The Feld Scrubber
Baltimore: The Bartlett Hayward Co., (1923). First Printing. Hardcover. 8vo, publisher's cloth, very good, previous owner's name in pencil. 55 pp, illustrated, including 5 folding diagrams. The feld scrubber removed pollutants from gases produced in the production of potash and other fuels. Uncommon, with OCLC locating a single holding, Hagley in Delaware. The feld scrubber was spray tower counterflow scrubber used to clean the flue gas of a copper smelter. Unique application of this unit is that the participates recovered are reprocessed for their zinc content and the gas is processed for elemental sulfur. A brief history is given of the failures experienced with dry centrifugal cleaning, wet baffle cleaning, bag filters, and electrostatic precipitation. The Feld scrubber with which success was finally achieved is a seven layer system in which primary washing is performed in the lower three chambers, separation in middle section, and cooling and dehumidification is performed in the upper three chambers, although this may be varied at the will of the operator. Washwater is admitted at the selected level and atomized by the rotary motion of the perforated central cones and again by impact with the outer wall. Does that make sense? Very good. Item #H40697
