MASS-TRANSFER COLUMN Russian patent published in 1998 - IPC

FIELD: designs of packed mass-transfer column for reaction of gas (vapor)-liquid system intended for processes of absorption, rectification, in particular, for small-tonnage production of high-purity chemical reagents; may be used in chemical, petrochemical, food and other industries. SUBSTANCE: mass-transfer column has vertical cylindrical body, arranged in tiers distributing conical lattice with perforations in the form of arched slots with tangentially directed axes and central holes at tops through which axisymmetrical vertical rod is installed and spot-welded to tops of conical lattices. Outer diameter of conical lattices is smaller than inner diameter of body to let free passage. The lowest and highest lattices are confined by detents. Poured on each lattice is packing whose layer height exceeds the half distance between lattices in height. Novelty consists in fastening of distributing conical lattices to vertical rod, restriction of downward motion of lower lattice, and upward motion of upper lattice, possibility of column transportation in assembled state, possibility of column transportation in assembled state, possibility of column operation within a wide range of loads without mechanical carrying away of packing by flow of gas (vapor) and liquid. EFFECT: higher efficiency. 4 dwg
