, secondary dust sources refer to particulate matter that settles around the site and can cause dust pollution again under certain conditions. To eliminate and control these secondary dust sources, it is necessary to regularly and promptly clean away the dust that has settled on the ground, walls, building components, as well as on boilers and equipment, as well as the dust that accumulates after maintenance work on such equipment, in order to prevent the formation of secondary dust sources. Dust prevention measures: 1. Processes and materials: Choose processes that generate little or no dust, and use materials that are harmless or cause minimal harm; for example, opt for wet processing methods instead of dry ones. 2. Limiting and suppressing dust generation and dispersion: Use enclosed pipelines for transportation, as well as enclosed automatic (mechanical) weighing systems ； Reduce the drop height of materials, etc ； For hydrophilic, weakly sticky materials and dusts, measures such as heating, spraying, and vapor spraying should be employed as much as possible ； Reduce secondary dust sources. 　　3. Ventilation and dust removal

Simply put, it is when dust generated once is collected and settled, only to be released again due to natural and human factors. For example, when dust in nature rises again, it is also called open source ； Industrial dust may rise again when it is unloaded after being collected. Wait.
