The present invention discloses a spindle-shaped
structured packing, which comprises at least a packing layer comprising a plurality of horizontally-placed spindle-shaped special-shaped pipes connected in parallel, wherein the plurality of the horizontally-placed spindle-shaped special-shaped pipes connected in parallel form a plurality of parallel channels with collection sections, laryngeal orifices and dispersion sections, the cross section of the spindle-shaped special-shaped
pipe is the spindle shape, the top portion and the lower portion of the spindle-shaped special-shaped
pipe are the arc shapes, and the
radius of the arc on the top portion is larger than the
radius of the arc on the lower portion. Compared with the existing
structured packing, the spindle-shaped
structured packing of the present invention has advantages of high
mass transfer efficiency, simple structure, small size,
fouling resistance and low pressure drop, has less gas-phase liquid foam entrainment after the
mass transfer reaction, is suitable for the gas-liquid two-phase
mass transfer and reaction processes, especially for the dust removal and desulfurization treatment of
flue gas and process
exhaust gas, and can be widely used in the fields of
petrochemical industry,
environmental protection and the like.
