Looking for recommendations for catalytic device systems for the sealed discharge of fine powder, or manufacturers
Thread Content
My plant is a catalytic unit with a capacity of 2 million tons per year; currently, the fine powder is bagged manually, which results in a high level of dust. I would be very grateful if my colleagues could share their solutions to this problem or recommend manufacturers of equipment equipped with sealed discharge systems
Your four rotating material legs are installed separately; in most cases, these four rotating legs are directly connected to the top of the three-rotating waste tank, eliminating the need for manual bagging!
We have a pipeline leading to the waste catalyst tank, but we use that tank to store balance agents; so even if they’re kept in the waste catalyst tank, they still need to be bagged eventually.
Do you four rotors need to recover so many details? We’ve been in operation here for 3 years, and we still can’t fill even one catalyst tank! Either the cyclone recovery effect in the previous stages isn’t good enough.......
That’s incorrect; a tank filled quickly with fine powder indicates that the cyclone separator ahead is working well. On another note, after modifying the centrifuge, there was more fine powder produced. When the centrifuge wasn’t working properly before, either the powder would escape through the chimney or end up in the slurry and be carried to the tank area.
If the primary and secondary centrifugation processes yield good results and there isn’t much fine powder in the system, then three or four stages of centrifugation will not result in excessive fine particles, so there’s no need to discharge the material for a long time
If there is a lot of fine powder, it might be because the balancing agent has been damaged; in fact, more agent still escapes, at least the amount of balancing agent that is discharged will be less. When two evils must be chosen between, picking the lesser one is still considered a good thing.
It means that the cyclone recovery efficiency in the earlier stages is not good.
Saying it was a momentary impulse is a bit one-sided; my apologies. Our fine powder tanks and valves are located on the second-floor platform; a rubber hose is connected below them. When unloading the fine powder, a four-wheeled vehicle is driven to beneath the hose, with tons of bags placed on the vehicle to collect the fine powder. When there is an excess of fine powder, the first reaction is that there is a problem with the primary and secondary centrifugation; after all, the human eye cannot determine exactly how many micrometers it is – it’s just an intuitive feeling that more fine powder is present ； The situation I’m describing is a bit special: the catalyst lacks sufficient strength and wears down into fine powder. As a result, it isn’t retained by the first and second centrifuges and ends up in the fine powder tank. This also leads to an increase in the amount of fine powder – it’s truly an excess of fine powder in this case. This problem can be solved simply by using a catalyst with higher strength; it’s much easier to handle than issues arising from problems with the centrifuges. The workload and construction difficulty of rotary splitting are greater than generally imagined.
