In a first aspect, an embodiment of the present invention provides the device of sulfur dioxide and butadiene in a kind of recycling cyclobufene sultone,
As shown in Figure 1, which includes condenser 1 and exports the first recycling can 2 being connected with condenser 1 by pipeline, should
Device further includes：Vacuum flashing kettle 3, first pressure control valve 5, jet pump 6, circulating pump 7, the second recycling can 8, pressure control system
System 9, wherein, the import of vacuum flashing kettle 3 passes through pipeline and the outlet of cyclobufene sultone reactor 4；First pressure control valve 5
It is arranged on the pipeline of 3 entrance of vacuum flashing kettle；The import of jet pump 6 is connected by the gas outlet of pipeline and vacuum flashing kettle 3
Logical, gas liquid outlet passes through pipeline and the inlet communication of condenser 1；The import of circulating pump 7 is gone out by pipeline and the first recycling can 2
Mouthful connection, outlet by pipeline simultaneously with the inlet of jet pump 6 and the inlet communication of cyclobufene sultone reactor 4；Second recycling
Tank 8 is connected by pipeline with the liquid outlet of vacuum flashing kettle 3；Control pressurer system 9, for measuring 3 inner cavity of vacuum flashing kettle
Pressure, and the stream of the mixture of liquid phase sulfur dioxide and butadiene in jet pump 6 is inputted by circulating pump 7 to adjust according to pressure
Amount, so drive adjustment jet pump 6 aspirate the gas phase sulfur dioxide exported by vacuum flashing kettle 3 and butadiene mixture stream
Amount, and then adjust the pressure of 3 inner cavity of vacuum flashing kettle within a preset range.
Just the work of the device of sulfur dioxide and butadiene is former in recycling cyclobufene sultone provided in an embodiment of the present invention below
Reason, which is given, to be described：
Start control pressurer system 9 first so that the pressure of 3 inner cavity of vacuum flashing kettle within a preset range (pressure
Preset range is vacuum or micro-positive pressure, to ensure being normally carried out for vacuum flashing), first pressure control valve 5 is then controlled, is made
The cyclobufene sultone that is exported by cyclobufene sultone reactor 4, sulfur dioxide, butadiene mixture enter in vacuum flashing kettle 3, due to
The boiling point of sulfur dioxide and butadiene is more much lower than cyclobufene sultone, and the vacuum flashing processing through vacuum flashing kettle 3 can obtain liquid
Trim on the mixture of phase cyclobufene sultone and the mixture of gas phase sulfur dioxide and butadiene, gas phase sulfur dioxide and butadiene
In the top of 3 inner cavity of vacuum flashing kettle, liquid phase cyclobufene sultone is located at the lower part of 3 inner cavity of vacuum flashing kettle due to gravity.So
The mixture of gas phase sulfur dioxide and butadiene is sucked up to by the gas outlet of vacuum flashing kettle 3 in jet pump 6 by pipeline afterwards,
It liquefies later into condenser 1, then the mixture of liquid phase sulfur dioxide and butadiene enters first by pipeline by condenser 1
Recycling can 2, further into circulating pump 7, a part of liquid phase sulfur dioxide and the mixture of butadiene exported by circulating pump 7
Into in cyclobufene sultone reactor 4, to synthesize cyclobufene sultone again, the mixture of a part of liquid phase sulfur dioxide and butadiene exists
It under the action of control pressurer system 9, is again introduced into jet pump 6, and is mixed with the mixture of gas phase sulfur dioxide and butadiene,
Then it is again introduced into condenser 1, repetitive cycling.In the process, the vacuum flashing that control pressurer system 9 is obtained according to measurement
The pressure of 3 inner cavity of kettle, adjustment input liquid phase sulfur dioxide and the mixture of fourth two in jet pump 6 by pipeline by circulating pump 7
Flow, to adjust the flow that jet pump 6 aspirates the gas phase sulfur dioxide exported by vacuum flashing kettle 3 and butadiene mixture, into
And adjust the pressure of 3 inner cavity of vacuum flashing kettle, be in preset range, with ensure input cyclobufene sultone, sulfur dioxide,
Vacuum flashing can occur for the mixture of butadiene.
At the same time, liquid phase cyclobufene sultone is inputted by the liquid outlet of vacuum flashing kettle 3 in the second recycling can 8 by pipeline.
It should be noted that the preset range of the chamber pressure of vacuum flashing kettle 3 be vacuum or micro-positive pressure, less than to its
The cyclobufene sultone of interior input, sulfur dioxide, butadiene mixture pressure, so as to be realized under conditions of nearly vacuum degree to mixed
Close the vacuum flashing of object.The gas outlet of vacuum flashing kettle 3 and liquid outlet are located at the top and bottom of vacuum flashing kettle 3 respectively, with
Convenient for the gas phase sulfur dioxide after vacuum flashing and the mixture of butadiene and liquid phase cyclobufene sultone respectively by vacuum flashing kettle 3
Top and lower part input downstream line in.The flow for inputting the mixture of liquid phase sulfur dioxide and butadiene in jet pump 6 is big
When, by a large amount of gas phase sulfur dioxide of winding and the mixture of butadiene, therefore can be by adjusting the liquid phase two of entrance jet pump 6
The flow of the mixture of sulfur oxide and butadiene is adjusted into the gas phase sulfur dioxide of jet pump 6 and mixing for butadiene to drive
The flow of object is closed, and then adjusts the pressure of 3 inner cavity of vacuum flashing kettle, the pressure is made to meet vacuum flashing condition, ensures cyclobutane
Sulfone, sulfur dioxide, butadiene mixture through vacuum flashing processing be divided into liquid phase cyclobufene sultone, gas phase sulfur dioxide and butadiene
Mixture.
Based on it is above-mentioned it is found that it is provided in an embodiment of the present invention recycling cyclobufene sultone in the device of sulfur dioxide and butadiene,
By setting vacuum flashing kettle 3 and first pressure control valve 5, pressure and entrance convenient for 4 inner cavity of control cyclobufene sultone reactor
The flow of cyclobufene sultone, sulfur dioxide, butadiene mixture in vacuum flashing kettle 3 is handled through 3 vacuum flashing of vacuum flashing kettle
Afterwards, convenient for liquid phase cyclobufene sultone is detached with the mixture of gas phase sulfur dioxide and butadiene, to input the second recycling can 8 respectively
And in jet pump 6.By setting jet pump 6, convenient for aspirating the gas in vacuum flashing kettle 3 under the control of control pressurer system 9
