Gas purifying adsorber - has vertically movable adsorbent bed-retaining inner screen

摘要

A gas purifying adsorber is rotationally symmetrical about a vertical central axis and consists of a housing contg. an annular adsorber bed filled with flowable adsorbent retained by inner and outer screens connected at their bottom by a gas-impermeable bottom plate. The novelty is that the outer screen is fixed to the housing, while the inner screen is vertically movable. ADVANTAGE - Thermal expansion and contraction of the outer screen and the adsorbent does not cause relative movement of the screens so that undesired wear is avoided.
