Combined type baffling revolving bed mass transfer and consersion unit
Technical field
The invention belongs to mass transfer, reaction technology field in super gravity field, specially a kind of combined type baffling revolving bed mass transfer With consersion unit.
Background technology
High-gravity technology is one of typical chemical process reinforcement technique, greatly enhance gas-liquid mass transfer, heat transfer with it is anti- Answer process.In high-gravity rotating bed, liquid is formed surface area greatly and constantly updated by high-speed rotating filler shearing-crushing Drop, brin and liquid film, contacted with the gas across filler, enhance the microcosmic mixing of gas-liquid, make mass tranfer coefficient improve 1~ 2 orders of magnitude have many advantages, such as that liquid flooding is high, residence time of material is short.It is high-gravity rotating bed to be applied to by development for many years Rectifying, prepares the processes such as nano material, dedusting at desulfurization, becomes one of the effective way of chemical process reinforcing.
It is high-gravity rotating bed it is small be one of its advantage, but the flow of gas-liquid is also limited in certain space, connect The tactile time is short, does not utilize mass transport process.During existing major part is high-gravity rotating bed, gas-liquid is unevenly distributed so that gas not with Liquid contact will overflow, and influence mass-transfer efficiency, be only capable of strengthening mass transfer in liquid phase process, and since gas is draged by filler friction The effect of power, as solid rotation in rotor, gas phase interface cannot quickly update, but also mass transferring in gas phase is less efficient.
Invention content
The present invention is unevenly distributed and for gas-liquid existing in existing design since gas is by filler frictional drag Effect gas phase interface cannot quickly be updated caused by mass-transfer efficiency low problem, provide a kind of combined type baffling Revolving bed mass transfer and consersion unit.
The present invention adopts the following technical scheme that realization：Combined type baffling revolving bed mass transfer and consersion unit, including quiet disk, Liquid distribution trough, liquid inlet tube, gas outlet tube, baffle upper plate, chin spoiler, gas inlet tube, Moving plate, rotary shaft, liquid Body outlet and housing, it is characterised in that：Quiet disk and Moving plate are placed in housing, and quiet disk is equipped with different concentric of several diameters Cyclic annular baffle upper plate, evenly arranged circular aperture is provided on baffle upper plate, and Moving plate is equipped with several round table-like lower water conservancy diversion with one heart Plate is provided with evenly arranged acanthopore on chin spoiler, and baffle upper plate and chin spoiler are staggered, and quiet disk is consolidated with gas outlet tube Fixed to be connected, Moving plate is fixedly connected with rotary shaft, and rotary shaft one end passes through housing and seals therewith, and acanthopore includes logical on chin spoiler Hole and through-hole top edge perpendicular to chin spoiler or relative to the acclivitous hangnail of chin spoiler.
The gas inlet tube and liquid outlet tube is set on housing, and liquid distribution trough is connected with liquid inlet tube, Liquid inlet tube is arranged in gas outlet tube.
The baffle upper plate material is stainless steel or polypropylene plastics, and chin spoiler material is stainless steel or polypropylene plastics Material.
The baffle upper plate is equally spaced, adjacent baffle upper plate spacing d1It is the 1/12~1/10 of Moving plate length D, on Deflector height d3For adjacent baffle upper plate spacing d12.4~3 times, baffle upper plate and Moving plate spacing d4For adjacent baffle upper plate Spacing d11/7~1/5.
The chin spoiler is equally spaced, and the angle theta between chin spoiler and Moving plate is 45o~75o, chin spoiler Top and baffle upper plate top spacing d2For adjacent baffle upper plate spacing d11/8~1/6.
Circular aperture aperture is 1~2mm on the baffle upper plate, and pitch of holes is 1.5~2.5mm.
The acanthopore is rectangular evenly distributed on chin spoiler, and through-hole aperture is 1~2mm, pitch of holes for 1.5~ 2.5mm。
The liquid distribution trough is cylindrical shape, and surrounding is disposed with 6 groups of circle pores from top to bottom, and every group includes 7 Pore, pore aperture are 0.4~0.5mm.
Compared with prior art, it is an advantage of the invention that：By changing the flow path of gas-liquid fluid, rotor is made full use of Interior radial direction and axial space improve gas-liquid situation unevenly distributed, effectively extend gas-liquid contact time；Meanwhile pass through increase 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 is radially by outer Inwardly successively alternately through baffle upper plate and chin spoiler, liquid then radially from inside to outside successively alternately through chin spoiler and Baffle upper plate.Liquid enters liquid distribution trough after the pore of 0.4mm sprays, and forms the larger spraying of specific surface area, effectively Ground increases gas-liquid interface area, enhances the gas-liquid mass transfer effect of equipment.
（2）After spray impingement to the chin spoiler with acanthopore, under the influence of centrifugal force, liquid is in acanthopore and deflector Upper to form thin liquid film rather than laminar flow is formed on deflector, partially liq impinges upon next baffle upper plate across acanthopore, greatly Part is flowed along chin spoiler, increases the gas liquid interfacial area on each chin spoiler；Meanwhile gas can be by acanthopore Liquid film is blown brokenly, draws thinner by liquid film, and there are angles, liquid between chin spoiler and Moving plate under the influence of centrifugal force, to pass through Acanthopore forms liquid film in the outside of chin spoiler, increases the surface utilisation of gas liquid interfacial area and deflector.
（4）In centrifugal field, gas is constantly sheared when by fluid channel between acanthopore and upper chin spoiler And dispersion, counter current contacting between the channel formed with liquid in deflector, occur strong mixing, the interaction between gas-liquid Enhancing, the enhancing of gas phase less turbulence, mass transferring in gas phase process are strengthened.
（5）Filling filler is not needed to, reduces the cost of manufacture of device, reduces operation energy consumption, and rotator inertia is shown It writes and reduces, operation stability is improved, can long-time continuous operation.
