I plan to run a hose from the bottom of one drum to the top of the other drum. I hope the top tote is high enough to push the fuel through the drums on the same level.
When the tote is full it should provide more than ample "push" to feed the drums side by side, although once it gets more towards empty it may not unless during a run as syphoning will be a contributor to the flow rate. You could set up a metering pump between the tote and drums and always have the exat same flow rate no matter what the volume inside the tote is. But then with a meter pump you could have 'em all on the floor too.
My set up use a by-pass system and that seems to work just fine at pushing the biodiesel into the top of the drum and then from the bottom back up to the top of the first resin tank and then over to the next resin tank and through a 2 micron CAT filter.Rememebr that the water purification tanks I use utilise reverse flow where the fuel goes in the top and then must filter down and then come back up a central tube inorder to leave the tank (same principle as a fuel filter) and it does this twice after leaving the bottom of the drum. Soap is zero PPM.
The pressure on the flow is negligeable; RolfQuo uses air to move the fuel around at about 2PSI. Once it gets going it keeps on flowing.
FF: nice set up.Congrats on leaving the world of the waterlogged :-) What is supposed to be the purpose of the centrifuge?
Pierre, I just asked for screen door screen. I do not know the size.
Legal Eagle, the centrifuge is there because I have it, and I was thinking it might catch any resin or soap that could be in the fuel. I did find a very very small amount of brown goo in the CF after running the first 240 gallon batch through the system. I am thinking resin from the wood. I could be wrong.
It would definetly be wood resin. If you start with a soap count of 1,000PPM or lower a single pass should net you a zero count with one pass as long as the flow rate is moderate. If you need the centrifuge for another job you can do the same thing with a filter bag. McMaster Carr has all kinds.
I added the second drum in series. Just ran a hose from the bottom of the first drum to the top of the second drum. Works well. I am not sure if the second drum will siphon the fuel from the first drum when the tote gets empty.
I need to add an air bleed valve with sight tube to the top of each drum. The tube will need to extend above the top tote so I can fill the drums without standing there watching for over flow.
