Have a fixed gap bottom calotte with column plate, its gas-to-liquid contact process can be described as: gas enters in cover from plate hole, by gap at the bottom of calotte
The lifting liquid that enters, broken, to answer back to cover simultaneously and hit, gas-liquid two-phase is hard hit, broken, turbulence in cover, and surface is more
New fast, beneficially gas-to-liquid contact；Then gas-liquid sprays from calotte side opening, and liquid phase, by scattered a large amount of droplets, is greatly improved
Mass transfer area, the gas-liquid between calotte further promotes mass transfer to spray simultaneously；Liquid phase drops back into column plate, and gas phase rises to one
Layer column plate.
But we have found that when reality is applied New-VST type column plate when carrying out gas-liquid mass transfer, due to from upper strata column plate downspout
The liquid phase of middle outflow can flow freely in tray surfaces, and the liquid phase completing gas-liquid mass transfer flows out without mass transfer with from downspout
Easily there is back-mixing in liquid phase ingredient, and due to installation accuracy and the impact of mass transfer disturbance so that the liquid layer thickness of tray surfaces is uneven,
And in the case of the ventilation of all calottes is basically identical, liquid layer thickness inequality can cause the mass-transfer efficiency of part calotte to reduce,
Therefore existing New-VST type column plate is improved, improve and improve the mass-transfer efficiency of all calottes in column plate, and reduce liquid phase
Back-mixing become problem demanding prompt solution in prior art.
