Dust collector to filter Outside Air
Dust collector to filter Outside Air
(OP)
Mini building inside of steel mill with dusty atmosphere.
Anyone ever try to prefilter the air with a dust collector type device to avoid filter plugging and lack of maintenance changing filters?
The building will house electronics which do not like dust. The client wants to pressurize the rooms to keep dust out. Due to location, running a fresh air duct to the ouside of the building is prohibitive. Heat is removed with A/C.

There is a mixture of cabinet mounted devices, servers, ups, etc..., as well as lights,transformers and occasional people.
A large load in a little container building, mostly sensible heat.

Just looking at alternatives right now. The client is not good at changing filters, so either they will create XS pressure or will be thrown away.
The atmosphere is very dusty-visibly.

Thinking out loud, how about an insect screen to catch the larger particles? It might work if you have larger particles, and someone could clear it with a wave of their hand if accessible. We put an insect screen in at a paper recycling warehouse, but it also helped that the foreman and crew working there took an active role in changing the filters too.

To Quark: Can you be more specific? Let us know some description of what you mean? Some sites, some material, some data related? Is that possible? I'm in a middle of a similar problem, which I will share with the Forum.

The system consists of bag filters and air flows outside in. A compressed air jet strikes the filter bags with a specified time interval to loosen the particles from the bags and subsequently bagged out. We generally use them in pharmaceutical tablet manufacturing facilities.
But on a second thought, cyclone separators seem to be better option in a steel manufacturing environment. Perry's chemical engineers handbook (chapter 19) deals with cyclone separators elaborately. I faintly remember downloading an excel spreadsheet for cyclone separator design. If I can find it, I will send it to you provided I get your e-mail id. (PS: Don't expect it sooner

To QUARK: Yes, I would be interested in the spreadsheet.
