Abstract
The utility model is related to pilot scale rectifier unit field, refers in particular to a kind of pilot scale rectifier column reflux than control device, including rectifying column, condenser, return flow meter, reactor effluent stream gauge；Rectifying column is connected with condenser, and rectifying tower top gaseous phase is condensed into liquid phase；Condenser is connected with return flow meter and reactor effluent stream gauge respectively by a threeway, discharging flow is controlled using liquid level overflow, so as to stabilize the liquid level difference between overflow liquid level and reflux pipeline, the return flow that regulation return flow meter valve opening is stablized under stable liquid level difference, under stable feed rate, return flow and stable tower reactor power, discharging flow is also stablized quickly；After such scheme so that the control of the reflux ratio of pilot scale rectifying experiment can more fast and stable.
Description
Technical field
The utility model is related to pilot scale rectifier unit field, refers in particular to a kind of pilot scale rectifier column reflux and compares control device.
Background technology
Large-scale rectifier unit of the pilot scale rectifier unit by laboratory lab scale rectifier unit excessively into industrial production.Carrying out
During pilot scale rectifying experiment, reflux ratio is quickly controlled into stabilization, the faster stable operation of pilot scale rectifying experiment can be made.Therefore,
The present inventor develops a kind of pilot scale rectifier column reflux than control device, and thus this case produces.
The content of the invention
To achieve these goals, the technical solution of the utility model is as follows：
A kind of pilot scale rectifier column reflux is than control device, including rectifying column, condenser, return flow meter, reactor effluent stream gauge；
Rectifying column is connected with condenser, and rectifying tower top gaseous phase is condensed into liquid phase；Condenser is flowed with backflow respectively by a threeway
Gauge and the connection of reactor effluent stream gauge, by controlling return flow meter to adjust reflux ratio；Reactor effluent stream gauge is connected with discharge tank.
Further, there is difference in height between described condenser and refluxing opening.
Further, there is one section of inverted U pipeline between described reactor effluent stream gauge and discharge tank.
Further, return flow is controlled by return flow meter, and discharging flow is that condenser has liquid with inverted U TOP
Potential difference, so that overflow is flowed out.
After such scheme, the utility model compared with prior art, with advantages below：
Quickly the reflux ratio of pilot scale rectifying experiment can be controlled stable so that whole pilot scale rectifying experiment faster stablizes fortune
OK.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Label declaration：
Rectifying column 1, condenser 2, return flow meter 3, reactor effluent stream gauge 4, discharge tank 5, pipeline 6, U-tube 7.
Embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.
As illustrated, a kind of pilot scale rectifier column reflux that the utility model is disclosed is than control device, including rectifying column 1, it is cold
Condenser 2, return flow meter 3, reactor effluent stream gauge 4, rectifying column 1 is connected with condenser 2, and condenser 2 is connected with pipeline 6,6 points of pipeline
Do not connected with return flow meter 3 and reactor effluent stream gauge 4, reactor effluent stream gauge 4 is connected with inverted U pipe 7, inverted U pipe 7 and discharge tank 5
Connection.
The gas phase of the top of rectifying column 1 out by condenser 2 into liquid phase, using condenser 2 and rectifier column reflux mouthful and U
The difference in height at the top of type pipe 7, the liquid part from condenser 2 out flows back to rectifying column, another portion by return flow meter 3
Divide and flowed to by reactor effluent stream gauge 4 in discharge tank 5.
Stable tower reactor heating power and feed rate, make the fluid flow condensed in condenser 2 stable, by reactor effluent stream gauge
4 standard-sized sheets, liquid level has difference in height with the top of inverted U pipe 7 in pipeline 6, and discharging flow is flowed out by overflow, the liquid level in pipeline 6
There is Metacentre Height poor with rectifier column reflux mouthful, return flow makes reflux ratio fast and stable required by adjusting return flow meter 4
Value.
Specific embodiment of the utility model is above are only, but design concept of the present utility model is not limited thereto, it is all
The change of unsubstantiality is carried out to the utility model using this design, the row for invading the utility model protection domain all should be belonged to
For.
