Description
Technical field
The present embodiments relate to industrial technical field more particularly to a kind of gas-liquid contact apparatus.
Background technology
Absorptions, dedusting, cooling are realized by air-flow and liquid phase contact, are desorbed, are traditional chemical engineering unit operation means,
Mass-transfer efficiency in these operating process between gas-liquid is often relied on the gas-liquid contact surface of rational design and highly enriched interface
Less turbulence.
It is to realize that gas-liquid comes into full contact with most ancient, most using packed tower in existing air-flow and liquid phase contact arrangement
Ripe method, this method is that gas-liquid contact is carried out in filling batch, and gas-liquid contact mass transfer is carried out in the wetted surface of filler.
The structured packing of reasonable design can realize good gas-liquid contact, still, packed tower in smaller bed height at present
Single layer bed height has certain limitation.If single layer bed is too high, it is non-uniform to be easy to the gas-liquid contact occurred in bed
Phenomenon, i.e. liquid tend to tower wall flowing, are reduced so as to cause the liquid among single layer bed, generate " dry cone " phenomenon, greatly drop
The effect of low gas-liquid contact.In order to solve the problems, such as " dry cone ", traditional filling batch can be modified to form in layer,
Liquid distribution is re-started between every layer of bed.But, so that the vertical height of filling batch is got higher, and increases device fabrication
With the cost of installation.

The device spirally column plate realize air-flow spiral, come into full contact with the liquid stream of decline, fallen in very low air-flow pressure
Obtain preferable gas-liquid contact effect.Rotating stream tray scrubber achieves extensive commercial Application in dedusting, desulfuration field.However, rotation
The size of flowing plate tower cannot be too big, otherwise it cannot be guaranteed that liquid is uniformly distributed.When requiring the tolerance of processing very big, usually need
Will in a tower the multiple rotating stream tray scrubbers of arranged in parallel, this makes the processing of entire gas-liquid contact apparatus more difficult, and structure is more
It is complicated.
In addition, the devices such as eddy flow packed bed and spiral liquid film venturi are also the common dress for realizing efficient gas-liquid contact
It sets.In high-speed rotation process, the surface turbulence of gas-liquid contact greatly enhances eddy flow filling batch, and only several millimeters can obtain
The gas-liquid mass transfer effect of one piece of theoretical plate.However, due to the high speed rotation of eddy flow filling batch, be not used at all Wind Volume with
And the industrial operation of high liquid measure.In addition, spiral liquid film venturi is during realizing efficient gas-liquid contact, there are pressure drop compared with
High problem.
Synthesis, for how while realizing efficient gas-liquid contact, avoids the occurrence of it is found that at present in industrial circle
Higher pressure drop, liquid blocks, phenomena such as liquid distribution is uneven and gas-liquid contact apparatus is of high cost and complicated, is still
A problem to be solved.
