Description
Technical field
The present invention relates to petrochemical industry produce in fractional distillation process device of spiral-screen column, belong to technical field of petrochemical industry.
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, as novel distillation tower, has low energy consumption and the huge advantage of low cost for multicomponent rectification.At present
It is mainly used in ternary mixture to separate, partitioned column is the longitudinally disposed one piece of dividing plate in common rectifying column along tower, every
Plate will be divided into the subregions such as left and right two in the middle part of tower body, compared to common rectifying column, the uprising gas of dividing plate tower bottom will
It is allocated in dividing plate both sides, the gas apportioning cost of dividing plate both sides affects the product purity in distillation process and energy consumption, suitable
The energy consumption that gas apportioning cost not only can reduce partitioned column can also be significantly increased the purity of rectifying product.
Iris type rectifying column, due to the complexity of its structure and technique, creates more operation frees degree, energy-conservation and obtaining
Take highly purified product not a duck soup, need the controllability of internal system variable higher, cause iris type rectifying column every control
Problem becomes a principal element hindering its commercial Application, particularly will enter the uprising gas of dividing plate tower bottom in dividing plate
Both sides are allocated, and this apportioning cost affects product purity and energy consumption in distillation process, and suitable gas apportioning cost not only may be used
With reduce partitioned column energy consumption, the purity of rectifying product can also be significantly increased, the air flow rate of both sides how to distribute and
Effective control problem becomes industry focus of attention.With respect to common rectifying column, iris type rectifying column need to adjust simultaneously every
Plate upper end drops to the liquid of dividing plate both sides and bottom of towe rises to the gas of dividing plate both sides.Adjust because gas distributes in dividing plate both sides
Section is related to the series of computation processes such as complicated elevation computation, the dynamic analog of operating parameter, the analysis in gas-liquid two-phase flow field,
Thus, there is very high difficulty in the distribution regulation and control of dividing plate both sides gas.
At present, the mode that commonly used gas freely distributes in dividing plate both sides, the ratio freely distributing is by partitioned column
Portion's component（As packed height, the column plate number of plies, flow channel area etc.）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 is automatically assigned to dividing plate both sides.
Allocation proportion due to the change of feed composition and state and liquid etc. all can become the weight of impact gas distribution
Want factor, thus the gas flow ratio automatically distributing in dividing plate both sides usually can not reach the optimum operating conditions of partitioned column.
Gas distribution regulation and control are that the special inner member of design to adjust gas phase distribution to change dividing plate both sides pressure drop composition
Purpose, for example, the bottom of dividing plate install one piece can with the baffle plate of shift position, changed by the change in location of this baffle plate every
The circulation area of plate both sides, thus changing gas phase distribution ratio, places to change dividing plate both sides using inner member or by eccentric for next door
Pressure drop, not only its operating flexibility is less, sensitivity is low, and the mechanical wear being led to due to baffle plate movement is 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 document,
This dividing plate fractionating column includes tower body, gas phase is collected and distribution structure and liquid phase collection and distribution structure, and wherein, gas phase is collected and divided
Join and mainly pass through the bypass gas phase pipeline with regulating valve and flowmeter outside tower, combine automatically control the distribution realizing gas and
Control.This technical scheme major defect is：Firstly, since gas phase is drawn and gas phase is again introduced in tower being required to set in Ta Nei
Put gas phase apparatus for redistributing, so increased the complexity of tower height and internals；Secondly, for produce disposal ability larger every
Plate tower, the diameter of bypass 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 also will become sufficiently complex, pressure drop
Conference leads to 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 fall.
Chinese patent 201320829355.2 disclose a kind of for the gas allocation device in partitioned column, using flow inspection
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 this 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, adjusts that 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, leads to square valve block governor motion to be difficult to realize sane regulation；Due in tower
Drive disk assembly, lubrication and wear problem is had relatively to be difficult to resolve the long period normal operation that certainly can affect equipment.
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 complicated, effective distribution in dividing plate both sides for the gas and robust control are to ensure that product
Product index and the important means of reducing energy consumption, are badly in need of having advanced technological means to solve this industrial problem.
