Description
Technical field
The present invention relates to the technical field of the gas-liquid separation in chemical industry more particularly to a kind of efficient degassing towers.
Background technique
At present both at home and abroad there are many kinds of gas-liquid separating methods, there are several types of gravitational settlings, baffling for main principle to be separated
Separation, centrifugal force separate, silk screen separation, ultra-filtration and separation, filler separation etc., but integrate there are two types of separation principles:
1, (such as weight sedimentation, baffling separate) is separated to mixture using constituent mass (weight) is different, mainly
Mechanism is density difference: since gas is different from the density of liquid, the quality of gas is smaller than the quality of liquid under same volume.Weight
The principle of power sedimentation is: since gas is different from the density of liquid, for liquid when flowing with the gases, liquid will receive gravity
Effect, generate a downward speed, and gas is still flowed towards original direction, that is to say, that liquid and gas are in weight
Has the tendency that separation in the field of force, downward liquid is attached to pool together on wall surface and be discharged by delivery pipe.
2, (such as silk screen separation, ultra-filtration and separation) is separated to mixture using disperse system particle size difference.Main machine
Reason is intermolecular distance difference: the molecule coherent condition of liquid and the molecule coherent condition of gas are different, gas molecule apart from farther out,
And fluid molecule distance wants much closer, so gas particle is smaller than liquid particle.Its principle is: close due to gas and liquid
Degree is different, and when liquid flows together with gas mixing, if encountering blockings, gas is understood baffling and walked, and liquid is due to inertia, after
Continuous to have a forward speed, forward liquid, which is attached to, to be stopped on wall surface to lead to since the effect of gravity pools together downwards
Cross delivery pipe discharge.
Domestication industrial and commercial bank owner will carry out gas-liquid separation to mixture using disperse system particle size difference at present.Gas-liquid point
From exemplary apparatus mainly have void tower degassing tower, material filling type degassing tower, vacuum degassing tower etc..Wherein, void tower degassing tower is using weight
The separation principle of power sedimentation, has the disadvantage in that low separation efficiency, equipment volume are huge and occupied space is more.Material filling type is de-
Gas tower has the disadvantage in that replacement is difficult, the easy blocking of packing layer, segregational load using isolated separation principle is filled
Narrow range is more than after gas-liquid mixture regulation flow velocity, and separative efficiency sharply declines, resistance ratios gravitational settling is big.Vacuum degassing machine
Using baffling separation principle, have the disadvantage in that it is at high cost, be not suitable for the biggish occasion of tolerance, equipment sealing performance wanted
Ask stringent.
