The utility model discloses the difficult problem that operating flexibility is little, the adjustment of production technical scheme is difficult and three above multicomponent material separation device investment is big, the energy consumption is high that take division board rectifying column devices such as combined non - of multistage of gas -liquid modulator had solved the rectifying column device.
Description
Technical field
The utility model is related to the device of spiral-screen column of fractional distillation process in petrochemical industry production, belongs to petrochemical technology neck
Domain.
Background technology
In chemical separation process, rectifying column is most widely used fractionation separation equipment, but defect is to invest big, energy consumption
Higher, in the industries such as oil refining, petrochemical industry, the ratio that its energy consumption accounts for overall process is even as high as 70%, and equipment investment is more than 50%.
Partitioned column has low energy consumption and inexpensive huge advantage as novel distillation tower for multicomponent rectification.At present
Ternary mixture separation is mainly used in, partitioned column is the longitudinally disposed one piece of dividing plate along tower in common rectifying column, every
Tower body middle part is divided into the subregions such as left and right two by plate, and compared to common rectifying column, the uprising gas of dividing plate tower bottom will
It is allocated in dividing plate both sides, product purity and energy consumption in the gas apportioning cost influence distillation process of dividing plate both sides are appropriate
The energy consumption that gas apportioning cost can not only reduce partitioned column can also be significantly increased the purity of rectifying product.
Iris type rectifying column generates more operation frees degree due to its structure and the complexity of technique, energy-conservation and obtains
The product not a duck soup of high-purity is taken, it is necessary to the controllability of internal system variable is stronger, cause iris type rectifying column every control
Problem becomes a principal element for hindering its commercial Application, will particularly enter the uprising gas of dividing plate tower bottom in dividing plate
Both sides are allocated, and product purity and energy consumption in this apportioning cost influence distillation process, appropriate gas apportioning cost not only may be used
To reduce the energy consumption of partitioned column, the purity of rectifying product can also be significantly increased, the air flow rate of both sides how to distribute and
Effective control problem turns into industry focus of attention.Relative to common rectifying column, iris type rectifying column need regulation simultaneously every
The liquid and bottom of towe that plate upper end drops to dividing plate both sides rise to the gas of dividing plate both sides.Adjusted because gas is distributed in dividing plate both sides
Section is related to the series of computation processes such as elevation computation, the dynamic analog of operating parameter, the analysis in gas-liquid two-phase flow field of complexity,
Thus, there is difficulty very high in the distribution regulation and control of dividing plate both sides gas.
At present, generally using gas by the way of dividing plate both sides are freely distributed, the ratio for freely distributing is by partitioned column
Portion's component（Such as packed height, the column plate number of plies, flow channel area）With the operation operating mode decision in tower, the rising gas of bottom of towe
Body will comply with the equal rule of left and right sides pressure drop and be automatically assigned to dividing plate both sides.
The weight of influence gas distribution can all be turned into due to the change of feed composition and state and the allocation proportion etc. of liquid
Factor is wanted, thus the optimal operating conditions of partitioned column can not be usually reached in the gas flow ratio that dividing plate both sides are distributed automatically.
Gas distribution regulation and control are that the special inner member of design adjusts gas phase distribution to change dividing plate both sides pressure drop composition
Purpose, for example, dividing plate bottom install one piece can with the baffle plate of shift position, changed by the change in location of the baffle plate every
The circulation area of plate both sides, so as to change gas phase distribution ratio, dividing plate both sides is changed using inner member or by the eccentric placement in next door
Pressure drop, not only its operating flexibility is smaller, sensitivity is low, and due to mechanical wear caused by baffle plate movement so that equipment can not
Long-period stable operation.
A kind of dividing plate fractionating column and its gas-liquid flow control methods are disclosed in PCT/US2011/056079 patent documents,
The dividing plate fractionating column includes that tower body, gas phase are collected and distribution structure and liquid phase collection and distribution structure, wherein, gas phase is collected and divided
With mainly by the bypass gas phase pipeline with regulating valve and flowmeter outside tower, with reference to automatically control the distribution of realizing gas with
Control.The technical scheme major defect is：Firstly, since gas phase is drawn and gas phase is again introduced into being required to be set in Ta Nei in tower
Gas phase apparatus for redistributing is put, so increased the complexity of tower height and internals；Secondly, for production disposal ability it is larger every
Plate tower, the diameter for bypassing gas phase pipeline can be very big, and associated components are installed and maintenance is inconvenient；Again, for regulating valve and
The bypass gas phase pipeline of flowmeter, not only increases tower height, and the characteristic of gas flow pressure drop will also become sufficiently complex, pressure drop
Conference causes the downspout liquid flooding below dividing plate, and system is by cisco unity malfunction；Finally, the size of regulating valve is with unit scale
And change, investment will become sufficiently expensive, and can not sensitively and accurately regulate and control gas phase flow rate in the range of lower drag drop.
Chinese patent 201320829355.2 discloses a kind of gas allocation device in partitioned column, is examined using flow
Survey device, controller, cylinder, dividing plate, square separate slot, downspout, inlet channel, square valve block governor motion, sleeve, rotating shaft,
Motor and gas distribution mechanism.The design defect that the device is primarily present is：There is performance of control curve not in adjusting gas flow
Rule, it is not easy to realize fine setting, regulation control law is poor, the defect such as tolerance is non-linear；The resistance drop of dividing plate both sides gas is anti-
Should be delayed, square valve block does not possess fine setting characteristic, causes the sane regulation difficult to realize of square valve block governor motion；Due in tower
There is drive disk assembly, lubrication and wear problem are relatively difficult to resolve and can certainly influence the long period of equipment to run well.
Aforementioned barriers formula rectifying column thermal coupling technological operation variable is more, and many parameters intercouple, dividing plate both sides
Gas flow and its dependent variable physical relation it is complicated, gas is to ensure to produce in effective distribution of dividing plate both sides and robust control
The important means of product index and reducing energy consumption, urgent need has advanced technological means to solve this industrial problem.
