There is one or more snippets, the density of aperture, the pattern in hole and structural parameters can be according to the kinds with when fluid of gas-liquid fluid in pipe
Class is selected.
When carrying out gas-liquid separation, technical solution is: fixing separator using inlet flange 2 and outlet(discharge) flange 16 and pacifies
After dress, solution-airmixture enters separator inner cylinder 1 by separator inlet first, the solution-airmixture after one stage impeller 3
Rotary motion is generated, the biggish liquid phase of density is thrown on the inner wall of inner cylinder 1 under the influence of centrifugal force, the lesser gas of density
Phase-polymerization forms gaseous core.After liquid zone section 5, partially liq is discharged into the ring cavity between outer barrel 14 and inner cylinder 1,
After by gravity fall, through 17 drain separator of drain port, to realize first separation.After drain section 5, most of gas
Mainly pass through the wheel shaft through-hole of sencond stage impeller 4 with a small amount of liquid and enter gas phase channel, continues up, liquid and a small amount of gas exist
Spin intensity further strengthens under the action of 4 blade of sencond stage impeller.Later, separation under the conditions of high air content and low gas content amount
Process difference, carries out described separately below.
Under the conditions of low gas content amount, solution-airmixture is mostly in relatively stable fluidised form in inner cylinder 1, liquid and
After sencond stage impeller 4, spin intensity increases a small amount of gas, and centrifugal force further enhances, under the influence of centrifugal force density compared with
Big liquid is thrown on the inner wall of outer barrel 14, and partially liq is continued up due to inertia, by level-one sorting hole
After the blocking of plate 8, under gravity and after entering the ring cavity between outer barrel 14 and inner cylinder 1, through separator liquid phase outlet
17 are discharged separator, and the setting for hiding water ring 12 can effectively avoid liquid phase and be reentered in inner cylinder 1 during falling；And gas
Body moves upwards, and by the through-hole of three-level separation orifice, most separator is left through separator gas phase outlet 15 afterwards, to realize
And secondary separation.After most of gas and a small amount of liquid enter gas phase channel by the wheel shaft through-hole of sencond stage impeller 4, gas is carried
A small amount of drop continues up.In 7 exit of core cylinder, gas carry a small amount of drop after the effect of skimming baffle 13,
Into separator outer barrel upper chamber 18, the ring cavity entered inside and outside separator between cylinder is further fallen after rise under gravity
In, separator is left by separator liquid phase outlet 17；Gas then leaves separator through separator gas phase outlet 15, finally
Realization separates three times.
Under the conditions of high air content, solution-airmixture is mostly in that mix stream or annular flow etc. unstable in inner cylinder 1
Fluidised form under.Under this fluidised form, solution-airmixture has the characteristics that oscillation, easily carries.In order to avoid inner cylinder 1
The structure of high vibration and separator is damaged, and shockproof strip 6 is provided between inside and outside cylinder, plays fixed branch to inner cylinder 1
Support effect.Liquid and a small amount of gas are after sencond stage impeller 4, and spin intensity increases, and centrifugal force further enhances, in centrifugal force
The effect biggish liquid of lower density is thrown on the inner wall of outer barrel 14, due to inertia, oscillation, gas and carrying etc., portion
Liquid separation cognition continues up along 14 inner wall of outer barrel, three layers of separation orifice can barrier liquid move upwards.Separation orifice
Structure it is as in Figure 2-4,8 through-hole of level-one separation orifice is provided with the side on the inside of the level-one separation orifice, the second-order separation
9 through-hole of orifice plate is provided with the side on the outside of the second-order separation orifice plate, and the through-hole on three-level separation orifice 10 is uniformly distributed and leads to
Bore dia gradually becomes smaller inwardly from outside.Level-one separation orifice 8 directly stops the liquid used upwards along 14 inner wall of outer barrel；
After level-one separation orifice 8, still there is partially liq to be continued up by the carrying of gas, the second-order separation orifice plate 9 is mainly used
In the liquid that blocking is continued up through level-one separation orifice 8；On the one hand the setting of three-level separation orifice 10 can stop to be bullied
On the other hand the drop that the influence that body carries continues up can make the liquid entered in separator outer barrel epicavate 18
Uniformly fall after rise.By the barrier effect of three-level orifice plate, most part liquid, which is fallen after rise, to be entered between outer barrel 14 and inner cylinder 1
Ring cavity, a small amount of drop into separator outer barrel upper chamber 18 are fallen after rise under gravity, and enter outer barrel 14 with
Ring cavity between inner cylinder 1 most leaves separator through separator liquid phase outlet 17 afterwards, realizes secondary separation.Hide water ring 12
Setting can effectively avoid liquid phase and reentered during falling in inner cylinder 1.
After most of gas and a small amount of liquid enter gas phase channel by the wheel shaft through-hole of sencond stage impeller 4, high-speed motion
Gas carries a small amount of drop and continues up.In 7 exit of core cylinder, a small amount of gas of carrying directly impacts skimming baffle
13, skimming baffle 13 is fixed using skimming baffle lacing wire 11.After the effect of skimming baffle 13, the drop of the carrying of gas enters
Separator outer barrel upper chamber 18 further falls after rise in the ring cavity entered inside and outside separator between cylinder under gravity,
Separator is left by separator liquid phase outlet 17；Gas then leaves separator through separator gas phase outlet 15, final real
It now separates three times, is finally reached and refines isolated purpose.
