Description
1. technical field
The present invention provides a kind of solid valve tower plate of protecting against shock stripping of layer steam injection, is related to petroleum refining field.
2. background technology
In the equal phase separation of chemical industry, gas-liquid mixed phase charging is the operating mode that destilling tower is most commonly encountered, such as atmospheric and vacuum distillation
Tower.Gas-liquid mixed phase feed distributor, which carries, efficiently separates the vapour in charging, liquid two-phase, while vapour phase is good along tower section acquisition
Distribution well, liquid phase also have a good collection and distribution effect.Good tower feed segment structure can not only stabilizer operation,
But also the separating effect of tower can be improved.But due to flash temperature, pressure, room and time limitation, flash distillation is difficult once to reach
To balance, existing Deethanizer design is difficult to ensure that flash efficiency reaches 100%.As crude oil dodges under the best flash conditions of atmospheric distillation tower
It steams efficiency highest and only can reach 75%, a large amount of light compositions, which mix, to be needed to inject less steam in tower stripping section in the liquid phase
It is pulled out.Stripping section gas-liquid contact main purpose and is up to make light component contained by normal bottom liquid phase escape as far as possible
Flash zone is detached as flash distillation gas phase enters upper rectifying section, cuts into different qualified fractions.And it existing column plate and fills out
Expect that the operating conditions primarily directed to rectifying section atm number are developed and designed, applies big, narrow-minded in stripping section liquid flowing strength
In operating conditions, it is difficult to which guarantee does not leak or pound substantially leakage, and gas-liquid contact is insufficient, and liquid dispersing surface product is small, and update is slow, institute
It is difficult to escape containing light component, steam stripping efficiency is low or fails, and bottom of tower liquid level is unstable, and operation difficulty is big, larger (such as stripping steam of energy consumption
Dosage is big or reboiling temperature is high)；And filler not anti-clogging.Therefore the operating conditions of stripping section and material properties determine it most
Good mass transfer component can only be column plate.
Such as atmospheric and vacuum distillation, under normal circumstances, 350 DEG C of the true boiling point of crude oil should be extracted with front-end volatiles in atmospheric tower, but real
On border due to atmospheric tower flash distillation be difficult it is primary reach balance and stripping section tower internals is inefficient or failure, air-distillation yield is often
The product yield shown in true boiling-point (TBP) evaluation data is not achieved.It is less than 350 DEG C in the normal bottom ash oil of domestic each atmospheric distillation plant
Lighter component content generally 6%~15%, in depressurizing a line distillate, it sometimes appear that 350 DEG C before quantity of distillate be up to
60% or more, one line oil of decompression is included in light receipts or is sold separately as product by some refineries, causes part should normal pressure extraction
Component is transferred to vacuum tower, not only increases vacuum furnace thermic load, but also can increase vacuum tower vapour phase load, pressure drop and charging
The entrainment of section and the energy consumption of atmospheric and vacuum distillation unit, reduce the yield of straight-run diesel oil, reduce the vacuum degree of vacuum tower vaporization section,
Influence vacuum tower extracting rate.
For the big liquid measure of stripping section, small tolerance, easily blocking and the separation requirement different from rectifying section, the present inventor 1998
Using trapezoidal solid valve and it is oriented to inclined hole combination, is led by low trepanning high gas velocity multiple spot steam injection, the dispersion of reinforcing gas-liquid impingement and gas
Stream increases the measures such as contained light component effusion probability, has invented domestic and international the first and currently the only high efficiency, low pressure drop, height
The solid valve stripping column plate (ZL99214583.x) with guiding role of flux, high operating flexibility, it is residual can effectively to reduce bottom of tower
Light component content in liquid reduces steam or boils vapour dosage again, reduces energy consumption, to solve plate column or packed tower stripping section effect
The low problem of rate, different structure band was oriented to the patents and patent applications of fixed float valve plate in succession later, as ZL02291525.7,
ZL200620081665.0, ZL200520125580.3 etc..But it is the fixation float valve of the punching press on column plate, column plate with The upper column plate
Thickness and connection structure are identical as common column plate, since the unexpected bumping of stripping section steam, column plate punching are turned over, fallen off in commercial Application
And damage, it is difficult to ensure the stable long-term operation of stripping section.In addition it is small to consolidate valve latasuture airflow counter-collision, liquid surface renewal rate
It is low, it is unfavorable to light component release contained by liquid.
There is an urgent need for exploitation protecting against shock, strengthen the special column plate of High efficiency stripping that liquid surface updates, steam consumption is few, effectively reduces
Light component content in tower bottoms, it is ensured that device stable long-term operation.
3. invention content
A kind of layer steam injection invented the purpose of the invention is to overcome the shortcomings of the solid valve tower plate technique of existing stripping
The solid valve tower plate of protecting against shock stripping, strengthen liquid surface update, effectively reduce light component content in tower bottoms, reduce steam or
Vapour dosage is boiled again, reduces energy consumption, it is ensured that the stable long-term operation of device.
