Air Filtration System
Colleagues, we are moving premises which allows me to redo my air fitlration system. and I am look for suggestions to improve our air handling system. We do twin wire arc spray, mainly Aluminium and zinc with a little bit of SS/ Monel / CuNi. We have been using a 24 cartridge suction air filter, and find that the existing cartidges are fine for blasting dust (steel grit), ok for Zinc, they clog very easily / quickly with Al dust. We have a reverse pulse air jet cleaning system on the filters, but the Al dust is so "light" the filters do not self clean. (we can be running 2~3 arc guns at the same time in the same filter system, so the dust volumes can be significant)
Has anyone any suggestions on ways to improve - a cyclone seperator before the filters ?
