Topic tags/keywords: dust deswirl thien

Looking at this diagram (deswirl devices) I cannot figure out how to make one of these and where and how it works with the thien’s dust collector. The bottom sketch doesn’t seem to clarify the top sketch at all to me.

If someone has done this project I sure would like to see it in detail so I can understand how it all works together.

I know I’m asking a lot so if there is no interest in this just let it go and I’ll understand. larry

This is where I am coming from: http://www.jpthien.com/smf/index.php?topic=1048.0

This is a basically the same thing.

In the top pic the line right below the point is the top of the vane and the next line down is the bottom of the vane.

I can draw a pic in minute or two to help.

From what I gather the 3 fins straighten out the cyclone action of air moving through a pipe and the teardrop deal in the middle hold the fins and is shaped that way to cause as little obstruction to airflow as possible.

How this helps with dust collection I have no clue.

Hope this helps a little. Good luck.

If you had a turbine (propeller) type fan it is good to have airflow as straight as possible going into the fan. This would help in the fan inlet.

If you have a vertical axis mounted centrifugal fan centered above the cyclone outlet and your fan rotation is the opposite of the cyclone rotation this would help.

Otherwise, I don’t see enough advantage in the short runs involved and the type of pipe or ducting being used to justify this.

Frige, the drawings help a lot, now to comprehend it all. Thanks.

Crank, the claim is that it keeps the air in a cyclone pattern and therefore increases the air pressure and uses less energy while it cuts down on the dust as well due to the continued constant air pressure. Thanks.

I find the paper interesting but way over my head and would like to put something like this in as an experiment just for me.

Wish sometimes I had studied to be an engineer instead of fooling my life away in a govt office.

No you don’t. Most over worked, under paid and under appreciated occupation existing. Been there done that for 40 years. Got nothing to show for 40 years of working 60 hours a week except the personal satisfaction of knowing there is 300 guys with jobs I created supporting families.

I guess we all have the frustrating part of our occupational choice, but watching money spent to favorites, that belong to and have been take from the tax payers, is almost more than a person can stand if they are honest.

I think we all have our story so I’ll end at that. Thanks for creating jobs, we never created anything but the need for more money. At least you have one thing that no one can take away from you… what it is that you have learned.
What I have learned I wish I could get out of my head.
