Evenly distributing on plane section, as shown in Figure 4.When liquid level is horizontal or when tower tray 301 tilts on tower tray 301,
It necessarily will appear the non-uniform situation of liquid level, the liquid level in some places is high, and the liquid level in some places is low, the high place of liquid level
First reach the first tooth socket 2021 on the top of outer barrel 202.If no first tooth socket 2022 in 202 top of outer barrel, then its
Area of passage is bigger, and therefore, the high local flow velocity of liquid level is larger, and Biased flow phenomenon is than more serious.The outer barrel 202 of the application
Top border is provided with several first tooth sockets 2021, when the high place of liquid level reaches the first tooth socket of lowest point on tower tray 301
2021, liquid phase stream starts to carry out overflow from this, since the first tooth socket 2021 reduces area of passage, on tower tray 301
Liquid level it is raised very fast, the liquid level on tower tray 301 will set up balance quickly, and reduction overflow gas-liquid allotter 200 is to tower
The dependence of disk levelness, it is ensured that with the presence of liquid phase in the circumferential direction of overflow gas-liquid allotter 200, to improve the distribution of overflow gas-liquid

The service-domain of gas-liquid allotter 200 is flowed, the pressure of distributor is effectively reduced in energy needed for distributor dispersed material is effectively reduced
Power drop.More specifically, the height of necking down nozzle 2012 can just allow ejection gaseous stream cover Taper Pipe 2022 bottom end,
If the height of necking down nozzle 2012 is too high, the flow velocity for being sprayed onto the gaseous stream of the bottom end of Taper Pipe 2022 will be lower, be unfavorable for by
Liquid phase stream dispels into drop, if the height of necking down nozzle 2012 is too low, the gaseous stream of ejection is directly through Taper Pipe 2022
The purpose that liquid phase stream is dispelled into drop is not achieved in bottom end.
Preferably, the floor projection shape of the first tooth socket 2021 is triangle, square, rectangle or semicircle.Wherein
The floor projection shape of one tooth socket 2021 is that the effect of triangle is best, and level is just considered as " V " shape.At work, using this
The tooth socket of kind " V " shape, area of passage are gradually increased from the bottom up.When liquid level reaches " V " shape bottom, due to this shape

Liquid separation body is flowed down from gap location, and a part flows down after flowing through the second tooth socket 2023, therefore the second tooth socket 2023 can make continuous liquid
Phase logistics is converted into discrete fluidised form, is passed through between hole convenient for gaseous stream at this time, so as to gaseous stream and liquid phase stream
Mixing, the drop for being formed liquid phase stream after splash, is conducive to the dispersion of gas-liquid.
More specifically, the floor projection shape of the second tooth socket 2023 is triangle, level is just considered as " V " shape.In work
When making, using the second tooth socket 2023 of this " V " shape, it is equivalent to and is provided with a circle sawtooth in 2022 bottom end of Taper Pipe.Work as liquid flow
When through the second tooth socket 2023, since " V " shape texture grooves and convex portion have corner angle, although liquid phase stream has certain
Surface tension, but be easy to puncture liquid film in edges and corners, it is more easier to convert discrete fluidised form for continuous liquid phase stream, more
Be conducive to the dispersion of gas-liquid.
Another preferred embodiment of the utility model is that the bus of Taper Pipe 2022 is pushed up with the bus for splashing cone 203 along cone 203 is splashed
The angle of angular direction is 10 ° -90 °, and the apex angle for splashing cone 203 is 90 ° -170 °.Specifically, when drop is from the bottom end of Taper Pipe 2022
At an angle hit splashes cone 203 after ejection, after drop, which bumps against, splashes cone 203, since the speed of drop is larger, has certain
Impact force, drop can further fragmentation, formed the smaller drop of partial size.In addition drop is touched at an angle with cone 203 is splashed
It hits, tiny drop can not only be formed under the influence of the impact force, and the drop after collision can be to splash 203 buses of cone
Normal is that center line is reflected, and having can collide between certain angle and the droplet of speed again, generate more refinement
Small drop.Drop can be oriented to farther place by the corner angle for splashing cone 203, realize the more uniform of droplet distribution.
More specifically, the bus of Taper Pipe 2022 with splash the bus of cone 203 along the angle for splashing 203 apex angle directions of cone be 50 °-
70 °, the apex angle for splashing cone 203 is 100 ° -150 °.If the bus of Taper Pipe 2022 splashes 203 apex angle directions of cone with the bus edge for splashing cone 203
Angle it is too small, then angle after droplet collision, close to the bus for splashing cone 203, dispersion is closer；If Taper Pipe 2022
Bus and the bus for splashing cone 203 are excessive along the angle for splashing 203 apex angle directions of cone, although the dynamics of collision is bigger, after collision
Liquid drop speed loss it is larger, be also unfavorable for being distributed to farther place, thus above range setting Taper Pipe 2022 and splash cone
203 can make the dispersion effect of drop preferable.
