Center is equipped with circulation pipe seal pot and inner circulating tube, the inner circulating tube and outer tube wall at center in the eddy flow bubble tower phase reactor
Between be equipped with spiral shape guide vane, the reflecting plate with curve guide vane is equipped at inner circulating tube lower part outlet.
Wherein, interior On The Cycle Working Process is:
When work, aperture or micropore distribution device are supplied by air blower, and bubble rises, while containing under bubble castering action
There is the three-phase mixed flow body of solid to flow up, forms spiral shape under the guidance of spiral shape guide vane and rise, reach upper separation zone
Afterwards, unreacted gas is separated with the solid that liquid and reaction generate.Since solid-liquid mixed fluid liquid level at this time is followed higher than center
The liquid level of endless tube seal pot, therefore fluid-mixing enters center loop pipe and flows downward, and meets in center loop bottom of the tube exit
To after reflecting plate 10, under the guidance of 10 upper curve guide vane of reflecting plate, become direction component velocity radially and tangentially, formation is prewhirled.
The bubble that aperture or micropore distribution device generate pushes the fluid-mixing prewhirled to rise, into subsequent cycle.
Should during, the bubble of rising causes bubble deformation, increases gas since liquid tangential velocity acts on bubble
Liquid contact area improves the utilization rate of carbon dioxide.The prewhirl tangential direction component velocity of generation of mixed liquor is conducive to greatly simultaneously
The solid of particle with the separation of liquid, causes bulky grain to be deposited to the settling zone of reactor lower part under the action of the centrifugal force.
The outer circulation course of work is:
Jet stream distribution device is arranged in outside reactor, and ejector outlet protrudes into 0.3 in eddy flow bubble tower center loop pipe~
It 0.5 meter, when work, recycles pump startup, generates negative pressure when at the trunnion that liquid is shunk through ejector in outer circulation water tank, sucking contains
The tail gas of carbon dioxide, the tail gas of sucking is cut into after minute bubbles to be sufficiently mixed with liquid by liquid to react, and is bubbled into eddy flow
In tower central tube, the liquid that the outflow of gas-liquid mixture high speed will drive surrounding in exit flows downwardly together, center loop pipe
The interior downward flow velocity of mixed liquor is 0.35~1.5m/s, and when flow velocity is greater than 0.35m/s, bubble of the diameter less than 5mm can follow liquid
Body moves downwardly together；And when flow velocity is greater than 0.7m/s, bubble of the diameter less than 8mm can follow liquid to move to downwardly together
The outlet of center loop pipe, mixture flows up after reflecting plate, reaches gas-liquid separation behind top, and most of liquid flooding returns outer
Cyclic water tank forms outer circulation.Small portion of fluid flows downward through center loop pipe, constitutes interior circulation.
During being somebody's turn to do, the bubble being mixed in mixed liquor first moves downward after entering central tube, after arrival reflecting plate again upwards
It rises, hence it is evident that increase the time of contact of bubble and liquid；Simultaneously because water pressure increases, bubble volume is caused to reduce, specific surface
Product increases, and improves mass-transfer efficiency, is conducive to the raising of utilization rate of carbon dioxide.
