Title: Filter replacement lifetime prediction

Abstract

Methods and systems for predicting a filter lifetime include building a filter effectiveness history based on contaminant sensor information associated with a filter; determining a rate of filter consumption with a processor based on the filter effectiveness history; and determining a remaining filter lifetime based on the determined rate of filter consumption. Methods and systems for increasing filter economy include measuring contaminants in an internal and an external environment; determining a cost of a corrosion rate increase if unfiltered external air intake is increased for cooling; determining a cost of increased air pressure to filter external air; and if the cost of filtering external air exceeds the cost of the corrosion rate increase, increasing an intake of unfiltered external air.

  • A filter apparatus including a housing having a discharge apparatus for removing granular gas treating material from the hopper of the housing. The discharge apparatus includes a baffle plate extending across the hopper between the side walls of the housing which defines a material discharge channel opening into the interior of the hopper through a pair of parallel slots extending along the edges of the baffle plate, a conveying gas inlet aperture in one of the side walls opening into one end of the conveying channel, and a gas treating and conveying gas outlet aperture in the other side wallmore » opening into the other end of the conveying channel of a larger cross-sectional area than the conveying gas inlet aperture to promote progressive aspiration of the treating material from the interior of the hopper commencing at the end of the channel proximate the conveying gas inlet aperture.« less
  • Disclosed is an apparatus for automatically consolidating a filter or, more specifically, an apparatus for drawing a volume of gas through a plurality of sections of a filter, where after the sections are subsequently combined for the purpose of simultaneously interrogating the sections to detect the presence of a contaminant. 5 figs.
