Collection of explosive dusts
Thread Content
During homogenization, weighing, and loading into the furnace, a small amount of powders such as zinc powder, phosphorus powder, and zinc phosphide powder may spill. When using a vacuum cleaner to collect the material, there have been two explosions in the factory caused by the vacuum cleaner sucking up zinc powder and aluminum powder; therefore, there are concerns that using a vacuum cleaner could lead to explosions. Using a broom or mop won’t clean things properly, and it will also scatter waste everywhere. Would connecting a pipe to the Donaldson dust collector to use suction instead of a vacuum cleaner prevent explosions, or do anyone have any other good suggestions?
Use electrostatic precipitators and water curtains to eliminate static electricity
I think you’re thinking in the wrong direction – where to work to get exposed to sunlight, and then figuring out how to collect something that won’t explode? The root cause lies in the fact that the zinc powder and phosphorus powder fall off during the handling process; therefore, the focus should be on ensuring that they do not fall off during handling, rather than on subsequent processing. What do you think?
Human plans cannot match fate’s decisions; even if nothing is spilled, extremely fine dust can still get airborne, and dust will inevitably accumulate on the floor
Are there any suitable products you can recommend?
Human plans cannot overcome fate’s decisions, which means that accidents are inevitable; I think you also feel that this is unavoidable, right? But my point is that measures should be taken in the early, middle, and late stages before the task begins, so as to identify and address each safety hazard; even if it’s not perfect, this approach can minimize potential harm. On the other hand, the original poster’s idea is to disclose everything in advance and deal with the issues afterwards, focusing on the measures to take, which seems to put the cart before the horse. Personal opinion
It’s just about collecting the dust and particulate matter that falls to the ground; what kind of accident is that?
Air intakes are installed at each dust source, and the air is then sent to the dust collector through pipelines; the pipelines as well as the dust collector are equipped with explosion-proof membranes. Of course, different types of materials use different dust collectors to facilitate recycling. As for the vacuum cleaner exploding that you mentioned, it’s very likely that the concentration was within the explosive range. At this time, it is necessary to increase laboratory ventilation. It is also taboo to use a vacuum cleaner with zinc powder and aluminum powder mixed together.
Leaks and spills are all potential hazards, and potential hazards can lead to accidents; everyone has a different understanding of what safety means
