Described liquid distribution trough is cylindrical shape, and surrounding is disposed with from top to bottom 6 groups of circular pores, and per group includes 7 Pore, pore aperture is 0.4～0.5mm.
Compared with prior art, it is an advantage of the invention that：By the flow path for changing gas-liquid fluid, rotor is made full use of Interior radial direction and axial space, improve gas-liquid situation pockety, effectively extend gas-liquid contact time；Meanwhile, by increasing To gas level of disruption, mass transferring in gas phase efficiency is improved.
It is specific as follows：
（1）Baffle upper plate and chin spoiler it is radially equidistant from be fixed on quiet disk and Moving plate, gas radially ecto-entad Successively alternately through baffle upper plate and chin spoiler, liquid is then radially led alternately through chin spoiler and above successively from inside to outside Stream plate.Liquid enters into liquid distribution trough Jing after the pore of 0.4mm sprays, and forms the larger spraying of specific surface area, effectively increases Add gas-liquid interface area, enhance the gas-liquid mass transfer effect of equipment.
（2）To after the chin spoiler with acanthopore, under the influence of centrifugal force, liquid is in acanthopore and deflector for spray impingement Upper to form thin liquid film rather than laminar flow is formed on deflector, partially liq impinges upon next baffle upper plate through acanthopore, greatly Part increased the gas liquid interfacial area on each chin spoiler along chin spoiler flowing；Meanwhile, gas can be by acanthopore Liquid film blows brokenly, draws thinner by liquid film, there is angle between chin spoiler and Moving plate, and liquid under the influence of centrifugal force, is passed through Acanthopore forms liquid film in the outside of chin spoiler, increases the surface utilisation of gas liquid interfacial area and deflector.
（3）Liquid strikes baffle upper plate by the fluid passage between upper chin spoiler, and liquid is in aperture and deflector Upper formation liquid film and tiny drop, as in chin spoiler, gas blows broken the liquid film of acanthopore, by the thinner of liquid film drawing, Further increased gas liquid interfacial area；Partially liq is impinged upon on next chin spoiler through acanthopore, most of liquid Drop under gravity on Moving plate, be then thrown on the chin spoiler with acanthopore again and form very thin liquid film, such as Going down repeatedly for this, until liquid is thrown out of rotor, formed "（）" type passage, liquid in the rotor constantly focus on and quilt It is broken, gas-liquid contact surface is have updated, and space availability ratio is substantially increased, and fluid flow is largely extended, prolong Gas-liquid contact time has been grown, the gas-liquid separation effect of equipment has been enhanced.
（4）In centrifugal field, gas is constantly sheared when the fluid passage between acanthopore and upper chin spoiler is passed through And dispersion, counter current contacting, the strong mixing of generation, the interaction between gas-liquid between the passage that deflector is formed with liquid Strengthen, gas phase less turbulence strengthens, mass transferring in gas phase process is strengthened.
（5）Filler need not be filled, the cost of manufacture of device is reduced, operation energy consumption is reduced, and rotator inertia is aobvious Write and reduce, operation stability is improved, can continuously run for a long time.
