Cleaning of the molten sulfur underground tank
Thread Content
Dear everyone: The underground tanks used for melting solid sulfur contain a lot of debris (sulfur slag) within them. Once the sulfur slag at the bottom of these tanks cools down, it turns into something similar to concrete. To clean it out, people usually use pneumatic hammers to break it up before lifting it out. Is there any simpler and less labor-intensive method? If a large amount of cold water is poured into the underground tank while stopping the steam insulation of the coil, it might make it easier to remove the sediment using a pneumatic hammer.
I think it would be worth considering hiring a professional cleaning company; from what I understand, they use high-pressure water along with a device for spraying water (or paste).
It has some effect, but the results are not significant; the underground channels are difficult to clean anyway. It is recommended to clean them promptly and not delay it for too long.
The sulfur slag becomes too hard after solidifying; it is extremely difficult to drill through it layer by layer using a pneumatic chisel after it has cooled and solidified. It is recommended to maintain a temperature such that the sulfur slag does not solidify while it is being removed
Here is a simple method: stop the steam cooling, add water when sulfur has just turned solid, in order to cause the sulfur residue to foam; then remove the added water and scoop it up using a grab truck. It’s very convenient and fast. For areas that the grab vehicle next to it cannot reach, it’s sufficient to loosen them with a pickaxe.
