Abstract

The invention relates to an inner sleeve plate structure of a packed fractionating tower. The inner sleeve plate structure comprises at least one inner sleeve plate; the inner sleeve plate structure is along a tower height direction; namely, at least one inner sleeve plate is fixed in the tower along the wall of the packed fractionating tower. The inner sleeve plate structure is used for changing an overflowing area of a packed bed layer and improving gas-liquid distribution condition in the packed bed layer. The inner sleeve plate structure increases mass transfer efficiency, improves process performance of the fractionating tower, increases spraying density above the packed materials, prevents high temperature poor quality oil from coking in the packed bed layer, and reduces equipment investment.

Description

technical field [0001] The invention relates to an internal part of a fractionation tower, in particular to an inner sleeve plate structure of a packing fractionation tower. Background technique [0002] As an important mass transfer separation equipment in petroleum, petrochemical, pharmaceutical and other fields, packed fractionation column is widely used. Packed tower internals mainly include packed bed, feed distributor (distribution pipe), oil collection tank, gas distributor, liquid phase distributor and other structures. [0003] In engineering practice, the gas-liquid load of each packed bed in the packed fractionation column often has a large difference, and the selection of the tower diameter must meet the requirements of the maximum loaded packed bed, which will lead to some packed beds or gas-phase loads Too low, or the liquid phase load is too low, or both gas and liquid loads are low, resulting in low mass transfer and heat transfer efficiency in the packed be...
