Wherein, 1-tower body, 2-mass-transfer zones, 3-liquid distributors, 4-seal pots, 5-liquid traps, A-fluid inlet, B-
Gas phase import, C-liquid-phase outlet, D-gaseous phase outlet, hollow arrow indicate that liquid phase, filled arrows indicate gas phase.
Specific embodiment
The present invention is described in detail with reference to the accompanying drawing, but not limited to this.
As shown in Figure 1, a kind of gas-liquid mass transfer device of the embodiment of the present invention, described device includes: tower body 1, more than two biographies
Matter unit group, independent liquid trap, independent seal pot and gas group partition；Gaseous phase outlet D and fluid inlet A is equipped at the top of tower body 1,
Bottom is equipped with liquid-phase outlet C and gas phase import B；The mass transfer unit group includes liquid trap 5, seal pot 4, liquid distributor from top to bottom
3 and mass-transfer zone 2；The independent liquid trap is identical as the liquid trap 5 in mass transfer unit group, in independent seal pot and mass transfer unit group
Seal pot 4 it is identical.
Described two above mass transfer unit groups are arranged in the vertical direction inside tower body 1, independent liquid trap and independent seal pot position
In the lower section of bottom mass transfer unit group, gas barrier plate is located at the two sides of mass transfer unit group and is connected with liquid trap, so that often
One air inlet is formed on the top of one mass transfer unit group, and a gas outlet is formed on the bottom of each mass transfer unit group；
Liquid trap 5 and seal pot 4 in mass transfer unit group are combined with the head height of setting, form fluid-tight in operation,
The head height of fluid-tight is greater than the equivalent pressure loss conversion head height of two mass-transfer zones 2, so that gas phase will not pass through liquid collecting
Fluid-tight that device 5 and seal pot 4 are formed and form short circuit, it is ensured that realize the cocurrent cooling operation in mass-transfer zone 2；In addition to equipment downtime
When can discharge the liquid of storage, 4 bottom of seal pot is provided with aperture；The mass-transfer zone 2 is column plate, random packing or regular fills out
Material；
Deionized water to deoxygenation enters the gas-liquid mass transfer device from the fluid inlet A of tower top, and stripping vapor is from institute
The gas phase import B for stating the bottom of the device side enters, under described device bottom steam surmounts along uprising gas channel rapid increase
After square mass-transfer zone 2, the blocking of the fluid-tight by liquid trap 5 and seal pot 4 is turned back rapidly, with the liquid declined from 4 overflow of seal pot
Body mixing enters in lower section mass-transfer zone 2 from top to bottom.When mass-transfer zone 2 is using column plate, gas is since the pressure of itself is in column plate
Tapping spray from top to bottom.Since the direction that gas sprays is consistent with liquid flow direction, can eliminate in counter-current operation then
Concerning Flooding Phenomenon, the kinetic energy of gas can also be made full use of to promote the contact between gas-liquid two-phase, mass transfer enhancement, and gas no longer
It is to be bubbled by thicker liquid layer, so reducing plate pressure drop, reduces mist entrainment, improve mass transfer effect.When
When mass-transfer zone 2 is using filler, gas will carry under one's arms cocurrent flow descending in the fluid channel that liquid is formed in filler section, and liquid is drawn
It is distributed in filler surface at liquid film, thereby increases the contact area between gas-liquid two-phase, and reduce mist entrainment and pressure
Drop, eliminates liquid flooding.After gas-liquid mixture reaches lower section 2 bottom of mass-transfer zone, due to the pressure in the fluid-tight and entire tower of bottom
Power control, gas-liquid two-phase will separate, and liquid will continue traveling downwardly, into independent liquid trap and independent seal pot overflow to tower
Then bottom is drawn from the liquid-phase outlet C of described device bottom, gas, which is then turned back, surmounts top into uplink in gas passage
After mass-transfer zone 2, the blocking of the fluid-tight by liquid trap 5 and seal pot 4 is turned back again, with the liquid declined from 4 overflow of seal pot
Mixing enters in top mass-transfer zone 2 from top to bottom, carries out mass transfer next time.When gas-liquid mixture reaches top 2 bottom of mass-transfer zone
Afterwards, since the pressure control in fluid-tight and entire tower, gas-liquid two-phase will separate, liquid will be continued traveling downwardly, into fluid-tight, so
Overflow is to lower section mass-transfer zone 2 afterwards, and gas is then turned back again enters tower top by uprising gas channel, then from top gaseous phase
Export D discharge.
In the specific implementation process, the structure of the quantity of mass-transfer zone 2, seal pot 4, liquid trap 5 and liquid distributor 3, mass-transfer zone 2
The specification and size of interior column plate or filler require to select after being calculated according to the actual situation.
The present invention includes but is not limited to above embodiments, it is all carried out under the principle of spirit of that invention it is any equivalent
Replacement or local improvement, all will be regarded as within protection scope of the present invention.
In conclusion the above is merely preferred embodiments of the present invention, being not intended to limit the scope of the present invention.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
