摘要
A system for collecting ultra fine fly ash from a dry fly ash removal system includes providing a bagfilter transport conduit for each bagfilter of the system. A vacuum shutoff valve is positioned in each bagfilter transport conduit The bagfilter transport conduit is selectively connected to an educator that is, in turn, selectively connected to a blower. The blower creates a vacuum flow in the transport conduit that draws the ultra fine fly ash from the bagfilter and deposits the ultra fine fly ash in a collection bin. This system allows a dry fly ash removal system to segregate fly ash by size and separately collect the ultra fine fly ash from the larger fly ash particles. The ultra fine fly ash has been found to be commercially valuable as a concrete admixture filler in various applications.
