I'm looking at constructing this new extraction system(see attached) as I'm going to be taking on alot more scrap to process and feel the system I currently have is not going to be able to cope with the extra work loads.
So, starting from the main extraction hood, I'm going to get this made of Aliminuim sheet at 2/3ft long and about 1.5ft wide, I'll need to get this painted to prevent any corrosion from any gasses. I might also have to make three holes on the top of the hood to allow for three flexi pipes to connect into a cross tee fitting and then into the main 4" pipe that would then go through the whole system. The reason I was thinking of using flexi ducting to connect to the top of the hood is so that I could adjust the hight of the hood if required. I am going to use 8" pipe for the scrubber and near enough fill it with hair curlers and also, at the bottom of the scrupper, have a one way valve so that the solution sprayed at the top of the scrubber can drain out of the scrubber back into the main vessle from where the solution gets pumped out from, this vessle is going to be lower than the main system so gravity can do its thing when it comes to draining out the solution from the scrubber. Also, as per drawing, above the scrubber, I'm going to fit a 90degree bend in and then after about a foot of it running horizontal, I'm going to fit another 2ft of 8" pipe with a top and bottom access panel in, and in this section, I am going to fill in with charcoal brickets inside of plastic netting so that the partialy neutralised gasses can flow thourgh this final section to try and neutralise a bit more of the gasses but also, hopefully neutralise any strong smellies to keep the naighbours happy
So, any thoughts would be grately welcome and any advice if you think I've missed anything crucial.
One thing I do need clarified, for the solution thats going to be sprayed in from the top of the scrubber, I'd prefer to use Sodium Carbonate mixed with water. I'd prefer to stay clear of Sodium Hydroxide as I have to kids that would be in the garden in the summer months and feel really concerned about spillage while they are near
