ADSORBER Russian patent published in 2000 - IPC

FIELD: cleaning gases by means of adsorbers; gas cleaning equipment; metallurgy, chemical and other industries. SUBSTANCE: adsorber has vertical housing divided into sections by means of perforated zigzag partitions, thus forming contractions and diffusers alternating in staggered order; upper and lower grids, are supply and gas discharge branch pipes; gas supply branch pipe is made in form of truncated cone from elastic-flexible material. Inner surface of narrowing cone has helical grooves located longitudinally; these grooves are made in form of dovetail; discharge ports having similar diameter are located at one level in direction from larger base of gas supply branch pipe towards its lesser base; they are smoothly distributed among helical grooves; their diameter increases with distance from larger base of branch pipe towards its lesser base; lesser base of gas supply branch pipe is blanked off with elastic-flexible material. EFFECT: enhanced efficiency of gas cleaning both at constant and varying loads; efficient use of space occupied by adsorbent at equalization of hydraulic resistance in sections; reduced usage of metals; improved quality of gas cleaning. 5 dwg
