ACTIVE CARBON PRODUCTION COMPLEX Russian patent published in 2001 - IPC

FIELD: production of active carbon from charcoal. SUBSTANCE: complex has apparatus for grinding and sorting of, for example, partially carbonized charcoal, activating furnace, apparatus for producing activating agent and activation container equipped with closure and charging and discharge device mounted on closure. Charging and discharge device is made in the form of tube joined with gas discharge device formed as sleeve with opening and opening stopper, and activating agent supplying device formed as spiral joined to tube. Hollow disk or concentrically diverging hollow bars are arranged in lower part of tube. Spiral, tube and upper part of disk or bars are made perforated, with section of perforations increasing in activating agent flow direction. Section of perforations and number of perforations are calculated from mathematic formula. Complex of such construction allows activated carbon with increased activated adsorption to be produced. EFFECT: simplified construction and improved quality of active carbon. 3 dwg
