DYNAMIC ADSORPTION INSTRUMENT Russian patent published in 2001 - IPC

FIELD: devices for examination of the process of adsorption, applicable for selection of adsorbent and optimum condition of adsorption purification of air from toxic impurities in chemical, metallurgical, semiconductor and other branches of industry. SUBSTANCE: the dynamic adsorption instrument has an adsorption column, filters, pressure regulators, flow meters, ejectors, swing cranes, air humidifier. The instrument is provided with a diffusion proportioner, mixing chamber and a gas analyzer. The diffusion proportioner has chamber with substance to be adsorbed connected to a cylindrical tube, inserted in which in a spaced relation is coaxially moving rod. Substance proportioning in the diffusion proportioner is accomplished through an annular gap between the walls. The mixing chamber has external and internal cavities, whose walls have orifices, and the external cavity is provided with an air inlet pipe connection. EFFECT: enhanced accuracy of determination of adsorption characteristics of sorbent. 3 dwg, 1 tbl
